Mysterious, 10-million-light-year-long magnetic field connects two galaxy clusters — Scientists have detected radio waves emanating from the space between a pair of galaxy clusters—evidence of intergalactic magnetic fields and fast-moving particles in the space between these giant galactic assemblages. Even more mysteriously, the feature the scientists detected is tens of times longer than the distance that a relativistic electron can travel in its lifetime. ~ It’s pizza delivery!
Self-repairing rechargeables —Researchers in Japan have developed a self-repairing material that could extend the lifespan of batteries. Professor Atsuo Yamada at the University of Tokyo, Japan, has invented an oxygen redox-layered oxide (Na2RuO3) that could allow rechargeable batteries to last much longer as it’s self-repairing. ~ OK, next I want self-recharging.
Accumulated mutations create a cellular mosaic in our bodies — Mutations, most of them harmless, accumulate in our tissues over a lifetime. The subtle genetic variations in cells make humans a mosaic. Your body has about 40 trillion cells which all arose from a single fertilised egg. But the DNA in many of those cells is no longer a perfect clone of that original one. ~ So it It turns out you aren’t simply a clone of the cells you started with.
Pumping heart patch —A ‘pumping’ patch containing millions of living, beating stem cells could help repair the damage caused by heart attacks, according to researchers.
Sewn on to the heart, the 3cm (1in) by 2cm patch, grown in a lab from a sample of the patient’s own cells, then turns itself into healthy working muscle. ~ Rabbits recommend …
Ancient plague bacteria sequenced — Scientists have gained some insight into one of the first known calamities to visit mankind: a two century-long pandemic caused by the bacterial disease plague. Studying the remains of plague victims, the researchers say they were able to sequence the genomes of plague strains that devastated the Roman Empire starting in the 6th century. They also found direct evidence the plague’s destruction made it as far as England. ~ Maybe this item belongs in The Apocalypticon.
Salamander goo makes amazing medical glue —When Chinese giant salamanders are injured, they discharge white mucus from glands on their skin. New research shows this sticky salamander goo makes an excellent medical glue, sealing wounds and encouraging them to heal. Using the glue, scientists were able to close bleeding skin incisions in less than 30 seconds. ~ Current medical glues make wounds hot, they’re not elastic enough and can be toxic.
Scientists locate neutron star collision that could have created our solar system’s plutonium — in 2017, observatories around the world observed a high-energy collision between a pair of dense objects, each slightly more massive than the Sun but only the size of a city. A similar collision closer to home could have been responsible for producing some of the heaviest elements in our own solar system – and scientists think they know when it happened.
Using measurements of what’s left of these elements in ancient meteorites, a pair of researchers worked backward to locate the neutron star merger that produced some of them. ~ The abundances of these elements spiked approximately 80 million years before the solar system formed.
Water worlds could have very deep oceans —Scientists have good reason to believe that so-called water worlds – exoplanets with surfaces covered entirely by a single gigantic ocean – are common in the galaxy. But new computer simulations suggests that not only are water worlds prevalent, they’re also teeming with water – and at mind-boggling scales. Imagine oceans hundreds, and even thousands, of kilometres deep. ~ That’s no reason for Kev to make a movie, though. Water worlds are still hypothetical.
Data on protein — By 2020, researchers estimate that the world’s digital archive will weigh in at around 44 trillion gigabytes. That’s an astounding amount of data that isn’t necessarily being stored in the safest of places. Most storage mediums naturally degrade over time (if they’re not hacked or accidentally destroyed) and the cloud isn’t as reliable as companies want us to believe.
So researchers at Harvard University have turned to some unique chemistry they believe could safely archive the world’s data for millions of years — without requiring any power. Chemists at Harvard University took inspiration from nature and came up with a way to store data using oligopeptides: molecules made up of amino acids that are considerably smaller and easier to work with than DNA. ~ Getting pumped? Shake it, baby.
An end to AIDS may be within sight —A landmark study found men whose HIV infection was fully suppressed by antiretroviral drugs had no chance of infecting their partner. The findings support the message of the international U=U campaign that an undetectable viral load makes HIV untransmittable. ~ A major step forward.
Pinholes aid holographic transmission — Researchers in South Korea have designed an ultrathin display that can project dynamic, multi-colored, 3D holographic images. ~ This suggests holographic displays could be projected from thin devices like cell phones.
One-step method for biodegradable plastics — Researchers in Japan and the Netherlands have devised a one-stop method to produce plant-derived plastics. Bio-based plastics are emerging as a next generation material and are expected to replace petroleum-derived plastics. A plant-derived polyester, called polyethylene furanoate (PEF), is a promising polymer derived from plants that can replace the current favourite of the plastic industry, polyethylene terephthalate (PET). ~ Pfft.
Astonishing Densiovan fossil — The archaeology world has been abuzz with news of the first Denisovan fossil found outside Siberia. The 160,000-year-old jawbone was uncovered by a Buddhist monk in a Chinese cave nearly 40 years ago.
Now that it has finally been studied, it’s known it belonged to a young Denisovan individual who occupied the cave some 160,000 years ago. ~ Home Sapiens date back 200,000 years.
New research describes the remains of a gigantic, four-legged mammalian carnivore that terrorised Africa 22 million years ago —Simbakubwa kutokaafrika, which translated from Swahili means ‘big lion coming from Africa.’ But this was no feline: it belonged to an extinct group of mammals known as hyaenodonts, which have no close relation to any species of mammalian carnivore living today. Larger than a polar bear, and with a head as big as a rhino’s, Simbakubwa spent its time as an apex predator in Eastern Africa around 22 million years ago, eventually going extinct under mysterious circumstances. ~ Honestly, record keeping back then was all over the place.
Popping corks at CERN — Scientists have announced the observation of “CP violation in a D0 meson” at CERN, a discovery that will appear in physics textbooks for years to come. So?
The universe is full of regular matter. There’s also antimatter, which exists even here on Earth, but there’s much less of it. This new observation is important on its own, but it also takes physicists another step closer to explaining where all the antimatter has disappeared to. ~ D0, a Meson, a CP violation, Ray, a …
Kazakhstan meteorite hid evidence of ancient solar super flare — Scientists found evidence of an ancient solar “superflare” hidden in a meteorite first found in Kazakhstan in 1962. Meteorites can be useful for telling the story the Solar System’s history through the elements they contain. By analysing the Efremovka meteorite, a pair of researchers determined a superflare that occurred around 500,000 years after the Sun’s birth could have emitted as many x-rays as the largest solar flare each second, but for perhaps an entire year. ~ On the bright, well very bright, side: free X-Rays.
Twisted graphene is exciting stuff — Carbon sheets only a single atom thick, called graphene, take on a pair of important physical properties when they are twisted at just the right ‘magic’ angle relative to one another.
If the atmosphere this month at the world’s largest physics conference was any indication, twisted graphene has now spawned an entirely new field of physics research. ~ But is it recyclable?
Teeny-tiny Bluetooth transmitters —Battery-powered and energy-harvesting millimeter-scale sensors are meant to last for years without needing replacement, but their radios can’t muster the energy needed to communicate using even the lowest energy version of Bluetooth, called Bluetooth Low Energy (BLE). But now engineers at the University of Michigan have built the first millimetre-scale stand-alone device that speaks BLE. Consuming just 0.6 milliwatts during transmission, it would broadcast for 11 years using a typical 5.8-millimeter coin battery. ~ Teeny-tiny trackers, in other words.
Old human brains still make new cells — Humans can make fresh brain cells well into their 90s, but the production of new neurons falls in those with Alzheimer’s, even when the disease has recently taken hold, scientists have found. The findings may help doctors to diagnose Alzheimer’s at an earlier stage. ~ OK, brain, make me some new ones right now.
Booze without the bad effects —Alcarelle, a synthetic alcohol that should provide the relaxing and socially lubricating qualities of alcohol without the hangovers, health issues and the risk of getting paralytic, is starting to look like a possibility. ~ Cheers to that.
Gene editing record —Using a modified version of CRISPR, a team of geneticists has successfully triggered 13,200 genetic changes to a single human cell. That’s a new record, and by a long shot. This sweeping new editing process could eventually be used to strip DNA of useless or dangerous genetic information – or create entirely new kinds of life. ~ Oh, wait, will we get singe-cell humans? Lol.
Corn-starch plastic heals itself with a blast of heat — Researchers from the Leibniz Institute for New Materials in Saarbrücken, Germany, and from the nearby Saarland University, turned to corn starch to help develop a new lacquer coating that can bounce back from minor damage. ~ Boom-shacka-lacquer, oh yeah!
Five AI experiences you can try now in a browser — It can be hard to get your head around exactly what AI does and how it can be deployed though, which is why we present to you these five fun online experiments — all you need is a web browser and a few minutes to see some of the party tricks AI is already capable of. ~ Hmm, yeah.
Origin of the Universe — NASA has announced it will create a new telescope mission, the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer. Luckily we can call it SPHEREx for short. It’ll look at how our universe has changed, and how common the ingredients of life are in the Milky Way. ~ Maps it.
Another Arctic crater, 35kms across — NASA glaciologists used topographical maps, satellite images, and radar scans to analyse an area of the Arctic and found a flat, bowl-shaped depression in the bedrock. This was surrounded by an elevated edge and characteristic central peaks, which form on the crater floor after an impact. The crater has eroded significantly over time, causing the team to estimate it was created somewhere between a hundred thousand years and a hundred million years ago. ~ Those big white bits of Earth must be easier to aim at.
A new kind of magnet —It has been theorised for decades, and now may have been experimentally proven to exist. It could eventually lead to better data storage devices. In a normal magnet, the magnetic moments of individual grains align with each other to generate a magnetic field. In contrast, in the new “singlet-based” magnet, magnetic moments are temporary in nature, popping in and out of existence. ~ I like singlets, especially in this weather, but they singularly fail to make me more of an attractant.
The most important car you’ve never heard of — According to Gizmodo, the Autobianchi Primula (main picture, above) is perhaps the most technically influential car ever, because the fundamental theory and design of that car dictated the template that most modern cars use today. Fiat built almost 75,000 Primulas between 1964 and 1970. ~ And now, I have heard of it. But to me it looks rather distressingly like an Austin 1100.
Smart sneakers not dumb — The right shoe of every pair of UnderArmour HOVR shoes contains a chip that connects with the Map My Run app (also owned by Under Armour). With it, you can keep track of metrics like distance, pace, splits, cadence, and stride length. ~ You know you want ‘personal gait coaching’!
Cutting connection — Internet entrepreneur Arianna Huffington sees a bright future for a new kind of technology — the kind that helps individuals disconnect from the damage done by the internet’s first generation. And it can’t come soon enough, she says, as the next generation of technology may pose an ever greater threat to our lives and jobs. ~ So the next big thing in tech might be tech that lets us disconnect from tech …
Tinder for cows —UK farming start-up Hectare has launched its own equivalent for livestock. It’s called ‘Tudder‘. The app features data profiles of animals from 42,000 UK farms in an effort to help farmers find the perfect breeding partner for their cattle. ~ Cud-dle time.
The planetary health plate — This is a diet put together by scientists as a general guide for how to feed a projected 10 billion humans in 2050 while also keeping the planet from keeling over. It consists largely of vegetables and whole grains. ~ This has pretty much been my diet for the last 30 years. What are you doing?
‘New’ dinosaur — Living 140 million years ago in the early Lower Cretaceous, the newly discovered herbivore Bajadasaurus pronuspinax had a thing for growing spikes. It was part of the Sauropod family, but looked a little like a small Brontosaurus crossed with a porcupine. ~ OK, then.
Farout is really far out — For the first time, an object in our solar system has been found more than 100 times farther than Earth is from the sun.
The International Astronomical Union’s Minor Planet Center announced the discovery Monday, calling the object 2018 VG18. But the researchers who found it are calling it ‘Farout.’
They believe the spherical object is a dwarf planet more than 310 miles in diameter, with a pinkish hue. That colour has been associated with objects that are rich in ice, and given its distance from the sun, that isn’t hard to believe. Its slow orbit probably takes more than 1000 years to make one trip around the sun. ~ It sounds cold.
Mars crater filled with ice — The stunning Korolev crater in the northern lowlands of Mars is filled with ice all year round owing to a trapped layer of cold Martian air that keeps the water frozen. The 80-km-wide (50-mile-wide) crater (main picture, above) contains as much water ice as Great Bear Lake in northern Canada, and in the centre of the crater the ice is more than 1.6kms (one mile) thick.
~ Whiskey on that?
Best quantum computer yet?A startup based in Maryland has released and tested an impressive new quantum computer that demonstrates the power of an occasionally overlooked quantum computing architecture. ~ Yeah, that’s true, I had overlooked that.
Norway Is Entering a New Era of Climate-Conscious Architecture — The country now has a suite of buildings that generate more energy than they use. Powerhouse Brattørkaia is an ‘energy positive’ building that will open to the public next year in Norway.
The European Union has a target of making all new buildings zero-energy by 2020, but in Norway, carbon neutrality isn’t enough.
A consortium in Oslo made up of architects, engineers, environmentalists, and designers is creating energy-positive buildings in a country with some of the coldest and darkest winters on Earth. “If you can make it in Norway, you can make it anywhere,” says Peter Bernhard, a consultant with Asplan Viak, a Powerhouse alliance member. ~ Well, if anyone’s going to be climate conscious!
Dinosaur feathers — Feathers were common among dinosaurs, but scientists aren’t certain if the fur-like coverings of pterosaurs – a group of flying reptiles – were of the same sort seen on dinos and birds or something completely different. The discovery of two exquisite fossils in China now suggests pterosaurs were very much covered in feathers, potentially pushing back the origin of this critically important evolutionary feature by 70 million years. ~ Wonder if they were as brightly coloured as parakeets?
Mission to Bennu may help defend Earth, and there may be water there — Bennu is a 487.68m-wide asteroid that orbits the Sun relatively close to the Earth. NASA’s OSIRIS-REx mission won’t just take pretty pictures of the asteroid Bennu, it will also help scientists learn whether the rock will one day threaten Earth. OSIRIS-REx spacecraft also detected evidence of water on its target just a week after arriving. ~ To wetly threaten Planet Earth …
Quark soup droplets expand like Big Bangs — Stars and galaxies didn’t form right away. Scientists think that matter was initially a near-perfect fluid of quarks, the smallest known component of atoms. They have found evidence of these fluids in high-energy particle collider experiments. Now, evidence continues to mount that these liquids can form in unexpected ways, yielding tiny droplets that flow outwards explosively, like liquid Big Bangs in miniature. ~ Sounds like messy dining, though.
Experimental gene therapy stops mice getting fat — Researchers at Flinders University knocked out a gene known as RCAN1 in mice, hypothesising this would increase “non-shivering thermogenesis,” which “expends calories as heat rather than storing them as fat” – the mice were fed a high-calorie diet and did not gain weight. In particular, the modified mice did not store fat around their middles (a phenomenon associated with many health risks, including cardiac problems) and their resting muscles burned more calories. ~ Despite that, I don’t think I can bring myself to eat those skinny, gene-altered mice.
What did Minnesota kids from the year 1904 think would happen by the year 1919, or even 2019?They imagined fancy airships in the sky, “automobiles for everything,” and wondrous house-cleaning robots. They even imagined trips to Mars by the year 1919. Seriously. ~ I already have a wondrous house-cleaning robot. Me.
Incan temple virtually recreated — The 1500-year-old Pumapunku temple in western Bolivia is considered a crowning achievement of Mesoamerican architecture, yet no one really knew what the original structure actually looked like. Until now.
The stonework of the temple is considered so precise that ancient alien enthusiasts claim it was made by lasers and other extraterrestrial technologies. ~ The technique can now be used on other sites.
Two Chinese stalagmites enrich radiocarbon dating —Owing to the discovery of two stalagmites in a Chinese cave containing a seamless chronological atmospheric record dating back to the last Ice Age, radiocarbon dating will now be better.
An unbroken, high-resolution record of atmospheric carbon-12 and carbon-14 was found in a pair of stalagmites located within Hulu Cave near Nanjing, China, according to new research published in Science. ~ Now we can calibrate back a lot further.
Expanding universe mystery — An important discrepancy in measurements of the universe’s acceleration has theorists wondering whether we’ve gotten something fundamentally wrong in our understanding of the history of the universe.
One currently unexplained cosmological mystery is the ‘Hubble tension,’ where various measurements of the universe’s expansion seem to disagree. As the story surrounding this tension gets murkier, others have begun to come up with new ideas, but these attempts to explain away the difference without new physics don’t seem to hold up to scrutiny. ~ Yes, none of it holds up to mine.
3D-printed moon dust for Mars — Mars is lacking in the vast supply of natural resources we rely on here on Earth, and astronauts attempting to colonise, or even just visit, the red planet can only bring a limited supply of materials with them. The results of the European Space Agency’s latest 3D-printing experiments (main picture, above) prove it isn’t impossible, though. If there’s one thing Mars isn’t lacking, it’s dust. As a stand in for genuine Mars ingredients, researchers have turned to a simulated version of lunar soil, also known as lunar regolith. The ESA 3D-printed a sample of various parts using a light-sensitive binding agent mixed with the regolith (silicon, aluminium, calcium, and iron oxides that have been ground to a very fine dust). ~ Print me an Earth-bound ship!
Genetically-altered twins spark outrage — Twin girls born earlier in November had their DNA altered to prevent them from contracting HIV, according to an Associated Press report. If confirmed, the births would signify the first gene-edited babies in human history — a stunning development that’s sparking an outcry from scientists and ethicists. ~ He doesn’t appear to have been kidding. ‘Don’t worry, kids! We’re just going to infect you with HIV and see what happens …’
5 tech innovations that have changed music — Music is one of the fundamental appreciations that sets humans apart from every other living thing we’re currently aware of.
Beyond the artistry we connect with on an emotional level, there is a whole industry filled with gadgets, instruments and software that transforms the production and consumption of music. Read about five innovations that have revolutionised music in the last couple of decades. ~ Who needs musical ability when you have all this?
Harvard scientists solve age-old lens problem — Chromatic aberration is just a fact of life when it comes to photography. A combination of high-quality gear – lenses in particular – and user skill can minimise the tell-tale purple fringe. But what if a simple layer on your lens could all but eliminate CA? Enter a team of researchers from Harvard’s School of Engineering and Applied Sciences (SEAS), who have accomplished exactly this. ~ But it will take ages to reach consumers.
It’s all going to Apocalypticon in a handcart, but here are 5 innovations that can help save the oceans from plastic — The science and tech communities have also been collaborating with governments and big business on innovative solutions to stop the eight million tonnes of plastic that is dumped into oceans every year. ~ Humans work hard to solve ridiculous but terrible problems created by … yeah, humans.
Holiday spot for ExoMars 2020 mission selected — When it comes to landing a robot on another planet, perhaps the most important question is where to put the dang thing. The researchers behind the upcoming ExoMars mission, consisting of a rover and lander, have now announced their preferred location on the Red Planet.
ExoMars 2020 is the next part of the ExoMars missions: a rover and landing platform to be sent to Mars as part of a joint mission between the European Space Agency and Russia’s Roscosmos. ~ I dunno: no pool, and services are too far away.
Army space balloons — DARPA, the US military’s research arm, is currently testing a wind sensor that could allow devices in its Adaptable Lighter-Than-Air (ALTA) balloon program to spot wind speed and direction from a great distance and then make the necessary adjustments to stay in one spot.
DARPA has been working on ALTA for some time, but its existence was only revealed in September. “By flying higher we hope to take advantage of a larger range of winds,” says ALTA project manager Alex Walan. ALTA will operate even higher than Loon at 22,900 to 27,400 meters (75,000 to 90,000 feet or 14 to 17 miles) where the winds are less predictable. Statioanry, they could provide communication in remote or disaster-hit area, follow hurricanes, or monitor pollution at sea. One day, they could even take tourists on near-space trips to see the curvature of the planet. ~ Presumably, the balloons for Flat Earthers will be flat discs.
Plasma in their Chinese Experimental Advanced Superconducting Tokamak (EAST) reached a 100 million degrees Celsius — That’s six times hotter than the core of the Sun. This temperature is the minimum required to maintain a fusion reaction that produces more power than it takes to run. The Chinese research team said they were able to achieve the record temperature through the use of various new techniques in heating and controlling the plasma, but could only maintain the state for around 10 seconds. The latest breakthrough provided experimental evidence that reaching the 100 million degrees Celsius mark is possible, according to China’s Institute of Plasma Physics. ~ So this has great importance to humankind, because I reckon it would cook a pizza perfectly in a tenth of a second. Although I must admit the phrase ‘playing with fire’ also springs to mind.
Omnidirectional turbine wins award — A spinning turbine that can capture wind traveling in any direction and could transform how consumers generate electricity in cities has won its inventors a prestigious international award and a US$38,000 prize. Nicolas Orellana, 36, and Yaseen Noorani, 24, MSc students at Lancaster University, scooped the James Dyson award for their O-Wind Turbine, which, in a technological first, takes advantage of both horizontal and vertical winds without requiring steering. ~ I think they should call it ‘the wind bag’.
Tantalising but preliminary evidence of a ‘brain microbiome’ — We know the menagerie of microbes in the gut has powerful effects on our health. Could some of these same bacteria be making a home in our brains? The annual meeting of the Society for Neuroscience drew attention with high-resolution microscope images of bacteria apparently penetrating and inhabiting the cells of healthy human brains. The work is preliminary, and its authors are careful to note that their tissue samples, collected from cadavers, could have been contaminated. But to many passersby in the exhibit hall, the possibility that bacteria could directly influence processes in the brain – including, perhaps, the course of neurological disease – was exhilarating. ~ Yes, whatever floats your boats, brain peeps!
Dubai hover cops — Like a Sci-Fi thriller brought to life, Dubai has taken its police force to another level with fully functional Hoverbikes being added to the force by 2020.
It was only last year that the Dubai Police announced they were looking to upgrade their traffic patrol vehicles into Hoverbikes, but to have actually stuck to that promise and come out with some wicked cool tech in only a years time is pretty remarkable. ~ Crikey, you wouldn’t want to fall off into those props! (See main picture, above). And why? And won’t they whip up little sand storms?
Neanderthals were nicer than was thought — The stereotype of a typical Neanderthal life is that it was extraordinarily difficult, violent, and traumatic. But a comparative analysis of the remains left behind by Neanderthals and contemporaneous humans is finally overturning this unwarranted assumption.
Neanderthals have been depicted as club-carrying, dim-witted brutes who spent their days clobbering each other with reckless abandon.
New research published in Nature is finally setting the record straight, showing that Neanderthals and Upper Paleolithic modern humans experienced similar levels of head trauma. Yes, life was tough for Neanderthals — but the new research suggests life wasn’t any less tougher or violent for contemporaneous Homo sapiens. ~ So e tu, non Brutus!
Earth’s oldest soil —This could be tucked away in an ancient rock outcrop in Greenland, according to new research. Dating back some 3.7 billion years, the suspected soil – exposed underneath a retreating ice cap – could potentially contain fossilised traces of primordial life. ~ No! Don’t wash your boots!
Seyfert sucks up Earth-sized object — A team of physicists has reported an Earth-sized clump of matter flying into a black hole at nearly a third the speed of light. It’s a lucky observation: some scientists visualise smaller black holes as being like the black hole from the movie Interstellar – a massive, spinning, compact object surrounded by a disk of shredded gas and dust, looking much like an evil planet Saturn. Objects don’t fall directly into the black hole, but travel inward along these spinning clouds. But theoretical physicists predict that larger black holes might instead have “chaotic accretion”, meaning things can fall into them at any angle. ~ But where did the Earth-sized clump go after it went into the hole?
Japanese robots hop onto asteroid — Two tiny hopping robots successfully landed on an asteroid called Ryugu, then sent back some wild postcards from their new home. The tiny rovers are part of the Japan Aerospace Exploration Agency’s Hayabusa2 asteroid sample-return mission. Engineers with the agency deployed the robots early Friday September 21st, but JAXA waited until September 22nd to confirm the operation was successful and both rovers made the landing safely. ~ ‘We come in pieces …’
Solar-gathering battery — The problem of energy storage has led to many creative solutions, like giant batteries. For a paper published in the journal Chem, scientists trying to improve the solar cells themselves developed an integrated battery that works in three different ways: it can work like a normal solar cell by converting sunlight to electricity immediately; it can store the solar energy; and it can simply be charged like a normal battery. It’s a combination of two existing technologies: solar cells that harvest light, and a so-called flow battery. ~ I’m ever ready for this.
Spheres make concrete leaner and greener — Rice University scientists have developed micron-sized calcium silicate spheres that could lead to stronger and greener concrete, the world’s most-used synthetic material. The researchers formed the spheres in a solution around nanoscale seeds of a common detergent-like surfactant. The spheres can be prompted to self-assemble into solids that are stronger, harder, more elastic and more durable than ubiquitous Portland-style cement. The spheres are also suitable for bone-tissue engineering, insulation, ceramic and composite applications. ~ From that churning cement mixer to ‘please self assemble now …’
Spray-on antennas — In a study published in Science Advances, researchers in Drexel’s College of Engineering describe a method for spraying invisibly thin antennas, made from a type of two-dimensional, metallic material called MXene, that perform as well as those being used in mobile devices, wireless routers and portable transducers. ~ MXene it up, indeed.
A better mosquito trap — A scientist in Australia has come up with an insecticide-free way to control a particularly pesky species of mosquito. The approach involves two things: deploying a decidedly low-tech mosquito trap called a GAT … and getting to know your neighbours. ~ Nice to know you, neighbour! Now, stop yapping and start trappin’. [But people are still working on the modified extinction possibilities too.)
Maths and science boys and girls — A study of school grades of more than 1.6 million students shows that girls and boys perform similarly in science, technology, engineering and math (STEM) subjects. ~ Why is anyone actually surprised at this?
Don’t cut out that appendix! After more than a century of slicing tiny, inflamed organs from people’s guts, doctors have found that surgery may not be necessary after all – a simple course of antibiotics can be just as effective at treating appendicitis as going under the knife.
Peaking into mummies — A revved-up version of traditional CT scanning shows it’s possible to acquire microscopic-scale images of ancient Egyptian mummies, revealing previously unseen features such as blood vessels and nerves. ~ Seriously? I could have told them they’d have blood vessels and nerves!
Airborne lasers reveal many more Mayan structures — Using an airborne laser mapping technique called ‘lidar’, an international team of archaeologists has uncovered an astounding number of previously undetected structures belonging to the ancient Maya civilisation — a discovery that’s changing what we know of this remarkable society. ~ The ancient Maya’s range extended from what is today southern Mexico, Guatemala, and Belize.
According to World Health Organization data, China has overtaken the United States in healthy life expectancy at birth for the first time. The data from 2016 finds Chinese newborns can look forward to 68.7 years of healthy life ahead of them, compared with 68.5 years for American babies.
The United States was one of only five countries, along with Somalia, Afghanistan, Georgia and Saint Vincent and the Grenadines, where healthy life expectancy at birth fell in 2016, according to a Reuters analysis of the WHO data, which was published without year-on-year comparisons in mid-May. [I’m trying to get my head around 68.7-year-old babies.] Maybe Americans should ask for more surveillance?A high school in Hangzhou City, Zhejiang Province located on the eastern coast of China, has employed facial recognition technology to monitor students’ attentiveness in class, local media reports. Three cameras at the front of the classroom scan students’ faces every 30 seconds, analysing their facial expressions to detect their mood. The different moods – surprised, sad, antipathy, angry, happy, afraid, neutral – are recorded and averaged during each class. A display screen, only visible to the teacher, shows the data in real-time. A certain value is determined as a student not paying enough attention. Still sucks to be a girl, though. China’s gender gap is not confined to tech. The country’s gender parity ranking fell in 2017 for the ninth straight year, leaving China placed 100 out of 144 countries surveyed in a report by the World Economic Forum.
The country ranked 60th in terms of female labour force participation and 70th in terms of wage equality for similar work. Men on average had an estimated income of around $19,000, over $7000 more than women.
Samantha Kwok, the Australian-Chinese founder of the Beijing-based recruitment firm JingJobs, said clients often gave her two job descriptions: one to be published publicly and a second internal one that detailed requirements based on age or gender… A greenhouse gas is billowing into the atmosphere from a source somewhere in East Asia that no one can identify at a rate scientists have never before seen, and it’s ignited a scientific dash to get to the bottom of it. In 2014, mysterious toxic plumes of CFC-11 – a type of CFC – began to drift across the Pacific Ocean. [And who left the question mark off that headline, left?]
In the data wars, Google is reminding organisations to review how much of their Google Groups mailing lists should be public and indexed by Google.com since sensitive data is being exposed. The notice was prompted in part by a review that KrebsOnSecurity undertook with several researchers who’ve been busy cataloging thousands of companies using public Google Groups lists to manage customer support and in some cases sensitive internal communications. Google Groups is a service that provides discussion groups for people sharing common interests. Because of the organic way Google Groups tend to grow as more people are added to projects – and perhaps given the ability to create public accounts on otherwise private groups – a number of organisations with household names are leaking sensitive data in their message lists. Once, the Mad Men ruled advertising. They’ve now been eclipsed by Math Men: engineers and data scientists whose province is machines, algorithms, pureed data, and artificial intelligence. Yet Math Men are beleaguered, as Mark Zuckerberg demonstrated when he humbled himself before Congress, in April. Math Men’s adoration of data, coupled with their truculence and an arrogant conviction that their ‘science’ is nearly flawless [which has more to do with its money-making potential, I suspect],has aroused government anger much as Microsoft did two decades ago. Unknown third parties appear to be exploiting the Chrome Store’s ‘theme’ section to offer visitors access to a wide range of pirate movies including Black Panther, Avengers: Infinity War and Rampage. When clicking through to the page offering Ready Player One, for example, users are presented with a theme that apparently allows them to watch the movie online in ‘Full HD Online 4k’. Of course, the whole scheme is a dubious scam which eventually leads users to Vioos dot co, a platform that tries very hard to give the impression of being a pirate streaming portal but actually provides nothing of use. That’s why we all trust Google to build military drones, right? No? Coz that’s what’s happening. In March, Google signed a secretive agreement with the Pentagon to provide cutting edge AI technology for drone warfare, causing about a dozen Google employees to resign in protest and thousands to sign a petition calling for an end to the contract. Google has since tried to quash the dissent, claiming that the contract was “only” for US$9 million, according to the New York Times. Internal company emails obtained by The Intercept tell a different story: the September emails show that Google’s business development arm expected the military drone artificial intelligence revenue to ramp up from an initial US$15 million to an eventual US$250 million per year. Meanwhile, users in Europe have already filed complaints against Facebookand Google, saying the tech companies are in violation of the General Data Protection Regulation (GDPR). Apple approves Telegram update even after Russian government demands Apple shut the app down — Amidst a contentious battle with the Russian government over demands to pull Telegram, the encrypted message app, from the App Store, Apple has approved an updated version of the messaging app having seemingly blocked such changes for two months.
Excerpt from my forthcoming book: “Essentially, there are many threats that could wipe out huge numbers of humans. It’s worth recalling the dinosaurs were on the planet for around 60 million years before volcanoes and an asteroid wiped them out – Homo Sapiens has only been around for about 200,000 years. Yet, numbers of us may survive an apocalypse: we have done many times before.“
Asteroid from another star system found orbiting wrong way near Jupiter — Astronomers have spotted an asteroid orbiting our sun in the opposite (retrograde) direction to the planets. The 3.22km-wide (2-mile-wide) asteroid, 2015 BZ509, is the first “interstellar immigrant” from beyond our solar system to remain, according to the study published in the journal Monthly Notices of the Royal Astronomical Society. ~ Where are traffic wardens when you need them?
NASA’s new exoplanet hunter releases incredible first image — On the way to its final orbit around Earth, NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) sailed past the moon and snapped its first picture of space. TESS should be able to look at 200,000 stars in the 300 light-years around the Earth – and maybe this new shot (main picture, above) will show you what that really means. ~ I think that star 66th from the left, 1049 down bears closer examination…
German test reveals that magnetic fields are pushing the EM Drive — Researchers in Germany have performed an independent, controlled test of the infamous EM Drive with an unprecedented level of precision, and it turns out the thrust is coming from interactions with the Earth’s magnetic field. ~ We have all long awaited the ‘magnetic WTF thruster’ so this is exciting.
Gel-based robots can dance — Engineers at Rutgers University have started 3D-printing gel material that could one day give us softer, arguably less frightening robots. And to show off their so-called “smart gel,” they made it dance. It’s not just cute – the reactive synthetic might have far-reaching applications for the future of automation.
The printable ‘smart gel’ moves in response to electric stimuli. Made of a special polymer that reacts to electric impulses, the gel can be formed into a variety of shapes to perform tasks such as grabbing objects or moving them around. ~ Less frightening? I think a killer robot trying to kill me is not necessarily cuter if it’s made of gel, myself.
Scientist transfer memories from one snail to another — UCLA neuroscientists have transferred a memory from one snail to another via injections of RNA, a startling result that challenges the widely held view of where and how memories are stored in the brain. The finding from the lab of David Glanzman hints at the potential for new RNA-based treatments to one day restore lost memories and, if correct, could shake up the field of memory and learning. ~ But how fast, though?
Legend of Loch Ness Monster to be tested with DNA samples — For hundreds of years, visitors to Scotland’s Loch Ness have described seeing a monster that some believe lurks in the depths. But now the legend of ‘Nessie’ may have no place left to hide.
A New Zealand scientist is leading an international team to the lake next month, where they will take samples of the murky waters and conduct DNA tests to determine what species live there. University of Otago professor Neil Gemmell says he’s no believer in Nessie, but he wants to take people on an adventure and communicate some science along the way. ~ Besides, he says, his kids think it’s one of the coolest things he’s ever done.
Dinosaur-killing asteroid rewrote avian history — The asteroid that hit Earth 65 million years ago didn’t just suck for the big lizards. Shockwaves likely knocked down the trees, fires would have burned up entire forests, and less light would have meant fewer plants. Goodbye to homes for birds, then.
New research shows how the strike would have decided which species made it and which species didn’t. Without trees, only ground-dwelling birds would have survived. This surely would have had a profound impact on the kinds of species still around today – a bottleneck in evolution’s history that changed the course of life forever.
So, how smart was T-Rex anyway? Palaeontologist and evolutionary biologist Steve Brusatte shares his expansive knowledge by providing a concise and highly accessible overview of the dino era. Though extinct now, these remarkable creatures had a tremendous run, dominating the planet’s ecosystems for tens of millions of years. Dinosaurs flourished for over 150 million years, far, far longer than humans have been around, and they utterly dominated the planet and evolved into some of the most incredible feats of biology the world has ever seen. Many dinosaurs had big brains, implying high intelligence. ~ But could T-Rex bang a gong?
Using Relativity to magnify stargazing — Two teams of scientists report seeing single, twinkling stars in galaxies billions of light years away with the help of the Hubble Space Telescope. All they needed was Albert Einstein’s theory of general relativity. ~ And I thought that theory was about my Uncle Eddie.
Milky Way centre has loads of black holes — The supermassive black hole lurking at the center of our galaxy appears to have a lot of company, according to a new study that suggests the monster is surrounded by about 10,000 other black holes. ~ Holey heck.
The first 3d-printed steel bridge looks like it broke off an alien mothership — MX3D in Amsterdam just revealed the world’s first 3D-printed bridge. It’s made of a completely new type of steel, spans 12.19m (main picture, above), and will be installed early next year in De Wallen, the largest and best-known red-light district in Amsterdam. It also looks utterly otherworldly. ~ The pimps and pushers will be pleased.
Antarctic vegetables — As temperatures outside dipped to well below freezing, and as blizzards pounded the Antarctic research station, German scientists were carefully tending to a remarkable veggie garden – one requiring no soil or natural sunlight. The success of their first harvest, which produced vibrant-looking lettuce, radishes, cucumbers and other treats, represents a promising test run for similar greenhouses that could one day be built on Mars – or beyond. ~ Iceberg lettuce, anyone?
Archaeologists have now found ‘new’ Nazca lines with the help of drones — Peruvian archaeologists armed with drones have discovered more than 50 new examples of these mysterious desert monuments in adjacent Palpa province, traced onto the earth’s surface in lines almost too fine to see with the human eye. In addition, archaeologists surveyed locally known geoglyphs with drones for the first time – mapping them in never-before-seen detail. ~ It’s a sign.
Roman refrigerators — Archaeologists in Switzerland are conducting an experiment to figure out how ancient Romans used a series of deep shafts to keep food cool well into the summer months. The shafts were discovered in 2013 at Augusta Raurica, an archaeological site located near the Swiss city of Basel. The Roman colony was founded in 15 BC, and it soon blossomed into a vibrant metropolis and trade hub that was home to around 15,000 to 20,000 people. Today, Augusta Raurica remains one of the best-preserved Roman cities north of the Swiss Alps. ~ Really? To get cold in Switzerland, just walk up hill!
Four-eyed lizard — An ancient species of monitor lizard that went extinct some 34 million years ago had four eyes, according to new research. It’s the first time that scientists have ever seen such a thing in a jawed terrestrial animal – an observation that’s filling a gap in our understanding of how these features evolved. ~ Ah, but was four-eyed forewarned?
Rare supernova extinguishes star at record speed — Using data collected by the Kepler space telescope, an international team of astronomers led by Brad Tucker from Australian National University has documented the death throes of a star located 1.3 billion light-years away. Known as KSN 2015K, this unprecedented FELT reached its maximum brightness in just 2.2 days, which is 10 times faster than standard supernovae. ~ Or it’s a pretty full-on war in a distant galaxy …
Brown planet reopens debate — Scientists have discovered a planet a lot like Jupiter orbiting a dim star, if you can even call it a star – it’s nothing like our Sun. The finding once again makes us wonder: what is a planet, anyway? ~ I’m going with ‘big round thing in space that orbits and is not on fire’.
Alien DNA — If an alien life form is alien, how will we know what it is? DNA and RNA are the building blocks of life on Earth, but the molecules of life might differ substantially on another planet. So if scientists combing, say, the potentially habitable waters of Jupiter’s moon Europa were to stumble across a new life form, how could they know what they had discovered? Aha – scientists at Georgetown University suggest a method for identifying alien life using modern genome sequencing technology. ~ Please open your carapace, sir and/or madam, we would like to take a swab.
Cat-like ‘hearing’ with device tens of trillions times smaller than human eardrum — Researchers are developing atomically thin ‘drumheads’ tens of trillions of times thinner than the human eardrum able to receive and transmit signals across a radio frequency range far greater than what we can hear with the human ear. Their work will likely contribute to making the next generation of ultralow-power communications and sensory devices smaller and with greater detection and tuning ranges. ~ Have to go – I just heard my cat.
NVIDIA’s 2 Petaflop DGX-2 AI Supercomputer with 32GB Tesla V100 and NVSwitch Tech — NVIDIA CEO Jensen Huang recently announced a number of GPU-powered innovations for machine learning, including a new AI supercomputer and an updated version of the company’s powerful Tesla V100 GPU that now sports a hefty 32GB of on-board HBM2 memory. NVIDIA claims NVSwitch is five times faster than the fastest PCI Express switch and offers an aggregate 2.4TB per second of bandwidth. ~ All the better to monitor us with.
Bionic wheelbot — Using eight reconfigurable legs, the BionicWheelBot can creepily crawl along the ground, but then transform into a wheel and roll at an alarming speed. ~ It can tiptoe through tricky terrain then quickly roll through the flat bits.
A paperlike LCD is thin, flexible, tough and cheap — Optoelectronic engineers have manufactured a special type of LCD that is paper-thin, flexible, light and tough. With this, a newspaper could be uploaded onto a flexible paperlike display that could be updated as fast as the news cycles. It sounds futuristic, but scientists reckon it will be cheap to produce, perhaps only costing US$5 for a 5-inch screen. ~ I can almost guarantee the last word in its description will be gone by the time this becomes available.
Sewage sludge leads to biofuels breakthrough — Researchers have discovered a new enzyme that will enable microbial production of a renewable alternative to petroleum-based toluene, a widely used octane booster in gasoline that has a global market of 29 million tons per year. ~ Isn’t toluene also carcinogenic?
13,000-year-old human footprints found off Canada’s Pacific coast — Human footprints found off Canada’s Pacific coast may be 13,000 years old, according to a new study. The finding adds to the growing body of evidence supporting the hypothesis that humans used a coastal route to move from Asia to North America during the last ice age. ~ So that rules out flying.
Secrets of famous Neanderthal skeleton La Ferrassie 1 revealed — Anthropologists have provided new insights on one of the most famous Neanderthal skeletons, discovered over 100 years ago: La Ferrassie 1. Nearly all of the fractures were made post-mortem. La Ferrassie 1 was an old man (likely over 50 years old) who suffered various broken bones during his lifetime and had ongoing respiratory issues when he died. The skeleton was found in a burial pit and dated to between 40,000 and 54,000 years old. ~ The weight of sediments snapped the bones.
