Futurology ~ Bennu’s NASA visitor, shiny on Mars, cancer test, bee vaccine, coal mine farms, Californian solar, transplanted uterus, ancient Black Death


The Curiosity Rover found something super-smooth and shiny on the surface of Mars

NASA’s asteroid-sampling spacecraft has arrived at its target — NASA’s OSIRIS-REx has arrived at its target asteroid, Bennu, an important step on its mission to collect a sample from an asteroid and return it to Earth. OSIRIS-REx launched on September 8, 2016 from Cape Canaveral. It carries five data-taking instruments, and scientists hope to learn more about the Solar System’s origins and even what resources an asteroid might hold. The arrival marks the end of a two-year journey to Bennu, and the start of a 1.5-year study period.
~ We have only scratched the surface of the asteroid surface scratching. 

Curiosity Rover finds something really shiny — An unusually smooth and reflective Martian rock has caught the attention of NASA scientists, prompting an investigation by the Curiosity Rover. With the spectacularly successful landing of the InSight probe on Mars earlier this week, our attention has understandably been diverted away from Curiosity, which has been exploring the Red Planet since 2012.
~ Attack! Attack! No, wait … Profit! Profit!

Cancer test takes ten minutes — Scientists have developed a universal cancer test that can detect traces of the disease in a patient’s bloodstream. The cheap and simple test uses a colour-changing fluid to reveal the presence of malignant cells anywhere in the body and provides results in less than 10 minutes. The test has a sensitivity of about 90%, meaning it would detect about 90 in 100 cases of cancer.
~ And it came from the fact that DNA sticks to metal in different ways. 

Vaccine for bees — Bees may soon get an ally in their fight against bacterial disease — one of the most serious threats the pollinators face — in the form of an edible vaccine. That’s the promise held out by researchers in Finland, who say they’ve made the first-ever vaccine for insects, aimed at helping struggling honeybee populations.
~ Go bees! Go bees!

Plant motors to the light —  when a Pink Flamingo Peace Lily routed to a robotic planter on wheels detects light nearby, it signals the robot to move closer. Set between two desk lamps (which have a kinetic life of their own, thanks to the Pixar Animation Studios opening sequence starring Luxo), the researchers show how quickly the plant responds by switching them on and off again. As Sareen puts it, “The agency of such movements rests with the plant.”
~ No longer a secret agency. 

Repurposed coal mines could be the future of farming — Academics at the University of Nottingham see in them the potential future of food. They’ve patented a new system revolving around what they call “deep farming”: turning old coal mines into fully functioning farms.
Deep farms would have advantages that current land-based farms lack, including a controlled climate uninfluenced by weather and no need for expensive farming equipment. They wouldn’t need to be built in coal mines, but the scientists see them as a perfect starting point.
~ I think real progress will be made when we turn non-abandoned coal mines into underground farms. 

All new Californian homes to have solar panels — Solar panels will be a required feature on new houses in California, after the state’s Building Standards Commission gave final approval to a housing rule that’s the first of its kind in the United States. Set to take effect in 2020, the new standard includes an exemption for houses that are often shaded from the sun. It also includes incentives for people to add a high-capacity battery to their home’s electrical system, to store the sun’s energy.
~ Coz the sun always shines in California. 

Scientists gets more outrage for gene-edited twins — Ever since a Chinese scientist rocked the world by claiming he had created gene-edited twin girls, international outrage has only intensified. Francis Collins, director of the US National Institutes of Health called it a deeply unfortunate, misguided misadventure of the most dramatic sort. “It was shocking at the time. A week later, it’s still shocking.”
~ Well, that was frank, Francis. He will be chastised, no doubt.

Woman gives birth with transplanted uterus — A team of doctors in Brazil have announced a medical first that could someday help countless women unable to have children because of a damaged or absent uterus. In a case report published Tuesday in the Lancet, they claim to have successfully helped a woman give birth using a transplanted uterus from a deceased donor.
~ Thank goodness the donor was deceased. 

More ancient Black Death — Long before the two deadliest pandemics in history (the Plague of Justinian and the Black Plague) an ancient strain of the bacterium responsible for these scourges, Yersinia pestis, may have already wreaked havoc among Neolithic European communities over 5000 years ago, according to a controversial new study.
New research published in Cell describes a newly identified strain of Yersinia pestis, the bacterium that causes plague. The DNA of the new strain was extracted from a woman who lived in a Neolithic farming community about 4900 years ago in what is now Sweden.

Futurology ~ Pulsar nav, Magnetohydrodynamic Drive, air power, cancer test, snow Jandals, 3D printed drugs, NZ burrowing bat, iridescent dino


We used to think of dinosaurs in beige …

Pulsars to navigate space — Last week, Keith Gendreau and a team of NASA researchers announced they had finally proven that pulsars can function as a cosmic positioning system. Gendreau and his team performed the demonstration quietly last November, when the Neutron Star Interior Composition Explorer (a pulsar-measuring instrument the size of a washing machine, currently aboard the International Space Station) spent a weekend observing the electromagnetic emissions of five pulsars. With the help of an enhancement known as the Station Explorer for X-ray Timing and Navigation Technology (aka Sextant), Nicer was able to determine the station’s position in Earth’s orbit to within roughly three miles – while it was traveling in excess of 27,358kph (17,000mph).
~ Space is quite big, so not an unreasonable margin of error. 

The Magnetohydrodynamic Drive is real and you can build one — In the old movie The Hunt for Red October, the Russians built a so-called ‘caterpillar drive’ using hydro-magneto power instead of the traditional propeller. This new drive is way quieter than the traditional type, so quiet it could sneak up on the United States and blow it up. Here is the cool part: this magnetohydrodynamic drive, which turns water into a sort of rotor, is real. In fact, it’s pretty simple to build. All you really need is a battery, a magnet and some wires. Oh, also this will have to operate in salt water, so you might need some salt. Here is the basic setup.
~ Sure, the water gets pushed, but you can do it much better with a propeller.

Battery sucks power from the air — The Cota Forever Battery has the same size, form factor and power output of a traditional AA battery, but it can be inserted into a battery-powered device to instantly and easily make it compatible with Cota wireless power transmitters. Imagine never have to change the batteries in your TV remotes ever again, or not having to stay on top of countless IOT devices in your home that are constantly demanding a charge.
~ Yes, imagine all the strenuous effort this will save. An sucks power from the air? That’s how I’ve always thought about Coronation Street.

Blood test for cancer — The new test, developed at Johns Hopkins University, looks for signs of eight common types of cancer in just a blood sample and may prove inexpensive enough for doctors to give during a routine physical. Although the test isn’t commercially available yet, it will be used to screen 50,000 retirement-age women with no history of cancer as part of a $50 million, five-year study with the Geisinger Health System in Pennsylvania, a spokesperson with the insurer said.
~ Gadzooks, let’s hope it works. 

Snow Jandals — Snowshoes have been around for 5700 years, but this year Boulder, Colorado–based Crescent Moon has made the world’s first all-foam version (left – click it for a bigger view). Velcro bindings keep your shoes strapped to a teardrop-­shaped platform made from two layers of ethylene-vinyl acetate, or EVA, the same stuff used to fashion flip-flops. The snowshoes might look low-tech, but the combination of cleats and tire-like treads provide ample traction, especially on hardpack trails.
~ No more sinking feeling.  

3D print your own drugs — Someday soon, you might be making your own medicines at home. That’s because researchers have tailored a 3D printer to synthesize pharmaceuticals and other chemicals from simple, widely available starting compounds fed into a series of water bottle-size reactors. The work, they say, could digitize chemistry, allowing users to synthesize almost any compound anywhere in the world.
~ Yeah, can’t see any problems emerging from that. Grand plan. 

New Zealand’s burrowing bat — All but three land mammal species living on New Zealand were brought by modern humans, beginning around 800 years ago – and all three of those native mammal species are bats. But a newly discovered bat fossil suggests there may be more species hiding in the isle’s ancient rock. A team of researchers from Australia, New Zealand and the US announced that they have discovered evidence of an extinct bat species called Vulcanops jennyworthyae. The bat itself is weird: it was big and probably burrowed in the ground. But it also reveals a stranger evolutionary history of mammals on the island.
~ The 20 million-year-old bat teeth were pretty large, suggesting the bat was omnivorous and weighed around 40 grams.

English fossil palace — Turns out building blocks of Buckingham Palace (and a whole bunch of other buildings around the world) are made of 200 million year old microbes. Oolitic limestone is almost completely made of millimetre-sized spheres of carbonate called ooids, made from concentric layers of mineralised microbes.
~ Apt, since it houses fossilised royalty. 

Dino-bird had iridescent plumage — Caihong juji, a tiny, Jurassic-era dinosaur that lived 161 million years ago in what is now China was feathered theropod with an iridescent, rainbow coloured ring of feathers around its neck.
A nearly complete skeleton of Caihong juji – a name that means “rainbow with the big crest” in Mandarin – was discovered by a farmer in China’s Hebei Province in 2014. Researchers from the University of Texas at Austin and Shenyang Normal University have been taking a close look at it, releasing their findings in Nature Communications. Palaeontologist Dongyu Hu, the lead author of the new study, says the newly discovered dinosaur contained a curious mix of ancient and modern features, including iridescent plumage seen in some living ʻbirds.
~ But scientists speculating on what that plumage may have been for is wildly speculative, imo.
