Potential building block of lie life discovered in Titan’s atmosphere — Saturn’s moon Titan is a world of contrast; both eerily familiar and strikingly alien. Its calm seas and enormous sand dunes might remind you of Earth, until you learn that what’s flowing across Titan’s surface is not water, but liquid hydrocarbons. Titan’s nitrogen-rich atmosphere seems to have some of the ingredients for biology, but any life forms evolved to thrive at temperatures of -178°C would be practically unrecognisable.
~ What if they introduce themselves in a civil manner?
New theory suggest life wasn’t a fluke — Biophysicist Jeremy England made waves in 2013 with a new theory that cast the origin of life as an inevitable outcome of thermodynamics. His equations suggested that under certain conditions, groups of atoms will naturally restructure themselves so as to burn more and more energy, facilitating the incessant dispersal of energy and the rise of entropy or disorder in the universe. Now he’s testing his theory in computer simulations.
~ The rise of exceptional structures sure seems understandable.
Luxembourg passed space mining law — Last week Luxembourg’s parliament unanimously passed an asteroid mining law (which goes into effect Tuesday) that gives companies ownership of what they extract from the celestial bodies…
~ Well, if you can’t be a world power …
Gnarlier space junk — There’s plenty out there already, but thousands and thousands of satellites are set to launch to low-Earth orbit before 2025, adding greatly to the problem.
~ Smallsat revolution indeed …
Neutrino smacks into atom — In a study published last week in Science, Juan Collar’s group observed a new type of neutrino interaction: a neutrino bumping into an atomic nucleus, a process known as coherent elastic scattering.
~ An important matter.
330TB on a tiny tape cartridge — Sony developed a new type of tape that has a higher density of magnetic recording sites, and IBM Research worked on new heads and signal processing tech to actually read and extract data from those nanometre-long patches of magnetism. Sony’s new tape is underpinned by two novel technologies: an improved built-in lubricant layer, which keeps it running smoothly through the machine, and a new type of magnetic layer.
The new cartridges, when they’re eventually commercialised, will be significantly more expensive because of the tape’s complex manufacturing process.
~ ‘Data is king’, Sony sputters.
New microbe thanks to beer — In May 2014, a group of scientists took a field trip to a small brewery in an old warehouse in Seattle, Washington – and came away with a microbe scientists have never seen before. In so-called wild beer, the team identified a yeast belonging to the genus Pichia, which turned out to be a hybrid of a known species called P. membranifaciens and another Pichia species completely new to science. Other Pichia species are known to spoil a beer, but the new hybrid seems to smell better.
~ Well if I patented it, it would be microbe, but if you did: yorcrobe.
Australian electric highway — Australia is taking the electric car revolution one step further by announcing an A$4 million super-long electric highway, or a series of fast-charging electric vehicle stations. Queensland’s Electric Super Highway will be almost 2000 kilometres long, stretching from the Gold Coast on the state’s southern border to Cairns in the far north. 18 charging stations will span the highway, and all will allow vehicles charge in 30 minutes.
~ And there’s an entrepreneurial opportunity right there, as what will you do in the 30 minutes?
3D metal printing is about to go mainstream — Massachussetts company Desktop Metal is preparing to turn manufacturing on its head, with a 3D metal printing system that’s so much faster, safer and cheaper than existing systems that it’s going to compete with traditional mass manufacturing processes… Plenty of design studios and even home users run desktop printers, but the only affordable printing materials are cheap ABS plastics. And at the other end of the market, while organizations like NASA and Boeing are getting valuable use out of laser-melted metal printing, it’s a very slow and expensive process that doesn’t seem to scale well.
Desktop Metal is an engineering-driven startup whose founders include several MIT professors, and Emanuel Sachs, who has patents in 3D printing dating back to the dawn of the field in 1989.
Waste-gobling maggots — Aiming to reinvent the toilet, sanitation company The BioCycle is using black soldier maggots to convert waste into products like biodiesel. Meanwhile, EnviroFlightfeeds leftovers from brewing and ethanol production to larvae, whose poop makes a lovely food for prawns.
~ ‘Black soldier maggots’? Good lord!
Men to lose the most jobs to robots — They’re coming, in ever increasing numbers, for a certain kind of work. For farm and factory labor. For construction. For haulage. In other words, blue-collar jobs traditionally done by men.
~ Hobby time!
Companion robots — Kuri’s creators call it a “companion robot,” but this is no Furby. Kuri belongs to a new class of machines that actually are intelligent, and actually make useful assistants at home. They help disabled people with routine daily tasks, and soon they’ll remind the elderly to take their medication. Kuri’s more of an all-purpose companion, a member of your family that also happens to play music and take video.
Lake robot fights toxic algae bloom — The Environmental Sample Processor ESPniagara sits on the floor of Lake Erie’s western basin, where it collects algae from the surrounding water, analyzes microcystin (a small, circular liver-toxic protein), and uploads results for researchers at the end of every test.
Tardigrade still fascinates — You’re probably aware that nature’s most badass animal is undoubtedly the tiny tardigrade, or water bear. They might be small, but unlike your weak butt, they can live a life without water, withstand temperatures from -328 to 304 degrees Fahrenheit, and even survive the depths of space. How did evolution make such a strange creature, and who are its relatives?
~ But the name that sounds like something issued to me at high school.
Terrifying ocean predator changes the history of mass extinction — Two hundred and fifty-two million years ago, the Earth was in a really bad place. At the boundary of the Permian and Triassic periods, our biosphere experienced its most dramatic mass extinction event (so far), one so utterly complete that it has been solemnly termed the Great Dying. Precious little was spared, and it’s generally been thought that it took many millions of years for life to stand back up again. But a recently-discovered fossil dating to just after the Great Dying is helping to erode our vision of a slow post-extinction recovery, showing that ecosystems recovered very quickly, were thriving – and were full of teeth.
Rows upon rows of razor-edged teeth.
~ And you were wondering why our human antecedents left the oceans …
