All Disk Galaxies rotate once every billion years — According to a new study published in The Monthly Notices of the Royal Astronomical Society, astronomers discovered that all disk galaxies rotate about once every billion years, no matter their size or mass.
~ Is it just me who finds it weird that distant galaxies follow a time frame dictated by the sun we happen to be circling?
Kepler space telescope is running out of gas — NASA’s Kepler spacecraft has been peering deep into the Milky Way galaxy for nearly a decade. It has spotted over 2500 confirmed planets orbiting distant stars, with another 2500-plus possible worlds are waiting to be confirmed. But Kepler will be out of fuel in just a few months and left to its long, lonely orbit. The spacecraft will soon be replaced by another exoplanet-hunting space telescope, NASA’s Transiting Exoplanet Survey Satellite (TESS). TESS is set to launch into space on April 16th.
~ Er, they didn’t fit solar panels??
Gravitational Wave Detector progress — One of the most expensive, complex and problematic components in gravitational wave detectors like the Laser Interferometer Gravitational-wave Observatory (LIGO) — which made the first, historic detection of these ripples in space-time in September 2015 — is the 4-kilometer-long vacuum chambers that house all the interferometer optics. But what if this requirement for ground-based gravitational wave detectors isn’t needed? This suggestion has been made by a pair of physicists at the University of Maryland, Baltimore County (UMBC). They are developing a method that could allow extremely sensitive interferometers to operate in the “open air.”
~ After all, the open air is good for nearly everyone.
Devices get smaller, so which watch? Can you imagine that one day all your devices might be in that thing around your wrist? Already, some people use smartphones alone for all their computing … inconceivable 10 years ago. Reviews.com has decided on what’s best so far.
Ghostly beetle for new white — Scientists have engineered perhaps the whitest natural substance, using the same physics behind one ghostly white Southeast Asian beetle. White and black feel like opposites for a reason. Black-coloured things absorb nearly all of the light that strikes their surface, while white things send the light back, scattered equally at all wavelengths. A team of European scientists have essentially created the whitest paper using this physical property.
~ It can be 20 to 30 times whiter than white filter paper. Ouch!
Amputees to get new limb ‘feeling’ — Prosthetic hands have gotten increasingly sophisticated. Many can recreate the complex shape and detail of joints and fingers, while powered prostheses allow for independent, willful movement. But a new study published in Science Translational Medicine offers a potential glimpse into the future of the technology: Artificial hands that actually feel like living limbs as they move.
New methods find undiagnosed genetic diseases in electronic health records — Researchers have found a way to search genetic data in electronic health records to identify undiagnosed genetic diseases in large populations so treatments can be tailored to the actual cause of the illness.
~ Yay, a use for Big Data that’s other than pecuniary.
New brain preservation technique could lead to mind uploading — Using a technique developed three years ago, researchers from MIT and 21st Century Medicine have shown that it’s possible to preserve the microscopic structures contained within a large mammalian brain. The breakthrough means scientists now have the means to store and study samples of the human brain over longer timescales – but the method could eventually, maybe, be used to resurrect the dead.
~ It’s the downloading part some people clearly need.
Nanoparticle eyedrops may one day replace glasses — A new paper from Bar-Ilan University’s Institute of Nanotechnology and Advances Materials in Tel Aviv, Israel and published by the European Society of Cataract & Refractive Surgeons, outlines the research, which involves a combination of “nanodrops” and a quick medical procedure.
~ But how will you wipe those smears off them?
Systemic weirdness — The universe is loaded with a lot of strange symmetries between seemingly dissimilar systems, thanks to similar underlying physics. Take an electrical circuit, a spring and a swinging pendulum. These simple oscillators might look completely different, but they are governed by the same mathematical equations. Other similarities aren’t so simple – which makes them especially mind-boggling.
Separate teams of researchers have announced another discovery: specially-engineered materials, called topological insulators, displaying similar behaviours in very different systems.
~ I don’t think that’s weird. It’s like two vastly different political systems ending up with the same result: one was called Hitler and the other, Stalin.
Particle accelerator reveals hidden text — History and particle physics seem like pretty disparate fields but they have more in common than you’d think. X-rays from a high-energy lab have revealed ancient Greek medical texts that had been stripped and covered with religious writing.
Scientists at the Department of Energy’s SLAC National Accelerator Laboratory have long been using high-powered X-rays at their Stanford Synchrotron Radiation Lightsource (SSRL) to analyse ancient texts. This week, they will be revealing the text beneath 10th-century psalms from the St Catherine’s Monastery on the Sinai Peninsula. The hidden words were a translation of writings by the ancient Greek doctor Galen.
~ Wasn’t he in Planet of the Apes? And yes, there is a connection there, too.
Modern humans interbred with Denisovans twice in history — Modern humans co-existed and interbred with Neanderthals, sure, but also with another species of archaic humans, the mysterious Denisovans. Research now describes how, while developing a new genome-analysis method for comparing whole genomes between modern human and Denisovan populations, researchers unexpectedly discovered two distinct episodes of Denisovan genetic intermixing, or admixing, between the two.
~ Let’s all hope it was consensual.
Entomologist confirms first Saharan farming 10,000 years ago — By analysing a prehistoric site in the Libyan desert, a team of researchers has been able to establish that people in Saharan Africa were cultivating and storing wild cereals 10,000 years ago. In addition to revelations about early agricultural practices, there could be a lesson for the future, if global warming leads to a necessity for alternative crops.
~ But first they had to rule out ants.
