Science X Newsletter Week 11

Dear Reader ,

Here is your customized Science X Newsletter for week 11:

	Physicists reverse time using quantum computer Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated the probability that an electron in empty interstellar space will spontaneously travel back into its recent past. The study is published in Scientific Reports.
	With single gene insertion, blind mice regain sight It was surprisingly simple. University of California, Berkeley, scientists inserted a gene for a green-light receptor into the eyes of blind mice and, a month later, they were navigating around obstacles as easily as mice with no vision problems. They were able to see motion, brightness changes over a thousandfold range and fine detail on an iPad sufficient to distinguish letters.
	Forgetting uses more brain power than remembering Choosing to forget something might take more mental effort than trying to remember it, researchers at The University of Texas at Austin discovered through neuroimaging.
	Scientists left camera traps to record wild apes—watch what happens Researchers analyzed video from remote camera-trap devices placed in ape-populated forests throughout Africa to see how wild apes would react to these unfamiliar objects. Responses varied by species and even among individuals within the same species, but one thing was consistent throughout: the apes definitely noticed the cameras—they poked them, stared at them, and occasionally tried to bite them. The study appears March 14 in the journal Current Biology.
	Dormant viruses activate during spaceflight Herpes viruses reactivate in more than half of crew aboard Space Shuttle and International Space Station missions, according to NASA research published in Frontiers in Microbiology. While only a small proportion develop symptoms, virus reactivation rates increase with spaceflight duration and could present a significant health risk on missions to Mars and beyond.
	Mammoth moves: frozen cells come to life, but only just A team of scientists in Japan has successfully coaxed activity from 28,000-year-old cells from a frozen mammoth implanted into mouse cells, but the woolly mammal is unlikely to be walking among us soon.
	Astronomers discover 83 supermassive black holes in the early universe Astronomers from Japan, Taiwan and Princeton University have discovered 83 quasars powered by supermassive black holes in the distant universe, from a time when the universe was less than 10 percent of its present age.
	Murdoch's News Corp calls for Google breakup Rupert Murdoch's News Corp has called for Google to be broken up in Australia, the latest salvo in a battle between the corporate media giants.
	Scientists one step closer to a clock that could replace GPS and Galileo Scientists in the Emergent Photonics Lab (EPic Lab) at the University of Sussex have made a breakthrough to a crucial element of an atomic clock—devices which could reduce our reliance on satellite mapping in the future—using cutting-edge laser beam technology. Their development greatly improves the efficiency of the lancet (which in a traditional clock is responsible for counting), by 80% - something which scientists around the world have been racing to achieve.
	Higher egg and cholesterol consumption hikes heart disease and death risk: study Cancel the cheese omelet. There is sobering news for egg lovers who have been happily gobbling up their favorite breakfast since the 2015-2020 Dietary Guidelines for Americans no longer limited how much dietary cholesterol or how many eggs they could eat.
	Tectonics in the tropics trigger Earth's ice ages, study finds Over the last 540 million years, the Earth has weathered three major ice ages—periods during which global temperatures plummeted, producing extensive ice sheets and glaciers that have stretched beyond the polar caps.
	ALMA observes the formation sites of solar-system-like planets Researchers have spotted the formation sites of planets around a young star resembling the sun. Two rings of dust around the star, at distances comparable to the asteroid belt and the orbit of Neptune in the solar system, suggest that we are witnessing the formation of a planetary system similar to our own.
	Researchers measure near-perfect performance in low-cost semiconductors Tiny, easy-to-produce particles, called quantum dots, may soon take the place of more expensive single crystal semiconductors in advanced electronics found in solar panels, camera sensors and medical imaging tools. Although quantum dots have begun to break into the consumer market—in the form of quantum dot TVs—they have been hampered by long-standing uncertainties about their quality. Now, a new measurement technique developed by researchers at Stanford University may finally dissolve those doubts.
	What scientists found after sifting through dust in the solar system Just as dust gathers in corners and along bookshelves in our homes, dust piles up in space too. But when the dust settles in the solar system, it's often in rings. Several dust rings circle the Sun. The rings trace the orbits of planets, whose gravity tugs dust into place around the Sun, as it drifts by on its way to the center of the solar system.
	An electronically tunable metasurface that rotates polarization Researchers at the University of Michigan and City University of New York have recently proposed and experimentally validated a transparent, electronically tunable metasurface. This metasurface, presented in a paper published in Physical Review X, can rotate the polarization of an arbitrarily polarized incident wave without changing its axial ratio.
	Geologic evidence supports theory that major cosmic impact event occurred approximately 12,800 years ago When UC Santa Barbara geology professor emeritus James Kennett and colleagues set out years ago to examine signs of a major cosmic impact that occurred toward the end of the Pleistocene epoch, little did they know just how far-reaching the projected climatic effect would be.
	Researchers confirm massive hyper-runaway star ejected from the Milky Way Disk A fast-moving star may have been ejected from the Milky Way's stellar disk by a cluster of young stars, according to researchers from the University of Michigan who say the star did not originate from the middle of the galaxy, as previously believed by astronomers.
	Astronomers investigate a recently reactivated radio magnetar A UK-German team of astronomers has conducted observations of a peculiar radio magnetar known as XTE J1810–197, which turned on in December 2018 after an almost decade-long period of quiescence. Results of these observations provide more information about the magnetar properties, and were presented in a paper published March 6 on arXiv.org.
	Wolves cooperate with humans Wolves lead, dogs follow—and both cooperate with humans. The statement is a bold one, especially as wolves have received a lot of negative attention in recent years. A recent study conducted by behavioural researchers at Vetmeduni Vienna, however, shows that dogs and wolves both work equally well with humans, albeit in different ways. The allegedly unequal brothers are thus much more similar than often assumed.
	Study uncovers genetic switches that control process of whole-body regeneration When it comes to regeneration, some animals are capable of amazing feats—if you cut the leg off a salamander, it will grow back. When threatened, some geckos drop their tails as a distraction, and regrow them later.
