Science X Newsletter Week 37

Dear Reader ,

Here is your customized Phys.org Newsletter for week 37:

	Frankenvirus emerges from Siberia's frozen wasteland Scientists said they will reanimate a 30,000-year-old giant virus unearthed in the frozen wastelands of Siberia, and warned climate change may awaken dangerous microscopic pathogens.
	Surprising giant ring-like structure in the universe (Phys.org)—Five billion light years is a distance almost inconceivable, even on a cosmic scale. To better illustrate the extent of this physical quantity, it's enough to say that 35,000 galaxies the size of our Milky Way are needed to cover that distance. Thanks to a surprising discovery made by a Hungarian-U.S. team of astronomers, now we know that a structure this big really exists in the observable universe.
	Scientists discover cause of and potential treatment for muscle weakness and loss due to aging As we grow older, we lose strength and muscle mass. However, the cause of age-related muscle weakness and atrophy has remained a mystery.
	Oldest fossil sea turtle discovered Scientists at the Senckenberg Research Institute in Frankfurt have described the world's oldest fossil sea turtle known to date. The fossilized reptile is at least 120 million years old – which makes it about 25 million years older than the previously known oldest specimen. The almost completely preserved skeleton from the Cretaceous, with a length of nearly 2 meters, shows all of the characteristic traits of modern marine turtles. The study was published today in the scientific journal PaleoBios.
	Ceres' bright spots seen in striking new detail The brightest spots on the dwarf planet Ceres gleam with mystery in new views delivered by NASA's Dawn spacecraft. These closest-yet views of Occator crater, with a resolution of 450 feet (140 meters) per pixel, give scientists a deeper perspective on these very unusual features.
	Scientists produce cancer drug from rare plant in lab Many of the drugs we take today to treat pain, fight cancer or thwart disease were originally identified in plants, some of which are endangered or hard to grow. In many cases, those plants are still the primary source of the drug.
	Hummingbirds find protection building nests under hawks (Phys.org)—An international team of researchers working in a part of Arizona has found evidence of a hummingbird species benefiting by building nests in trees beneath hawk hunting grounds. In their paper published in the journal Science Advances, the team describes the study they carried out and just how much safer the hummingbirds appeared to be when living in close proximity to hawks.
	Entanglement lifetime extended orders of magnitude using coupled cavities (Phys.org)—Entangled qubits form the basic building blocks of quantum computers and other quantum technologies, but when qubits lose their entanglement, they lose their quantum advantage over classical bits. Unfortunately, entanglement decays very quickly due to unavoidable interactions with the surrounding environment, so preserving entanglement for long enough to use it has been a key challenge for realizing quantum technologies.
	Scientists create world's largest protein map to reveal which proteins work together in a cell A multinational team of scientists have sifted through cells of vastly different organisms, from amoebae to worms to mice to humans, to reveal how proteins fit together to build different cells and bodies.
	Research team demonstrates LEDs that use visible light to talk to each other and internet The light that typically floods homes, offices and public buildings could provide something more than illumination. Scientists at Disney Research and ETH Zurich have demonstrated that light could be a medium for light bulbs to communicate - with each other, with objects and with the Internet.
	Russian cosmonaut back after record 879 days in space Russian cosmonaut Gennady Padalka returned safely to Earth with two other astronauts from the International Space Station Saturday with the record for having spent the most time in space.
	Researchers use laser to levitate, glowing nanodiamonds in vacuum Researchers have, for the first time, levitated individual nanodiamonds in vacuum. The research team is led by Nick Vamivakas at the University of Rochester who thinks their work will make extremely sensitive instruments for sensing tiny forces and torques possible, as well as a way to physically create larger-scale quantum systems known as macroscopic Schrödinger Cat states.
	More efficient memory-management scheme could help enable chips with thousands of cores In a modern, multicore chip, every core—or processor—has its own small memory cache, where it stores frequently used data. But the chip also has a larger, shared cache, which all the cores can access.
	Burning remaining fossil fuel could cause 60-meter sea level rise New work from an international team including Carnegie's Ken Caldeira demonstrates that the planet's remaining fossil fuel resources would be sufficient to melt nearly all of Antarctica if burned, leading to a 50- or 60-meter (160 to 200 foot) rise in sea level. Because so many major cities are at or near sea level, this would put many highly populated areas where more than a billion people live under water, including New York City and Washington, DC. It is published in Science Advances.
	Implant captures cancer cells Scientists in the United States said Tuesday they had created a tiny implant which, in mice for now, captures cancer cells spreading through the body.
	Mysterious, massive, magnetic stars A Canadian PhD student has discovered a unique object – two massive stars with magnetic fields in a binary system. Matt Shultz of Queen's University, Ontario, Canada found the system – Epsilon Lupi – and will publish the new result in Monthly Notices of the Royal Astronomical Society.
	Mars panorama from Curiosity shows petrified sand dunes Some of the dark sandstone in an area being explored by NASA's Curiosity Mars rover shows texture and inclined bedding structures characteristic of deposits that formed as sand dunes, then were cemented into rock.
	Study: Bones in South African cave reveal new human relative Scientists say they've discovered a new member of the human family tree, revealed by a huge trove of bones in a barely accessible, pitch-dark chamber of a cave in South Africa.
	Team announces breakthrough observation of Mott transition in a superconductor An international team of researchers, including the MESA+ Institute for Nanotechnology at the University of Twente in The Netherlands and the U.S. Department of Energy's Argonne National Laboratory, announced today in Science the observation of a dynamic Mott transition in a superconductor.
	Facebook data suggests people from higher social class have fewer international friends A new study conducted in collaboration with Facebook using anonymised data from the social networking site shows a correlation between people's social and financial status, and the levels of internationalism in their friendship networks - with those from higher social classes around the world having fewer friends outside of their own country.
