Science X Newsletter Week 39

Dear Reader ,

Here is your customized Phys.org Newsletter for week 39:

	Antidepressants plus blood thinners cause brain cancer cells to eat themselves in mice Scientists have been exploring the connection between tricyclic antidepressants and brain cancer since the early 2000s. There's some evidence that the drugs can lower one's risk for developing aggressive glioblastomas, but when given to patients after diagnosis in a small clinical trial, the antidepressants showed no effect as a treatment.
	Toward tires that repair themselves A cut or torn tire usually means one thing—you have to buy a new one. But some day, that could change. For the first time, scientists have made tire-grade rubber without the processing step—vulcanization—that has been essential to inflatable tires since their invention. The resulting material heals itself and could potentially withstand the long-term pressures of driving. Their report appears in the journal ACS Applied Materials & Interfaces.
	New theory of stealth dark matter may explain universe's missing mass Lawrence Livermore scientists have come up with a new theory that may identify why dark matter has evaded direct detection in Earth-based experiments.
	Experiment confirms fundamental symmetry in nature Scientists working with ALICE (A Large Ion Collider Experiment), a heavy-ion detector on the Large Hadron Collider (LHC) ring, have made precise measurements of particle mass and electric charge that confirm the existence of a fundamental symmetry in nature. The investigators include Brazilian researchers affiliated with the University of São Paulo (USP) and the University of Campinas (UNICAMP).
	11-year cosmic search leads to black hole rethink One hundred years since Einstein proposed gravitational waves as part of his general theory of relativity, an 11-year search performed with CSIRO's Parkes telescope has failed to detect them, casting doubt on our understanding of galaxies and black holes.
	Tiny magnets mimic steam, water and ice Researchers at the Paul Scherrer Institute (PSI) created a synthetic material out of 1 billion tiny magnets. Astonishingly, it now appears that the magnetic properties of this so-called metamaterial change with the temperature, so that it can take on different states; just like water has a gaseous, liquid and a solid state. This material made of nanomagnets might well be refined for electronic applications of the future – such as for more efficient information transfer.
	A rechargeable battery to power a home from rooftop solar panels A team of Harvard scientists and engineers has demonstrated a rechargeable battery that could make storage of electricity from intermittent energy sources like solar and wind safe and cost-effective for both residential and commercial use. The new research builds on earlier work by members of the same team that could enable cheaper and more reliable electricity storage at the grid level.
	'Super blood moon' to give stargazers a rare show For the first time in decades, skygazers are in for the double spectacle Monday of a swollen "supermoon" bathed in the blood-red light of a total eclipse.
	Scientists discover new system for human genome editing A team including the scientist who first harnessed the revolutionary CRISPR-Cas9 system for mammalian genome editing has now identified a different CRISPR system with the potential for even simpler and more precise genome engineering.
	Study adds to evidence that viruses are alive A new analysis supports the hypothesis that viruses are living entities that share a long evolutionary history with cells, researchers report. The study offers the first reliable method for tracing viral evolution back to a time when neither viruses nor cells existed in the forms recognized today, the researchers say.
	Research pair offer a way to put a living organism into superposition state (Phys.org)—A pair of physicists, one with Tsinghua University in China, the other with Perdue University in the U.S. has come up with what they believe is a viable way to cause a living organism to be in two places at the same time. In the paper they have posted to the arXiv server, Zhang-Qi Yin and Tongcang Li suggest that an experiment conducted at the University of Colorado recently, could be modified by placing a living organism into a superposition state, rather than using just a piece of metal.
	Quantum entanglement: New study predicts a quantum Goldilocks effect Just as in the well-known children's story of Goldilocks and the Three Bears, something good happens when things are done in moderation, rather than in extremes.
	Perplexing new 'snakeskin' image of Pluto terrain from New Horizons The newest high-resolution images of Pluto from NASA's New Horizons are both dazzling and mystifying, revealing a multitude of previously unseen topographic and compositional details. The image below—showing an area near the line that separates day from night—captures a vast rippling landscape of strange, aligned linear ridges that has astonished New Horizons team members.
	Open-science van der Waals interaction calculations enable mesoscale design and assembly As molecular-level electronic, photonic and biological devices grow smaller, approaching the nanometer scale, chemists, physicists and materials scientists strive to predict the magnitude of the fundamental intermolecular interactions, and whether new hierarchical combinations of these material components will assemble and function as designed.
	Supermoon plus eclipse equals rare sky show Sunday night Get ready for a rare double feature, starring our very own moon.
	Spinning ring on a table found to behave more like a boomerang than a coin (Phys.org)—A trio of researchers, two with the University of California, the third with Sharif University of Technology, in Iran, has found that a common ring, such as is worn on the finger, spins differently on a tabletop than does a coin. In their paper published in Physical Review E, Mir Abbas Jalali, Milad Sarebangholi and Reza Alam describe their tests and observations and offer a theory on why a spinning ring behaves the way it does.
	'Golden' silver nanoparticle looks and behaves like gold (Phys.org)—In an act of "nano-alchemy," scientists have synthesized a silver (Ag) nanocluster that is virtually identical to a gold (Au) nanocluster. On the outside, the silver nanocluster has a golden yellow color, and on the inside, its chemical structure and properties also closely mimic those of its gold counterpart. The work shows that it may be possible to create silver nanoparticles that look and behave like gold despite underlying differences between the two elements, and could lead to creating similar analogues between other pairs of elements.
	Black hole is 30 times expected size The central supermassive black hole of a recently discovered galaxy is far larger than should be possible, according to current theories of galactic evolution. New work, carried out by astronomers at Keele University and the University of Central Lancashire, shows that the black hole is much more massive than it should be, compared to the mass of the galaxy around it. The scientists publish their results in a paper in Monthly Notices of the Royal Astronomical Society.
	Physicists break distance record for quantum teleportation Researchers at the National Institute of Standards and Technology (NIST) have "teleported" or transferred quantum information carried in light particles over 100 kilometers (km) of optical fiber, four times farther than the previous record.
	Ion space drive is said to break fuel efficiency record What's that? A space drive that reportedly wipes out NASA's fuel efficiency record? The news comes from Australia, from Neumann Space.
