Science X Newsletter Week 26

Dear Reader ,

Here is your customized Science X Newsletter for week 26:

	Groundbreaking discovery confirms existence of orbiting supermassive black holes For the first time ever, astronomers at The University of New Mexico say they've been able to observe and measure the orbital motion between two supermassive black holes hundreds of millions of light years from Earth - a discovery more than a decade in the making.
	Water exists as two different liquids We normally consider liquid water as disordered with the molecules rearranging on a short time scale around some average structure. Now, however, scientists at Stockholm University have discovered two phases of the liquid with large differences in structure and density. The results are based on experimental studies using X-rays, which are now published in Proceedings of the National Academy of Science (US).
	Japan reveals plans to put a man on moon by 2030 Japan has revealed ambitious plans to put an astronaut on the Moon around 2030 in new proposals from the country's space agency.
	Skull fragments with carved long, deliberate lines found at Gobekli Tepe (Phys.org)—A team of researchers with the German Archaeological Institute has found long, deliberate marks carved into ancient skulls found at the Göbekli Tepe dig site. In their paper published on the open access site Science Advances, the group describes the skull fragments they have been studying and offer some possible explanations for the markings they found.
	Hints of extra dimensions in gravitational waves? Researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam found that hidden dimensions – as predicted by string theory – could influence gravitational waves. In a recently published paper they study the consequences of extra dimensions on these ripples in space-time, and predict whether their effects could be detected.
	Collapse of the European ice sheet caused chaos Scientists have reconstructed in detail the collapse of the Eurasian ice sheet at the end of the last ice age. The big melt wreaked havoc across the European continent, driving home the original Brexit 10,000 years ago.
	The mere presence of your smartphone reduces brain power, study shows Your cognitive capacity is significantly reduced when your smartphone is within reach—even if it's off. That's the takeaway finding from a new study from the McCombs School of Business at The University of Texas at Austin.
	One billion suns: World's brightest laser sparks new behavior in light Physicists from the University of Nebraska-Lincoln are seeing an everyday phenomenon in a new light.
	Are asteroids humanity's 'greatest challenge'? Throughout its 4.5-billion-year history, Earth has been repeatedly pummelled by space rocks that have caused anything from an innocuous splash in the ocean to species annihilation.
	Study finds hackers could use brainwaves to steal passwords Researchers at the University of Alabama at Birmingham suggest that brainwave-sensing headsets, also known as EEG or electroencephalograph headsets, need better security after a study reveals hackers could guess a user's passwords by monitoring their brainwaves.
	Scientists find clever way to help you de-clutter your home If your attic is full of stuff you no longer use but can't bear to give away, a new study may offer you a simple solution.
	Electrocaloric refrigerator offers alternative way to cool everything from food to computers (Phys.org)—Researchers have built an electrocaloric refrigerator the size of a beverage coaster that can generate a temperature difference of about 2 K between the hot and cold ends of the device. The cooling mechanism, which is based on the electrocaloric effect, involves alternately applying and removing an electric field to a material to increase and decrease the material's temperature, respectively. The new cooling method can potentially achieve a higher efficiency than current methods, indicating that electrocaloric cooling devices may one day replace today's refrigerators and other cooling devices.
	Controlling a single brain chemical may help expand window for learning language and music Learning language or music is usually a breeze for children, but as even young adults know, that capacity declines dramatically with age. St. Jude Children's Research Hospital scientists have evidence from mice that restricting a key chemical messenger in the brain helps extend efficient auditory learning much later in life.
	Thwarting metastasis by breaking cancer's legs with gold rods "Your cancer has metastasized. I'm sorry," is something no one wants to hear a doctor say.
	Greenland now a major driver of rising seas: study Ocean levels rose 50 percent faster in 2014 than in 1993, with meltwater from the Greenland ice sheet now supplying 25 percent of total sea level increase compared with just five percent 20 years earlier, researchers reported Monday.
	No detectable limit to how long people can live: study Emma Morano passed away last April. At 117 years old, the Italian woman was the oldest known living human being.
	Tiny magnetic tremors unlock exotic superconductivity Deep within solids, individual electrons zip around on a nanoscale highway paved with atoms. For the most part, these electrons avoid one another, kept in separate lanes by their mutual repulsion. But vibrations in the atomic road can blur their lanes and sometimes allow the tiny particles to pair up. The result is smooth and lossless travel, and it's one way to create superconductivity.
	Sunscreen creams break down into dangerous chemical compounds under the sunlight Scientists from the Faculty of Chemistry of the Lomonosov Moscow State University have demonstrated in their research the nature of hazardous chemical compounds formed as a result of the breakdown of avobenzone, a component of many sunscreen products, when it interacts with chlorinated water and ultraviolet radiation. The chemists have presented the results in the Chemosphere journal.
	New measurement will help redefine international unit of mass Using a state-of-the-art device for measuring mass, researchers at the National Institute of Standards and Technology (NIST) have made their most precise determination yet of Planck's constant, an important value in science that will help to redefine the kilogram, the official unit of mass in the SI, or international system of units. Accepted for publication in the journal Metrologia, these new results come ahead of a July 1 international deadline for measurements that aim to redefine the entire SI in terms of fundamental constants of nature.
	Analysis of Neanderthal teeth grooves uncovers evidence of prehistoric dentistry Neanderthals treating toothaches?
