Science X Newsletter Week 38

Dear Reader ,

Here is your customized Science X Newsletter for week 38:

	Scientists confirm the universe has no direction The universe is not spinning or stretched in any particular direction, according to the most stringent test yet.
	China begins operating world's largest radio telescope The world's largest radio telescope began searching for signals from stars and galaxies and, perhaps, extraterrestrial life Sunday in a project demonstrating China's rising ambitions in space and its pursuit of international scientific prestige.
	Researchers discover a cell in spinach that uses sunlight to produce electricity and hydrogen Using a simple membrane extract from spinach leaves, researchers from the Technion-Israel Institute of Technology have developed a bio-photo-electro-chemical (BPEC) cell that produces electricity and hydrogen from water using sunlight. The raw material of the device is water, and its products are electric current, hydrogen and oxygen. The findings were published in the August 23 online issue of Nature Communications.
	Chemists find key to manufacturing more efficient solar cells In a discovery that could have profound implications for future energy policy, Columbia scientists have demonstrated it is possible to manufacture solar cells that are far more efficient than existing silicon energy cells by using a new kind of material, a development that could help reduce fossil fuel consumption.
	Towards quantum Internet: Researchers teleport particle of light six kilometres What if you could behave like the crew on the Starship Enterprise and teleport yourself home or anywhere else in the world? As a human, you're probably not going to realize this any time soon; if you're a photon, you might want to keep reading.
	NASA to reveal 'surprising' activity on Jupiter's moon Europa There's something going on beneath the surface of Jupiter's icy moon Europa. But what?
	Human DNA tied mostly to single exodus from Africa long ago (Update) A study of hundreds of new genomes from across the globe has yielded insights into modern genetic diversity and ancient population dynamics, including compelling evidence that essentially all non-Africans today descend from a single migration out of Africa.
	America's first wave-produced power goes online in Hawaii Off the coast of Hawaii, a tall buoy bobs and sways in the water, using the rise and fall of the waves to generate electricity.
	Smoking leaves lasting marks on DNA, study finds (HealthDay)—Smoking cigarettes can leave a lasting imprint on human DNA, altering more than 7,000 genes in ways that may contribute to the development of smoking-related diseases, a new study says.
	Researchers discover more efficient way to split water, produce hydrogen Hydrogen is often considered a fuel for the future, in the form of fuel cells to power electric motors or burned in internal combustion engines. But finding a practical, inexpensive and nontoxic way to produce large amounts of hydrogen gas – especially by splitting water into its component parts, hydrogen and oxygen – has been a challenge.
	Physicists retrieve 'lost' information from quantum measurements (Phys.org)—Typically when scientists make a measurement, they know exactly what kind of measurement they're making, and their purpose is to obtain a measurement outcome. But in an "unrecorded measurement," both the type of measurement and the measurement outcome are unknown.
	Coffee-infused foam removes lead from contaminated water Coffee is one of the most popular drinks in the U.S., which makes for a perky population—but it also creates a lot of used grounds. Scientists now report in the journal ACS Sustainable Chemistry & Engineering an innovative way to reduce this waste and help address another environmental problem. They have incorporated spent coffee grounds in a foam filter that can remove harmful lead and mercury from water.
	Acceleration relation found among spiral and irregular galaxies challenges current understanding of dark matter In the late 1970s, astronomers Vera Rubin and Albert Bosma independently found that spiral galaxies rotate at a nearly constant speed: the velocity of stars and gas inside a galaxy does not decrease with radius, as one would expect from Newton's laws and the distribution of visible matter, but remains approximately constant. Such 'flat rotation curves' are generally attributed to invisible, dark matter surrounding galaxies and providing additional gravitational attraction.
	A non-probabilistic quantum theory produces unpredictable results (Phys.org)—Quantum measurements are often inherently unpredictable, yet the usual way in which quantum theory accounts for unpredictability has long been viewed as somewhat unsatisfactory. In a new study, University of Oxford physicist Chiara Marletto has developed an alternative way to account for the unpredictability observed in quantum measurements by using the recently proposed theory of superinformation—a theory that is inherently non-probabilistic. The new perspective may lead to new possibilities in the search for a successor to quantum theory.
	Digitally unwrapped scroll reveals earliest Old Testament scripture (Update) An extremely fragile, ancient Hebrew scroll has been digitally unwrapped for the first time, revealing the earliest copy of Old Testament Bible scripture since the Dead Sea Scrolls, researchers said Wednesday.
	Research on stress hormone effects on the brain reveals unexpected findings Stress is a common problem often resulting in poor health and mental disorders. New research has revealed that current concepts on how stress hormones act on the brain may need to be reassessed.
	Nasa scientists find 'impossible' cloud on Titan—again The puzzling appearance of an ice cloud seemingly out of thin air has prompted NASA scientists to suggest that a different process than previously thought—possibly similar to one seen over Earth's poles—could be forming clouds on Saturn's moon Titan.
	Oxytocin enhances spirituality, new study says Oxytocin has been dubbed the "love hormone" for its role promoting social bonding, altruism and more. Now new research from Duke University suggests the hormone may also support spirituality.
	Scientists say ocean fossils found in mountains are cause for concern over future sea levels Tiny ocean fossils distributed widely across rock surfaces in the Transantarctic Mountains point to the potential for a substantial rise in global sea levels under conditions of continued global warming, according to a new study.
	Acoustic metamaterial panel absorbs low-frequency sound When it comes to low-frequency sound waves, traditional sound-absorbing materials tend to be undesirably bulky, heavy or thick.
