Science X Newsletter Week 48

Dear Reader ,

Here is your customized Science X Newsletter for week 48:

	Anxiety abounds at NASA as Mars landing day arrives A NASA spacecraft's six-month journey to Mars neared its dramatic grand finale Monday in what scientists and engineers hoped would be a soft precision landing on flat red plains.
	Prehistoric cave art reveals ancient use of complex astronomy Some of the world's oldest cave paintings have revealed how ancient people had relatively advanced knowledge of astronomy.
	Google accused of manipulation to track users Seven European consumer groups filed complaints against Google with national regulators Tuesday, accusing the internet giant of covertly tracking users' movements in violation of an EU regulation on data protection.
	Endurance but not resistance training has anti-aging effects Researchers have discovered evidence that endurance exercise, such as running, swimming, cross-country skiing and cycling, will help you age better than resistance exercise, which involves strength training with weights.
	Study reveals how long it takes for LEGO head to pass through adult human digestive tract A team of researchers from several medical institutions in Australia and the U.K. has discovered how long it takes for a LEGO head to pass through the digestive tract of a normal healthy adult human. In their paper published in Journal of Paediatrics and Child Health, the group explains their reasons for conducting the research and what they found.
	New catalyst material produces abundant cheap hydrogen QUT chemistry researchers have discovered cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.
	Study suggests multiple instances of inter-breeding between Neanderthal and early humans A pair of researchers at Temple University has found evidence that suggests Neanderthals mated and produced offspring with anatomically modern humans multiple times—not just once, as has been suggested by prior research. In their paper published in the journal Nature Ecology and Evolution, Fernando Villanea and Joshua Schraiber describe their genetic analysis of East Asian and European people and how they compared to people from other places. Fabrizio Mafessoni with the Max Planck Institute for Evolutionary Anthropology offers a News and Views piece on the work done by the pair in the same journal issue.
	Antibiotics eliminate senescent cells associated with ageing Antibiotics have emerged as potentially lifespan-enhancing drugs, according to the results of new research carried out in the UK.
	Light triggers gold in unexpected way Rice University researchers have discovered a fundamentally different form of light-matter interaction in their experiments with gold nanoparticles.
	NASA's Martian quake sensor InSight lands at slight angle NASA's unmanned Martian quake sensor, InSight, has landed at a slight angle on the Red Planet, and experts are hopeful the spacecraft will work as planned, the US space agency said Friday.
	'Flawless': NASA craft lands on Mars after perilous journey A NASA spacecraft designed to drill down into Mars' interior landed on the planet Monday after a perilous, supersonic plunge through its red skies, setting off jubilation among scientists who had waited in white-knuckle suspense for confirmation to arrive across 100 million miles of space.
	Scientists decode mechanism of remembering—and forgetting It's a common expression to say that your brain is full. Although the brain doesn't literally fill up, in recent years researchers have discovered that the brain does sometimes push out old memories in order to take up new ones.
	InSight is catching rays on Mars NASA's InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface. NASA's Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 p.m. PST (8:30 p.m. EST). Solar array deployment ensures the spacecraft can recharge its batteries each day. Odyssey also relayed a pair of images showing InSight's landing site.
	Enormous dwarf satellite galaxy of Milky Way discovered Using data from ESA's Gaia spacecraft, astronomers have discovered a new Milky Way satellite in the constellation Antlia. The newly found dwarf galaxy, named Antlia 2, is several times larger when compared to other systems of similar luminosity. The finding is detailed in a paper published November 9 on arXiv.org.
	Scientists find a way to enhance the performance of quantum computers USC scientists have demonstrated a theoretical method to enhance the performance of quantum computers, an important step to scale a technology with potential to solve some of society's biggest challenges.
	Online sex ads rebound, months after shutdown of Backpage Smaller escort websites are vying for the lucrative online sex-for-hire market Backpage.com dominated before U.S. authorities shut it down earlier this year, a move that fractured the industry and forced law enforcement to adapt their efforts combating sex trafficking.
	Safely on Mars, InSight unfolds its arrays and snaps some pics After safely landing on Mars following its nearly seven month journey, NASA has released the first pictures taken by its InSight spacecraft, which has opened it solar arrays to charge batteries.
	Ancient DNA shows the Sámi and Finns share identical Siberian genes The first study on the DNA of the ancient inhabitants of Finland has been published, with results indicating that an abundance of genes reached Finland all the way from Siberia.
	Brilliant iron molecule could provide cheaper solar energy For the first time, researchers have succeeded in creating an iron molecule that can function both as a photocatalyst to produce fuel and in solar cells to produce electricity. The results indicate that the iron molecule could replace the more expensive and rarer metals used today.
	A new way to provide cooling without power MIT researchers have devised a new way of providing cooling on a hot sunny day, using inexpensive materials and requiring no fossil fuel-generated power. The passive system, which could be used to supplement other cooling systems to preserve food and medications in hot, off-grid locations, is essentially a high-tech version of a parasol.
