Science X Newsletter Week 39

Dear Reader ,

Here is your customized Science X Newsletter for week 39:

	LIGO and Virgo observatories detect gravitational wave signals from black hole collision In August, detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. This discovery, announced today, is the first observation of gravitational waves by three different detectors, marking a new era of greater insights and improved localization of cosmic events now available through globally networked gravitational-wave observatories.
	Study links cancerous toxins to cannabis extract Researchers at Portland State University found benzene and other potentially cancer-causing chemicals in the vapor produced by butane hash oil, a cannabis extract.
	Driverless hover-taxi makes first 'concept' flight in Dubai Dubai has edged closer to its goal of launching a pioneering hover-taxi service, with the authorities announcing a successful "concept" flight was made on Monday without passengers.
	After 15 years in a vegetative state, nerve stimulation restores consciousness A 35-year-old man who had been in a vegetative state for 15 years after a car accident has shown signs of consciousness after neurosurgeons implanted a vagus nerve stimulator into his chest. The findings reported in Current Biology on September 25 show that vagus nerve stimulation (VNS)—a treatment already in use for epilepsy and depression—can help to restore consciousness even after many years in a vegetative state.
	New class of molecules may protect brain from stroke, neurodegenerative diseases Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health New Orleans, has discovered a new class of molecules in the brain that synchronize cell-to-cell communication and neuroinflammation/immune activity in response to injury or diseases. Elovanoids (ELVs) are bioactive chemical messengers made from omega-3 very long chain polyunsaturated fatty acids (VLC-PUFAs,n-3). They are released on demand when cells are damaged or stressed.
	Opinion: Vikings were never the pure-bred master race white supremacists like to portray The word "Viking" entered the Modern English language in 1807, at a time of growing nationalism and empire building. In the decades that followed, enduring stereotypes about Vikings developed, such as wearing horned helmets and belonging to a society where only men wielded high status.
	Russia, US shoot for the moon with joint lunar station project (Update) Russia and the United States agreed Wednesday to cooperate on a NASA-led project to build the first lunar space station, part of a long-term project to send humans to Mars.
	Modern humans emerged more than 300,000 years ago, new study suggests A genomic analysis of ancient human remains from KwaZulu-Natal revealed that southern Africa has an important role to play in writing the history of humankind. A research team from Uppsala University, Sweden, the Universities of Johannesburg and the Witwatersrand, South Africa, presents their results in the September 28th early online issue of Science.
	First open-access data from large collider confirm subatomic particle patterns In November of 2014, in a first, unexpected move for the field of particle physics, the Compact Muon Solenoid (CMS) experiment—one of the main detectors in the world's largest particle accelerator, the Large Hadron Collider—released to the public an immense amount of data, through a website called the CERN Open Data Portal.
	Large meteorite impacts drove plate-tectonic processes on the early Earth An international study led by researchers at Macquarie University has uncovered the ways in which giant meteorite impacts may have helped to kick-start our planet's global tectonic processes and magnetic field. The study, being published in the premier journal Nature Geoscience, explores the effect of meteorite bombardment, in geodynamic simulations of the early Earth.
	Gravitational twists help theoretical physicists shed light on quantum complexity Are we are living in a computer simulation? Intriguingly, the crux of this question may be hiding in an exotic quantum phenomenon which shows up in metals as a response to twists of space-time geometry.
	Researchers uncover the source of diabetic nerve pain A new King's College London study reveals the molecular basis of chronic nerve pain in diabetes. The findings in mice, published today in Science Translational Medicine, could one day lead to treatments which target the source of the pain.
	Researchers change wavelengths of entangled photons to those used in telecommunications The potential for photon entanglement in quantum computing and communications has been known for decades. One of the issues impeding its immediate application is the fact that many photon entanglement platforms do not operate within the range used by most forms of telecommunication.
	Move towards 'holy grail' of computing by creation of brain-like photonic microchips Scientists have made a crucial step towards unlocking the "holy grail" of computing - microchips that mimic the way the human brain works to store and process information.
	Moon village the first stop to Mars: ESA Setting up a permanent village on the moon is the first step towards exploring Mars, the European Space Agency said Thursday as plans to reach and colonise the Red Planet gathered pace.
	Unexpected surprise: A final image from Rosetta Scientists analysing the final telemetry sent by Rosetta immediately before it shut down on the surface of the comet last year have reconstructed one last image of its touchdown site.
	Hubble observes the farthest active inbound comet yet seen NASA's Hubble Space Telescope has photographed the farthest active inbound comet ever seen, at a whopping distance of 1.5 billion miles from the Sun (beyond Saturn's orbit). Slightly warmed by the remote Sun, it has already begun to develop an 80,000-mile-wide fuzzy cloud of dust, called a coma, enveloping a tiny, solid nucleus of frozen gas and dust. These observations represent the earliest signs of activity ever seen from a comet entering the solar system's planetary zone for the first time.
	Large solar storm sparks global aurora and doubles radiation levels on the martian surface An unexpectedly strong blast from the Sun hit Mars this month, observed by NASA missions in orbit and on the surface.
	Engineers create wristbands that keep wearers thermally comfortable Sitting in a stifling subway car or walking Boston's cold winter streets may soon become more bearable, thanks to a "personal thermostat" wristband being released by MIT spinout Embr Labs.
	IceCube helps demystify strange radio bursts from deep space For a decade, astronomers have puzzled over ephemeral but incredibly powerful radio bursts from space.
