Dear olivier hartmanshenn,

Here is your customized Science X Newsletter for week 31:

	Remains found in China may belong to third human lineage A team of paleontologists at the Chinese Academy of Sciences, working with colleagues from Xi'an Jiaotong University, the University of York, the University of Chinese Academy of Sciences and the National Research Center on Human Evolution, has found evidence of a previously unknown human lineage. In their study, reported in Journal of Human Evolution, the group analyzed the fossilized jawbone, partial skull and some leg bones of a hominin dated to 300,000 years ago.
	NASA hears signal from Voyager 2 spacecraft after mistakenly cutting contact After days of silence, NASA has heard from Voyager 2 in interstellar space billions of miles away.
	DNA study of remains at Delaware site find kinship among European settlers, African slaves Early colonial settlers likely survived the harsh frontier conditions of 17th-century Delaware because they banded as family units to work alongside enslaved African descendants and European indentured servants, according to a new study published this summer in Current Biology.
	NASA back in touch with Voyager 2 after 'interstellar shout' NASA has succeeded in re-establishing full contact with Voyager 2 by using its highest-power transmitter to send an "interstellar shout" that righted the distant probe's antenna orientation, the space agency said Friday.
	Scientists discover the highest-energy light coming from the sun Sometimes, the best place to hide a secret is in broad daylight. Just ask the sun.
	Viral room-temperature superconductor claims spark excitement—and skepticism Last week, a group of South Korean physicists made a startling claim. In two papers uploaded to the arXiv preprint server, they say they have created a material that "opens a new era for humankind."
	How many lottery tickets do you need to buy to guarantee a win? Mathematicians find the answer Mathematicians at The University of Manchester have answered the question: How many lottery tickets do you need to buy to guarantee wining something on the U.K. National Lottery?
	Indian lunar landing mission enters moon's orbit India's latest space mission entered the moon's orbit on Saturday ahead of the country's second attempted lunar landing, as its cut-price space program seeks to reach new heights.
	Collisions between asteroids may lead to formation of metal asteroids able to generate and record magnetism: Study Yale researchers may have solved a longstanding puzzle as to why certain metallic meteorites show traces of a magnetic field—a finding that may shed light on the formation of magnetic dynamos at the core of planets.
	NASA listens for Voyager 2 spacecraft after wrong command cuts contact NASA is listening for any peep from Voyager 2 after losing contact with the spacecraft billions of miles away.
	Arrowhead housed at Bern History Museum found to be made from meteoritic iron An international team of geologists and historians has found that an arrowhead housed at the Bern History Museum was made using meteoritic iron. In their paper published in Journal of Archaeological Science, the group describes the attributes of the arrowhead and where they believe the material it was made of came from.
	True shape of lithium revealed for the first time Rechargeable lithium-ion batteries power smartphones, electric vehicles and storage for solar and wind energy, among other technologies.
	Common blood thinner may double as cancer therapy Warfarin, a widely used blood thinner, appears to have potent anti-cancer properties, according to a study by Columbia University researchers. The study, conducted in human cells and in mice, found that warfarin stops tumors from interfering with a self-destruct mechanism that cells initiate when they detect mutations or other abnormalities.
	Study predicts black hole chirps occur in two universal frequency ranges They are mysterious, exciting and inescapable—black holes are some of the most exotic objects in the universe. With gravitational-wave detectors, it is possible to detect the chirp sound that two black holes produce when they merge, approximately 70 such chirps have been found so far.
	For the first time researchers restore feeling and lasting movement in man living with quadriplegia In a first-of-its-kind clinical trial, bioelectronic medicine researchers, engineers and surgeons at Northwell Health's The Feinstein Institutes for Medical Research have successfully implanted microchips into the brain of a man living with paralysis, and have developed artificial intelligence (AI) algorithms to re-link his brain to his body and spinal cord.
	Database with 2,400 prehistoric sites, a tool for human evolutionary studies Human history in one click: For the first time, numerous sites relating to the early history of mankind from 3 million to 20,000 years ago can be accessed in a large-scale database.
	New radar research overcomes nearly century-old trade-off between wavelength and distance resolution New interference radar functions employed by a team of researchers from Chapman University and other institutions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, construction, archaeology, mineralogy and many other domains of radar applications.
	Scientists discover unusual ultrafast motion in layered magnetic materials A common metal paper clip will stick to a magnet. Scientists classify such iron-containing materials as ferromagnets. A little over a century ago, physicists Albert Einstein and Wander de Haas reported a surprising effect with a ferromagnet. If you suspend an iron cylinder from a wire and expose it to a magnetic field, it will start rotating if you simply reverse the direction of the magnetic field.
	Jurassic era fish fossil found to have died from eating an overly large ammonite A pair of paleontologists at Universität Hohenheim's Staatliches Museum für Naturkunde Stuttgart has found a fossilized Jurassic-era fish that appears to have died after swallowing an overly large ammonite. Samuel Cooper and Erin Maxwell report their study of the fossil in the journal Geological Magazine.
	Single drop of ethanol to revolutionize nanosensor manufacture Macquarie University engineers have developed a new technique to make the manufacture of nanosensors far less carbon-intensive, much cheaper, more efficient, and more versatile, substantially improving a key process in this trillion-dollar global industry.
