Science X Newsletter Week 27

Dear Reader ,

Here is your customized Phys.org Newsletter for week 27:

	New model of cosmic stickiness favors 'Big Rip' demise of universe The universe can be a very sticky place, but just how sticky is a matter of debate.
	A social-network illusion that makes things appear more popular than they are A trio of researchers at the University of Southern California has uncovered a social-network illusion that might explain why some things become popular in cyberspace while others do not. Kristina Lerman, Xiaoran Yan and Xin-Zeng Wu have written a paper describing the illusion and how it works and have posted it on the preprint server arXiv.
	New method of quantum entanglement vastly increases how much information can be carried in a photon A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart they are —a phenomenon known as quantum entanglement.
	We're not alone—but the universe may be less crowded than we think There may be far fewer galaxies further out in the universe than might be expected, according to a new study led by Michigan State University.
	Quantum-dot spectrometer is small enough to function within a smartphone Instruments that measure the properties of light, known as spectrometers, are widely used in physical, chemical, and biological research. These devices are usually too large to be portable, but MIT scientists have now shown they can create spectrometers small enough to fit inside a smartphone camera, using tiny semiconductor nanoparticles called quantum dots.
	Snake skin inspired surfaces smash records, providing 40 percent friction reduction Snake skin inspired surfaces smash records, providing an astonishing 40% friction reduction in tests of high performance materials.
	System fixes bugs by importing functionality from other programs—without access to source code At the Association for Computing Machinery's Programming Language Design and Implementation conference this month, MIT researchers presented a new system that repairs dangerous software bugs by automatically importing functionality from other, more secure applications.
	'Map of life' predicts ET. (So where is he?) Extra-terrestrials that resemble humans should have evolved on other, Earth-like planets, making it increasingly paradoxical that we still appear to be alone in the universe, the author of a new study on convergent evolution has claimed.
	Astronomers predict fireworks from a close encounter of the stellar kind Astronomers are predicting a close encounter between a stellar remnant the size of a city and one of the brightest stars in the Milky Way.
	Single-celled predator evolves tiny, human-like 'eye' A single-celled marine plankton evolved a miniature version of a multi-cellular eye, possibly to help see its prey better, according to University of British Columbia (UBC) research published today in Nature.
	Soundproofing with quantum physics Sebastian Huber and his colleagues show that the road from abstract theory to practical applications needn't always be very long. Their mechanical implementation of a quantum mechanical phenomenon could soon be used for soundproofing purposes.
	Researchers discover new mechanism of DNA repair The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed.
	Solar plane lands in Hawaii after record-breaking flight (Update 2) A plane powered by the sun's rays landed in Hawaii Friday after a record-breaking five-day journey across the Pacific Ocean from Japan.
	Electric car is time-beater at Pikes Peak climb event For optimists enjoying the technology progress of electric cars, an encouraging turn of events took place recently with electric cars in the top two finishing spots at the Pikes Peak International Hill Climb (PPIHC) .
	Old World monkey had tiny, complex brain The brain hidden inside the oldest known Old World monkey skull has been visualized for the first time. The creature's tiny but remarkably wrinkled brain supports the idea that brain complexity can evolve before brain size in the primate family tree.
	First stars in the universe left a unique signature Determining the chemical abundance pattern left by the earliest stars in the universe is no easy feat. A Lawrence Livermore National Laboratory (LLNL) scientist is helping to do just that.
	A 'movie' of ultrafast rotating molecules at a hundred billion per second Can you imagine how subnano-scale molecules make an ultrafast rotation at a hundred billion per second? Do the ultrafast rotating subnano-scale molecules show a wave-like nature rather than particle-like behavior? The Japanese research team led by Professor Yasuhiro Ohshima at the Tokyo Institute of Technology, and Dr Kenta Mizuse at the Institute for Molecular Science, National Institutes of Natural Sciences, successfully took sequential "snapshots" of ultrafast unidirectionally rotating molecules at a hundred billion per second.
	Images in the air: Researchers turn to femtosecond lasers Say the word "display" and one easily anticipates an image on a screen or on a table surface or within a next-gen box enclosure. Last year, Aerial Burton went another route reminding everyone that something else is possible. The group demonstrated an aerial 3D display that projects text and images into mid-air.
	New nanogenerator harvests power from rolling tires A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car's rolling tire friction.
	Researchers develop algorithm to help identify patient zero in an epidemic (Phys.org)—A team of researchers affiliated with several institutions in Croatia has developed an algorithm that is able to help pinpoint the first person who became ill when an epidemic occurred. In their paper published in the journal Physical Review Letters, the team describes how they built their algorithm, how it was tested and how accurate they believe it is.
