Phys.Org Newsletter Week 49

Dear Reader ,

Here is your customized Phys.org Newsletter for week 49:

Humans not smarter than animals, just different, experts say
(Phys.org) �Humans have been deceiving themselves for thousands of years that they're smarter than the rest of the animal kingdom, despite growing evidence to the contrary, according to University of Adelaide experts in evolutionary biology.

Creation of entanglement simultaneously gives rise to a wormhole
Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics�so strange, in fact, that Albert Einstein famously referred to it as "spooky action at a distance."

Study reveals striking differences in brain connectivity between men and women
A new brain connectivity study from Penn Medicine published today in the Proceedings of National Academy of Sciences found striking differences in the neural wiring of men and women that's lending credence to some commonly-held beliefs about their behavior.

Scientists build a low-cost, open-source 3-D metal printer
OK, so maybe you aren't interested in making your own toys, cellphone cases, or glow-in-the-dark Christmas decorations. How about a brake drum?

New superconductor theory may revolutionize electrical engineering
(Phys.org) �High-temperature superconductors exhibit a frustratingly varied catalog of odd behavior, such as electrons that arrange themselves into stripes or refuse to arrange themselves symmetrically around atoms. Now two physicists propose that such behaviors � and superconductivity itself � can all be traced to a single starting point, and they explain why there are so many variations.

Astronomers discover planet that shouldn't be there
An international team of astronomers, led by a University of Arizona graduate student, has discovered the most distantly orbiting planet found to date around a single, sun-like star. It is the first exoplanet � a planet outside of our solar system � discovered at the UA.

'Spooky action' builds a wormhole between 'entangled' quantum particles
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as "spooky action at a distance," could be even spookier than Einstein perceived.

Masturbation actually has health�benefits
Conduct an Internet search for "masturbation," and you will find hundreds, if not thousands, of slang phrases for the act.

Mathematical scientist suggests possible test for existence of axions
(Phys.org) �A mathematical scientist with the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge, has proposed a possible way to test for the existence of axions�theoretical particles that might be possible components of dark matter. In his paper published in Physical Review Letters, Christian Beck suggests it might be possible to detect the existence of axions by using a Josephson junction.

New highly efficient thermoelectronic generator
Through a process known as thermionic conversion, heat energy�such as light from the sun or heat from burned fossil fuels�can be converted into electricity with very high efficiency. Because of its promise, researchers have been trying for more than half a century to develop a practical thermionic generator, with little luck. That luck may soon change, thanks to a new design�dubbed a thermoelectronic generator�described in AIP Publishing's Journal of Renewable and Sustainable Energy (JRSE).

Coffee or beer? The choice could affect your genome
Coffee and beer are polar opposites in the beverage world. Coffee picks you up, and beer winds you down.

Time warp: Researchers show possibility of cloning quantum information from the past
(Phys.org) �Popular television shows such as "Doctor Who" have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU's Mark Wilde has shown that it would theoretically be possible for time travelers to copy quantum data from the past.

Oldest hominin DNA sequenced
Using novel techniques to extract and study ancient DNA researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have determined an almost complete mitochondrial genome sequence of a 400,000-year-old representative of the genus Homo from Sima de los Huesos, a unique cave site in Northern Spain, and found that it is related to the mitochondrial genome of Denisovans, extinct relatives of Neandertals in Asia. DNA this old has until recently been retrieved only from the permafrost.

Cassini spacecraft obtains best views of Saturn hexagon
(Phys.org) �NASA's Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn's north pole.

Human ancestor was less-chimp-like than thought: study
The last common ancestor of Man and Ape was not a knuckle-walking, tree-swinging hominid resembling today's chimpanzee, said a study Tuesday challenging some long-held theories of human evolution.

Gene therapy scores big wins against blood cancers
In one of the biggest advances against leukemia and other blood cancers in many years, doctors are reporting unprecedented success by using gene therapy to transform patients' blood cells into soldiers that seek and destroy cancer.

Startup rolls out earlybird offer for Copenhagen Wheel (w/ Video)
Superpedestrian, a Cambridge-based start-up, started making the Copenhagen Wheel available for preorders on Tuesday. According to the company, shipping begins spring 2014. For those following the development of the Copenhagen Wheel, this is news, as the wheel, which is designed to turn ordinary bicycles into smart electric hybrids, first made its debut in 2009 at the UN Climate Change Conference. A key feature of the device is that it can compensate with additional power whenever needed. Riding with the Copenhagen Wheel in place, the user can capture the energy dissipated while braking and cycling and save it for times when a boost is needed.

Ten times more throughput on optic fibers
Optical fibers carry data in the form of pulses of light over distances of thousands of miles at amazing speeds. They are one of the glories of modern telecommunications technology. However, their capacity is limited, because the pulses of light need to be lined up one after the other in the fiber with a minimum distance between them so the signals don't interfere with each other. This leaves unused empty space for data in the fiber.

Climate change 'tipping points' imminent
(Phys.org) �UC Berkeley's Tony Barnosky joined climate scientists this morning at a press conference at the National Academy of Sciences in Washington, D.C., to summarize a new report issued today focusing on the short-term effects of climate change and the need to monitor them closely.

Composite battery boost
(Phys.org) �New composite materials based on selenium (Se) sulfides that act as the positive electrode in a rechargeable lithium-ion (Li-ion) battery could boost the range of electric vehicles by up to five times, according to groundbreaking research carried out at the U.S. Department of Energy's Advanced Photon Source at Argonne National Laboratory. The studies of the materials demonstrated that they have the potential to pack five times the energy density of conventional batteries.
