Dear Joash Mabs,
Here is your customized PHYSorg.com Newsletter for week 20:
Quantum teleportation achieved over 16 km
(PhysOrg.com) -- Scientists in China have succeeded in teleporting information between photons further than ever before. They transported quantum information over a free space distance of 16 km (10 miles), much further than the few hundred meters previously achieved, which brings us closer to transmitting information over long distances without the need for a traditional signal.
Scientists find evidence for significant matter-antimatter asymmetry
(PhysOrg.com) -- Scientists of the DZero collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced Friday, May 14, that they have found evidence for significant violation of matter-antimatter symmetry in the behavior of particles containing bottom quarks beyond what is expected in the current theory, the Standard Model of particle physics.
Physicists prove Einstein wrong with observation of instantaneous velocity in Brownian particles
A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicist Mark Raizen and his group have done so.
First 'synthetic life': Scientists 'boot up' a bacterial cell with a synthetic genome
(PhysOrg.com) -- Scientists have developed the first cell controlled by a synthetic genome. They now hope to use this method to probe the basic machinery of life and to engineer bacteria specially designed to solve environmental or energy problems.
Mathematical model explains marital breakups
(PhysOrg.com) -- Most people know love takes work, and effort is needed to sustain a happy relationship over the long term, but now a mathematician in Spain has for the first time explained it mathematically by developing a dynamical mathematical model based on the second law of thermodynamics to model "sentimental dynamics." The results are consistent with sociological data on marriage breakdowns.
Explained: The Carnot Limit
Anytime engineers try to design a new kind of heat-based engine or improve on an existing design, they bump up against a fundamental efficiency limit: the Carnot Limit.
Gravity might amplify quantum fluctuations, create astrophysical objects
(PhysOrg.com) -- In a new study, physicists have proposed that gravity could trigger a runaway effect in quantum fluctuations, causing them to grow so large that the quantum field's vacuum energy density could dominate its classical energy density. This vacuum-dominance effect, which emerges under some specific but reasonable conditions, contrasts with the widely held belief that the influence of gravity on quantum phenomena should be small and subdominant.
Paper supercapacitor could power future paper electronics
(PhysOrg.com) -- All those paper transistors and paper displays that scientists have been designing can now be powered by an onboard power source, thanks to the development of a new paper supercapacitor. Designed by researchers at Stanford University, the paper supercapacitor is made by simply printing carbon nanotubes onto a treated piece of paper. The researchers hope that the integrated design could lead to the development of low-cost, disposable paper electronics.
Hubble Finds Star Eating a Planet
(PhysOrg.com) -- The hottest known planet in the Milky Way galaxy may also be its shortest-lived world. The doomed planet is being eaten by its parent star, according to observations made by a new instrument on NASA's Hubble Space Telescope, the Cosmic Origins Spectrograph (COS). The planet may only have another 10 million years left before it is completely devoured.
Engineers Diagnosing Voyager 2 Data System (Update)
(PhysOrg.com) -- One flip of a bit in the memory of an onboard computer appears to have caused the change in the science data pattern returning from Voyager 2, engineers at NASA's Jet Propulsion Laboratory said Monday, May 17. A value in a single memory location was changed from a 0 to a 1.
New method to make gallium arsenide solar cells
(PhysOrg.com) -- A new "transfer-printing" method of making light-sensitive semiconductors could make solar cells, night-vision cameras, and a range of other devices much more efficient, and could transform the solar industry.
Professor examines the complex evolution of human morality
(PhysOrg.com) -- Although the question of what makes humans different from other animals doesn't have a single obvious answer, one seemingly conspicuous human trait is morality. Darwin, in his book The Descent of Man, and Selection in Relation to Sex, published in 1871, singled out "the moral sense or conscience" as by far the most important difference between humans and other animals. Darwin's argument was, of course, strongly based on the concepts of biological evolution and natural selection. Now, upon further investigating the origins of morality, Francisco Ayala, a professor of ecology and evolutionary biology at the University of California, Irvine, has proposed a Darwin-inspired explanation of how human morality might have evolved.
Greenland rapidly rising as ice melt continues
Greenland is situated in the Atlantic Ocean to the northeast of Canada. It has stunning fjords on its rocky coast formed by moving glaciers, and a dense icecap up to 2 km thick that covers much of the island--pressing down the land beneath and lowering its elevation. Now, scientists at the University of Miami say Greenland's ice is melting so quickly that the land underneath is rising at an accelerated pace.
YeZ: The Car that Acts Like a Plant
(PhysOrg.com) -- What if there was an eco-friendly car that acted like a plant? It would take in CO2, and its exhaust would be oxygen. That's exactly what the Shanghai Automotive Industry Corporation unveiled at the Shanghai Expo 2010 recently. The YeZ is a concept car designed to photosynthesize carbon dioxide from the air, much like a plant. The car is even designed to emphasize the idea of a eco-friendly through a plant-like process.
'Impossible' conductivity explained
(PhysOrg.com) -- Bring two materials that are not themselves conductive into contact and, exactly at their interface, something remarkable happens: at that precise point, conduction is possible.
Plasmonic Promises: First Observation of Plasmarons in Graphene
(PhysOrg.com) -- The energy bands of complex particles known as plasmarons have been seen for the first time by scientists working with graphene at the Advanced Light Source. Their discovery may hasten the day when these crystalline sheets of carbon just one atom thick can be used to build ultrafast computers and other electronic, photonic, and plasmonic devices on the nanoscale.
Nanotech discovery could lead to breakthrough in infrared satellite imaging technology
Researchers from Rensselaer Polytechnic Institute have developed a new nanotechnology-based "microlens" that uses gold to boost the strength of infrared imaging and could lead to a new generation of ultra-powerful satellite cameras and night-vision devices.
Unique eclipsing binary star system discovered
(PhysOrg.com) -- Astrophysicists at UC Santa Barbara are the first scientists to identify two white dwarf stars in an eclipsing binary system, allowing for the first direct radius measurement of a rare white dwarf composed of pure helium. The results will be published in the Astrophysical Journal Letters. These observations are the first to confirm a theory about a certain type of white dwarf star.
Machines that learn better
(PhysOrg.com) -- In the last 20 years or so, many of the key advances in artificial-intelligence research have come courtesy of machine learning, in which computers learn how to make predictions by looking for patterns in large collections of training data. A new approach called probabilistic programming makes it much easier to build machine-learning systems, but it's useful for a relatively narrow set of problems. Now, MIT researchers have discovered how to extend the approach to a much larger class of problems, with implications for subjects as diverse as cognitive science, financial analysis and epidemiology.
Oceans Smaller And Warmer
Two new studies out this week give the best scientific estimates of the average depth of the world's oceans, the total amount of water they contain, and the extent to which this water warmed over the last two decades - the latter being an important measure of climate change.
