Upper class people more likely to cheat: study
The upper class has a higher propensity for unethical behavior, being more likely to believe – as did Gordon Gekko in the movie "Wall Street" – that "greed is good," according to a new study from the University of California, Berkeley.
Pasta-shaped radio waves beamed across Venice
A group of Italian and Swedish researchers appears to have solved the problem of radio congestion by cleverly twisting radio waves into the shape of fusilli pasta, allowing a potentially infinite number of channels to be broadcast and received.
Immortal worms defy aging
Researchers from The University of Nottingham have demonstrated how a species of flatworm overcomes the ageing process to be potentially immortal.
Your brain on 'shrooms: fMRI elucidates neural correlates of psilocybin psychedelic state
(Medical Xpress) -- Psychedelic substances have long been used for healing, ceremonial, or mind-altering subjective experiences due to compounds that, when ingested or inhaled, generate hallucinations, perceptual distortions, or altered states of awareness. Of these, the psychedelic substance psilocybin, the prodrug (a precursor of a drug that must in vivo chemical conversion by metabolic processes before becoming an active pharmacological agent) of psilocin (4-hydroxy-dimethyltryptamine) and the key hallucinogen found in so-called magic mushrooms, is widely used not only in healing ceremonies, but, more recently, in psychotherapy as well – but little has been known about its specific activity in the brain.
New picture of atomic nucleus emerges
(PhysOrg.com) -- When most of us think of an atom, we think of tiny electrons whizzing around a stationary, dense nucleus composed of protons and neutrons, collectively known as nucleons. A collaboration between the U.S. Department of Energy's Argonne and Thomas Jefferson National Laboratories has demonstrated just how different reality is from our simple picture, showing that a quarter of the nucleons in a dense nucleus exceed 25 percent of the speed of light, turning the picture of a static nucleus on its head.
Researchers develop 'SpeechJammer' gun that can quash human utterances
(PhysOrg.com) -- Imagine sitting around a conference table with several of your colleagues as you hold an important meeting. Now imagine your boss pulling out what looks like a radar gun for catching speeding motorists and aiming at any of you that speak to long, very nearly instantly causing whoever is speaking to start stuttering then mumbling and then to stop speaking at all. That’s the idea behind the SpeechJammer, a gun that can be fired at people to force them to stop speaking. It’s the brainchild of Koji Tsukada and Kazutaka Kurihara, science and technology researchers in Japan. They’ve published a paper describing how it works on the preprint server arXiv.
Dark matter core defies explanation
(PhysOrg.com) -- Astronomers using data from NASA's Hubble Telescope have observed what appears to be a clump of dark matter left behind from a wreck between massive clusters of galaxies. The result could challenge current theories about dark matter that predict galaxies should be anchored to the invisible substance even during the shock of a collision.
Tomb exploration reveals first archaeological evidence of Christianity from the time of Jesus
The archaeological examination by robotic camera of an intact first century tomb in Jerusalem has revealed a set of limestone Jewish ossuaries or "bone boxes" that are engraved with a rare Greek inscription and a unique iconographic image that the scholars involved identify as distinctly Christian.
Warp drives may come with a killer downside
Planning a little space travel to see some friends on Kepler 22b? Thinking of trying out your newly-installed FTL3000 Alcubierre Warp Drive to get you there in no time? Better not make it a surprise visit — your arrival may end up disintegrating anyone there when you show up.
Present ocean acidification rates are unprecedented: research
The world's oceans may be turning acidic faster today from human carbon emissions than they did during four major extinctions in the last 300 million years, when natural pulses of carbon sent global temperatures soaring, says a new study in Science. The study is the first of its kind to survey the geologic record for evidence of ocean acidification over this vast time period.
All-carbon-nanotube transistor can be crumpled like a piece of paper
(PhysOrg.com) -- Thanks to the flexible yet robust properties of carbon nanotubes, researchers have previously fabricated transistors that can be rolled, folded, and stretched. Now a team from Japan has made an all-carbon-nanotube transistor that can be crumpled like a piece of paper without degradation of its electrical properties. The new transistor is the most bendable reported to date that doesn’t experience a loss in performance.
With a bang, Navy begins tests on electromagnetic railgun prototype launcher
Engineers have fired the Navy's first industry-built electromagnetic railgun (EM Railgun) prototype launcher at a test facility, commencing an evaluation that is an important intermediate step toward a future tactical weapon for ships, officials announced Feb. 28.
European style stone tools suggest Stone Age people actually discovered America
(PhysOrg.com) -- Archeologists and historians have long known that it wasn’t really Christopher Columbus who discovered America. Native Americans had been living all over North, Central and South America long before he arrived. And Native Americans came from Asia across the frozen-over Bering Sea in the west. But now, it appears Europeans might have been first to arrive on the scene after all. Stone tools found recently in Delaware, Maryland and Virginia in the eastern United States, all appear to bear a striking resemblance to tools used by Stone Age peoples in early Europe, and have been dated to a time between 19,000 and 26,000 years ago, a period during which Stone Age people were making such tools, and long before the early Asians arrived.
IBM research advances device performance for quantum computing
(PhysOrg.com) -- Scientists at IBM Research have achieved major advances in quantum computing device performance that may accelerate the realization of a practical, full-scale quantum computer. For specific applications, quantum computing, which exploits the underlying quantum mechanical behavior of matter, has the potential to deliver computational power that is unrivaled by any supercomputer today.
Study finds thickest parts of Arctic ice cap melting faster
A new NASA study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean's floating ice cap.
Evidence suggests Neanderthals took to boats before modern humans
(PhysOrg.com) -- Neanderthals, considered either a sub-species of modern humans or a separate species altogether, lived from approximately 300,000 years ago to somewhere near 24,000 years ago, when they inexplicably disappeared, leaving behind traces of their DNA in some Middle Eastern people and artifacts strewn all across the southern part of Europe and extending into western Asia. Some of those artifacts, stone tools that are uniquely associated with them, have been found on islands in the Mediterranean Sea, suggesting, according to a paper published in the Journal of Archaeological Science, by George Ferentinos and colleagues, that Neanderthals had figured out how to travel by boat. And if they did, it appears they did so before modern humans.
Evolutionary question, answered
A new paper published in the Royal Society’s Biology Letters journal, shows that early experimental studies of the peppered moth, as taught to many American high school students, are “completely correct,” co-author James Mallet, Distinguished Lecturer on Organismic and Evolutionary Biology, said.
New measurements of W boson mass point to Higgs mass and test Standard Model
(PhysOrg.com) -- The world’s most precise measurement of the mass of the W boson, one of nature’s elementary particles, has been achieved by scientists from the CDF and DZero collaborations at the Department of Energy’s Fermi National Accelerator Laboratory. The new measurement is an important, independent constraint of the mass of the theorized Higgs boson. It also provides a rigorous test of the Standard Model that serves as the blueprint for our world, detailing the properties of the building blocks of matter and how they interact.
Samsung announces the Galaxy Beam Smartphone with built-in projector
(PhysOrg.com) -- Cell phones are great, but one of their limitations is the size of the screen, which of necessity has to be small. To get around this problem, engineers have been for years toying with the idea of building a projector into the phone so that images can be displayed on any nearby flat surface. Unfortunately, until now, such phones proved too bulky for users to accept. Now, however, Samsung appears to have jumped that hurdle as it announces the Galaxy Beam, a new, small, thin and lightweight phone that has a projector built into it that allows users to project whatever is on the screen onto any nearby surface.
Scientists image the charge distribution within a single molecule for the first time
(PhysOrg.com) -- IBM scientists were able to measure for the first time how charge is distributed within a single molecule. This achievement will enable fundamental scientific insights into single-molecule switching and bond formation between atoms and molecules. Furthermore, it introduces the possibility of imaging the charge distribution within functional molecular structures, which hold great promise for future applications such as solar photoconversion, energy storage, or molecular scale computing devices.
