A 40-year-old puzzle of superstring theory solved by supercomputer
A group of three researchers from KEK, Shizuoka University and Osaka University has for the first time revealed the way our universe was born with 3 spatial dimensions from 10-dimensional superstring theory in which spacetime has 9 spatial directions and 1 temporal direction. This result was obtained by numerical simulation on a supercomputer.
Mystery predators may have contributed to fiscal collapse in 2007: research
(PhysOrg.com) -- As the nation bristles, camps out, and opines against the destructive role of banks in bringing down the economy, a group of scientists has released a study that shows a critical piece of the puzzle went missing, and that piece continues to go ignored, to everyone’s peril, including the banks.
Kepler finds first earth-size planets beyond our solar system
(PhysOrg.com) -- NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system. The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet's surface, but they are the smallest exoplanets ever confirmed around a star like our sun.
Universal transistor serves as a basis to perform any logic function
(PhysOrg.com) -- Most of today’s electronics devices contain two different types of field-effect transistors (FETs): n-type (which use electrons as the charge carrier) and p-type (which use holes). Generally, a transistor can only be one type or the other, but not both. Now in a new study, researchers have designed a transistor that can reconfigure itself as either n-type or p-type when programmed by an electric signal. A set of these “universal transistors” can, in principle, perform any Boolean logic operation, meaning circuits could perform the same number of logic functions with fewer transistors. This advantage could lead to more compact hardware and novel circuit designs.
Mystery of car battery's current solved
(PhysOrg.com) -- Chemists have solved the 150 year-old mystery of what gives the lead-acid battery, found under the bonnet of most cars, its unique ability to deliver a surge of current.
cb(3P): New particle at the Large Hadron Collider discovered by ATLAS experiment
(PhysOrg.com) -- Researchers from the University of Birmingham and Lancaster University, analysing data taken by the ATLAS experiment, have been at the centre of what is believed to be the first clear observation of a new particle at the Large Hadron Collider. The research is published today on the online repository arXiv.
Pions don't want to decay into faster-than-light neutrinos, study finds
When an international collaboration of physicists came up with a result that punched a hole in Einstein's theory of special relativity and couldn't find any mistakes in their work, they asked the world to take a second look at their experiment.
Study: Eating less keeps the brain young
Overeating may cause brain aging while eating less turns on a molecule that helps the brain stay young.
Let it snow! And five other super-fun Google tricks
Let it snow? Just in time for the holidays, Google has rolled out the latest in a string of neat tricks that you can play with the search engine.
A new kind of metal in the deep Earth
(PhysOrg.com) -- The crushing pressures and intense temperatures in Earth's deep interior squeeze atoms and electrons so closely together that they interact very differently. With depth materials change. New experiments and supercomputer computations discovered that iron oxide undergoes a new kind of transition under deep Earth conditions. Iron oxide, FeO, is a component of the second most abundant mineral at Earth's lower mantle, ferropericlase.
Neanderthal home made of mammoth bones discovered in Ukraine
(PhysOrg.com) -- Up till recently, most researchers studying Neanderthals had assumed they were simple wanderers, hiding out in caves when the weather got bad. Now however, the discovery of the underpinnings of a house built by a group of Neanderthals, some 44,000 years ago, turns that thinking on its head. Discovered by a team of French archeologists from the Muséum National d'Histories Naturelle, in an area that had been under study since 1984, the home, as it were, was apparently based on mammoth bones. The team’s findings are to be published in the science journal Quaternary International.
'Painless' plasma brush is becoming reality in dentistry, engineers say
University of Missouri engineers and their research collaborators at Nanova, Inc. are one step closer to a painless way to replace fillings. After favorable results in the lab, human clinical trials are underway on the "plasma brush."
Researchers develop paint-on solar cells (w/ video)
(PhysOrg.com) -- Imagine if the next coat of paint you put on the outside of your home generates electricity from light—electricity that can be used to power the appliances and equipment on the inside.
Secrets of the 'Levitating' Slinky: Viral web videos trigger physicists to explore a striking phenomenon
While holiday shoppers search frantically for the Moshi Monsters, LeapPad Explorers, or Lalaloopsy Silly Hair dolls atop their children's wish lists, many physicists remain engrossed in the properties of a simple 1940s-era toy -- the Slinky.
'Space ball' drops on Namibia
A large metallic ball fell out of the sky on a remote grassland in Namibia, prompting baffled authorities to contact NASA and the European space agency.
Scientists identify an innate function of vitamin E
It's rubbed on the skin to reduce signs of aging and consumed by athletes to improve endurance but scientists now have the first evidence of one of vitamin E's normal body functions.
Neuroscientists identify a master controller of memory
When you experience a new event, your brain encodes a memory of it by altering the connections between neurons. This requires turning on many genes in those neurons. Now, MIT neuroscientists have identified what may be a master gene that controls this complex process.
Special relativity from first principles
Einstein’s explanation of special relativity, delivered in his 1905 paper On the Electrodynamics of Moving Bodies focuses on demolishing the idea of ‘absolute rest’, exemplified by the theoretical luminiferous aether. He achieved this very successfully, but many hearing that argument today are left puzzled as to why everything seems to depend upon the speed of light in a vacuum.
IBM reveals five innovations that will change our lives in the next five years (Update)
Today IBM formally unveiled the sixth annual “IBM 5 in 5" (#ibm5in5) – a list of innovations that have the potential to change the way people work, live and interact during the next five years.
Underwater neutrino detector will be second-largest structure ever built
The hunt for elusive neutrinos will soon get its largest and most powerful tool yet: the enormous KM3NeT telescope, currently under development by a consortium of 40 institutions from ten European countries. Once completed KM3NeT will be the second-largest structure ever made by humans, after the Great Wall of China, and taller than the Burj Khalifa in Dubai… but submerged beneath 3,200 feet of ocean!
