New pint sized particle accelerator leads the way to clean nuclear energy
(PhysOrg.com) -- Researchers at Daresbury science park in Britain have offered a glimpse into what might be the future of nuclear energy production by showcasing a scaled down particle accelerator; one, that when combined with others just like it, could produce nuclear energy based on thorium, rather than uranium. Dubbed the Electron Machine with Many Applications (EMMA), the accelerator, a much smaller version of the kind used in physics research, such as the Large Hadron Collider, could be used to provide an accelerated beam necessary for the type of nuclear reaction used in a theoretical thorium plant.
Biologists discover how yeast cells reverse aging
Human cells have a finite lifespan: They can only divide a certain number of times before they die. However, that lifespan is reset when reproductive cells are formed, which is why the children of a 20-year-old man have the same life expectancy as those of an 80-year-old man.
Nanotechnology pushes battery life to eternity
(PhysOrg.com) -- A simple tap from your finger may be enough to charge your portable device thanks to a discovery made at RMIT University and Australian National University.
Austrian company debuts revolutionary wingless aircraft
(PhysOrg.com) -- A firm from Austria, Austrian Innovative Aeronautical Technology (IAT21) has unveiled a new type of aircraft that flies without wings or rotors, at the Paris Air Show. Though not actually flown at the show, spokesmen for the new aircraft, named D-Dalus (no doubt after the tragic Greek figure Daedalus, who lost his son Icarus when his wings melted as he flew too close to the sun) claim the aircraft is capable of both hovering and flying forward as fast as a jet, all with very little noise.
Lab-grown meat would 'cut emissions and save energy'
(PhysOrg.com) -- Meat grown using tissue engineering techniques, so-called ‘cultured meat’, would generate up to 96% lower greenhouse gas emissions than conventionally produced meat, according to a new study.
Study finds single photons cannot exceed the speed of light
(PhysOrg.com) -- The rule that nothing can travel faster than the speed of light, c, is one of the most fundamental laws of nature. But since this speed limit has only been experimentally demonstrated for information carried by large groups of photons, physicists have recently speculated as to whether single photons and the information carried by them may be able to exceed the speed of light. In a new study, physicists have performed the difficult task of producing single photons with controllable waveforms, and have shown that single photons also obey the speed limit c.
'Super sand' for better purification of drinking water (Update)
(PhysOrg.com) -- Scientists have developed a way to transform ordinary sand -- a mainstay filter material used to purify drinking water throughout the world -- into a "super sand" with five times the filtering capacity of regular sand. The new material could be a low-cost boon for developing countries, where more than a billion people lack clean drinking water, according to the report in the ACS journal Applied Materials & Interfaces.
Scientists find simple way to produce graphene
(PhysOrg.com) -- Scientists at Northern Illinois University say they have discovered a simple method for producing high yields of graphene, a highly touted carbon nanostructure that some believe could replace silicon as the technological fabric of the future.
Strongest evidence yet indicates Enceladus hiding saltwater ocean
(PhysOrg.com) -- Samples of icy spray shooting from Saturn's moon Enceladus collected during Cassini spacecraft flybys show the strongest evidence yet for the existence of a large-scale, subterranean saltwater ocean, says a new international study led by the University of Heidelberg and involving the University of Colorado Boulder.
Quantum leaper
(PhysOrg.com) -- Acclaimed for a breakthrough algorithm, physicist Steven White is now first to model a new state of matter.
Baby star blasts jets of water into space
Astronomers have found a nascent star 750 light years from earth that shoots colossal jets of water -- a cosmic fire hose -- out its poles in bullet-like pulses.
Another asteroid to give Earth a close shave June 27, 2011
(PhysOrg.com) -- A newly discovered house-sized asteroid will miss the Earth by less than 17,700 km (11,000 miles) on Monday June 27, 2011. That’s about 23 times closer than the Moon. The size and location of the asteroid, named 2011 MD, should allow observers in certain locations to take a look at the space rock, even with small telescopes. It’s closest approach will be at 13:26 UTC on June 27.
When matter melts: Physicists map phase changes in quark-gluon plasma
In its infancy, when the universe was a few millionths of a second old, the elemental constituents of matter moved freely in a hot, dense soup of quarks and gluons. As the universe expanded, this quark–gluon plasma quickly cooled, and protons and neutrons and other forms of normal matter "froze out": the quarks became bound together by the exchange of gluons, the carriers of the color force.
Genius of Einstein, Fourier key to new humanlike computer vision
(PhysOrg.com) -- Two new techniques for computer-vision technology mimic how humans perceive three-dimensional shapes by instantly recognizing objects no matter how they are twisted or bent, an advance that could help machines see more like people.
Oceans in distress foreshadow mass extinction
Pollution and global warming are pushing the world's oceans to the brink of a mass extinction of marine life unseen for tens of millions of years, a consortium of scientists warned Monday.
Start up creates a 'no-focus' point and shoot camera
(PhysOrg.com) -- If you have ever used a "Point and Shoot" style of camera in the last few years then you know that that term is a misnomer because unless you are using a disposable camera you are going to be waiting for that camera to auto-focus and that focus can take up to 45 seconds to find its focus and allow you to take a picture. It is annoying to say the least if the action that you wanted a picture of can't be stopped like a posed photo. Since that focus can mean that you may miss a winning goal or a really cute moment it can be more than just annoying.
Body temperatures of dinosaurs measured for the first time
(PhysOrg.com) -- Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold or warm blooded. When dinosaurs were first discovered in the mid-19th century, paleontologists thought they were plodding beasts that had to rely on their environments to keep warm, like modern-day reptiles. But research during the last few decades suggests that they were faster creatures, nimble like the velociraptors or T. rex depicted in the movie Jurassic Park, requiring warmer, regulated body temperatures like in mammals.
Human infants capable of advanced reasoning
(Medical Xpress) -- Recent research reported in PhysOrg showed that babies seem to be able to distinguish right from wrong even at the age of six months, and consistently choose helpful characters over unhelpful ones. Now new research suggests very young children are also able to use advanced reasoning to solve problems.
Astronomers find evidence for a strange new planetary system
(PhysOrg.com) -- A team of astronomers, including Dr Gavin Ramsay of the Armagh Observatory, has found evidence that suggests the existence of an extraordinary planetary system. Two giant planets appear to be revolving at some distance around a compact, interacting stellar binary known as UZ For, which comprises two small stars orbiting very closely one about the other.
New study finds HIV Achilles Heel
(Medical Xpress) -- A new study published in the Proceedings of the National Academy of Sciences shows how scientists have used a mathematical tool to possibly identify an Achilles heel in HIV which may lead to new vaccines and treatments.
