Antimatter atoms have been trapped for the first time, scientists say. Researchers at Cern, home of the Large Hadron Collider, have held 38 antihydrogen atoms in place, each for a fraction of a second. Antihydrogen has been produced before but it was instantly destroyed when it encountered normal matter. The team, reporting in Nature, says the ability to study such antimatter atoms will allow previously impossible tests of fundamental tenets of physics. The current "standard model" of physics holds that each particle - protons, electrons, neutrons and a zoo of more exotic particles - has its mirror image antiparticle. The...

After 16 years and $1.5 billion of other people’s money, it is almost showtime for NASA and Sam Ting. Sitting and being fussed over by technicians in a clean room at the Kennedy Space Center in preparation for a February launching — and looking for all the world like a giant corrugated rain barrel — is an eight-ton assemblage of magnets, wires, iron, aluminum, silicon and electronics that is one of the most ambitious and complicated experiments ever to set out for space. The experiment, if it succeeds, could help NASA take a giant step toward answering the question of...

Allan R. Sandage, who spent his life measuring the universe, becoming the most influential astronomer of his generation, died Saturday at his home in San Gabriel, Calif. He was 84. The cause was pancreatic cancer, according to an announcement by the Carnegie Observatories, where he had spent his whole professional career. Over more than six decades, Dr. Sandage was like one of those giant galaxies that sit at the center of a cluster of galaxies, dominating cosmic weather. He wrote more than 500 papers, ranging across the cosmos, covering the evolution and behavior of stars, the birth of the Milky...

A gamma-ray burst is an immensely powerful blast of high-energy light thought to be generated by a collapsing star in a distant galaxy, but what this collapse leaves behind has been a matter of debate. A new analysis of four extremely bright bursts observed by NASA's Fermi satellite suggests that the remnant from a long-duration gamma-ray burst is most likely a black hole - not a rapidly spinning, highly magnetised neutron star, or magnetar since such a burst emits more energy than is theoretically possible from a magnetar. 'Some of the events we have been finding seem to be pushing...

From the idea that our universe is one among many, to the revelation that mathematician Pythagoras didn't actually invent the Pythagorean theorem, here are eight shocking things we learned from reading physicist Stephen Hawking's new book, "The Grand Design," written with fellow physicist Leonard Mlodinow of Caltech. This book, covering major questions about the nature and origin of the universe, was released Sept. 7 by its publisher, Bantam. 1. The past is possibility According to Hawking and Mlodinow, one consequence of the theory of quantum mechanics is that events in the past that were not directly observed did not happen...

Chinese Lab Creates Artificial Black Hole October 14th, 2009, 12:48 GMT| By Tudor Vieru Far from being the only ones attempting to create an artificial black hole, Chinese researchers recently announced that they were able to produce the first artificial black hole for microwaves. If light in this energy spectrum enters the construct, it can no longer leave it, the team reports. Its accomplishment was made possible through the use of metamaterials, the same components that form the basis for invisibility cloaks and other optoelectronic devices, Technology Review reports. In charge of the Chinese team were scientists Qiang Cheng and...

The two vast structures, stretching to the north and to the south of the centre of the Milky Way, are so big that a beam of light, travelling at 186,282 miles per second, would take 50,000 years to get from the edge of one to the edge of the other. The previously unseen bubbles were discovered by astronomer Doug Finkbeiner, of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, using NASA's Fermi Gamma-Ray Telescope. He admitted yesterday: "We don't fully understand their nature or origin." They span more than half the visible sky, from the constellation of Virgo to the...

WASHINGTON (AFP) – Two huge, unexplained gamma ray emitting bubbles have been discovered at the center of the Milky Way galaxy, US astronomers said Tuesday. Masked by a fog of gamma rays that appears throughout the sky, the bubbles form a feature spanning 50,000 light-years and could be the remnant of a supersized black hole eruption or the outflows from a burst of star formation, the astronomers said. The structure spans more than half of the visible sky, from the constellation Virgo to the constellation Grus, and it may be millions of years old, the astronomers said in a paper...

Is Precognition Real? Cornell University Lab Releases Powerful New Evidence that the Human Mind can Perceive the Future Written By: Ben Goertzel Date Published: November 4, 2010 According to today’s conventional scientific wisdom, time flows strictly forward — from the past to the future through the present. We can remember the past, and we can predict the future based on the past (albeit imperfectly) — but we can’t perceive the future. But if the recent data from the lab of Prof. Daryl Bem at Cornell University is correct, conventional scientific wisdom may need some corrections on this particular point. In...

GENEVA – Scientists at the world's largest atom smasher said Monday they have succeeded in recreating conditions shortly after the Big Bang by switching the particles they use for collisions from protons to much heavier lead ions. The Large Hadron Collider recorded its first lead ion collisions on Sunday and has since stabilized the twin beams sufficiently to start running physics experiments, said a spokeswoman for the European Organization for Nuclear Research, or CERN. The collisions produce an effect that is as close as researchers have ever come to observing the state of matter moments after the formation of the...

A new supernova? Darn right. Lighting up Leo? Well… not without some serious visual aid, but the fact that someone out there is watching and has invited us along for the ride is mighty important. And just who might that someone be? None other than Tim Puckett. Less than 24 hours ago, the American Association of Variable Star Observer’s Report #222 stated: “Bright Supernova in UGC 5189A: SN 2010jl November 5, 2010 We have been informed by Tim Puckett and by the Central Bureau for Astronomical Telegrams (CBET 2532, Daniel W. E. Green, Ed.) of the discovery of a bright...

During the hunt for the predicted ripples in space-time — known as gravitational waves — physicists stumbled across a rather puzzling phenomenon. Last year, I reported about the findings of scientists using the GEO600 experiment in Germany. Although the hi-tech piece of kit hadn’t turned up evidence for the gravitational waves it was seeking, it did turn up a lot of noise. snip As it turns out, Hogan thinks that noise at these scales are caused by a holographic projection from the horizon of our universe.

Today physicists announced that they may have found the key to explaining dark matter in the universe. It all has to do with the potential discovery of a "sterile neutrino." According to a release about the new study: Neutrinos are neutral elementary particles born in the radioactive decay of other particles. The known "flavors" of neutrinos are the neutral counterparts of electrons and their heavier cousins, muons and taus. Regardless of a neutrino's original flavor, the particles constantly flip from one type to another in a phenomenon called "neutrino flavor oscillation." An electron neutrino might become a muon neutrino, and...

Our universe has existed for nearly 14 billion years, and as far as most people are concerned, the universe should continue to exist for billions of years more. But according to a new paper, there's one theory for the origins of the universe that predicts time itself will end in just five billion years—coincidentally, right around the time our sun is slated to die.The prediction comes from the theory of eternal inflation, which says our universe is part of the multiverse. This vast structure is made up of an infinite number of universes, each of which can spawn an infinite...

CORVALLIS, Ore. – Researchers at Oregon State University have solved a quest in fundamental material science that has eluded scientists since the 1960s, and could form the basis of a new approach to electronics. The discovery, just reported online in the professional journal Advanced Materials, outlines the creation for the first time of a high-performance "metal-insulator-metal" diode. "Researchers have been trying to do this for decades, until now without success," said Douglas Keszler, a distinguished professor of chemistry at OSU and one of the nation's leading material science researchers. "Diodes made previously with other approaches always had poor yield and...

Pairs of photons linked by the weird quantum effect of entanglement can pass through sheets of metal without the entanglement being destroyed. The finding means the quantum linking of particles is far more robust than scientists thought and could help them develop new ways of making quantum computers. Scientists think quantum computers could be hugely powerful because of their ability to perform many calculations at once, instead of doing one after another like regular computers. When photons are entangled, the physical properties of one are intimately linked to the other. Measuring the properties of one will instantly tell you the...

Benoit B. Mandelbrot, a maverick mathematician who developed an innovative theory of roughness and applied it to physics, biology, finance and many other fields, died on Thursday in Cambridge, Mass. He was 85. His death, at a hospice, was caused by pancreatic cancer, his wife, Aliette, said. He had lived in Cambridge. Dr. Mandelbrot coined the term “fractal” to refer to a new class of mathematical shapes whose uneven contours could mimic the irregularities found in nature. “Applied mathematics had been concentrating for a century on phenomena which were smooth, but many things were not like that: the more you...

How fast should a wet dog rotate its body to dry its fur? It's a question that many dog owners will have spent sleepless nights pondering. How rapidly should a wet dog oscillate its body to dry its fur? Today we have an answer thanks to the pioneering work of Andrew Dickerson at the Georgia Institute of Technology in Atlanta and a few buddies. But more than that, their work generates an interesting new conundrum about the nature of shaken fur dynamics. Dickerson and co filmed a number of dogs shaking their fur and used the images to measure the...

Homing in on an object found during the Hubble Space Telescope's long, deep stare into the distant past, astronomers have fished out a galaxy whose light has traveled more than 13 billion light-years to get here, making it the oldest astronomical object found so far. The universe's most senior citizen is called UDFy-38135539, but scientists suspect its title as record-holder -- previously held by a gamma-ray burst -- will not last.
