The leading edge of the first of two major coronal mass ejections will reach Earth at about 1:25 AM EST on the morning of March 8 (plus or minus 7 hours). Such a CME could result in a severe geomagnetic storm, causing aurora at low latitudes, with possible disruption to high frequency radio communication, global positioning systems (GPS), and power grids.
The Daya Bay Reactor Neutrino Experiment, a multinational collaboration operating in the south of China, today reported the first results of its search for the last, most elusive piece of a long-standing puzzle: how is it that neutrinos can appear to vanish as they travel? The surprising answer opens a gateway to a new understanding of fundamental physics and may eventually solve the riddle of why there is far more ordinary matter than antimatter in the universe today.
(PhysOrg.com) -- IBM scientists today will report on a prototype optical chipset, dubbed “Holey Optochip”, that is the first parallel optical transceiver to transfer one trillion bits – one terabit – of information per second, the equivalent of downloading 500 high definition movies. The report will be presented at the Optical Fiber Communication Conference taking place in Los Angeles.
The ALPHA collaboration at CERN in Geneva has scored another coup on the antimatter front by performing the first-ever spectroscopic measurements of the internal state of the antihydrogen atom. Their results are reported in a forthcoming issue of Nature and are now online.
The latest measurement of the mass of the W boson from the Tevatron experiments. The new combined result is twice as precise as the previous world average, and places limits on the mass of the Higgs consistent with the limits from direct searches at the LHC and Tevatron.
Scientists suggest that renewable energy is a viable option for electrical power in developing and emerging nations. Researchers point out that in most of these nations, the demand for energy far exceeds the generating capacity.
We know since the dawn of modern physics that although events in our everyday life can be described by classical physics, the interaction of light and matter is down deep governed by the laws of quantum mechanics. Despite this century-old wisdom, accessing truly quantum mechanical situations remains nontrivial, fascinating and noteworthy even in the laboratory. Recently, interest in this area has been boosted beyond academic curiosity because of the potential for more efficient and novel forms of information processing.
Scientists have created a new way to overcome many of the issues associated with bringing high-speed digital communications across challenging terrain and into remote areas, commonly referred to as the "last mile" problem. The researchers developed a record-speed wireless data bridge that transmits digital information much faster than today
New laser light source has a global market in consumer electronics. Mobile phones currently on the market are capable of showing high quality images and video, but the phones
People with higher trust in their feelings were more likely to correctly predict a variety of future events. The researchers call this phenomenon the emotional oracle effect.
Researchers have discovered the means by which a polymer known as PVDF enables capacitors to store and release large amounts of energy quickly. Their findings could lead to much more powerful and efficient electric cars.
Los Alamos National Laboratory scientists and an international research team have announced discovery of molecular oxygen ions (O2+) in the upper-most atmosphere of Dione, one of the 62 known moons orbiting the ringed planet. The research appeared recently in Geophysical Research Letters and was made possible via instruments aboard NASA's Cassini spacecraft, which was launched in 1997.
Many of the communication tools of today rely on the function of light or, more specifically, on applying information to a light wave. Up until now, studies on electronic and optical devices with materials that are the foundations of modern electronics -- such as radio, TV, and computers -- have generally relied on nonlinear optical effects, producing devices whose bandwidth has been limited to the gigahertz (GHz) frequency region. (Hertz stands for cycles per second of a periodic phenomenon, in this case 1billion cycles).
In the grand scheme of the solar system, Venus and Earth are almost the same distance from the sun. Yet the planets differ dramatically: Venus is some 100 times hotter than Earth and its days more than 200 times longer. The atmosphere on Venus is so thick that the longest any spacecraft has survived on its surface before being crushed is a little over two hours. There's another difference, too. Earth has a magnetic field and Venus does not -- a crucial distinction when assessing the effects of the sun on each planet.
