True muonium, a long-theorized but never-seen atom-like configuration of a muon and its anti-particle, might be observed in future experiments thanks to recent theoretical work by researchers. True muonium was first theorized more than 50 years ago, but until now no one had uncovered an unambiguous method by which it could be created and observed.
Researchers from the University of California at Berkeley have developed a new carbon nanotube-based technique that could potentially store data that lasts more than a billion years.
In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists have created a simple slab of metal that lifts liquid using the same principle -- but at much greater speed.
Olive waste obtained during the oil extraction process may be used to eliminate heavy metals from sewage or waste waters of productive activities. The olive industry produces great amounts of such sub-products in and their cost is very low or nothing.
Physicists have demonstrated entanglement -- a phenomenon peculiar to the atomic-scale quantum world -- in a mechanical system similar to those in the macroscopic everyday world. The work extends the boundaries of the arena where quantum behavior can be observed and shows how laboratory technology might be scaled up to build a functional quantum computer.

As a fast and efficient means of transport, jellyfish-like organisms could play a major role in the marine carbon cycle. Marine biologists report that dead bodies of the marine organism Pyrosoma atlanticum may be transporting much more carbon to the seafloor than phytoplankton or other jellyfish-like creatures.
Researchers at the University of Pennsylvania have immunized monkeys against the simian immunodeficiency virus, the animal model that is closest to HIV. They did so by shuttling a gene into the monkeys' muscles, making the muscle cells produce antibody-like molecules that work against SIV.
Periodical cicadas, insects best known for their 17-year long life cycle, are emerging four years early in several Atlantic states. The emergence was first noticed in Greensboro, NC, early in May and has since been reported in Maryland.

Scientists have developed an efficient method to detect entanglement shared among multiple parts of an optical system. They show how entanglement, in the form of beams of light simultaneously propagating along four distinct paths, can be detected with a small number of measurements. Entanglement is an essential resource in quantum information science, which is the study of advanced computation and communication based on the laws of quantum mechanics.

Astronomers suspect that hundreds of medium-sized black holes are roaming loose in the Milky Way. These rogues, according to a new study, are the orphaned central black holes of the many smaller galaxies that the Milky Way has swallowed over its billions of years of existence.
Ten years ago, Stanford University School of Medicine scientist Emmanuel Mignot, M.D., Ph.D., and his colleagues made headlines when they identified the culprit behind the sleep disorder narcolepsy. Now Mignot and his collaborators have shown for the first time that a specific immune cell is involved in the disorder -- confirming experts' long-held suspicion that narcolepsy is an autoimmune disease.
Biologists have discovered that zebra finches raised in isolation will, over several generations, produce a song similar to that sung by the species in the wild. The experiment provides new insights into how genetic background, learning abilities and environmental variation might influence how birds evolve "song culture" -- and provides some pointers to how human languages may evolve.

A reservoir of briny liquid buried deep beneath an Antarctic glacier supports hardy microbes that have lived in isolation for millions of years, researchers report in the journal Science. Chemical analysis of effluent from the inaccessible subglacial pool suggests that its inhabitants have eked out a living by breathing iron leached from bedrock with the help of a sulfur catalyst.

Scientists from the UK and Germany are proposing a third kind of quantum tunneling. They propose that a quantum particle is capable of changing into a pair of "virtual particles" capable of passing through a potential barrier before changing back. The supposition also provides some interesting methods of possibly testing string theory.
Plants absorbed carbon dioxide more efficiently under the polluted skies of recent decades than they would have done in a cleaner atmosphere, according to new findings.

A US citizen who tried to board a domestic airplane while carrying $4700 in cash was detained by the TSA and subjected to abusive language and threats when he said that he would only answer the TSA's inquiries, such as, "Where do you work?" and,"Why are you carrying cash?" if he was required to by law.
New York City's Metropolitan Transit Authority is planning to roll out a new blog next month focusing on hipster central, the L line, which serves Williamsburg and Bushwick and is one of the fastest growing riderships in the system.
Matt Stone and Trey Parker, the creators of South Park, were given a very special gift by US marines: a signed photo of Saddam Hussein. During his captivity, the marines forced Saddam to repeatedly watch the movie South Park: Bigger, Longer And Uncut, which shows him as the boyfriend of Satan. Stone said, "We're very proud of our signed Saddam picture and what it means. It's one of our biggest highlights."

Australian scientists have made a discovery that may one day remove the need for a lifetime of toxic immunosuppressive drugs after organ transplantation.
A bad connection in the brains of schizophrenic patients seems to leave them unaffected by a common optical illusion that turns the concave backside of a mask into a convex face. The difference may be a disconnect in the schizophrenic brain between what it actually sees and what it expects to see based on past experience.
In a finding that may help speed the production of ultra-clean fuel cell vehicles powered by hydrogen, scientists in Michigan are reporting development of a sponge-like nanomaterial with a record-high surface area for holding gases. Just 1/30th of an ounce of the material has the approximate surface area of a football field.
Researchers have developed an entirely new method for starting chemical reactions. For the first time, they used mechanical forces to control catalytic activity -- one of the most fundamental concepts in chemistry. This allowed them to initiate chemical reactions with mechanical force. This discovery paves the way to developing materials capable of repairing themselves under the influence of mechanical tension.
Discovery of an efficient artificial catalyst for the sunlight-driven splitting of water into oxygen and hydrogen is a major goal of renewable clean energy research. Scientists have devised a unique new mechanism for the formation of hydrogen and oxygen from water, without the need for sacrificial chemical agents, through individual steps, using light.
Sunspot activity is on track to beat last year's near historical low. 2008 saw no sunspot activity on 266 out of 366, or 73 percent, of its days. To find a year with less sunspot activity, you'd have to go back to 1913, which had 311 spotless days. But sunspot counts for 2009 have dropped even lower. As of March 31st, there were no sunspots on 78 of the year's 90 days, or 87 percent.
Though greenhouse gases are invariably at the center of discussions about global climate change, new NASA research suggests that much of the atmospheric warming observed in the Arctic since 1976 may be due to changes in tiny airborne particles called aerosols.
