Physicists have examined how Bose-Einstein condensates (BEC) might be used to provide communication among the nodes of a distributed quantum computer. The researchers determined the amount of time needed for quantum information to propagate across their BEC.
The irony of getting away to a remote place is you usually have to fight traffic to get there. After hours of dodging dangerous drivers, you finally arrive at that quiet mountain retreat, stare at the gentle waters of a pristine lake, and congratulate your tired self on having "turned off your brain."
University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3-D as they fell – and they don’t look much like those perfect-but-rare snowflakes often seen in photos.

NASA's Hubble Space Telescope has broken the record in the quest to find the farthest supernova of the type used to measure cosmic distances. The supernova exploded more than 10 billion years ago (redshift 1.914). At that time, the universe was in its early formative years where stars were being born at a rapid rate.
If the sheet of ice covering Greenland were to melt in its entirety tomorrow, global sea levels would rise by 24 feet. Three million cubic kilometers of ice won’t wash into the ocean overnight, but researchers have been tracking increasing melt rates since at least 1979. Last summer, however, the melt was so large that similar events show up in ice core records only once every 150 years or so over the last four millennia.
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. Many navigators used this object to make their way across the oceans. A new composite image from three NASA telescopes -- Chandra, Hubble, and Spitzer -- shows this galaxy like Ferdinand Magellan, who lends his name to the SMC, could never have imagined.
As the shapes of galaxies go, the spiral disk — with its characteristic pinwheel profile — is by far the most pedestrian.
The largest harmful algae bloom in Lake Erie's recorded history was likely caused by the confluence of changing farming practices and weather conditions that are expected to become more common in the future due to climate change.
Surface appearances can be so misleading: In most forests, the amount of carbon held in soils is substantially greater than the amount contained in the trees themselves.
Dark and sleek, it hides beneath the water waiting for prey. A Texas Tech University researcher says the target will never know what hit them because they probably can’t smell the voracious pirate perch.
A new study led by WCS-India scientist Vidya Athreaya finds that certain landscapes of western India completely devoid of wilderness and with high human populations are crawling with a different kind of backyard wildlife: leopards.
Virginia Tech College of Engineering researchers have unveiled Cyro, a life-like, autonomous robotic jellyfish the size and weight of a grown man, 5 foot 7 inches in length and weighing 170 pounds.
Geneva, 25 March 2013. In today's Physical Review Letters, the Antihydrogen TRAP (ATRAP1) experiment at CERN2's Antiproton Decelerator (AD) reports a new measurement of the antiprotonmagnetic moment made with an unprecedented uncertainty of 4.4 parts per million (ppm). This result is 680 times more precise than previous measurements. The unusual increase in precision is due to the experiment’s ability to trap individual protons and antiprotons, and to using a huge magnetic gradient to gain sensitivity to the tiny magnetic moment. ATRAP’s new result is partly an attempt to understand the matter-antimatter imbalance of the universe, one of the great mysteries of modern physics.
Stars ten times as massive as the Sun, or more, should not exist: as they grow, they tend to push away the gas they feed on, starving their own growth. Scientists have been struggling to figure out how some stars overcome this hurdle. Now, a group of researchers led by two astronomers at the University of Toronto suggests that baby stars may grow to great mass if they happen to be born within a corral of older stars.
In the latest achievement in efforts to see what may lie underneath the surface of great works of art, scientists today described the first use of an imaging technology like that used in airport whole-body security scanners to detect the face of an ancient Roman man hidden below the surface of a wall painting in the Louvre Museum in Paris.
Analyses of clam shells used in ancient funeral ceremonies offer additional evidence as to how climate change may have contributed to the gradual collapse of an early South-American civilization, according to research publishing earlier this month.

People think of wind as an energy source with few limits, offering an unending power source with distinct capacity advantages over sources that deplete, such as fossil fuel. Yet, new research in mesoscale atmospheric modeling by UNC Charlotte's Amanda S. Adams and Harvard University's David W. Keith, published Monday in the journal Environmental Research Letters, suggests that the power capacity of large-scale wind farms may have been significantly overestimated.
Ancient rises in sea levels and global warming are partially attributable to cyclical activity below the earth’s surface, researchers from New York University and Ottawa’s Carleton University have concluded in an analysis of geological studies.

When Gulf of Mexico algae don’t get enough nutrients, they focus their remaining energy on becoming more and more poisonous to ensure their survival, according to a new study.
Fungi, with the exception of shitake and certain other mushrooms, tend to be something we associate with moldy bread or dank-smelling mildew. But they really deserve more respect, say Union College researchers, Steve Horton and Ron Bucinell. Fungi have fantastic capabilities and can be grown, under certain circumstances, in almost any shape and be totally biodegradable. And, if this weren’t enough, they might have the potential to replace plastics one day. The secret is in the mycelia.
Cryptic comments seem to have an ambiguous, obscure or hidden meaning. In biology, cryptic species are outwardly indistinguishable groups whose differences are hidden inside their genes.
Columbia Engineering’s new “plug-and-play” method to assemble complex cell microenvironments is a scalable, highly precise way to fabricate tissues with any spatial organization or interest—like those found in the heart or skeleton or vasculature. The PNAS study reveals new ways to better mimic the enormous complexity of tissue development, regeneration, and disease.
