Climate change reducing ocean's carbon dioxide uptake, new analysis shows

2011-07-11T20:47:00.000-07:00

ScienceDaily (2011-07-11) -- How deep is the ocean's capacity to buffer against climate change? As one of the planet's largest single carbon absorbers, the ocean takes up roughly one-third of all human carbon emissions, reducing atmospheric carbon dioxide and its associated global changes. But whether the ocean can continue mopping up human-produced carbon at the same rate is still up in the air. In a new analysis, researchers identify a likely source of many of those inconsistencies and provide some of the first observational evidence that climate change is negatively impacting the ocean carbon sink[.....]

Physicists discover new way to produce antimatter-containing atom

2011-07-11T20:45:00.000-07:00

ScienceDaily (2011-07-11) -- Physicists report that they have discovered a new way to create positronium, an exotic and short-lived atom that could help answer what happened to antimatter in the universe,why nature favored matter over antimatter at the universe's creation. The method works at almost any temperature -- including very low temperatures[....]

Physicists create supernova in a jar

2010-12-04T08:45:00.001-08:00

A team of physicists has mimicked a supernova -- an explosion of a star -- in miniature. In a certain type of supernova, the detonation starts with a flame ball buried deep inside a white dwarf. The flame ball is much lighter than its surroundings, so it rises rapidly making a plume topped with an accelerating smoke ring. In their experiment, the researchers created a smaller version of this process by triggering a special chemical reaction in a closed container that generates similar plumes and vortex rings.....

Dark matter could transfer energy in the Sun

2010-12-04T08:40:00.001-08:00

Researchers have studied the effects of the presence of dark matter in the Sun. According to their calculations, low mass dark matter particles could be transferring energy from the core to the external parts of the Sun, which would affect the quantity of neutrinos that reach Earth.[...]

Zapping Titan-like atmosphere with UV rays creates life precursors

2010-07-02T23:26:00.001-07:00

The first experimental evidence showing how atmospheric nitrogen can be incorporated into organic macromolecules is being reported by researchers. The finding indicates what organic molecules might be found on Titan, the moon of Saturn that scientists think is a model for the chemistry of pre-life Earth. Earth and Titan are the only known planetary-sized bodies that have thick, predominantly nitrogen atmospheres.[...]

Unpeeling atoms and molecules from the inside out

2010-07-02T23:18:00.000-07:00

The first published scientific results from the world's most powerful hard X-ray laser show its unique ability to control the behaviors of individual electrons within simple atoms and molecules by stripping them away, one by one -- in some cases creating hollow atoms.[...]

Astronomers have found an example of the rare type of supernova thought to produce Gamma Ray Bursts, but through radio, not gamma-ray, observations. The breakthrough, they say, will lead to discovering many more of these objects.

Toward safer plastics that lock in potentially harmful plasticizers

2010-02-06T03:40:00.000-08:00

Scientists have published the first report on a new way of preventing potentially harmful plasticizers -- the source of long-standing human health concerns -- from migrating from one of the most widely used groups of plastics.[....]

Computers that use light instead of electricity? First germanium laser created

2010-02-06T03:38:00.001-08:00

Researchers have demonstrated the first laser built from germanium that can emit wavelengths of light useful for optical communications. It's also the first germanium laser to operate at room temperature. Unlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips. So the result could prove an important step toward computers that move data -- and maybe even perform calculations -- using light instead of electricity.[....]

Where did today's spiral galaxies come from?

2010-02-06T03:35:00.000-08:00

Using data from the NASA/ESA Hubble Space Telescope, astronomers have created a demographic census of galaxy types and shapes from a time before the Earth and the sun existed, to the present day. The results show that more than half of the present-day spiral galaxies had peculiar shapes only six billion years ago, which, if confirmed, highlights the importance of collisions and mergers in the recent past of many galaxies. It also provides clues for the unique status of our own galaxy.[....]

Quantum mechanics at work in photosynthesis: Algae familiar with these processes for nearly two billion years

Potential evolutionary role for same-sex attraction

2010-02-05T06:20:00.000-08:00

Male homosexuality doesn't make complete sense from an evolutionary point of view. One possible explanation is what evolutionary psychologists call the "kin selection hypothesis." What that means is that homosexuality may convey an indirect benefit by enhancing the survival prospects of close relatives.

New visible light photocatalyst kills bacteria, even after light turned off

2010-02-01T04:17:00.001-08:00

In the battle against bacteria, researchers have developed a powerful new weapon -- an enhanced photocatalytic disinfection process that uses visible light to destroy harmful bacteria and viruses, even in the dark.[...]

Watching crystals grow provides clues to making smoother, defect-free thin films

2010-02-01T04:15:00.000-08:00

To make thin films for semiconductors in electronic devices, layers of atoms must be grown in neat, crystalline sheets. But while some materials grow smooth crystals, others tend to develop bumps and defects -- a serious problem for thin-film manufacturing. Physicists shed new light on how atoms arrange themselves into thin films.[...]

Key Milestone Reached on Road to Graphene-Based Electronic Devices

2010-02-01T04:13:00.001-08:00

Researchers have produced 100mm diameter graphene wafers, a key milestone in the development of graphene for next generation high frequency electronic devices. Graphene is a 2-dimensional layer of tightly bound carbon atoms arranged in hexagonal arrays. Sheets of graphene are the building blocks of graphite. Due to its phenomenal electronic properties, graphene has been considered as a leading material for next generation electronic devices in the multibillion dollar semiconductor industry.[...]

Atoms and Molecules: Using magnetic toys as inspiration, researchers tease out structures of self-assembled clusters

2010-02-01T04:11:00.001-08:00

Scientists have discovered new clues to how and why groups of atoms and molecules may favor less symmetrical and more complex, flexible geometric patterns. The answer relates to a familiar concept in physics -- entropy. The researchers literally first caught sight of the link by using magnetic "stick and ball" construction toys.[...]

Experiments meet requirements for fusion ignition; new physics effect achieves symmetrical target compression

2010-01-31T06:03:00.000-08:00

The first experiments at Lawrence Livermore National Laboratory's National Ignition Facility (NIF) have demonstrated a unique physics effect that bodes well for NIF's success in generating a self-sustaining nuclear fusion reaction. In inertial confinement fusion experiments on NIF, the energy of 192 powerful laser beams is fired into a pencil-eraser-sized cylinder called a hohlraum, which contains a tiny spherical target filled with deuterium and tritium, two isotopes of hydrogen. Rocket-like compression of the fuel capsule forces the hydrogen nuclei to combine, or fuse, releasing many times more energy than the laser energy that was required to spark the reaction.[...]

Jupiter's Moons: Explanation for the Differences Between Ganymede and Callisto

2010-01-31T05:58:00.000-08:00

Differences in the number and speed of cometary impacts onto Jupiter's large moons Ganymede and Callisto some 3.8 billion years ago can explain their vastly different surfaces and interior states, according to new research.[...]

Scent of a woman: Men's testosterone responses to olfactory ovulation cues

2010-01-19T02:48:00.000-08:00

Women around the world spend billions of dollars each year on exotic smelling perfumes and lotions in the hopes of attracting a mate. However, going "au natural" may be the best way to capture a potential mate's attention: Men who smelled shirts of ovulating women subsequently had higher levels of testosterone than men who smelled shirts worn by non-ovulating women, suggesting that testosterone levels may be responsive to smells indicating when a woman is fertile.[...]
