UC San Diego Physicists Reveal Secrets of Newest Form of Carbon
Using one of the world's most powerful sources of man-made radiation, physicists from UC San Diego, Columbia University and Lawrence Berkeley National Laboratory have uncovered new secrets about the properties of graphene-a form of pure carbon that may one day replace the silicon in computers,... view more (2008-06-11)

NASA's Swift satellite images a galaxy ablaze with starbirth
Combining 39 individual frames taken over 11 hours of exposure time, NASA astronomers have created this ultraviolet mosaic of the nearby "Triangulum Galaxy."   view more (2008-02-26)

Ultrafast lasers take 'snapshots' as atoms collide
Using laser pulses that last just 70 femtoseconds (quadrillionths of a second), physicists have observed in greater detail than ever before what happens when atoms collide.   view more (2005-10-21)

Structural basis for photoswitching in fluorescent proteins brought into focus
University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours.   view more (2007-04-11)

Separate signals through optical fibres for ultrafast home network
Dutch-sponsored researcher Christos Tsekrekos has investigated how a small network for at home or in a company can function optimally. His research analyses the MGDM technique (Mode Group Diversity Multiplexing) of the Eindhoven University of Technology.   view more (2008-01-25)

Team revamps energy system for fuel-efficiency
MIT researchers are trying to unleash the promise of an old idea by converting light into electricity more efficiently than ever before.   view more (2006-05-23)

Multiple genes permit closely related fish species to mix and match their color vision
Vision, like other biological attributes, is shaped by evolution through environmental pressures and demands, and even closely-related species that are in other ways very similar might respond to their particular environments by interpreting the visual world slightly differently, using... view more (2005-10-11)

Northern lights glimmer with unexpected trait
An international team of scientists has detected that some of the glow of Earth's aurora is polarized, an unexpected state for such emissions.   view more (2008-04-28)

Laser trapping of erbium may lead to novel devices
Physicists at the National Institute of Standards and Technology (NIST) have used lasers to cool and trap erbium atoms, a "rare earth" heavy metal with unusual optical, electronic and magnetic properties.   view more (2006-05-01)

High efficiency flat light source invented
Scientists studying organic light-emitting devices (OLEDs) have made a critical leap from single-color displays to a highly efficient and long-lived natural light source.   view more (2006-04-13)

Fast quantum computer building block created
The fastest quantum computer bit that exploits the main advantage of the qubit over the conventional bit has been demonstrated by researchers at University of Michigan, U.S. Naval Research Laboratory and the University of California at San Diego.   view more (2008-08-21)

Flies in a spider's web: Galaxy caught in the making
In nature spiders earn our respect by constructing fascinating, well-organised webs in all shapes and sizes. But the beauty masks a cruel, fatal trap. Analogously, the NASA/ESA Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth (at a redshift of 2.2) that is... view more (2006-10-12)

A sub-femtosecond stop watch for 'photon finish' races
Using a system that can compare the travel times of two photons with sub-femtosecond precision, scientists at the Joint Quantum Institute (a partnership of the National Institute of Standards and Technology (NIST) and the University of Maryland) and Georgetown University have found a remarkably... view more (2008-03-14)

Theory of oscillations may explain biological mysteries
New mathematical studies of the interactions between oscillating biological populations may shed light on some of the toughest questions in ecology, including the number and types of species in an ecosystem, according to an article in the December 2006 issue of BioScience.   view more (2006-12-04)

Astronomers find grains of sand around distant stars
In a find that sheds light on how Earth-like planets may form, astronomers this week reported finding the first evidence of small, sandy particles orbiting a newborn solar system at about the same distance as the Earth orbits the sun. The report will be published online this week by the journal... view more (2008-03-13)

Nanotube flickering reveals single-molecule rendezvous
In the quantum world, photons and electrons dance, bump and carry out transactions that govern everything we see in the world around us.   view more (2007-06-08)

Using light under your skin
You have a tiny wound on your hand that doesn't heal, a bad burn on your chest - or an injured retina. Your doctor cannot tell how serious the injuries are below the surface. He needs tissue samples. That means using a scalpel, which again equals pain, perhaps even a risk. Soon there may be hope... view more (2005-04-21)

Food could be made safer by surface decontamination with steam
Trials have been carried out using steam below, at, or above atmospheric pressure. As the pressure of the steam is increased, higher decontamination temperatures can be achieved. Comparative studies are also assessing the use of treatments with hot air, water immersion, infrared irradiation,... view more (1999-11-29)

Discovery confirms explosive prediction made by astrophysicists in 1999
NASA's Swift satellite and ground-based telescopes have discovered the most distant exploding star on record, confirming a 1999 prediction made by University of Chicago astrophysicist Don Lamb and Daniel Reichart, who was then a graduate student at Chicago.   view more (2005-09-13)

Study questions assumptions about human sensitivity to biological motion
Humans may not be any more sensitive in detecting biological motion compared with nonbiological motion, concludes a study recently published in Journal of Vision, an online, free-access publication of the Association for Research in Vision and Ophthalmology (ARVO).   view more (2007-10-18)

FSU chemists using light-activated molecules to kill cancer cells
A key challenge facing doctors as they treat patients suffering from cancer or other diseases resulting from genetic mutations is that the drugs at their disposal often don't discriminate between healthy cells and dangerous ones -- think of the brute-force approach of chemotherapy, for instance.   view more (2007-08-09)

Forget cooking"¦
There are some preferences among the consumers that establish the tendency in the development of new formulations and technologies of food preserving. Those preferences are toward food of easy and rapid preparation, less severely processed (preserving vitamins and nutrients), natural (without... view more (2002-09-24)

Red dust in planet-forming disk may harbor precursors to life
Astronomers at the Carnegie Institution have found the first indications of highly complex organic molecules in the disk of red dust surrounding a distant star.   view more (2008-01-04)
