New malaria enzyme laid bare with help of computer calculations
Using only computers, a research team at Uppsala University in Sweden has managed to reveal both the structure and the function of a newly discovered enzyme from the most dangerous malaria parasite, Plasmodium falciparum. All that was needed was the amino acid sequence of the enzyme. The findings... view more (2004-12-07)

Violent video games leave teenagers emotionally aroused
A new study has found that adolescents who play violent video games may exhibit lingering effects on brain function, including increased activity in the region of the brain that governs emotional arousal and decreased activity in the brain's executive function, which is associated with control,... view more (2006-11-29)

ISU psychologists produce first study on violence desensitization from video games
Research led by a pair of Iowa State University psychologists has proven for the first time that exposure to violent video games can desensitize individuals to real-life violence.   view more (2006-07-31)

Transistor laser functions as non-linear electronic switch, processor
The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and permit its use as a dual-input, dual-output, high-frequency signal processor.   view more (2006-02-07)

An apparent discrepancy in the Big Bang theory of the universe's evolution has been reconciled by astrophysicists examining the movement of gases in stars.   view more (2006-10-27)

Forecasting the Next Great San Francisco Earthquake
The San Francisco Bay region has a 25 percent chance of a magnitude 7 or greater earthquake in the next 20 years, and a roughly 1 percent chance of such an earthquake each year, according to the "Virtual California" computer simulation.   view more (2005-10-14)

'Computer-chemistry' yields new insight into a puzzle of cell division
Duke University biochemists aided by Duke computer scientists and computational chemists have identified the likely way two key enzymes dock in an intricate three-dimensional puzzle-fit to regulate cell division.   view more (2005-12-09)

Violent video games lead to brain activity characteristic of aggression, MSU researcher shows
A Michigan State University researcher and his colleagues have shown that playing violent video games leads to brain activity pattern that may be characteristic for aggressive thoughts.   view more (2005-10-12)

The mechanics of foot travel
Despite having the bones and muscles to perform a variety of gaits, human beings have developed an overwhelming preference for just two: walking and running.   view more (2005-09-19)

Ultrafast star escapes black hole
Galactic nuclei are the cores of galaxies, groups of thousands to millions of stars that are held together by gravity. As stars in the nucleus are so close together, interactions readily occur.   view more (2006-10-05)

Cracking the genetic code for control of gene expression
Molecular biologists, developmental biologists and computer scientists at the Universtity of Helsinki, Finland, came together to advance towards cracking the code for how gene expression is controlled.   view more (2006-01-13)

Quantum computer solves problem, without running
By combining quantum computation and quantum interrogation, scientists at the University of Illinois at Urbana-Champaign have found an exotic way of determining an answer to an algorithm - without ever running the algorithm.   view more (2006-02-23)

Study provides new insights into brain organisation
Scientists have provided new insights into how the brain is organised-knowledge which could eventually inform diagnosis of and treatments for conditions like Alzheimer's Disease and autism.   view more (2006-08-02)

'Quasicrystal' metal computer model could aid ultra-low-friction machine parts
Duke University materials scientists have developed a computer model of how a "quasicrystal" metallic alloy interacts with a gas at various temperatures and pressures.   view more (2005-09-16)

In an important step toward accelerating drug discovery, researchers have created computer models of more than 900 cell receptors from a class of proteins known to be important drug targets.   view more (2006-02-17)

NIST demonstrates better memory with quantum computer bits
Physicists at the National Institute of Standards and Technology (NIST) have used charged atoms (ions) to demonstrate a quantum physics version of computer memory lasting longer than 10 seconds-more than 100,000 times longer than in previous experiments on the same ions.   view more (2005-08-11)

Scientists crack genetic secrets of human egg
The human egg's ability to transform into a new life, or into new cells that may someday save lives, is well documented. The mystery lies in the mechanics-in how a single cell can transform so nimbly.   view more (2006-09-06)

Breakthrough in computer chip design eliminates wires in data transmission
Research slated to appear in the October 2 edition of the Optical Society of America's (OSA) Optics Express will unveil that researchers have created a new laser-silicon hybrid computer chip that can produce laser beams that will make it possible to use laser light rather than wires to send data... view more (2006-09-21)

New research detects human-induced climate change at a regional scale
Canadian and British climate scientists have clearly detected human-induced climate change at a regional scale in Canada, southern Europe and China.   view more (2006-09-22)

Have you ever seen an elephant...run?
If an elephant is thundering towards you at 15mph you are probably not too concerned with the finer points of biomechanics or the thorny question about whether they are truly running or not.   view more (2006-08-21)

Toward a quantum computer, one dot at a time
