Lifelong exercising yields sensational results

Senior active skiers have twice the oxygen-uptake capacity of seniors who do not exercise. "The findings show that humans have a great potential to maintain a high level of physical work capacity and thereby better quality of life even at advanced ages," says a professor of sports...

Mixed-use neighborhoods reduce some violent crimes, study says

Mixed-use neighborhoods that combine residential and business development may help lead to lower levels of some types of violent crime, a new study suggests. The results were just as true in impoverished neighborhoods as they were in more affluent areas, offering one possible way of improving blighted areas, according to the...

New Therapy Found For Lung And Skin Cancer, Based On Suicide Gene E

Scientists have developed a new therapy for the treatment of skin and lung cancer. This therapy involves the use of a suicide coliphage-gene (gene E) that can induce death to cells transfected with it. Their studies have demonstrated that this technique is not only effective in vitro (using tumour cell cultures), but also in vivo through the use of experimental animals in which tumours were...

Political connections linked to corporate corruption

While most citizens recognize that corruption is "bad," the average citizen is unaware of the benefits enjoyed by politically connected firms, or how common government favors are worldwide. In the US, many citizens were outraged at the provision and size of bailouts for "too big to fail" banks. A new study claims that not only does corruption exist in the corporate world, but that political...

Progress toward terabit-rate high-density recording

Next-generation high-density storage devices may keep more than 70 times the contents of the entire US Library of Congress on a single disc -- but only if that data can be written quickly enough. Researchers have now demonstrated a way to record onto ferromagnetic films thirty times faster than today's...

Research sheds light on altruism

Using digital evolution techniques that give scientists the ability to watch evolution in action, researchers have shed new light on what it is that makes species altruistic.

Rice growers turn to computer for advice, predictions

Figuring out how a rice crop was faring used to be a head-scratching exercise with predictably unpredictable results. But now a few punches on a keyboard can yield a pretty close forecast for a rice crop and tell a farmer what changes could improve the outcome at harvest.

Silent electric vehicles made safer

A little green van called ELVIN is whizzing around the University of Warwick as part of a major research project aimed at tackling the safety issues linked to the lack of sound from electric vehicles.

Spare the rod, spoil the child?

Grabbing a child firmly by the arm, yelling and repeatedly punishing him or her may not be without long-terms risks, according to researchers. They are studying how this harsh parenting can impair the emotional development of a child, possibly leading to anxiety disorders such as social phobia, separation anxiety and panic...

Ultrashort laser ablation enables novel metal films

Laser ablation is well known in medical applications like dermatology and dentistry, and for more than a decade it has been used to vaporize materials that are difficult to evaporate for high-tech applications like the deposition of superconductors. Now researchers have studied the properties of femtosecond laser ablation plumes to better understand how to apply them to specialized...

US residents outperformed staff physicians on four of nineteen measures of quality

Research on the quality of US resident physician performance levels has often been limited by lack of a comparison group or strict focus on specific diseases and geographical areas. In order to gain insight on differences in quality of care provided by resident physicians versus staff physicians, researchers investigated performance of physicians in 33,900 hospital-based outpatient visits...

Watching electrons move in real time

A new article describes the emerging technique of X-ray powder diffraction, which has been used to map the movement of electrons in real time and to observe a concerted electron and proton transfer that is quite different from any previously known phase transitions in the model crystal, ammonium...
