The world's tiniest nuclear genome appears to have "snipped off the ends" of its chromosomes and evolved into a lean, mean, genome machine that infects human cells, according to new research.

The ability to understand emotions is a key ingredient in people who become leaders in groups with no formal authority, a new paper has found.
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...
Children whose families own dogs are more active than those without, according to new research.
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...
For decades scientists believed Neanderthals developed "modern" tools and ornaments solely through contact with Homo sapiens, but new research now shows these sturdy ancients could adapt, innovate and evolve technology on their own.
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...
"Yeah, I'm on my way home." "That's funny." "Uh-huh." "What? No! I thought you were -- " "Oh, OK." Listening to someone talk on a cell phone is very annoying. A new study finds out why: hearing just one side of a conversation is much more distracting than hearing both sides and reduces our attention in other...
New research shows the extent to which such sustained winds can dramatically lower water levels. The research suggests that such a "wind setdown" event could have led to a parting of waters similar to the description in the biblical account of the Red Sea.
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...
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...
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.
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.
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.
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...
As the United States prepares for the upcoming flu season, a group of researchers continues to model how H1N1 may spread.
In order for targeted therapies against cancer to be effective, scientists need to understand upfront what related proteins in a signaling "network" makes a cancer cell resistant to a drug and selectively target them as well, say researchers.
In the complex world of ant-plant partnerships, serial monogamy can help trees maximize their evolutionary fitness, a new study shows.
Man has profited enormously from his ability to domesticate animals. Animals need training to perform particular tasks but until recently the effects of training on the animals concerned had hardly been considered. Researchers now presents a study of the stress caused to horses by being ridden for the first...
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...
Scientists have discovered evidence of "universal ubiquitous magnetic fields" permeating deep space between galaxies since the time of the Big Bang.
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...
Three-year data demonstrated that satisfactory clinical and safety outcomes of sirolimus eluting stents with a biodegradable polymer were sustained in a real world setting.
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...
Shopping on the Internet or working from home could be increasing carbon emissions rather than helping to reduce them, a new report claims. The research reveals that people who shop online must order more than 25 items otherwise the impact on the environment is likely to be worse than traditional...
