Beautiful plumage: Feather color and sex start the species revolution

Faculty of 1000, the leading scientific evaluation service, has highlighted research providing evidence for the evolution of a new species. Birds use plumage colour to recognize and select potential mates. A mutation of a single DNA base can lead to a striking colour change, as demonstrated by ...

Knee injuries may start with strain on the brain, not the muscles

ANN ARBOR, Mich.---New research shows that training your brain may be just as effective as training your muscles in preventing ACL knee injuries, and suggests a shift from performance-based to prevention-based athletic training programs. The ACL, or anterior cruciate ligament, is one of the f...

IFAR contributes to study that finds genes that influence the start of menstruation

(Boston, Mass.)Two scientists at the Institute for Aging Research of Hebrew SeniorLife are part of an international team of investigators that has identified genes that influence the start of menstruation, a milestone of female reproductive health that has lifelong influences on overall health. Th...

Genes that influence start of menstruation identified for first time

Researchers from the Peninsula Medical School, along with collaborators from research institutions across Europe and the United States, have for the first time identified two genes that are involved in determining when girls begin menstruation. The work will be published in Nature Genetics this ...

Mothers give interloper's offspring a head start in life

A new study has revealed that mother birds can provide an early advantage to the chicks that they have sired with their non-social partner (known as extra-pair offspring). It has long been known that female birds commonly mate with males other than their social partner, producing broods of mix...

IVCC and Syngenta start project for novel insecticidal active ingredient for malaria control

Improved and sustainable control ...

Viruses, start your engines!

Peering at structures only atoms across, researchers have identified the clockwork that drives a powerful virus nanomotor. Because of the motor's strength--to scale, twice that of an automobile--the new findings could inspire engineers designing sophisticated nanomachines. In addition, because ...

New World post-pandemic reforestation helped start Little Ice Age, say Stanford scientists

The power of viruses is well documented in human history. Swarms of little viral Davids have repeatedly laid low the great Goliaths of human civilization, most famously in the devastating pandemics that swept the New World during European conquest and settlement. In recent years, there has been...

Girls who begin dieting twice as likely to start smoking

GAINESVILLE, Fla. Starting to diet seems to double the odds a teenage girl will begin smoking, a University of Florida study has found. UF researchers, who analyzed the dieting and smoking practices of 8,000 adolescents, did not find the same link in boys, who were also less likely than girls ...

Microbes start immune response by sneaking inside cells

Immune cells that are the body’s front-line defense don’t necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought. In a new paper, University of Michigan scientists describe their findings that bacteria can barge in...

A healthier start to a pig's life

Weaning is a problematic time for pigs, especially in intensive production. Piglets commonly become susceptible to bacterial infections, restricting their growth rate; and often leading to losses of 10% or more. The antibiotics used routinely for many years to control these rapidly-spreading infect...

Air travel and flu: Post-9/11 restrictions delayed start of season

The onset of the flu season in the USA has been shown to be influenced by air travel. After flights were restricted following the 9/11 terrorist attacks in 2001, the flu season started about two weeks later than usual. In both the northern and southern hemispheres, influenza epidemics occur annua...

Human stem cells delay start of Lou Gehrig's disease in rats

Researchers at Johns Hopkins have shown that transplanting human stem cells into spinal cords of rats bred to duplicate Lou Gehrig's disease delays the start of nerve cell damage typical of the disease and slightly prolongs life. The grafted stem cells develop into nerve cells that make substantial...

A new jump start for aging blood vessels

Recent studies show promise for significantly reducing vascular aging by inactivating TNFa, which has been linked to blood vessel dysfunction and cell death. The related report by Csiszar et al., "Vasculoprotective effects of anti-TNFa treatment in aging," appears in the January issue of The Ameri...

When the going gets tough, slime molds start synthesizing

In times of plenty, the uni-cellular slime mold Dictyostelium discoideum leads a solitary life munching on bacteria littering the forest floor. But these simple creatures can perform heroic developmental acts: when the bacterial food supply dries up, Dictyostelium amebas band together with their ne...
