Weapon performance determines mating success in the collared lizard

In territorial species with polygynous mating systems, reproductive success reflects phenotypic variation. At the gross level, such phenotypic variation can include that of body size and weapon morphology, as well as of weapon function and performance. In a study published in the September issue of The American Naturalist, A. Kristopher Lappin (Northern Arizona University) and Jerry F. Hus...

Confidence in memory performance helps older adults remember

Believing that you can retain a good memory even in your twilight years is the first step to achieving that goal. Those who believe they can control their memory are more likely to employ mnemonic strategies that help keep memory fit despite the march of time. These are the conclusions of a new Brandeis study published in the Journals of Gerontology: Psychological Sciences. The study demon...

Man-made heart tissue improves cardiac performance

Researchers have developed a method to engineer blood vessels within the tissue of previously engineered heart muscle. Trials have resulted in significant improvement in heart function. The study is published in the journal Artificial Organs. With heart disorders affecting individuals globally and contributing to increasing mortality rates, there has been a need to develop new treatmen...

Viagra improves high altitude exercise performance up to 45% for some

Sildenafil (Viagra) significantly improved the cardiovascular and exercise performance measures of trained cyclists at high altitude, mostly because the drug helped some participants improve a lot -- up to 45% -- while others showed little change. Sildenafil provided no benefit at sea level. Ten cyclists who took sildenafil at altitude collectively lowered the time it took to cover six kil...

Poor athletic performance linked to vitamin deficiency

Active individuals lacking in B-vitamins ?including college athletes and other elite competitors -- may perform worse during high-intensity exercise and have a decreased ability to repair and build muscle than counterparts with nutrient-rich diets, according to recent Oregon State University research published in the International Journal of Sport Nutrition and Exercise Metabolism. The B-v...

Mysterious 'neural noise' actually primes brain for peak performance

Researchers at the University of Rochester may have answered one of neuroscience's most vexing questions--how can it be that our neurons, which are responsible for our crystal-clear thoughts, seem to fire in utterly random ways? In the November issue of Nature Neuroscience, the Rochester study shows that the brain's cortex uses seemingly chaotic, or "noisy," signals to represent the ambigu...

Growth hormone to boost athletic performance risks diabetes

Use of growth hormone to boost athletic performance can lead to diabetes, reports a study published ahead of print in the British Journal of Sports Medicine. He had lost 40 kg in 12 months, during which he had also experienced excessive urination, thirst, and appetite...

Sleep disturbances affect classroom performance

As a night of bad sleep can have an adverse effect on an adult’s performance at work the next day, an insufficient amount of rest can also have a negative impact on how well middle or high school students perform in the classroom. A study published in the February 15th issue of the Journal of Clinical Sleep Medicine (JCSM) finds that adolescents who experience sleep disturbances are more likely...

Individual differences in a clock gene predict decline of performance during sleep deprivation

People are known to differ markedly in their response to sleep deprivation, but the biological underpinnings of these differences have remained difficult to identify. Researchers have now found that a genetic difference in a so-called clock gene, PERIOD3, makes some people particularly sensitive to the effects of sleep deprivation. The findings, reported by Antoine Viola, Derk-Jan Dijk, and colle...
