Researchers working to improve durability in fuel cell powered buses have discovered links between electrode degradation processes and bus membrane durability. The team is quantifying the effects of electrode degradation stressors in the operating cycl… Continue reading →
Suicide risk is higher among military personnel with more lifetime TBIs, even after controlling for clinical symptom severity. Results of the study show that multiple TBIs, which are common among military personnel, may contribute to increased risk for… Continue reading →
Males that spend all their time reacting to their rivals die earlier and are less able to mate later in life according to new research. It reveals how fruit flies that are subjected to continual competition from mating rivals, mate for longer and produce more offspring in early life. But they pay a high price – a shorter lifespan and reduced mating ability later in life. Continue reading →
Why do some memories last a lifetime while others disappear quickly? A new study suggests that memories rehearsed, during sleep or waking, can have an impact on memory consolidation and on what is remembered later. A new study shows that when the infor… Continue reading →
An air-breathing bio-battery has been constructed by researchers from Poland. The core element providing the new power source with relatively high voltage and long lifetime is a carefully designed cathode taking up oxygen from air and composed of an en… Continue reading →
A transplanted kidney has a finite life expectancy because it often becomes the target of the recipient’s immune system, which may mount antibodies that attack the organ. Because there is a critical need to extend the life of transplanted organs — esp… Continue reading →
Research indicates that half of all lifetime cases of mental illness begin by age 14, well before adulthood. Three new studies investigate the cognitive, genetic and environmental factors that may contribute to mental health disorders in adolescence. Continue reading →
Studies at the U.S. Department of Agriculture are shedding some light on the microbes that dwell in cattle manure — what they are, where they thrive, where they struggle, and where they can end up. Continue reading →
Older bilinguals expend less energy when performing a cognitive flexibility task. The findings suggest the value of regular stimulating mental activity across the lifetime. As people age, cognitive flexibility — the ability to adapt to unfamiliar or u… Continue reading →
Researchers have found new evidence that metabolic stress can increase the onset of atrial arrhythmias, such as atrial fibrillation, a common heart condition that causes an irregular and often abnormally fast heart rate. The findings may pave the way f… Continue reading →
Scientists are able to use a new technique to produce three-dimensional images of breast tissue that are two-to-three times sharper than current hospital CT scanners, and with a lower dose of X-ray radiation than from a mammogram. With higher quality i… Continue reading →
If you are overweight and pregnant, your baby isn’t destined to become obese, according to a research report. The report shows that modifying fat intake during pregnancy to a moderate level benefits the child regardless of the mother’s size. Specifical… Continue reading →
Rechargeable batteries are no doubt an investment. The upfront cost makes those $5 single-use batteries seem much more appealing.
But despite the price, The National Electrical Manufacturers Association has estimated that U.S. demand for rechargeables is growing twice as fast as demand for non-rechargeables.
Just how high is that demand? More than 350 million rechargeable batteries are [...] Continue reading →
