Researchers found a near-100% loss of hatchlings due to predation and lack of migration between two forest preserves. The study suggests genetic isolation and potential extinction threats for the Illinois population.
Scientists found that genetically-engineered oilseed rape produces hybrid, transgenic weeds resistant to herbicides, which reproduce as prolifically as unaltered weeds. These weeds may carry beneficial traits from the crop parent and still exhibit weed-like characteristics.
Temple University Hospital has introduced the internal jaw distraction device DynaForm, which helps regrow destroyed bone and correct facial deformities. The device is less cumbersome than traditional methods and can be used as an alternative to painful extraction for severe tooth crowding.
A decline in deaths from congestive heart failure (CHF) has been observed among older adults in the US between 1988 and 1995. The greatest drop was seen in black adults, likely due to improved treatment strategies advocated by the American Heart Association, including earlier identification and better medication adherence.
A recent study found that chronically ill children are more likely to experience poor adjustment, including hostility or withdrawal, regardless of the illness type. The researchers controlled for social and economic factors but still observed a significant difference between chronically ill and healthy children.
A University of Florida study reveals that zinc supplements can increase the levels of genetic material in human immune cells, providing immediate protection against disease and stress. The research found a rapid response to zinc supplementation, with RNA levels increasing three times within 24 hours.
Biological clocks in animals and plants regulated by temperature rather than light, according to Dartmouth study. Temperature cycles may be crucial for maintaining circadian rhythm in humans, particularly during seasonal changes.
