In unprecedented space research, DuPont scientists have attained a significant scientific accomplishment regarding the future development of soybeans – one of the most consumed crops in the world today.
During a research mission that concluded with the return of Space Shuttle Atlantis Friday, soybean seeds planted and nurtured by DuPont scientists germinated, developed into plants, flowered, and produced new seedpods in space. The 97-day growth research initiative is the first-ever to compl
Sexual reproduction has many advantages — some most pleasurable — and probably leads to the long-term survival of the species concerned. During the formation of reproductive cells or gametes, sexual reproduction is accompanied by an exchange of genes between the two chromosomes inherited from the parents. Each individual arising from these gametes thus receives a veritable mosaic of parental and grandparental characteristics, and so at one and the same time resembles and differs from the parents.
Low levels of folic acid in plasma have been associated with an increased risk of miscarriage in a study published in Journal of the American Medical Association lately. On the other hand, no connection was found between high levels of folic acid and increased risk of miscarriage.
In the US folic acid is added to flour to prevent pregnant women from developing a deficit of folic acid. Previous studies have shown that both deficits and surpluses of folic acid can heighten the risk of miscarri
People who find it hard to lose all the weight they want or that their doctors recommend should take heart, a University of North Carolina at Chapel Hill scientist says. New research suggests that losing even modest amounts of weight can pay off in better health.
The study showed for the first time that shedding excess pounds decreases activity of a key enzyme known to play a central role in high blood pressure, said Dr. Joyce Harp, associate professor of nutrition and medicine at the UNC s
A new company is helping to solve a 20-year problem in the chemicals industry.
Enviresearch, a Newcastle University ‘spin-out’, uses computer models to determine whether chemicals are environmentally friendly.
The British Government demands that chemicals undergo a rigorous testing programme, including an ‘environmental risk assessment’, before it is satisfied a substance is safe. Only then will it grant a sales licence for the UK and Europe.
Due to these strict regulations,
UCSF-led researchers have developed a highly sensitive, automated test for detecting prions (PREE-on) that they report significantly improves the accuracy and speed of detecting the various forms of the infectious agent, which causes a set of neurodegenerative diseases, in cattle, sheep, deer and elk.
Because the test is automated, the researchers say, it could be used for high-throughput testing of brain samples of cattle with bovine spongiform encephalopathy (BSE), or “mad cow” disease, a
