Pumpkin skin may scare away germs

The skin of that pumpkin you carve into a Jack-o'-Lantern to scare away ghosts and goblins on Halloween contains a substance that could put a scare into microbes that cause millions of cases of yeast infections in adults and infants each year, according to a new study in the current issue of ACS' Journal of Agricultural and Food Chemistry.

Remotely operated vehicles and satellite tags aid turtle studies

Researchers are using a remotely operated vehicle and satellite-linked data loggers to learn more about turtle behavior in commercial fishing areas and to develop new ways to avoid catching turtles in fishing gear. This marks the first time an ROV has been used to follow turtles in the wild to learn about their behavior and how they interact with their habitat

Researchers find room design can enhance patient care

Children can tolerate the stress of surgery when they are fed until two hours before surgery, because there was no difference regarding stomach residue and metabolic changes among patients that underwent surgery after fasting for short and long periods. There is no need for more than two hours of fasting before inguinoscrotal region surgery. Further studies in surgical patients should help to...

Stanford scientists turn stem cells into precursors for sperm, eggs

Human embryonic stem cells derived from excess IVF embryos may help scientists unlock the mysteries of infertility for other couples struggling to conceive, according to new research from the Stanford University School of Medicine. Researchers at the school have devised a way to efficiently coax the cells to become human germ cells -- the precursors of egg and sperm cells -- in the laboratory.

Statins show dramatic drug and cell dependent effects in the brain

A study in the October Journal of Lipid Research finds that similar statin drugs can have profoundly different effects on brain cells -- both beneficial and detrimental. These findings reinforce the idea that great care should be taken when deciding on the dosage and type of statin given to individuals, particularly the elderly.
