New tooth enamel dating technique could help identify disaster victims

...he enamel dating technique doesn't work for people born before 1943, because all of their teeth would have been formed before testing began in 1955. In their Nature paper, Buchholz and his colleagues note that the technique for carbon-14 analysis using accelerator mass spectrometry is becoming increasing...

Exercise aside, genes may ultimately dictate seniors' mobility

...healthier than their couch potato peers, but those born with a certain gene benefited the most from physical activity, said Marco Pahor, M.D., director of University of Florida's Institute on Aging and the multi-institutional study's senior author. "To our knowledge, this is the first study to show behav...

Promising therapies for haemophilia & heart disease

...ng 'bleeds'. About one in 6000 Australian males is born with haemophilia in severe, moderate or mild form. People with haemophilia rely on intravenous infusion of recombinant Factor VIII clotting protein. Professor Denisa Wagner and her Harvard colleagues have made ground-breaking discoveries that provid...

Israeli scientists successfully transplant frozen-thawed ovaries in sheep

...anting thawed ovarian tissue. Two babies have been born using this technique[3]. However, adhesions and the loss of blood to the ovarian follicles that occurs during the interval before new blood vessels are being formed, remain major obstacles. The first aim of the Israeli team was to test in vitro whet...

UCLA researchers identify key enzyme linked to childhood blindness

...e discovered that RPE65, a gene missing in infants born with the blinding disease Leber congenital amaurosis, is also a key enzyme in the visual cycle. The identity of this enzyme has long been a mystery to scientists. The study, "Rpe65 is the Retinoid Isomerase in Bovine Retinal Pigment Epithelium," is ...

Scientists find evidence of catastrophic sand avalanches, sea level changes in Gulf of Mexico

Studying genetic differences in twins may give Plass and his colleagues insight into how methylation is regulated. "One would expect identical twins to develop and express genes at the same levels, but in fact this ch...

Researchers discover new route to hemoglobin synthesis

Opiates appear to better "ameliorate the withdrawal, facilitate feeding and potentially reduce the likelihood of seizures," according to two new systematic reviews done by David Osborn, a neonato...

Opiates Better Than Sedatives For Treating Newborns In Withdrawal

Brain size may depend upon how neural cells are cleaved

...e of the brain," said Tsai. "And, there are humans born with too few neurons, called microcephaly, or too many neurons, called macrocephaly. I would speculate that many of these cases are the outcome of some sort of impairment in the regulation of cell division, perhaps in the plane of division," said Tsa...

Expanding forests darken the outlook for butterflies, study shows

...o not generally travel beyond the meadows they are born in, and the shrinking meadows could lead to inbreeding and the decreased diversity in the gene pool, Roland said. "In general, inbreeding leads a species to be more vulnerable to a variety of mortality factors that lower survival rates," Roland expl...

Engineered molecule amplifies body's immune response

...uri. "This also applies to Stat1. Children who are born with genetic deficiencies of Stat1 are also very susceptible to infection. In the more severe case, the children die in infancy of fatal viral infections. In less severe cases, they later develop infections due to mycobacteria. When interferon levels...

For first time, brain cells generated in a dish

In people, stem cells develop naturally into full-fledged brain cells as they travel through a neural pathway that begins deep within the brain in a region called the sub...

Redesigned protein accelerates blood clotting

...dministered by injection, but one quarter of those born with no factor VIII suffer severe immune reactions that render the treatment inactive. In addition, current treatment costs as much as $200,000 per patient per year. Researchers at the University of Rochester Medical Center have been studying the str...

After completing graduate work at the University of California, Waksman joined the Rutgers faculty in 1918. Even as an undergraduate stude...
