Scientists use manufacturing methods to reconstruct mastodon

...ed exhibit will showcase Fisher's contributions to understanding how mastodons lived, died and became extinct some 10,000 years ago. Using evidence from tusks, bones, excavation sites and comparisons with other Ice Age animals, Fisher has made some surprising discoveries. While excavating an 11,000-year-old mastod...

Scientists find viruses can't stick to sea bugs in the dark

... Jia hopes that the research will lead to a better understanding of the relationship between phage and cyanobacteria and so the health of the seas, but may also eventually lead to efficient methods of controlling cyanobacteria blooms in an environmentally friendly way, by using these natural viruses. ...

Lipids get new comprehensive classification system

Understanding how bacteria communicate may help scientists prevent disease

...small RNA. Modeling the circuit will be crucial in understanding how it functions and integrates signals from multiple inputs," Kulkarni said. A third question is how the circuit regulates important biological processes, such as biofilm formation and virulence. "Biofilms make bacteria resistant to antibiotics, so...

Antiretroviral Therapy May Prevent HIV Transmission From Breastfeeding Mothers To Infants

... studies are of vital importance for both biologic understanding and health policy. In the United States and other settings where HIV-infected mothers can safely avoid breastfeeding, the rate of mother-to-child transmission can be reduced to 1 percent or less. The goal in resource-limited settings, where HIV-infec...
