Computer Simulations Key to Less-resistant Antibiotics

October 17, 2014 2:00 pm | by Univ. of Bristol | News | Comments

Scientists have used computer simulations to show how bacteria are able to destroy antibiotics– a breakthrough that will help develop drugs that can effectively tackle infections in the future. It’s hoped this insight will help scientists to develop new antibiotics with a much lower risk of resistance, and to choose the best medicines for specific outbreaks.

Physicists: Leave Your Nails Alone

October 17, 2014 2:00 pm | by Institute of Physics | News | Comments

The daily trimming of fingernails and toenails to make them more aesthetically pleasing could be detrimental and potentially lead to serious nail conditions. This is according to researchers who have devised equations to identify the physical laws that govern nail growth, and used them to throw light on the causes of some of the most common nail problems, such as ingrown toe nails, spoon-shaped nails and pincer nails.

Ancient Mountains Fed Early Life

October 17, 2014 7:00 am | by The Australian National Univ. | Videos | Comments

Scientists have found evidence for a huge mountain range that sustained an explosion of life on Earth 600 million years ago. The mountain range was similar in scale to the Himalayas and spanned at least 2,500 kilometers of modern west Africa and northeast Brazil, which at that time were part of the supercontinent Gondwana.

Nanoflares May Heat the Sun's Corona

October 17, 2014 7:00 am | by Harvard-Smithsonian Center for Astrophysics | News | Comments

Why is the Sun's million-degree corona, or outermost atmosphere, so much hotter than the Sun's surface? This question has baffled astronomers for decades. Now, a team has found that miniature solar flares called nanoflares— and the speedy electrons they produce— might partly be the source of that heat, at least in some of the hottest parts of the Sun's corona.
