Hemangiomas - strawberry-like birthmarks that commonly develop in early infancy – are generally harmless, but up to 10 percent cause tissue distortion or destruction and sometimes obstruction of vision or breathing. Since the 1960s, problematic hemangiomas have been treated with corticosteroids such as dexamethasone or prednisone.

For every woman who is a direct target of sexism, there are others who witness the event and are also affected. The actions of one sexist man affect how female bystanders feel and behave towards men in general. Stephenie Chaudoir and Diane Quinn, from the University of Connecticut in the US, publish their work1 on the effects of bystander sexism and group-level reactions to sexism in Springer's journal Sex Roles.

Butterflies are emerging in spring over 10 days earlier than they did 65 years ago, a shift that has been linked to regional human-induced climate change in a University of Melbourne- led study. The work reveals for the first time, a causal link between increasing greenhouse gases, regional warming and the change in timing of a natural event.

Graphene—carbon formed into sheets a single atom thick—now appears to be a promising base material for capturing hydrogen, according to recent research* at the National Institute of Standards and Technology (NIST) and the University of Pennsylvania. The findings suggest stacks of graphene layers could potentially store hydrogen safely for use in fuel cells and other applications.
