Stem cells used to model infant birth defect
Stem cells
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.

Some bullies are just the shy type: A darker side to social anxiety disorder
Psychology
When you think of people suffering from social anxiety, you probably characterize them as shy, inhibitive and submissive. However, new research suggests that there is a subset of socially anxious people who act out in aggressive, risky ways—and that their behavior patterns are often misunderstood.

Cat-calls are detrimental to everyone
Animal Behavior
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.
