Researchers have successfully repaired damaged mouse hearts using a protein from zebrafish. They discovered that the protein Hmga1 plays a key role in heart regeneration in zebrafish. In mice, this protein was able to restore the heart by activating dormant repair genes without causing side effects, such as heart enlargement. This study marks an important step toward regenerative therapies to prevent heart failure.

Recognizing that news coverage may have influence in forming attitudes and in driving action, a team of psychology researchers examined whether reframing this gender gap in terms of 'men's overrepresentation' -- rather than as 'women's underrepresentation' -- would have an impact on perceptions of the issue and on motivations to address it. Its findings showed that framing the gap as 'men's overrepresentation' -- as opposed to 'women's underrepresentation' -- in political leadership elicited more anger at the disparity among women and increased perceptions that the gap is unjust. Moreover, the results showed that anger at the disparity leads women to take action to address it.
