Females of all ages are less active than their male peers. Two studies, presented today (Tuesday 6 January) at a major academic conference, reveal the gender difference in activity levels among school children and the over 70s. Both studies show males to be more physically active than females.

Viagra's other talents: Help a 'signaling' protein shield the heart from high blood pressure damage

Tweet

Johns Hopkins and other researchers report what is believed to be the first direct evidence in lab animals that the erectile dysfunction drug sildenafil amplifies the effects of a heart-protective protein.

The team's findings, to be published in the Journal of Clinical Investigation online Jan. 5, helps explain why sildenafil, more widely known as Viagra, has already been shown to improve heart function and may one day have value in either treating or preventing heart damage due to chronic high blood pressure.

Study: Can nature's leading indicators presage environmental disaster?

Tweet

MADISON — Economists use leading indicators — the drivers of economic performance – to take the temperature of the economy and predict the future.

Now, in a new study, scientists take a page from the social science handbook and use leading indicators of the environment to presage the potential collapse of ecosystems. The study, published today (Jan. 5) in the Proceedings of the National Academy of Sciences by two ecologists and an economist, suggests it may be possible to use nature's leading indicators to avert environmental disaster.
