Climate scientists have long recognized the importance of forest conservation and forest regrowth in climate mitigation and carbon sequestration -- capturing carbon dioxide (CO2) from the atmosphere. But the detailed information required to make accurate estimates of this potential has remained elusive.

Now, an international team of 60 scientists, working together as the 2ndFOR Network, has completed studies on the effects of forest conservation and secondary forest regeneration across 43 regions in Latin America.

Why does delaying bedtime create chronic sleepiness?

We may be creeping a little closer to knowing, thanks to a paper on fruit flies in Cell. 
Fruit flies have sleep remarkably similar to people and researchers say they found a group of brain cells in charge of so-called sleep drive that becomes more active the longer flies are kept awake. The same mechanism, they say, also plays a role in putting the flies to sleep and keeping them that way.

EAST LANSING, Mich. -- People with intellectual disabilities are more susceptible to exploitation and abuse, and the rise of the Internet only increases their vulnerability.

A first-of-its-kind study co-authored by a Michigan State University scholar finds that adults with Williams syndrome -- who are extremely social and trusting -- use Facebook and other social networking sites frequently and are especially vulnerable to online victimization.

Roughly a third of study participants said they would send their photo to an unknown person, arrange to go to the home of a person they met online and keep online relationships from their parents.

Summary:

Professional athletes suffer from sleep disorders more frequently than generally thought, however, systematic examination, counselling and individual treatment planning can improve the quality of their sleep. Published in the Journal of Sports Sciences, a new Finnish study clearly shows for the first time that systematic measures can improve the sleep of professional athletes.

The results of a new survey published in ecancermedicalscience indicate that a majority of oncology professionals believe that writing condolence letters to the families of deceased patients is an important component of cancer palliative care.

The study explored whether institutions should consider changing policies to raise condolence letters to a more official standing.

But because this practice is a personal grace note, it has rarely been studied or discussed. In particular, this issue hasn't been researched in the UK, where cultural practices surrounding grief are often private.
