*One youngster only six times heftier than Jupiter*

TORONTO, ON – A University of Toronto-led team of astronomers has discovered over two dozen new free-floating brown dwarfs, including a lightweight youngster only about six times heftier than Jupiter, that reside in two young star clusters. What’s more, one cluster contains a surprising surplus of them, harbouring half as many of these astronomical oddballs as normal stars.

“Our findings suggest once again that objects not much bigger than Jupiter could form the same way as stars do. In other words, nature appears to have more than one trick up its sleeve for producing planetary mass objects,” says Professor Ray Jayawardhana, Canada Research Chair in Observational Astrophysics at the University of Toronto and leader of the international team that made the discovery.

AUSTIN, Texas — An international team of scientists that includes two University of Texas at Austin researchers has found that Ecuador’s Yasuní National Park, which sits on top of massive reserves of oil, is in the single most biodiverse region in the Western Hemisphere.

The announcement is part of a final push for the Yasuní-ITT Initiative at the United Nations General Assembly. The initiative proposes that Ecuador receive compensation for half of the revenues the nation would lose by protecting the estimated 846 million barrels of oil that lie beneath the forest. (more…)

The Woods Hole Oceanographic Institution (WHOI) has signed a $1.18 million agreement with the Flatley Discovery Lab in Charlestown, Mass., to investigate and supply marine microbial extracts as possible treatments for cystic fibrosis (CF).

The life-shortening respiratory disease has eluded attempts at a cure, although researchers have been successful in some cases at adding years to a person’s lifespan, primarily through treatment with antibiotics. (more…)

Research gives insight into 50-year-old mystery – zinc important for learning and memory

TORONTO, ON – Zinc plays a critical role in regulating how neurons communicate with one another, and could affect how memories form and how we learn. The new research, in the current issue of Neuron, was authored by Xiao-an Zhang, now a chemistry professor at the University of Toronto Scarborough (UTSC), and colleagues at MIT and Duke University.

COLUMBUS, Ohio – A new study reveals how the delay computer users sometimes experience when making video calls over the internet can actually help communication in some circumstances, even though it is frustrating in many others.

Researchers found that when two strangers first talked about an emotionally charged topic over a video connection with a one-second delay, they actually reported less frustration than did those who talked with no delay. (more…)
