A new initiative is underway to breathe life back into the 700,000-gallon ocean tank at Biosphere 2. The new ocean at Biosphere 2 will provide a glimpse into the sea that's closest to Southern Arizona – the Gulf of California, which stretches for a thousand miles from the mouth of the Colorado River to Mazatlan on the mainland of Mexico.

The original "ocean" was one of several habitats intended to sustain a crew of scientists living and working inside the Biosphere 2 dome isolated from the outside world. When the "enclosed missions" ended in 1994, the fragile ecology of the ocean habitat collapsed. The corals died and algae and bacterial mats took over, crowding out the reef.  

A genetic study of brown bears (Ursus arctos) in Bulgarian mountain regions showed they originated in Carpathia. So how did they get to Bulgaria? It wasn't natural dispersal. 

Bulgarian and Romanian NGOs, the Frankfurt Zoological Society, and scientists of the Senckenberg Conservation Genetics Section in Frankfurt have found that a legend was probably true - the legend being that the former leader of the Romanian Communist Party, Nicolae Ceausescu, flew the bears to Bulgaria.

PROVIDENCE, R.I. [Brown University] — The surface of Mercury crackled with volcanic explosions for extended periods of the planet's history, according to a new analysis led by researchers at Brown University. The findings are surprising considering Mercury wasn't supposed to have explosive volcanism in the first place, and they could have implications for understanding how Mercury formed.

Despite high rates of contraceptive use, unwanted pregnancies resulting in terminations remain high among young women.

In an article in the April issue of the Australian and New Zealand Journal of Public Health, Danielle Mazza from Monash University, and colleagues, examine the paradox of high rates of contraceptive use, over the counter availability of emergency contraception and unplanned pregnancy.

"The emergency contraceptive pill has been available to women for over-the-counter purchase since 2004," Professor Mazza said.

"Together with high rates of contraceptive use, this should result in lower rates of unplanned pregnancies for Australian women, but it has not.

BUFFALO, N.Y. – Chemotherapeutic drugs excel at fighting cancer, but they're not so efficient at getting where they need to go.

They often interact with blood, bone marrow and other healthy bodily systems.

A team of researchers from the Center for Imaging Science at the Johns Hopkins University and the CMLA of the École Normale Supérieure Cachan have demonstrated new algorithmic technologies for the parametric representation of human shape and form. Coupled with advanced imaging technologies, this presents opportunities for tracking soft-tissue deformations associated with cardiovascular studies, radiation treatment planning in Oncology, and neurodegenerative brain illnesses.
