They may never win an Oscar, but scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed techniques for creating accurate movies of biological and chemical molecules, a feat only theorized up until now.

Two global research organizations dedicated to designing a vaccine against HIV – the International AIDS Vaccine Initiative (IAVI), and the Center for HIV/AIDS Vaccine Immunology (CHAVI) – have signed an agreement to work together to address major biological questions that have slowed development of a safe, effective and affordable AIDS vaccine.

With major implications for long-duration space travel, a study from the Lombardi Comprehensive Cancer Center at Georgetown University Medical Center demonstrates that the high-energy radiation found in space may lead to premature aging and prolonged oxidative stress in cells. The findings suggest that astronauts may be at increased risk of colon cancer due to exposure to the high linear energy transfer (LET) radiation found in space.

Annual flu vaccinations are highly effective at preventing acute respiratory illness and making sure that existing breathing problems don’t get any worse, according to research published in the April issue of IJCP, the UK-based International Journal of Clinical Practice.

Half a century after the last earth-shattering atomic blast shook the Pacific atoll of Bikini, the corals are flourishing again. Some coral species, however, appear to be locally extinct.

An investigation of the genes that govern spore formation in the bacteria B. subtilis shows that chance plays a significant role in determining which of the microbes sacrifice themselves for the colony and which go on to form spores.

As well as cutting our fossil fuel emissions, planting new forests, or managing existing forests or agricultural land more effectively can capitalise on nature’s ability to act as a carbon sink. Research published online in the open access journal Carbon Balance and Management shows that although planting trees alone is unlikely to solve our climate problems, large-scale plantations could have a significant effect in the longer term.
