There remains a lack of consensus amongst the medical and scientific communities about any cancer risk from low level radiation, particularly low-dose radiation delivered from computed tomography (CT) scans. However, the study of epigenetics may play a role in determining whether or not future trends of diseases can in fact be linked to utilization of CT, according to an article in the February issue of the Journal of the American College of Radiology (JACR).

Researchers have made a breakthrough in HIV research that had eluded scientists for over 20 years, potentially leading to better treatments for HIV, in a study published today in the journal Nature.

Efforts will begin this year to expand the Gishwati National Conservation Park in Rwanda by 21 percent and begin the development of a 30-mile (50 km) forest corridor to Nyungwe National Park for a group of 14 chimpanzees facing extinction. Organizers of the Gishwati Area Conservation Program (GACP) say that in 2010 they will fund reforestation of 647 acres (262 hectares) in the Kinyenkanda area of Rutsiro District in Rwanda's Western Province.

Researchers writing in the February issue of BioScience propose reintroducing small, managed populations of wolves into national parks and other areas in order to restore damaged ecosystems. The populations would not be self-sustaining, and may consist of a single pack. But the BioScience authors suggest that even managed populations could bring ecological, educational, recreational, scientific, and economic benefits.

In 2009, soybeans represented an almost $30 billion industry in the U.S. alone, making soybeans the second-most profitable crop next to corn. Worldwide, soybeans have been used in human foods and livestock feed for centuries and have been a key component in industrial products, such as plastics and soy biodiesel, an environmentally friendly fuel. A team of researchers, including University of Missouri researchers, recently completed a study identifying 1.1 million base pairs of DNA in the soybean genome, including more than 90 distinct traits that affect plant development, productive characteristics, disease resistance, seed quality and nutrition, which could lead to extensive crop improvements.
