Different psychosocial factors predict adoption, maintenance of physical activity program

Tweet

PROVIDENCE, RI – The health benefits of regular physical activity are well documented, yet only 32 percent of adults in the United States engage in regular exercise. Now a new study by researchers at The Miriam Hospital offers some new insight into the role of social and environmental influences on physical activity behaviors.

Silencing a protein could kill T-Cells, reverse leukemia

Tweet

Blocking the signals from a protein that activates cells in the immune system could help kill cells that cause a rare form of blood cancer, according to physicists and oncologists who combined computer modeling and molecular biology in their discovery.

Researchers say the breakthrough could provide more efficient ways of targeting diseases such as leukemia, and help in the potential development of vaccines for viruses that cause AIDS.

U of MN study shows link between gene variations and cancer survival

Tweet

Scientific research shows that certain genes can influence a person's likelihood to contract particular diseases, cancer for example. New research at the Masonic Cancer Center, University of Minnesota demonstrates that genetic markers may also show a person's likelihood to survive the disease.

Spanish scientists confirm the existence of electric activity in Titan

Tweet

Physicists of the University of Granada and the University of Valencia (Spain) have developed a proceeding to analyse specific data sent by the Huygens probe from Titan, the largest moon of Saturn, proving "in an unequivocal way" that there is natural electric activity in its atmosphere. The scientific community thinks that there is a higher probability that organic molecules precursors to life could form in those planets or satellites which have an atmosphere with electric storms.

Gene mutation in worms key to alcohol tolerance

Tweet

The work follows a study carried out by Oregon Health and Science University, which suggested a link between a gene mutation in mice and tolerance to alcohol. Researchers at Liverpool have investigated this in worms, looking specifically at the role the gene plays in communication between cells in the nervous system.
