While most of the evidence linking HGSOC to the fallopian tubes has so far been only circumstantial, a new Dana-Farber Cancer Institute study suggests there is a direct connection, a finding that could aid in the development of better treatments for the cancer.

Medical researchers today held out promise that a simple injection is being developed to limit the devastating consequences of heart attacks and strokes.

Described by the lead researcher as 'a fascinating new achievement', work has already begun to translate the research into novel clinical therapies.

The University of Leicester led an international team whose research has been published today in the Early Online Edition of the Proceedings of the National Academy of Sciences (PNAS).

OTTAWA, ONTARIO, CANADA — Canada needs to modernize its pharmaceutical drug laws to ensure that new drugs as well as older drugs are safe for Canadians, states an editorial in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/cgi/doi/10.1503/cmaj.110489.

A new study of older diabetes patients has found that well-controlled blood sugar levels were associated with a lower risk of major complications such as heart attacks, amputation and kidney disease, but the very lowest blood sugar levels were associated with a small but significant increased risk of death. The study published in the June 2011 issue of the journal Diabetes Care, followed more than 70,000 type 2 diabetes patients from Kaiser Permanente who were over 60 years of age for four years.

Animals and plants may need extra habitats to survive the challenge of climate change, according to research by scientists at the University of York.

Human activities have reduced natural habitats to isolated "islands", making it more difficult for some species to re-locate to cooler regions in response to their existing locations growing warmer.

PROVIDENCE, R.I. [Brown University] — Adolescents who believe they matter to their families are less likely to threaten or engage in violence against family members, according to a new study led by Brown University sociologist Gregory Elliott.
