MIT researchers have confirmed the first sighting of a Dungeness crab in the Atlantic Ocean. The male, whose species is common on North America’s West Coast, was caught off Thatcher Island, Massachusetts, on July 19 by Lou Williams, captain of the fishing vessel Orin C. The origin of the crab is not known.

Researchers set out to investigate the association between treatment with TNF blockers and occurrence of cancer in a large sample of patients with RA. Their results indicate that biologic DMARD therapy poses no greater risk for cancer than therapy with a standard prescription DMARD, methotrexate (MTX).

Although human genes contribute significantly to a person’s health and behavior, these two kinds of traits aren’t closely linked at all. In fact, a study appearing this month in the Public Library of Science found absolutely no connection between the hard-driving personality and heart disease, contrary to previous studies and conventional wisdom.

A newly discovered enzyme inhibitor, identified by researchers originally looking for biological pest controls, may lead to pain relief for sufferers of arthritis and other inflammatory diseases, say researchers at the University of California, Davis. The finding, hailed by a noted inflammatory disease expert “as the most important discovery in inflammation in more than a decade,” may also reduce side effects associated with the painkiller, Vioxx.
