A study by Hans-Peter Hartung, M.D., of Heinrich-Heine-Universität, Düsseldoft, Germany, and colleagues examines the association between IL-17F and treatment response to interferon beta-1b among patients with relapsing-remitting multiple sclerosis. (Online First)

Even if Australians with newly diagnosed bowel cancer were routinely tested for a genetic predisposition to further cancers, one in three people would still not take the necessary steps to use that information to prevent further disease.

Researchers from UNSW Medicine took the extra step of screening for the hereditary Lynch syndrome in the 2,100 people with colorectal cancer who presented at a number of NSW hospitals* over a three-year period.

U.S. workfare programs have been praised by some for cutting welfare rolls and improving the economic well-being of families. But little is known about how these policies affected participants' health and mortality. Researchers at Columbia University's Mailman School of Public Health studied enrollees in Florida's Family Transition Program who were given a time limit for welfare benefits and exposed to job training. They were compared to a control group who received traditional welfare benefits.

SALT LAKE CITY, June 3, 2013 – Most apes eat leaves and fruits from trees and shrubs. New studies spearheaded by the University of Utah show that human ancestors expanded their menu 3.5 million years ago, adding tropical grasses and sedges to an ape-like diet and setting the stage for our modern diet of grains, grasses, and meat and dairy from grazing animals.

To the list of oncogenic drivers of lung cancer that includes ALK, EGFR, ROS1 and RET, results of a University of Colorado Cancer Center study presented at ASCO 2013 show that mutations in the gene NTRK1 cause a subset of lung cancers.

GAINESVILLE, Fla. — The fate of a species may rest upon a single butterfly captured in late May by University of Florida lepidopterists.

A UF research technician netted a female Schaus swallowtail in Biscayne National Park on Elliott Key, the first capture of a female since a multi-agency work group got a permit to do so last year.

The Schaus population has declined so much that last year the U.S. Fish and Wildlife Service (Service) issued UF an emergency permit to collect eggs.

Researchers at the University of California, San Diego School of Medicine, with colleagues at the University of Rochester Medical Center, have identified a new mechanism that appears to suppress tumor growth, opening the possibility of developing a new class of anti-cancer drugs.

Researchers at Karolinska Institutet in Sweden have found a promising strategy for defeating neuroblastoma – a malignant form of cancer in children – that focuses on the so-called MYCN protein. A specific chemical molecule helps to break down MYCN, which either kills the cancer cell or makes it mature into a harmless neuron. The discovery, which is published in the scientific journal PNAS, raises hopes for new and more effective treatments in the future.

SAN FRANCISCO (June 3, 2013) — The old saying "You are what you eat" takes on new significance in the most comprehensive analysis to date of early human teeth from Africa. Prior to about 3.5 million years ago, early humans dined almost exclusively on leaves and fruits from trees, shrubs, and herbs—similar to modern-day gorillas and chimpanzees. However, about 3.5 million years ago, early human species like Australopithecus afarensis and Kenyanthropus platyops began to also nosh on grasses, sedges, and succulents—or on animals that ate those plants.

Diseases such as tuberculosis, anthrax, and shigellosis -- a severe food-borne illness -- eventually could be treated with an entirely new and more-effective kind of antibiotic, thanks to a team of scientists led by Kenneth Keiler, an associate professor of biochemistry and molecular biology at Penn State University.

A new look at the diets of ancient African hominids shows a "game changer" occurred about 3.5 million years ago when some members added grasses or sedges to their menus, according to a new study led by the University of Colorado Boulder.

SINGAPORE – A research team led by the Duke-NUS Graduate Medical School (Duke-NUS) in Singapore has identified ways to inhibit the function of a key protein linked to stem cell-like behavior in terminal-stage chronic myeloid leukemia (CML), making it possible to develop drugs that may extend the survival of these patients.

The flora and fauna of the American west coast is generally believed to be well explored and studied. However, a new study and a taxonomic assessment of the octocorals from the north eastern Pacific Ocean proves such assumptions wrong, with two new beautiful and colourful species of soft corals alongside a new genus. The study was published in the open access journal Zookeys.

A new study of 365 sell-side financial analysts shows that private phone calls with managers remain an essential source of analysts' earnings forecasts and stock recommendations – even in light of regulations limiting businesses' selective disclosure of financial information.

Toronto, June 3, 2013 – A mismatch between the departure schedules of songbirds and higher spring temperatures at their breeding sites is putting them at risk, according to a new study out of York University.
