Exercise could fortify immune system against future cancers

Exercise could fortify immune system against future cancers

ScienceDaily (Oct. 10, 2012) — Researchers may soon be able to add yet another item to the list of exercise’s well-documented health benefits: A preliminary study suggests that when cancer survivors exercise for several weeks after they finish chemotherapy, their immune systems remodel themselves to become more effective, potentially fending off future incidents of cancer. The finding may help explain why exercise can significantly reduce the chances of secondary cancers in survivors or reduce the chances of cancer altogether in people who have never had the disease.

Nerve and muscle activity vary across menstrual cycle

Nerve and muscle activity vary across menstrual cycle

ScienceDaily (Oct. 10, 2012) — Numerous studies have shown that female athletes are more likely to get knee injuries, especially anterior cruciate ligament (ACL) tears and chronic pain, than their male counterparts. While previous research has focused on biomechanical differences as the main source of these problems, a new study suggests another distinction that could play a role: changes across the menstrual cycle in nerves that control muscle activity Continue reading

Anthropologist finds evidence of hominin meat eating 1.5 million years ago: Eating meat may have ‘made us human’

Anthropologist finds evidence of hominin meat eating 1.5 million years ago: Eating meat may have ‘made us human’

ScienceDaily (Oct. 3, 2012) — A skull fragment unearthed by anthropologists in Tanzania shows that our ancient ancestors were eating meat at least 1.5 million years ago, shedding new light into the evolution of human physiology and brain development. “Meat eating has always been considered one of the things that made us human, with the protein contributing to the growth of our brains,” said Charles Musiba, Ph.D., associate professor of anthropology at the University of Colorado Denver, who helped make the discovery.

Taking mathematics to heart

ScienceDaily (Sep. 28, 2012) — Mathematics might seem like an abstract discipline, remote from real-world applications but their equations can significantly help understand and simulate the functioning of nature. Professor Alfio Quarteroni of the École Polytechnique Fédérale de Lausanne (EPFL, Switzerland) is leading the Mathcard project in developing mathematical models of the blood flow in our cardiovascular system.

Into the mind of the common fruit fly

ScienceDaily (Sep. 25, 2012) — Although they’re a common nuisance in the home, fruit flies have made great contributions to research in genetics and developmental biology. Now a Tel Aviv University researcher is again turning to this everyday pest to answer crucial questions about how neurons function at a cellular level — which may uncover the secrets of neurological disorders such as Alzheimer’s disease Continue reading
