"A new study on cellphone safety has found that carrying a phone in a shirt or pants pocket exceeds radiation exposure guidelines spelled out by the the Federal Communications Commission (FCC), and that children absorb twice as much cellphone radiation as adults. The study published in the journal Electromagnetic Biology and Medicine criticizes the way phone manufacturers measure levels of microwave radiation, and calls for the industry standard to be scrapped."

"A dizzying array of research suggests alcohol can have both good and bad effects, but making sense of such studies all comes down to who you are and how much you drink. That point was driven across Tuesday with the release of a U.S. study suggesting women who consume three to six alcoholic beverages a week face a small increased risk of breast cancer, but it's not enough of a danger to stop drinking. The study in the Journal of the American Medical Association involved 105,986 nurses who were tracked for three decades."

"Adults who ate canned soup daily showed a jump in levels of the plasticizer BPA in their urine, according to a small study. The study of 75 people in Tuesday's issue of the Journal of the American Medical Association is one of the first to quantify BPA levels in humans after eating canned foods compared with eating freshly prepared ingredients. Bisphenol A is an industrial chemical used to make polycarbonate plastic for water bottles and food containers as well as the protective lining in metal cans."

The criminal brain has always held a fascination for James Fallon. For nearly 20 years, the neuroscientist at the University of California-Irvine has studied the brains of psychopaths. He studies the biological basis for behavior, and one of his specialties is to try to figure out how a killer's brain differs from yours and mine.

"Obesity has a greater impact on the blood pressure of teenage girls than on teenage boys, a US study has suggested. High blood pressure is a risk factor for heart disease and stroke in later life. The study of 1,700 teenagers, presented to the American Physiological Society conference, found girls had three times the risk of higher blood pressure."

"Nearly 20% of women in the US are raped or suffer attempted rape at some point in their lives, a US study says. Even more women, estimated at 25%, have been attacked by a partner or husband, the Centers for Disease Control said."

"Certain trees are able to clone themselves, which raises the tantalising possibility that they could effectively "live forever". But a study published in the journal PLoS Biology has dashed that hope. "

"The upper layer of the world's ocean has warmed since 1993, indicating a strong climate change signal, according to a new study. The energy stored is enough to power nearly 500 100-watt light bulbs per each of the roughly 6.7 billion people on the planet."

The latest study led by the Institute of Cancer Epidemiology in Denmark looked at more than 350,000 people with mobile phones over an 18-year period.

"The latest study, carried out at the Haukeland University Hospital in Bergen, built on the previous discovery by testing 30 patients with CFS. Half were given two doses of Rituximab, a cancer drug which eliminates a type of white blood cell, while the other half were given a fake treatment. In those patients receiving the drug, 67% reported an improvement in a score of their fatigue levels. Just 13% showed any improvement in the sham group. "

"A team at the Carnegie Institution for Science subjected the material to pressures up to 1.4 million times atmospheric pressure at sea level, and temperatures up to 2,200C. They found that it pulls off the trick of changing its electrical properties without any shifting of shape - it can be an insulator or conductor depending just on temperature and pressure. Combined with computer simulations of just what was going on with the material's electrons, the group claim that the results show a new type of metallisation. "At high temperatures, the atoms in iron oxide crystals are arranged with the same structure as common table salt," said Ronald Cohen, a co-author of the study. "Just like table salt, iron oxide at ambient conditions is a good insulator-it does not conduct electricity.""

"Dr. Levine, a Howard Hughes Medical Institute (HHMI) investigator at the medical center, decided to focus on one specific health effect of exercise -- the ability of exercise to prevent blood sugar abnormalities in the face of a high-fat diet. Her mouse study provides the first evidence that exercise stimulates autophagy."

"In the few, limited tests conducted outside the United States, BPS shows estrogenic activity - not as strong as BPA, but not a good sign. BPS is now used in the United States to make PES (polyethersulfone) plastic. Some baby bottles marketed as BPA-free use PES plastic. Bisphenols are shaping up to be a dysfunctional family of chemicals. BPAF is BPA's fluorinated twin. It is used in electronic devices, optical fibers and more. New studies have found BPAF to be an even more potent endocrine disrupter than BPA. Bisphenol B and Bisphenol F are other variants used instead of BPA in various products. In the limited testing done on those chemicals in other countries, scientists found Bisphenol B to be more potent than BPA in stimulating breast cancer cells. "

"In an enormous display of survival of the fittest, the forests of the future are taking a new shape. In a new report, scientists outline the impact that a changing climate will have on which tree species can survive, and where. The study suggests that many species that were once able to survive and thrive are losing their competitive footholds, and opportunistic newcomers will eventually push them out."

"Think the school you chose for your child is good? Better than that academic straggler just down the road? Think again. A new study is raising questions about the information parents commonly use to chose a school for their children, especially in provinces like Alberta and British Columbia, where families commonly shop around for an education."

Join Bill Nye as he delves into the Greatest Discoveries in Biology. This program explains how the early use of microscopes and Anton Van Leeuwenhock's accidental discovery set the stage for studying microorganisms. It explores 19th century research breakthroughs and covers cell division, sex cell division, and cell differentiation. Learn how the discovery of mitochondria has helped us understand reproduction, ancestral lines, and cancer; how cells convert sugars, fats, and proteins into energy in the Krebs Cycle; and how they communicate through neurotransmitters and hormones. Explore the process of photosynthesis and how the discovery of the ecosystem process bridged biology with physics, chemistry, and other fields of science that describe the environment.

According to a paper in PLoS Computational Biology, "PageRank" can be applied to the study of food webs.

"The two developed a technique that uses bacteria to break down the foam plastic used in many disposable cups, fast-food containers and packing materials."
