Four years ago, Angela Stimpson agreed to donate a kidney to a complete stranger. "The only thing I knew about my recipient was that she was a female and she lived in Bakersfield, Calif.," Stimpson says. It was a true act of altruism Stimpson risked pain and suffering to help another. So why did she do it? It involved major surgery, her donation was anonymous, and she wasn't paid. "At that time in my life, I was 42 years old. I was single, I had no children," Stimpson says. "I loved my life, but I would often question what my purpose is." Angela Stimpson smiles before surgery to donate a kidney on Sept. 22, 2010, at Weill-Cornell Hospital in New York.

When she read about the desperate need for kidneys, Stimpson, a graphic artist who lives in Albany, N.Y., says she found her purpose. She now blogs about her experience and encourages others to become donors. People like Stimpson are "extraordinary altruists," according to Abigail Marsh. She's an associate professor of psychology at Georgetown University … Continue reading →

PUBLIC RELEASE DATE: 22-Sep-2014 Contact: Alanna Orpen alanna.orpen@biomedcentral.com BioMed Central @biomedcentral Butterflies eating food collected from cities around the Fukushima nuclear meltdown site showed higher rates of death and disease, according to a study published in the open access journal BMC Evolutionary Biology. Researchers fed groups of pale blue grass butterflies (Zizeeria maha) leaves from six different areas at varying distance from the disaster site, and then investigated the effects on the next generation. Feeding offspring the same contaminated leaves as their parents magnified the effects of the radiation. But offspring fed uncontaminated leaves were mostly like normal butterflies, and the authors say this shows that decontaminating the food source can save the next generation. The 2011 meltdown at the Fukushima Dai-ichi nuclear power plant released substantial amounts of radiation into the surrounding area. Humans were evacuated, and no significant health effects have been reported, but the scientists from the University of the Rukyus, Okinawa, Japan, are studying the impact on the area's wildlife. In a previous study, the group suggested that eating leaves with high levels of radiation seriously affected the pale grass blue butterfly. Their new study investigated the effect of eating leaves with much lower levels of … Continue reading →
