True or false? Women are more emotional than men. Boys are better than girls at math and science. "Many things that 'everyone knows' about human sex differences are not scientifically accurate," says professor Caitilyn Allen, a plant pathologist at University of Wisconsin-Madison. Yet, she adds, these ideas "affect individual life decisions and broader social policies. Getting the facts right leads to increased opportunities for everyone and improves the quality of science in general." Separating fact from fiction in experimental research is one of the goals behind a new postdoctoral program in feminist biology in the UW's department of gender and women's studies. It will also train early-career scientists to avoid such biases in their own research. The program is the first of its kind in the country. It is funded through a bequest from scientist and feminist science advocate Dr. Gertraude Wittig, who experienced gender biases firsthand when she earned a Ph.D. in biology in the 1950s. Professor Janet Hyde, director of the UW's Center for Research on Gender and Women, will oversee the program and serve as a mentor to each postdoctoral fellow. Hyde says that patriarchal attitudes in biology have not only excluded women from the field, but … Continue reading →

TMC is the only Kentucky college to offer a marine biology degree program. Classes for the new marine biology program will be taught at Newport Aquarium and the Biology Field Station on the Ohio River. Students will conduct research onsite. "We are very excited to continue our support for science education in the Greater Cincinnati-Northern Kentucky community," said Eric Rose, Vice President and Executive Director of Newport Aquarium. "This new agreement deepens and expands Newport Aquarium's long established relationship with Thomas More College."

PUBLIC RELEASE DATE: 1-May-2014 Contact: Cody Mooneyhan cmooneyhan@faseb.org 301-634-7104 Federation of American Societies for Experimental Biology In a new report published in the Journal of Leukocyte Biology, scientists lay the groundwork for the development of novel tumor therapies that may help rid the body of cancer by inhibiting the recruitment of a specific suppressive immune cell type called "regulatory T-cells." The approach described in the report shows that an immune molecule, called interleukin-27, promotes the recruitment of regulatory T-cells. This suggests that by stopping IL-27's immunosuppressive function, cancer therapies can more effectively activate other T-cells to attack and destroy cancer tumors. "Our study not only provides a new insight into the effects of interleukin-27 in regulatory T-cell biology, but also greatly improves our understanding of the physiological functions of interleukin-27, especially in tumor immunology," said Siyuan Xia, a researcher involved in the work from the State Key Laboratory of Medicinal Chemical Biology, College of Life Sciences, Nankai University, Tianjin, China. "We hope our study could shed new light on developing novel interventional therapies by targeting regulatory T-cells in cancer patients." Scientists made this discovery by using mice deficient in a specific subunit of interleukin-27 called p28. They compared the tumor … Continue reading →

Ade Ilesanmi/Old Gold & Black Elise Madar was born in Baltimore, M.D., but has spent most of her life growing up in northeast Ohio, right outside of Cleveland. Coming from a family of engineers, Madar had a strong background in mathematics and the sciences, eventually fostering an interest in biology. Her college search was focused on schools with strong neuroscience programs and in areas with temperate climates, which made Wake an easy choice. I really wanted to get out of the cold weather, Madar said. She thoroughly enjoys her major, as it has afforded her the opportunity to build strong relationships with many of the professors in the biology department. I really like it because of the faculty. Ive gotten to know them very well, Madar said. It all started during her sophomore year, when she began doing research with Wayne Silver, a professor in the biology department. Shes one of the best Wake Forest students Ive had in class and lab in all the years Ive been here, Silver said. She is always extremely well organized, incredibly hard working, perfectly down-to-earth and always seems to be happy. She is an incredible student and has a 4.0 GPA. Madar also … Continue reading →

Day 3 of the Experimental Biology meeting was arguably one of the most exciting for comparative physiology. Here are the highlights from Monday: Morning Seminars: Birgitte McDonald from Aarhus University, Denmark presented, Deep-diving sea lions exhibit extreme bradycardia in long-duration dives. Birgitte and Dr. Paul Ponganis measured the heart rate of California sea lions (Z. californianus) using digital electrocardiogram loggers and found that the heart rate was reduced (bradycardia) during dives along with reduced blood flow to the lungs and periphery. This helps preserve the oxygen content in the lungs and encourage muscles to use stored oxygen while conserving oxygen in the blood. Birgitte was also awarded an APS International Early Career Physiologist Travel Award to attend the meeting. Matthew Pamenter (U. British Columbia) presented work that he conducted with Yvonne Dzal and William Milsom entitled, Profound metabolic depression in the hypoxia-tolerant naked mole rat. What I found most interesting about this talk is that naked mole rats are the most hypoxia (low oxygen) tolerant mammal known. These animals are able to maintain normal activity levels even in oxygen conditions as low as 3% (normal oxygen concentrations of the air we breathe at sea level are ~21%). This amazing adaptability … Continue reading →
