A report issued today, co-authored by the Wildlife Conservation Society (WCS) working in conjunction with the Turtle Conservation Coalition, lists the 25 most endangered turtle species from around the world – some of which currently number less than five individuals.

AMES, Iowa - In the past 20 years, Martin Luther King's dream of the day when "little black boys and black girls will be able to join hands with little white boys and white girls" through school desegregation has not been realized for most, according to research by an Iowa State University economist.
David Frankel, associate professor of economics, looked at public school enrollments from every school district in the country and found that school segregation between blacks and whites has improved only slightly from 1987 to 2007.
It can be a helpless and heartbreaking situation for families as they try to confront a family member with an eating disorder. What they may not know is that there's a society on the Internet that is dedicated to thwarting any recovery from this dangerous and possibly fatal behavior.
BLOOMINGTON, Ind. -- Polygamy practiced by some 19th century Mormon men had the curious effect of suppressing the overall offspring numbers of Mormon women in plural marriages, say scientists from Indiana University Bloomington and three other institutions in the March 2011 issue of Evolution and Human Behavior.
Simply put, the more sister-wives a Mormon woman had, the fewer children she was likely to produce.
Monday, February 21, 2011 – Cleveland – A biological pathway that transforms normal cells into aggressive tumors has been discovered by researchers at Cleveland Clinic's Lerner Research Institute.
This research, led by Philip Howe, Ph.D., of the Cancer Biology Department of the Lerner Research Institute of Cleveland Clinic, was recently published in a recent issue of Molecular Cell.
Many of the substances in our most common medicines are manufactured in India. Some of these factories release huge quantities of drugs to the environment. Swedish scientists now show that bacteria in polluted rivers become resistant to a range of antibiotics. International experts fear that this may contribute to the development of untreatable infectious diseases world-wide.
An international scientific team has shown that strong links between the corals reefs of the south China sea, West Pacific and Coral Triangle hold the key to preserving fish and marine resources in the Asia-Pacific region.
HOUSTON -- (Feb. 21, 2011) -- Texas winters may seem mild to those who move here from farther north, but they can be hard to adjust to for immigrants from warmer climates. This is true not only for people but for ants too. A new study by biologists at Rice University and the University of Texas at Austin (UT) finds that the Texas leaf-cutter ant Atta texana, whose ancestors emigrated from the tropics, adapted to the relatively harsh Texas winters in an unusual way -- through their food.
Like all leaf-cutter ants, A. texana cuts leaves but does not eat them.
COLUMBIA, Mo. – Most people would never suspect that a "trash tree," one with little economic value and often removed by farmers due to its ability to destroy farmland, could be the key to fighting a deadly bacterium. Now, a University of Missouri researcher has found an antibiotic in the Eastern Red Cedar tree that is effective against methicillin-resistant Staphylococcus aureus (MRSA), a "superbug" that is resistant to most medications.
A strategy developed by Massachusetts General Hospital (MGH) researchers to shield the ovaries of female mammals from the damaging effects of radiation and chemotherapy has passed an important milestone. A collaborative study with investigators from Oregon Health and Sciences University (OHSU), published online in the journal Fertility and Sterility, reports that brief preexposure of the ovaries to an FDA-approved agent called FTY720 preserved the fertility of female rhesus monkeys exposed to potentially lethal doses of radiation.
Chemotherapeutic agents, used in cancer treatment, destroy not only cancer cells but also healthy cells, thus affecting germ cells as well. Consequently, after surviving cancer many female patients are confronted with the diagnosis: infertility. For a long time a relationship between infertility and chemotherapeutic agents has been assumed, but until now, the exact mechanism was not known.
The bacterium, called Pseudomonas aeruginosa, is the most common cause of persistent and fatal lung infections in cystic fibrosis patients. Scientists at Liverpool identified a particularly virulent strain of the bacteria that is transmissible between patients. The Liverpool Epidemic Strain (LES), referred to as a cystic fibrosis 'superbug', can cause aggressive infection and results in progressive lung decline.
February 22, 2011 — (BRONX, NY) — Researchers at Albert Einstein College of Medicine of Yeshiva University have developed an experimental vaccine that appears to protect against an increasingly common and particularly deadly form of pneumococcal pneumonia. Details of the new vaccine, which was tested in an animal model, are reported in a paper published today in the Journal of Infectious Diseases.
ST. PAUL, Minn. – Middle-age men and women who have cardiovascular issues, such as high cholesterol and high blood pressure, may not only be at risk for heart disease, but for an increased risk of developing early cognitive and memory problems as well. That's according to a study released today that will be presented at the American Academy of Neurology's 63rd Annual Meeting in Honolulu April 9 to April 16, 2011.
