Trying to stay ahead of a deadly disease that has wiped out more than 100 species, scientists at the Smithsonian Tropical Research Institute continue to discover new frog species in Panama: Pristimantis educatoris, from Omar Torrijos National Park, and P. adnus from Darien Province near the Colombian border.
Infants born with a severely underdeveloped heart who undergo a newer surgical procedure are more likely to survive their first year and not require a heart transplant than those who have a more traditional surgical procedure, according to a report by researchers supported by the National Heart, Lung, and Blood Institute (NHLBI), which is part of the National Institutes of Health. The study of 549 newborns, however, suggests that after the first year, the two surgical procedures for the relatively rare condition yield similar results.
Although congenital heart disease represents the most common major birth defect, scientists have not previously identified the common variation in the genes that give rise to it. Now genetics and cardiology researchers, two of them brothers, have discovered a genetic variant on chromosome 5 that strongly raises the risk of congenital heart disease.
Damselfish are killing head corals and adding stress to Caribbean coral reefs, which are already in desperately poor condition from global climate change, coral diseases, hurricanes, pollution, and overfishing. Restoring threatened staghorn coral, the damsels' favorite homestead, will take the pressure off the other corals, according to a new study published in the online journal PLoS ONE.
A New York State Museum scientist is one of several researchers who have become the first to use tiny radio transmitters to track bees over long distances in a forest habitat, yielding new insight into the role of bees in tropical forest ecosystems. The bee study research conducted by Dr. Roland Kays, the Museum's curator of mammals, and the other scientists, was published in the online peer reviewed journal PLoS ONE on May 26th.

With the help of ancient fossils unearthed in the Sahara desert, scientists have identified a new type of pterosaur (giant flying reptile or pterodactyl) that existed about 95 million years ago. According to the findings published in the online peer-reviewed scientific journal PLoS ONE on May 26th, the scientists consider the newly identified pterosaur to be the earliest example of its kind.
JACKSONVILLE, Fla. — Physicians now have two safe and effective options to treat their patients at risk for stroke, says a researcher at Mayo Clinic who led a large, NIH-funded, national clinical trial testing surgery or use of a stent to open a blocked carotid artery.
ANN ARBOR, Mich. — A trial on shunts used to direct blood flow to the lungs, led by researchers at the University of Michigan's C.S. Mott Children's Hospital, will lead to better outcomes for kids worldwide born with hypoplastic left heart syndrome, the most common severe heart birth defect.
Under the leadership of the University of Michigan, the first multi-institutional randomized prospective trial ever conducted in congenital heart surgery was just completed by the Pediatric Heart Network with funding from the National Heart, Lung, Blood Institute.
Governments and other organizations must intensify efforts to improve the health of women and children, particularly in the developing world where the lion's share of deaths occur, says Dr. Philip Baker, an internationally renowned medical researcher in obstetrics & gynecology. Baker is the lead author on a G8 positioning paper that included consultations with 20 of the world's leading medical experts on women and children's health.
Pediatric researchers report that a recently introduced surgical procedure offers infants with severely underdeveloped hearts a better chance at surviving during their first year of life, in comparison to the standard surgery.
Heart surgeons from 15 centers in the federally sponsored Pediatric Heart Network studied the outcomes in 549 newborns who received a complex series of surgeries for hypoplastic left heart syndrome (HLHS).
PHILADELPHIA –- Genetic researchers from the University of Pennsylvania have combined data from existing archaeological and linguistic studies of Africa with human genetic data to shed light on the demographic history of the continent from which all human activity emerged.
You might call it comparing apples and oranges, but lining up different species' genomes is common practice in evolutionary research. Scientists can see how species have evolved, pinpoint which sections of DNA are similar between species, meaning they probably are crucial to the animals' survival, or sketch out evolutionary trees in places where the fossil record is spotty.
But the tools used to align genomes from different species have serious quality-control issues, according to a study published online this week in the journal Nature Biotechnology.
In a major cancer-research breakthrough, researchers at the McGill University, Department of Biochemistry have discovered that a small segment of a protein that interacts with RNA can control the normal expression of genes – including those that are active in cancer.
