Cold Spring Harbor, N.Y. – A math-based game that has taken the world by storm with its ability to delight and puzzle may now be poised to revolutionize the fast-changing world of genome sequencing and the field of medical genetics, suggests a new report by a team of scientists at Cold Spring Harbor Laboratory (CSHL). The report will be published as the cover story in the July 1st issue of the journal Genome Research.

Girls typically are less physically active than boys, but a Kansas State University researcher has found that organizations like Girl Scouts provide an ideal setting to get girls moving early in life and to develop lifelong healthy habits.
Richard Rosenkranz, assistant professor in human nutrition at K-State, did a study using interventions with Girl Scout troops. He trained group leaders to instruct exercise sessions and promote healthful eating, and in effect taught the girls about a healthy lifestyle and increased their participation in exercise activities.
Tobacco acts as a precipitating factor for headaches, specifically migraines. This is indicated in a study which shows that smokers have more migraine attacks and that smoking more than five cigarettes a day triggers this headache. The work has appeared in the Journal of Headache and Pain.
While cancer touches the lives of many humans, it is also a major threat to wild animal populations as well, according to a recent study by the Wildlife Conservation Society (WCS).
A newly published paper in the July edition of Nature Reviews Cancer compiles information on cancer in wildlife and suggests that cancer poses a conservation threat to certain species. The WCS authors highlight the critical need to protect both animals and people through increased health monitoring.
There is minimal data evaluating the prevalence of GERD complications in any United States general population, other than non-Hispanic whites. Presently, it is thought that such complications occur less frequently in African-Americans than in non-Hispanic whites. A research group in Jacksonville, FL investigated the prevalence of reflux esophagitis between non-Hispanic whites and African-Americans. The distribution of esophagitis severity and its complications were equivalent between groups, except for Barrett's esophagus.
To stretch a supply of salt generally means using it sparingly.
But researchers from Sandia National Laboratories and the University of Pittsburgh were startled when they found they had made the solid actually physically stretch.
"It's not supposed to do that," said Sandia principal investigator Jack Houston. "Unlike, say, gold, which is ductile and deforms under pressure, salt is brittle. Hit it with a hammer, it shatters like glass."
Global warming will likely mean more unpredictable weather, scientists say, and a new study by researchers at the University of Georgia pins down, possibly for the first time, how drought conditions in an area's fall and winter may effect tornado activity the following spring.
The study, published today in the journal Environmental Research Letters, is specific to Georgia and the Southeast, but further study could reveal patterns that might make this more general—including the already tornado-prone Great Plains.
June 24/Geneva — Climate has always presented a challenge to farmers, herders, fishermen and others whose livelihoods are closely linked to their environment, particularly those in poor areas of the world. A type of insurance, called index insurance, now offers significant opportunities as a climate-risk management tool in developing countries, according to a new publication launched today during a workshop at the Global Humanitarian Forum (GHF) in Geneva.
Current research suggests that levels of gastrin play a key role in the development of Helicobacter-induced stomach cancer. The related report by Takaishi et al, "Gastrin is an essential cofactor for Helicobacter-associated gastric corpus carcinogenesis in C57BL/6 mice," appears in the July 2009 issue of The American Journal of Pathology.
New York, NY … Almost 60 mantle cell lymphoma (MCL) specialists from around the world gathered in Atlanta, GA for the Lymphoma Research Foundation's (LRF) Sixth Annual Mantle Cell Lymphoma Consortium (MCLC) Scientific Workshop. Attendees heard presentations addressing several key issues including the biology of MCL, prognostic indicators, new molecular targets, chemoimmunotherapy, transplantation and novel therapeutic approaches.
Madeira, Portugal: Small whales are disappearing from the world's oceans and waterways as they fall victim to fishing gear, pollution, and habitat loss – compounded by a lack of conservation measures such as those developed for great whales, according to a new WWF report.
Small cetaceans: The Forgotten Whales, released today, states that inadequate conservation measures are pushing small cetaceans – such as dolphins, porpoises and small whales – toward extinction as their survival is overshadowed by efforts to save their larger cousins.
Antibiotic prescribing for respiratory illnesses should be standardised across Europe to help reduce inappropriate prescribing and resistance, say experts in a study published on bmj.com today.
Antibiotic resistance is a growing problem worldwide. In Europe, 39% of invasive bacteria were resistant to penicillin in 2006 and unnecessary antibiotic prescribing, particularly for respiratory illnesses, has been blamed for increasing antibiotic resistance.
GALVESTON, Texas — Researchers at the University of Texas Medical Branch at Galveston have discovered two biochemical pathways that the Ebola virus relies on to infect cells. Using substances that block the activation of those pathways, they've prevented Ebola infection in cell culture experiments — potentially providing a critical early step in developing the first successful therapy for the deadly virus.
