Fermat's Last Theorem—the idea that a certain simple equation had no solutions— went unsolved for nearly 350 years until Oxford mathematician Andrew Wiles created a proof in 1995. Now, Case Western Reserve University's Colin McLarty has shown the theorem can be proved more simply.
The theorem is called Pierre de Fermat's last because, of his many conjectures, it was the last and longest to be unverified.
WASHINGTON, DC, March 4, 2013—Exercise can affect your sleep. The results of the National Sleep Foundation's 2013 Sleep in America® poll show a compelling association between exercise and better sleep.
"Exercise is great for sleep. For the millions of people who want better sleep, exercise may help," says David Cloud, CEO of the National Sleep Foundation (NSF).
Exercisers say they sleep better
Do cats purrr-ferrr sardines or sweets? The American Chemical Society (ACS), the world's largest scientific society, today released a new Bytesize Science video that explains why cats, unlike humans and other mammals, are indifferent to sweet flavors. Produced by the ACS Office of Public Affairs, it is available at www.BytesizeScience.com.
WASHINGTON and NEW YORK— A new report by the Geiger Gibson/RCHN Community Health Foundation Research Collaborative at the George Washington University School of Public Health and Health Services (SPHHS) examines the potential impact of sequestration on community health centers and their patients and communities.
Washington, DC—The National Commission on Physician Payment Reform issued a report today detailing a series of sweeping recommendations aimed at reining in health spending and improving quality of care by fundamentally changing the way doctors are paid. The Commission, chaired by former Robert Wood Johnson Foundation president Steven A.
A new long-term study of honey bee health has found that a little-understood disease study authors are calling "idiopathic brood disease syndrome" (IBDS), which kills off bee larvae, is the largest risk factor for predicting the death of a bee colony.
Suppose you could replace "Made in China" with "Made in my garage." Suppose also that every time you polished off a jug of two percent, you would be stocking up on raw material to make anything from a cell phone case and golf tees to a toy castle and a garlic press.
And, you could give yourself a gold medal for being a bona fide, recycling, polar-bear-saving rock star.
A new study has examined how bacteria clog medical devices, and the result isn't pretty. The microbes join to create slimy ribbons that tangle and trap other passing bacteria, creating a full blockage in a startlingly short period of time.
New research in the Journal of Clinical Investigation reveals that tumours in melanoma patients deliberately create conditions that knock out the body's 'premier' immune defence and instead attract a weaker immune response unable to kill off the tumour's cancerous cells.
The study also highlights a potential antibody biomarker that could help predict prognosis and identify which patients are most likely to respond to specific treatments.
Alexandria, VA – The American Geosciences Institute (AGI) and American Geophysical Union (AGU) have released a recording of the latest AGU/AGI Heads and Chairs webinar. This month's session focuses on legal issues related to field trips and field courses. The webinar, led by panelists David Mogk from Montana State University and Steven Whitmeyer from James Madison University, serves as a guide for reducing risk and liability for geoscience departments, and reviews tips for properly planning a safe and enjoyable field trip.
Research now reveals that fish can migrate to avoid the threat of being eaten. A new study from Lund University in Sweden shows that roach fish leave lakes and move into surrounding streams or wetlands, where they are safer from predators.
Every year, millions of animals migrate worldwide. In most cases, this is due to a shortage of food or other environmental factors. However, few research studies have focused on migration as a strategy to avoid predators. It is not easy to measure and quantify the risk of an animal being eaten.
Los Angeles, CA (February 28, 2013) — While those active on social media aren't shy about expressing opinions on their Facebook pages, how much do their "Likes" really reflect the quality of an organization? American Journal of Medical Quality (a SAGE journal) recently published a study that found that Facebook "Likes" were indeed an indicator of hospital quality and patient satisfaction.
"Findings suggest that Facebook offers an additional resource, beyond surveys, to gauge the attitudes of patient populations," wrote study authors Alex Timian et.al.
Quality is a central component of any discussion around health care and one of the key dimensions and measurements of quality care is the patient experience. However, many healthcare organizations struggle to become 'patient focused' and fail to score well on patient satisfaction surveys. New research from Brigham and Women's Hospital, published in the March edition of British Medical Journal Quality and Safety, offers a potential explanation -- insufficient support from hospital management to improve the patient experience by engaging physicians and nurses in the process.
Los Angeles, CA (March 01, 2013). In a 2012 report, the Obama administration announced that it was "jumpstarting" the nuclear industry. Because of the industry's long history of permitting problems, cost overruns, and construction delays, financial markets have been wary of backing new nuclear construction for decades. The supposed "nuclear renaissance" ballyhooed in the first decade of this century never materialized. And then came Fukushima, a disaster that pushed countries around the world to ask: Should nuclear power be part of the energy future?
The altruism and generosity of Mother Teresa is disputed in a paper by humanities scholars Serge Larivée and Genevieve Chenard of University of Montreal's Department of Psychoeducation and Carole Sénéchal of the University of Ottawa's Faculty of Education.
