Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
Bumble bees have discriminating palettes when it comes to their pollen meals, according to researchers at Penn State. The researchers found that bumble bees can detect the nutritional quality of pollen, and that this ability helps them selectively forage among plant species to optimize their diets.
"Populations of many bee species are in decline across the world, and poor nutrition is thought to be a major factor causing these declines," said Christina Grozinger, director of the Center for Pollinator Research, Penn State. "Our studies can help identify plant species and stocks that provide high-quality nutrition for bumble bees and potentially other bee species, which will help in the development of pollinator-friendly gardens and planting strips."
The era of quantum computers is one step closer as a result of research published in the current issue of the journal Science. The research team has devised and demonstrated a new way to pack a lot more quantum computing power into a much smaller space and with much greater control than ever before. The research advance, using a 3-dimensional array of atoms in quantum states called quantum bits -- or qubits -- was made by David S. Weiss, professor of physics at Penn State University, and three students on his lab team.
An international research collaboration led by UCL scientists has developed ways to improve the quality and accuracy of information harvested from epigenome sequencing datasets in two new research papers published jointly in Nature Biotechnology and Nature Communications today. According to the studies, epigenome sequencing technologies can allow for more comprehensive analysis of cancers - a key component in the development of targeted approaches to combat cancer.
In a partnership melding neuroscience and electrical engineering, researchers from UNC-Chapel Hill and NC State University have developed a new technology that will allow neuroscientists to capture images of the brain almost 10 times larger than previously possible - helping them better understand the behavior of neurons in the brain.
Nervous systems are complex. After all, everything that any animal thinks or does is controlled by its nervous system. To better understand how complex nervous systems work, researchers have used an expanding array of ever more sophisticated tools that allow them to actually see what's going on. In some cases, neuroscience researchers have had to create entirely new tools to advance their work.
ITHACA, N.Y. - Games are usually more fun when you play with other people, but if you're playing an educational game, interacting with other players may help you learn more, according to Cornell University research.
Using a language-learning game called "Crystallize," created by Erik Andersen, assistant professor of computer science, and his students, researchers found that when players are required to work together they learn more words -- and enjoy the game more.
Andersen and colleagues described the game and reported on their user studies at the 2016 ACM Conference on Human-Computer Interaction in San Jose, California.
BLOOMINGTON, Ind. -- Using virtual tissue technology, researchers at Indiana University have identified a potential new drug target in the fight against polycystic kidney disease, an illness with no effective FDA-approved treatment that affects 200,000 people per year in the United States.
The study appears in the journal Molecular Biology of the Cell. It reveals that errors in how cells stick together give rise to two forms of kidney cysts.
These cysts can cause an adult kidney -- normally about the size of a fist and weighing less than a pound -- to grow to the size of a football that weights 20 to 30 pounds. Currently, only dialysis or a kidney transplant can delay death from the disease.
ANN ARBOR --If the United States responds to Zika the way it did to Ebola -- and early indications are that in many ways it is -- the country can expect missteps brought about by a lack of health care coordination and a lot of political finger pointing, according to an analysis by the University of Michigan.
Scott Greer of the U-M School of Public Health and colleagues studied the U.S. response to Ebola and found a fragmented system with no clear leadership, and considerable "strategic politicization" due to the outbreak's arrival during a midterm election year.
A program to improve orthopedic surgery residents' communication skills with older adults is having a positive impact, according to a new study. The program at Hospital for Special Surgery (HSS) seeks to enhance third-year residents' interactions with older adults by sensitizing the residents to their needs and dispelling negative misconceptions.
A study discussing the results of the Hospital for Special Surgery program was presented at the Council of Orthopaedic Residency Directors meeting on June 24, 2016 in Seattle.
Good communication skills are an important attribute for all physicians, yet patient surveys nationwide have shown that these skills are often lacking. It can be an even greater challenge for doctors when the patient is an older adult.
(Washington, DC) - Humans have a natural drive to reduce physical effort in nearly every activity, including using language. Instead of saying "goodbye", we often say "bye", getting the same message across with half the syllables. The ways that effort-reduction affect human language have been the subject of extensive research in the field of linguistics, though the overwhelming focus has been on spoken languages. By studying this effect in sign languages, two linguists from Swarthmore College have discovered a new way in which language is shaped by our innate drive to make physical activity easier.
Continuing their research into potential ingredients for human-safe pesticides, Drexel University researchers recently found an artificial sweetener that, while harmless for male fruit flies, proved particularly lethal for females.
Past research conducted by Drexel College of Arts and Sciences' Sean O'Donnell, PhD, professor and associate department head of Biodiversity, Earth & Environmental Science (BEES) and Daniel Marenda, PhD, an associate professor of Biology, indicated that erythritol, an artificial sweetener in name-brand products like Truvia, is poisonous to fruit flies.
GAINESVILLE, FL - Producers of container-grown landscape plants often use fertilizers to ensure that consumers take home healthy, vigorous plants. This "residual fertilizer" adds value to plants by extending the benefits beyond the greenhouse. A new study recommends the best fertilizer strategies to give plants staying power and add value for consumers.
In a study of older women with newly diagnosed stage I to III breast cancer, approximately one in five lost the ability to complete some of the basic tasks necessary for independent living within one year of initiating treatment. The study also found that a simple survey can help identify which women are at risk of such functional decline. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society.
