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.
ANN ARBOR--On Charles Darwin's 207th birthday, a new study of evolution in a diverse group of wild tomatoes is shedding light on the importance of genetic variation in plants.
The work, reported today in the journal PLoS Biology, uses genome-wide sequencing to reveal details about the evolutionary mechanisms that drove genetic divergence in 13 species of wild tomatoes that share a recent common ancestor.
First author of the study is University of Michigan postdoctoral fellow James Pease, who conducted the work for his doctoral dissertation at Indiana University. The in-depth genetic analysis was led by IU's Leonie Moyle.
Lincoln, Neb., Feb. 12, 2016 -- Amid the season known for transforming Nebraska into an outdoor ice rink, a University of Nebraska-Lincoln-led research team has predicted a new molecular form of the slippery stuff that even Mother Nature has never borne.
The proposed ice, which the researchers describe in a Feb. 12, 2016 study in the journal Science Advances, would be about 25 percent less dense than a record-low form synthesized by a European team in 2014.
If the ice can be synthesized, it would become the 18th known crystalline form of water -- and the first discovered in the United States since before World War II.
A new survey finds that 15 percent of U.S. adults (that's about 36 million people) cook in the nude. Or at least have.
Meanwhile, 20 percent of Americans say someone who is a good cook turns them on the most while 19 percent are most turned on by a nice body. Good luck finding those two together. Gender roles no longer apply, 85 percent of Americans say both the man and woman do the cooking in a relationship, according to an online survey commissioned by HelloFresh, a meal kit delivery company. The sample was 1,007 adults, 18 to 70 years old, living in the continental U.S., and conducted by CARAVAN® Survey, January 14-17, 2016.
New research shows that promotional messages that use alliteration - the phonetic overlap of the beginnings of words - hold a greater appeal for consumers than non-alliterative messages, even accounting for cost differences.
In "Alliteration Alters: Phonetic Overlap in Promotional Messages Influences Evaluations and Choice," to published in the March 2016 issue of the Journal of Retailing, Marketing Professors Derick F. Davis of the University of Miami's School of Business Administration; Rajesh Bagchi of the Pumplin College of Business at Virginia Tech; and Lauren G. Block of the Zicklin School of Business at Baruch College demonstrate that even alliterative promotional messages that are read, rather than heard, prompt purchasers to prefer them.
Massachusetts General Hospital (MGH) investigators may have uncovered a novel mechanism behind the ability of obesity to promote cancer progression. In their report published online in the journal Clinical Cancer Research, the research team describes finding an association between obesity and an overabundance of a factor called PlGF (placental growth factor) and that PlGF's binding to its receptor VEGFR-1, which is expressed on immune cells within tumors, promotes tumor progression. Their findings in cellular and animal models, as well as in patient tumor samples, indicate that targeting the PlGF/ VEGFR-1 pathway may be particularly effective in obese patients.
Smoking cigarettes dramatically increases a person's risk for a host of diseases. The nicotines is addiction but it's the hundred other chemicals in cigarette smoke that are toxic.
Because e-cigarettes are simply diluted nicotine vapor, no cigarette smoke, they should be less harmful. The U.S. Food and Drug Administration (FDA) classifies many liquid flavorings in e-cigarettes as "Generally Recognized as Safe," for oral consumption. Though it sounds like waffling, that is the default categorization.
How is climate change being taught in American schools? Is it being taught at all? And how are teachers addressing climate change denial in their classrooms, schools, and school districts?
Until today's release of NCSE's comprehensive nationwide survey, no one knew. The survey, conducted in concert with the respected nonpartisan Penn State University Survey Research Center, grilled over 1500 middle and high school science teachers. The results may floor you.
After more than half a decade of speculation, fabrication, modeling and testing, an international team of researchers led by Drexel University's Dr. Yury Gogotsi and Dr. Patrice Simon, of Paul Sabatier University in Toulouse, France, have confirmed that their process for making carbon films and micro-supercapacitors will allow microchips and their power sources to become one and the same.
Feb. 11, 2016 - Social support has well-known benefits for physical and mental health. But giving support -- rather than receiving it -- may have unique positive effects on key brain areas involved in stress and reward responses, suggests a study in Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society. The journal is published by Wolters Kluwer.
ANN ARBOR, Mich. -- They may dream of becoming doctors, and helping people like themselves.
But for young people with disabilities, that dream may die when they check the admissions standards of most medical schools, according to a new study.
Even if the schools would actually consider their application, and offer them assistance as required by the Americans with Disabilities Act, they wouldn't know that from looking at many schools' websites, the researchers find.
PHILADELPHIA -- (Feb. 11, 2016) -- When it comes to our immune system, dendritic cells serve as a sort of lighthouse for T-cells. These specialized immune cells break down cancer cells into smaller pieces known as antigens. Once this happens, they can signal white blood cells that are now able to recognize these matching antigens in cancer cells and respond appropriately.
Scientists have developed a new approach that could eventually be used to treat Duchenne muscular dystrophy, using CRISPR/Cas9 to correct genetic mutations that cause the disease.
