The World Food Prize Foundation is confronting both opposition to genetically modified crops and the divisive issue of global warming as it gathers this week. The Foundation is awarding this year's prize to three biotechnology pioneers, infuriating environmental groups and others opposed to large-scale farming.
New research explains how a synthetic gene module controlled by the happiness hormone dopamine produces an agent that lowers blood pressure, opening up new avenues for therapies.
Scientists have discovered key details of a brain-to-body signaling circuit that, when activated by combined signals from the neurotransmitters serotonin and adrenaline, enables roundworms to lose weight independently of food intake.
New research has revealed a set of cells in the fruit fly brain that respond specifically to food odors. The degree to which these neurons respond when the fly is presented different food odors can predict how much the flies will like a given odor.
Sixty years ago scientists could electrically stimulate a region of a mouse’s brain causing the mouse to eat, whether hungry or not. Now, researchers have pinpointed the precise cellular connections responsible for triggering that behavior.
Contrary to earlier studies, new research suggests that omega-3 fatty acids may not benefit thinking skills. Omega-3s are found in fatty fish such as salmon and in nuts. The study involved 2,157 women age 65 to 80 who were given annual tests of thinking and memory skills for an average of six years and were also tested for the amount of omega-3s in their blood.
Here’s some news worth spreading: Girls who eat more peanut butter could improve their breast health later in life. Research shows that girls ages 9 to 15 who regularly ate peanut butter or nuts were 39 percent less likely to develop benign breast disease by age 30.
Carbonation, an essential component of popular soft drinks, alters the brain’s perception of sweetness and makes it difficult for the brain to determine the difference between sugar and artificial sweeteners, according to new research. The study also identifies that there is a downside to this effect.
In an analysis of 446 compounds for their the ability to boost the innate immune system in humans, researchers discovered just two that stood out from the crowd– the resveratrol found in red grapes and a compound called pterostilbene from blueberries.
The process of glycosylation, where sugar molecules are attached to proteins, has long been of interest to scientists, particularly because certain sugar molecules are present in very high numbers in cancer cells. It now turns out that these sugar molecules are not only present, but actually aid the growth of the malignant cells.
The citrus flavor and aroma of grapefruit—already used in fruit juices, citrus-flavored beverages, and prestige perfumes and colognes—may be heading for a new use in battling mosquitoes, ticks, head lice and bedbugs thanks to a less expensive way of making large amounts of the once rare and pricey ingredient
For the first time, it has been shown that an intensively active lifestyle can “completely prevent” bad diets from impairing sexual function, says a Johns Hopkins University urology fellow. Put another way, a recent rat study offers strong evidence that erectile dysfunction (ED) is more than just a bedroom bother. It may be one’s own natural biomarker for coronary artery disease.
A magical hydrating beer that minimizes hangover has been brewed, Australian researchers say. By adding electrolytes, a natural body chemical and a common sports drink ingredient, the merry Aussies say they have minimized the dehydration side effects of the beverage.
The world’s most expensive coffee can cost $80 a cup, and scientists now are reporting development of the first way to verify authenticity of this crème de la crème, the beans of which come from the feces of a Southeast Asian animal called a palm civet.
Genetics may play a role in how people's taste receptors send signals, leading to a wide spectrum of taste preferences, according to Penn State food scientists. These varied, genetically influenced responses may mean that food and drink companies will need a range of artificial sweeteners to accommodate different consumer tastes.
Your morning cup of tea or coffee may be doing more than just perking you up before work. An international team of researchers led by Duke-NUS Graduate Medical School (Duke-NUS) and the Duke University School of Medicine suggest that increased caffeine intake may reduce fatty liver in people with non-alcoholic fatty liver disease (NAFLD).
A gene variant strongly associated with development of type 2 diabetes appears to interact with a Mediterranean diet pattern to prevent stroke, report researchers. Their results are a significant advance for nutrigenomics, the study of the linkages between nutrition and gene function and their impact on human health, particularly chronic disease risk.
When mice ate a diet of 25 percent extra sugar– the mouse equivalent of a healthy human diet plus three cans of soda daily– females died at twice the normal rate and males were a quarter less likely to hold territory and reproduce, according to a newly developed toxicity test.
Drinking two cups of hot chocolate a day may help older people keep their brains healthy and their thinking skills sharp, according to a new study. The study involved 60 people with an average age of 73 who did not have dementia and who drank two cups of hot cocoa per day for 30 days.
A sleepless night makes us more likely to reach for doughnuts or pizza than for whole grains and leafy green vegetables, suggests a new study that examines the brain regions that control food choices. The findings shed new light on the link between poor sleep and obesity.
Patients with celiac disease who had persistent intestine damage (identified with repeat biopsy) had a higher risk of lymphoma than patients whose intestines healed, according to a new study. The damage is due to a reaction to eating gluten, which is found in wheat, barley and rye.
Research suggests that we all smell different smells thanks to our genes. Scientists tested nearly 200 people for their sensitivity to ten different flavors that occur in food and have identified some of the genetic differences that determine an individual’s ability to smell various odors.
A new study suggests that mothers who breastfeed run a lower risk of developing Alzheimer’s, with longer periods of breastfeeding further reducing the risk. The report suggests that the link may be to do with certain biological effects of breastfeeding.
Two volunteers who participated in the first public frying of hamburger grown in a lab say that it had the texture of meat but was short of flavor because of the lack of fat. A research team in the Netherlands developed the burger, which was grown in a laboratory from stem cells of cattle.
Donna Heller thought she had cancer. But multiple visits to the doctor after a month with debilitating nausea and diarrhea didn't yield any answers. Convinced she was dying, she met with her lawyer to get her will in order. Then she saw a television report about an outbreak of cyclospora possibly linked to bagged salad mix.
