Chemical compounds found in cannabis, some of which also occur naturally in the body, may help...
Scientists have charted a significant signaling network in a tiny organism that's big in the...
Help yourself to some nuts this holiday season: Regular nut eaters were less likely to die of cancer or heart disease — in fact, were less likely to die of any cause — during a 30-year Harvard study.
For the worst cases of type 1 diabetes, islet transplantation already has freed hundreds of people from complete dependence on insulin and from life-threatening consequences of the disease. However, the procedure still is regarded as experimental by the U.S. Food and Drug Administration (FDA).
Enhanced extracts made from special antioxidants in spearmint and rosemary improve learning and memory, a study in an animal model has found.
Tiny amounts of a specific type of lipid in the small intestine may play a greater role than previously thought in contributing to clogged arteries. Researchers were able to reduce the negative effects of these lipids in mice by feeding them a genetically engineered tomato, designed to mimic HDL ("good") cholesterol.
Onions now come in a tearless version that scientists are now reporting could pack extra health benefits like their close relative, garlic, which is renowned for protecting against heart disease.
Blueberries are called a “superfood” for their high polyphenol content, but when baked or cooked, levels of some of these substances rise while others fall, which could alter their “super” health benefits.
Using cells from the stem of a seedling as a model system, biologists are seeking to understand the molecular mechanisms that organize and pattern the hundreds or thousands of microtubular “bones” of the plant cytoskeleton.
With estimates of losing 15 to 40 percent of the world’s species over the next four decades– due to climate change and habitat loss, researchers ponder whether science should employ genetic engineering to the rescue. The technique would involve “rescuing a target population or species with adaptive alleles, or gene variants, using genetic engineering,” say the authors of new commentary on the subject.
Genomic sequencing experts and pharmacologists revealed a striking mutational signature of upper urinary tract cancers caused by aristolochic acid, a plant compound contained in herbal remedies used for thousands of years to treat a variety of ailments such as arthritis, gout and inflammation.
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 label that reads "gluten free" will now mean the same thing for all food, regardless of which kind you buy. After more than a six-year delay, the Food and Drug Administration has set a new standard for labels that will make shopping easier for consumers on gluten-restricted diets.
Regular marijuana use in adolescence, but not adulthood, may permanently impair brain function and cognition, and may increase the risk of developing serious psychiatric disorders such as schizophrenia, according to a recent preclinical study. Researchers hope that the study will help to shed light on the potential long-term effects of marijuana use.
Newly trialed native algae species provide real hope for the development of commercially viable fuels from algae, scientists have found. The researchers have identified fast-growing and hardy microscopic algae that could prove the key to cheaper and more efficient alternative fuel production.
In older men, a natural antioxidant compound found in red grapes and other plants– called resveratrol– blocks many of the cardiovascular benefits of exercise, according to results from a recent research project. The research unusually suggests that eating a diet rich in antioxidants may actually counteract many of the health benefits of exercise.
A type of fungus coating much of the stored corn, wheat, rice and nuts in developing countries may be quietly worsening the AIDS epidemic, according to a new study. Kept in sacks piled in barns and warehouses, food stores in countries near the equator are contaminated by Aspergillus flavus and A. parasiticus, fungi that produce a toxic substance called aflatoxin.
Low doses of a psychedelic drug erased the conditioned fear response in mice, suggesting that the agent may be a treatment for post-traumatic stress disorder and related conditions, a new study found. The unexpected finding was made by a reasearch team studying the effects of the compound psilocybin on the birth of new neurons in the brain and on learning and short-term memory formation.
Paralytic drugs like succinylcholine (SC) are often used during surgery or when critically ill patients require endotracheal intubation. But if the drug is not swiftly cleared from the patient’s system, the results can be deadly. A new study shows that the plant-produced recombinant human enzyme butyrylcholinesterase (BChE) can rapidly reverse paralysis of the airways (or apnea) caused by succinylcholine.
A chemical component present in the nightshade family of plants is one of the world’s most tenaciously addictive substances. It is the nicotine contained in tobacco and found in high concentrations in cigarettes. Smoking remains a global scourge; in the U.S. it is the leading source of preventable death. Researchers have launched an ambitious new project, designed to attack nicotine dependence in a radically new way.
You say tomato, I say comparative transcriptomics. Researchers in the U.S., Europe and Japan have produced the first comparison of both the DNA sequences and which genes are active, or being transcribed, between the domestic tomato and its wild cousins.
It's common wisdom that one rotten apple in a barrel spoils all the other apples, and that an apple ripens a green banana if they are put together in a paper bag. Ways to ripen, or spoil, fruit have been known for thousands of years. Now, scientists have traced the thousands of genes in a plant that are activated once ethylene gas is released.
The only truly practical biofuels will be those made from abundant feedstocks like switchgrass, wheat straw and other woody plants, whose cell walls consist of lignocellulose. After pretreatment to remove or reduce the lignin, the sugary remains of cellulose and hemicellulose are fermented by microorganisms to yield the biofuel.
Forest fires are powerful, highly destructive events that while being life altering also have come to be appreciated for their clearing effects, from which explosive new forest growth evolves. But why does the forest respond in this way to such a dramatic event, and what triggers the natural growth that follows? Is there some sort of communication among plants to signal that the coast is clear for growth?
Two processes that turn woody biomass into transportation fuels have the potential to exceed current Environmental Protection Agency (EPA) requirements for renewable fuels, according to new research. The EPA’s standard for emissions from wood-based transportation fuels requires a 60 percent reduction in greenhouse gas emissions compared to using fossil fuels.
Extremely low doses of marijuana's psychoactive component protect brain before and after injury, says new research. Though marijuana is a well-known recreational drug, extensive scientific research has been conducted on the therapeutic properties of marijuana in the last decade.
Field workers at an Eastern Oregon wheat farm were clearing acres for the bare offseason when they came across a patch of wheat that didn't belong. The workers sprayed it and sprayed it, but the wheat wouldn't die. Their confused boss grabbed a few stalks and sent it to a university lab in early May.
