Curtin University researchers have found a way to breed disease-resistant wheat with no downside, potentially bringing multi-million dollar savings to Australia’s agricultural industry. According to John Curtin Distinguished Professor Richard Oliver, Director of the Australian Centre for Necrotrophic Fungal Pathogens at Curtin, farmers can lose more than 0.35 tonnes per hectare in wheat yields to Yellow Spot, even after applying fungicide.
Scientists have for the first time sequenced an ancient RNA genome—of a barley virus...
Nuts are in the news: a recent study has offered evidence for a big reason our bodies...
To safely use bacteria in agriculture to help fertilize crops, it is vital to understand the...
Following its recent synonymisation with Meloidogyne ulmi, a species known to parasitize elm trees in Europe, it has become clear that M. mali has been in the Netherlands for more than fifty years. Evidences given by the authors suggest that M. mali was probably introduced during the breeding program on Elms against the Dutch Elm Disease (DED).
Scientists at the University of York have made a significant step in the search to develop effective second generation biofuels. Researchers from the Department of Chemistry at York have discovered a family of enzymes that can degrade hard-to-digest biomass into its constituent sugars.
Using the largest dated evolutionary tree of flowering plants ever assembled, a new study suggests how plants developed traits to withstand low temperatures, with implications that human-induced climate change may pose a bigger threat than initially thought to plants and global agriculture.
Teens who were heavy marijuana users- smoking it daily for about three years- had abnormal changes in their brain structures related to working memory and performed poorly on memory tasks, according to a new study.
In a seemingly simple experiment, a scientist exposes rats to a certain pesticide over several days, and the rodents start showing symptoms remarkably similar to those seen in Parkinson’s patients.
Chemical compounds found in cannabis, some of which also occur naturally in the body, may help to reduce brain damage following a stroke, new research has revealed.
Scientists have charted a significant signaling network in a tiny organism that's big in the world of biofuels research.
A team of scientists looking into the interplay of the immune system and cancer have found a link between a history of airborne allergies– in particular to plants, grass and trees– with risk of blood cancers in women.
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.
