Researchers have discovered that a known quality control mechanism in human, animal and plant cells is active against viruses. They think it might represent one of the oldest defense mechanisms against viruses in evolutionary history.
There's a good chance that many of the suddenly trendy vegetables that foodies latch on to in...
At first blush it is a bit disingenuous, using beer waste as a base material for new bone. But...
On this episode of Bioscience Technology This Week, Christina Jakubowski highlights the possibility of using small sensors as biobatteries that can harvest power from sweat. Our second story covers a newly discovered plant “language."
On this episode of Bioscience Technology This Week, Christina Jakubowski reports on the possibility of making nuts safer to eat for those with allergies. Our second story tackles important questions about which genes may drive antibiotic resistance.
Black truffles expensive and highly prized in the world of haute cuisine, but in the world of epigenetics, the fungi are of major interest for another reason: their unique pattern of DNA methylation, a biochemical process that chemically modifies nucleic acids without changing their sequence.
Researchers report that dietary capsaicin– the active ingredient in chili peppers– produces chronic activation of a receptor on cells lining the intestines of mice, triggering a reaction that ultimately reduces the risk of colorectal tumors.
Scientists have discovered that a compound isolated from the plant protects cells from altered molecular pathways linked to Alzheimer’s, Parkinson’s and the neurodegeneration that often follows a stroke.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on gold nanoparticles' promise in drug delivery. Our second story examines the work being done to decipher the wheat genome and the implications of this work.
The largest study of the effects of the main ingredient of cannabis has shown definitively that it can cause short-term paranoia. The research also, for the first time, identifies psychological factors that can lead to feelings of paranoia in people who take cannabis.
Early maize farmers selected for genes that improved the harvesting of sunlight, a new detailed study of how plants use 'doubles' of their genomes reveals. The findings could help current efforts to improve existing crop varieties. Oxford University researchers captured a 'genetic snapshot' of maize as it existed 10 million years ago when the plant made a double of its genome—a 'whole genome duplication' event.
Biophysics researchers at the University of Michigan have used short pulses of light to peer into the mechanics of photosynthesis and illuminate the role that molecule vibrations play in the energy conversion process that powers life on our planet. The findings could potentially help engineers make more efficient solar cells and energy storage systems.
A new fruit that research says packs more antioxidants than popular "superfoods" like blueberries, acai berries and goji berries is establishing itself in the aisles of mainstream grocery stores, showing up in everything from juices to powdered supplements to baby food.
Ludovico Cademartiri was looking for a way to study plant and root growth that was simple, inexpensive and flexible, something that allowed experiments to be reproduced all over the world, even in labs without the latest technologies or the infrastructure required for plant science or agronomy research.
A daily supplement of an extract found in tomatoes may improve the function of blood vessels in patients with cardiovascular disease, according to new research.
Sequencing the genomes of domesticated citrus revealed a very limited genetic diversity that could threaten the crop’s survival prospects, according to a research team that analyzed and compared the genome sequences of 10 diverse citrus varieties. The findings provide insight of how citrus has been cultivated and point to how genomics-guided development could help produce crops that better resist environmental stresses and pests.
The U.S. Department of Energy Office of Science has targeted research into the common bean because of its importance in enhancing nitrogen use efficiency for sustainability of bioenergy crops, and for increasing plant resilience and productivity with fewer inputs, on marginal lands, and in the face of the changing climate and environment.
While it was known that a specific birch pollen protein causes the immune system to overreact, the exact reason why many people are allergic to birch pollen had not yet been fully clarified. Now, scientists at the Vetmeduni Vienna have discovered what makes the protein an allergen.
The intimate interaction between a plant and its environment has sent some puzzling cues to scientists trying to determine how, at the molecular level, a plant becomes infected by bacteria. At this level, researchers have found that plants sometimes beckon the bacteria in a seemingly counterintuitive action to its health.
Aquatic algae can sense an unexpectedly wide range of color, allowing them to sense and adapt to changing light conditions in lakes and oceans. Phytochromes are the eyes of a plant, allowing it to detect changes in the color, intensity, and quality of light so that the plant can react and adapt. Typically about 20 percent of a plant’s genes are regulated by phytochromes.
Scientists have identified one of the molecular pathways that resveratrol, the component of grapes and red wine associated with health benefits, uses to achieve its beneficial action.
We should eat even more vegetables than our governments— and moms— said. A recent study found that eating seven (or more) servings of veggies and fruits a day extends life by what the authors bill as a “staggering” 42 percent.
Ginseng can help treat and prevent influenza and respiratory syncytial virus (RSV), a respiratory virus that infects the lungs and breathing passages, according to new research findings.
Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. For example, little is known about how it is regulated in response to changes in light intensity. More fundamentally, we do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism.
Genetically modifying a key protein complex in plants could lead to improved crops for the production of cellulosic biofuels, a Purdue University study says. Clint Chapple, distinguished professor of biochemistry, and fellow researchers generated a mutant Arabidopsis plant whose cell walls can be converted easily into fermentable sugars but does not display the stunted growth patterns of similar mutants.
Reproductive cells, such as an egg and sperm, join to form stem cells that can mature into any tissue type. But how do reproductive cells arise? We humans are born with all of the reproductive cells that we will ever produce. But in plants things are very different. They first generate mature, adult cells and only later “reprogram” some of them to produce eggs and sperm.
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 once believed to be only 150 years old— pushing its origin back at least 2,000 years and revealing how intense farming at the time of the Crusades contributed to its spread.
