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.

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.
Nuts are in the news: a recent study has offered evidence for a big reason our bodies are so nuts for nuts. They are apparently almost all our big brains needed to survive— thus almost all we ate— from 1.4 to 2.4 million years ago.
To safely use bacteria in agriculture to help fertilize crops, it is vital to understand the difference between harmful and healthy strains. But can the microbial good and evil be told apart? Yes, life scientists and an international team of researchers report.
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.
