Why are there so many weeds in your garden this year?
Some years, no matter how diligently you pull, your backyard garden is always covered with weeds. Other years, with the minimum of effort, your garden remains weed-free. view more (2006-09-05)
Ironing out malnutrition
Two of the three keys are in place to unlock the secret to controlling and enhancing plant iron uptake. Scientists are poised to identify the final step in the process that could supply the world with iron-rich crops. Collaboration between American and French scientists has led to the identification of three key genes involved in iron uptake in... view more... (2001-04-02)
Plants recognize their siblings, biologists discover
The next time you venture into your garden armed with plants, consider who you place next to whom. It turns out that the docile garden plant isn't as passive as widely assumed, at least not with strangers. view more (2007-06-14)
Mediterranean Diet Could Reduce Risk Of Coronary Artery Disease In Asian Populations (P 1455)
Results of a study in this week's issue of THE LANCET highlight how the adoption of a Mediterranean-style diet could help reduce cardiovascular disease in Asian populations, especially among Asian people living in western countries. Coronary artery disease (CAD) is a major public-health problem for south Asian people-however it is not explained by... view more... (2002-11-06)
Genetic discovery could lead to drought-resistant plants
New knowledge of how plants "breathe" may help us breed and select plants that would better survive scorching summers, says a University of Toronto study. view more (2005-07-19)
MSU scientists find new gene that helps plants beat the heat
Michigan State University plant scientists have discovered another piece of the genetic puzzle that controls how plants respond to high temperatures. That may allow plant breeders to create new varieties of crops that flourish in warmer, drier climates. view more (2008-10-07)
University of Alberta and NINT researchers make solar energy breakthrough
The University of Alberta and the National Research Council's National Institute (NINT) for Nanotechnology have engineered an approach that is leading to improved performance of plastic solar cells (hybrid organic solar cells). view more (2009-02-26)
Research gaining momentum by silencing genes
Along with five European academic laboratories, researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to Ghent University are accelerating the study of the model plant Arabidopsis thaliana. Taking advantage of the new RNAi technology, they are able to study the function of genes with the aid of specially... view more... (2004-10-14)
Plants can be used to study how and why people respond differently to drugs
While prescription medications work successfully to cure an ailment in some people, in others the same dose of the same drug can cause an adverse reaction or no response at all. view more (2007-09-27)
Prairie dogs: influencing the accumulation of metals in plants?
Prairie dogs may seem like harmless little creatures, but they can inflict serious injury on plants simply by snacking on them. Plants cannot flee from their furry predators, so how do they avoid becoming a prairie dog's lunch? view more (2009-06-24)
Midget plant gets makeover
A tiny plant with a long name (Arabidopsis thaliana) helps researchers from over 120 countries learn how to design new crops to help meet increasing demands for food, biofuels, industrial materials, and new medicines. view more (2009-06-23)
Clones on task serve greater good, evolutionary study shows
"Don't ever change" isn't just a romantic platitude. It's a solid evolutionary strategy. At least if you're among the creatures that produce scads of genetically identical offspring - like microbes, plants or water fleas. These creatures provide a chance to wonder about the clones raised in near-identical environments that turn out... view more... (2007-08-14)
Landfills, chemical weapon debris possibly a good match, computer model suggests
Putting building debris contaminated by chemical weapons into municipal landfills likely would pose only a minimal risk to nearby communities and the surrounding environment, according to a study scheduled for publication in the July 1 issue of the American Chemical Society journal Environmental Science & Technology. view more (2006-06-28)
Researchers discover primer to plant defense system
By identifying a novel compound that primes a plant's immune system, researchers at Oak Ridge National Laboratory and the University of Chicago may be on a path to developing disease-resistant plants. view more (2009-04-06)
Too hot to handle! Scientists identify heat sensing regulator
Neuroscientists at Johns Hopkins are a step closer to understanding pain sensitivity - specifically why it's variable instead of constant - having identified a gene that regulates a heat-activated molecular sensor. view more (2008-05-14)
Tarantula venom and chili peppers target same pain sensor
Venom from a West Indian tarantula has been shown to cause pain by exciting the same nerve cells in mice that sense high temperatures and the hot, spicy ingredient in chili peppers. view more (2006-11-09)
Common weed could provide clues on aging and cancer
A common weed and human cancer cells could provide some very uncommon details about DNA structure and its relationship with telomeres and how they affect cellular aging and cancer, according to a team led by scientists from Texas A&M University and the University of Cincinnati (UC). view more (2009-10-27)
Chemical warfare ravages mental health of Iranian civilians
Iranian civilians exposed to high-intensity warfare and chemical weapons are experiencing significantly higher levels of psychological distress compared to those exposed to low-intensity warfare but not chemical weapons. view more (2006-08-02)
Diabetics on high-fiber diets might need extra calcium, report UT Southwestern researchers
The amount of calcium your body absorbs might depend, in part, on the amount of dietary fiber you consume. view more (2009-03-24)
Genes in the countryside? Assessing the environmental impact of genetically modified crops
Risk assessment for genetically modified crops is technically feasible by focusing on the genes and their effects on the plants and the populations of which they are a part. Combining research in natural populations, experiments with ""modified"" plants, and mathematical modelling provides important insights into the potential environmental impact... view more...
