Detecting synthetic fertilizers: Is it organic or not?
As organic farming becomes more common, methods to identify fraud in the industry are increasingly important. In a recent study in Journal of Environmental Quality, scientists successfully use nitrogen isotopic discrimination to determine if non-organic, synthetic fertilizers were used on sweet pepper plants. view more (2008-02-04)
From laboratory demonstrators over systems to indispensable process plants
Today microreactors are already valuable informants for the process development in the laboratory area. According to a study of the French consulting company YOLE Développement and Institut für Mikrotechnik Mainz GmbH (IMM) the readiness of industry clients to buy such microreaction components for chemical process development rests... view more...

Nightshades: 'overflowing' with Phytophthora resistant genes?
The potato and other related varieties of the Solanum species contain scores or perhaps even hundreds of genes that can give the plant a degree of resistance to 'potato blight', a disease caused by Phytophthora infestans. This is one of the conclusions that came to light in Vivianne Vleeshouwers' thesis, with which she recently earned her doctoral... view more... (2001-02-01)
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)
Discovering the secret code behind photosynthesis
Scientists from Queen Mary, University of London have discovered that an ancient system of communication found in primitive bacteria, may also explain how plants and algae control the process of photosynthesis. view more (2009-02-25)
Sun-safe pool policies appear related to sun safety behaviors among pool staff
The social environment at swimming pools appears to be related to sun safety behaviors of outdoor pool staff, according to a report in the February issue of Archives of Dermatology, one of the JAMA/Archives journals. view more (2009-02-17)
Climate change opens new avenue for spread of invasive plants
Plants that range northward because of climate change may be better at defending themselves against local enemies than native plants. view more (2008-11-20)
Regulations for health-promoting gentech food products
Newly published report lists regulations for health-promoting gentech food products Differences between EU and US clarified A new report has been published listing the regulations for food crops and medicinal plants that contain extra health-promoting ingredients as a result of genetic modification (gentech). The document is the result of a joint... view more... (2001-12-12)
Cropland diversity reduces nitrogen pollution
Researchers have identified a link between the diversity of crops grown in farmlands and the pollution they create in lakes and rivers. view more (2009-02-11)
Plants tell caterpillars when it's safe to forage
The world is filled with cues that could influence the daily feeding patterns of an organism. Many plants, for example, respond to foraging damage by releasing specialized chemical signals-volatile organic compounds that evaporate in the air-that attract the forager's natural enemies. view more (2006-05-16)
Alarm pheromone causes aphids to sprout wings
Chemical communication within insect species is often much more sophisticated than expected. When aphids are attacked by predators such as ladybird beetles, they release an alarm pheromone, (E)-ß-farnesene, that has long been known to cause other aphids to walk around or drop from the plant. view more (2005-05-18)
How size matters
The beauty of nature is partly due to the uniformity of leaf and flower size in individual plants, and scientists have discovered how plants arrive at these aesthetic proportions. view more (2007-12-13)
When Plants Think Alike
Biologists have discovered that a fundamental building block in the cells of flowering plants evolved independently, yet almost identically, on a separate branch of the evolutionary tree--in an ancient plant group called lycophytes that originated at least 420 million years ago. view more (2008-05-28)
Predators: an overlooked player in plant-pollinator relationships
Biologists have long recognized that predators can help to shape ecological communities -- wolves promote the growth of young trees through predation on moose, otters keep kelp forests thriving by preying on sea urchins, etc. Yet we have seldom considered the consequences of predation on animals that help plants reproduce. Predation on pollinators... view more... (2003-08-13)
Environmental effects of cold-climate strawberry farming
Strawberries are America's fifth-favorite fruit, according to consumption rates. California and Florida grow more than 95% of the nation's strawberries; an additional 12,000 acres are planted in other states. view more (2009-09-08)
Organic nitrogen gives new clue to biodiversity
Scientists have found that organic nitrogen is more important for plant growth than previously thought and could contribute to maintaining diversity in grasslands. view more (2006-04-12)
Study shows hope for ridding lakes of clawed invader
The rusty crayfish-a voracious, bullying exotic that has visited ecological havoc on numerous Wisconsin lakes-may have finally met its match. view more (2006-08-01)
Annuals converted into perennials
Annual crops grow, blossom and die within one year. Perennials overwinter and grow again the following year. The life strategy of many annuals consists of rapid growth following germination and rapid transition to flower and seed formation, thus preventing the loss of energy needed to create permanent structures. view more (2008-11-10)
Why do insects like to eat some plants more than others?
In a study appearing in the forthcoming issue of The American Naturalist, Tom E. X. Miller, Andrew J. Tyre, and Svata M. Louda (all of the University of Nebraska, Lincoln) examined herbivore dynamics, specifically why plants aren't all eaten at the same rate. view more (2006-11-14)
Plants uptake antibiotics
Scientists at the University of Minnesota have been evaluating the impact of antibiotic feeding in livestock production on the environment. view more (2007-07-12)
