Emission choices lead to starkly different futures for Northeast agriculture, says CU expert at briefing
Farmers will be the first to feel the heat from global warming as they grapple with new and aggressive crop pests, summer heat stress and other sobering challenges that could strain family farms to the limit, warns David Wolfe, a Cornell expert on the effects of climate change on agriculture. view more (2007-07-12)
Glue made from ethanol-production leftovers may be worth more than the fuel itself
Mixing up a batch of ethanol from alfalfa or switchgrass isn't nearly as efficient as creating it from corn, but that doesn't mean growing grass crops for fuel won't pay, says Paul Weimer. view more (2006-09-28)
Can we keep the cap on transgene escape?
Molecular strategies are being developed to impede the escape of transgenes from transgenic crops into wild relatives, which might become invasive upon acquiring transgenic traits such as resistance to pests or herbicides. For example, to impede escape through pollen, a transgene could be inserted into chloroplast DNA, which in many crops is... view more... (2004-02-24)
'Killer spices' provide eco-friendly pesticides for organic fruits and veggies
Mention rosemary, thyme, clove, and mint and most people think of a delicious meal. Think bigger-acres bigger. view more (2009-08-17)
Some biofuels might do more harm than good to the environment, study finds
Biofuels based on ethanol, vegetable oil and other renewable sources are increasingly popular with government and environmentalists as a way to reduce fossil fuel dependence and limit greenhouse gas emissions. view more (2008-05-28)
Toll of climate change on world food supply could be worse than thought
Global agriculture, already predicted to be stressed by climate change in coming decades, could go into steep, unanticipated declines in some regions due to complications that scientists have so far inadequately considered, say three new scientific reports. view more (2007-12-04)
Biotech cotton provides same yield with fewer pesticides
Arizona farmers receive the same yield/acre, use fewer chemical insecticides and maintain insect biodiversity when they plant the biotech cotton known as Bt cotton, according to new research. view more (2006-05-02)
How purple corn and RNA break genetic laws
A newly cloned gene in corn will help explain how unusual interactions between a parent's genes can have lasting effects in future generations. The finding has implications for breeding better crop plants and unraveling complex genetic diseases. view more (2006-07-20)
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)
Repel the aphids and you attract the leafhoppers
Things don`t always turn out as you expect when you play with genes AN ATTEMPT to make potato plants resistant to sap-sucking insects has highlighted the unpredictability of genetic engineering. The modified plants unexpectedly turned out to be vulnerable to other kinds of insect pests, demonstrating how important it is to assess each transgenic... view more... (2002-05-29)
Chemical exchanges show wasps are bad losers
Wasps have more than just a sting in their tail according to new research published this week in the Proceedings of the Royal Society B, they also carry the insect version of pepper spray in their heads, which they can release when fighting other wasps. view more (2006-11-20)
Trained wasps may be used to detect bombs, bugs, bodies and more
An unusual device that uses trained wasps, rather than trained dogs, to detect specific chemical odors could one day be used to find hidden explosives, plant diseases, illegal drugs, cancer and even buried bodies, according to a joint study by researchers at the University of Georgia and U.S. Department of Agriculture. view more (2005-10-21)
New research shows folic acid in grains has reduced birth defects
Folic acid fortification of grain foods has produced a one-third decline in serious birth defects of the brain and spine, but the March of Dimes urged federal officials to help spare a greater number of babies from these devastating conditions by requiring higher levels of the B vitamin. view more (2005-09-06)
Feeling itchy?
Just when you thought it was safe to go to bed, the bed-bug is returning to UK cities. Many urban infesting organisms are in decline. Worryingly, the bed-bug is bucking this trend. One London borough has seen infestations increase nearly ten-fold in the last ten years. Bed-bugs are not known to spread any diseases, but their bites are a severe... view more... (2004-04-02)
Iowa State professor's research shows Midwest forests losing diversity, complexity
Forests in the nation's Upper Midwest have changed greatly since the time of the early settlers. And more changes may be coming. view more (2007-10-17)
Dutch ecologists plea for scientific research to aid risk assessment
A survey among nine prominent Dutch ecologists has identified gaps in knowledge on the potential effects of Bt-crops on food chains and ecosystems. Bt-crops have been modified to express a bacterial gene that codes for a toxin that kills certain groups of insects. The toxin is continuously produced in all plant tissues and target as well as... view more... (2003-08-28)
Important rice production system under pressure
In the face of growing pressure on one of Asia's most important food production systems, experts are warning that farmers must get more help to make them more efficient. view more (2007-10-10)
Two-step chemical process turns raw biomass into biofuel
Taking a chemical approach, researchers at the University of Wisconsin-Madison have developed a two-step method to convert the cellulose in raw biomass into a promising biofuel. view more (2009-02-11)
Chasing high flying insects with radar
New developments to vertical looking radar (VLR) mean that scientists at Rothamsted, Harpenden are now tracking insects to find out where they go and how they behave when they take to the skies. "The sheer abundance of insects is amazing," says Dr Alan Smith of Rothamsted Radar Entomology Unit. "The actual biomass of insects above us on a... view more... (2002-06-26)
Research leads to healthful strategies for re-setting the body's clock
Everyone is equipped with a biological clock, a region in the brain the size of a corn kernel, which dictates our sleep-wake cycles, and plays a major role in our physical and mental health. view more (2006-03-23)
