Dogs, maybe not, but old genes can learn new tricks
A popular view among evolutionary biologists that fundamental genes do not acquire new functions was challenged this week by a new study in the Proceedings of the National Academy of Sciences. view more (2009-05-12)
In a bug-eat-bug world, researchers are using a unique Chinese import to battle soybean aphids
University of Minnesota scientists are field testing a beneficial insect, a stingless wasp from China also known as Binodoxys communis, that kills soybean aphids. A successful field test would be a major breakthrough in controlling a damaging crop pest. view more (2007-07-25)
Causative gene for human "lobster claw" syndrome identified
A new study using mouse "knockouts" shows that genes that control limb formation in insects have similar functions in mammals. Split hand/foot malformation (SHFM) or ectrodactyly (the "lobster claw" anomaly), is a severe congenital malformation syndrome characterised by a profound median cleft of the hands and/or feet, typically associated with... view more...

Defeating the 'superpests'
Scientists have developed a new technique that makes pesticides more effective by removing insects' ability to exhibit resistance. view more (2005-10-10)
Remembrance of things past influences how female field crickets select mates
UC Riverside biologists researching the behavior of field crickets have found for the first time that female crickets remember attractive males based on the latter's song, and use this information when choosing mates. view more (2009-04-22)
Detecting disease in greenhouse plants
Greenhouses are an integral part of U.S. agriculture. Nearly $200 million of food is produced in domestic greenhouses each year, and the facilities play a vital role in producing seeds and transplantable vegetation. Understanding how to keep greenhouse plants healthy can translate to increased revenue for producers. view more (2009-02-18)
Link between sunspots, rain helps predict disease in east Africa
The research, conducted by paleoclimatologist Curt Stager of Paul Smith's College in Paul Smiths, N.Y. and colleagues, can be used by public health officials to increase measures against insect-borne diseases long before epidemics begin. view more (2007-08-08)
Discovery in amber reveals ancient biology of termites
The analysis of a termite entombed for 100 million years in an ancient piece of amber has revealed the oldest example of "mutualism" ever discovered between an animal and microorganism, and also shows the unusual biology that helped make this one of the most successful, although frequently despised insect groups in the world. view more (2009-05-15)
Sex is thirst-quenching for female beetles
Female beetles mate to quench their thirst according to new research by a University of Exeter biologist. The males of some insect species, including certain types of beetles, moths and crickets, produce unusually large ejaculates, which in some cases can account for around 10% of their body weight. view more (2007-08-29)
Pesticides disrupt farmland bird food chains
Preliminary results are emerging from important new work on the indirect effects of agricultural pesticides on farmland birds in Britain. At the British Ecological Society`s Winter Meeting, at the University of Warwick on 18–20 December 2001, Tony Morris of the Royal Society for the Protection of Birds (RSPB) will present early evidence from... view more...

Biomimetics: Transferring Technology From Nature - Philosophical Transactions Of The Royal Society A Vol. 360, No. 1791 - Cover Date 15 February 2002
Biomimetics - natural design This issue of Transactions A, a Royal Society journal, addresses the emerging and vibrant multidisciplinary field of biomimetics. The idea that natural systems may have design elements that can be used in manufactured technology is not new, Leonardo da Vinci based many of his inventions on natural mechanisms, and more... view more...

Study explores effects of herbicide drift on white oak
Herbicide drift, which occurs when pesticides "drift" from the targeted application area to a nearby non-targeted area, is a particular concern in Midwestern regions of the United States. view more (2009-03-26)
Researchers to study rebirth of an island after volcanic eruption
When Alaska's Kasatochi Volcano erupted on Aug. 7, 2008, it virtually sterilized Kasatochi Island, covering the small Aleutian island with a layer of ash and other volcanic material several meters thick. view more (2009-08-07)
To deter a predator, kill its young!
Prey have evolved a suite of tricks to avoid falling victim to a predator. They may escape, hide, protect, become toxic/inedible or defend themselves. In principle, they could also scare the predator away, but this is risky when predators are big. Recent work led by a Dutch research team and published in the July issue of Ecology Letters revealed... view more... (2002-07-11)
Leicester research paves way for first use in Europe of an insect to fight invasive plant
Researchers at the University of Leicester have paved the way for the first ever use in Europe of an insect (biocontrol) to combat an invasive plant species in Britain. view more (2009-07-31)
Accessory protein determines whether pheromones are detected
Pheromones are like the molecules you taste as you chomp on a greasy french fry: big and fatty. view more (2007-10-18)
New designer toxins kill Bt-resistant insect pests
A new way to combat resistant pests stems from discovering how the widely used natural insecticide Bt kills insects. view more (2007-11-02)
Perennial wheat research looks at options for producers
Perennial wheat? The possibility is being looked at by a Texas Agricultural Experiment Station researcher. view more (2006-11-29)
Bacillus thuringiensis - Bacterial Insecticide
Microbiologists in Europe have played a major role in developing the Bacillus thuringiensis story, as they have in many areas of research. FEMS, The Federation of European Microbiological Societies, is now embarking on a series of major European Congresses bringing together scientists from all parts of Europe and providing a forum for the... view more...

Mom was right: Nice guys don't always finish last
Picture it: One jerk in a bar spends the night delivering bad come-ons to women. By the end of the evening, the women aren't receptive to even the nicest guys around. view more (2009-11-06)
