The researchers point to mounting evidence of the evolution of pest resistance to Bt cotton suggesting that the value of bat pest control services may increase again.
This evidence of resistance evolution suggests that Bt cotton may not be a long-term solution to pest-related losses said Mccracken.
In fact by preying on the individual insects that survive the Bt toxin bats may provide the additional service of slowing the evolution of resistance to Bt and other insecticides.

studies showa large body of literature has shown that genetically-modified plants that produce proteins from the bacterium Bacillus thuringiensis (Bt) to protect themselves from insect pests have little to no effect on a wide range of nontarget insects.
However concerns about Bt crops still exist. Now two new studies using more exacting methods show that Bt crops have no negative effects on two beneficial insect predators or on a beneficial entomopathogenic nematode.
In an article in the February 2014 issue of Environmental Entomology called Using Resistant Prey Demonstrates that Bt Plants Producing Cry1ac Cry2ab
and Cry1f Have No Negative Effects on Geocoris punctipes and Orius insidiosus researchers used caterpillars that were known to be resistant to Bt proteins and fed them Bt maize and Bt cotton.
They then fed the caterpillars to two common beneficial predatory insects--insidious flower bugs (Orius insidiosus)
and big-eyed bugs (Geocoris punctipes)--for two generations and compared them to another group of predators that consumed caterpillars fed on non-Bt plants.
and fertility of the insect predators in both groups were similar regardless of whether they consumed caterpillars that fed on Bt plants or non-Bt plants.
This research demonstrates that the current Bt proteins used in corn and cotton crops globally do not harm Geocoris punctipes
By using caterpillars resistant to the Bt proteins in this study we were able to remove any'host quality effects'that might have led to spurious misinterpretation of the results.
This work demonstrated that the caterpillars consumed the Bt proteins and the predators consumed the Bt proteins
when they fed on the caterpillars but they did not suffer any harm even over multiple generations.
when it ingested another Bt protein. For this study resistant caterpillars were fed Bt broccoli and then exposed to Heterorhabditis bacteriophora a beneficial nematode that preys on insects.
The researchers found that the virulence reproductive potential and time of emergence of the nematodes that consumed Bt-fed caterpillars were affected not significantly compared to nematodes that did not ingest the Bt protein.
This is the first report we are aware of in which a nematode predator has been tested in such detail against a Bt protein Dr. Shelton said.
Together these two studies add to the scientific literature demonstrating that Bt plants can control targeted insect pests
while not harming important natural enemies that help suppress pest species and maintain biodiversity in agricultural systems Shelton added.

and efficiency of excited hot electrons drawn from gold nanoparticles into a sheet of graphene. It's a good thing for scientists
Dark-field scattering and photoluminescence spectroscopy of more than 200 nanoparticles helped them determine that it takes about 160 femtoseconds (quadrillionths of a second) for an electron to transfer from the particle to highly conducting graphene the single-atom-thick form of carbon.
The researchers placed gold nanorods on beds of both inert quartz and highly conductive graphene and used a spectrometer to view the line width of the plasmon-scattering spectrum.
The Rice researchers found graphene broadened the nanorods'surface plasmon response --and shortened its lifetime--by accepting hot electrons.
By acting as an electron acceptor the graphene accelerated damping of the plasmons. The difference in damping between the quartz
and graphene samples provided a means to calculate the electrons'transfer time. The plasmon resonance is determined by the size
which in this case is graphene. The Rice lab hopes to optimize the connection between the nanoparticles
and graphene or another substrate preferentially a semiconductor that will allow them to trap hot electrons.

and efficacy of oral tablets used to treat ragweed allergy symptoms. The committee is likely to approve these tablets which will mark great improvement in the fight against allergy said allergist Michael Foggs MD president of the American College of Allergy Asthma and Immunology (ACAAI.
Once the committee and then the FDA approve the tablets allergy sufferers will have another form of treatment available to them.
In December the same committee granted approval for grass allergy tablets. Assuming the committee also approves the ragweed allergy tablets the FDA will then have to approve both the grass
and ragweed tablets before they can be made available to allergy sufferers. Currently the best treatment for those with moderate-to-severe allergy symptoms is allergy shots also known as immunotherapy.
This treatment requires tiny injections of purified allergen extracts. A pill a day may seem more appealing than getting shots.
So why bother with allergy shots anymore? Allergy sufferers are typically allergic to more than one allergen said Dr. Foggs.

and pollutantsspider webs actively spring towards prey thanks to electrically-conductive glue spread across their surface Oxford university scientists have discovered.
They also showed that the glue spirals can distort Earth's electric field within a few millimetres of the web
which may enable insects to spot the webs with their antennae'e-sensors'.'The study published in Naturwissenschaften shows how a quirk of physics causes webs to move towards all airborne objects regardless of
whether they are positively or negatively charged. This explains how webs are able to collect small airborne particles so efficiently and why they spring towards insects.
According to the researchers common garden spider webs around the world could be used for environmental monitoring as they actively filter airborne pollutants with an efficiency comparable to expensive industrial sensors.'
'The elegant physics of these webs make them perfect active filters of airborne pollutants including aerosols
and pesticides'said Professor Fritz Vollrath of Oxford university's Department of Zoology who led the study.'
'Electrical attraction drags these particles to the webs so you could harvest and test webs to monitor pollution levels--for example to check for pesticides that might be harming bee populations.'
'Even more fascinating you would be able to detect some airborne chemicals just by looking at the shape of the webs!
Many spiders recycle their webs by eating them and would include any particles and chemicals that are drawn electrically to the web.
We already know that spiders spin different webs when on different drugs for example creating beautiful webs on LSD and terrible webs on caffeine.
As a result the web shapes alone can tell us if any airborne chemicals affect the animal's behaviour.'
'Working with Dr Donald Edmonds from Oxford university's Department of physics Professor Vollrath showed that webs like that of the garden cross spider also cause local distortions in Earth's electric field
since they behave like conducting discs. Many insects are able to detect small electrical disturbances including bees that can sense the electric fields of different flowers and other bees.'
'Pretty much all flying insects should be capable of sensing electrical disturbances'said Professor Vollrath.''Their antennae act as'e-sensors
'when the tips are connected to the body by insulating materials meaning the charge at the tip will be different from the rest of the insect.
whether they might also use them to avoid webs and thus becoming dinner.''Electrical disturbances caused by spider webs are ranged extremely short so it is not yet clear
whether insects would be able to sense them before the web snaps out to grab them.
