Genome of yellow fever/dengue fever mosquito sequenced

... might take the form of a genetic control, such as using TEs to carry a gene into the genome that would make the mosquito resistant to the virus and stop its role as a vector for disease. Although that scenario is challenging, the payoff is potentially great, Tu said. "By introducing TEs in a more or l...

No magic tomato? Study breaks link between lycopene and prostate cancer prevention

...ry intake of more than 25 tomato-based foods, also using data from the PLCO trial, and found no overall association between lycopene intake and prostate cancer. In their current study, the researchers followed over 28,000 men between the ages of 55 and 74, enrolled in the PLCO Trial, with no history of...

Study of protein folds offers insight into metabolic evolution

...d developmental biology Jay E. Mittenthal. "We are using the techniques of phylogenetic analysis that systematicists used to build the tree of life, and we are applying it to a biochemical problem, a systems biology problem." To get at the roots of protein evolution, the researchers examined metabolic p...

Cornell lab confirms deadly fish virus spreading to new species

...fish by airborne or terrestrial predators, anglers using infected bait minnows, contaminated fishing equipment or live water wells in boats, boating activities and ballast water. "Basically, we don’t know how it got here, but it is here and it’s spreading," said Bowser. "It would be wonderful if we did k...

Biodegradable microspheres deliver time release vaccines, stimulate different immune response

A new vaccine delivery system using microspheres of a biodegradable polymer may not only reduce the need for booster shots in some cases, but also appears to stimulate an immune response that traditional vaccines do not. Researchers from Iowa State University report their findings tod...

Deconstructing brain wiring, one neuron at a time

...t green. While these experiments were conducted using slices of brain, it is possible to produce transgenic mice that will express specific genes in a targeted class of neurons, Callaway says. "All neurons of the type we select will then express the avian viral receptor and the rabies virus protein, all...

NIAID expands capability for influenza research and surveillance

... the effectiveness of annual immunization programs using inactivated or weakened (live, attenuated) flu virus vaccines. The Rochester center also will perform clinical immunological studies to better define human immune responses to influenza vaccination and infection. Additionally, the center will study h...

Researchers wake up viruses inside tumors to image and then destroy cancers

...olabeled chemical (FIAU), which can then be imaged using a gamma camera. "To perform molecular-genetic imaging, we have always had to infect cells with active herpes simplex virus so that they can replicate, express TK, and only then could we use the FIAU tracer to make the cells light up," Pomper says...

Discovery of new cave millipedes casts light on Arizona cave ecology

...ty, is also developing methods for detecting caves using thermal remote sensing imagery. Once procedures are developed, these techniques ultimately will be used to find caves on Mars. He is also studying extreme cave-adapted life forms by characterizing their habitats to determine how they exist in the nut...

Fish extinctions alter critical nutrients in water, study shows

...ens when a species dies out. Now, a Cornell study using computer simulations has teased out how the disappearance of a freshwater fish can affect the availability of certain nutrients that other species rely on. Algae, at the base of the food chain, for example, rely on fish to cycle back into the water...

It's never too late to get it back! Aging interrupted

...this also includes anti-cancer effects. They are using this knowledge to establish a novel screening technique to find drugs which mimic this longevity effect. “Right now, there are no authentic “anti-ageing drugs?capable of extending the lifespan of healthy people. The technique we have developed allows...

Genome sequencing reveals key to viable ethanol production

...ore effective than traditional methods. Instead of using separate steps to break down biomass into glucose and ferment the glucose into ethanol, as is currently done, Wu is working on a way to make a bacterium break down and ferment plant biomass efficiently in just one step. Wu investigated C. thermocel...

In young mice, gregariousness seems to reside in the genes

... lead author of the new study, which was conducted using two different strains of young mice, one gregarious in nature, the other much less so. "Their motivation to engage others varies with their genetic background; it appears to affect how young mice approach social situations." The inbred strains of ...

Flies don't buzz about aimlessly!

... question. Fruit flies explore their environment using a series of straight flight paths punctuated by rapid 90° body-saccades. Some of these manoeuvres avoid obstacles in their path. But many others seem to appear spontaneously. Are the spontaneous flight paths really random, do they serve any real purp...

Natural antibiotics yield secrets to atom-level imaging technique

... Baltimore, Md. Ramamoorthy's research group is using solid-state NMR to explore the germ-killing properties of natural antibiotics called antimicrobial peptides (AMPs), which are produced by virtually all animals, from insects to frogs to humans. AMPs are the immune system's early line of defense, batt...
