Frogs that adapt to pesticides are more vulnerable to parasites

Amphibians can evolve increased tolerance to pesticides, but the adaptation can make them more susceptible to parasites, according to a team of scientists.

Probiotics help poplar trees clean up contaminated groundwater

Researchers have conducted the first large-scale experiment on a Superfund site using poplar trees fortified with a probiotic -- or natural microbe -- to clean up groundwater contaminated with trichloroethylene, or TCE.

Seeing a virus in action

Imaging the movement of a virus demonstrates that single-particle X- ray scattering has the potential to shed new light on key molecular processes, like viral infection, when paired with powerful new algorithms.

Killing bacteria by hacking plastics with silver and electricity

Researchers have developed an innovative way of hacking conducting plastics so as to prevent bacterial growth using silver nanoparticles and a small electrical current. The method could prove to be useful in preventing bacterial infections in hospitals.

Where is everybody? The implications of cosmic silence

If the potential for intelligent life to exist somewhere in the universe is so large, then where is everybody? In a new paper, an astrophysicist argues that species such as ours go extinct soon after attaining high levels of technology.

Trees and shrubs offer new food crops to diversify the farm

What if we could design a landscape that would provide a variety of nutritious foods, high-quality habitat, and ecosystem services, while also delivering a healthy profit to the landowner? According to researchers, it is not only possible, it should be adopted more widely, now.

Scientists map sex chromosome evolution in pathogenic fungi

Researchers recently mapped the evolutionary turning point that transformed the pathogenic Cryptococcus fungus from an organism with thousands of sexes to only two. They found that during evolution, a reshuffling of DNA known as translocation brought together separate chunks of sex-determining genes onto a single chromosome, essentially mimicking the human X or Y chromosome. Surprisingly, these translocations occurred at the chromosome's centromeres, regions so dense that they were once thought to suppress recombination.

Sweet! Sugar-coated probe yields better acid test

When our cells' acid-alkaline balance goes wrong, it can go wrong in a big way -- think cancer and cystic fibrosis. New fluorescent probes make it easier to detect pH and sweetened the deal by adding sugar to his acid-sensitive probes, making them much friendlier to living tissue.

Plastic films incorporating N-halamines could sanitize food production facilities

Specially designed plastic films can prevent bacterial contamination in the food and biomedical industries, according to new research.

Almonds may help boost cholesterol clean-up crew

Eating almonds on a regular basis may help boost levels of HDL cholesterol while simultaneously improving the way it removes cholesterol from the body, according to researchers.
