Entomologist sheds light on 250-year-old mystery of the German cockroach      (via sciencedaily.com)     Original source 

Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an outdoor-living species in Asia.

'Invisible tweezers' use robotics and acoustic energy to achieve what human hands cannot      (via sciencedaily.com)     Original source 

Undergoing surgery is seldom a pleasant experience, and it can sometimes be highly invasive. Surgical procedures have evolved steadily over the centuries, growing with the knowledge of anatomy and biology. Innovative methods have also been bolstered with new tools, and a growth in the use of robotics since the 1980s has moved health care forward significantly.

High H5N1 influenza levels found in mice given raw milk from infected dairy cows      (via sciencedaily.com)     Original source 

Mice administered raw milk samples from dairy cows infected with H5N1 influenza experienced high virus levels in their respiratory organs and lower virus levels in other vital organs, according to new findings. The results suggest that consumption of raw milk by animals poses a risk for H5N1 infection and raises questions about its potential risk in humans.

Controlling water, transforming greenhouse gases      (via sciencedaily.com)     Original source 

Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.

Observing mammalian cells with superfast soft X-rays      (via sciencedaily.com)     Original source 

Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.

Designing a better nest to help endangered turtles      (via sciencedaily.com)     Original source 

With Ontario's eight species of turtles considered at risk, a new nest designed by researchers has the potential to significantly bolster their struggling populations. The habitat is the first designed for turtles in rock barren landscapes, such as the research site around Georgian Bay. It uses moss and lichen. The researchers found that the design provided a more stable environment for incubating eggs compared to natural sites, where the probability of an egg hatching was only 10 per cent compared to 41 per cent in the created site.

Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought      (via sciencedaily.com)     Original source 

Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought to the disturbances from humans. The small whales spend more than 60 percent of their day hunting small fish to stay warm in the cold waters. New research shows that harbor porpoises spend little energy on this hunting strategy, but that it makes them vulnerable to human disturbance.
