Common Pesticide Damages Honey Bee’s Ability to Fly

Biologists at UC San Diego have provided the first evidence that a widely used pesticide can significantly impair the ability of otherwise healthy honey bees to fly. The study, which employed a bee “flight mill,” raises concerns about how pesticides affect honey bee pollination and long-term effects on the health of honey bee colonies.

No Biochar Benefit for Temperate Zone Crops, Says New Report

Scientists believe that biochar, the partially burned remains of plants, has been used as fertilizer for at least 2,000 years in the Amazon Basin. Since initial studies published several years ago promoted biochar, farmers around the world have been using it as a soil additive to increase fertility and crop yields. But a new study casts doubt on biochar’s efficacy, finding that using it only improves crop growth in the tropics, with no yield benefit at all in the temperate zone.

Naked Mole-Rats Turn Into Plants When Oxygen Is Low

Deprived of oxygen, naked mole-rats can survive by metabolizing fructose just as plants do, researchers report this week in the journal Science – a finding that could lead to treatments for heart attacks and strokes.

Plant Scientists Identify Aphid-Destroying Wasps in Cup Plants

A photo of a cup plant teaming with insects led a better understanding of the biology of Acanthocaudus wasps which inject their eggs into aphids that eat the plant. The adult wasps burst out of the aphids like an alien movie.

New Method Can Model Chemistry in Extreme Magnetic Fields of White Dwarfs

Approximately 10-20 percent of white dwarfs exhibit strong magnetic fields, some of which can reach up to 100,000 tesla. In comparison, on Earth, the strongest magnetic fields that can be generated using nondestructive magnets are about 100 tesla. Therefore, studying the chemistry in such extreme conditions is only possible using theory and until now has not provided much insight to the spectra accompanying white dwarfs. Researchers in Germany describe their work modeling these systems this week in The Journal of Chemical Physics.
