Dirty snow may warm Arctic as much as greenhouse gases

...ical Research. Dirty snow has had a significant impact on climate warming since the Industrial Revolution. In the past 200 years, the Earth has warmed about .8 degree Celsius. Zender, graduate student Mark Flanner, and their colleagues calculated that dirty snow caused the Earth’s temperature to rise .1 ...

In mice, drug protects against diabetes and atherosclerosis

... percent compared to control mice. To study the impact of the aP2 inhibitor on diabetes, the scientists used a genetic animal model of obesity and insulin resistance, as well as normal mice fed a diabetes-inducing diet. In both animal models, the mice that received the inhibitor drug were found to hav...

New study finds genetically engineered crops could play a role in sustainable agriculture

... study analyzes, for the first time, environmental impact data from field experiments all over the world, involving corn and cotton plants with a Bt gene inserted for its insecticidal properties. The research was conducted by scientists at the National Center for Ecological Analysis and Synthesis (NCEAS) a...

Undergraduate research shows leaderless honeybee organizing

...se it shows that though the queen has a tremendous impact on the colony, she’s not the decision maker,” Schnieder said. “The colony is not a dominance hierarchy and, from a human perspective, this is unusual. Our human society is very dominance hierarchy structured --we have centralized systems of control....

Research finds that circadian rhythms dominate all life functions

...ikely reason why researchers previously missed the impact of circadian rhythm on all genes. Depending upon environmental factors, groups of genes can function in a synchronized manner, shifting in time against each other and working in what resembles a domino effect. However, very few genes are found t...
