New research has revealed significant changes to Alaska’s landscape in recent decades.

For decades, astronomers have puzzled over the exact source of a peculiar type of faint microwave light emanating from a number of regions across the Milky Way. Known as anomalous microwave emission (AME), this light comes from energy released by rapidly spinning nanoparticles – bits of matter so small that they defy detection by ordinary microscopes. (The period on an average printed page is approximately 500,000 nanometers across.)

The second major hurricane of the Eastern Pacific Ocean season formed after the first hurricane, Aletta, weakened. NOAA's GOES-West satellite captured an image of Hurricane Bud on June 11.

Measurements as well as model calculations equally show that the oxygen inventory of the oceans is decreasing. However, the models underestimate this decrease significantly making projections into the future problematic. In a study published today in the international journal Nature Geoscience, four GEOMAR researchers reveal the gaps in the models and identify further, previously underestimated drivers for the deoxygenation.

Researchers at Western University have shown that our brains are pre-wired to perceive wrinkles around the eyes as conveying more intense and more sincere emotions. This eye-wrinkle feature, called the Duchenne marker, occurs across multiple facial expressions, including smiles, expressions associated with pain, and­—as found by these researchers—expressions of sadness.
