Many of the plants inhabiting northern mountains depend on the snow cover lingering until late spring or summer. Snow provides shelter for plants from winter-time extreme events but at the same time it shortens the length of growing season, which prevents the establishment of more southern plants. This is why the reduced snow cover may be an even larger threat to the Arctic plants than rising temperatures.

Researchers have better unraveled the complex process of how black widow spiders transform proteins into steel-strength fibers. This knowledge promises to aid scientists in creating equally strong synthetic materials. Utilizing state-of-the-art techniques, the research team was able to more closely see inside the protein gland where the silk fibers originate, revealing a more complex, hierarchical protein assembly. The researchers' 'modified micelles theory' concludes that spider silk proteins start out as complex, compound micelles.

NASA's MarCO mission was designed to find out if briefcase-sized spacecraft called CubeSats could survive the journey to deep space. Now, MarCO -- which stands for Mars Cube One -- has Mars in sight.
