In this image, engineered hydrogel is being pulled away from a glass surface. Engineers at MIT have developed a method to make synthetic, sticky hydrogel that is more than 90 percent water. The material shows a property called “tough wet adhesion” comparable to tendon and bone interface. The wavy edge instability at the interface is a hallmark of strongly adhered soft material on a ri...
A peek at the secret life of pandas News.science360.gov.org

The origin of the contrails was an Etihad Airbus A380 (as identified by Meteosuisse -- the Swiss governmental meteorologic board). This aircraft had cruised by at approximately 40,000 ft (12,190 m),...

Hexagonal ice crystals composing the cirrus overcast generated several splendid arcs and circles, some that were quite colorful. I was especially excited to see a nearly complete parhelic circle. This colorless band appears...

About 13 billion years ago, long before our sun formed, the construction of our Milky Way galaxy was just beginning. Young, mostly sun-like stars in the core, or central bulge, provided the building blocks for the galaxy's foundation. Many of these building-block stars have long since burned out, and are now just dying embers. But contained within these dead ...
