July was the planet"s hottest month on record—so far
A sizzling month marked by record heat waves, major wildfires, melting sea ice and a burgeoning El Niño will go down in the books as the hottest July on record—at least until next year, federal officials said Monday......»»
Researchers take important step toward developing cavity-based X-ray laser technology
Researchers have announced an important step in the development of a next-gen technology for making X-ray free-electron laser pulses brighter and more stable. They used precisely aligned mirrors made of high-quality synthetic diamond to steer X-ray l.....»»
What"s in the mysterious waters of Tulare Lake? Contaminants, egrets and many unknowns
Out on the water, a silence hangs in the air and the sun's harsh glare reflects off the lake's still surface. Small fish float belly-up alongside snakelike tubes of irrigation piping. Five feet below, abandoned chicken coops, dairy barns and equipmen.....»»
Could artificially dimming the sun prevent ice melt?
With methods of so-called geoengineering, the climate could theoretically be artificially influenced and cooled. Bernese researchers have now investigated whether it would be possible to prevent the melting of the West Antarctic ice sheet by artifici.....»»
Femtosecond laser technique births "dancing microrobots": A breakthrough in multi-material microfabrication
A research team led by Prof. Wu Dong from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a femtosecond laser 2-in-1 writing multi-material processing strategy to fabricate micromachined join.....»»
Zentropy and the art of creating new ferroelectric materials
Systems in the universe trend toward disorder, with only applied energy keeping the chaos at bay. The concept is called entropy, and examples can be found everywhere: ice melting, campfire burning, water boiling. Zentropy theory, however, adds anothe.....»»
