Melting and breaking icebergs in the far-off Pacific Ocean can weaken a massive current system in the Atlantic Ocean, a UC Davis study finds.

Researchers have designed and built the first 3D device that can make objects invisible to heat, an advance that could transform how we protect sensitive electronics, manage heat in microchips and shield equipment from thermal detection.

Drought is a persistent issue in agriculture, so Colorado State University continually works to identify and develop drought-tolerance traits in crops to ensure farmers can remain competitive and provide food for people and livestock.

By designing computers to behave more like the brain, engineers seek faster, more energy-efficient computing. Most researchers attempt to mimic the cerebrum, which underlies reasoning, memory and language. New device is first to mimic the cerebellum, the brain’s reflex center. Device identified abnormal heartbeats from ECGs within one-fifth of a heartbeat, 98% accuracy and 10,000 times fewer computer operations.

Through experiments comparing living representatives of animal groups that dominated Paleozoic oceans with those that thrive today, Stanford scientists have directly linked the disappearance of once-dominant marine groups to intolerable heat and diminished oxygen in ancient oceans.

By the time farmers see curling leaves or stunted growth in their fields, their crops may already have spent days under stress. A new innovation in plant “wearable” sensors aims to catch those distress signals earlier—before the plant visibly suffers, allowing farmers to respond and help their crops thrive.

Newly developed microparticles can infiltrate stubborn bacterial matrices and release tiny oxygen bubbles to clean surfaces and wounds more efficiently than hydrogen peroxide or other cleaning agents alone, researchers at the University of Illinois Urbana-Champaign report. In two papers they demonstrated the bubble-generating particles’ ability to clean tenacious biofilms from surgical instruments and, when embedded within bandages, to clean infected wounds and speed healing.
