Recent satellite data show no definitive warming trend in Earth's lower atmosphere over past two decades, contradicting computer models' predictions. The accurate temperature measurements are verified by multiple methods, including balloon-borne observations and intercalibration among orbiting platforms.
Researchers have discovered that common antibiotics like streptomycin can cause hearing loss and kidney damage in some individuals. Using iron chelators to prevent the formation of toxic molecules could provide a safe and inexpensive solution.
A Yale University robot is modeled after bat and dolphin echolocation behavior, exploiting sensor mobility and rotating ears to pinpoint objects. The robot can detect and identify various objects, such as coins and ball bearings, with high accuracy and ease.
A phase I multicenter trial uses transgenic pig livers as an ex vivo support system to remove toxins from patients' blood, extending their lives until a human donor liver is available. Researchers aim to alleviate the critical shortage of human donor organs, which claims 3,000 lives per year in the US.
