For millions of years, giant sharks called megalodons were the ocean’s top predators. Then along came great white sharks. New analyses of shark teeth hint that these two marine monsters… Read More »Great white sharks may be partly to blame for the end of megalodons
Previously, it has been impossible to capture the high-resolution images of nitrogenase, the only enzyme capable of reducing nitrogen into ammonia, during catalytic action. Now researchers report near-atomic-resolution snapshots of… Read More »Researchers take first-ever cryo-EM images of nitrogenase in action
Advancing the potential applications of photoplethysmography, an optical technique used to measure heart rate, in cardiovascular and mental health monitoring requires the analysis of complex nonlinear data from photoplethysmograms (PPGs).… Read More »Decoding ‘photoplethysmograms’ to broaden the scope of health monitoring technologies
Engineers designed an adhesive patch that produces ultrasound images of the body. The stamp-sized device sticks to skin and can provide continuous ultrasound imaging of internal organs for 48 hours.… Read More »Engineers develop stickers that can see inside the body
Researchers have designed a machine learning method that can predict the structure of new materials with five times the efficiency of the current standard, removing a key roadblock in developing… Read More »AI tackles the challenge of materials structure prediction
