Twistoptics--A new way to control optical nonlinearity

Researchers at Columbia University School of Engineering and Applied Science have developed a new technique to control optical nonlinearity in 2D materials. The twistoptics approach enables giant nonlinear optical responses in small volumes, leading to compact laser systems and potential applications in quantum computing, spectroscopy,...

Assessing patients' kidney health may help predict their risk of cardiovascular disease

Measures of kidney function, such as the urinary albumin-to-creatinine ratio and estimated glomerular filtration rate, may improve estimates of future cardiovascular disease risk. The addition of these non-traditional risk factors could refine stratification and predict cardiovascular disease more accurately.

Prehistoric killing machine exposed

A new study reveals that the Anteosaurus, a 260-million-year-old predator, was capable of outrunning and tracking down its prey effectively due to its specialized nervous system and fine-tuned sensory organs. The research found that the animal's brain and balance organs were optimized for hunting swiftly and striking fast.
