Researchers have developed the first LiDAR-based augmented reality head-up display for use in vehicles. Tests on a prototype version of the technology suggest that it could improve road safety by ‘seeing through’ objects to alert of potential hazards without distracting the driver.

The technology, developed by researchers from the University of Cambridge, the University of Oxford and University College London (UCL), is based on LiDAR (light detection and ranging), and uses LiDAR data to create ultra high-definition holographic representations of road objects which are beamed directly to the driver’s eyes, instead of 2D windscreen projections used in most head-up displays.

While the technology has not yet been test...

A new study led by a planetary scientist uses a computer model of Mars to put forth a promising explanation onto how Mars once contained rivers and lakes: Mars could have had a thin layer of icy, high-altitude clouds that caused a greenhouse effect.

One of the great mysteries of modern space science is neatly summed up by the view from NASA’s Perseverance, which just landed on Mars: Today it’s a desert planet, and yet the rover is sitting right next to an ancient river delta.

The apparent contradiction has puzzled scientists for decades, especially because at the same time that Mars had flowing rivers, it was getting less than a third as much sunshine as we ...

A study in cells and mice finds compound works with fewer side effects than opioids. Fentanyl, oxycodone, morphine—these substances are familiar to many as a source of both pain relief and the cause of a painful epidemic of addiction and death.

Scientists have attempted for years to balance the potent pain-relieving properties of opioids with their numerous negative side effects—with mostly mixed results.

Work by John Traynor, Ph.D., and Andrew Alt, Ph.D., and their team at the University of Michigan Edward F. Domino Research Center, funded by the National Institute on Drug Abuse, seeks to side-step these problems by harnessing the body’s own ability to block pain.

All opioid drugs—from poppy-derived opium to heroin—work on receptors that are naturally prese...

Known as ‘pair-density waves,’ it may be key to understanding how superconductivity can exist at relatively high temperatures...
