A new type of radar can measure objects down to centimeters. The new technique uses a photonic system to generate much higher bandwidth signals, enabling radar that can detect smaller objects, and even monitor patient vital signs in hospitals.

There may be new hope for people with certain types of blindness, as an experimental sight-restoring device has been deemed safe for implantation. It still has to be tested on humans, though, and it will likely provide a rudimentary form of vision.
-
A new meta-study has concluded blood or saliva THC concentrations are not effective ways to measure cannabis-induced driving impairment. The findings indicate impairment tests should be developed instead of looking to develop a marijuana breathalyzer.

While there are now systems that allow cars to see obstacles which their drivers may not notice, such setups still can't detect hazards that aren't in direct line of sight. New tech, however, uses other vehicles and roadside cameras to do that job.

A study found pupils respond in the same way to the number of objects in one’s field of vision as they do to light. Experiments revealed pupils dilate in response to images with more dots, indicating sensing numbers is an innate perceptual mechanism.

New research systematically investigating the anticonvulsant effects of a number of rare compounds in cannabis is reporting cannabigerolic acid (CBGA), known as the “mother of all cannabinoids”, may be more effective at reducing seizures than CBD.
-
Results have been published from a clinical trial testing a hypertension therapy that combines low-doses of four different blood-pressure-reducing drugs. The results indicate the strategy is more effective than any single high blood pressure treatment.

How long is a person’s ability to safely drive impaired after consuming cannabis? A meta-analysis suggests intoxication spans anywhere from three to 10 hours, raising questions over some roadside tests detecting traces of THC days after consumption.

By studying the twinkling of stars, astronomers in Australia have discovered a huge cloud of cold gas in our galaxy, not far from Earth. This invisible mass could provide new hints about where to find the universe’s missing matter.
-
A study into the effects of cannabis on driving in a real-world context has found CBD alone does not impair driving ability. The landmark finding promises to be invaluable in guiding road safety regulations as cannabis laws shift across the globe.
-
Scientists in Australia have happened upon a solution to one of the key instability issues facing perovskite solar technology, finding that doses of high-intensity light can be used to avoid deformations that plague the performance of the cell.
-
Scientists in Australia have turned their attention to what human development means for the world’s marine environments, calculating the extent of our construction footprint on the oceans for the first time ever.
