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.

An international team of scientists has created a new type of solar flow battery that’s efficient and long-lasting. The device is made up of a silicon/perovskite tandem solar cell, paired with a redox flow battery, with organic chemical electrolytes.

Making biofuel from algae is showing promise as a green energy source, but it does create large amounts of toxic wastewater. Now, researchers in Australia have found a way to clean up that wastewater, with a simple and scalable electrical process.

Scientists in Australia have delved into the dining habits of juvenile great white sharks and discovered a humble diet that belies their image as a fearsome predator, with bottom-dwelling creatures making up a decent portion of their meals.

Not only do ticks suck your blood, but they're able to do so for a long time, undetected. Scientists have now synthesized the protein that lets them get away with it, and it may have life-saving medical applications.

Scientists investigating the genetics underlying a peculiar behavior in South Africa’s Cape honey bee have made a groundbreaking discovery, pinpointing the single gene that enables them to reproduce without having sex.

Rupturing tendons or ligaments like an anterior cruciate ligament in the knees can mean long stints on the sidelines, but a new type of synthetic material promises to help things along by acting as a scaffold to accelerate the regeneration of tissue.

Researchers have discovered how intermittent fasting influences metabolic pathways in the liver, offering insights into how fasting can confer certain health benefits and hypothesizing specific drugs could mimic these effects without needing to fast.
