Scientists studying the behavior of wild octopuses off the coast of Australia have made a strange discovery, with the creatures caught hurling silt, algae and even shells at one another in a rare example of animal throwing behavior.

Processed foods have never been favorites of nutritionists, and recent research now bolsters the claim that such foods are the leading cause of obesity in the Western world. It all comes down to something known as the Protein Leverage Hypothesis.

Scientists are claiming an advance in regenerative medicine through the development of a novel material that mimics the structure of living blood vessels, which sees it grow with the body after transplantation.

Astronomers have discovered a strange neutron star that challenges our understanding of them – but may help unlock the mystery of fast radio bursts. The object spins far slower than any known neutron star, and gives off seven types of radio pulses.

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.
