As of now, 18 states have legalized recreational marijuana use while 36 have 'medical' cannabis laws but there is still debate about how cannabis may affect the abilities, real and perceived, of drivers under the influence.

A two-year randomized trial, conducted at the Center for Medicinal Cannabis Research (CMCR) at University of California San Diego School of Medicine hopes to add some science to the anecdotes. Researchers recruited 191 regular cannabis users to partake of cannabis containing different levels of delta-9-tetrahydrocannabinol (THC), the psychoactive compound in cannabis or a placebo immediately before a series of driving simulation tests over several hours.

Long before there were Israelites, Sumerians, or Egyptians in the world, the people living in Israel experienced a boom in food quantity and diversity, and a new study finds that the reason was climate change 23,000 years ago.

Ohalo II is a submerged archaeological site on the southern tip of the Sea of Galilee in Israel and in it are preserved extensive evidence of human occupation about 23,000 years ago. Climate change was a given, the world was exiting its latest periodic ice age. Humans diversified their dietary habits. Some have posited that the changes in food were due to decreasing food availability, while others suggest the change was thanks to increasing food abundance.

A lot of media articles a decade ago worried about risk to honeybees from crop protection products while science should have been worried more about the viruses they carry that put plants at risk of disease.

A recent study sequenced the genetic material present on the pollen grains of 24 plant species across the U.S., the group found signs of many of the plant viruses already shown to travel on pollen—along with six new species, three new variants of known species and the incomplete traces of more than 200 more that have never before been identified.

In a pilot study, a fat injection procedure improved symptoms of plantar fasciitis in patients, and the authors of the paper hope it will get a company or NGO interested in a clinical trial. 

All coronaviruses, and certainly SARS-CoV-2, have become famous as a respiratory virus, but acute COVID-19 infection has been linked to many different organ systems, including the brain, resulting in a wide range of neurological complications with long-lasting impacts.

 According to a new paper by Serena Spudich and Avindra Nath, cases of neurological “Long Covid” symptoms may result from the emergence and persistence of these mechanisms and the neurological symptoms that accompany COVID-19.

A new study finds that oral stimuli during the chewing of food can help increase energy expenditure of body and prevent obesity.

Chew your food well is ancient wisdom.  In the past, the belief was perhaps because there was less food anyway. Chewing it longer gave the brain and stomach time to catch up with each other. Many people have reported 'their eyes are bigger than their stomach' and feeling hungry until they were very full. Others said it made digestion easier.
