The study looked at the effect of cannabis use on young adults who are recent or heavy users
AURORA, Colo., Jan. 28, 2025 /PRNewswire/ — A new study published today in JAMA Network Open explores the effects of both recent and lifetime cannabis use on brain function during cognitive tasks.
The study, the largest of its kind ever to be completed, examined the effects of cannabis use on over 1,000 young adults aged 22 to 36 using brain imaging technology. The researchers found that 63% of heavy lifetime cannabis users exhibited reduced brain activity during a working memory task, while 68% of recent users also demonstrated a similar impact.
Dario Amodei argues we must limit China’s access to AI chips so we can live under all powerful American-owned AI as opposed to all powerful Chinese-owned AI.
What if time didn’t just move forward? Scientists have uncovered something astonishing in a recent quantum physics experiment — the existence of ‘negative time.’ This mind-bending discovery defies conventional logic, suggesting that particles may not follow the rules we thought were unbreakable.
We often see stories of invincible warriors with superhuman abilities combating monstrous threats, but are the days of super soldiers nearly upon us, and could they be the biggest threat of all?

Now scientists believe they have made a breakthrough by creating implantable patches composed of beating heart muscle that can help the organ contract.
Prof Ingo Kutschka, the co-author of the work from University Medical Center Göttingen in Germany, said: “We now have, for the first time, a laboratory grown biological transplant available, which has the potential to stabilise and strengthen the heart muscle.”
The patches are made from cells taken from blood and “reprogrammed” to act as stem cells, which can develop into any cell type in the body.
