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.

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.

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.
