Brain scans reveal a possible cause of long COVID fatigue and brain fog
Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that target the brain's dopamine system.

Stem cells reverse stroke damage and restore movement in mice
Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help repair the human brain after stroke.

Stopping Ozempic may raise heart attack and stroke risk
A large study suggests the cardiovascular benefits of GLP-1 drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound can disappear surprisingly quickly when treatment stops. After two years off the medications, patients had a 22% higher risk of heart attack, stroke, and death compared with those who stayed on them.

Black holes of every size follow the same surprising rule
Scientists have found evidence that black holes of vastly different sizes may launch powerful jets according to the same universal rule. Supermassive black holes can produce jets soon after tearing apart a star, then fire up again hundreds or thousands of days later when their feeding rate drops to about 2% of the Eddington limit. That same threshold is known to trigger jets from much smaller black holes in the Milky Way.

A new process turns plastic waste into gasoline and diesel fuel
Scientists at Oak Ridge National Laboratory have developed a surprisingly simple way to turn polyethylene, the common plastic used in shopping bags and cutting boards, into gasoline and diesel-like fuels. The process uses inexpensive aluminum-based molten salts to break long plastic molecules into smaller hydrocarbons, producing about 60% gasoline under relatively mild conditions.
