The acidity of drinks like Red Bull can erode dental enamel, but a lab experiment suggests this could be avoided via calcium fortification

Stanford researchers discovered that dialing down an overactive enzyme, LRRK2, can regrow lost cellular “antennae” in key brain cells, restoring vital dopamine communication and neuroprotective signals in a mouse model of genetic Parkinson’s. After three months on the LRRK2-blocking drug MLi-2, damaged circuits revived and early signs of neuronal recovery emerged, hinting that timely treatment could not only halt but reverse disease progression—and perhaps benefit other Parkinson’s forms.

Tropical trees are dying faster than ever, and it’s not just heat or drought to blame. Scientists have uncovered a surprising culprit: ordinary thunderstorms. These quick, fierce storms, powered by climate change, are toppling trees with intense winds and lightning, sometimes causing more damage than drought itself. The discovery is reshaping how we understand rainforest health and carbon storage, as storms may be responsible for up to 60% of tree deaths in some regions. Researchers now warn that failing to account for this hidden force could undermine forest conservation and climate models alike.
