<div style="font-family:Helvetica, sans-serif; text-align:left;color:#999;font-size:11px;font-weight:bold;line-height:15px;">Jul 5th 2025, 09:10</div>
<div style="font-family:Helvetica, sans-serif; color:#494949;text-align:justify;font-size:13px;">
<p>In the frozen reaches of the planet—glaciers, mountaintops, and icy groundwater—scientists have uncovered strange light-sensitive molecules in tiny microbes. These “cryorhodopsins” can respond to light in ways that might let researchers turn brain cells on and off like switches. Some even glow blue, a rare and useful trait for medical applications. These molecules may help the microbes sense dangerous UV light in extreme environments, and scientists believe they could one day power new brain tech, like light-based hearing aids or next-level neuroscience tools—all thanks to proteins that thrive in the cold and shimmer under light.</p>

<p>Mice taught to link smells with tastes, and later fear, revealed how the amygdala teams up with cortical regions to let the brain draw powerful indirect connections. Disabling this circuit erased the links, hinting that similar pathways in humans could underlie disorders like PTSD and psychosis, and might be tuned with future brain-modulation therapies.</p>

<p>Smarter people don’t just crunch numbers better—they actually see the future more clearly. Examining thousands of over-50s, Bath researchers found the brightest minds made life-expectancy forecasts more than twice as accurate as those with the lowest IQs. By tying cognitive tests and genetic markers to real-world predictions, the study shows how sharp probability skills translate into wiser decisions about everything from crossing the road to planning retirement—and hints that clearer risk information could help everyone close the gap.</p>

<p>Researchers from Sweden have discovered that the human brain continues to grow new cells in the memory region—called the hippocampus—even into old age. Using advanced tools to examine brain samples from people of all ages, the team identified the early-stage cells that eventually become neurons. These findings confirm that our brains remain more adaptable than previously believed, opening the door to potential treatments for memory loss and brain-related disorders.</p>
