ALT 🧠 Your brain may be switching between two versions of reality 15 times every second What if your brain is processing two different versions of what you see, but you are only aware of one? A fascinating new study suggests that the brain may rapidly switch between visual information that reaches our conscious awareness and information that remains hidden from us. And this may happen around **15 times every second!** In experiments, researchers showed monkeys two different faces, one to each eye. Although one face dominated what they appeared to perceive, brain activity continued to alternate between signals linked to both faces. The surprising part? **Even when your brain focuses on one thing, information you are not consciously aware of may still be active behind the scenes.** Scientists believe this could help explain how the brain separates conscious experience from the enormous amount of information it receives every moment.

ALT ☢️ The Black Fungus That May Use Radiation to Its Advantage Deep inside the radioactive ruins of Chernobyl, scientists discovered something extraordinary. Certain dark fungi can survive in environments where radiation levels are dangerously high. One species, Cladosporium sphaerospermum, contains melanin, the same type of pigment that gives human skin its color. In fungi, this pigment may help protect cells against environmental stress, including radiation damage. But the mystery goes deeper. Laboratory experiments suggest that ionizing radiation can change the biological activity of some melanized fungi. Scientists are investigating whether melanin helps them capture energy from radiation, a proposed process called radiosynthesis. However, researchers have not established that these fungi use radiation as a direct energy source in the same way plants use sunlight. Their ability to survive extreme conditions is fascinating, but the exact mechanisms are still being studied.

ALT 🧠 Scientists Replaced More Than 85% of Brain Immune Cells in Mice, Offering New Hope for Brain Diseases. What if damaged brain cells could be replaced by healthy ones? Scientists at Stanford Medicine are exploring a remarkable approach involving microglia, the brain’s immune cells that help clear waste and protect nerve cells. 🔬 In experiments involving mice with a fatal genetic brain disease, researchers introduced healthy precursor cells that developed into microglia. These cells helped deliver missing enzymes to neighboring brain cells, reduced brain damage, and improved movement and survival. The results are promising, but there is an important catch: this treatment remains experimental. It has not been proven to cure these diseases in humans. Could replacing the brain’s own immune cells become a future treatment for devastating neurological disorders? Scientists are working to find out.
