Key Highlights
•
Researchers discovered that a protein called mitochondrial fission factor (MFF) controls hunger signals in the brain. When MFF is missing in specific neurons, it boosts the cells’ ability to take in calcium, making them more excitable and increasing food intake during times of energy need, offering a potential new target for treating metabolic disorders.

By recording brain activity directly from humans, scientists uncovered a “communication subspace” that efficiently channels decision-making information from the front of the brain to the motor cortex. This finding reveals how the brain coordinates complex, context-dependent movements, with important implications for understanding conditions like apraxia.

A study on wild Soay sheep shows that higher levels of the hormone IGF-1 in young lambs predict faster growth, larger body size, and a greater chance of surviving the first winter and reproducing. This work uncovers a key biological link between nutrition, growth, and survival in natural environments.

A major global analysis of 180 field trials found that adjusting soil pH can boost carbon storage by up to 20%. The process works by directing carbon into mineral-stabilized and physically protected pools, which suggests that managing soil pH could be a powerful strategy for creating long-term carbon sinks and combating climate change.
