Brain Taps Lipid Stores for Energy During Activity

Contrary to long-held assumptions, neurons can break down fat for energy when glucose is in short supply.

In a new study, researchers found that lipid droplets inside neurons are activated by synaptic electrical activity and metabolized into fatty acids that fuel mitochondria.

This fat-burning process is controlled by the brain's activity level—more active neurons burn more fat.

Disrupting the pathway that transports fatty acids into mitochondria led to a torpor-like state in mice, highlighting its biological importance.

The findings challenge the view that fat metabolism is irrelevant to brain function.

They also suggest new avenues for understanding neurodegenerative diseases that involve disrupted energy metabolism. Brain Taps Lipid Stores for Energy During Activity

Aging Spreads Through the Bloodstream

Aging may spread through the body like a signal, and a new study pinpoints ReHMGB1 as the messenger.

Released by senescent cells, this molecule circulates in the blood and triggers aging in distant tissues such as muscle, kidney, and skin.

The researchers found that ReHMGB1—but not its oxidized form—activates key pathways associated with cell damage and inflammation.

Treating mice with antibodies against HMGB1 not only reduced signs of aging in cells but also improved muscle regeneration.

These results suggest that aging is a transmissible cellular state, not just the sum of isolated declines.

Blocking this signal may help protect tissues from age-related degeneration. Aging Spreads Through the Bloodstream

Aging isn’t isolated—it spreads through the blood. Scientists found ReHMGB1 drives body-wide senescence, but blocking it restores regeneration. A promising new target in the fight against aging.

When Sight Meets Sound: How the Brain Binds Audiovisual Memories

The brain forms rich, multisensory memories by binding together sights and sounds, like recalling a friend’s face and voice telling a joke.

A new study explored how this audiovisual integration works by showing participants movie clips of people speaking, with either synchronized or desynchronized lip movements and speech sounds.

Synchronized clips triggered specific oscillatory activity in two brain regions during viewing.

This same brain activity resurfaced when participants later recalled the clips, suggesting a strong link to memory formation.

In contrast, clips with delayed speech sounds weakened both the initial brain activity and later memory recall.

These findings imply that when visual and auditory signals arrive at the brain simultaneously, they align within the same neural rhythm, increasing the likelihood of being stored as a unified memory. When Sight Meets Sound: How the Brain Binds Audiovisual Memories

New research shows that synchrony between sight and sound boosts how we form memories. When lip movements and speech are perfectly timed, our brains lock into rhythmic activity that helps encode and recall audiovisual moments. Timing, it turns out, is everything.
