Key players in brain aging: New research identifies age-related damage on a cellular level
Scientists have identified the molecular changes that occur in the brains of aging mice and located a hot spot where much of that damage is centralized. The cells in the area are also connected with metabolism, suggesting a connection between diet and brain health.

Revolutionizing heat management with high-performance cerium oxide thermal switches
Groundbreaking cerium oxide-based thermal switches achieve remarkable performance, transforming heat flow control with sustainable and efficient technology.
Researchers have come up with a new way to identify more infectious variants of viruses or bacteria that start spreading in humans -- including those causing flu, COVID, whooping cough and tuberculosis.
A tour de force: Engineers discover new 'all-optical' nanoscale sensors of force
Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' nanosensors are probed with light only and therefore allow for fully remote read-outs -- no wires or connections are needed.
Ancient DNA unlocks new understanding of migrations in the first millennium AD
Waves of human migration across Europe during the first millennium AD have been revealed using a more precise method of analysing ancestry with ancient DNA, in research led by the Francis Crick Institute.
Scientists pin down the origins of a fast radio burst
Astronomers pinned down the origins of at least one fast radio burst, a brief and brilliant explosion of radio waves emitted by an extremely compact object. The team's novel technique might also reveal the sources of other FRBs.
Achieving bone regeneration and adhesion with harmless visible light
A team develops an innovative injectable hydrogel for bone regeneration, addressing the limitations of traditional bone grafts and adhesion methods.
A groundbreaking study has shed light on the complex interactions between dystrophin, a protein critical to muscle stability, and its partner protein, dystrobrevin, offering new pathways for understanding and treating Duchenne Muscular Dystrophy (DMD).
