Stanford scientists have discovered a new type of immune cell that kills surrounding cells via explosion—a cellular detonation so fast and complete that the cell vanishes within minutes, leaving no trace behind. This discovery ...
When doctors and scientists want to see inside a body, magnetic resonance imaging (MRI) is a powerful tool. MRI can noninvasively capture detailed images of the body's muscles, organs, and bones. It can monitor blood flow ...
When nuclear accidents happen, many people imagine radiation spreading everywhere and lasting forever. The reality is more complex. Radioactive materials move, change and sometimes disappear faster than people expect.
New research by an interdisciplinary team in Lithuania has revealed a promising and unconventional approach to cartilage regeneration. Using extracellular vesicles derived from menstrual blood stromal cells, the researchers ...
Experiments conducted in Brazil using laboratory rats have shown that graphene-based structures can act as a powerful ally in bone regeneration. These structures are made of sheets of the chemical element carbon that are ...
The Nanomedicine and Nanotoxicology Group (GNano) at the University of São Paulo's São Carlos Institute of Physics (IFSC-USP) in Brazil has discovered a way to transform hydroxyapatite, a bioceramic material, into a nanoparticle ...
Researchers at the University of Michigan have discovered that the constant gnawing of rodents isn't just a reflex or a consequence of a tough diet. It also triggers a release of dopamine in the brain—which acts as a biochemical ...
Bones broken in a skiing accident usually heal on their own. But if the break is too severe or a bone tumor needs to be removed, surgeons insert an implant that enables the bone to grow back together. Implants often consist ...
Scores of sea lions continue to beach themselves along the Southern California coastline, stricken with sickness. Toxic algae blooms are to blame, though a mechanical engineering innovation could shift the tide in favor of ...
In a 2023 paper on hypoxia and glucose metabolism, our lab showed how organisms rewire their metabolism to adapt to low oxygen levels—such as those found at high altitudes. One of the most striking observations from that ...
