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 ...
Neural crest cells are a population of stem cells that invade the embryo in early development. They play a big role in what you look like: the pigments of your eyes, of your skin, and the bone structure of your face are all ...
A great white shark is a masterwork of evolutionary engineering. These beautiful predators glide effortlessly through the water, each slow, deliberate sweep of the powerful tail driving a body specialized for stealth, speed ...
Scientists analyzing 443-million-year-old Scottish fossils have uncovered the early evidence that some of the first groups of vertebrates possessed surprisingly advanced eyes and traces of bone, reshaping our understanding ...
One llama is sprawled on the grass with its neck craned, basking in a patch of sunshine. Another stands on a dirt hill, ears flattened defiantly. A third rushes to greet visitors with a friendly nuzzle. This isn't a petting ...
