Old dogs are helping scientists combat human aging
By studying donated tissues stored in a pet dog biobank, researchers have uncovered a genetic link between brain aging in canines and humans.
Supercentenarians’ DNA reveals clues to human longevity
A human longevity study involving people over the age of 105 has found that genetic variants linked to DNA repair appear to contribute to a longer life.
"Octopus vision" may help prevent human blindness
A new medical device that gives optometrists a fast, easy way to monitor a key macular degeneration risk factor was inspired by octopus vision.
New blood test could predict the onset of labor
Stanford University researchers have identified blood-based biomarkers that can be used to predict the onset of labor in pregnant women.
Customized stem cells could show us how dementia happens
By turning human cells into induced pluripotent stem cells, researchers hope to finally map the genetic path to Alzheimer’s disease.
Scientists may have figured out how to fight prion disease
Researchers believe they have found a spot on a mutated prion protein that can lead to brain-spongifying disease.
Bacteria nanomachines fire smart missiles that could replace antibiotics
Researchers want to use bacteria-made nanomachines called tailocins to help fight enemy bacteria strains in the human body.
Nobel prize-winning chemist helps invent synthetic mucus
Mucins, the long proteins in mucus, have an array of bacteria-fighting properties. These artificial mucins can act like the real thing.
The next generation of living machines: xenobots 2.0
Made from the stem cells of a frog, “Xenobots” are tiny living machines. And researchers have just debuted version 2.0.
