Most of us try to keep our teeth clean and nice-looking. But we don’t spend a lot of time thinking about what’s inside our teeth until something bad happens. When dental problems arise, in some cases the only way to…
Genetic variants linked to DNA repair appear to contribute to a longer life. By studying the genomes of people over the age of 105, an international team of researchers has identified several genetic factors that appear linked to human longevity — and…
PORTLAND, Maine (AP) — Sharks use the Earth’s magnetic field as a sort of natural GPS to navigate journeys that take them great distances across the world’s oceans, scientists have found. Researchers said their marine laboratory experiments with a small…
Fossil apes can inform us about essential aspects of ape and human evolution, including the nature of our last common ancestor AMERICAN MUSEUM OF NATURAL HISTORY In the 150 years since Charles Darwin speculated that humans originated in Africa, the…
Largest study of its kind reveals the way relative brain size of mammals changed over the last 150 million years The idea that comparing brain size to body size for any species provides a measure of the species’ intelligence is…
The attention-grabbing study found smokers were 23% less likely to catch COVID-19, and now it’s been retracted by the journal that published it. Medical research has always been a crucial component of public health, and the COVID-19 pandemic has made…
These nanorobot-like microorganisms are viruses called bacteriophages as they only infect and lyse bacteria. Bacteriophages were discovered in 1915 by Frederick Twort in England, and by Félix d’Herelle in 1917 in France who first applied the discovery to human healthcare to…
Finding out what makes a prion protein go bad may help control these brain-eating pathogens. Prions are believed to be the cause of an array of rare but horrifying neurological diseases, such as Variant Creutzfeldt-Jakob disease (known, in cattle, as…
Anewfound feature of human anatomy made up of a series of compartments is interconnected throughout the body, researchers at NYU Grossman School of Medicine have discovered. This anatomical “highway” provides a route for normal signals and may potentially be involved…
Understanding these tiny organisms could be crucial to tackling threats such as coronavirus, but new research shows how little we know A new study has highlighted how little is known about microbes – the hidden majority of life on Earth.…
