It isn’t easy to diagnose wound infections before they’ve progressed into a nasty, purulent mess, and many doctors prefer to play it safe by doling out antibiotics early. But a clever new bandage that glows bright green at its first whiff of bad bacteria could help change that.
Did an asteroid hasten the spread of black death in Europe? Dendrochronologist and author Mike Baillie says that tree rings "reveal a major event just before 1350. Something catastrophic," similar to the Tunguska event, changed "the composition of the atmosphere and provided ideal conditions for a lethal infection to…
Globally, we have Polio on the ropes. It's been eradicated in countless countries across the globe. It should only be a matter of time before it goes the way of Smallpox. But there are a few hold-outs, where the virus is stubbornly hanging on. This story is about a virus's last ditch effort to survive.
U.S. scientists studying throat microbes have inadvertently stumbled upon an algae virus that appears to have a slight but measurable detrimental affect on cognitive functioning in humans, including visual processing and spatial orientation. Disturbingly, millions of us could already be infected.
The fact that humans and animals suffer from many of the same diseases is no longer controversial. But do they have similar causes? How do factors like air quality, social stress, and the built environment contribute to health and illness in people and animals?
Remember that time your skin got all gnarly and you went to the doctor and she told you you'd been bitten by a brown recluse? Chances are you actually had a case of MRSA. Which... oh good, hooray?
Redditor johnboy9210 retrieved a football from a stagnant koi pond one day and contracted necrotizing fasciitis, the infamous flesh-eating disease. Fortunately, we don't have to experience the tissue-chomping bacteria first-hand, and can instead witness his photographic account from the early signs of infection…
This is terrifying and sad all at the same time. Scientists have known about Chrysosporium for years, but they've never known it to do this. The ghastly fungal infection — notorious for popping up in captive animals around the world — has made the leap to a population of endangered rattlesnakes in Illinois, posing a…
Three million years ago, a gene mutation switched off a sugar-making enzyme in early hominids. Our ancestors actually became unable to breed with those who still had the enzyme, possibly causing the emergence of our evolutionary grandparent, Homo erectus.
The single-celled parasite Toxoplasma gondii lives infects rats, but it needs to be inside a cat's digestive system in order to reproduce. The parasite actually alters the brain of its rat host so that it won't be afraid of cats.
Sooty mangabeys are a monkey species found on the western coast of central Africa. Their unique immunity to SIV, a relative of HIV, has intrigued medical researchers for decades. Now we know just how their immunity works.
Doctors may be able to kill off persistent staph infections using a cheap and easy method. A little boost of sugar can help kill the type of bacteria that regular antibiotics miss.
The visible concentric circles you see in this picture show a bacteria swarm as the colony starts and stops its progress. Now Spanish researchers have discovered a key component of infectious bacteria's battle plan - and how to stop it.
Although some kinds of nanomaterials (like carbon nanotubes) can be harmful to your health, scientists are quickly developing nanoparticle therapies that can fight cancer and bacterial infections better than any of our current medications.
You've probably heard that all the antibiotics we take are breeding new generations of drug-resistant bacteria. In fact, many diseases we once killed easily with Penicillin now require mega-doses of super-antibiotics like Cipro. While researchers have known for a long time that bacteria are developing resistance to…
Your next kiss could turn into an infection that eats your lips off. San Francisco and Boston are reporting outbreaks of drug-resistant staph bacteria that cannot be stopped with any antibiotics currently being used to fight them. When the bacteria come into contact with your skin, they can burrow into tiny cuts and…
