Inspired by nature, medical scientists have developed a flexible and biocompatible light-activated glue that works on wet tissue. And remarkably, it's as strong as traditional sutures.
While DNA is the building block of life, its cousin RNA keeps the show running smoothly, as it carries the information from DNA that allow genes to be expressed. RNA's ability to increase or decrease the expression of genes means it has huge potential to treat diseases at the genetic level, including tumors and…
Pandas aren't exactly renowned for their health and hardiness — if anything, they've earned a reputation as a fragile, sex-averse species that needs constant human conservation just to keep from going extinct. Well, they might be about to repay the favor in a big way, thanks to a powerful antibiotic locked inside…
The drug rapamycin comes from bacteria found in the soils of Easter Island. It's helped save lives for over a decade by preventing rejection in organ transplants, but that might just be scratching the surface of what it can do.
Swiss scientists have conducted an experiment in which paraplegic rats have re-learned to walk, run, and evade obstacles. The spectacular results followed a physical training regimen that included electrical and chemical stimulation of the rats' damaged spinal columns and the use of a "robotic postural interface".…
Some laboratory mice were given specially engineered insuling-producing genes. These genes were then remotely activated using radio waves. This could mean a whole new field of medical procedures in which we turn genes on and off at will.
Chocolate, like any other candy, makes you fat. That's such a basic and well-known fact that it's easily taken for granted... but it could be wrong. New research reveals that people who regularly eat chocolate are thinner than those who don't.
Because flu viruses mutate so fast, the only way to stop them is to destroy their ability to evolve. That's the key to creating a universal flu vaccine... and now we may have found the secret to creating one, and wiping out the flu.
Exactly how long we're supposed to sleep each night can vary depending on who you talk to, but we all seem to agree on one thing: you want to get one long, uninterrupted sleep. But it wasn't always that way.
In 1979, the World Health Organization successfully eradicated smallpox, removing one of history's greatest killers from the face of the Earth. Now, 33 years later, we just might be on the verge of repeating that feat with polio.
Some of the most deadly human diseases work by worming their way inside your DNA, attaching themselves to the cell's chromosomes. This makes them almost impossible to remove. But a new molecule designed to bamboozle rogue DNA could change everything.
The world's smallest ear doesn't belong to any animal. Instead, it's a tiny piece of gold suspended in a laser beam. It can hear sounds a million times fainter than any human ear can, making it a powerful acoustic microscope.
The appendix is probably the most famous of humanity's vestigial organs, but it might not actually deserve the "vestigial" part of that title. The appendix may actually save vital bacteria for the body's later use.
Scientists have long searched unsuccessfully for the genetic factors that cause schizophrenia. Now we know why: the disorder is actually caused by what happens in cells around the genes. That knowledge could give us our best treatment yet for schizophrenia.
Even though malaria deaths are down a very encouraging 25%, it remains one of the most devastating diseases in the world. Now we might have an unexpected new tool to fight against the spread of malaria: our natural smelliness.
Our most powerful antibiotics can kill many different kinds of bacterial infections at once, but we're still searching for a single all-purpose drug that kills viruses. We may have just discovered it.
Some of the most foul smelling creatures on Earth are known simply as odorous frogs. These amphibians have a normal odor like that of rotting fish, but it's worth braving their disgusting smell for the life-saving substances that coat their bodies.
We've known for a while now that moderate wine-drinking can confer some health benefits. Now a new study reveals moderate beer consumption can also reduce the risk of heart disease by 31%. So what's behind this unexpected health benefit?
The use of embryonic stem cells in medical research has been a hot-button moral and ethical debate for years — but there may be a way to sidestep the issue entirely. Scientists have now isolated embryonic-like stem cells in human breast milk.
A bacterium found in sewage water could revolutionize modern medicine. It's basically the bacterial equivalent of a vampire, spending its time hunting other bacteria and sucking out all their nutrients. This could revolutionize antibotics and stop the rise of "super bugs."
