Back in September, researchers in the UK discovered that brain disorders such as Alzheimer’s may be transmissible through certain medical procedures. Skeptical scientists urged caution, but now a different set of autopsy results have shown the same thing.
Chipotle announced it will be closing up shop nationwide for a few hours as part of its attempt to halt its ongoing E. Coli outbreak. But why hasn’t the company been able to stop the outbreak, or even find the source yet? The answer isn’t in the restaurant chain—it’s in the bacteria.
Another amazing year of science has come and gone, so it’s time to look ahead and see what the next year has in store. Here are Gizmodo’s most anticipated scientific and technological developments of 2016.
Fat cells secrete the hormone leptin as a means of signaling the brain when we’re full after eating. But new research indicates that leptin may also play a role in motivating us to exercise as well—possibly contributing to the phenomenon of “runner’s high.”
We have a vaccine against the virus that causes cervical cancer. It’s as safe as any other vaccine, and getting it for your tween son or daughter—or yourself, if you’re in your early twenties—is a no-brainer. Don’t buy into bogus exposés on “dangers” that don’t really exist.
Snap, crackle, pop: the sound of cracking knuckles is familiar to everyone, but scientists are having a hell of a time figuring out what causes it. A new ultrasound imaging study offers additional clues, but no definitive answers.
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.
We’re making progress in the fight against HIV around the world, but it’s still very unevenly distributed. And the United Nations’ brand new report on HIV infections among teenagers in Asia is pretty upsetting. Some 50,000 Asian teens (aged 15-19) became HIV-positive in 2014 alone, and a total of 220,000 adolescents…
Patients are increasingly bringing their fitness-tracker data to their checkups. Not only are doctors ill-equipped to deal with this information—they’re skeptical that it’s even useful.
A new genetic analysis of human gut bacteria is turning up some really weird critters—so weird, in fact, that some biologists are speculating we’ve found an entirely new domain of life. We should take that possibility with a healthy dose of skepticism. But here’s why it’s even being discussed.
What happens to your brain when you have no sense of up? Researchers are scanning the brains of astronauts to track just how badly space messes with our ability to think.
Intestinal worms have an incredibly bad reputation. The thought of them sneaking around inside our bodies and eating us from the inside is pretty unpleasant. But for decades, results coming out of lab after lab have shown that some kinds of helminths can be extremely beneficial to their host, and aren’t parasites at…
A startling report by an international team of scientists suggests that processed meats like hotdogs and bacon are a definite cause of cancer, while red meat is a probable cause. Here’s what this means to your health and why you have no reason to panic.
Genetic testing company 23andMe is back in the business of direct-to-consumer health testing kits, after a two-year semi-hiatus (in the U.S., at least) from offering health risk assessments at the behest of the Food and Drug Administration. That makes 23andMe the first such company to win FDA approval for taking its…
AIDS was a terrifying mystery, and then we solved it. When researchers identified the human immunodeficiency virus as the reason why young, previously healthy people were developing rare cancers and wasting away, it was a triumph of medical science.
Your lips are dry, so you apply a little something soothing from a tube or a tiny jar or one of those weird golf ball things. Aah, relief. But as soon as it wears off, you need more. The cycle repeats all winter. Are you practicing responsible skin care, or have you become addicted?
In Dungeons & Dragons, every character has certain strengths and weaknesses, determined by their ability scores: Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma. Your real-life self is made up of those abilities too, and you can level them up just like you do in-game.
In June of 1994, a convicted child molester named Charlie Taylor moved into a small apartment in downtown Hamilton, Ontario, Canada, across the street from a community center. He had no family. He had no parole officer. At the time, sex offenders deemed too dangerous to be let out of prison early were, paradoxically,…
Bad news, hypochondriacs: You’re walking in a massive cloud of bacteria. In fact, it’s kinda an extension of your body, and no amount of showering will rid you of it. Even better: It grew out of your mouth, poop and skin.
Not long ago, the idea of walking up to a clerk behind a counter and getting a baggie of weed seemed ludicrous. Now, in states where recreational or medical marijuana is approved and regulated, it’s a routine, mundane part of life. Are psychedelics next?
