Mathematically speaking, the way a tiger charges a herd of antelope resembles a white blood cell attacking a colony of bacteria. That’s the conclusion of a new paper by an international team of physicists, just published in Journal of Physics A: Mathematical and Theoretical.
E. coli, salmonella, and staph are the names Americans fear when it comes to nasty foodborne illnesses. Yet it’s norovirus that is, far and away, the most common cause of food poisoning in the US. So why aren’t Americans more afraid of it?
Sean Parker, the billionaire co-founder of Napster and the first president of Facebook, announced a $250 million initiative to accelerate the development of effective cancer treatments—and he’s asking the country’s top scientists to pitch in and openly share their research findings.
Researchers have developed a laser that spots illness-inducing bacteria before it makes you sick.
It sounds ripped out of the pages of a science fiction novel—or maybe a Lisa Frank catalog—but the genetically modified, brilliantly colored zebra fish pictured above is no fantasy. It was created by scientists, to explore one of the most elusive processes in biology: tissue regeneration.
A surprising new genetic study shows that some people with naturally high levels of HDL cholesterol—the supposedly good kind of cholesterol—are at increased risk of a heart attack. Doctors are now further questioning the use of drugs to boost HDL levels while looking to new therapies to reduce heart risk.
Scientists have used stem cells to cure blindness in rabbits—which could be incredible news for visually impaired people.
We’re all looking forward to interstellar travel and colonizing Mars, but first, we’ve got a lot to learn about how the human body responds to the cold dark void of outer space. Scott Kelly’s stint on the ISS, which ends tomorrow, is helping us answer some critical questions—including what weightlessness does to our…
A decade after its introduction, the vaccine for human papillomavirus has reduced the prevalence of this cancer-causing STD in teenage girls by nearly two-thirds. It’s an incredible success story, leading experts to question why HPV vaccinations aren’t more common in the United States.
Can we harness the mind to reduce side-effects and slash drug costs?
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.
