Researchers have uncovered an unexpected antiviral defense system in sea anemones that works very differently from the one humans use. The discovery suggests evolution developed multiple ways to combat viruses, challenging long-held ideas about how ...
Researchers uncovered why H5N1 bird flu attacks cows’ udders instead of their lungs: the virus’s preferred receptors are concentrated in mammary tissue. The breakthrough could help scientists predict future bird flu jumps and spot unusual ...
Researchers found that highly drug-resistant bacteria from hospitals are also resistant to glyphosate, a commonly used weedkiller. The discovery suggests that agricultural herbicides may be helping ...
Two dangerous viruses are back in the spotlight, reminding health officials how quickly infectious diseases can become serious threats. Hantavirus, often linked to rodents, can cause severe heart and lung complications and has no specific treatment ...
Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks. By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early ...
A new experimental vaccine developed by Scripps Research could offer a powerful new way to prevent fentanyl overdoses by stopping the drug before it reaches the brain. Rather than targeting only fentanyl itself, the vaccine trains the immune system ...
A potentially dangerous tapeworm linked to severe, cancer-like disease has now been found in the Pacific Northwest, marking its first detection in wild animals along the U.S. West Coast. Researchers ...
Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including SARS-CoV-2, ...
Melanoma may not become steadily more dangerous with age as scientists once assumed. In a surprising discovery, researchers found that cancer spread was lowest in young mice, surged in middle-aged mice, and then dropped again in very old mice. The ...
A new brain imaging study has found no evidence of widespread brain inflammation in patients suffering from prolonged symptoms after COVID-19 infection. Instead, the most severe long COVID symptoms ...
Scientists are uncovering a surprising link between hidden tooth infections and blood sugar problems. Deep infections around tooth roots can create chronic inflammation that spreads through the body and may interfere with insulin function. Studies ...
Scientists at the University of Maryland, Baltimore County, have uncovered a crucial trick used by enteroviruses—the group behind diseases like polio, myocarditis, encephalitis, and even the common cold—to reproduce inside human cells. The team ...

A breakthrough urine test could dramatically speed up how doctors treat urinary tract infections, identifying the right antibiotic in under six hours instead of waiting days. By testing directly from ...

Scientists have identified a potential new weapon against hepatitis E, a virus with no approved treatment and tens of thousands of deaths each year. The drug bemnifosbuvir, currently in trials for ...

Antibiotics are accumulating in a major Brazilian river, especially during the dry season when pollution becomes more concentrated. Scientists even detected a banned drug inside fish sold for food, ...

A shingles vaccine might double as a powerful heart protector. In people already at high risk, it cut major cardiac events by 46% and deaths by an impressive 66% within a year. Scientists think ...

A major clinical trial has delivered an unexpected twist in the search for ways to fight COVID-19 and its lingering effects. Researchers at Mass General Brigham found that taking high doses of ...

mRNA vaccines saved millions of lives during COVID-19 but have limitations like waning immunity and complex production. Scientists are now testing a new platform called DoriVac, which uses folded DNA ...

A severe case of COVID-19 or influenza could increase the risk of lung cancer later on, according to new research. Scientists discovered that serious viral infections can alter immune cells in the ...

Scientists have uncovered a crucial weakness in the malaria parasite that could open the door to new treatments. Researchers identified a protein called Aurora-related kinase 1 (ARK1) that acts like ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial ...

Researchers are engineering bacteria to invade tumors and consume them from the inside. Because tumor cores lack oxygen, they’re the perfect breeding ground for these microbes. The team added a ...

Scientists have revealed how the body’s microscopic cold sensor, TRPM8, detects both chilly temperatures and the cooling effect of menthol. The discovery finally shows how the sensation of ...

Scientists at Stanford Medicine have unveiled a bold new kind of “universal” vaccine that could one day protect against everything from COVID-19 and the flu to bacterial pneumonia and even common ...

Deep inside a Romanian ice cave, locked away in a 5,000-year-old layer of ice, scientists have uncovered a bacterium with a startling secret: it’s resistant to many modern antibiotics. Despite ...

In medieval Denmark, people could pay for more prestigious graves closer to the church — a sign of wealth and status. But when researchers examined hundreds of skeletons, they discovered something ...

Northwestern researchers have shown that when it comes to cancer vaccines, arrangement can be just as important as ingredients. By repositioning a small fragment of an HPV protein on a DNA-based ...

Researchers tracked more than 400 toddlers to see whether mRNA COVID-19 vaccination during or just before pregnancy was linked to autism or developmental delays. After detailed assessments of speech, ...

Antibiotic resistance is racing toward a global crisis, with “superbugs” projected to cause over 10 million deaths annually by 2050. Now, scientists at UC San Diego have unveiled a powerful new ...

A common bacterium best known for causing pneumonia and sinus infections may also play a surprising role in Alzheimer’s disease. Researchers found that Chlamydia pneumoniae can invade the retina ...

Scientists in Australia have uncovered a clever new way to fight some of the most dangerous drug-resistant bacteria by targeting a sugar that exists only on bacterial cells. By designing antibodies ...

As bird flu continues to circulate in animals and spill over into humans, researchers are racing to stop it before it adapts to spread widely between people. A new nasal spray vaccine showed strong ...
