Researchers have uncovered a new way bacteria detect viral attacks: a virus-produced enzyme cuts a bacterial sensor protein, triggering a self-destructing immune response. The discovery could lead to more effective phage therapies against ...
Eating more sugar while taking antibiotics was linked to greater disruption of the gut microbiome and increased growth of potentially harmful bacteria. Researchers say temporarily cutting back on sweets during and after antibiotic treatment could be ...
Scientists discovered that disrupting the chemical messages bacteria use to communicate can push dental plaque toward a healthier microbial balance. The approach could lead to new treatments for gum disease that control harmful bacteria without ...
Scientists found that five seemingly unrelated conditions, including long Covid, ME/CFS, and PTSD, may disrupt many of the same biological networks involved in immunity, metabolism, and cellular energy. The findings could help explain their shared ...
Scientists have discovered a new tick-borne virus in China that causes flu-like illness and may account for previously unexplained cases of fever, fatigue, digestive problems, and low platelet counts. Most patients with ALTNV alone recovered, but ...
Scientists resurrected antimicrobial peptides from mammals that lived millions of years ago and found that some were more potent against drug-resistant bacteria than modern human versions. These evolutionary relics could provide new clues for ...
A major Swedish study of 3.7 million people has found that rare TORCH infections passed from a pregnant woman to the fetus are linked to much higher risks of autism and intellectual disability later in life. Children with a congenital TORCH ...
Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that ...
A growing Bundibugyo virus outbreak is showing how a little-known relative of Ebola can become a major threat when diagnosis and treatment options are limited. Experts warn that preparing only for familiar pathogens could leave the world vulnerable ...
Ancient DNA reveals that plague was already killing hunter-gatherers in Siberia 5,500 years ago, long before cities and flea-driven epidemics. The prehistoric strains may have been especially ...
Long-lived bats appear to combine powerful immune defenses with unusual strategies for eliminating damaged cells, potentially helping them avoid cancer and disease for decades. Researchers hope these genetic tricks could eventually reveal new ways ...
Semaglutide, the drug found in Ozempic and Wegovy, was linked to nearly 40% fewer asthma attacks in a large real-world study. It was also associated with about 20% fewer COPD flare-ups. Researchers say GLP-1 drugs may offer respiratory benefits in ...

Low arginine levels may allow cancer cells and viruses to slip past the immune system by reducing production of a crucial cellular warning protein. In mice, arginine-rich diets led to fewer colon ...

An experimental pill prevented a measles-like virus from spreading through the air or through close contact in ferrets. It worked when given shortly before or after exposure and also shortened ...

Scientists have found a way to revive vancomycin, a powerful antibiotic that some dangerous bacteria have learned to resist. Instead of creating an entirely new drug, researchers paired vancomycin ...

Scientists uncovered how influenza A commandeers human cells, including a surprising strategy that dissolves tiny structures in the nucleus and releases proteins the virus may use to reproduce. The ...

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 ...

A naturally occurring compound found in foods such as wheat germ, mushrooms, and aged cheese may help older adults build stronger protection after vaccination. In a small pilot trial, researchers ...

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 ...

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 ...

Researchers discovered an “Achilles’ heel” shared by E. coli, Shigella, and other diarrhea-causing bacteria: enzymes they use to breach the gut’s protective mucus layer. By targeting this ...

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 ...

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 ...

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 ...

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 ...

A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can ...

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 ...

Researchers found that mRNA cancer vaccines can recruit an unexpected immune cell to launch powerful tumor-fighting responses, overturning a long-held assumption about how the vaccines work. The ...

Scientists have uncovered a surprising twist in how bacteria share genes—including those that spread antibiotic resistance. Tiny virus-like particles called gene transfer agents (GTAs), once ...

A new nanodisc-based platform lets scientists study viral proteins in a form that closely mimics real viruses, revealing how antibodies truly recognize them. This approach uncovered hidden ...

A popular Korean skincare ingredient may be far more powerful than anyone realized. Scientists have discovered that madecassic acid—derived from the herb Centella asiatica—can stop ...

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 ...
