Scientists discovered two gut bacteria that produce serotonin and normalize digestion in mice, opening new paths to treat irritable bowel syndrome. People with IBS have lower levels of one of these bacteria.
Researchers at the University of Waterloo have engineered bacteria that naturally thrive without oxygen to invade and consume cancer tumors from their oxygen-starved cores. The breakthrough includes a safety switch that only activates the bacteria's survival mechanism when enough have gathered inside the tumor, preventing them from spreading to healthy tissue.
Scientists discovered millions of bacteria living in fog droplets that actively grow, multiply, and consume pollutants like formaldehyde. This microscopic ecosystem could be quietly improving air quality in ways we never understood before.
Researchers have cracked the code for how bacteria naturally produce powerful cancer drugs, potentially speeding development of new treatments. The breakthrough could help create better versions of existing cancer medicines with fewer side effects.
German scientists discovered three bacteria species working together to digest toxic plastic chemicals that single microbes couldn't handle. The cooperative "consortium" breaks down harmful phthalates found in everyday products, opening new doors for cleaning up plastic pollution.
Scientists discovered that living bacteria inside fog droplets actively break down air pollutants like formaldehyde, transforming our understanding of fog from sterile mist to a helpful ecosystem. These tiny air cleaners grow and multiply while purifying the air we breathe.
University of Minnesota researchers discovered how to prevent gum disease by disrupting bacterial "conversations" rather than destroying bacteria. The breakthrough could reshape how we treat infections throughout the body.
Scientists discovered living bacteria inside fog droplets that actively eat formaldehyde and other air pollutants while floating in the atmosphere. Nature might have its own microscopic air purification system working above our heads.
University of Toronto researchers discovered a single protein that both detects and destroys viruses infecting bacteria, potentially revolutionizing how we fight infections. This compact defender could help develop safer treatments for antibiotic-resistant diseases.
Scientists just proved that hardy bacteria can survive the crushing forces of asteroid impacts, bringing us closer to understanding whether life on Earth came from space. The findings could reshape how we think about life's origins and where to search for it in the universe.
Canadian researchers have created bacteria that eat cancer from the inside out, using genetic engineering to solve a problem that stumped scientists for decades. The breakthrough could offer a highly targeted way to destroy solid tumors without harming healthy tissue.
Scientists discovered E. coli bacteria can rotate tiny discs using only the swirling motion of their bodies and tails, like invisible motors working from a distance. This mind-bending finding could revolutionize how we design microscopic machines.
Scientists created jellylike capsules packed with engineered bacteria that fight infections from inside the body. The breakthrough could eliminate the need for pills and shots when treating certain infections.
Scientists in Brazil discovered that 540-million-year-old fossils once thought to be traces of early animals were actually preserved communities of bacteria and algae. The finding reshapes our understanding of when complex life first emerged on Earth.
Scientists in Egypt have discovered bacteria that can degrade one of the hardest plastics to recycle. The breakthrough could transform how we tackle toxic plastic pollution worldwide. #
Baylor University researchers have turned a common food-borne bacteria into a precision weapon against colorectal cancer, the nation's second-deadliest cancer. The breakthrough could one day be delivered as a simple oral medication.
Scientists at Baylor University have transformed a common food-borne bacteria into a powerful weapon against colorectal cancer, using modified Listeria to deliver cancer-killing toxins directly into tumor cells. The breakthrough could eventually lead to an oral cancer treatment.
Scientists discovered that certain gut bacteria during infancy appear to protect children from developing autism and ADHD, even when their genes suggest higher risk. The breakthrough opens possibilities for simple probiotic treatments that could support healthy brain development.
Michigan State University researchers have developed a copper-based surface that uses sunlight to destroy harmful bacteria without antibiotics. This breakthrough could help hospitals fight germs while reducing antibiotic resistance.
What scientists thought were 540-million-year-old traces of tiny worms turned out to be fossilized bacteria and algae, some visible to the naked eye. The discovery rewrites our understanding of when small animals first appeared on Earth.
