Researchers solved a long-standing mystery behind how a bacterial toxin associated with colorectal cancer damages the colon. The toxin first binds to a receptor called claudin-4, giving it access to attack the cells' protective barrier. After identifying this weak point, the team

Researchers at Queen Mary University of London have discovered that tiny photosynthetic bacteria band together into protective "herds" when attacked by predators—a survival strategy that could also influence how carbon is stored in the world's waters.

Researchers have discovered that a microscopic skeleton inside neurons does much more than hold cells together. It acts as a gatekeeper that controls what brain cells absorb and when they absorb it. When this protective structure weakens, neurons rapidly take in harmful proteins

Often called the silent thief of sight, glaucoma is a group of eye diseases that gradually damage the optic nerve, often without warning signs. It is linked to increased pressure (ocular hypertension) inside the eye and, if left untreated, can lead to permanent vision loss. Even

Fear is often thought of as a negative emotion but is actually a natural protective response to perceived threats or danger. It helps us survive. When we experience a situation that causes fear, it becomes stored in our brain as a fear memory. These fear memories prevent us from

Children who have been in contact with dogs in early childhood are, on average, healthier and require fewer courses of antibiotics than children without such contact. The protective association is explained, at least in part, by the spread of dog-associated microbes in the home.

Andes virus, the type of hantavirus responsible for the outbreak on the MV Hondius cruise ship earlier this year, has a fatality rate of up to 36%. Precautions such as isolation of infected individuals and use of personal protective equipment by health care personnel can prevent

The fever experienced by people with malaria exposes parasites to high temperatures within blood cells. This heat can lead to the accumulation of damaged proteins inside the parasite and trigger protective mechanisms against thermal stress.

Australian researchers have discovered that even a modest reduction in the protein BECLIN1 leads to a significant increase in gut inflammation, which can lead to further disease and complications over time.

Crowd of more than 22,000 people – and the musician himself – filled Hyde Park with the ‘largest gathering of people wearing bald caps’A tight plastic cap is not an attractive option for protective headwear in 30C (86F) heat. Yet 22,141 people opted for just that – along with a w

NASA's nuclear-powered mission to Mars is taking shape with the selection of Firefly Aerospace to design and manufacture the protective aeroshell that will shield the Skyfall spacecraft's descent stage during its plummet through the Martian atmosphere.
