Shigella bacteria can infect humans but not mice. In the March 29 issue of Nature, a team from UConn Health explains why. Their findings may explain the multifariousness of a key weapon of our immune system. Shigella infections cause fever,…

In humanity's ongoing quest for the elixir of life, the science keeps pointing to stem cells. Research increasingly shows that maintaining stem cell fitness promotes a long healthspan, and new findings show keeping stem cells clean and tidy…

Most life on Earth is based on polymers of 20 amino acids that have evolved into hundreds of thousands of different, highly specialized proteins. They catalyze reactions, form backbone and muscle and even generate movement. But is all that…

Proteins are the heavy-lifters of biochemistry. These beefy molecules act as building blocks, receptors, processors, couriers and catalysts. "Proteins are the molecular machines that power all life on Earth," explained Mark Sherwin, a…

Despite recent advancements, many highly sensitive diagnostic tests for viral diseases still require complicated techniques to prepare a sample or interpret a result, making them impractical for point-of-care settings or areas with few…

As conventional antibiotics continue to lose effectiveness against evolving pathogens, scientists are keen to employ the bacteria-killing techniques perfected by bacteriophages, the viruses that infect bacteria. One major challenge standing…

Certain diseases, including Alzheimer's, are currently considered "undruggable" because traditional small molecule drugs can't interfere with the proteins responsible for the illnesses. But a new technique that specifically targets and…
