UV Radiation, Autoimmunity, and Questions Galore
Stacie Zoe Berg | May 4, 2003 | 6 min read
John Choate, Chizzy Graphics It's an interesting conundrum: The effects of ultraviolet (UV) radiation from sun exposure can induce the onset of, or exacerbate, the symptoms of certain autoimmune diseases. Now flip the coin: UV also can prevent, or reduce, the symptoms of others. Current research focuses on lupus, multiple sclerosis (MS), type 1 diabetes, rheumatoid arthritis, inflammatory bowel disease, dermatomyositis, and atopic eczema. What is going on? "These irradiations may alter the d

Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.
Researchers in George Church&rsquo;s lab modified wild type ADK proteins (left) in <em >E.coli</em>, furnishing them with an nonstandard amino acid (nsAA) meant to biocontain the resulting bacterial strain.

Genetic Mutations Can Be Benign or Cancerous—a New Method to Differentiate Between Them Could Lead to Better Treatments
Ryan Layer, The Conversation | May 27, 2022 | 5 min read
Tumors contain thousands of genetic changes, but only a few are actually cancer-causing. A quicker way to identify these driver mutations could lead to more targeted cancer treatments.

DEINO-MITE CLEANUP In 1956, investigators discovered a potentially invaluable cleanup tool in an unlikely place. A hardy bacterium called Deinococcus radiodurans unexpectedly thrived in samples of canned meat thought to be sterilized by gamma radiation. The b
