Scientists from the UChicago show that some neurons in bird brains form the same kind of circuitry and have the same molecular signature as cells that enable connectivity between different areas of the mammalian brain. The researchers found that alligators share these cell types as well, suggesting that while mammal, bird and reptile brains have very different anatomical structures, they operate using the same shared set of brain cell types.
In a new study in the journal Science, researchers from UChicago show how thousands of short RNA molecules with diverse genetic sequences serve as security guards to thwart attempts to invade the genome.
Specific strains of intestinal bacteria can improve the response rate to immunotherapy for patients being treated for advanced melanoma. Patients with a higher ratio of the “beneficial” bacteria to “non-beneficial” bacteria all showed a clinical response: a reduction in tumor size.
