A common birthplace of new genes, the male testes are a hotspot for biological innovation. Within these organs, scientists have found a trove of virgin genetic sequences—and a better understanding of how evolution moves forward.
Cell division is critical to creating and sustaining life. It’s also incredibly difficult to study. Now, advanced technology is enabling researchers to take their understanding of this process to the next level.
Scientists have found a group of brain cells that influence body mass in two ways, by controlling how much we eat as well as how much energy we burn. The findings could lead to new drugs to help people shed weight.
To fight off invading viruses, bacteria have evolved a slew of creative defense tactics. New research shows that in some cases, microbes go to great lengths to keep an infection from spreading, even destroying bits of their own genetic material.
Scientists have discovered a curious phenomenon taking place in mouse skin: cells compete with one another for the chance to develop into mature tissue. The findings indicate that this antagonism is key to creating healthy skin.
Rockefeller scientists have identified a genetic condition that makes people prone to developing tuberculosis. In a British population, they found that the condition underlies one percent of cases of the disease—a finding that may ultimately lead to new treatment options.
