Researchers have created a new 3D model of human embryonic tissue that promises to shed light on critical components of development—including processes that go awry during pregnancy complications.

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.

Scientists made the surprising discovery that the insects’ displeasure for touching DEET, the active ingredient in many repellents, helps prevent bites.

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.

Scientists have found that small genetic differences can cause the same gut microbe to behave differently in different people, and affect the overall health of their human hosts.

Studying microscopic worms, Rockefeller scientists have identified a brain circuit that drives repetitive behavior—providing potential clues for understanding some human psychiatric conditions.

In many cancer patients who have been treated with immunotherapy, the tumor comes back. New research identifies the cells responsible for thwarting the treatment and offers new insights into how they do it.

Recent research has shown that a drug known as MI-2 can kill cells that cause a fatal brain cancer. But only now have scientists been able to explain how the compound works: by targeting cholesterol production in tumors.
