David Rockefeller, university benefactor for 76 years, dies at 101

David Rockefeller“David’s integrity, strength, wisdom, and judgment—and especially his unequivocal commitment to excellence—shaped the University and made it the powerhouse of biomedical discovery it is today,” said Russell L. Carson, chair of the Board, and Richard P. Lifton, president, in a statement. More »

For biologists studying tiny worms, new technologies make big improvements

For biologists studying tiny worms, new technologies make big improvements Two new technologies are helping scientists understand new aspects of organ and nervous system development in C. elegans. One allows them to image worms developing in a natural environment, while the other makes it possible to track single neurons as the worms grow. More »

Early intervention with new treatment provides durable control of HIV-like virus in monkeys

Early intervention with new treatment provides durable control of HIV-like virus in monkeysResearchers have found that a new approach to HIV treatment can suppress an HIV-like virus for an extended period in monkeys. The therapy employs antibodies and takes advantage of the immune system’s natural defenses. More »

Study tests the “three-hit” theory of autism

Study tests the “three-hit” theory of autismCould a genetic predisposition to autism together with early stress have a more detrimental effect on boys than on girls? In experiments with mice, researchers found evidence that three factors—genes, environment, and sex—work together to produce problems with social interaction, a hallmark of autism. More »

A new way to reset gene expression in cancer cells shows promise for leukemia treatment

A protein that often is mutated in leukemia cells could represent a potent drug targetScientists have discovered a potential new target for the treatment of leukemia that potentially could augment the activity of BET inhibitors, drugs currently in clinical trials. These therapies act on histones, DNA’s packaging proteins, to reset gene regulatory programs that go awry in cancer.

New structural studies reveal workings of a molecular pump that ejects cancer drugs

New structural studies reveal workings of a molecular pump that ejects cancer drugsSometimes cells spit out things we don’t want them to—like medications. Researchers have determined the three-dimensional structure of a tiny pump that expels, among other things, chemotherapy agents. This new knowledge could lead to the design of more effective drugs.

New research explains why a common bacterium can produce severe illness

New research explains why a common Staphylococcus bacterium can produce severe illnessHow can the same infection result in dramatically different levels of illness in two different people? A new study identifies two conditions—a genetic immunodeficiency and delayed acquired immunity—that explain why a patient developed a life-threatening disease in response to a common strain of bacterium.

Crowdsourcing effort helps researchers predict how a molecule will smell

Crowdsourcing effort helps researchers predict how a molecule will smellWhile it’s possible to anticipate the color of light or the pitch of sound, odor defies prediction. New research has taken an important step toward decoding smell, by linking a scent back to a molecule’s chemistry.

Scientists discover an unexpected influence on dividing stem cells’ fate

Scientists reveal an unexpected influence on dividing stem cells' fateWhen it divides, a stem cell has a choice: produce more stem cells or turn into the specific types of cells that compose skin, muscle, brain, or other tissue. New experiments in skin show this decision can be altered if tiny organs within cells aren’t positioned and divvied up properly. More »

Study reveals the structure of a protein crucial for DNA replication

Study reveals the structure of a protein crucial for DNA replicationFor life to propagate, the instructions in our DNA must be copied and passed on to future generations. Focusing on the structure of the machinery that executes this process, scientists have revealed that the orientation of the proteins involved is different from what has previously been reported.
