In theory, a tumor is an army of clones, made up of many copies of the original cancerous cell. But tumor cells don’t always act like duplicates, and their unpredictable behavior can create problems for treatment. For while some cells within a tumor succumb to anti-cancer drugs, others may surviv...

Once HIV-1 has hijacked a host cell to make copies of its own RNA genome and viral proteins, it must assemble these components into new virus particles. The orchestration of this intricate assembly process falls to a viral protein known as Gag. For one thing, Gag must be able to discernÌýviral RNA...

Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destroy...

Viruses are masters of outsourcing, entrusting their fundamental function – reproduction – to the host cells they infect. But it turns out this highly economical approach also creates vulnerability. Researchers at Rockefeller University and their collaborators have found an unexpected way the...

Forget the five-million plus commuters and untold number of rats – many of the living things crowded into the New York City subway system are too small to see. An interest in the more menacing among these microbes led high school student Anya Dunaif, a participant in Rockefeller’s Summer Science...

Drugs for HIV have become adept at suppressing infection, but they still can’t eliminate it. That’s because the medication in these pills doesn’t touch the virus’ hidden reserves, which lie dormant within infected white blood cells. Unlock the secrets of this pool of latent virus, scientists...

Colorectal cancer is a cancer on the move: about 50 percent of patients with the disease see their cancer spread, typically to the liver. By identifying genes that become activated in cancer cells that successfully travel —Ìýmetastasize —Ìýto the liver, researchers at Rockefeller have implicated...

Axons connect neurons with each other to form the neural networks that underpin the vital functions of perception, motility, cognition, and memory. In many neurodegenerative disorders, from traumatic injury or toxic damage to diseases such as Alzheimer’s or Parkinson’s disease, axonal degenerati...

A regime of anti-HIV drugs —Ìýcomponents of regimens to treat established HIV infection —Ìýhas the potential to protect against infection in the first place. But real life can interfere; the effectiveness of this prophylactic approach declines if the medications aren’t taken as prescribed. ...

A face is more than a static collection of features. A shift in gaze, a tightening of the lips, a tilt of the head, these movements convey important clues to someone’s state of mind. Scientists know that two particularly social and visual creatures, humans and rhesus macaque monkeys, have a netwo...
