Researchers discover a weakness in a rare cancer that could be exploited with drugs

Researchers have identified a rare type of cancer cell that cannot make cholesterol, a key nutrient. By targeting this deficiency, scientists may be able to develop new strategies for treating the disease.
Infections caused by methicillin-resistant Staphylococcus aureus (pictured), can lead to serious health complications. Lysins help fight such infections by destroying the bacterium’s cell wall (green), thereby killing the microbe.

Lysin therapy offers new hope for fighting drug-resistant bacteria

Increasingly, bacteria do not succumb to antibiotics. Rockefeller researchers have developed a new class of antimicrobial drug, lysin, with one compound showing promising results in a clinical trial—suggesting that an alternative to antibiotics may be on the horizon.
Researchers have mapped more than 20 different cell types present in the first-trimester human placenta, including stromal and endothelial cells (red).

First mapping of cells in the early human placenta to advance research on problem pregnancies

Scientists have made the first comprehensive inventory of cells present in the human placenta of the first trimester, a stage when many pregnancy complications are thought to arise. The findings could fuel new research on conditions such as preeclampsia and pre-term birth.

Genetic mutation identified as culprit in rare infectious disease

Researchers have uncovered the genetic factors that make some people susceptible to Whipple's disease, an intestinal inflammatory disorder that causes diarrhea, pain, and weight loss.

From infection-dodging stem cells, new tactics for research on viral disease

Among other superpowers, stem cells have a knack for fending off viruses like dengue and zika. Scientists have gained new insight into these curious defense strategies—knowledge they say could fuel the development of drugs against a range of diseases.

Scientists caution that a rare childhood liver cancer can spread to the brain

A new report details three cases of secondary brain tumors in people with fibrolamellar hepatocellular carcinoma. The researchers say imaging tests could improve treatment for patients whose cancer spreads to the brain from the liver.

In brief: Tweaking RNA protects cells from harmful inflammation

New research has helped explain what goes wrong in Aicardi-Goutières syndrome, a rare brain disorder. Patients with the disease have genetic abnormalities that may put their cells at risk of accidentally triggering an antiviral response.

In brief: Mutation explains why some people are more vulnerable to viral brain infection

Scientists identified mutations in a single gene that impair immunity to viruses in a region of the brain called the brain stem.
