Inside the brains of hungry worms, researchers find clues about how they hunt

When looking for food, the roundworm C. elegans searches the same area for up to 20 minutes before trying its luck at more distant locales. New research on the worm’s brain explains how this behavior arises at the level of molecules and cells.

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.

New findings could make mosquitoes more satisfied—and safer to be around

Scientists have learned new tricks that could be useful in preventing mosquito-borne illnesses such as Zika and yellow fever. A new study shows that some appetite-reducing drugs can curtail the insects’ impulse to feed on warm-blooded hosts.

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.

In simple bacteria, scientists find new evidence of complex immunity

Bacteria use a multifaceted immune response to get rid of invading DNA. In a new study, researchers identify an enzyme that can destroy foreign genetic material capable of evading a microbe’s first line of defense.

Enzyme structure reveals how DNA is opened up for transcription

DNA’s two strands must be separated before its code can be read, or transcribed. By studying the structure of the enzyme RNA polymerase, researchers have elucidated how DNA unwinds and becomes legible.

Study identifies genetic mutation responsible for tuberculosis vulnerability

Scientists discovered a genetic variant that greatly increases a person’s likelihood of developing tuberculosis. Their research elucidates how this mutation affects the immune system, and points to a possible treatment for people with the disease.

Year in review: 10 science stories to remember

Rockefeller researchers accomplished a lot this year. We look back at 10 of the most exciting science stories of 2018.

Study explains how geckos gracefully gallop on water

Geckos are amazingly agile. In addition to running across land and up trees, the animals can prance across the surface of water. A new study reveals how they do it.

Shape-shifting protein protects bacteria from invaders

Researchers have discovered how bacteria manage to destroy enemy DNA, while keeping their own genetic material safe.
