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 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.
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.
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.
Researchers have assembled a new and improved DNA catalogue for the mosquito Aedes aegypti. This tool will help researchers understand the insect’s biology, and may lead to new strategies for preventing diseases like Zika and dengue.
A new study shows that embryonic cells retain a memory of the chemical signals to which they are exposed. Without these memories, cells fail organize into distinct tissue types.
