A new theory suggests the utility of a memory for future situations dictates its location in the brain, either in the hippocampus or the neocortex.…
The findings shed light on the mechanism by which drugs such as ibuprofen and aspirin alleviate flu symptoms and suggest that the drugs may even…
The hindbrain is a region of the brain that controls basic vital functions such as heart rate, respiration, and balance. The hindbrain is considered the…
Eating only during your most active time of day, while following a reduced-calorie diet, may lead to a substantially longer life, according to new research…
After More Than 20 Years, Scientists Have Finally Solved the Full-Length Structure of a Janus Kinase
After More Than 20 Years, Scientists Have Finally Solved the Full-Length Structure of a Janus Kinase
When a cytokine (green) binds to receptors (teal), two parts of the Janus kinase protein (pink) come together, activating it to send signals inside a…
A California reptile shop began breeding Mr. Frosty in 2016 and produced a colony of lemon-yellow leopard geckos. The color variety was known as Lemon…
A variety of molecules protrude from the cell surface, including glycoproteins, glycolipids, and the newly discovered glycoRNAs. This illustration depicts RNA as a double-stranded stem…
New DNA sequencing technologies and assembly methods let researchers read the entire genomes of 25 species: pale spear-nosed bat, greater horseshoe bat, Egyptian fruit bat,…
Researchers engineered cells to carry either a protein (green) from SARS-CoV-2 or its human target ACE2 (magenta). When near each other, the cells’ membranes fused.…
To visualize cellular signals within a neuron, researchers scattered reporters in clusters (green) across the cell. They then identified the signal each cluster represented (multiple…
A female mosquito has finely tuned senses that help her find the blood meal she needs in order to reproduce. New research reveals how the…
After centuries of breeding, tomatoes now take all sorts of shapes and sizes, from cherry-like to hefty heirloom fruit. Scientists are teasing out at the…
A potential COVID-19 treatment targets the runaway immune response seen in some severely ill patients. Researchers hope a common prescription drug will block immune cells…
The virus that causes COVID-19, called SARS-CoV-2, shown here in an electron microscope image, can trigger severe cases of infection in some younger patients. Studying…
A puma kitten, at home in her nursery, peers through a hole in a redwood log in the Sana Cruz Mountains. Scientists have now sequenced…
Cells that eventually become neurons (red, orange, and yellow spheres) migrate during embryonic development. The migrating baby neurons that build the spinal cord are color-coded…
