When a human cell divides, every chromosome has a handle. A structure at its waist, the centromere, is what the machinery of division grips to pull one copy into each of the two new cells. The rings…

In 1961 Rolf Landauer worked out what it costs to forget. Erasing a bit of information carries a physical price that no better engineering can get under: memory is matter, and clearing it gives off…

People later diagnosed with early-onset Alzheimer's disease, the form that begins before old age, had been treated more often for vertigo, depression and several other conditions in the one to five…

A group at Institute of Science Tokyo has made a methane catalyst from five rare earth metals mixed into a single oxide, and reports that, in laboratory tests, it gave ethylene and ethane in about…

The pistol shrimp is one of the most extreme creatures on the planet. Despite its modest size of 3 to 5 centimeters, it shoots jets of water, creates blinding flashes of light, jams military sonar,…

Researchers at Baylor College of Medicine and collaborators at four other institutions report that two DNA changes sitting outside the MECP2 gene, in the switches that set how much of it a cell…

Ask an engineer for a network that computes well, survives the loss of its parts and stays cheap, and the answer is that you will have to choose. The three demands fight one another. Extra…

Researchers in Japan report that mice given olive oil before a dose of glucose emptied their stomachs more slowly and showed a smaller early rise in blood sugar than mice given the same oil after the…

Iron-starved Arabidopsis plants change which chemicals they release into the soil according to how acidic their surroundings are, and the bacteria living on their roots then use those chemicals to…

The U.S. Geological Survey's Hawaiian Volcano Observatory reported on Oct. 8, 2026, in Science that the amount Kīlauea's summit swells between bursts of lava tracks when the next burst begins, a…

Ask how an artificial neural network learns and the answer begins with a decision somebody made. A person lays out the layers. A person writes the rule that adjusts each connection when the network…

A team led from the Max Planck Institute for Biology Tübingen reports that the bacteria in a person's gut are linked to whether that person runs a fever after an mRNA vaccination. The study,…
