POSTECH reveals how mosaic partial reprogramming enhances wound repair responses.

The human genome is about two meters long, yet it fits inside a nucleus only ~10 micrometers in diameter. A research team led by Kazuhiro Maeshima reports that linker histone H1—traditionally thought to form rigid chromatin structures—acts instead as a dynamic liquid-like “glue” in living human cells. Combining single-nucleosome imaging with computational modeling, the study shows that H1 organizes chromatin into a fluid, accessible structure.

Salk Institute scientist Sreekanth Chalasani, PhD, has received an award of up to $41.3 million from the Advanced Research Projects Agency for Health (ARPA-H) to transform his lab’s sonogenetics discovery—using ultrasound to precisely control mammalian cells—into a potential new therapy for a number of human conditions, such as peripheral neuropathies.

Researchers have discovered a new species of glassfrog in Ecuador – the Dajomes glassfrog – named after Neisi Dajomes, the first Ecuadorian woman to receive an Olympic gold medal, which she won in Tokyo 2020 in women's 76 kg weightlifting. Mylena Masache, a Biology student of the Pontificia Universidad Católica del Ecuador, and colleagues, describe the frog in a new study published April 8, 2026 in the open-access journal PLOS One.

Scripps Research chemists solve a longstanding problem in the construction of branched molecular frameworks, unlocking a faster path to the complex structures found in drugs and materials.

From seahorses to sharks, more than 3,000 fish species have been caught in bottom trawls, including many at risk of extinction, according to a new global inventory. 

In a new study published in Nature, researchers describe the extraordinary preservation of the oldest known costal breathing system in a mummified fossil from the early Permian period. The mummified fossil, which is only a few inches long, preserves not only bones, but also three-dimensional skin, calcified cartilage, and — most astonishingly —protein remnants that predate the previous oldest-known example by nearly 100 million years.
