Researchers at UC Berkeley have identified a nearly complete museum skull as Adelphailurus kansensis, an early saber-toothed cat that lived in North America more than 5 million years ago. The discovery, described in the Journal of Vertebrate Paleontology, gives scientists a rare look at a little-known branch of the cat family before saber teeth reached…

FEBRACE announced that Brazilian student Beatriz Maria Ferreira dos Santos won third place in Plant Sciences at Regeneron ISEF 2026 for an orchid cultivation project that reportedly made in vitro growth about 90% faster than commercial methods. The work centers on a low-cost medium made with plant extracts, a practical idea aimed at one of…
A study in Science reports that tiny 300-million-year-old hatchlings from Mazon Creek preserve a rare glimpse of how some early relatives of land animals began life. The fossils point to direct development, a life cycle in which young animals grow as small versions of their adult form, giving paleontologists a new window into the deep…
Researchers at Nagoya University have identified an unexpected self-modifying behavior in a brain-related enzyme, according to a study in the Journal of Biological Chemistry. The enzyme, called ST8Sia5L, can build a long sugar chain on itself. That chain then helps control whether the enzyme stays quiet, leaves the cell and later becomes active again. The…
