In 10 seconds, an AI model detects cancerous brain tumor often missed during surgery

Sciencedaily.com

Drosophila study uncovers molecular details of how cell death is controlled during epithelial tissue remodeling

Phys.org 

When complex multicellular organisms grow and develop, their tissues must undergo remodeling. As new cells begin to proliferate, old cells must be removed to make room and maintain tissue balance and function. One example of this is in the Drosophila (fruit fly) abdominal epithelium during metamorphosis, where larval epidermal cells (LECs) are replaced by histoblasts, which are the precursors of the adult cells.

Three galactic 'red monsters' in the early Universe

Sciencedaily.com 

Astronomers have identified three ultra-massive galaxies -- nearly as massive as the Milky Way -- already in place within the first billion years after the Big Bang. This surprising discovery was made possible by the James Webb Space Telescope's FRESCO program, which uses the NIRCam/grism spectrograph to measure accurate distances and stellar masses of galaxies. The results indicate that the formation of stars in the early Universe was far more efficient than previously thought, challenging existing galaxy formation models.

The secrets of fossil teeth revealed by the synchrotron: A long childhood is the prelude to the evolution of a large brain

Sciencedaily.com 

Could social bonds be the key to human big brains? A study of the fossil teeth of early Homo from Georgia dating back 1.77 million years reveals a prolonged childhood despite a small brain and an adulthood comparable to that of the great apes. This discovery suggests that an extended childhood, combined with cultural transmission in three-generation social groups, may have triggered the evolution of a large brain like that of modern humans, rather than the reverse.
