The discovery that the brain has different systems for representing small and large numbers provokes new questions about memory, attention and mathematics.

A new analysis of ancient sediments fills a gap in the fossil record — revealing a massive dynasty of ancient eukaryotes, which may have reigned for 800 million years and shaped the history of life of Earth.

The Nobel Prize in Chemistry has been awarded to three researchers who harnessed the quantum behaviors of semiconductor nanocrystals.

Katalin Karikó and Drew Weissman have been awarded the 2023 Nobel Prize in Physiology or Medicine for discoveries leading to mRNA vaccines, such as those that protect against Covid-19.

The preferred “handedness” of biomolecules could have emerged from biased interactions between electrons and magnetic surfaces, new research suggests.

By watching “minimal” cells regain the fitness they lost, researchers are testing whether a genome can be too simple to evolve.

The reshuffling of neurons during fruit fly metamorphosis suggests that larval memories don’t persist in adults.

To buffer the brain against menaces in the blood, a dynamic, multi-tiered system of protection is built into the brain’s blood vessels.

New experiments show that the brain distinguishes between perceived and imagined mental images by checking whether they cross a “reality threshold.”
