When, why and how did neurons first evolve? Scientists are piecing together the ancient story.
The James Webb Space Telescope (JWST) is aweing scientists and the public alike with its spectacular images of distant galaxies and its discoveries of dozens of new black holes. Yet JWST is also rewriting scientists’ understanding of objects on a slightly smaller, more relatable scale: how planets form from swirls of gas and dust around young stars.
Cells of different size classes all have a similar total mass, such that small, numerous cells such as red blood cells contribute the same amount to the body’s total mass as the largest cells, as reported by researchers in the September 18 issue of the Proceedings of the National Academy of Sciences.
Until recently, gravitational waves could have been a figment of Einstein’s imagination. Before they were detected, these ripples in spacetime existed only in the physicist’s general theory of relativity, as far as scientists knew. Now, researchers have not one but two ways to detect the waves. And they’re on the hunt for more.
Magnetars possess magnetic fields that are trillions of times stronger than those of ordinary stars. Flatiron Institute astrophysicist Christopher White comments on the work being done to pin down possible pathways to a magnetar.
Strange metals have confounded physicists since their discovery 40 years ago, suggesting that a new fundamental theory is needed to understand how they work. Now, a new study led by Flatiron Scientists claims to offer just that.
As their colonies grow, bees and wasps eventually need to increase the size of the hexagonal cells that make up their nests. But it’s hard to efficiently combine hexagons of different sizes into a single continuous array. Both the honeybees and wasps have solved this problem by mixing in some pairs of five-sided and seven-sided cells, which bridge the gap between different sizes of the six-sided hexagons.
