Astronomers Just Got Closer to Unravelling The Mystery of 'Glitching' Pulsars
A peculiar hiccup in the rotation speed of a dead star has turned out to be even more interesting than we thought. For the first time, astronomers have shown that the rotation of the Vela pulsar slowed down immediately before its 2016 glitch.

For The First Time Ever, Scientists Have Made a Stable Ring of Pure Carbon
Carbon can be arranged in a number of configurations. When each of its atoms is bonded to three other carbon atoms, it's relatively soft graphite. Add just one more bond and it becomes one of the hardest minerals known, diamond. Chuck 60 carbon ato
Bubble Experiment Finds Universal Laws
Physicists have found examples of “universality” in a system of confined bubbles. The work could help researchers understand the strange behavior of singularities.
Each time a drop drips from a faucet, nature performs a magic trick. Breaking one blob into two calls for passage through a singularity — a single point where physical quantities flirt with the infinite. As the neck connecting the two blobs thins to nothing, the fluid pressure and speed race upward toward infinity, as if they were being divided by zero. Here, the equations used to describe fluids suffer a mathematical explosion. Order returns only after the sudden break.

Scientists Just Traced Antibiotic Resistance Millions of Years Into The Past
New research has traced the history of antibiotics and antibiotic resistance back some 350-500 million years, a study in deep microorganism genealogy that could help in our current battle to contain the rise of superbugs.

Earth May Have Supported Life Much Earlier Than We Thought, Study Suggests
Early Earth grew up in a chaotic time. As our planet tried to find its place in a relatively young Solar System about 4.5 billion years ago, it was under constant attack from waves of comets, whizzing asteroids, and even some failed proto-planets.

A Mathematical Model Unlocks the Secrets of Vision
Mathematicians and neuroscientists have created the first anatomically accurate model that explains how vision is possible
Information from the eye passes through a bottleneck before it gets to the brain’s visual cortex, which heavily processes the sparse signal.
This is the great mystery of human vision: Vivid pictures of the world appear before our mind’s eye, yet the brain’s visual system receives very little information from the world itself. Much of what we “see” we conjure in our heads.
“A lot of the things you think you see you’re actually making up,” said Lai-Sang Young, a mathematician at New York University. “You don’t actually see them.”
Yet the brain must be doing a pretty good job of inventing the visual world, since we don’t routinely bump into doors. Unfortunately, studying anatomy alone doesn’t reveal how the brain makes these images up any more than staring at a car engine would allow you to decipher the laws of thermodynamics.
