Scientists Reveal The First Images of Atoms ‘Swimming’ in Liquid

Scientists Reveal The First Images of Atoms 'Swimming' in Liquid

The motion of single atoms through liquid has been caught on camera for the first time. Using a sandwich of materials so thin they’re effectively two-dimensional, scientists trapped and observed platinum atoms ‘swimming’ along a surface under different pressures. The results will help us better understand how the presence of liquid alters the behavior of … Read more

Physicists Are Startled by This Magnetic Material That ‘Freezes’ When Heated

Physicists Are Startled by This Magnetic Material That 'Freezes' When Heated

When disordered magnetic materials are cooled to just the right temperature, something interesting happens. The spins of their atoms ‘freeze’ and lock into place in a static pattern, exhibiting cooperative behavior not usually displayed. Now for the first time, physicists have seen the opposite. When fractionally heated, the naturally occurring magnetic element neodymium freezes, turning … Read more

Astronomers Unveil The Most Detailed Map of The Metal Asteroid Psyche Yet

Astronomers Unveil The Most Detailed Map of The Metal Asteroid Psyche Yet

If you wanted to do a forensic study of the Solar System, you might head for the main asteroid belt between Mars and Jupiter. That’s where you can find ancient rocks from the Solar System’s early days. Out there in the cold vacuum of space, far from the Sun, asteroids are largely untouched by space … Read more

What Is Monkeypox, and Is There a Cure?

Photo: Cuson (Shutterstock) Smallpox is the only disease we’ve ever managed to fully eradicate in humans; it hasn’t existed anywhere in the world since 1980. But its close relative, monkeypox, is still around. Monkeypox isn’t anywhere near as dangerous as smallpox, but a few recent outbreaks have public health officials worried. In recent weeks, there … Read more
