Explaining Bizarre Helium 4, a Likely Supersolid

Suggesting that atoms in a solid can move or be transported through it seems as impossible as using a syringe to inject material into a billiard ball. It shouldn’t work. But it turns out to be possibl...

On quantum paths through the helium atom

This forms an essential basis for electron holography of atoms (Physical Review Letters 103, 053001).How do electrons move inside an atom and what happens in detail if this motion is distorted...

'Cold fusion' rebirth? New evidence for existence of controversial energy source

Researchers are reporting compelling new scientific evidence for the existence of low-energy nuclear reactions (LENR), the process once called "cold fusion" that may promise a new source of ...

The origin of supernovae confirmed

A star is a large ball of hot gas and in its incredibly hot interior hydrogen atoms combine to form helium, which subsequently forms carbon, other heavier elements and finally iron. When all the atoms...

Atomic Nucleus with Halo: For the First Time, Scientists Measure the Size of a One-Neutron Halo with Lasers

Atomic nuclei are normally compact structures defined by a sharp border. About twenty-five years ago, it was discovered at the University of California in Berkeley that there are exceptions to this pi...

Slow motion: antiprotons unravel atoms

Quantum mechanics makes it easy to describe hydrogen, the simplest atom, but bigger atoms are more complicated owing to interactions between their electrons. It is especially difficult to predict the ...
