Researchers have identified 3,000 radioactive isotopes – and predict 4,000 more are out there.
Alongside their famous dangers, radioactive materials have many beneficial uses. With as many more predicted as have already been discovered, nuclear physicists are searching for more isotopes.
Mole Day is an unofficial holiday celebrated among chemists on Oct. 23, between 6:02 a.m. and 6:02 p.m. The time and date are derived from Avogadro’s number.
Chemists sure know how to party. And here is the proof. On October 23rd they celebrate their hallowed unit: the mole. Find out what that's all about.
Put simply, it's the outcome of a chemical reaction, which humans learned how to make some 400,000 years ago.
Map of all matter – most of which is invisible dark matter – between Earth and the edge of the observable universe.
Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.

Canada is a world leader in the field of neutron scattering, winning a Nobel Prize in 1994 for its invention. But the looming shutdown of facilities at Chalk River puts us on the sidelines.
General anesthetics affect cellular proteins to knock us out. Some do so better than others, especially the noble gas Xenon.
How do anesthetics work, and what makes for an ideal anesthetic? It's not as mysterious as once believed, and there's a gas that ticks all the boxes for a perfect anesthetic: xenon.
Magnetism is useful in many ways, and the magnetic memory effect appears even at the atomic level.

Atoms manipulated to be 4000 times larger than usual may be the tool dark-matter hunters have been waiting for.
Diamonds are a data storers’ best friend?

With current modes up against their limits, we need new data storage solutions. Tiny defects in diamonds' atomic structure might turn them into a new medium for memory.
New elements were discovered in early thermonuclear bomb tests.
New elements found in the reactions of nuclear tests during World War II sparked the hunt for additions to the periodic table.

They might only last for a fraction of a second but four new elements have finally won their place in the periodic table. The hunt is now on to find even more.

The Nobel Prize-winning research on neutrinos is expected to push the boundaries of science and technology.
What properties allow lab-made metals to flow like liquids (as in this digital art)?
These laboratory-made metals have unusual properties that consumer electronics manufacturers love. New research used high-energy X-rays to figure out why.
Element 117 is unofficially named ununseptium which is Latin for 117.
The hunt for long-lived superheavy elements has taken another leap forward now we’ve confirmed the existence of Element 117, also known as ununseptium. It was first seen briefly by a team of US and Russian…
