Space-borne quantum source to secure communication

Soon, powerful quantum computers will be able to easily crack conventional mathematically encrypted codes. Entangled photons generated by a spaceborne quantum source could enable hack-proof key exchange for ultra high security ...

Pristine quantum light source created at the edge of silicon chip

The smallest amount of light you can have is one photon, so dim that it's pretty much invisible to humans. While imperceptible, these tiny blips of energy are useful for carrying quantum information around. Ideally, every ...

Team's pic of crack in the act could prevent engineering failures

In work that could help prevent the failure of everything from bridges to dental implants, a team led by a researcher at Texas A&M University has taken the first 3-D image of a microscopic crack propagating through a metal ...

On the rebound

Our bodies have a remarkable ability to heal from broken ankles or dislocated wrists. Now, a new study has shown that some nanoparticles can also "self-heal" after experiencing intense strain, once that strain is removed.

Scientist describes fundamental process when ice is compressed

Almost three-quarters of the earth's surface is covered by water. Almost two-thirds of the human body is made up of it. We drink it. We use it in our homes and in industry. As a solid, it's ice. As a gas, it's steam.

First-of-its-kind mummy study reveals clues to girl's story

Who is she, this little mummy girl? Northwestern University scientists and students are working to unravel some of her mysteries, including how her body was prepared 1,900 years ago in Egypt, what items she may have been ...

Crystals in a pink X-ray beam

A newly developed experimental set-up allows the X-ray structure determination of biomolecules such as proteins with far smaller samples and shorter exposure times than before. At so-called synchrotron sources, protein crystal ...
