How does sunscreen work on the atomic level?

The long – but not too long – cavity would ping-pong X-ray pulses inside of a particle accelerator facility to help capture nature’s fastest movements.

The reanalysis considered new types of particle collisions and how dark matter particles interact with the Earth. 

Researchers demonstrate a way to remove the potent greenhouse gas from the exhaust of engines that burn natural gas.  

It irons out wrinkles in thin films of these novel superconductors so scientists can see their true nature for the first time. 

The results should further our understanding of similar reactions with vital roles in chemistry, such as the production of vitamin D in our bodies.

The results offer important implications for astrophysics and nuclear fusion research.

A low-cost, recyclable powder can kill thousands of waterborne bacteria per second when exposed to sunlight. Stanford and SLAC scientists say the ultrafast disinfectant could be a revolutionary advance for 2 billion people worldwide without access to safe drinking water.

The first pair of towers are now at the Ontario facility, where they'll further the hunt for dark matter particles.

Chemical reactions often involve intermediate steps that are too fast and complex for us to see  – even using our most advanced scientific instruments. Combining two X-ray spectroscopy techniques has now been shown to change that.

After decades of effort, scientists have finally seen the process by which nature creates the oxygen we breathe using SLAC’s X-ray laser.

The algorithm pairs machine-learning techniques with classical beam physics equations to avoid massive data crunching.
