Ultrafast camera films 3-D movies at 100 billion frames per second

In his quest to bring ever-faster cameras to the world, Caltech's Lihong Wang has developed technology that can reach blistering speeds of 70 trillion frames per second, fast enough to see light travel. Just like the camera ...

Graphene microbubbles make perfect lenses

Tiny bubbles can solve large problems. Microbubbles—around 1-50 micrometers in diameter—have widespread applications. They're used for drug delivery, membrane cleaning, biofilm control, and water treatment. They've been ...

Researchers 3-D print tiny multicolor microstructures

Researchers have developed an automated 3-D printing method that can produce multicolor 3-D microstructures using different materials. The new method could be used to make a variety of optical components including optical ...

Ripple effects after slow-motion bubble collapse

A recent feature cover photo on Science portrayed a bubble in mid-collapse, based on a study conducted by Alexandros T. Oratis et al. The research team in mechanical engineering, mathematics and aerospace engineering at Boston ...

Bubbling and burping droplets of DNA

Liquid droplets formed from DNA display a peculiar response to enzymes. An international collaboration between LMU and UCSB has now been able to explain the mechanisms behind bubble formation.

Flow-through electrodes make hydrogen 50 times faster

Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the ...
