Old electronics and solar panels could become a new, domestic source for critical and strategic materials through Intel-E-Waste, a startup whose technology builds on foundational research from Penn State.

Johns Hopkins University engineers have created robots the size of a pencil tip intended to travel through the body to deliver medicine to infections inside a beating heart.

The bots, designed to replace risky open-heart surgery and ineffective IV-drug therapy to treat life-threatening heart infections, could also be used to less invasively and more precisely treat other hard-to-reach diseases including cancer.

Researchers from Rutgers, IBM and collaborating institutions have shown that a quantum computer can check what is happening inside it and respond while it is running, repeatedly resetting parts of the system to bring chaotic behavior under control.

The advance is a critical step toward building larger, more reliable quantum computers. 

Today’s quantum computers operate according to the unusual rules governing atoms and other extremely small particles. They could one day solve problems beyond the reach of conventional computers — designing better batteries and cleaner industrial catalysts, simulating molecules and materials too complex for today’s computers, and running certain artificial intelligence programs.

In a study published in Nature Physics, researchers from Rutgers, International Business Machines Corp., and collaborating institutions showed that a quantum computer can repeatedly check and reset parts of itself while running. The experiment is among the largest demonstrations to date of real-time quantum feedback control, a capability considered essential for future quantum computers that will be fault tolerant. 

UC San Diego biologists have unraveled the genetic adaptation that gave butterflies the ability to see rich, vivid color in their environment. The genetic change produces an additional photoreceptor that expands color vision for locating nectar and other butterflies.
