Regenerative Electronic Biosensors

Scientists Develop Electronic Biosensors That Can Be Regenerated and Reused Repeatedly

In a newly published study, scientists detail the development of electronic biosensors that can be regenerated and reused repeatedly. Imagine a swarm of tiny devices only a few hundred nanometers in size that can detect trace amounts of toxins in a water supply or the very earliest signs of cancer in the blood. Now imagine […]

Researchers Develop Transistors without Semiconductors

Researchers Develop Transistors without Semiconductors

By placing nanometer sized quantum dots of gold across on the tops of the boron nitride nanotubes, researchers at Michigan Tech created a quantum-tunneling device that acts like a transistor at room temperature without using semiconducting materials. For decades, electronic devices have been getting smaller, and smaller, and smaller. It’s now possible—even routine—to place millions […]

New Observations Help Astronomers Learn How Young Stars Accrete Material and Grow

 Astronomers Gain New Insights into How Young Stars Grow

New observations of our Sun, combined with computer modeling, have helped astronomers resolve a decade-long argument over how to measure the accretion rates of growing stars. Cambridge, Massachusetts – On June 7, 2011, our Sun erupted, blasting tons of hot plasma into space. Some of that plasma splashed back down onto the Sun’s surface, sparking […]
