New stretchable solar cells will power artificial electronic 'super skin'

24 Feb 19:00

"Super skin" is what one researcher wants to create. She's already developed a flexible sensor that is so sensitive to pressure it can feel a fly touch down. Now she's working to add the ability to detect chemicals and sense various kinds of biological molecules. She's also making the skin self-powering, using polymer solar cells to generate electricity. And the new solar cells are not just flexible, but stretchable -- they can be stretched up to 30 percent beyond their original length and snap back without any damage or loss of power.

Entire T-cell receptor repertoire sequenced revealing extensive and unshared diversity

24 Feb 19:00

T-cell receptor diversity in blood samples from healthy individuals has been extensively cataloged for the first time, setting the stage for a better understanding of infectious disease, cancer, and immune system disorders.

Bedside ultrasound becomes a reality

24 Feb 19:00

Clinicians have often referred to ultrasound technology as the "stethoscope of the future," predicting that as the equipment shrinks in size, it will one day be as common at the bedside as that trusty tool around every physician's neck. According to a new report, that day has arrived.

Needle-in-a-haystack search identifies potential brain disease drug

24 Feb 19:00

Scientists who examined more than 10,000 chemical compounds during the last year in search of potential new drugs for a group of untreatable brain diseases, are reporting that one substance shows unusual promise. The early positive signs for so-called prion diseases come from research in laboratory mice and cell cultures.

Quantum simulator becomes accessible to the world

24 Feb 19:00

Experimental physicists have put a lot of effort in isolating sensitive measurements from the disruptive influences of the environment. In an international first, Austrian quantum physicists have realized a toolbox of elementary building blocks for an open-system quantum simulator, where a controlled coupling to an environment is used in a beneficial way. This offers novel prospects for studying the behavior of highly complex quantum systems.
