Scientist’s accidental exhale leads to improved DNA detector
Greg Madejski held his breath as he looked into the microscope, trying to weld two fingernail-sized chips together: a tiny chip containing a nanofilter on top of another chip with a DNA sensor. It was frustrating work. The chips weren’t making good contact with each other. Madejski gently poked at the chips, then peered over...

Scientists Create Living 3D Printer Ink Made of Live Bacteria
Rod-shaped bacteria produce cellulose, recognizable as a thread-like structures. Researchers at ETH Zurich in Switzerland have reported in journal Science Advanceson a way of 3D printing materials infused with live bacteria. The development may lead to devices such as implantable blood filters and bacterial factories that produce biomolecules for drugs and other therapies. A myriad of...

This Temporary Tattoo Is Made From Living Cells
It’s a little more high-tech than the tattoos you might remember fishing out of the bottom of a Cracker Jack box as a kid. Engineers at MIT have developed a temporary tattoo that’s 3-D printed with living ink. The tattoo is made up of bacterial cells that are genetically programmed to light up when exposed to different...

Soft robotic sleeve hugs the heart to keep it beating – and could save patients from a lifetime on post-surgery drugs
Currently, pumps are made of tough material, and the blood has to run through them, increasing infection risk This device lightly squeezes the heart to help it keep pumping blood It could prevent lopsided pumping that causes the other half of the heart to fail It could also allow patients to forego debilitating post-surgery drugs...

High-Strength Artificial Cartilage Made from Kevlar
Researchers at the University of Michigan and Jiangnan University in China have developed a type of artificial cartilage using Kevlar, a synthetic fiber better-known for its use in bullet-proof vests, and polyvinyl alcohol (PVA), a material used in hydrogel cartilage replacements. The new hybrid material combines the strength and water content of natural cartilage, and...

A delicate crossing: Controller developed to open the blood-brain barrier with precision
Representation of the drug delivery system. Serving as the acoustic indicator of drug delivery dosage, the microbubble emission signal y(t) is used to find the expected controller output u(f) which is fed back to help control ultrasound …more The blood-brain barrier – the semi-permeable membrane that surrounds the brain – offers important protection for a...
