Integrated electrokinetically driven microfluidic devices with pH-mediated solid-phase extraction coupled to microchip electrophoresis for preterm birth biomarkers. ELECTROPHORESIS, 2017; DOI: 10.1002/elps.201700054

With help from a palm-sized plastic rectangle with a few pinholes in it, Brigham Young University researchers are hoping to minimize the problem of premature deliveries. The small chip – integrated microfluidic device, predicts with up to 90% accuracy, a woman’s risk for a future preterm birth. “It’s like we’re shrinking a whole laboratory and fitting it into one small microchip,” said BYU chemistry Ph.D. student Mukul Sonker.

In the US alone, a half million babies are born preterm; worldwide, the number is an estimated 15 million...

1st MEMS metamaterial device displays infrared patterns that can be quickly changed. A new reconfigurable device that emits patterns of thermal infrared light in a fully controllable manner could one day make it possible to collect waste heat at infrared wavelengths and turn it into usable energy. The new technology could be used to improve thermophotovoltaics, a solar cell that uses infrared light, or heat, rather than the visible light absorbed by traditional solar cells...

A team of researchers from Georgia Institute of Technology and two other institutions has developed a new 3D printing method to create objects that can permanently transform into a range of different shapes in response to heat. The team, which included researchers from the Singapore University of Technology and Design (SUTD) and Xi’an Jiaotong University in China, created the objects by printing layers of shape memory polymers with each layer designed to respond differently when exposed to heat.

“This new approach significantly simplifies and increases the potential of 4D printing by incorporating the mec...

Artist concept of the planetary body 2014 UZ224, more informally known as DeeDee. ALMA was able to observe the faint millimeter-wavelength “glow” emitted by the object, confirming it is roughly 635 kilometers across. At this size, DeeDee should have enough mass to be spherical, the criteria necessary for astronomers to consider it a dwarf planet, though it has yet to receive that official designation.

Using ALMA, astronomers have revealed extraordinary details about a recently discovered far-flung member of our solar system, the planetary body 2014 UZ224 aka DeeDee...
