Hubble Reaches New Milestone in Mystery of Universe's Expansion Rate
Pursuit of the universe's expansion rate began in the 1920s with measurements by astronomers Edwin P. Hubble and Georges Lemaître. In 1998, this led to the discovery of "dark energy," a mysterious repulsive force accelerating the universe's expansion. In recent years, thanks to data from Hubble and other telescopes, astronomers found another twist: a discrepancy between the expansion rate as measured in the local universe compared to independent observations from right after the big bang, which predict a different expansion value.

Innovative Textile Vents to Release Heat When you Sweat
Scientists have developed a lightweight material that traps thermal energy when dry, but opens a series of tiny vents to let heat escape when a person starts sweating. The vents close again to retain heat once they are dry.

Wearable Head Scanner for Comfort, Mobility During Brain Scans
To collect accurate images of a patient's brain, the patient must be still and confined in a tube-like MRI scanner for a long period of time. To better assess their brain function and behavioral health, however, they should move naturally and freely during a scan. Researchers have proposed a solution to both clearly visualize and accurately assess the brain via photoacoustic imaging with a stretchable, flexible material.

Fully Recyclable Printed Electronics
Engineers have developed the world's first fully recyclable printed electronics. By demonstrating a crucial and relatively complex computer component — the transistor — created with three carbon-based inks, the researchers hope to inspire a new generation of recyclable electronics to help fight the growing global epidemic of electronic waste.

Robotic Dragonfly to Detect Oil Spills and Acidity
Engineers have developed an electronics-free, entirely soft robot shaped like a dragonfly that can skim across water and react to environmental conditions such as pH, temperature or the presence of oil. The proof-of-principle demonstration could be the precursor to more advanced, autonomous, long-range environmental sentinels for monitoring a wide range of potential telltale signs of problems.

3D Printing Used to Develop a new Instrument for Eye Imaging
OCT, or optical coherence tomography, produces slices of image data that can be stacked to produce a 3D representation of the tissue of interest. In the context of retinal imaging, it produces cross-sectional views of the retina that allow the ophthalmologist to readily visualize subsurface features of the retina that are much more difficult to visualize in two-dimensional en face, or top-down views.
