New additives could turn concrete into an effective carbon sink
Introducing additives to concrete manufacturing processes could reduce the sizeable carbon footprint of the material without altering its bulk mechanical properties, a study shows.

Retinal scans: A non-invasive, inexpensive method to track human aging
Is the eye a window into aging? New research has shown how imaging of the fundus, the blood vessel-rich tissue in the retina, can be used to track human aging, in a way that is noninvasive, less expensive and more accurate than other aging clocks that …

Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions
Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.
Pulsing ultrasound waves could someday remove microplastics from waterways
Colorful particles of plastic drift along under the surface of most waterways. These barely visible microplastics — less than 5 mm wide — are potentially harmful to aquatic animals and plants, as well as humans. Now, a team reports a two-stage device…

Modern origami method creates glass shapes by folding
The ancient art of origami is well known for transforming sheets of paper and other foldable materials into complex 3D shapes. But now, chemical engineers have extended the centuries-old practice to produce intricate shapes made of glass or other hard …

Early study shows cones in retinal degeneration, thought to be dormant, may retain visual function
New research in mice suggests that ‘dormant’ cone photoreceptors in the degenerating retina are not dormant at all, but continue to function, producing responses to light and driving retinal activity for vision.
