Researchers develop a skin printer that works like a paint roller, depositing bio ink that speeds up wound healing. A new handheld 3D printer can deposit sheets of skin to cover large burn wounds – and its “bio ink” can accelerate the healing process.

The device, developed by a team of researchers from the University of Toronto Engineering and Sunnybrook Hospital, covers wounds with a uniform sheet of biomaterial, stripe by stripe.

The bio ink dispensed by the roller is composed of mesenchymal stroma cells (MSCs) — stem cell...

A “beating heart” of frozen nitrogen controls Pluto’s winds and may give rise to features on its surface, according to a new study.

Pluto’s famous heart-shaped structure, named Tombaugh Regio, quickly became famous after NASA’s New Horizons mission captured footage of the dwarf planet in 2015 and revealed it isn’t the barren world scientists thought it was.

Now, new research shows Pluto’s renowned nitrogen heart rules its atmospheric circulation...

New antiviral materials m lade from sugar have been developed to destroy viruses on contact and may help in the fight against viral outbreaks.

This new development from a collaborative team of international scientists shows promise for the treatment of herpes simplex (cold sore virus), respiratory syncytial virus, hepatitis C, HIV, and Zika virus to name a few. The team have demonstrated success treating a range of viruses in the lab – including respiratory infections to genital herpes.

The research is a result of a collaboration between scientists from The University of Manchester, the University of Geneva (UNIGE) and the EPFL in Lausanne, Switzerland...

New lithium metal anode could improve the longevity and energy density of future batteries. New research by engineers at MIT and elsewhere could lead to batteries that can pack more power per pound and last longer, based on the long-sought goal of using pure lithium metal as one of the battery’s two electrodes, the anode.

The new electrode concept comes from the laboratory of Ju Li, the Battelle Energy Alliance Professor of Nuclear Science and Engineering and professor of materials science and engineering...
