This scanning electron microscope image shows the carbon cathode of a carbon-dioxide-based battery made by MIT researchers, after the battery was discharged. It shows the buildup of carbon compounds on the surface, composed of carbonate material that could be derived from power plant emissions, compared to the original pristine surface (inset).

Lithium-based battery could make use of greenhouse gas before it ever gets into the atmosphere. A new type of battery developed by researchers at MIT could be made partly from carbon dioxide captured from power plants...

ESA’s star mapping mission, Gaia, has shown our Milky Way galaxy is still enduring the effects of a near collision that set millions of stars moving like ripples on a pond. The close encounter likely took place sometime in the past 300-900 million years. It was discovered because of the pattern of movement it has given to stars in the Milky Way disc – one of the major components of our Galaxy.

The pattern was revealed because Gaia not only accurately measures the positions of more than a billion stars but also precisely measures their velocities on the plane of the sky...

This confocal microscopic image shows a two-month-old human esophageal organoid bioengineered by scientists from pluripotent stem cells. About 700 micrometers (0.027 inches) in size, the organoid is stained to visualize key structural proteins expressed in mature esophagus, such as involucrin (green) and cornulin (blue). Researchers report in the journal Cell Stem Cell the organoids enhance the study of esophageal disorders, personalized medical and the development of regenerative tissue therapies for people.

Tiny organoids enable personalized disease diagnosis, regenerative therapies. Scientists working to bioengineer the entire human gastrointestinal system in a laboratory now report using pluripotent stem cells to grow human esophageal organoids.

Researchers from Drexel University’s College of Engineering have developed a way to “spray paint” invisibly thin antennas from a type of two-dimensional material called MXene. The antennas perform as well or better than the ones currently used in mobile devices and RFID tags.

Engineering researchers report a method for spraying invisibly thin antennas, made from a type of two-dimensional, metallic material called MXene, that perform as well as those being used in mobile devices, wireless routers and portable transducers.

The promise of wearables, functional fabrics, the Internet of Things, and their “next-generation” technological cohort seems tantalizingly within reach...
