NASA is very interested in developing a propulsion method to allow spacecraft to go faster. We’ve reported several times on different ideas to support that goal, and most of the more successful have utilized the sun’s gravity well, typically by slingshotting around it, as is commonly done with Jupiter currently.

But, there are still significant hurdles when doing so, not the least of which is the energy radiating from the sun simply vaporizing anything that gets close enough to utilize a gravity assist. That’s the problem a project supported by NASA’s Institute for Advanced Concepts (NIAC) and run by Jason Benkoski, now of Lawrence Livermore National Laboratory, is trying to solve.

The project was awarded a NIAC Phase I grant in 2022, focused on combining two separate systems—a heat shield and a thermal propellant system. According to the project’s final report, combining those two technologies could allow a spacecraft to perform what is known as an Oberth maneuver around the sun.

Scientists have achieved a series of milestones in growing a high-quality thin film conductor, suggesting in a new study that the material is a promising candidate platform for future wearable electronics and other miniature applications.

Researchers at The Ohio State University, the Army Research Laboratory and MIT determined that the material is the best among similarly built films for its electron mobility—an index of how easy it is for an electrical current to pass through it.

Coupled with low defect density to reduce interference with electron movement on the surface, the material is like a tiny empty freeway where all the electrons can easily get where they need to go with no traffic to be seen.

In a new study, lab mice given an experimental drug were jokingly referred to as “supermodel grannies” because they looked so youthful even while aging beyond their expected lifespan.

As the BBC reports, the trials for a drug believed to flush out a protein known as interleukin-11 — which in early development helps build our bones but later in life causes the kinds of inflammation that triggers much of the illness of aging — have already had intriguing success in mice.

Published in the journal Nature, a paper about the research undertaken by scientists at Imperial College London, Duke-NUS in Singapore, and the MRC Lab of Medical Sciences found that when given a drug that purges interleukin-11, the mice became more lean, had healthier fur, and had significantly lower levels of cancer than their counterparts of the same age.
