Hidden patterns in electric propulsion plasma beams could help ensure the success of long-term space missions. Go faster, farther, more efficiently.

That’s the goal driving spacecraft propulsion engineers like Chen Cui, a new assistant professor at the University of Virginia School of Engineering and Applied Science. Cui is exploring ways to improve electric propulsion thrusters — a key technology for future space missions.

“In order to ensure the technology remains viable for long-term missions, we need to optimize EP integration with spacecraft systems,” Cui said.

According to management consulting firm BCG, only around half of all aluminum beverage cans are recycled in the United States, which is far behind countries such as Germany. What’s more, aluminum has one of the highest recycling rates in the U.S. — only around 19% of the durable goods sold in the U.S. are recycled, including only 14% of plastic containers and packaging. The rest is sent to landfills, where it leaches toxic chemicals into the surrounding soil and waterways.

New processes such as the one developed by the MIT researchers can hopefully make a difference in those numbers.

“We’re not just preventing waste,” said John H. Lienhard, another one of the researchers. “This membrane technology also enables a circular economy for aluminum, which could reduce the need for new mining and help mitigate some of the industry’s environmental footprint.”

A recent study has found that the overexpression of telomerase reverse transcriptase (TERT), which is a subunit of telomerase, an enzyme essential for telomere maintenance, leads to lifespan extension in mice without significant side effects [1].

Protecting DNA

Telomere shortening is a well-known hallmark of aging. Telomeres are protective DNA sequences at the ends of the chromosomes. In most human cells, they become shorter with each division.

In Intel’s second “Behind this Door” video, take a sneak peek into fab D1X in Oregon to see what is likely the most complicated machine humans have built. An extreme ultraviolet (EUV) lithography system uses radically shorter wavelengths to project circuit patterns onto silicon wafers. The #EUV machine pushes Moore’s Law forward and #chip makers cannot produce leading-edge chips without it. (Credit: Intel Corporation)

Researchers from Kyushu University, Japan have revealed how a special type of force within an atom’s nucleus, known as the three-nucleon force, impacts nuclear stability. The study, published in Physics Letters B, provides insight into why certain nuclei are more stable than others and may help explain astrophysical processes, such as the formation of heavy elements within stars.

All matter is made of atoms, the building blocks of the universe. Most of an atom’s mass is packed into its tiny , which contains protons and neutrons (known collectively as nucleons). Understanding how these nucleons interact to keep the nucleus stable and in a low energy state has been a central question in for over a century.

The most powerful nuclear force is the two– force, which attracts two nucleons at long range to pull them together and repels at short range to stop the nucleons from getting too close.
