Tokyo, Japan – Researchers from Tokyo Metropolitan University have developed a way to treat ageing-related muscular atrophy using regenerative medicine. Conventional methods to implant myoblasts, precursors to muscle fiber, required prior scarring for the new cells to graft properly. By adding extracellular matrix (ECM) fluid into the implant, the team successfully grafted myoblasts onto healthy muscle in mice. Their technique opens the way for using implantation to treat unscarred muscle atrophied by ageing.

The clownfish-anemone living arrangement is one of the most widely recognized examples of symbiosis. Researchers have made a breakthrough in understanding how anemonefish can live safely among sea anemones without being stung by their venomous tentacles, solving a century-long mystery. Scientists at the Okinawa Institute of Science and Technology (OIST) and their international collaborators have discovered that anemonefish have evolved to maintain very low levels of sialic acid in their skin mucus to avoid triggering the release of nematocysts (stinging cells) in their sea anemone hosts. The researchers found that sea anemones also lack these sugar compounds in their own mucus, likely to avoid stinging themselves. Their findings, published in the journal BMC Biology, suggest anemonefish might be using a similar protective strategy to their hosts. 

Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently, as reported by the researchers from Science Tokyo, Japan. This effectively aligns with the growing demand for speed and efficiency, accelerating the widespread deployment of wireless devices. This enables synergistic operation of wireless electronic devices and better quality of modern life.Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently, as reported by the researchers from Science Tokyo, Japan.

In a paper published earlier this month in Physical Review Letters, a team of physicists led by Jonathan Richardson of the University of California, Riverside, showcases how new optical technology can extend the detection range of gravitational-wave observatories such as the Laser Interferometer Gravitational-Wave Observatory, or LIGO, and pave the way for future observatories. 

University of Chicago Pritzker School of Molecular Engineering (UChicago PME) researchers have explored a "quantum-inspired" technique to make the "ones" and "zeroes" for classical computer memory applications out of crystal defects, each the size of an individual atom. This turns milimeter-sized crystals into computer memory devices capable of storing terabytes of data. This interdisciplinary revolution in computer memory took its inspiration from the radiation dosimeters worn by hospital employees working with X-ray machines.

The process of separating useful molecules from mixtures of other substances accounts for 15% of the nation’s energy, emits 100 million tons of carbon dioxide and costs $4 billion annually.

In a new study, researchers at Case Western Reserve University have found these manufactured separation materials don’t function as intended because the pores are so packed with polymer they become blocked. That means the separations are inefficient and unnecessarily expensive.

As more satellites, telescopes, and other spacecraft are built to be repairable, it will take reliable trajectories for service spacecraft to reach them safely. Researchers in the Department of Aerospace Engineering in The Grainger College of Engineering, University of Illinois Urbana-Champaign are developing a methodology that will allow multiple CubeSats to act as servicing agents to assemble or repair a space telescope. Their method minimizes fuel consumption, guarantees that servicing agents never come closer to each other than 5 meters, and can be used to solve pathway guidance problems that aren’t space related.
