A single fiber actuator inspired by human muscles

Assembly of 100 strands of artificial muscle fiber bundle structure on a glass slide. Credit: Kim et al. To effectively replicate the movements of humans and animals, robots must incorporate muscle-like structures. These artificial muscles must achieve optimal performance for all relevant actuation parameters, including energy density, tension, stress and mechanical resistance. Researchers from KAIST …

Diabetic status alters the impact of a single nucleotide polymorphism associated with NAFLD

Diabetic status alters the impact of a single nucleotide polymorphism associated with NAFLD

Non-alcoholic steatohepatitis (NASH) is a common disease that affects nearly one billion people worldwide. Early identification of susceptible individuals is therefore essential for precision hepatology. In this issue, Takebe et al. to use human liver organoids and perform mass population-based phenotypic analysis under insulin-insensitive conditions to study the main genetic factors of NASH. In the …

Lost and found: how a single clue led to the rediscovery of a crab not seen in 225 years

Jfinding rare species thought to be extinct is never easy, but when Pierre A Mvogo Ndongo traveled to Sierra Leone in January 2021 in search of “lost” species of land crabs, the impression of searching for a needle in a haystack was particularly powerful due to the size of the “haystack”. For one of the …

A single Hubble image captured a supernova at three different times

A single Hubble image captured a supernova at three different times

Enlarge / On the left, the full Hubble image. On the right, various images of the gravitationally lensed object. NASA, ESA, STScI, Wenlei Chen, Patrick Kelly Over the past few decades, we have gotten much better at observing supernovae as they occur. Orbiting telescopes can now pick up emitted high-energy photons and determine their source, …
