A new portable Raman analyzer can accurately measure very low concentrations of hydrogen gas in ambient air, which could be useful for detecting hydrogen leaks.

We know exercise is good for our body, but what about our brains? A new study from the University of Missouri suggests that exercise plays a crucial role in keeping our minds sharp, even when one of the brain’s key energy sources isn’t available.

The study, led by Mizzou researchers Taylor Kelty and R. Scott Rector, offers fresh insight into brain health and suggests that exercise could play a bigger role in preventing cognitive decline than previously thought.

Researchers in Nikolaus Rajewsky’s lab at Max Delbrück Center combined high-resolution, single-cell spatial technologies to map a tumor’s cellular neighborhoods in 3D and identify potential targets for personalized cancer therapy. They describe their findings in two separate papers in Cell Systems.

Researchers from the University of Shanghai for Science and Technology and the University of Illinois Urbana-Champaign have developed and validated a coupled xenon-transport and reactor dynamics model for molten salt reactors. This model enables simulations of dynamic and frequency response of liquid-fueled MSRs, which is validated against a broad spectrum of experiment data from the MSRE. The new simulation framework reveals the unique power-to-flowrate and power-to-void frequency responses of the MSRE. In addition, plant responses during the unique initiating events of off-gas system blockage and loss of circulating voids are simulated.

Plant-based seafood alternatives should have similar flavors, textures and nutritional content to the foods they mimic. And recreating the properties of fried calamari rings, which have a neutral flavor and a firm, chewy texture after being cooked, has been a challenge. Building off previous research, a team publishing in ACS Food Science & Technology describes successfully using plant-based ingredients to mimic calamari that matches the real seafood’s characteristic softness and elasticity.

The world's largest solar telescope, the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope in Hawaii, has reached an important milestone. After almost 15 years of preparation, the German instrument for the Inouye Solar Telescope, the Visible Tunable Filtergraph (VTF), has now taken its first images. The imaging spectro-polarimeter was developed and built at the Institute for Solar Physics (KIS) in Freiburg (Germany). The Max Planck Institute for Solar System Research (MPS) in Göttingen (Germany) is a partner in the project. The data published now were obtained during the technical commissioning of the instrument. VTF analyzes the sunlight captured by the Inouye Solar Telescope in more detail than ever before and, among other things, extracts information on the flow velocity of the solar plasma and the magnetic field strength at the visible surface of the Sun and in the directly adjacent gas layers above. Even in the current technical test phase, VTF is making smallest structures visible. In later scientific operation, when the data is extensively post-processed, the resolution will improve further. With a primary mirror diameter of four meters, the Inouye Solar Telescope is the largest in the world. Thanks to the optimal observational conditions on the Hawaiian volcano
