Scientists help probe dark energy by testing gravity

This image – the first released from NASA’s James Webb Space Telescope – shows the galaxy cluster SMACS 0723. Some of the galaxies appear smeared or stretched due to a phenomenon called gravitational lensing. This effect can help scientists map the presence of dark matter in the universe.

KARI names KPLO as it begins communication testing

The Korea Aerospace Research Institute (KARI) is preparing to launch its Korea Pathfinder Lunar Orbiter (KPLO), recently named Danuri. Danuri is South Korea’s first of many planned lunar missions in the coming future. This mission is developed and operated by KARI with contributions from NASA. A SpaceX Falcon 9 will launch Danuri on August 2, … Read more

Study gives animal testing alternatives a confidence boost

A method of screening for allergens in cosmetics, enhanced by NIST researchers, is faster than animal-based methods and boasts similar performance. But instead of relying on animals, this method involves measuring interactions between cosmetic test samples and amino-acid-like chemicals inside plastic well plates with a common laboratory device called a plate reader.

More math testing could be good for primary schoolchildren, if done in the right way

Credit: BlurryMe/Shutterstock Recently published UK government plans proposed that by 2030, 90% of children leaving primary school in England should reach the expected standards in reading, writing and math, compared with 65% in 2019. As part of efforts to achieve this, the government is introducing more testing. In June 2022, year four pupils (aged eight … Read more

Testing a new desktop’s computational power with a video game

With each passing year, we depend more and more upon computational simulations for our research work at PVL. Recently, we decided to acquire a new workstation to increase our capacity. This week, Charissa Campbell writes about her efforts to test-drive the new machine using a piece of software that would challenge its simulation capabilities: the … Read more
