Astronomers Find ‘Impossible’ Galaxy ACDG-2 With Virtually No Stars and a Massive Dark Matter Core

Astronomers have identified CDG-2, a faint galaxy in the Perseus cluster that appears to be composed almost entirely of dark matter. Located 300 million light-years from Earth, it was discovered by tracking globular star clusters using data from Hubble, Euclid, and Subaru telescopes. Scientists estimate that about 99% of its total mass is dark matter.

Scientists Detect Rising Microplastics in Human Brains, Study Raises Concerns

Image
A rise in microplastic contamination in human brain tissue has been reported, with findings indicating an increase over recent years. Concerns about potential health impacts have been raised, as microplastics and nanoplastics have been detected in significant amounts. Research suggests that individuals with dementia had even higher concentrations, though the causation remains unclear. While the presence of these particles has been established, debates around research methodology and the accuracy of findings continue within the scientific community. Study Highlights Rising Microplastic Levels According to a study published in Nature Medicine on February 3, the concentration of microplastics in human brain tissue has risen by approximately 50 percent between 2016 and 2024. Researchers found that in those who had died with dementia, microplastic levels were nearly six times higher than in individuals without the condition. Comparisons with samples dating from 1997 to 2013 showed a co...
