Homeopathy, the pseudoscientific system of medicine, is in the headlines as King Charles has appointed a pro-homeopathy doctor to his staff.
Here's a look at its history and some of the controversies surrounding the "like cures like" doctrine, including the FDA's recommendation that homeopathic eye drops be pulled from the market, and the lawsuit against CVS and Walmart.

Breathtaking new image from JWST
About 340 years ago (Earth time) a star exploded in the constellation Cassiopeia. These are its shattered remains. Just look at the exquisite detail visible in the space telescope's view!

1. A new high-definition image from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) unveils intricate details of supernova remnant Cassiopeia A (Cas A), and shows the expanding shell of material slamming into the gas shed by the star before it exploded. The most noticeable colors in Webb’s newest image are clumps of bright orange and light pink that make up the inner shell of the supernova remnant. These tiny knots of gas, comprised of sulfur, oxygen, argon, and neon from the star itself, are only detectable by NIRCam’s exquisite resolution, and give researchers a hint at how the dying star shattered like glass when it exploded.

  from KUNews
  
  According to anthropologists and geologists at the University of Kansas, it’s time to acknowledge humans have become the dominant force shaping the moon’s environment by declaring a new geological epoch for the moon: the Lunar Anthropocene. In a comment published today in Nature Geoscience, they argue the new epoch may have dawned in 1959 when the USSR’s unmanned spacecraft Luna 2 alighted on the lunar surface.
