A new result from the molecular gas survey in the Southern Pinwheel Galaxy M83 using the Atacama Large Millimeter/submillimeter Array (ALMA) Telescope reveals a discovery of 10 high-velocity clouds composed of molecular gas, moving at velocities significantly different from M83’s overall rotation, an indication that the influx of these gases—which help to form stars—are from outside the galaxy.

Scientists have studied a new target for antibiotics in the greatest detail yet—in the fight against antibiotic resistance. The “molecular machine” flagellum is essential for bacteria to cause infection, allowing bacteria to “swim” around the bloodstream until finding something to infect. But it could also be a target for antibiotics.

The phenomenon is created by the shifting play of light and shadow over the lunar surface.

While the current generation of artificial intelligence chatbots still flub basic facts, the systems answer with such confidence that they’re often more persuasive than humans. Adults, even those such as lawyers with deep domain knowledge, still regularly fall for this.
