Astronomers scan exoplanet K2-18b for alien signals in most powerful search yet

Astronomers have conducted an unusually powerful radio survey of exoplanet K2-18b, one of the most promising worlds in the search for extraterrestrial life, using both the VLA and MeerKAT telescopes. The scan represents one of the most comprehensive searches for technosignatures ever attempted. Separately, researchers found that eating chili peppers may raise the risk of esophageal cancer, and a new species of monkey was identified in the Democratic Republic of Congo, marking only the fifth new monkey species found in Africa in 75 years.
