Scientists discover gene that could save bananas from deadly Panama disease - ScienceDaily

A massive asteroid slammed into the North Sea roughly 43 to 46 million years ago, triggering a tsunami more than 100 meters (330 feet) high. Now, after more than two decades of scientific disagreement, researchers have uncovered compelling evidence confirming the ancient collision. The impact created what is now known as the Silverpit Crater, a massive structure buried deep beneath the seafloor. Although scientists first discovered it in 2002, its origins remained fiercely debated, with some researchers arguing that geological processes, rather than an object from space, were responsible.

As the U. S. and Europe increasingly shift away from animal research, organoids have been touted as a promising alternative method for studying the brain. The field has made significant progress since human brain organoids debuted in 2013. Researchers can now coax these clusters, fashioned from stem cells, to integrate a variety of cell types, including microglia, astrocytes and interneurons. They can even fuse brain-region-specific organoids into structures called assembloids that closely resemble circuits within the brain.
