Bird-banding data in North America shows a spring migration pattern that's become progressively earlier with each of the last 5 decades, and a fall migration that's lasting longer than 50 years ago.
These hot, dust-laden winds are known as “la calima” and happen most often in winter. They can blow at up to 75 mph (120 kph). The dust kicked up last weekend in Africa drifted over the Canary Islands, shutting down airports and stranding travelers.
A new study from researchers in the Netherlands shows how scientists can detect exoplanets orbiting red dwarf stars, and learn about their environments, from the radio waves generated by auroras on those worlds.
New research suggests that early humans in Africa interbred with a ghost population that likely split from the ancestors of humans and Neanderthals between 360,000 and 1.02 million years ago.

One hundred million years ago, a bee got trapped in tree resin. Over time, geological forces converted the resin to amber. Now a scientist arrives on the scene, to tell us this bee’s story.
