| Spectacular bird’s-eye view? Hummingbirds see diverse colors humans can only imagine
Posted: 15 Jun 2020 12:51 PM PDT While humans have three color cones in the retina sensitive to red, green and blue light, birds have a fourth color cone that can detect ultraviolet light. A research team trained wild hummingbirds to perform a series of experiments that revealed that the tiny birds also see combination colors like ultraviolet+green and ultraviolet+red.

| New light shed on intelligent life existing across the galaxy
Posted: 15 Jun 2020 06:27 AM PDT Is there anyone out there? This is an age-old question that researchers have now shed new light on with a study that calculates there could be more than 30 intelligent civilizations throughout our Galaxy. This is an enormous advance over previous estimates which spanned from zero to billions.

| Discovery of oldest bow and arrow technology in Eurasia
Posted: 12 Jun 2020 02:22 PM PDT The origins of human innovation have traditionally been sought in the grasslands and coasts of Africa or the temperate environments of Europe. More extreme environments, such as the tropical rainforests of Asia, have been largely overlooked, despite their deep history of human occupation. A new study provides the earliest evidence for bow-and-arrow use, and perhaps the making of clothes, outside of Africa approximately 48-45,000 years ago — in the tropics of Sri Lanka.
