Ancient Humans May Have Evolved a Remarkable Trick to Survive The Last Ice Age - ScienceAlert

Chinese scientists have unearthed a fossil of the earliest known flightless bird, offering compelling evidence that not all early birds evolved to take to the skies. The discovery could also challenge long-held assumptions – including ideas dating back to evolutionary theorist Charles Darwin – that flightlessness in birds arose only as a secondary adaptation after earlier species had mastered flight. The 150 million-year-old fossil of the Late Jurassic avialan Yuezhuornis yangyuanensis found in...

A viral trend promoting the placement of hair claw clips on eyebrows has captivated millions seeking fast headache relief without prescription drugs. If you have spent any time scrolling social media lately, you have probably spotted people clamping plastic claw clips directly onto their faces. It looks like an eccentric comedy sketch, but videos demonstrating this unusual trick have racked up more than 9 million views. Desperate headache sufferers are flooding comment sections, calling the clip an emergency rescue tool when nothing else works. The sudden viral craze makes total sense when you consider the sheer scale of head pain. According to the World Health Organization, recurrent headache disorders affect roughly 40 percent of the global population, touching over 3.1 billion people. Neurological data reveals that migraines alone disable more than 1.16 billion people worldwide. With nearly 29.5 percent of frequent sufferers battling rebound headaches from overuse of prescription or over-the-counter pills, people are hungry for alternatives that do not come in a pill bottle.

image: From biological camouflage to multispectral signature management and adversarial attacks on AI vision, each advance in perception has driven new ways to stay unseen. A research team led by Professor Yongxiang Liu at the National University of Defense Technology recently published a review article titled ‘The Evolution of Anti-Visual Perception: Biomimetics, Spectral Physics, and Artificial Intelligence’ in National Science Review. The review introduces anti-visual perception as a unifying concept, bringing biomimetic camouflage, multispectral signature management, and adversarial attacks on machine vision into one framework.

After using a technique called molecular clock analysis, researchers have proposed that the origin of animals could be 200 million years earlier than thought.

New research is reshaping scientists' understanding of bat evolution, with evidence suggesting that bats most likely originated in Europe during the late Paleocene, roughly 65 to 60 million years ago. For decades, researchers have debated where bats first appeared. Africa, Asia, and North America have all been proposed as possible birthplaces.
