Although synthetic polymers like nylon and polyester are less costly, they do not compare to silk’s natural qualities and mechanical properties.

Scientists have completed the first 3D virtual reconstruction of the ribcage of the most complete Neanderthal skeleton unearthed to date. Using CT scans of fossils from an approximately 60,000-year-old male skeleton, researchers were able to create a 3D model of the chest — one that is different from the longstanding image of the barrel-chested, hunched-over ‘caveman.’
