Was Neanderthal life violent? This wound suggests lethal fighting was more common

   From :-  BBC News By :-   Pallab Ghosh   Science Correspondent Edited by :- Amal Udawatta University of Cambridge A wooden spear caused the hole in this Neanderthal shoulder blade, scientists say A Neanderthal who died 75,000 years ago may have been struck through the chest by a sharpened wooden spear, archaeologists say. They say a 15mm hole found in a shoulder blade in a cave in Iraqi Kurdistan could be the earliest evidence of lethal violence involving such a weapon. From the angle of the wound and other evidence, the researchers believe the spear entered the individual's chest and passed through the body - probably damaging a lung and major blood vessels - and exited through the left shoulder blade to leave a near-perfect hole. The research is the latest in emerging evidence that suggests Neanderthal societies experienced more violence than previously thought. Neanderthals were a separate species of humans that went extinct around 40,000 years a...

'One of the great unsolved mysteries of science': What general anaesthetic reveals about our brains

                                                 From : BBC World News                                              By :  Jasmin Fox-Skelly                                           Edited by : Amal Udawatta BBC/ Serenity Strull/ Getty Images How general anaesthetics work is still not fully understood, but they are revealing clues about the nature of consciousness. In 1797, the British naval commander Admiral Horatio Nelson had his right arm amputated. The operation saved his life. But according to legend the only anaesthetic he was offered was a swig of rum .  For the majority of human history, even the removal of limbs was done on patie...

Did Venus eat its own moon?

     From : Space.Com By :  By Robert Lea Edited by : Amal Udawatta a small grey orb explodes while crashing into a larger reddish-brown orb (Image credit: Robert Lea (created by Canva)) "An interesting aspect is that a heavier moon is destroyed faster,  since a massive moon would drain Venus's spin so efficiently that it  hastens its destruction." Scientists may finally know why Venus, Earth's twin, lacks a moon, finding that the hottest planet in the solar system may have consumed its own natural satellite. Venus is often referred to as Earth's twin due to its size, mass, rocky composition, and distance from the sun, but there are some glaring differences between the two planets. Aside from Venus' blisteringly hot temperature, which could melt lead, incredible surface pressure, violent high-speed winds, and clouds of sulfuric acid, one of the key differences between Earth and Venus can be seen from afar. While our planet has a constant companion in the ...
