Archaeologists claim to have discovered hidden chambers behind the walls of Tutankhamun’s tomb in a radar survey. The find resurrects a controversial theory that the young king’s burial place connects to a larger tomb containing his mother-in-law Nefertiti, whose resting place has never been found. Although not all researchers are convinced the hidden rooms exist, Egyptologist Nicholas Reeves says if the ancient queen is found to have been buried like a pharaoh, “it could be the biggest archaeological discovery ever.”

The number of people infected globally has topped 75,000, more than 74,000 of them in China.

Although he publicly clashed with prominent anti-religious figures such as Richard Dawkins, he is known for championing the ideas of Galileo and Darwin, and challenging intelligent design. “If they respect the results of modern science,” Coyne once wrote, “religious believers must move away from the notion of a dictator God or a designer God, a Newtonian God who made the universe as a watch that ticks along regularly.”
