The historic Apollo moon missions are often associated with high-visibility test flights, dazzling launches and spectacular feats of engineering. But intricate, challenging handiwork — comparable to weaving — was just as essential to putting men on the moon. Beyond Neil Armstrong, Buzz Aldrin and a handful of other names thatContinue Reading
The idea was inspired by the connection between poor oral health and preterm birth Chewing a sugar-free gum daily reduced preterm births in a large study in Malawi. The oral intervention was inspired by past research linking poor oral health and preterm birth. The gum contains xylitol — a chemicalContinue Reading
Sending humans on deep space projects is a reality, to visit other planets and colonize them. We are technologically ready to take the first steps. Popular imagination embodied in sci-fi stories—such as “The Martian,” with a big station on the surface and Matt Damon stranded on Martian soil growing potatoes;Continue Reading
No one knew if orcas could take down the largest animal on the planet – until now Killer whales are skilled assassins, hunting everything from herring to great white sharks.
