Lab-made hexagonal diamonds are stronger than the real thing

Lab-made hexagonal diamonds are stronger than the real thing

Diamonds may be the strongest known natural material, but researchers have just created some stiff competition. By firing a dime-sized graphite disk at a wall at 15,000 mph (24,100 km/h), scientists momentarily created a hexagonal diamond that is both stiffer and stronger than the natural, cubic kind. Hexagonal diamonds, also known as Lonsdaleite diamonds, are a special type of diamond with carbon atoms arranged in a hexagonal pattern. Formed when graphite is exposed to extreme heat and stress, such as at meteor impact sites, the rare material has long been theorized to be stronger than...

How experts plan to treat the new coronavirus

How experts plan to treat the new coronavirus

As the coronavirus outbreak in China continues to spread, having infected over 24,000 people so far, scientists around the world are racing to find a treatment.

In fact, none of the handful of coronaviruses known to infect humans has an approved treatment, and people who are infected typically receive care mainly to help relieve symptoms, according to the U.S. Centers for Disease Control and Prevention (CDC).
