Six-foot-five, 500-plus pounds of metal, yet nimble enough for its wearer to maneuver under the sea and study delicate luminescent jellyfish without harming them: This is the Exosuit, and this summer the hulking outfit will carry a scientist down to 1000 feet below the ocean’s surface, to a remote place where glowing fish flash signals to one other through the dark.
For people in too many developing countries, clean water is often a luxury. Chlorine treatments are too expensive for small villages, boiling requires a hefty investment in fuel, and UV radiation demands regular high-tech maintenance. But now, scientists say that a simple, inexpensive water filter might be only a tree branch away from reality.
Archaeologists find cheese on 3,600-year-old mummies
NBC News: Archaeologists have found clumps of cheese tucked into the necks and chests of Chinese mummies up to 3,600 years old.
Researchers collected samples of material from 10 tombs in northwestern China’s Taklamakan Desert. Chemists then analyzed the material and determined that it was a type of kefir cheese. Scientists believe it was probably left behind as tribute or food for the afterlife.
Although not the earliest evidence of cheese-making, these are the oldest known specimens of cheese.
