The world’s oldest cheese has been found on the necks and chests of perfectly preserved mummies buried in China’s desert sand. Dating back as early as 1615 B.C., the lumps of yellowish organic material have provided direct evidence for the oldest known dairy fermentation method. The individuals were likely buried with the cheese so they could savor it in the afterlife. Read more

By 1920, however, Bachman’s Warbler was scarce over most of its range and only a handful of breeding birds or migrants were encountered after 1930.

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.
