THE 3,500-YEAR-OLD MANCHOPPERS ON MARS HOLD KEY TO FINDING TRACES OF LIFETuesday, August 9, 2022In today’s newsletter, we explore how helicopters have changed the search for life on Mars, examine the alarming rise of monkeypox, meet the 3,500-year-old man, get a peek inside Leonardo da Vinci’s notebooks … and discover that spiders can dream.PHOTOGRAPH BY NASA/JPL-CALTECH/MSSS
How can humans better search for life on Mars? By expanding the fleet of Martian aircraft. The dazzling deployment of NASA’s Ingenuity helicopter last year paved the way for a new pair of special choppers to find—and help retrieve—Martian samples. “Ingenuity has far exceeded anyone’s wildest imaginations,” NASA’s Teddy Tzanetow says. (It’s pictured above, in this “selfie” from the Perseverance rover.)
Nat Geo’s Nadia Drake says NASA’s excitement has been fueled by recent discoverieson Mars. Even though prospects of current life may be dim, scientists think it’s possible that extinct life left traces in the rock—and the durability of Ingenuity has stoked NASA’s hopes.

IN THE SPOTLIGHT PHOTOGRAPH COURTESY OF DANIELA C. RÖSSLER Do spiders dream? Yes, scientists say, at least the jumping spider (E. arcuata) does. Ecologist Daniela Rößler, first spotting the napping spiders near her home, told Nat Geo she was struck by the way they switched while sleeping—like dogs or cats. (In the image above, see the spider curling its legs during an REM sleep-like state.)
WHAT DO THEY DREAM?SMARTER PLANETPHOTOGRAPH BY ADEL NEWMAN, ALAMY Are beachfront resorts making it worse? The world’s 7,000 beachfront resorts operate on the front lines of rising seas, coastal erosion, and destructive storms. Some make it worse. The high shoreline towers block the flow of sand, for example. Author Sarah Stodola recommends tourists stay farther back from the beach, travel to shorelines closer to home, and frequent places turning to low-impact building methods and sustainable practices, such as Malaysia’s Tioman Island (pictured above).

BEAUTIFUL BEACHESIN A FEW WORDS
LAST GLIMPSEPHOTOGRAPH BY @NICHOLESOBECKIThe case for trees: See this tree in the Luki Biosphere Reserve in the Democratic Republic of the Congo? It’s over 800 years old. As its seed first took root, Genghis Khan was invading China and King John was signing the Magna Carta. The world’s second largest rainforest, the Congo Basin could unlock vital solutions for climate adaptation—or with its leaders’ decision to open it up for large-scale logging, become a ticking carbon time bomb if its resources are mismanaged. Nat Geo Explorer Nichole Sobecki took this image for our coverage of the vital topic.
