The syndrome that has struck hundreds of thousands of Americans in recent years is a potentially life-threatening reaction to a sugar found in red meat. It is spread by the Lone Star tick (above) and often not diagnosed by health professionals.
Unlike most allergies, it doesn’t strike until hours after eating—and can put you at risk of anaphylaxis. How can we determine if we have it? How can it be treated?
Hint: Not a rhino: Medieval artists in Europe had to rely on oral and written descriptions to draw animals they’ve never seen, including the 13th century illustrations above. Do you know what animal they were trying to draw?
Two of our nation’s critical lifelines—the Rio Grande and Colorado Rivers—are shrinking tragically with every passing day. National Geographic Photographer Pete McBride is on a mission to protect these vital rivers and their ecosystems. An effort from Finish Dishwashing is also helping to raise awareness of the crisis affecting freshwater resources everywhere.
Repellent, anyone? If you think this summer’s mosquitoes are bad, then steer clear of Alaska’s North Slope. Above, photographer and Nat Geo Explorer Joel Sartore, while on assignment in 2006, took off his shoes and let the bugs bite—all for the pic. “They piled on so thick they made a crackling sound,” he wrote. This image became one of the most talked about photos of his career.
Justice, finally: No doctor told cancer patient Henrietta Lacks that her genetic material would be “stolen” from her dying body. Nor did they tell her family later. ”Had they been a white family they would have been treated differently,” her biographer, Rebecca Skloot, told us in 2013. This week, 72 years after her death, her descendants reached a settlement with a science and tech company that profited from research on her amazing genetic material.
