Life after cancer treatment is different. So are the health needs.
Nearly 10 years after Kara Kenan of North Carolina finished treatment for advanced breast cancer, her routine bloodwork revealed an increased level of an enzyme called alkaline phosphatase. Kenan’s primary care doctor didn’t think that was important, so he ordered no further tests. But Kenan, who directs marketing for the advocacy group Cancer Nation, knew

Meet the mysterious electrides | Knowable Magazine
For close to a century, geoscientists have pondered a mystery: Where did Earth’s lighter elements go? Compared to amounts in the Sun and in some meteorites, Earth has less hydrogen, carbon, nitrogen and sulfur, as well as noble gases like helium — in some cases, more than 99 percent less. Some of the disparity is

How scientists recreate historical scents
We often learn about the past visually — through oil paintings and sepia photographs, books and buildings, artifacts displayed behind glass. And sometimes we get to touch historical objects or listen to recordings. But rarely do we use our sense of smell — our oldest, most primal way of learning about the environment — to

The case against the Zanclean megaflood refilling the Mediterranean
On October 6, 1970, the deep-sea drilling vessel Glomar Challenger returned to port in Lisbon, Portugal, bearing a cargo that would revise history. During its 54-day voyage, the Challenger had punched 28 holes into the bottom of the Mediterranean Sea. The recovered cores pointed toward a startling conclusion: About 6 million years ago, the sea
