The House Over Hades

In June of 1996, Kathi Loughlin’s phone rang at work. It was her child’s nanny, and she was frantic. “Something is going on here, you need to come home,” the nanny said, a note of panic in her voice. Loughlin had trouble understanding what exactly

The Scientists Who Created America’s War Gases

SONORA, Calif. — In a back room of L. Philip Reiss’ condominium, the retired chemical engineer has covered the walls and filled his drawers with mementos of a long life in science. In one corner, he’s hung keepsakes from years volunteering with a Boy Scout

Methane: Arctic Promise and Peril

Consigned to my bunk all night by gut-wrenching seas, I wistfully thought back to terra firma on mainland Norway a few days earlier. Before boarding the University of Tromsø’s research ship, R/V Helmer Hanssen,

BOOM: North America’s Explosive Oil-by-Rail Problem

U.S. regulators knew they had to act fast. A train hauling 2 million gallons of crude oil from North Dakota had exploded in the Canadian town of Lac-Megantic, killing 47 people. Now they had to assure Americans a similar disaster wouldn’t happen south of the border, where the U.S. oil boom is sending

Meltdown: Vanishing Polar Ice

“What you are looking at,” lamented marine biologist Haakon Hop of the Norwegian Polar Institute, “is the melting of the Arctic Ocean.”

Nearing 82 degrees north latitude aboard the research ship RV Lance in late July 2013, we were just 500 miles shy of the North Pole.

The Scientist Who Explored the Skies

MT. PALOMAR – Visiting the Palomar observatory in the forested mountains northeast of San Diego is a bit like finding oneself at the foot of one of the great pyramids of Egypt. The scale is so intimidating, so outsized compared to its surroundings, that you

Americans Are Working So Hard, It’s Actually Killing People

Jessica Wheeler works the night shift as an oncology nurse at Wilkes-Barre General Hospital in northeastern Pennsylvania—but her patients are usually wide awake. “When they have a new cancer diagnosis or they’re going to have a biopsy in the morning, they don’t sleep,”

Which Species Will Live?

The ashy storm-petrel, a tiny, dark-gray seabird, nests on 11 rocky, isolated islands in the Pacific Ocean off the coasts of California and Mexico. Weighing little more than a hefty greeting card and forced to contend with invasive rats, mice and cats, aggressive seagulls, oil spills and sea-level rise, it faces an outsize fight for survival.

Centuries after the Black Death, Plague Still Kills

ARUA, Uganda — Isaac Baniyo stumbled through his final exam in English last November as a pounding headache and chest pain made it difficult to focus. The teenager’s parents sent him on foot to a drug shop not far from their grass-roofed hut in the

The WHO vs. the Tea Doctor

ENTEBBE, Uganda—It’s a little after 9 a.m. on the Wagagai Flower Farm, and Robert Watsusi pedals a bicycle laden with two 3-gallon jugs of a hot, bitter black tea. As he rounds a corner, workers emerge from football field–size growing houses to imbibe their weekly dose of the elixir they say keeps them free from malaria.

Climate adaptation: Survival of the flexible

Up in the foothills of the Rockies last summer, researchers from Colorado State University in Fort Collins fanned out along the banks of a stream. Some took the water’s temperature and measured its speed and chemistry. Others waded in to catch insects using flat-bottomed nets.

Should we Dilute Genes to Save a Species?

West of Pahrump, Nevada, in a corner of the Mojave Desert a couple thousand feet above Death Valley, a warm aquifer provides a home for one of the world’s rarest animals. It’s a tiny silvery-blue fish, smaller than your pinkie toe, and in the past 50 years it has survived real-estate speculators,

A Rise in Fungal Diseases is Taking A Growing Toll on Wildlife

On the southeastern outskirts of Washington, D.C., inside the Smithsonian Institution’s cavernous Museum Support Center, one can see some frogs that no longer exist. Alcohol-filled glass jars hold preserved specimens of Incilius periglenes, the Monte Verde golden toad;

Frozen Sperm Offer a Lifeline for Coral

COCONUT ISLAND, Hawaii — Just before sunset, on the campus of the Hawaii Institute of Marine Biology, Mary Hagedorn waited for her mushroom corals to spawn.

As corals go, Fungia is fairly reliable, usually releasing its sperm and eggs two days after the full moon.

Good Germs Gone Bad

To work in Abigail Salyers’ laboratory at the University of Illinois, is to play matchmaker to some unlikely couples. Standing at her laboratory bench, PhD student Kaja Malanowska lifts the cover from a petri dish to pick up a half a billion or so Escherichia

Aquaculture Moves Offshore

The white spires of the Algonquin Hotel towered above the coastal town of St. Andrews, New Brunswick, the center of aquaculture development in Canada’s maritime provinces. Government officials and aquaculture industry representatives from Canada, Norway, and the U.S. met at the Algonquin to discuss fish
