Orcas Reconsidered

Although all the planet’s killer whales are currently considered a single species (Orcinus orca), some of the world’s leading experts are proposing to split them into three species. Photo by imagebroker.com/Alamy Stock Photo

Hakai is the go-to magazine for marine stories, and we hope to see more work of Craig Welch, the science journalist who wrote the article below, in the future:

Meet the Killer Whales You Thought You Knew

The iconic marine mammals may not belong to one species but several. Surprise!

John Ford still recalls the first time he heard them. He’d been puttering around the Deserters Group archipelago, a smattering of spruce- and cedar-choked islands in Queen Charlotte Strait, between Vancouver Island and mainland British Columbia. He was piloting a small skiff and trailing a squad of six killer whales. Ford, then a graduate student, had been enamored with cetacean sounds since listening to belugas chirp while he worked part-time at the Vancouver Aquarium as a teenager. Now here he was, on August 12, 1980, tracking the underwater conversations of wild killer whales through a borrowed hydrophone. Continue reading

Dutch Water Knowhow Is Respectable

We respect the Dutch for their respect of nature, particularly their respect for the power of water and their longstanding determination to harmonize our life with it. This profile extends our respect:

A Dutch Architect’s Vision of Cities That Float on Water

What if building on the water could be safer and sturdier than building on flood-prone land?

In a corner of the Rijksmuseum hangs a seventeenth-century cityscape by the Dutch Golden Age painter Gerrit Berckheyde, “View of the Golden Bend in the Herengracht,” which depicts the construction of Baroque mansions along one of Amsterdam’s main canals. Handsome double-wide brick buildings line the Herengracht’s banks, their corniced façades reflected on the water’s surface. Interspersed among the new homes are spaces, like gaps in a young child’s smile, where vacant lots have yet to be developed.

For the Dutch architect Koen Olthuis, the painting serves as a reminder that much of his country has been built on top of the water. The Netherlands (whose name means “low countries”) lies in a delta where three major rivers—the Rhine, the Meuse, and the Scheldt—meet the open expanse of the North Sea. More than a quarter of the country sits below sea level. Over hundreds of years, the Dutch have struggled to manage their sodden patchwork of land. Continue reading

Ed Yong With Binoculars

Ed Yong has graced our pages for a decade and still finds new ways to communicate the wonders of nature:

When I Became a Birder, Almost Everything Else Fell Into Place

Last September, I drove to a protected wetland near my home in Oakland, Calif., walked to the end of a pier and started looking at birds. Throughout the summer, I had been breaking in my first pair of binoculars, a Sibley field guide and the Merlin song-identification app, but always while hiking or walking the dog. On that pier, for the first time, I had gone somewhere solely to watch birds. Continue reading

An Unappreciated Creature

A macro image of a Costa Rican mosquito, Psorophora cilipes.

Living in, or even just visiting Costa Rica, inspires appreciation, and respect, for nature. But one creature defies this spirit:

Entomologist says there is much scientists don’t know about habitats, habits, impacts on their environments

A blood-sucking nuisance, mosquitoes are responsible for spreading diseases to hundreds of millions of people every year. True?

Yes, says entomologist Lawrence Reeves, but it’s also true that mosquitoes primarily feed on plant sugars, not blood. Only female mosquitoes consume blood, and only when they need it to complete their reproductive cycle. Also, it is possible some may serve as pollinators like bees, allowing plants to produce fruit, seeds, and more young plants. Continue reading

Breadfruit More Fully Appreciated

Our thanks to Zoë Schlanger for this corrective. Breadfruit has appeared more than once in our pages, but never with appreciation like this:

Too Few Americans Are Eating a Remarkable Fruit

Breadfruit is a staple in tropical places—and climate change is pushing its range north.

Someplace in the lush backroads of San Sebastián, in western Puerto Rico, my friend Carina pulled the car over. At a crest in the road stood a breadfruit tree, full of basketball-size, lime-green fruits, knobbled and prehistoric, like a dinosaur egg covered in ostrich leather. Continue reading

Ants & Us

Ant geopolitics

Over the past four centuries quadrillions of ants have created a strange and turbulent global society that shadows our own

It is a familiar story: a small group of animals living in a wooded grassland begin, against all odds, to populate Earth. At first, they occupy a specific ecological place in the landscape, kept in check by other species. Then something changes. The animals find a way to travel to new places. They learn to cope with unpredictability. They adapt to new kinds of food and shelter. They are clever. And they are aggressive. Continue reading

Children, Phones & Futures

Photographs by Maggie Shannon

It has been our belief since starting that getting outdoors is a very good preventative medicine, but maybe that was too simple a focus. Phones have disrupted life, especially for our young ones, more than we appreciated. Our thanks to Jonathan Haidt and The Atlantic for this (podcast discussion of the research here):

The environment in which kids grow up today is hostile to human development.

Something went suddenly and horribly wrong for adolescents in the early 2010s. Continue reading

Addiction To Longevity

Like many Italian aging researchers, Dr. Longo thinks Italy doesn’t invest enough in research. “Italy’s got such incredible history and a wealth of information about aging,” he said. “But spends virtually nothing.” Alessandro Grassani for The New York Times

Faux fasting is new to us, but thinking about diet is not. Our thanks to Jason Horowitz for another story from Italy:

To Live Past 100, Mangia a Lot Less: Italian Expert’s Ideas on Aging

Valter Longo, who wants to live to a healthy 120 or 130, sees the key to longevity in diet — legumes and fish — and faux fasting.

Most members of the band subscribed to a live-fast-die-young lifestyle. But as they partook in the drinking and drugging endemic to the 1990s grunge scene after shows at the Whisky a Go Go, Roxy and other West Coast clubs, the band’s guitarist, Valter Longo, a nutrition-obsessed Italian Ph.D. student, wrestled with a lifelong addiction to longevity.

Where Does Captured Carbon Go?

The Heirloom Carbon direct air capture plant in Tracy, California, which opened last November. HEIRLOOM CARBON

For keeping an eye on the captured carbon trail, thanks to Nicola Jones:

As Carbon Air Capture Ramps Up, Major Hurdles Remain

Aided by tax breaks and carbon credits, scores of plants are being developed or are now operating that remove CO2 from the air. Such facilities are considered necessary to limit global warming, but critics have questions about the high costs and where the captured carbon will go.

Texas is by far the top emitter of greenhouse gases in the United States: The oil-rich state releases twice as much carbon dioxide as the runner-up state, California, and as much as the entire country of Germany. Continue reading
