Sonia Shah, a science journalist and author of “The Next Great Migration: The Beauty and Terror of Life on the Move,” has provided a great summary of recent developments on the study of animal migration:

Animal Planet

An ambitious new system will track scores of species from space — shedding light, scientists hope, on the lingering mysteries of animal movement.

‘‘I’m going to do a set of coos,” Calandra Stanley whispered into the radio. The Georgetown ornithologist and her team had been hunting cuckoos, in an oak-and-hickory forest on the edge of a Southern Illinois cornfield, for weeks. Droplets of yesterday’s rain slid off the leaves above to those below in a steady drip. In the distance, bullfrogs croaked from a shallow lake, where locals go ice fishing in winter.

Anne Hidalgo has been featured in our pages several times for greening her city, and now this:

Paris — Mayor Anne Hidalgo has confirmed that ambitious plans to transform Paris’ Champs-Élysées, the iconic avenue in the heart of the French capital, are still on the table. Her initiative will see the avenue with fewer car lanes, more room for pedestrians and much more greenery.

Often dubbed “the most beautiful avenue in the world,” the Champs-Élysées has gone three decades without a major overhaul, and many Parisians believe it looks tired and a lot less sophisticated than it used to. Continue reading →

Where Do Migrants Go in Winter? New Models Provide Exquisite Detail

By Gustave Axelson; Illustrations by Jillian Ditner

Part of the magic of migratory birds is their annual disappearing act—one autumn day there might be an oriole in a treetop, and the next day it’s gone, not to be seen again until spring.

Back in the 17th century, scientists had lots of ideas about where birds go during winter in the Northern Hemisphere, including one theory that they migrate to the moon. Today we know Neotropical migratory birds are intercontinental travelers, chasing summer as they leave the North for the warmer weather and longer days of the New World tropics. Continue reading →

New gene-editing technology could be used to save species from extinction—or to eliminate them.

Odin, in Norse mythology, is an extremely powerful god who’s also a trickster. He has only one eye, having sacrificed the other for wisdom. Among his many talents, he can wake the dead, calm storms, cure the sick, and blind his enemies. Not infrequently, he transforms himself into an animal; as a snake, he acquires the gift of poetry, which he transfers to people, inadvertently.

The Odin, in Oakland, California, is a company that sells genetic-engineering kits. The company’s founder, Josiah Zayner, sports a side-swept undercut, multiple piercings, and a tattoo that urges: “Create Something Beautiful.” He holds a Ph.D. in biophysics and is a well-known provocateur.

Aerial Views Of Progress

Thanks to Yale e360 for a bit of visual perspective on human interventions–efforts to improve landscapes and energy-harnessing:

Overview: Transforming Land and Sea for a More Sustainable World

Aerial photos often document the destruction of the natural world. But these striking satellite images show how countries are beginning to respond to the global environmental crisis by restoring ecosystems, expanding renewable energy, and building climate resiliency infrastructure.

As the global population nears 8 billion, the human footprint can be seen in almost every corner of the Earth. Logging roads cut deep into the Amazon rainforest. Plastics swirl in remote parts of the ocean. The world’s largest gold mine is carved out of the mountains of Indonesia.

Satellite and aerial images have captured much of this destruction, often in startling and unsettling images. But a new collection of photos offers a different view: Images of places where efforts are underway to slow or even reverse the damage we have done to the planet — Continue reading →

Reprieve For Alaskan Nature

Caribou graze on the coastal plain of the Arctic National Wildlife Refuge. The Trump administration has held the first oil lease sale in the refuge. U.S. Fish and Wildlife Service

Thanks to all those who protested the lease sale in the first place, and to National Public Radio (USA) for providing the welcome news that the protests had their intended effect:

Major Oil Companies Take A Pass On Controversial Lease Sale In Arctic Refuge

One of the Trump administration’s biggest environmental rollbacks suffered a stunning setback Wednesday, as a decades-long push to drill for oil in Alaska’s Arctic National Wildlife Refuge ended with a lease sale that attracted just three bidders — one of which was the state of Alaska itself.

Alaska’s state-owned economic development corporation was the only bidder on nine of the parcels offered for lease in the northernmost swath of the refuge, known as the coastal plain. Two small companies also each picked up a single parcel.

Half of the offered leases drew no bids at all. Continue reading →
