Alan Taylor, who compiles and edits the news photo blog “In Focus” for the Atlantic, shares 21 spectacular images with captions that help even a lay person understand better the science of climate change:
Earlier this year, Lucas Jackson, a photographer with Reuters, joined a team of scientists affiliated with a NASA project named Oceans Melting Greenland (OMG) and traveled with it to the Greenland ice sheet and fjords. Jackson photographed the researchers as they set up their scientific equipment and took readings to help understand the ongoing impact of the melting glaciers and map out what to expect in the future. Jackson says: “For both journalists and scientists, climate change is difficult to document. It most often happens imperceptibly—a tenth of a degree increase in temperature, a few less inches of rain, a slowly melting ice sheet.” Continue reading
Thanks to James Gorman for the latest examination of animal intelligence:
Chalk up another achievement for parrots, with an odd twist that raises questions about whether the experimenters or the birds know best.
Anastasia Krasheninnikova and colleagues at the Max Planck Institute for Ornithology in Germany tested four species of parrots in an experiment that required trading tokens for food and recently reported their findings in the journal Scientific Reports.
Would the birds resist an immediate reward to trade for something better? Many species have shown the ability to hold off on an immediate treat — like a dry corn kernel — for something tastier later on, like a bit of walnut. Continue reading
Ugandans are finding creative solutions to the growing challenges of urbanisation
When Martin Agaba realised his urban farm had run out of space, he decided the solution was not to expand outwards but upwards.
“We realised we had to use the roof,” he says. Of all the innovations that have galvanised people in his district in the Ugandan capital Kampala to grow their own food, these vertical box plantations remain his favourite.
Kwagala farm, located on half an acre of land, is the brainchild of Diana Nambatya, a professor in public health, who began growing vegetables to save money on food in 2010.
After receiving two cows as a dowry, she decided to use their dung to generate biogas for her home. Her burgeoning urban farm soon attracted the attention of the neighbours, and in 2012 she started training women at a small demonstration centre. Continue reading
Thanks to Shannon Sims for this story of a refuge defying the odds:
Thanks to Christina Caron for this story that raises important questions about an awesome-sounding technology. Best to first read from The Ocean Cleanup website, and if you have been following the stories we pay attention to you will understand how we might get hooked on the idea:
Ocean garbage patches are vast and dispersed
Ocean currents concentrate plastic in five areas in the world: the subtropical gyres, also known as the world’s “ocean garbage patches”. Once in these patches, the plastic will not go away by itself. The challenge of cleaning up the gyres is the plastic pollution spreads across millions of square kilometers and travels in all directions. Covering this area using vessels and nets would take thousands of years and cost billions of dollars to complete. How can we use these ocean currents to our advantage?
THE IMPACT OF CLEANUP
Our models indicate that a full-scale system roll-out could clean up 50% of the Great Pacific Garbage Patch in 5 years.
Research shows the majority of plastic by mass is currently in the larger debris. By removing the plastic while most of it is still large, we prevent it from breaking down into dangerous microplastics.
Combining the cleanup with source reduction on land paves the road towards a plastic free ocean by 2050.
The story in the New York Times raises important questions, not least of which is that Peter Thiel is involved:
…But the ocean can be unpredictable, and simulation models are no guarantee of future performance.
“There’s worry that you can’t remove the plastic without removing marine life at the same time,” said George Leonard, chief scientist at the Ocean Conservancy. “We know from the fishing industry if you put any sort of structure in the open ocean, it acts as a fish-aggregating device.” Continue reading

We have had more stories in seven years about libraries, and librarians and books than most other topics, so we are pleased to pass along this reference to a book about libraries (among other essential elements of social infrastructure). In 20 minutes on this podcast the ideas in this book are discussed by the author:
Eric Klinenberg, professor of sociology and director of the Institute for Public Knowledge at New York University and the author of Palaces for the People: How Social Infrastructure Can Help Fight Inequality, Polarization, and the Decline of Civic Life (Crown, 2018), argues that the future of democracy lies in shared spaces, like libraries and parks.
I have resisted placing orders through Amazon about as steadfastly as humanly possible in the economic and cultural life Amazon has now taken such a prodigious role in. I have had plenty of hints of what the key points are in the growing debate about the company and why to resist it. Thanks to this excellent profile by David Streitfeld, I have a better understanding of why this is so important, and thanks to Lina Khan I have faith that the only way to counter prodigious power is with the power of prodigy:
Self-confessed veg nerd, Guy Singh-Watson has over the last 30 years taken Riverford from one man and a wheelbarrow delivering homegrown organic veg to friends, to a national veg box scheme delivering to around 50,000 customers a week.
Guy is an inspirational, passionate, opinionated and admired figure in the world of organic farming, who still spends more time in the fields than in the boardroom. Continue reading

Diminutive bonnethead sharks are the first omnivorous sharks known to science, which could change our understanding of what some sharks eat.
Sharks are not known for their taste for greenery. But at least one species of shark enjoys a salad of sea grass as well as the prey it hunts.
The bonnethead shark, a diminutive species that reaches up to 3 feet in length, lives in the shallow sea grass meadows off both coasts of the Americas. It eats small squid and crustaceans ferreted from the swaying underwater fronds. But, researchers who have carefully monitored everything going in and out of captive bonnetheads say in a study published in Proceedings of the Royal Society B that they also eat large quantities of seagrass. The grass isn’t just passing inertly through the sharks’ guts. They extract nutrition from it just as they do from the meaty portion of their diet. These sharks must, therefore, be reclassified as omnivores — the first omnivorous sharks known to science. Continue reading
