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

Testing Animal Intelligence

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

Vertical farming, urban farming, innovations we have seen mostly from industrialized places, are important in developing countries as well:

Rooftop farming: why vertical gardening is blooming in Kampala

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

Protecting Nature & Defying The Odds

Thanks to Shannon Sims for this story of a refuge defying the odds:

A Rwandan Game Park Defying the Odds

Despite modest tourism numbers, Akagera National Park is a success story in the making, particularly considering that, like its host country, it survived catastrophe.

The road through Akagera National Park in eastern Rwanda was blocked. Two giraffes had positioned themselves smack in the middle of the dirt road and were rubbing their necks together. In the car, with a driver and a guide, my cell service was long gone; there was nothing to do but sit back, relax and enjoy the show.

Right around this time of year, to the east of Rwanda’s borders, in Tanzania and Kenya, big packs of tourists are stumbling over each other to get the perfect photo of a scene like this. They’re driving through protected areas like Serengeti National Park and the Maasai Mara National Reserve in caravans of Land Rovers, each packed so tightly that peoples’ binocular straps get tangled up. It makes sense: the animal migrations that occur in this part of the world these months are rightly considered by many to be the greatest natural show on earth. Continue reading

Be Aware, Big Boom & Beware

csm_TOC_Computer_Renderings_Profileview_2942c52c93.jpg

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:

TOC_map-gyres-02

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

Concentration_microplasticsOur 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

One More Reason To Eliminate As Much Plastic As You Can From Your Daily Routines

Thanks to Karen Weintraub for this stark reminder, one of countless examples, of why so many places, and some big companies and many individuals are doing their best to get plastic out of daily routines:

Just a Few Pieces of Plastic Can Kill Sea Turtles

A new study shows that especially for young turtles, ingesting just a little more than a dozen pieces of plastic in the ocean can be lethal.

14SCI-SEATURTLES2-jumbo.jpg

All over the world, sea turtles are swallowing bits of plastic floating in the ocean, mistaking them for tasty jellyfish, or just unable to avoid the debris that surrounds them.

Now, a new study out of Australia is trying to catalog the damage.

While some sea turtles have been found to have swallowed hundreds of bits of plastic, just 14 pieces significantly increases their risk of death, according to the study, published Thursday in Scientific Reports.

Young sea turtles are most vulnerable, the study found, because they drift with currents where the floating debris also accumulate, and because they are less choosy than adults about what they will eat.

Worldwide, more than half of all sea turtles from all seven species have eaten plastic debris, estimated Britta Denise Hardesty, the paper’s senior author and a principal research scientist with the Commonwealth Scientific and Industrial Research Organization in Tasmania. “It doesn’t matter where you are, you will find plastic,” she said.

Libraries As Palaces For The People

9781524761165We 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 Klinenbergprofessor 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.

Economics, Prodigy & A Better Future

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:

Amazon’s Antitrust Antagonist Has a Breakthrough Idea

With a single scholarly article, Lina Khan, 29, has reframed decades of monopoly law.

09Khan1.print-superJumbo-v2.jpg

In early 2017, when she was an unknown law student, Lina Khan published “Amazon’s Antitrust Paradox” in the Yale Law Journal. Credit Brandon Thibodeaux for The New York Times

The dead books are on the top floor of Southern Methodist University’s law library.

“Antitrust Dilemma.” “The Antitrust Impulse.” “Antitrust in an Expanding Economy.” Shelf after shelf of volumes ignored for decades. There are a dozen fat tomes with transcripts of the congressional hearings on monopoly power in 1949, when the world was in ruins and the Soviets on the march. Lawmakers believed economic concentration would make America more vulnerable.

At the end of the antitrust stacks is a table near the window. “This is my command post,” said Lina Khan.

It’s nothing, really. A few books are piled up haphazardly next to a bottle with water and another with tea. Ms. Khan was in Dallas quite a bit over the last year, refining an argument about monopoly power that takes aim at one of the most admired, secretive and feared companies of our era: Amazon.

The retailer overwhelmingly dominates online commerce, employs more than half a million people and powers much of the internet itself through its cloud computing division. On Tuesday, it briefly became the second company to be worth a trillion dollars. Continue reading

Riverford, A Model Of Organic Farming In The UK

We first heard the name of the farmer on a favored music-oriented podcast, and then the name of his farm. After listening to his story, and his musical tastes, we had to learn more:

guy-singh-watson-4.jpgSelf-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

Omnivore’s Dilemma In A Shark Species

Thanks to Veronique Greenwood for this:

The Omnivorous Sharks That Eat Grass

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
