Solar power is always on our radar, but we understand that storing the electricity from photovoltaics can be an issue. Today we are learning about a new solar technology for the first time, even though it revolves around something that we benefit from every day: the sun’s heat. Umair Irfan reports for Scientific American‘s ClimateWire section on this interesting idea being researched in Europe:

COLOGNE, Germany—At Germany’s aerospace agency, the next frontier is capturing the sun here on Earth and keeping it on tap.

In a 4-year-old glass and steel building near the Cologne-Bonn Airport, researchers at the German Aerospace Center (DLR), Germany’s equivalent of NASA, are working on new ways to produce more heat than light in order to smooth over intermittency, one of the biggest drawbacks of solar power on the grid.

A Just So Story by DNA

/ Organikos / Leave a comment

A few years ago we shared a story similar to the one below, where Kipling’s Just So Stories were linked with reporting on modern evolutionary biology; a year before that, at the beginning of this blog’s start in India, we discussed Kipling’s ties to that country and its wildlife. From the New Yorker‘s Elements section comes the story “How the Giraffe Got Its Neck,” by Anthony Lydgate:

It’s difficult to know what to make of the giraffe. It shuffles like a camel (right legs forward, then left legs) but runs like a rabbit (hind legs forward, then front legs). Its distinctive aroma repulses many ticks but enchants certain people. It bellows, hisses, and moans in the wild, and in captivity it hums in the dark. It naps with its head aloft but sleeps like a swan, with its head on its haunches. Had Aristotle ever seen a giraffe, he might have said that it was the product of an interspecies dalliance at the watering hole, which he thought of as a kind of zoological swingers’ club—a place where “bastard animals are born to heterogeneous pairs.”

Beetles, apart from being the most numerous type of insect in the world, comprise the largest group of animals in general, with somewhere between three- and four-hundred thousand species described; and that doesn’t even count the presumably undiscovered ones hiding out in some unexplored corner somewhere. We’ve covered dung beetles before, but also mycokleptic species, and now we’re learning about a very important carrion beetle in North America known as the American burying beetle from Ted Williams at The Nature Conservancy’s Cool Green Science blog:

The shiny black, orange-spotted adults can approach two inches in length. Offspring beg both parents for food, inducing regurgitation by stroking their jaws like wolf pups. They’re federally endangered American burying beetles, largest of the 31 species of North American carrion beetles.

Riding on the adults like oxpeckers are orange mites that keep them and their larval food supply free of fly eggs and microbes.

Waste Not, Want Not

Indian weddings (and other big parties) serve a lot of food — and have a lot of leftovers. Now there’s a plan in Mumbai to share the surplus with those who are hungry.
Mahesh Kumar A./AP

Living in India provides daily examples of life’s major contradictions: silence and chaos, simplicity and grandeur, lack and excess… Traditional Indian weddings illustrate the examples of abundance – even the most modest of weddings will represent some version of the the proverbial “groaning board” – be it traditional banana-leaf thali of south India or an elaborate multi-course dinner in towering tents. Whenever food is prepared for a crowd there’s potential for waste, even in the so-called “developed world”.

The beauty of this inspiring story is how it taps into Mumbai’s dabbawalla system, taking advantage of the extraordinary logistics of a food distribution system that has functioned well for decades. (If you’ve never seen Ritesh Batra’s beautiful film The Lunchbox, run and find it now…)

India has 194.6 million undernourished people — that’s more than half the world total.It’s what people mean when they talk about “food insecurity:” the economic and social condition of limited or unpredictable access to adequate food.

But in a study published in the August 2015 issue of the journal Lancet, researchers found that India also has 46 million obese citizens.

The dabbawallas — Mumbai’s lunch delivery collective — have stepped in with an initiative they’re calling the Roti Bank. Their aim is to connect the have-nots with the have-too-muchs.

“We deal with food every day, so we’re ideally placed to fix this,” says Dashrath Kedare, a co-founder of the Roti Bank and a leader of one of the dabbawalla unions. Continue reading →

We are happy any time this novelist takes time from his main craft to devote time to what seems to be his main personal passion, which might be identified as birding, or else more broadly speaking the environment in which birds thrive (or not). From this week’s New Yorker, another journey far away, southward, by Jonathan Franzen with an eye to environmentalist perspective:

The End of the End of the World

An uncle’s legacy and a journey to Antarctica.

BY

Two years ago, a lawyer in Indiana sent me a check for seventy-eight thousand dollars. The money was from my uncle Walt, who had died six months earlier. I hadn’t been expecting any money from Walt, still less counting on it. So I thought I should earmark my inheritance for something special, to honor Walt’s memory.

It happened that my longtime girlfriend, a native Californian, had promised to join me on a big vacation. She’d been feeling grateful to me for understanding why she had to return full time to Santa Cruz and look after her mother, who was ninety-four and losing her short-term memory. She’d said to me, impulsively, “I will take a trip with you anywhere in the world you’ve always wanted to go.” To this I’d replied, for reasons I’m at a loss to reconstruct, “Antarctica?” Her eyes widened in a way that I should have paid closer attention to. But a promise was a promise. Continue reading →

“Certified Transitional” Ingredients

We put a lot of stock in organic farming, as well as eating and drinking. If companies do it right, sourcing organically can make a difference. So it’s uplifting to read that two companies we support by buying their delicious products, Clif Bar and Kashi, are making an effort to bolster the organic ingredient supply chain by leading a new category for crops produced by farmers who are in the three-year process of switching from conventional agriculture to an organic label; it’s called “Certified Transitional.” Lauren Hepler reports for GreenBiz:

Inside an airy, post-industrial space situated on the East side of the San Francisco Bay, several brightly colored mountain bikes and the sail of a kite surfing set hang from a lofted ceiling above some 350 employees sprawled across the 150,000-square-foot headquarters of Clif Bar.

Outside, a small organic gardening plot has been set up next to the free daycare center for the children of employees at the famously outdoorsy food company.

“We start ’em young,” jokes Dean Mayer, Clif Bar’s communications manager.

Hydropeaking Dams = Fewer Insects

/ Organikos / Leave a comment

Although we’ve heard of dams causing environmental and community problems before, we’ve also seen how they can be beneficial to society, and it’s clear that they’re a double-edged sword. Most recently on the topic, we learned that with proper planning and design, hydropower can be less of an enemy to conservation. Now, research highlighted in Conservation Magazine displays the possibility of helping native river-reliant insect populations by adjusting how dams “hydropeak,” or change river flow to compensate for electricity demand. Sarah DeWeerdt reports:

Scientists know that hydropower dams often decrease the abundance and diversity of aquatic insects downstream. But until now it wasn’t clear why—after all, dams cause a range of environmental stressors such as alterations in water flow, temperature, and sedimentation.

A massive new study led by the U.S. Geological Survey lays much of the blame on hydropeaking, the practice of varying river flows below a dam depending on electricity demand. Because of hydropeaking, the amount of water released from a dam can vary by as much as ten-fold throughout the day, creating an artificial intertidal zone that propagates for hundreds of kilometers downstream.

Antler Awareness

In Oregon, elk populations have grown so large that they are threatening a key forest tree species: the aspen, whose leaves turn a vivid yellow in the fall and create amazing landscape scenes, particularly in the western United States. To raise awareness of the issue and also generate funds for local children, people near The Nature Conservancy’s Zumwalt Prairie Preserve go out and search for elk antlers that have been shed each spring, then sell the antlers. Matt Miller writes for the TNC blog:

As our vehicles roll to a stop along the muddy track, a postcard-perfect scene stretches before us. Rolling prairie dotted with beautiful wildflowers, with towering snow-capped peaks in the background. But the kids around me don’t notice any of it.

“Antler!” one of them cries, and the group is off, running across the rolling hills. A youngster is soon hoisting an impressive elk antler over his head. His friends look on with admiration, but soon another antler is spotted, and another.

And speaking of NPR, one of the podcasts that originates on its New York City affiliate WNYC–Radio Lab, which was featured in some of our earliest posts–this episode featuring another beetle may have been the greatest of all time.

Dung Beetles Navigate Poop-Pile Getaways Using Celestial ‘Snapshots’

It’s not easy being a dung beetle.

Besides the obvious fact that they eat, well, dung, the act of just getting a meal is an involved process.

In the most elaborate carry-out scenario, the dung beetles must first stake claim to their piece of poop at the main dung pile, then shape it into a sphere for easy transport, fend off other dung beetles trying to steal it, and then — using the stars to navigate — determine the fastest way to roll their prize away to a safe spot for consumption.

Human – Pachyderm – Apium Collaboration

/ Organikos / Leave a comment

Innovation takes many forms. It’s especially satisfying when that innovation works with nature instead of against her. Examples of creative collaboration to solve environmental issues, be they unusual agricultural pest control or ways to avoid human/wildlife conflict such as this Elephant and Bee project are happy news indeed.

Some of our team live in Kerala, India – and know from personal experience the intelligence, and perseverance of elephants, when confronted with an obstacle to plants or trees they crave. This beehive fence concept is incredibly clever, taking advantage of the elephants’ natural fear of bees to keep them safe from potentially deadly conflict.

“I congratulate Dr. King as the winner of this important award. Her research underlines how working with, rather than against, nature can provide humanity with many of the solutions to the challenges countries and communities face. Continue reading →

Science Cannot Serve Two Masters

Go to the dictionary, or notes from a science course you might have taken, to be reminded of the definition of how this body of knowledge operates, and the importance of avoiding bias is evident. When it relates to the survival or collapse of species, avoiding bias seems even more important than the definition implies. Science serves the interest of objective, verifiable truth; not economic or political interests (thanks to National Public Radio, USA):

Climate Change Is Shrinking Earth’s Far-Flying Birds

In which the red knot is the canary, and the planet is the coalmine.

ED YONG

Every year, flocks of red knots criss-cross the globe. In the summer, these shorebirds breed in the Arctic circle, making the most of the exposed vegetation and constant daylight. Then, anticipating the returning ice and continuous night, they fly to the opposite end of the world. Different populations have their own itineraries, but all are epically long: Alaska to Venezuela; Canada to Patagonia; Siberia to Australia.

These migratory marathons mean that the red knot’s fate in one continent can be decided by conditions half a world away. And that makes it a global indicator, a sentinel for a changing world. It is the proverbial canary in the coalmine, except the mine is the planet.

And the canary is shrinking. Continue reading →

Once again, Science Friday has come through with a cool article about an interesting subject. It contains excerpts from a new book containing images from camera traps, which are good research tools for animals that try to avoid humans. We’ve featured the devices a lot as a result, and now we get to continue doing so. Julie Leibach reports:

A new book of unabashed selfies has been released, but it reveals neither hide nor hair of a Kardashian. There is, however, plenty of hide and hair. Candid Creatures: How Camera Traps Reveal the Mysteries of Nature, by zoologist Roland Kays, is an album of wildlife photos captured with camera traps—devices that researchers install in the field to record members of the animal kingdom as they lope, scamper, or climb about their business. Kays’ book is also a rich summary of the insights that scientists have gained from using these tools.

Charcoal has often been used by artists as a tool for sketching, but now this:

Floating Charcoal Sculptures Explore The Complex Relationship Between Man And Nature

Priscilla Frank
Arts Writer, The Huffington Post

Charcoal is a natural substance derived from the geological process of burning trees. The light black residue that remains, though created by nature, has a distinct architecture to its rough sides and sharp edges, reminiscent of the shapes made, consciously, by man.

Korean artist Seon Ghi Bahk uses this unorthodox artistic material to explore the complex and interwoven relationship between nature and human civilization. While Western culture has the tendency to view our natural surroundings as either a tool of human civilization or a pleasant backdrop for our daily lives, Bahk paints, or rather sculpts, a more nuanced picture.

Thanks to the Harvard Gazette for this interview with William Clark:

Pursuing sustainability

A Q&A on connecting science and practice, balancing conservation with use

By Amanda Pearson, Weatherhead Center Communications

United Nations Secretary-General Ban Ki-moon on Friday will welcome 130 heads of state who have pledged to sign the Paris Agreement, the global agreement on managing climate change. For William Clark, Harvey Brooks Professor of International Science, Public Policy, and Human Development at Harvard Kennedy School (HKS), sustainability is a global imperative and a scientific challenge like no other.

Clark sees the Paris Agreement as just one step, though an important one, in this urgent pursuit, as officials wrestle with how to meet the needs of a growing human population without jeopardizing the planet for future generations. He and co-authors Pam Matson of Stanford University and Krister Andersson of the University of Colorado at Boulder tackle that issue in a new book, “Pursuing Sustainability: A Guide to the Science and Practice.” By looking at sustainability as a means of alleviating poverty and enhancing well-being, the book highlights the complex dynamics of social-environmental systems, and suggests how successful strategies can be shaped through collaborations among researchers and practitioners.

Clark, who trained as an ecologist, said that while exhausting Earth’s natural resources would jeopardize future generations, sustainability could counter that. The goal is to find a healthy equilibrium between human adaptation and natural evolution. Clark, the co-director of the Sustainability Science Program at HKS, spoke with the Weatherhead Center for International Affairs about building a more sustainable future. Continue reading →

We are concerned, and therefore generally against, GMOs up to now. But we are not 100% sure and so welcome new information when it is available. The University of Washington’s magazine, Conservation, is back in full awesomeness as a public service:

Despite the controversy surrounding genetically modified crops, they can be an important tool for developing disease-resistant crops that can eliminate the use of pesticides and reduce crop losses. In a trio of papers published recently in Nature Biotechnology, researchers documented how new, faster methods of isolating genes—and looking in some unexpected places—led them to identify, clone, and transfer disease-resistant genes into soybean, wheat, and potato plants.
