At a time when microscopic phenomena are the cause of fear and loss, it is surprising and enlightening to read about microbial discoveries that could help answer some of the eternal questions about life, the universe, and everything.
Thanks to JoAnna Klein, who now more than ever is appreciated for the reminder of the wonders of natural history:
Before this underwater forest disappears, scientists recently raced to search for shipworms and other sea life that might conceal medicine of the future.
DAUPHIN ISLAND, Ala. — It was 6 a.m. at the dock on a Tuesday in December, and the weather did not look promising. Fog hovered over the water, and the engine of the Research Vessel E.O. Wilson rumbled.
Our ship disappeared into the mist, and by 7:30 the crew, a team of biologists, chemists and microbiologists, reached its destination. The sun lounged on obsidian water, masking a secret world where land and sea swap places, and past, present and future collide.
This is the underwater forest. Its unusual residents, shipworms and related marine organisms, could serve as incubators of unexpected medicines, churning out new lifesaving formulas and compounds that may not be found anywhere else on the planet. But first the group of scientists had to manage to dive 60 feet beneath the ocean’s surface to recover their unusual subjects, a task made more challenging by three days of uncooperative weather.
“Underwater forest” is not a metaphor — this is a not a coral reef or a sea grass bed that resembles surface woodlands but bona fide trees with roots and leaves. For thousands of years, this cypress grove — about two football fields long and five feet wide — lay silent, preserved within an oxygen-less tomb of sand and sediment. Then came Ivan.
In 2004, the hurricane, category 5 before making landfall, ripped through the Gulf of Mexico, with winds up to 140 miles per hour kicking up 90-foot waves. The storm scooped up nearly 10 feet of sand from the seabed, awakening the sleeping forest beneath. Continue reading

Experts discuss the science of smell and how scent, emotion, and memory are intertwined — and exploited
Thanks to Joanna Klein, as always:
Many amphibians — possibly all of them — are biofluorescent, according to a new survey.
Amphibians are half-landlubbers, half water-babies. They breathe through skin that is moist, warty, crested and in some cases, poisonous or hallucinogenic. Some wear dull, leaflike-camo patterns. Others sport Guy Fieri flames.
And as cute, gross, pretty, ugly, magical and witchy-named as these slip-sliding creatures may be, they’ve been hiding something in a secret, fluorescent world invisible to humans. Many amphibians, whether salamanders, frogs or their distant cousins — possibly all of them — glow, according to a survey published Thursday in Scientific Reports.
“There is still a lot out there that we don’t know,” said Jennifer Lamb, a biologist who conducted the research with Matt Davis, both at St. Cloud State University in Minnesota. “This opens up this whole window into the possibility that organisms that can see fluorescence — their world may look a lot different from ours.”
The study paves the way for new research into how or why amphibians possess this special adaptation, which has potential applications in medical technology and conservation. Continue reading
Having friends who fish using this technique, this is a tricky post to write. I knew little about the history of the lures used in fly fishing until yesterday. I learned a little something about this history that is as disturbing as the lures are admittedly beautiful. I have tried fly fishing and found it more difficult than any other outdoor activity I ever tried. I respect anyone with the talent required to catch fish this way. But now I wonder about the lures. Above is an extra feature from the episode of a podcast which, if you are a regular viewer of our daily bird feature, you will want to listen to. Click the image to go to that photo gallery for more, either before or after you listen to the podcast:
Victorian salmon flies are tied according to recipes that are up to 150 years old and call for some of the rarest feathers in the world. Our show this week is the story of what may be the greatest feather robbery of all time, a million dollars in rare birds, stolen from a British museum.
The community of people devoted to tying these kinds of flies doesn’t fish with them—they’re just for show. Many try to use feathers from the same species listed in the classic manuals. But because so many birds have been killed for so many reasons over the years, a lot of the most coveted species are now endangered or protected.
Below are some photos of salmon flies—the Durham Ranger, the Jock Scott, and the Sherbrook—and some of the birds referenced in the recipes used to make them.
The episode those photos support offers as well told a story as This American Life is known for, but for bird nerds it is especially rich. And for those who are yet to become bird nerds, it may be just the stimulus you need. To tie the most prized fishing fly, the most prized birds lose the ability to fly. :
A flute player breaks into a British museum and makes off with a million dollars worth of dead birds.
We do not like looking at them. They disrupt many otherwise pristine views of nature, in the most surprising places. And so the thought of them being dangerous to birds would be an easy stretch of the imagination. Thanks to Audubon for the clarification, that their danger to birds is just an act of imagination:
Here’s the truth behind a Facebook falsehood spreading across the internet.
On the internet, there is often a fine line between a healthy skepticism of new technologies and blatant misinformation. The recent claim that the radio waves from 5G cellular communication towers are causing mass bird die-offs is a perfect example of just how thin that line can be—and how quickly falsehoods can spread across Facebook, Twitter, YouTube, and even in the comments of Audubon magazine’s stories.
The origin of this claim is as head-spinning as it is instructive, so let’s untangle the knot: Does 5G really kill birds, and if not, why are so many people shouting about it online? Continue reading
The plan provides one possible answer, its execution is an important question:
Paris-style proposal to counter loss of ecosystems and wildlife vital to the future of humanity will go before October summit
Almost a third of the world’s oceans and land should be protected by the end of the decade to stop and reverse biodiversity decline that risks the survival of humanity, according to a draft Paris-style UN agreement on nature.
To combat what scientists have described as the sixth mass extinction event in Earth’s history, the proposal sets a 2030 deadline for the conservation and restoration of ecosystems and wildlife that perform crucial services for humans.
The text, drafted by the UN Convention on Biological Diversity, is expected to be adopted by governments in October at a crucial UN summit in the Chinese city of Kunming. It comes after countries largely failed to meet targets for the previous decade agreed in Aichi, Japan, in 2010. Continue reading
Thanks to Nell Greenfieldboyce, science correspondent at National Public Radio (USA), for summarizing findings about how some animals help one another. We are on the lookout for more stories of how, why, when acts of kindness happen, and if we need to turn to parrots for inspiration, no problem:
Parrots can perform impressive feats of intelligence, and a new study suggests that some of these “feathered apes” may also practice acts of kindness.
African grey parrots voluntarily helped a partner get a food reward by giving the other bird a valuable metal token that could be exchanged for a walnut, according to a newly published report in the journal Current Biology. Continue reading
A growing body of research points to the beneficial effects that exposure to the natural world has on health, reducing stress and promoting healing. Now, policymakers, employers, and healthcare providers are increasingly considering the human need for nature in how they plan and operate.
How long does it take to get a dose of nature high enough to make people say they feel healthy and have a strong sense of well-being?
Precisely 120 minutes. Continue reading
Thanks to Audubon Magazine we start 2020 with a short story about an adaptation that is not just pretty, but practical in more than one way:
Good for more than just attracting a mate, the clownish feature appears to keep the subpar fliers from overheating.
The puffin’s iconic orange bill might be its most recognizable feature, but it’s also quite functional, serving the charismatic seabird in all avenues of life. The bill’s large volume makes it a hefty food carrier, and its ultraviolet glow amps up puffins’ sex appeal. Now, scientists have identified yet another use of this dramatically curved bill: staying cool. Continue reading
Thanks to Discover Magazine’s Sarah White for bringing our attention to Three Studies Are Showing Bees’ Amazing Math Abilities, a story we had missed earlier:
Honeybees caused quite a buzz this year when three separate studies showed they possess some of the same mathematical abilities as humans, despite much tinier brains.
In February, research in Science Advances indicated honeybees could learn to add and subtract. To teach the bees arithmetic, cognitive scientists set up a Y-shaped box for the bees to fly through. When a bee entered the box at the bottom of the Y, it saw blue or yellow shapes. If the shapes were blue, the bees were trained to fly down an arm of the Y toward a picture with one additional shape to receive a sucrose reward; the other arm had a bitter drink instead. If the shapes were yellow, bees were rewarded for choosing the picture with one fewer shape…

Experiments reveal how visual cues reorganize course-sensing neurons in fruit flies
Companies like Impossible and its competitor Beyond Meat have gotten most of the attention in our pages for plant-based meat-like products, but when it comes to alternative seafood our stories have mainly focused on invasive species, or on farming kelp or on seaweed farming. Thanks to Mother Jones for stretching our attention to the alternatives to fresh caught or even farm-raised seafood that simulates the kinds of fish that have been over-harvested:
This is why we can’t have nice things.
Do you love burgers—but not the animal cruelty and environmental degradation that go into making them? I come bearing good news: Someday, you might be able to get your meat fix, without all that bad stuff. Scientists can now grow animal flesh, without raising—or in most cases killing—an animal. This food, called “lab-grown meat,” “cell-based meat,” “cultured meat,” “cultivated meat,” “clean meat,” or as comedian Stephen Colbert jokingly called it in 2009, “shmeat,” has set off a flurry of media attention in recent years. Dozens of lab-grown meat companies have materialized, most aiming to solve the problems associated with large-scale beef, pork, poultry, and seafood production.
Finless Foods, a 12-person food-tech startup founded in 2017 and based in Emeryville, California, claims to be the first company to focus on lab-grown fish, although a handful of other startups have since joined them. In October, 28-year-old Finless Foods co-founder Mike Selden gave me a tour of their facility, and I dished about it on the latest episode of the Mother Jones food politics podcast Bite:
Selden and his co-founder Brian Wyrwas, both products of an agricultural biochemistry program at UMass Amherst, started the company, he says, to “make something good.” Continue reading
Thanks to Caitlin McDermott-Murphy for this story about cleaning up our growing systems:
How a biofriendly fertilizer could offer a greener way to grow plants
Every year, a “dead zone” the size of Massachusetts sprawls across the Gulf of Mexico. The Mississippi River, which travels through the nation’s farm belt, sweeps excess fertilizer and dumps the chemicals into the Gulf, where they feed rampant algae, deplete oxygen, and kill marine life.
Across the U.S., smaller versions of similar dead zones infect lakes, ponds, and rivers. In years with higher rainfall — like 2018 — Massachusetts’ Charles River collects enough pollutants from surrounding city streets, parking lots, and landscaped campuses to cause the water quality to drop. Unchecked algae growth, often the result of excess fertilizer, can damage marine, human, and even pet health: This year, several dogs died after swimming in water choked with toxic blue-green algae.

Camera traps have proven valuable in the work we have been doing in Belize, India and elsewhere in the wilderness areas of the developing world. But equally important are the photos captured in areas closer to urban settlements. Thanks to The Nature Conservancy’s publication of these photos with the article below:
As a Nature Conservancy forester in Pennsylvania, Mike Eckley spends a lot of time assessing the health of woodlands. That means he spends as much time thinking about white-tailed deer as he does trees.
Many conservation biologists consider over-abundant deer to be an even bigger threat to eastern forests than climate change. Deer can fundamentally change the forest ecosystem, threatening everything from rare wildflowers to migratory songbirds. These deer also can cause deadly vehicle collisions, increase risk of Lyme disease, and cause significant agricultural and property damage.
Eckley educates hunting clubs and landowners on deer management issues, and recently co-edited a book on the topic. He also works to make sure the deer herd is healthy on Conservancy projects like the West Branch Forest Preserve, a 3,000-acre preserve in north central Pennsylvania. Continue reading
Two weeks ago I promised an update from the field, and after completing the necessary government permits and preparing for work in the forest, I’m finally ready to write about the summer project that the Yale School of Forestry and Environmental Studies requires of its Master of Environmental Management candidates. We can choose between completing an internship or independent research, and I opted for the latter, since I wanted the experience of designing my own field season and collecting data for scientific analysis for peer-reviewed publication, pursuing a subject that I’m both personally and academically interested in: tropical bird conservation. Now, with the generous support I’m grateful to receive as a fellow of the Yale Institute for Biospheric Studies (YIBS), Yale’s Tropical Resources Institute (TRI), and the University of Rwanda’s Center for Excellence in Biodiversity and Natural Resource Management (CoEB), I’ve started my project exploring a subset of montane avifauna distribution in the Albertine Rift.
On the shore of almost any body of water in Akagera National Park in the east of Rwanda, trees festooned with balls of dried grass are a common sight, although what will often draw your attention to these trees first is not the strange vegetation, but the cacophony of a dozen or more weaver birds chattering away as they bring strands of grass to build these nests, display to potential mates, or warn of possible predators. The species featured here, the Village Weaver Ploceus cucullatus, is a fairly common bird in this region, and entertained us with their craft on the day that we visited Lake Ihema, the second largest lake in Rwanda after Lake Kivu to the west.
It would never have occurred to me to think about this, but I am fine with the surprise:

The blurb from his own university’s news service is enough to catch your attention:
Drawing on advances in social science, evolutionary biology, genetics, neuroscience, and network science, “Blueprint” attempts to show how and why evolution has placed us on a humane path — and how we are united by our common humanity.
For too long, the author contends, scientists have focused on the dark side of our biological heritage: our capacity for aggression, cruelty, prejudice, and self-interest. But natural selection has given us a suite of beneficial social features, including our capacity for love, friendship, cooperation, and learning. Beneath all our inventions — our tools, farms, machines, cities, nations — we carry with us innate proclivities to make a good society.
There are not many reviews available yet, but here is one:
A social scientist looks at the good and bad sides of human character, arguing that we are evolutionarily inclined “to make a particular kind of society—a good one full of love, friendship, cooperation, and learning.”…
…A refreshingly optimistic view of our kind.
If, like me, you had previously only known of him due to this incident, the blurb and the review are catchy enough to warrant further attention. So I found an interview he recently gave (on a podcast I would not normally have sought out, but it was all I could find) and listening to him talk about it has made me want to find this book and have a read.
While on the topic of food, thanks to Dustin Solberg and Cool Green Science for this:
Quite a few years back, while working the wheat harvest in the middle of Oklahoma, I met a leathery skinned farmer. He lived through the dusty, hardscrabble, droughty years of the Great Depression, and experience had taught him plenty. I still recall his silver belt buckle, his straw cowboy hat, and the funny joke he told me about the buffalo on a buffalo nickel, which I can’t repeat here. He wanted me to know, and so told me in no uncertain terms, that there’s one way, and one way only, to plow a field.
We were standing then in the fresh golden stubble of a wheat field. It was hot. We’d just finished combining and after a day of steady motion we were finally still, the diesel engines at rest. I can still recall the animated force in his muscly hands – he made his fingers into the tines of a chisel plow – to make his point as vividly as I recall what he said: “You’ve got to set the plow deep.”
The trouble was, he was wrong.
