Antarctica has not featured in these pages as much as tropical places, where we mostly work. The closest my work has come to Antarctica was between 2008-2010 when I worked with entrepreneurs in the Magallanes region of Chile, which includes Antarctica. Even then, the portions of my work in Tierra del Fuego were still 600+ miles from the northern most point of the Antarctic Peninsula. By contrast my work in Yakutia took me within the Arctic Circle. But in both places my work was always above ground, and never brought me close to the scientists working below ice shelves. So, thanks to Mother Jones for this:
Scientists taking sediment samples found animals nobody thought could survive there.
Bivouacked in the middle of the Filchner-Ronne Ice Shelf—a five-hour flight from the nearest Antarctic station—nothing comes easy. Even though it was the southern summer, geologist James Smith of the British Antarctic Survey endured nearly three months of freezing temperatures, sleeping in a tent, and eating dehydrated food. The science itself was a hassle: To study the history of the floating shelf, he needed seafloor sediment, which was locked under a half mile of ice. Continue reading

I am a cat person by nature. I have lost count of how many cats I had as pets since early childhood and well into adulthood, but I do remember our last two cats from three decades ago. Boris, a black cat with a tip of white on his tail, learned to jump up into my cradled arms if I stood in front of him and made a certain noise. His sister Mimi was named for the plaintive mi-mi cry she made when she climbed up onto the bathroom sink and rubbed her mouth against the faucet head, wanting us to turn the water on to drip out so she could drink. They lived long lives as indoor cats who did no harm to anyone or anything (that we knew of). But when we learned how many birds, among other wildlife, that cats kill per year we decided not to adopt any more cats; we switched to dogs. Now, all these years later, I am happy to see there is hope for reformed cat behavior:
Millions of pet cats are estimated to kill billions of animals a year but grain-free food can change cat behaviour
Feeding pet cats meaty food and playing with them to simulate hunting stops them killing wildlife, according to a study. Continue reading

A Volta’s electric eel in the Xingu River in northern Brazil. L. Sousa
Our attention to eels is only occasional, but the mysteries keep coming. The article contains an amazing video of this pack-hunting phenomenon. Thanks to Annie Roth for this:
The behavior, used by wolves and orcas to run down fast prey, is rarely seen in fish.
In August 2012, Douglas Bastos, then a graduate student at Brazil’s Instituto Nacional de Pesquisas da Amazônia, was exploring a remote waterway in the Amazon rainforest when he came across a small lake teeming with electric eels. Continue reading
If you can suspend judgement for a moment the awe is overwhelming:
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.

Researchers said that the blue whale song that crackled through the team’s underwater recordings was unlike any they had heard. Robert Baldwin/Environment Society of Oman
Thanks to Katherine J. Wu for this, especially for sharing the recordings of the whale song, and the musical reference for how to think about the difference between this whale population’s song and the that of other whale populations:
The whales in the group seem to sing a unique song.
Weighing up to 380,000 pounds and stretching some 100 feet long, the blue whale — the largest creature to have ever lived on Earth — might at first seem difficult for human eyes and ears to miss.
But a previously unknown population of the leviathans has long been lurking in the Indian Ocean, leaving scientists none the wiser, new research suggests. Continue reading
Bill McKibben‘s Climate Crisis newsletter this week has an interesting segment on the total weight of things humans have made, mentioning the book to the right for visual reference. Turns out our stuff now weighs more than all living things on the planet. That is impressive, but not necessarily in a good way:
We are necessarily occupied here each week with strategies for getting ourselves out of the climate crisis—it is the world’s true Klaxon-sounding emergency. But it is worth occasionally remembering that global warming is just one measure of the human domination of our planet. We got another reminder of that unwise hegemony this week, from a study so remarkable that we should just pause and absorb it. Continue reading

The image above, on its own, would be a mystery calling to be explained. Phoebe Weston has our attention again, this time with a story from the fungi universe:
Insect-destroying fungi ‘may represent the next frontier for drug discovery’

Two new fungi species that infect flies and eject spores out of a large hole in the insect’s abdomen “like small rockets” have been discovered in Denmark.
The new species, Strongwellsea tigrinae and Strongwellsea acerosa, are host-specific and rely on two species of Danish fly – Coenosia tigrina and Coenosia testacea, according to researchers at the University of Copenhagen. Continue reading

I had been putting off listening to this interview until I had the proper attention span. During the last two years I have worked to improve my understanding of the relationship between tastes and aromas (aka smells) of coffees, mirroring the work I did to better understand wines back in the day. My patience was rewarded with a clear conversation that neither dumbed down nor over-complicated the relationship between olfactory and gustatory experiences. It made me think the book will be worth more than the purchase price:
…On why grass-fed beef tastes different than grain-fed beef
It’s absolutely true that the foods that animals eat in order to grow affect the way they taste when we, in turn, eat them as food. And in the case of grass and grain-fed animals, the difference is in the kinds of fat that they take in. So it’s not that we’re actually tasting grass or tasting grain when we detect the difference between the two. It’s actually the fact that the fats — the oils in grass — are very irregular molecules, and they tend to be broken down in the animal into particular fragments that are very characteristic of those original fats and oils.

Researchers have spotted the Somali sengi, a relative of aardvarks and elephants, in Djibouti.
Steven Heritage/Duke University Lemur Center
We have used lost & found within post titles enough times since we started that maybe it should be a category. They are mostly happy surprise stories. More complicated than cute kitten videos, but worth the read. For now, our congratulations to the scientists who made the discovery and our thanks to National Public Radio (USA) for reporting this:
For more than 50 years, the mouse-size Somali sengi was thought to be a lost species.
Turns out, it wasn’t. Continue reading

As a study trumpets the food’s medicinal properties, there’s a buzz about beekeeping in the UK
Carly Hooper: ‘Bees are my life’. Photograph: Anita Parry
When honey made headlines this week as a better treatment for coughs and colds than antibiotics, beekeepers sat smugly by. “I’ve been saying this for ages,” says Carly Hooper, who has 12 hives near her home in Fleet, Hampshire, and a honey-based business.
The study, published in the journal BMJ Evidence Based Medicine, found that honey was a more effective treatment for coughs, blocked noses and sore throats than many remedies more conventionally prescribed. Continue reading
Food and Beverage as conservation themes have been long time interests at this site, whether it be recreating ancient ales or maintaining the artisan ethos of ancient food ways.
I have to admit that the blend of cuisine and archaeology are equally fascinating; I would have been one of the first of the “curious passersby” at the feast described here. The article is behind a paywall, but worth the read.
How Fuchsia Dunlop sampled food from the tomb of a long dead king
The four sheep turned on their spits, wafting out rich aromas over the bleached Turkish landscape. Nearby, I stirred a vast potful of lentil stew over an open fire, lashed by smoke and sunlight. A long table in the yard was already laden with dishes: handmade hummus and fava bean paste, whole honeycombs, stacks of tandoor-baked bread and piles of pomegranates. Beyond it loomed the great burial mound of a ruler of the Phrygian kingdom who had died here in the eighth century BC — thought to be a historical King Midas or his father. Aided by a team of Turkish cooks and food experts, I was doing my best to recreate his funeral feast.
This wasn’t an idle exercise. In the 1950s, archaeologists from the Penn Museum at the University of Pennsylvania had excavated the tomb, near the old Phrygian capital at Gordion. Although this King Midas was not the mythical man with the golden touch, they still found a treasure trove of bronze cauldrons, drinking bowls and clay pots in his burial chamber, including the largest Iron Age drinking set ever discovered. The vessels contained the physical remnants of a banquet the mourners had shared, but it was about 40 years before advances in science permitted chemical analysis of the residues.
This was done in the late 1990s by experts from the Penn Museum, led by Patrick McGovern, scientific director of its Biomolecular Archaeology Project for Cuisine, Fermented Beverages and Health, and author of Ancient Brews: Rediscovered & Re-created.
Using modern techniques such as infrared spectroscopy, liquid and gas chromatography and mass spectrometry, McGovern and his team examined the vestiges of both food and drink found in the bronze vessels. The mourners, they concluded, had shared an unusual brew made from a mixture of honey, grapes and barley — a sort of cocktail of mead, wine and beer. And although the researchers couldn’t be sure, they suspected it had also contained saffron because of the intense yellow colour of the residue (and because some of the finest saffron of the ancient world was produced in what is now Turkey).
The chemical detective work on the brown clumps of food matter showed these were the leftovers of a great stew made from lamb or goat that had first been seared over fire to produce caramelisation, then simmered with some kind of pulse (probably lentils) along with ingredients such as honey, wine, olive oil, fennel or anise and other herbs and spices.

Bees, in all their surprising ways, are important to humanity, so we share science about them. Our thanks to one of science writing’s most deft explainers, James Gorman, for one more insight. If only for the video, showing the precision of the bee’s ability to drink nectar, this article is worth a look:
Once again, insects prove to be more complicated than scientists thought they were.
For a century, scientists have known how honeybees drink nectar. They lap it up.
They don’t lap like cats or dogs, videos of whose mesmerizing drinking habits have been one of the great rewards of high speed video. But they do dip their hairy tongues rapidly in and out of syrupy nectar to draw it up into their mouth. For the last century or so, scientists have been convinced that this is the only way they drink nectar. Continue reading

This book (click the image to the left to go to the publisher) has become an unexpected bestseller. The other times we have posted on the topic of eels, a couple of them were artistic in nature and the other were scientific in nature. I would not have predicted that a whole book on the topic was something I would want to read, let alone that a very sizable audience would develop. I would expect that if there were to be more than four posts mentioning eels in the nine years we have been posting, we might have covered the topic of aquatic agriculture. But, no.
When I listened to a conversation (click the image to the right to go to the podcast) with the author of The Book of Eels it reminded me that I had already read a review of the book by Brooke Jarvis a few months earlier. And that we should post more on eels The illustration adorning the review was fun. The opening paragraphs were compelling:
The mysterious creature has attracted avid detectives since ancient times. Illustration by Jason Holley
In the spring of 1876, a young man of nineteen arrived in the seaside city of Trieste and set about a curious task. Every morning, as the fishermen brought in their catch, he went to meet them at the port, where he bought eels by the dozens and then the hundreds. He carried them home, to a dissection table in a corner of his room, and—from eight until noon, when he broke for lunch, and then again from one until six, when he quit for the day and went to ogle the women of Trieste on the street—he diligently slashed away, in search of gonads.

Thanks to Eric Vance for a fun and interesting read:
The animal world is full of games. And tucked in among wrestling monkeys, belligerent birds and wily coyotes are lessons for us all.
As a sophomore in college I interned at a lab that studied dolphin behavior. The animals spent most of the year doing back flips and spraying water onto tourists at a theme park, then called Marine World Africa USA, just north of San Francisco. In their off months, they hung out with behavioral scientists who did experiments with them.
I quickly noticed a few things about dolphin research. One, it’s regularly interrupted by dolphin sex. Dolphins are dirty, dirty creatures. Two, despite this, it’s actually quite dull. Watching dolphins swim in circles eight hours a day gets old. And three, almost all dolphin experiments involve games and toys. Continue reading

Thanks to the BBC for reminding us of the value of such voyages in earlier centuries, and their contributions to science, among other things:
The 3.5-year voyage to the furthest corners of the globe reshaped marine science and permanently changed our relationship with the planet’s oceans.

In the foyer of the National Oceanography Centre in Southampton, England, stands a ship’s painted figurehead. It towers well above head height and depicts an armoured knight with a silver chest plate, a raised visor and a thick handlebar moustache. The knight’s eyes have a faraway gaze in them – and well they might. This wooden statue is the sole remnant of a square-rigged ship that once embarked on a three-and-a-half-year voyage to the furthest corners of the globe, reshaping marine science, unearthing all manner of underwater oddities and permanently changing our relationship with the planet’s oceans. The vessel’s name was HMS Challenger. Continue reading
Our bee obsession on this platform has many explanations, but my personal motivation for following the science of bees goes back to a summer in the late 1970s when I worked for a beekeeper. I cleared brush and vines from the forest edge to make way for more bee-friendly plantings. I worked within sight of a dozen active bee colonies in boxes where I could see buzzing swarms constantly. I learned to be calm around them from the man who tended them. He used a poncho, a mask, and a smoker when opening the boxes to remove honey, but other times walked among them with no protective gear. To my surprise the resins from Toxicodendron radicans–poison ivy, poison oak and poison sumac–did more harm to me than the bees I worked around. In fact, I was never stung by those bees. Not once.
Which explains why when we finally had the chance to start our own bee colony I was all in. Above is a bee box, with found objects inside, above and below it. The bees inside had nested at the top of our house so we had a beekeeper extract them. He gave them this new home in a location where we have been clearing brush to make way for coffee planting. The old table had been in the chicken coop and the mysterious disk was on the roadside headed for recycling. One month later now, very happy bees.
Above is a small sampling of the vines and brush I have been clearing from the land near that hive. History may not repeat, but sometimes it rhymes. As it happens, on my arm I have some of the same toxins from vines like those 40 years ago. The clearing work started in March and is nearing completion to make way for several hundred shade trees and several thousand coffee plants.
One section of this clearing has already received twenty banana plants, based on the practice of our friends at Hacienda la Amistad. These make excellent companions to the coffee and are pollinated by bats, so provide another kind of ecological service too complex to discuss in a post primarily about bee surprises.
So, with all that in mind I was very happy to come across the story below by Cara Giaimo. Her work first appeared in our pages last October, then again a few months ago–both times related to birds. Somehow I missed this short article on bees from earlier this year, and I thank her for it now for making me laugh when there is not enough other news to laugh about:

Regurgitation is an important consideration when it comes to the process of pollination.
The bumblebee is a discerning nectar shopper. When choosing which flowers to gather the sticky substance from, it might consider a plant’s distance, the shape of the petals and how sugar-rich the nectar is. Continue reading
Microscopic plankton: they provide a food source for fish, seabirds and other marine life, as well as absorbing CO2 emissions
Although we’ve highlighted citizen science so many times on these pages, it never occurred to me that some of these projects have spanned nearly 9 decades.This particular project’s device is called a continuous plankton recorder (CPR). An apt acronym, indeed.
Since 1931 ‘citizen scientists’ on ships have enabled data collection on the tiny building blocks of the sea. Now this research could shape how we tackle the climate crisis
On a clear day, from their small, unassuming warehouse on the south Devon coast, Lance Gregory and Dave Wilson can see right across Plymouth Sound to the Eddystone lighthouse. Today, they’re watching a ferry from Brittany, the Armorique, pull into dock.
Behind it, the ferry is towing a one-metre-long device shaped like a torpedo. It doesn’t look like much, but it’s part of the planet’s longest-running global marine survey.
The device is called a continuous plankton recorder (CPR), and it’s one of 53 such devices that Gregory and Wilson manoeuvre using forklifts in their warehouse, surrounded by racks of distinctive yellow boxes and clipboards covered in spreadsheets.
They dispatch these CPRs in bright yellow boxes to “ships of opportunity” – ferries, cargo or container vessels that have agreed to volunteer for the mission. Once a ship leaves port, the crew attach the device to the stern using steel wire, then toss it overboard.
Trailing along behind the ship, it collects data for the CPR survey. The mission is vast but the subject is minuscule: plankton, the tiny organisms that drift in the ocean. Every marine ecosystem relies on plankton for its basic food source, and it generates half the oxygen we breathe. Perhaps more than any other organism, it is crucial to all life on our planet.
The CPR survey is the longest-running marine science project of its kind. It began in 1931 when the scientist Sir Alister Hardy investigated how herring were influenced by plankton in the North Sea. This month the distance surveyed will reach an impressive 7m nautical miles, equivalent to 320 circumnavigations of the Earth.
Since that first tow from Hull to Germany 89 years ago, the equipment has hardly changed. So far a quarter of a million samples have been analysed, representing a vast geographical spread over the course of the past century. The immense scope has allowed scientists to see dramatic patterns in ocean health, across both time and space, building a much clearer picture of how our marine environments are changing.
It is also, says Gregory, “one of the oldest citizen science projects in the world”. Continue reading
