The pandemic coronavirus has made its way onto two mink farms in Utah, leading to “unusually large numbers” of dead animals, according to a Tuesday announcement by the US Department of Agriculture.
These are the first reported cases of the coronavirus, SARS-CoV-2, infecting mink in the country. For months, authorities in European countries, including the Netherlands, Denmark, and Spain, have reported outbreaks in mink pelt farms, leading to the culling of more than a million of the soft, furry mammals. From laboratory experiments, it’s also clear that ferrets, a relative of minks, are also readily infected with the novel coronavirus.
The affected farms in Utah reported cases of COVID-19 in people working on the farms, who may have spread the infection to the animals.
Cattle herds in the Okavango delta region in Botswana are plagued by attacks by lions and other predators, prompting farmers to retaliate by killing the predators. An alternative nonlethal technique involves painting eyes on the butts of cattle to trick ambush predators like lions into thinking they’ve been spotted by their intended prey. It’s called the “Eye-Cow Project,” and a recent paper published in the journal Communications Biology provides some solid empirical evidence for the practice. There are now practical guides for using the “eye-cow” technique available in both English and Setswana, so farmers can try it out for themselves.
Neil Jordan, a conservation biologist at the University of New South Wales in Australia, came up with the idea several years ago while he was doing field work in Botswana. Local farmers killed a pair of lionesses in retaliation for preying on their herds of cattle, and Jordan wanted to come up with a non-lethal alternative. The African lion population has dropped significantly from more than 100,000 in the 1990s to somewhere between 23,000 and 39,000 in 2016—much of it due to retaliation killings.
Jordan knew that butterfly wings sporting eye-like patterns are known to ward off preying birds, and are also found in certain fish, mollusks, amphibians and birds, although such patterns had not been observed in mammals. He also discovered that woodcutters in Indian forests have been known to wear masks on the backs of their heads to discourage any tigers hunting for prey. He had observed a lion stalking an impala, and noticed the predator gave up the chase when the prey spotted it. Lions are ambush hunters, Jordan reasoned, and decided to test his “detection hypothesis” that painting eyes on the butts of cows would discourage predatory behavior from the local lion population.

In the darkest depths of the ocean, where little to no light from the surface penetrates, an unusual array of creatures thrives, many of which create their own light via bioluminescence to hunt for prey, among other uses. But there are also several species of fish that have evolved the opposite survival strategy: they are ultra-black, absorbing nearly all light that strikes their skin, according to a new paper in Current Biology.
Karen Osborn of the Smithsonian’s Museum of Natural History became intrigued by the creatures upon finding she was unable to capture these ultrablack fish on camera while working in the field, trying to photograph specimens caught in the team’s deep-sea trawl nets. “Two specimens, the Anoplogaster cornuta and the Idiacanthus antrostomus, were the only two fish over the course of six years of field work that I was able to get decent photographs of,” Osborn told Ars.
To do so, she used a Canon Mark II DSL R body and 65 mm macro lens with four strobes, then tested various lighting setups by taking lots and lots of photographs. Finally, she adjusted contrast and applied a high pass filter uniformly across the images, the better to bring out the details. It still wasn’t sufficient to capture most of the specimens caught in the trawl net. “Over the years I deleted thousands of failed shots of other fish as useless because I couldn’t bring out the details in the photos,” she added. “It didn’t matter how you set up the camera or lighting—they just sucked up all the light. I wish I had a few of them now to illustrate this.”
Researchers have found fish that absorb more than 99.9 percent of the light that hits their skin.

The diminutive gecko is capable of some extraordinary feats of locomotion, zipping along vertical walls with ease and even running short distances across water. Precisely how they accomplish these feats has long interested scientists. A new paper in Proceedings of the Royal Society B reports that geckos’ ability to reorient their flexible toes is a major factor, enabling them to realign and adjust to shifts in gravity (load). The work may one day help to improve the design of bio-inspired robots.
This work builds on a 2018 study from the laboratory of University of California, Berkeley biophysicist Robert Full. Geckos are known for being expert climbers, able to stick to any surface thanks to the tiny hair-like structures on the bottoms of their feet. The little lizards can also zip along the surface of water at high speeds to elude predators. They can’t do it for very long; the energy expenditure required is too great. But it’s amazing that they can do it at all.
As we reported in 2018, those creatures in nature capable of walking on water employ different mechanisms depending on their size. Small, lightweight water striders, for instance, rely entirely on surface tension to stay afloat, while the larger, heavier basilisk lizards employ a slapping motion with their feet that creates pockets of air bubbles to keep from sinking. The standard theoretical calculations set very strict boundaries for how small an animal has to be to use surface tension and how large it needs to be before the surface slapping mechanism is viable.

Vampire bats can starve to death if they don’t feed for a mere three days, so strong social ties can be key to survival. For instance, a bat will sometimes share food with a hungry member of the same roost, regurgitating any blood it has consumed into the mouth of the hungry bat—a bit like a bloody French kiss. That’s a true “friend.” Evolutionary biologists have dubbed this behavior “reciprocal altruism.” But vampire bats can also form bonds with strange bats from outside the roost, building up trust with mutual grooming first before moving on to food sharing, according to a new paper in Current Biology.
What’s being tested here is a game theory model first proposed in 1998 colloquially known as “raise the stakes.” It’s similar to the famous prisoner’s dilemma, in which two criminal suspects are arrested and separately offered a deal. If one of them confesses and the other doesn’t, the defector will go free and the other suspect will get 20 years in jail. If both suspects confess, they will each get ten years in jail. The correct strategy, therefore, is to always confess, since one should assume the other party will act solely in his or her self-interest. Both players will reap the most benefit by cooperating with each other.
But cooperative behavior isn’t always quite so simple as a binary choice between cooperating or defecting; it’s more like a continuously variably investment. The “raise the stakes” model of relationships holds that two strangers can make low-risk, incremental investments to see if there is potential for further cooperation. If the other party reciprocates in kind, it builds trust and a relationship can form. If not, no relationship will develop, and nobody has spent too much time and energy on a worthless (from a survival standpoint) connection.
