Infrared enabled contact lenses
Every day we get a little closer to the future, and recently, Chinese scientists have created contact lenses that can see infrared light.
The team screened various biocompatible polymeric materials (used to make commercial contact lenses) to find just the right refractive index and optical and mechanical properties, and integrated them with the aforementioned nanoparticles to make upconversion contact lenses (UCLs). Then they tested their lenses on mice, giving them a choice between a dark box and a box illuminated with infrared light. Mice wearing the contacts chose the dark box; those without augmented vision showed no preference. And the pupils of the contact-wearing mice constricted in response to infrared light, while brain imaging showed the visual processing centers reacting to it as well. -
Growing Sequoias in Detroit
An effort started in 2020, seeks to grow an urban forest of sequoias in Detroit.
Giant sequoias are not native to Michigan. And, yet, they’re somehow thriving in the state, which has a much cooler and wetter climate than their native California.
The biggest giant sequoia east of the Rockies is a 77-year-old specimen, called the Michigan Champion, that was planted in 1948 on the eastern shores of Lake Michigan. The tree measures roughly 116 feet tall and 5 feet in diameter.
“They’re safer here … we don’t have wildfires like [California],” Kemp tells the Associated Press. “The soil stays pretty moist, even in the summer. They like to have that winter irrigation, so when the snow melts they can get a good drink.”

Drone summons lightning
It’s like something out of a sci fi movie–a drone summoning lightning.
Earlier this month, the Japanese telecommunications company Nippon Telegraph and Telephone Corporation (NTT) successfully used a drone equipped with a lightning-proof cage to essentially summon lightning in an effort to mitigate damage from an incoming thunderstorm. According to NTT, lightning causes up to 200 billion yen ($1.4 billion) damage a year, so using these lightning drones could go a long way towards protecting sensitive equipment and population centers during severe weather events.

A universal antivenom
It sounds like a joke based on a basic misunderstanding of science, but a man who’s been slowly injecting himself with snake venom may now provide a source for a universal antivenom.
Over nearly 18 years, the man, Tim Friede, 57, injected himself with more than 650 carefully calibrated, escalating doses of venom to build his immunity to 16 deadly snake species. He also allowed the snakes — mostly one at a time, but sometimes two, as in the video — to sink their sharp fangs into him about 200 times.
This bit of daredevilry (one name for it) may now help to solve a dire global health problem. More than 600 species of venomous snakes roam the earth, biting as many as 2.7 million people, killing about 120,000 people and maiming 400,000 others — numbers thought to be vast underestimates.

Cats bringing dead gifts
My mother feeds a local feral cat named, Rigby. While the cat has never left dead gifts, he has been seen carrying dead animals. Most recently, a squirrel.
There are a couple of hypotheses for why cats bring their catch home, Emmanuelle Baudry, an urban ecologist at Paris-Saclay University, told Live Science. The main hypothesis is that this behavior is maternal. In the wild, mother cats go out and hunt and then bring the food back for their kittens. This not only feeds the young cats but also provides something for them to play, practice how to hunt and recognize prey. So, in the context of human pet owners, our cats may see us as “not so efficient kittens,” Baudry said.
But that doesn’t mean your pet is insulting you. To the contrary: “It’s somewhat of a compliment,” Liff told Live Science. “They feel comfortable in their home. They consider you part of their family.

Making music after death
Popular Mechanics with an interesting art installation involving posthumous brain matter to make music.
American composer Alvin Lucier was well-known for his experimental works that tested the boundaries of music and art. A longtime professor at Wesleyan University (before retiring in 2011), Alvin passed away in 2021 at the age of 90. However, that wasn’t the end of his lifelong musical odyssey.
Earlier this month, at the Art Gallery of Western Australia, a new art installation titled Revivification used Lucier’s “brain matter”—hooked up to an electrode mesh connected to twenty large brass plates—to create electrical signals that triggered a mallet to strike the varying plates, creating a kind of post-mortem musical piece. Conceptualized in collaboration with Lucier himself before his death, the artists solicited the help of researchers from Harvard Medical School, who grew a mini-brain from Lucier’s white blood cells. The team created stem cells from these white blood cells, and due to their pluripotency, the cells developed into cerebral organoids somewhat similar to developing human brains.

Mirrors, how do they work?
Apparently there was a whole thing on TikTok about mirrors being able to see behind a piece of paper. People emphatically stating mirrors can’t when its a little more nuanced. Mirrors break our brains.

Dog college
Dog college sounds fun.
“The most important thing is they’re doing what they love,” says Ruth Desiderio, the center’s volunteer and outreach coordinator leading the public tour I’ve joined in on. The dogs, she explains, indicate their interests and aptitude through apparent eagerness and ambivalence, and are allowed to proceed accordingly. If a dog relishes the challenge of sniffing out a hidden human, but reacts with fear to loud, sudden banging sounds–perhaps they’re destined for wilderness over urban search and rescue. If they love to smell and be rewarded, but crave routine, then a long-term post in the lab could be the perfect fit.
