Lots of lovely shots. "For three weeks in February 2026 I was in the highlands of Angola — the plateau that feeds the Okavango, Zambezi, Congo and Cuanza rivers — on a biodiversity survey called the Cassai Life Atlas. […] Most of this plateau has never been surveyed, and not for lack of interest — it’s been sitting behind decades of landmines left over from Angola’s civil war." https://www.nickybay.com/cassai-life-atlas-angola-2026/ #Africa #Angola #Spiders #Insects #Snakes #Surveys #Biodiversity

@gregeganSF@mathstodon.xyz @startswithabang@mastodon.social also did the calculations and came to this conclusion. "The most unfortunate part of the Reflect Orbital proposal is how unnecessary it is. We already have solutions to all of the problems that it purports to solve, with none of the many significant consequences that an array of giant mirrors would bring to Earth." https://bigthink.com/starts-with-a-bang/true-cost-solar-power-night-reflect-orbital/

"Because of these and other audacious experiments, the particle that Pauli was sure could never be caught has slowly been revealing its secrets. The recipe for discovery hasn’t changed in seven decades: Think big, go deep, and summon patience." https://www.quantamagazine.org/how-physicists-track-and-trap-the-elusive-neutrino-20260624/ #Particle #Physics #Neutrino #Detectors #BigScience

"Robert Tinney passed away on February 1st, 2026.
[...]
He was the artist behind the beautiful hand-painted covers of the influential computer hobbiest magazine Byte from the December 1975 issue until the early '90s.
[...]
Tinney's career didn't begin or end with Byte. He worked for a range of electronics companies and magazines [...] doing plenty of covers and advertisements that have rarely been collected or highlighted."

RIP. I've seen his remarkable footage in various BBC Wildlife documentaries.

"The acclaimed wildlife cameraman and photographer Doug Allan has died while trekking in Nepal.

Allan, 74, was principal cameraman on a number of BBC programmes including The Blue Planet, Blue Planet II, Planet Earth and Frozen Planet, and spent much of his career working alongside Sir David Attenborough."

"Male dragonflies are known to engage in mid-air “dogfights” to defend their breeding territory, using different maneuvers than those they employ when hunting prey. A new paper published in the Journal of the Royal Society Interface concluded that relatively simple rules drive that behavior, namely that male dragonflies are trying to maintain a tactical position. This mirrors the tactics of human fighter pilots." https://arstechnica.com/science/2026/07/dragonflies-maneuver-like-fighter-pilots/ #Dragonflies #Behaviour #Biology

"Flies (Diptera) are particularly suitable transport hosts. They are highly mobile, capable of long-distance flight, and frequently visit the same types of transient habitats that pseudoscorpions depend on. By attaching themselves to a fly, pseudoscorpions can effectively outsource dispersal – reaching new habitats they could never access on their own."

"Creating a conlang involves much more than stringing together some make-believe words. Languages are complex machines with many interlocking parts, and linguists must wield their expertise in these systems to create functional languages that suit their fictional speakers. That careful engineering not only adds depth and realism to many fantastical realms. It may also offer insight into the nature of language itself."

"A survey of 169 trees found 11 latrines—all of them in the major forks of the strangler fig tree (Ficus tuerckheimii). A camera trap at one arboreal potty captured 17 different species visiting the spot. The findings, published March 16 in Ecology and Evolution, suggest that treetop toilets might provide communication hubs across mammal species."
