They Rolls up into a Ball…

today’s obsession is ancient tattoos, in particular the s-curved floral-antlered deer of the Siberian Ice Maiden and Scythian Chieftain. 

it’s such a heavily used trope in modern media (off the top of my head I can think of Pokemon, Annihilation, Bambi, Snow White and the Huntsman, etc) and why wouldn’t it be! antlers look like branches, branches look like antlers, it’s only natural to pair them

but it makes me strangely emotional that our brains have always worked this way, and been drawn to the same imagery over and over again. 

I’m also going to resist the urge to make paired enamel pins of these ancient deer, even though I deeply desire little wearable tributes of the past

"The Seychelles has become a major tourist destination for beachgoing and scuba diving, but it’s not only humans that are beginning to flock to this island.

In what marine biologists have described as a “phenomenal finding,” a survey of whales around the territorial waters of this archipelagic nation revealed the presence of blue whales—over a dozen.

It’s the first time they’ve been seen in these warm seas since 1966, and it’s a wonderful milestone in a long and increasingly successful recovery for the world’s largest animal.

The Seychelles are located in the Indian Ocean off the east coast of Africa, and they were historically a stopover point for Soviet whalers en route to Antarctica. The years 1963 to 1966 were particularly difficult for whales here, and many were taken before the International Convention on the Regulation of Whaling put an end to the practice of hunting baleen whales in 1973.

Since 1966, no dedicated investigation of whales in the Seychelles had been made until 2020, when a partnership of four universities conducted an acoustic survey over the period of two years.

They made five different sightings of groups of up to 10 animals.

“This was a phenomenal finding,” Jeremy Kiszka, a co-author of the paper from Florida International University, wrote in The Conversation. “We were prepared to not see any blue whales due to the high level of hunting that occurred fairly recently and absolutely no information was available since the last blue whale was killed in the region in 1964.” ...

The team behind the survey sent images taken of the whales’ dorsal sides to a database to see if any of them had been recorded before, and amid the reel, not a single one was a match with any other photographed whale.

This, the team suggests, means they have probably never been seen before, which for a species that big might seem strange, but along with there being only 5,000 to 15,000 on Earth, they migrate vast distances while diving deep, making recording their movements incredibly challenging.

The survey identified 23 whale species in total using hydroponic mics over 2 years with peak activity coming between December and April. This is a fascinating finding that suggests something about the seas around the Seychelles makes for excellent whale habitat."

No, you can’t pet that dog. ✋ Introducing the bush dog (Speothos venaticus)! This rare canid is so elusive that it was once known only from fossils and thought to be long extinct. It inhabits parts of South America from Panama to northern Argentina, where it can be found in packs of up to 12 individuals. With partially webbed feet, this critter is a skilled swimmer and spends much of its time around water. It hunts for a variety of rodents including agoutis, pacas, and capybaras.

Indian Engineers Tackle Water Shortages with Star Wars Tech in Kerala https://www.goodnewsnetwork.org/indian-engineers-tackle-water-shortages-with-star-wars-tech-in-kerala/

When a severe water shortage hit the Indian city of Kozhikode in the state of Kerala, a group of engineers turned to science fiction to keep the taps running.

Like everyone else in the city, engineering student Swapnil Shrivastav received a ration of two buckets of water a day collected from India’s arsenal of small water towers.

It was a ‘watershed’ moment for Shrivastav, who according to the BBC had won a student competition four years earlier on the subject of tackling water scarcity, and armed with a hypothetical template from the original Star Wars films, Shrivastav and two partners set to work harvesting water from the humid air.

“One element of inspiration was from Star Wars where there’s an air-to-water device. I thought why don’t we give it a try? It was more of a curiosity project,” he told the BBC.

According to ‘Wookiepedia’ a ‘moisture vaporator’ is a device used on moisture farms to capture water from a dry planet’s atmosphere, like Tatooine, where protagonist Luke Skywalker grew up.

This fictional device functions according to Star Wars lore by coaxing moisture from the air by means of refrigerated condensers, which generate low-energy ionization fields. Captured water is then pumped or gravity-directed into a storage cistern that adjusts its pH levels. Vaporators are capable of collecting 1.5 liters of water per day.

If science fiction authors could come up with the particulars of such a device, Shrivastav must have felt his had a good chance of succeeding. He and colleagues Govinda Balaji and Venkatesh Raja founded Uravu Labs, a Bangalore-based startup in 2019.

Their initial offering is a machine that converts air to water using a liquid desiccant. Absorbing moisture from the air, sunlight or renewable energy heats the desiccant to around 100°F which releases the captured moisture into a chamber where it’s condensed into drinking water.

The whole process takes 12 hours but can produce a staggering 2,000 liters, or about 500 gallons of drinking-quality water per day. Uravu has since had to adjust course due to the cost of manufacturing and running the machines—it’s just too high for civic use with current materials technology.

“We had to shift to commercial consumption applications as they were ready to pay us and it’s a sustainability driver for them,” Shrivastav explained. This pivot has so far been enough to keep the start-up afloat, and they produce water for 40 different hospitality clients.

Looking ahead, Shrivastav, Raja, and Balaji are planning to investigate whether the desiccant can be made more efficient; can it work at a lower temperature to reduce running costs, or is there another material altogether that might prove more cost-effective?

They’re also looking at running their device attached to data centers in a pilot project that would see them utilize the waste heat coming off the centers to heat the desiccant.
