Samsung galaxy z fold 6 - Wow, It's FINALLY Happening A lot of current flagship phones, such as those with the Z Fold 5, are equipped with two batteries that allow for faster charging that can reach 25W. It's not likely to be the case that Z Fold 6 will reach this level but it's worthwhile to mention that the present Galaxy S24 Ultra can reach 45 Watt charges, but only with Samsung's charging system.

The weirdly competent Doctor

So! The Watchtower's Medical Bay is a hub of constant Activity. With the number of Heroes who work under the Justice League, there are always injuries, health check-Ups, and illnesses that need healing.

But with the amount of Variant Biologies that those Heroes have, it's always a guessing game as to how to help them best. Some Metahumans react positively to penicillin, but others react like it's their Kryptonite. Some Aliens have anatomy similar to Humans, others are so different you can't tell the Stomach from the Bladder.

So when they hired a New Doctor for the Medical Bay, they had to run him through an entire Course on Variant Biologies and how best to treat specific Heroes. It was long and difficult to remember fully, but it was necessary for him to know.

But then the new Doctor started correcting Them.

"Actually, Martian's react better to the Syrup of Eucalyptus Plants better than Penicillin, since Eucalyptus is very similar to a medicinal plant from Mars which they used in many of their antibiotics."

"I don't think just pumping double doses of sedative is the best way to calm down a Speedster, that could have adverse effects on their body. Perhaps try Psychic Intervention? Their minds move a Mile a Second, but if you can calm them down their bodies will follow suit."

"Of course you use Micro-Doses of Kryptonite to operate on Superman! What else would you do?! I don't know, maybe ask JLD to enchant your Equipment to make use of Kryptonian suseptiblity to Magic? The Kryptonite is just gonna give him Cancer!"

Of course the Doctors didn't take kindly to being rudely corrected by a newbie, and Fired him on his first day.

Then a few days later their usual Treatments don't work, and they decide to give those strategies the Quack Doctor gave them out of desperation.

And Lo and Behold, they work! Martian Manhunter is fully healed and feels much better than the previous times he has needed surgery. Apparently they used a different Antibiotic that worked better with his Biology. Which was incredible, how had they figured it out?

Another Doctor you say? One who was experienced on Martian Biology and Medicinal History? He would very much like to meet with the man!

...

What do you mean you fired him for talking back?!

Restoring Indigenous aquaculture heals both ecosystems and communities in Hawai‘i

For generations, native Hawaiians have understood that their aquaculture systems, fishponds known as loko i‘a, serve as nurseries that seed fish populations in surrounding waters. For the first time, a team of scientists from the Hawaiʻi Institute of Marine Biology (HIMB) have modeled this feat of Indigenous science in a study.

“We are using science to translate ‘ike kupuna, or Indigenous knowledge, into policy,” said study co-author Kawika Winter, an ecologist at HIMB and He‘eia National Estuarine Research Reserve (NERR).

“The value of this paper is that it’s one of the first, if not the first, to really show that there are ways to do aquaculture in ways that benefit the system around it.”

In partnership with He‘eia NERR and Paepae o He‘eia, a nonprofit organization dedicated to stewarding the He‘eia loko i‘a, an ancient Hawaiian fishpond enclosing 36 hectares (88 acres) of brackish water, the team simulated different restoration scenarios in Kāne‘ohe Bay on O‘ahu Island based on a simplified food web. The study found that restoring more of the bay into fully functional loko iʻa would grow fish populations not just within the ponds, but across the bay.

“Aquaculture has a really bad reputation for basically destroying areas around it, but those are commercial approaches to aquaculture that aren’t holistic in their thinking or values-based like Indigenous management,” Winter said. “Rather than ensuring the health of the system, commercial aquaculture is concerned with maximizing profits.”

Winter attributed the success of the loko i’a design to Indigenous thought processes: “Indigenous thinking is operating within the opportunities and constraints of this system and figuring out a way to make things abundant within that context, sometimes even increasing abundance beyond natural levels.

Restoring ecosystems and relationships

Since co-founding Paepae o He‘eia in 2001, study co-author Hi‘ilei Kawelo, a sixth-generation Hawaiian from Kāne‘ohe Bay, has witnessed thousands of volunteers transform the He‘eia loko i‘a.

With the ongoing restoration, Paepae o He‘eia has seen both the aquatic environment and participants’ well-being improve with increased access to traditional foods, strengthening their relationship to place, and fortifying their family and community relationships. “For me and for a lot of our employees, this is one of our outlets, if not our primary outlet for exercising aloha ‘āina [love of the land],” Kawelo said.

“‘Āina is so important, because it is a term for a system that has the nature and its people in an inseparable reciprocal relationship,” Winter said. “The concept is core to this work because it’s about getting back into a way of thinking where there is no separation between the lands, the waters and us.”

While the overarching goal of Paepae o He‘eia and other fishponds is to revitalize Hawai‘i’s extensive Indigenous aquaculture system, Kotubetey said he knows the work may take generations.

I think it’s neat that the Phineas and Ferb characters aren’t into summer because they dislike learning or math or anything like that. These kids actually LOVE math & science & the arts. They love summer because it gives them more free time to work on personal projects using those skills

Science is magic 🤔

Everytime I hear someone say "love is what makes us human"I think of that one guy who was trying to describe humanity and said humans were featherless bipedals and another guy responded to that claim by bringing in a plucked chicken saying "BEHOLD A MAN"

Like I could hold up a million animal species and say "BEHOLD A HUMAN" because they feel love. Something that isn't just a human experience.

The point being that describing a group based solely off a few features or emotions makes the definition too broad to claim that it is what makes that species said species.

Saying humans are humans cause they have no fur would include furless animals. Same with saying love is what defines humanity. Like either you think elephants don't feel love or elephants are human. Your dog doesn't actually love you or your dog is human.

You can't use vague overly broad concepts to define humans as a species. So maybe stop trying to dehumanize people for not feeling the same emotion as you in the same way you do?

The Alchemist by David Teniers the Younger

I saw this whole long thread of people hand-wringing about "anti-intellectuals" on tiktok and how scary it is that they're believing sourceless claims other people on tiktok tell them, because they claim they have the same chance of being correct as anything that "science says."

and said hand-wringers were waxing poetic about the scientific method and replicability and how everything that's published in an academic journal is guaranteed to be true and correct because of a little thing called peer review whereby scientists (naturally a petty and pedantic people) are encouraged to tear each other's conclusions apart.

and I just have to say. if you believe (in the midst of a major replicability crisis amongst scientific journals, no less) that everything published in a scientific journal is de facto factual or trustworthy, and if you believe that peer review of all things is a process that is guaranteed to prevent papers with anything from flaws in experimental design to full-blown fraud from going to print (as if publishers don't have a literal profit motive to publish studies that yield novel, startling conclusions),

then you are 100% as "anti-intellectual," foolish, & averse to thinking for yourself as the tiktokers you're making fun of. actually I think I like you less. at least their ideas might be bizarre enough to be interesting

As I'm studying, I keep finding fascinating tidbits of mining history/mineral processing that I want to write about. Like Tellurium is highly toxic, and even in low doses, (10 ppm), will give people "garlic breath". That's so cool!!! Gold-Tellurium processing is really cool!!!
