Nuclear battery - radioactive nickel encased in diamond

Lasts for decades. Weak radiation needs no shielding. Byproduct is copper. 

Weird sandwich

This combination sounds wild, but peanut butter, Miracle Whip, pickles, and bacon makes the ultimate sweet, salty, tangy, and crunchy bite.

Automated mosquito-killer drone - no chemicals, no by-catch of helpful insects.

https://www.facebook.com/share/r/18wfvSKwre/

Tiny 40g drone finds and kills mosquitoes using ultrasound, self-charges, and flies autonomously.

A startup developing autonomous micro-drones designed to hunt and eliminate mosquitoes in mid-air using artificial intelligence and ultrasonic sonar...acoustic detection and kinetic interception: Using a spectrogram analysis, the drone's system can listen for the specific acoustic "fingerprint" of mosquito wings flapping, to differentiate between a dangerous mosquito and beneficial insects like flies or wasps. Once ID'd, the drone's intelligent control algorithms guide it to intercept the pest in mid-air and knock it down using its propellers.

Earth erosion

Very clear animation of the earth erosion formations at Omak near the Grand Coulee dam in WA State. 

Place sliced white mushrooms in the sun.

Exposing white button mushrooms to direct sunlight for 15 to 30 minutes significantly increases their Vitamin D content. This happens because they contain a plant sterol called ergosterol, which naturally converts into Vitamin D2 when hit by ultraviolet (UVB) rays—the exact same process our own skin uses to produce Vitamin D.

Place the mushrooms with the gills (the ribbed underside of the cap) facing upward directly toward the sun. Because Vitamin D is heat-stable, these "sunbathed" mushrooms will retain their enhanced nutritional value even after being cooked or dried for up to a year.

C. S. Lewis on love in marriage

It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by the grace which both partners ask, and receive from God.

Voice like chocolate and nicotine

He has a wonderful sonorous speaking voice ("chocolate stained with nicotine" is how Rachelle's sister Naomi described it)

How AI "thinks"

https://youtu.be/rKV5JcALQoQ?is=xuurxSp6FK869raH

Peeking under the hood of AI reasoning, words that the model is "thinking about" but not actually saying are important to achieving results; eliminating the ability to use such intermediate words in the process made some prompts impossible for it to answer. 

When AI was fabricating results, these inner words in the "J-space" indicated the model knew it was fabricating. 

Soldiers use silly string to detect fine-wire booby traps.

Unsinkable metal

Tiny groves on the surface and a hydrophobic coating make these tubes, of 6:33 a very specific diameter, unsinkable. 

Predatory loan takeovers forcing foreclosure

Predatory bankers take over loans that homeowners thought were forgiven, making 30-fold profits and devastating people's personal finances. 

World-record longest drone flight

It takes a lot of 3D printing, tinkering, and innovation to get a some to fly for over 4 hours. 

Is court evidence accurate?

https://youtu.be/mvcesPWvUIc?is=2deKEEPcEvXFxSPQ

When you actually subject court-approved evidence to the test, to scientific method, most methods are woefully inaccurate. 

Modular homes - barriers to adoption

https://youtu.be/2pbYafEcsbk?is=GLZ8aOzsr9Hqte_F

The broken system of "stick-built," on-site construction is favored by regulation, permitting, banks and neighbors. Changing that to the modular-friendly process popular in Sweden and China is going to take a long time. 

21:43 "But if we really could build homes and apartment buildings 20 to 30% cheaper, twice as fast, make them more environmentally friendly, and make them with better materials then maybe, just maybe, one day, we could address this housing shortage"

Horses rebuild after desertification

https://youtu.be/Hl8vErrqjKY?is=nO5pfnHNYYIOS4k_

Start at 9:00. Horses selectively trample bare ground, not the grasses they eat. Seeds in their dung germinate better after traveling through their gut, essentially providing a 11:20 "self-watering, pre-fertilized seed packet." Nitrogen levels rose, insects, then birds, and then predators started to return. 

21:25 China had planted 66 billion trees in a failed attempt to thwart desertification, but 21:58 grasslands require 90% less water than trees. 

By 2023, a desert that was 23:27 expanding by thousands of km² per year was now shrinking by 47 km² per year.
