Which fish not to eat ?
Catching several fish, hook or trap or spear... Is there a test to check if this, that or the other species is 'not edible/poisonous' ? Is it the same story as mushrooms, relying on someone else experience/knowledge ? Is there a 'poison tell tale" test ? If a laboratory test is the way, what does the test looks for ? -Move to another section if deserved-

Results of blood tests...
Greetings. If a person with excellent diet habits, a stable and very good health indicators gets a blood test just after an unusual 'festive-abusive' diet day; like excess of salt, or sugar, or alcohol, or lipids, or whatever; do results reflect the test as if was a 'normal' state or there is something in the results that shows being a recent anomaly spike or is it indistinguishable ? In other words; can an adverse blood test be a result of a very recent 'abuse' and not normal for the patient, to supposedly return to 'normals' in a few days ?

Can anyone explain as for a child, please ?
Hello all. To fill a concept void, can anyone do a superb explanation if/how one measures mass and the other weight ? -Or not-

- Extracting water with metal-organic frameworks...
---> https://www.electricaltechnology.org/2026/02/nobel-chemist-turns-air-into-water.html At the heart of the technology are advanced materials known as Metal-Organic Frameworks (MOFs). These specially engineered materials contain billions of microscopic pores that can capture water molecules from the air. Despite weighing only a few grams, MOFs have an enormous internal surface area, allowing them to absorb significant amounts of moisture. Imagine producing clean drinking water straight from the air, even in some of the driest places on Earth. That vision is becoming a reality thanks to a groundbreaking invention developed by a Nobel Prize-winning scientist. As air moves through the machine, the MOFs trap water vapour. When exposed to sunlight or low levels of heat, the materials release the captured moisture, which is then condensed into clean liquid water. Unlike many traditional atmospheric water generators, the system does not rely on energy-hungry cooling equipment. Instead, it operates using solar heat, making it suitable for off-grid locations. The invention is based on a branch of chemistry known as reticular chemistry, a field pioneered by Yaghi himself. The technology can reportedly work even in environments where humidity levels fall below 20 per cent, opening up possibilities for arid regions where water is scarce More at: https://economictimes.indiatimes.com/news/new-updates/no-rivers-no-wells-no-rain-needed-how-a-nobel-prize-winning-scientists-invention-produces-up-to-1000-litres-of-drinking-water-daily-from-thin-air/articleshow/131485522.cms?utm_source=contentofinterest&utm_medium=text&utm_campaign=cppst- Extracting water with metal-organic frameworks...

Fourth release of classified files from ---> https://www.war.gov/UFO/- Another energy storage system
If you are not near a mountain you will have much, much less wind as source in the lowlands for storing energy. If there is no height, would be like putting solar collectors in the shaded slope of a mountain. Things are done at locations where deserve being done, even with transmission lines from generation to consumption. As there is no solar generation in the Sahara, with no consumption there.- Another energy storage system
It would be much more simple to raise the weights to a mountain slope than constructing a tower/building to support them.- Could aliens ever visit Earth?
