🚨 BREAKING: Scientists just discovered hidden structure in water Not deep inside it… but in the top 4 molecular layers at the surface. For decades, physics simplified water like this: → molecules point “up” or “down” → rough orientation picture → good enough Turns out… that was wrong. The...

Big dawg El Niño coming this summer and fall! This is a bit science-y… but easy I promise. So follow along. You are looking at a vertical cross section of the tropical Pacific Ocean at the Equator with depth downward deep into the ocean. Left side is west near Asia. Right side is east near South America. It’s where we measure El Niño, the king control knob of the climate. One main way we know it’s coming is “subsurface heat”. See the dark red shades moving east under the surface and rising upward? That’s the El Niño developing! El Niño is a build up of hotter than normal water on the surface Eastern Tropical Pacific Ocean. What’s cool (or hot) is that the water comes from the West Tropical Pacific. During cool La Niña years it’s like a piggy bank. The West Pacific hoards and stores the heat near Asia. Then every couple-few years that warm water sloshes back East. It first appears under the surface where we measure it. It surfaces in late spring and El Niño grows in Summer to fall. You can tell by the magnitude of warm subsurface water that this looks like a biggie! So how will it impact us? For one, it typically subdues Atlantic hurricane season. That doesn’t mean no storms - just less active than it would have otherwise been. Also it releases lots of Heat… so it super charges heat waves around the planet and floods too - it all tends to be more immense and intense. And you can bet Earth will experience its hottest days on record coming later 2026 into 2027. El Niño is one of the biggest climate forces on Earth and it has a profound impact on world-wide weather because of all the heat released into the atmosphere from the ocean.

In the first video, people in Donetsk are seen greeting a water tanker. In the second video, during the rain, people try to collect at least a drop of water because the water pipeline from the Siverskyi Donets was destroyed by the Russians. When Donetsk was not occupied by Russia, the city hosted the European Football Championship, as well as concerts by Rihanna and Beyoncé. Now, there is no more running water in the city. According to the schedule, water only appears in taps once every three days, and even then it doesn’t reach every household, so water has to be delivered by tankers, with long queues forming for it. People use plastic bags as toilets, and this filth spreads everywhere. This is happening not only in Donetsk - water is supplied once every two days in a number of other cities, including Mariupol. This is how Russia 'liberated' Donbas. Why is this happening? In the past three and a half years - since Russia launched its full-scale invasion of Ukraine in February 2022 - reservoirs in Donetsk Oblast have significantly dried up. The water supply system from the Siverskyi Donets River was destroyed. The region’s reservoirs and underground water sources are not enough to meet the needs of the population, in part due to the extensive network of coal mines. When the self-proclaimed “DPR” and “LPR” were created in 2014, Ukraine did not cut off this water channel, as it was still supplying water to Mariupol, which remained under Ukrainian control. But at the start of the Russian invasion in February 2022, the situation changed: the Russian army, during its offensive, destroyed a unique hydraulic structure that had supplied the region’s largest cities with water. The Russian authorities decided to build a new canal - the Don–Donbas canal - which was supposed to begin in the Rostov-on-Don area. It soon became clear that the new water pipeline, first of all, could not provide the region with the necessary amount of water, and second, it was built with numerous violations, with a large portion of the budget embezzled during construction. Crimea is also suffering from a water shortage, and the situation is worsening. One of the reasons why Russia is striving to seize southern Ukraine is that it sees this as a way to "solve the water issue" for the occupied territories.

:Scientists Capture the Birth of Water, Atom by AtomFor the first time ever, researchers have directly observed hydrogen and oxygen atoms combining in real time to form tiny nanoscale bubbles of water—essentially witnessing one of chemistry’s most fundamental reactions at the molecular early 2024, a team from Northwestern University unveiled a groundbreaking imaging technique that traps gas molecules inside tiny, honeycomb-shaped nanoreactors sealed by ultra-thin glassy membranes. This innovation allows scientists to observe chemical processes in real time using high-vacuum transmission electron microscopes, something previously impossible for gaseous reactions.The team, led by Professor Vinayak Dravid and including first author Yukun Liu, turned their attention to a century-old puzzle: how palladium—a rare metallic element—acts as a powerful catalyst to rapidly combine hydrogen and oxygen into water As Yukun Liu explained: “It’s a known phenomenon, but it was never fully understood. You really need both direct visualization of the reaction and atomic-level structural analysis to figure out exactly what’s happening.”What they saw was astonishing.Using their nanoreactor platform, the researchers watched hydrogen atoms diffuse into a palladium nanocube, causing its crystal lattice to expand slightly. Then, when oxygen was introduced, the gases reacted at the surface. Suddenly, tiny water bubbles began to nucleate and grow right before their eyes on the palladium surface.“We think it might be the smallest bubble ever formed that has been directly viewed,” said Liu. “It’s not what we were expecting. Luckily, we were recording it—so we could prove to others that we weren’t crazy.” The bubbles were confirmed to be water using electron energy-loss spectroscopy and heating experiments. Remarkably, the reaction occurs efficiently at room temperature, and palladium itself is recyclable—it doesn’t get consumed in the process. The order in which the gases are introduced also plays a key role in the speed of water formation.This direct, atomic-scale observation not only solves a long-standing mystery in catalysis but could also inspire new technologies: from more efficient ways to generate clean water in remote or arid environments to improved hydrogen fuel cells and even systems for producing water in space.What once seemed like “water from thin air” is now literally visible—captured in stunning detail at the nanoscale. This breakthrough highlights how advanced imaging tools are unlocking secrets of matter that have remained hidden for generations.The study was published in the Proceedings of the National Academy of Sciences (PNAS) in 2024.

Apparently, I saw this video online and I decided to share. What this worker is applying is called bitumen, or what many of us know as bituminous coating. Most people think a wall is a solid, impenetrable block, but in reality, it is more like a sponge. Concrete and blocks have microscopic pores that pull water from the earth through a process we call capillary action. This thick black substance is the shield that stops that water from climbing up into the house. It is not about making the wall look good because this part will be buried under the dirt forever. It is about creating a skin that water cannot breathe through. When do you need to do this? The need for this arises because the soil is a very aggressive environment. Water is not your only enemy.. The ground also contains salts and sulfates that want to eat away at the cement. If this moisture finds its way to the steel bars inside the columns, those bars will start to rust. And when steel rusts, it expands, and that expansion is what cracks the concrete from the inside out. This coating is the only thing standing between your foundation and that kind of slow destruction. Thats is why if you see wet patches at the bottom of your walls inside your house, it usually means someone skipped this step or did it poorly during construction. You can apply this anytime you are building parts of a structure that will stay in contact with the ground. It is common in areas where the water table is high or where the soil stays damp for most of the year. This is a one-shot opportunity. Once you backfill the soil, you can never go back to fix it without a lot of expense and a lot of digging. It is about having the foresight to protect the heart of the building while it is still exposed. Please don’t ignore this if you need to. If you ignore it now to save a bit of money, you will be funding the future decay of your own home. I hope this helps.

🚨This is NOT AI… and it’s not a trick. What you’re seeing over Fairbanks, Alaska is real aurora physics and real atmospheric chemistry… working together with precision. A solar blast hit Earth’s magnetic field… Charged particles got funneled straight into the upper atmosphere… And then the chemistry took over. Here’s what’s actually happening at the atomic level: Oxygen atoms get excited by incoming electrons… When they relax, they emit light at specific wavelengths: Green (557.7 nm)… lower altitude oxygen Deep red (630.0 nm)… higher altitude oxygen Nitrogen molecules behave differently: Excited N₂ and N₂⁺ emit pink, magenta, and purple tones… That only shows up when the էնergy input is strong… like during a geomagnetic storm. Those “angel wings” people keep talking about? Not symbolic… not mystical… it’s field-aligned plasma physics. Earth’s magnetic field channels particles into vertical sheets… Those sheets form curtains… And when symmetry lines up, your brain interprets structure. That’s called pattern recognition… not deception. Multiple observers captured the same formation… same time… same region… And identical events have been documented before, including in Tromsø. People call it fake for one reason: It looks too perfect. But this is what happens when solar էնergy… electromagnetic force… and atmospheric chemistry all lock in. No filters. No CGI. No AI. Just God’s creation… written in physics… expressed through chemistry… and revealed in light. #SilentMajoritySpeaks #AStoneGroove

Asked to reflect on navigating a “hellish” public breakup, Perrie acknowledges that she receives criticism for answering questions about it, “[but] I’m like, ‘But it really affected me massively’”: “People are gonna hate me talking about it… I can’t catch a break. If I talk about this, they’re like: ‘Why are you talking about it?!’ But anyway, shut up! Yeah, [it’s my life]. When you go through heartbreak, it is hellish. You can’t eat, you can’t sleep, you feel horrendous. You don’t feel good enough and you feel like you’ve been left for something better, or whatever it is… Then what makes it even worse is, I feel like the world was then looking at me, laughing at me. I felt embarrassed; I felt horrified. I had serious breakdowns. I did. Because it wasn’t just the heartbreak I was dealing with. I was dealing with everybody looking at me, and I felt ridiculed. I just couldn’t cope with it; I hated it. I was breaking down in performances, which isn’t like me at all. I was crying constantly. I think I was depressed… I know that sounds ridiculous! But I think it was this plus this plus this, and everything on top. It was like, I had to be there for the girls; I had to be switched on; I had to power through for Little Mix – but I also just wanted to be left the fuck alone. But I also was getting followed every two seconds and asked about it 24/7, and it was the headlines, it was everywhere, and it was a lot! And this is the thing – when people are like, ‘Stop talking about it!’ I’m like, ‘But it really affected me massively’.”

Most chiral molecules arise from carbons being bonded to 4 different atoms, which are called sterocenters. The makes the molecule have a different mirror image that cannot arise from simple rotation. But, you can have chiral molecules not from stereocenters. You can have chirality that doesn't come from a single point in the molecule. It comes from some global property. The classic example is helicene, which doesn't have any stereocenters, but has chirality because of hits helical structure. This means you cannot capture this molecule with a graph, and thus SMILES or a string representation cannot capture this. Of course natural language comes to the rescue (just say in words if it's left-handed or right-handed helix), but it's an interesting failure mode for viewing molecules as just a graph. Another example of a molecule with helical chirality is DNA. DNA is actually chiral in two ways, which is kind of confusing. It has both helical structure and stereocenters. You won't find the stereocenters ever flipped, but left-handed helical DNA can exist (called Z-DNA). Interestingly, making the flipped stereocenter of DNA could be part of an entire mirror organism (mirror RNA, DNA, AAs, sugars) that would then be potentially invisible to our immune systems. This has been recently proposed as a "mechanism" for how a runaway AI system could cause harm to Earth. I find it to be a pretty tedious and difficult way to cause harm, but it is intellectually cool. Anyway - this came up in a PhD defense and I have a lot of arcane knowledge about this I wanted to dump.

a story about taesan’s new fish, yongyongie 🐠 🐈‍⬛ so, you know that recent video that came out (whatdoor tarot episode) the one that was about my slumps? that was, like… maybe about 3 months ago. around 3 months ago, leehan asked me, “what do you think about picking up a new hobby?” he said that seriously starting a new hobby could be a good way to get out of a slump. so i thought, “hmm… can i even add another hobby right now? i already have quite a lot.” then he suggested raising fish 🤓☝️ and i said no, i said i didn’t want to raise one at first. but then he said he’d set everything up for me, teach me how to feed them, how to change the water, basically everything. he said it would be like giving me an early birthday present, he’d set up the whole fish tank for me. and he really did! he ordered everything himself, and now i’m raising fish in my room guys! 🐈‍⬛ but it is not corydoras, it is a type of fish called Betta. Betta fish are really beautiful. so it’s been three months since i started raising it. but i didn’t say anything about it because i thought, “since it’s a birthday gift i’ll talk about it on my birthday.” so i was supposed to say it today, and donghyunie (leehan) just reminded me about it just now. 🐈‍⬛ i have three-coloured betta fish, and it even has my favorite colors, blue and red, together on it (just like korean flag 🇰🇷) i’ll post a picture on weverse after this. it is really flashy fish, and i gave it a name. when i first saw it i thought, “wow, they kinda look like dragons” so i named the fish yongyongi (yong in korean means dragon). it is about this small, but they look so much like dragons that i named it yongyongi, and i’m taking good care of it. i feed it well, if i drop in just two tiny pellets a day, it comes up and eat them. i give it food, and i’ve also learned how to change the water. so the fish living in this small fish tank. i’ll take a picture of it later and post it too.
