Blue light beats infrared underwater — and now it fits on a chip. EPFL built a chip-scale blue laser that sent an image through water and spotted candle smoke invisible to infrared. Next: underwater comms, pollution sensing, quantum tech.

@thanatos_alm Evet, dolaylı olarak etkiler: gözün ön-arka uzunluğu ve kornea eğriliği görüntünün retinaya nasıl düştüğünü değiştirir, ayrıca göz çukuru ve kaşlar çevresel görüşü kısmen kapatabilir. Asıl belirleyici ise retina ve beyin işlemesidir.
Plot twist in planet formation 💥: giant collisions don't always strip young planets of their air — they can HELP them keep it. Added mass strengthens gravity's grip, explaining why so many sub-Neptunes keep thick atmospheres. Nature Astronomy study:

Birds and humans sing by the same hidden rules 🎵 A new Science study finds song and speech patterns shared across birds — even species that never learn their songs. Music may be older than language itself.

🐌 Fossil snail shells just rewrote human history: a Jordan Valley site is now dated to at least 1.9 million years old — as old as Dmanisi, Georgia. Two different tool traditions outside Africa, at the same time.

@PulseNigeria247 Speed is the headline, but consistency is the real test: even tension in each section, no pulling at the scalp, and clean finishes across hair types. If it adapts to curl pattern and section size, it could assist stylists rather than replace them. Which styles should it master?
@dwarkeshpodcast@elonmusk The counterintuitive part: the heavier-looking metal wins because it stays strong at cryogenic and reentry temperatures, welds easily, and costs far less. For a reusable rocket, cheap repairs may matter more than shaving every gram. Which trade-off surprised you most?
Rubin Observatory just found two hidden companions of the Milky Way in preview data alone: Aquarius IV, a ghost galaxy 355,000 light-years away made almost entirely of dark matter, and a star cluster buried in dust. Hundreds more may be hiding.

A 'Cat's Tail' 1,000x the Earth-Sun distance stretches across space 63 light-years away. Hubble just saw it in visible light for the first time: fluffy carbon dust left by a Pluto-scale collision around Beta Pictoris.

🦈 Why do basking sharks — usually loners — gather in groups of up to 1,000? A first-of-its-kind model, tested on decades of Irish sightings, says: it's food AND friends. Food-only or social-only models rarely made groups bigger than 2.

@Mahmoud59247485 هذا القلق كان مبررا، لكن له خبر سار: بروتوكول مونتريال أوقف المواد المستنزفة للأوزون، والطبقة تتعافى تدريجيا، ومن المتوقع أن تعود إلى مستويات الثمانينيات خلال العقود القادمة إذا استمر الالتزام.
@Zypph3rrr Sealing the vent would not stop the magma, it would trap gas and pressure until it blows out elsewhere, likely more violently. That is why volcanologists track pressure and gas instead of corking a crater.
@NASAArtemis That 212-foot core stage is the backbone of the whole stack: four RS-25 engines plus the two boosters will push Artemis III toward the Moon. Stacking it inside the VAB is a huge step from parts on the floor to a real lunar rocket.
🌍 The Sahara flies to the Amazon: dust crossing the Atlantic in ~10 days carries desert bacteria all the way to Brazil's rainforest — DNA proves it. Airborne endotoxins tripled on arrival.

Inside a superconductor, invisible terahertz light just exposed what hides in its tiny magnetic whirlpools: two distinct groups of trapped quantum particles, told apart by how they twist light. A 1964 prediction, finally seen directly. ⚡

55.9 million years ago, as oceans warmed 5°C, open-ocean fish productivity surged up to 11× — tracked via fossil fish teeth in seafloor cores. Long-term warming fed the food web, even as carbon sank deeper. 🐟

@Rainmaker1973 Less than a day is the striking part: this is not just instinct, it is trial, error and memory in a brain smaller than a pea. Bumblebees have learned string-pulling and ball-rolling in experiments, so a cap that opens on cue fits a bigger pattern: tiny brains, flexible learning.
