OXYGEN
If your future self could send you one sentence, what do you hope it would say? The level of deforestation we done in 10 years in the name of so called development like developed countries. We lost our consciousness about environment and one day we died due to lack of oxygen and before died i will say OXYGEN. -
Как мы обвязали скриптами четыре рутинных процесса в облачной инфраструктуре
Повторяющиеся операции в облачной инфраструктуре — по отдельности совсем не сложные. Проверить доступные мощности, сверить параметры нового объекта, собрать данные об инциденте или рассчитать лимит IOPS — все это можно сделать вручную. Но когда количество кластеров, площадок, клиентов и запросов растет, а количество рук — не увеличивается, это становится проблемой. Меня зовут Дмитрий, я руководитель службы поддержки виртуальной инфраструктуры в OXYGEN . В этой статье я рассказываю про личный опыт автоматизации мониторинга облака. Под катом разберу четыре задачи, которые мы последовательно автоматизировали — заглядывайте, если интересно.

"Corals Spin Tiny Vortices to Get Oxygen, but Not if It’s Too Hot
At first glance, corals present as little more than colorful rocks — piles of lobes, stalagmites, and branches poking out from the seafloor.
They are anything but. Corals are complex creatures that form enduring colonies, and just like other animals they need oxygen to live. Across the living surface of coral, a frantic dance of survival takes place, invisible to our eyes and unknown to science before 2014. The tiny dancers are hairlike cilia, and new research into these microscopic structures is revealing just how active corals are in determining their own fate.
Corals aren’t fortunate enough to have a consistent supply of oxygen, and they can’t change location to seek it out. During the day, the tiny polyps that make up a coral colony get plenty of oxygen from the symbiotic algae that photosynthesize within their tissues. But at night that process stops, and a coral polyp’s only source of oxygen is the water around it. Then it’s do or die for the cilia. Using mechanisms scientists are still trying to understand, the cilia wave around to generate fast-moving vortices of water that circulate oxygen to the coral’s outer tissues, in addition to helping keep the colonies free of sediment.
A study published in Science (opens a new tab) in May 2026 provides new insight into how organisms with no brain or musculoskeletal system can generate and regulate this process — and what happens when the water around them warms up. Warmer water naturally carries less oxygen, which prompts corals to move their cilia faster and faster, as if gasping for breath. Above a certain temperature, the system starts to work against itself; the furious beating of cilia uses up any oxygen the coral’s tissues can absorb, and then the polyps can suffocate in the less oxygenated water. Biophysicists, marine biologists, mathematicians, and modelers are now collaborating to better understand the physiological and hydrodynamic forces at work, and how they correlate with bleaching patterns, coral disease, and mass die-offs."

💁🏻♀️ TIL: 🏔️🐭 Researchers collected 167 Andean leaf-eared #mice from sea level to the #volcano summits of the central #Andes, over 6,700 meters up, then exposed them to simulated thin air in the lab.
The highland mice turned out to use #oxygen more efficiently in their skeletal #muscle and generate more body heat than their lowland relatives. Genome sequencing also showed adaptations for detoxifying toxins in the very #plants they eat.

Как мы за месяц собрали VDI на российском софте для работы с тяжелой 3D-графикой
Привет, Хабр! Из этой статьи вы узнаете, как делить видеокарты от NVIDIA с использованием российского софта, почему полгода тестов не гарантируют успех в развертывании VDI, если надо быстро и по-другому, а также какой протокол все-таки смог «поднять второй монитор», который никак не хотел подключаться. Под катом – все технические подробности и пласт опыта, который мы получили, решая задачу: предоставить инженерам-конструкторам удаленный доступ к тяжелой 3D-графике на импортозамещенном оборудовании и программном обеспечении по выделенному каналу.

SEND IN THE BOTS 💎
Sending robots to the #Moon instead of human beings may be the first genuinely sensible step in the new space race.
#Robots do not need #oxygen, food, #sleep, toilets, radiation shielding or a return ticket.
They can build, explore, test equipment and prepare the ground without risking lives or spending billions keeping a fragile #human body alive in a place entirely hostile to it.
And the experience does not have to belong only to a few #astronauts.
With AI, robotics and virtual reality, millions of #people will #explore the Moon through the eyes and hands of machines.
You could stand on the #lunar surface from your own home.
Look back at the Earth in real time.
Walk through a crater.
Help direct an experiment.
The great benefit of space technology may not be sending more bodies into #space.
It may be allowing everybody to experience space without leaving Earth.
Send the bots.
Bring #humanity along virtually.

Very Small Ocean Flyers
I’ve made a flyer out of what I’ve been sending out as postcards so that anyone can print them up and spread the word. Here is the text. You can download them as PNG images below or as PNGs or PDFs at https://verysmallocean.org/flyer.html :
In 2025, Solar & Clean Power met all demand growth while fossil electricity stayed flat.
Fossil exports in mid-2026 are paralyzed on 4 seas & in Russia, while China rolls out EVs (electric vehicles) & renewables at massive scales.
Climate Victory is Possible
But Climate Change presents a less talked-about problem: the threat to Ocean Oxygen.
Seawater only contains 6-10 mg/kg of molecular oxygen, O2, compared to 210,000 mg/kg in the air.
This is not just about dead zones caused by fertilizer runoff. Oxygen only gets into The Ocean by surface mixing and the photosynthesis that happens in the top 200 meters where light reaches (mostly in shallower depths than that). The deep oceans must be replenished by the Global Thermohaline Circulation, the AMOC (Atlantic Meridional Overturning Circulation) portion of which is weakening. No one knows when it might collapse.
Also, warmer waters can hold less dissolved gases, of which O2 is one. About 91% of excess global heating from greenhouse gas emissions goes into the oceans.
99.8% of the oceans are 5.6 km or less deep. If the Earth were the size of a basketball, that would be about 1/5th the thickness of a sheet of copy paper. About 9% of it is continental shelf, 200 m or less deep. 80% of the atmosphere’s mass is in the troposphere, the lower 6 km (at the poles) to 18 km (in the tropics). The International Space Station (ISS) would be less than 8 mm elevation. — By [email protected]
The Global Thermohaline Circulation is the closest thing the planet has to a heartbeat/bloodstream. It circulates and balances heat in the atmosphere at the same time it is distributing oxygen throughout The Ocean’s depths.
You can print the below images on two sides of one sheet and cut them into 4 flyers per sheet.

Researchers have since studied its heat-resistant #proteins and temperature-dependent #energy system. The #worm survives without sunlight or #oxygen, sustained by deep subsurface #bacteria that may have been isolated for hundreds of millions of years.
