Hello! Of all the headlines under which this news came out, the version from Futurism seems to me the most accurate.

Here is the news: "11K SCIENTISTS: PLEASE PANIC, CLIMATE CHANGE WILL KILL US ALL"

This is a very large-scale attempt by scientists from 153 countries to attract the attention of the widest sections of the population.

The problem with climate change is aggravating faster than the saddest forecasts.

What to do? In simple words, everything that they thought of doing before, but not in theory, in practice. These include reducing methane emissions (hello livestock!), reducing greenhouse gas emissions, introducing new energy efficiency methods, birth control (!), and, in a tribute to the times, removing barriers to gender equality.

What is really connected with the fact that the real situation is worse than the worst assumptions? Overconsumption - The wealthiest countries still have the highest per capita greenhouse gas emissions.

The Paris Agreement on climate change didn't help :(

Hello! I followed with enthusiasm the story shared by Denis Shiryaev from the editors of the "Committee" (DTF, TJ) about the composer Antonin Dvorak, who 115 years ago did not finish one of his works "From the Future World", having died prematurely.

Thanks to algorithms and the startup AIVA, the work was completed and the Prague Philharmonia in Prague performed the final part of the piece in November of this year.

Listen to how the piece added by the neural network sounds, only 6 minutes, but it's worth it:https://youtu.be/3LRO4ZgB7Ug

Hello! There is a category of innovation that is difficult to recognize at first glance. An example of a breakthrough in industrial design may well be found in your home. OXO's swivel knife vegetable cutter with large rubber handle was developed in 1990 specifically for people with arthritis as part of an inclusive design, but has become the "new normal" as a result.

Now you can find this type of handle in screwdrivers and other tools.

In 1994, OXO products became part of the Museum of Modern Art (MoMA), but are still on sale - the rating on Amazon is kept at 4.8 out of 5 points at a price of $10

Hello! Pictured is comet 2I/Borisov against the background of a distant spiral galaxy. The picture was taken from the Hubble telescope on November 16, 2019, which in the coming days will pass at a minimum distance from the Earth - 289.8 million kilometers. And then it will fly away forever - its speed is too high, more than 32 kilometers per second.

Its path is similar to a straight line, rather than the ellipse characteristic of comets. It is impossible to establish where 2I/Borisov came from, there are too many factors.

The cloud of dust that surrounds the comet will stretch for 160,000 kilometers. Judging by the change in the spectrum, the comet is composed of cyanide and carbon.

The fact that the comet has been detected gives hope that "giant" telescopes under construction (such as the LSST "Large Synoptic Survey Telescope") will be able to see where it went, but this will happen as early as 2022.

To catch up with a comet that moves at such a speed, humanity can not yet.

Hello!
No, these are not the results of a year or a decade.

Just look at what news the subscribers of this channel expected in 2019 and compare with your feelings :)

I won't bore you with a long message, Happy Holidays! Thanks for reading. I hope I can write for the channel more often. Inspiration and hope in 2020! ⚡️

Hello! The first publication this year will be with a very "catchy" title - a new theory about the construction of a time machine has appeared.

Its author is astrophysicist Ron Mallett, professor of physics at the University of Connecticut (USA). In an interview with CNN, he announced the existence of a scientific equation that could serve as the basis for a real time machine.

Before getting acquainted in more detail, let's clarify right away that this is not about traveling to the future, by accelerating a rocket with an astronaut to near-light speeds.

Malett believes that travel to the past is possible by combining two theories - general relativity (the curvature of space-time under strong gravity) and a laser loop - a theoretical "ring laser" that creates a circulating beam of light.

In any case, even if this theory is confirmed in the future, it does not solve the problem of "physical" movement into the past - the effect created in this way may allow information to be transmitted to the past, but only to the same point in space where the "laser" will be created. the loop".

A detailed CNN interview, including a short biography and criticism from other scientists, can be read here in English: https://edition.cnn.com/travel/article/time-travel-ron-mallett-scn/index.html

Hello! Right now, from space, you can observe the consequences of the fires in Australia.

Raging forest fires paint the entire (!) Continent in blood red hues.

See what it looks like from Japan's Himawari-8 meteorological satellite.

Australia's wildfires are so big that they spawn their own kind of firestorm, the 'pyrocumulonimbus', which is capable of causing even more fires.

Clouds of smoke rise to a height of 16 kilometers, creating thunderstorms (lightning causes new fires), carrying embers from existing fires and intensifying fires due to accompanying wind currents.

In particularly severe cases, pressure differences between areas with pyrocumulonimbus and normal weather can cause fire tornadoes.

Smoke emissions in such cases can rise to a height of more than 30 miles (48 kilometers).

Hello! A recent genetic experiment has given rise to a new round of publications about a cardinal life extension. Geneticists use nematode worms Caenorhabditis elegans for experiments.

They live only 2-3 weeks, and their body is very simple - ideal candidates for experiments.

The essence of the "mutation", or rather changes in the genes, was to suppress the work of the genes responsible for growth and metabolism - by disrupting pathways in mitochondria and slowing down protein synthesis.

In a new work that combines two methods of prolonging the life of experimental subjects, it was possible to extend the life of the worm by 500% - the mutation acts synergistically, enhancing the effect.

How can you describe the essence in simple words? Animals that suppress the synthesis of a particular protein receive less of it. But if at the same time the mitochondria lack substrates that help to get more energy, they make the surrounding cells more responsive to stress. And live longer.

Hello! This is what the solar photosphere looks like.

The largest ground-based telescope DKIST (Daniel K. Inouye Solar Telescope) photographed an area measuring 36500x36500 kilometers.

The images show that the hotter plasma rises from the center of the granule and then expands down the edges. And the luminous "cracks" are the exits of the magnetic field from the deeper layers of our star.

Hello! Melanin extracted from the fungus Cryptococcus neoformans was delivered to the International Space Station. It would seem, so what? But the fact is that Cryptococcus neoformans is a type of mushroom that grows in the Exclusion Zone of the Chernobyl nuclear power plant. They contain a huge amount of melanin (a pigment that makes human skin darker), which is used to absorb radiation and convert it into chemical energy. Discovered in 1991, and detailed in a 2007 Johns Hopkins University publication, the mushrooms from Chernobyl, if successful, could protect astronauts in space from exposure to radiation. The results are expected to be available within a few months. We wait!

Hello! SpaceX Crew Dragon brings astronauts to the ISS for the first time!

What's happening?
Today, NASA and SpaceX are opening a new chapter in the history of American and global astronautics - the first manned launch of the American private spacecraft Crew Dragon of the Demo-2 mission with two astronauts on board is due tonight.

The spacecraft and rocket (first stage) are designed for reusable use. The first stage of the rocket after completing the main task will have to board the barge "Of Course I Still Love You" ("Of Course, I still love you") in the Atlantic Ocean.

According to GMT + 2, the launch will take place at 23:33, and you can follow this event online here: https://youtu.be/rjb9FdVdX5I

If you can watch the launch today, don't miss the ISS docking scheduled for May 28 at 18:29

The Crew Dragon crew will spend 30 to 119 days at the station. After completing work on the ISS, astronauts Douglas Hurley and Robert Behnken, along with the cargo to be returned, will return to Earth, splashing down with the help of parachutes in the Atlantic Ocean, near Florida, after which they will be picked up by the rescue ship Go Navigator.

UPD: The launch of Crew Dragon to the ISS was canceled due to weather conditions 16 minutes before launch

Hello!
Attempt number 2 - the weather on the launch pad is good, which means Crew Dragon has every chance to take off in 45 minutes.

The launch was successful! We are waiting for the broadcast of the docking with the ISS tomorrow evening

Hello! Today, NASA on the Atlas V 541 rocket sent another rover to Mars - Perseverance (Perseverance). The rocket was launched from the SLC-41 launch pad at Cape Canaveral. To help the Perseverance rover search for traces of ancient life on Mars will be an unmanned helicopter Ingeniti (Ingenuity, "Ingenuity"). The helicopter-drone is the first attempt to make "controlled flight" in the atmosphere of another planet, except for the landing of rockets. Launching a helicopter in a rarefied atmosphere draws additional attention to the rover's satellite. Official NASA stream with the launch still on the air: https://youtu.be/21X5lGlDOfg

Hello! Anatomy - an established science where you should not expect discoveries? But no - it turns out that new organs in the human body are opened with enviable regularity.

The article on Medusa, in the "history" section, introduces the discoveries of the anatomy of the 21st century - an unknown salivary gland, the lymphatic system in the brain, and even a ligament in the knee "lost" since 1879.

Hello! A detailed story about the closure of Arecibo was published on Habré. One of the largest, and perhaps the most famous radio telescope in the world, is permanently disabled and will be dismantled:
https://habr.com/ru/post/529180/

Hello! The previous news failed to become a reality.

The Arecibo radio telescope was not closed - it collapsed. A massive 900-ton mobile platform with irradiators, suspended on cables, collapsed on a spherical reflector with a diameter of 305 meters, located in a karst funnel.

The collapse of the platform also destroyed the tops of the three support towers surrounding Arecibo, to which were connected the cables holding the platform in the air.

The process of destruction on video: https://youtu.be/ssHkMWcGat4

Hello! In the photo - "nuggets" from chicken meat, during the production of which not a single chicken was harmed. Singapore Food Agency approved the sale of chicken meat by the American company Eat Just - to produce artificial meat, the company's specialists took chicken cells by biopsy and then cultivated them in bioreactors, combining them with a proprietary mixture of proteins, amino acids, minerals, sugars, salts and other nutrients. substances.

The original cells come from chicken muscle cells, and the nutrients added to the reactor come from plants. Now the volume of the "bioreactor" is 1,200 liters, and in order to provide all of Singapore with artificial meat and bring it to markets, the volume of reactors needs to be increased to 10 or 50 thousand liters.

How much such meat costs? Amount definitely cannot be compared with another analog - artificial meat for a burger, in favor of "chicken". The base cost of whey-free "meat" growing medium and its vegetable analogs is about three dollars per liter.
