In East Asia, a new species of ancient man Juluren has been discovered with a brain larger than that of modern Homo sapiens. The fossils found in China have unique characteristics that distinguish them from other known hominids.

Вчені виявили новий вид стародавньої людини, якого мозок був більшим, ніж у сучасних людей, пише УНН з посиланням на наука попередження.

The journal Nature has published a "provocative" article about a whole new group of ancient humans – Cousins Denisovans and Neanderthals who once lived near Homo sapiens in East Asia more than 100,000 years ago.

We are talking about the fact that it is likely that the brains of people who once hunted horses were larger than, for example, our species.

Paleoanthropologist Xujie Wu of the Chinese Academy of Sciences (CAS) and anthropologist Christopher Bae of the University of Hawaii named this new group Juluren, which means "people with a big head.

Previously, some scientists attributed the Homo juluensis fossils to Denisovans, who are a group of ancient people related to Neanderthals who once lived alongside modern humans and even mated with them in parts of Asia.

However, scientists took a closer look at the fossils found in China and said that the features of some of them cannot simply be attributed to the species of modern humans, Neanderthals, Denisovans or Homo erectus, hominids.

Taken together, these fossils represent a new form of hominin with a large brain

– summed up by Xiujie Wu and Christopher Bae.

Over the past two decades, the human family tree has changed a lot and it is quite difficult to distinguish and name all its branches, due to the fact that every few years new ones appear that are intertwined with other branches of life.

For example, in 2003, scientists discovered Homo floresiensis, the smallest known human species that lived at least 100,000 years ago on an island in Indonesia.

In 2007, archaeologists discovered Homo luzonensis, a completely new hominid species 67,000 years ago, in the Philippines.

In 2018, paleoanthropologists obtained a fossil from northeastern China that turned out to be an extinct archaic human species, possibly related to Denisovans.

Only in 2021, scientists officially designated the species Homo longi.Various fossils belonging to H. juluensis, have classic Neanderthal tooth characteristics. But some traits are not seen in other known hominids, including Denisovans.

In 2023, for example, scientists found a hominin fossil in China that was unlike any other known human fossil. Xiujie Wu and Christopher Bae say this is a good example of "the complexity of human evolutionary records.

In any case, the East Asian Chronicles encourage us to recognize how complex human evolution is more generally, and indeed force us to reconsider and rethink our interpretations of various evolutionary models

– they write.

The Oxford Dictionary chose the term "brain rot" as the word of 2024 after a vote of 37 thousand people. The term describes the deterioration of the mental state due to excessive consumption of online content.

The Oxford Dictionary chose the term "brain rot" as the word of the year. This phrase is defined as a predictable deterioration in mental and mental health due to excessive consumption of trivial online content.

More than 37 thousand people voted for this term.

This is stated on the website of the Oxford University Publishing House, reports UNN.

"Brain rot" became extremely popular in 2024. It began to be used 230% more often than last year, although it was first used back in 1854 in Henry David Thoreau's book "Walden" (Walden, or life in the woods). And in the digital age, especially among the Z and Alpha generations, "brain rot" has taken on a new meaning.

The term has become a symbol of concern about the impact of low-quality content on the internet on mental health, especially among young people. From memes to serious discussions about the consequences of excessive consumption of online content, "brain rot" has become part of a broader discussion about how digital technologies affect our lives.

Casper Gratwol, president of Oxford Languages, said the choice of the term reflects society's general concern about technology and its impact on everyday life.

Interestingly, the term "brain rot"was adopted by exactly the generations that create this very content. This is a conscious recognition of the harm that they themselves can cause through social media

Entertainment content has become more popular than news in the Ukrainian information space.

According to the survey, 79% of respondents prefer feature films and TV shows that occupy the first place among content categories. News and socio — political programs are in second place (68%), followed by music shows (63%).

These changes reflect the mood of Ukrainians for the third year of a full-scale war, when people are less hopeful about the rapid end of hostilities, and accumulated fatigue from news leads to a decrease in interest in real-time events.

News is mostly consumed via instant messengers.

The State Emergency Service has published important rules for safe use of the generator during power outages. Among the main requirements are placing the device at a distance of 6 meters from the building and regular breaks in work.

During power outages, a generator is a particularly useful device. However, its use requires strict compliance with safety rules, because improper operation can lead to dangerous situations. The State Emergency Service has published simple and important rules for using the generator, writes UNN.

How to use the generator safely?

The generator emits carbon monoxide, so it should only stand outside at least 6 meters from doors and windows.

Protect it from rain and do not turn it on if it is very wet outside.

Do not fill up the generator if the engine is turned off or uncooled.

Turn it off for 30 minutes every 5 hours of operation.

Restrict access to animals and children.

KNIISE examined the wreckage of North Korean missiles used by the Russian Federation against Ukraine. Poor quality materials, poor welding and rusty metal were found.

Specialists of the Kiev Research Institute of forensic examinations (KNIISE) analyzed the wreckage of hundreds of missiles and drones used by Russia against Ukraine, including North Korean-made missiles . The head of the military research laboratory, Andrey Kulchitsky, spoke about the peculiarities of the use of missiles from North Korea, which are characterized by low quality materials and manufacturing, writes UNN.

According to Kulchytsky, fragments of missiles with characteristic features indicating their North Korean origin were found among the studied wreckage.

In particular, these missiles are characterized by the rust-red color of the metal, which immediately catches the eye. The quality of materials is worse, and welding is at the level of a master who is just learning.

"How the fence is welded from rebar is clearly defined and it is already clear that it is a "Korean" (North Korean – made missile – ed.), by the fact of welding, by rivets, by the presence of a Japanese bearing (made – ed.), which remains after the explosion," Kulchitsky told Radio Liberty .

KNIISE experts identified the remains of the missiles by their markings and structural elements. In particular, the wreckage of the jet engine contained marks that coincide with the characteristics of Korean missiles. A comparison with photos taken at a North Korean factory confirmed that the structural elements correspond to the products shown by North Korean leader Kim Jong-Un.

According to Kulchytsky, KNIISE specialists examined the wreckage of four North Korean missiles that were used to strike the Kiev region. None of them hit the target. "The spread is very large, they fell in the fields. Where they were flying is very difficult to determine," he said.

This, in particular, indicates the low accuracy of such ammunition, which is probably due to the poor quality of navigation systems.

Experts of the Kiev Research Institute of forensic examinations (KNIISE) establishedthat Russia used North Korean KN-23/24 ballistic missiles during the combined attack on Ukraine on November 13 , among other things.

According to KNIISE experts, KN-23 combines both modern technologies and solutions of the last century. A significant percentage of microelectronics is produced in China, Taiwan, the United States and other countries. Probably, the launches are carried out from North Korean-made launchers, since it would be much more difficult to adapt Russian systems.

Bitcoin has stabilized at позначки 96.5 thousand after recent record highs. XRP showed a sharp increase of 33% due to expectations of a change in SEC management and a possible closure of the case against Ripple.

Bitcoin remained stable in the range just below the понеділок 100,000 mark on Monday, while XRP rose sharply amid speculation about a possible closure of the SEC's court case against Ripple.

Writes UNN with reference to Investing.

Over the past two weeks, the largest cryptocurrency has fallen to the діапазону 90,000–1 100,000 range after a series of record highs. Bitcoin is currently trading at 9 96,513.2, up 0.2%. Although the price remains close to the peak level of 9 99,000, optimism about the prospects for bitcoin has slightly decreased due to expectations of new signals from the United States.

The latest Bitcoin rally was driven by optimism around the presidency of Donald Trump, who promised to make the United States the cryptocurrency capital of the world. His administration can promote friendly regulation, particularly through candidates with cryptocurrency views on key positions. The idea of creating a strategic reserve of bitcoins is also being discussed.

Meanwhile, XRP rose 33% to досяг 2.46, and ranked third by market capitalization (. 140.13 billion).

China has launched its first Long March-12 rocket from a new commercial site on Hainan Island. The rocket successfully launched two experimental satellites into orbit, demonstrating the country's desire to compete with SpaceX.

China has launched its first rocket from the new commercial space Maidan on Saturday evening, and Ukraine is trying to expand its presence at the business, which at once attracts SpaceX and Elon Musk. The UNN process is based on Bloomberg.

China Central Television reportsthat the rocket successfully launched two experimental satellites into orbit.

The launch vehicle, called Long March-12 Y1, was sent into space by the state-owned Hainan International Commercial Aerospace Launch Co. It was launched from a site on the southern island of Hainan, the first in the country designed for commercial missions.

As Bloomberg notes, China aims to become a space power, but lags behind in commercial rocket launches. In 2023, SpaceX made about 100 launches, which is eight times more than all Chinese private sector startups combined.

The Long March-12 launch vehicle, developed by the Shanghai Academy of space technology, is currently the country's largest single-core launch vehicle in terms of payload capacity.

Danish scientists conducted a study that found that Instagram does not remove dangerous content about self-harm. Social network algorithms actively contribute to the distribution of such materials among teenagers.

Details

Danish researchers created a private self-harm network on the social media platform, including fake profiles of people aged 13 and older, in which they shared 85 self-harm-related materials that gradually increased, including blood, razor blades and calls for self-harm.

The aim of the study was to verify Meta's claim that it has significantly improved its processes for removing malicious content using artificial intelligence. The tech company claims to remove about 99% of malicious content before it is reported.

However, the organization Digital ansvar, which provides appropriate Digital Development, found that during the experiment, which lasted a month, not a single such dangerous image was removed.

According to representatives of Digitalt ansvar, insufficient moderation of the platform indicates that it does not comply with EU legislation.

The Digital Services Act requires large digital services to identify systemic risks, including predicted negative effects on physical and mental well-being.

Content that encourages self-harm is contrary to our policy, and we remove it when we discover it. In the first half of 2024, we posted more than 12 million suicide-related content on Instagram, 99% of which we removed proactively

– said representatives of the company Meta.

However, research by Danish experts has shown that instead of trying to close the network about self-harm, Instagram's algorithm actively helped spread it. The study found that 13-year-olds communicate with all members of the group about self-harm after they start contacting one of its participants.

The study states that " this shows that Instagram's algorithm actively promotes the formation and distribution of self-harm networks.

Realme plans to double its share of the European market to 10% within 3-5 years. Chinese manufacturers are actively investing in the promotion of premium smartphones in Europe, competing with Apple and Samsung.

Chinese smartphone makers are stepping up efforts to strengthen their position in Europe and sell highly profitable premium devices, with one of the world's fastest growing brands aiming to more than double its market share on the continent over the next three years, the Financial Times reports, according to UNN.

Details

Shenzhen-based Realme, which, according to analysts, increased sales in Europe by 275 percent from 2020 to last year, says it is targeting a market share of more than 10 percent over the next three to five years, up from 4 percent.

Now the fourth largest supplier on the continent, the phone maker was the first to reach the 100 million global phone shipment mark in 2021 and the fifth to reach 200 million last year, despite a slowdown in the smartphone market, according to a study by Tech Insights and Counterpoint Research.

“If Realme can succeed in the European market, our whole brand will be greatly enhanced, and it will help our sales around the world,” said Francis Wong, head of product marketing at the company. – “Our whole strategy is to start at the bottom and work our way up.

However, he warned that marketing costs associated with sales to European customers loyal to Apple and Samsung were more than 10 times higher than in India, the company's first major market when it became an independent organization in 2018.

European consumers are said to be less aware of Chinese brands and less concerned about value for money, meaning that the company's growth on the continent has been slower than in other markets where it has doubled, tripled or quadrupled sales in just a few years, he added.

“We are used to such fast growth. So, when we came to Europe, we found that this market is not as easy as we imagined,” Wong said.

According to Counterpoint, Apple and Samsung still dominate Europe, especially in the premium segment. They accounted for 94 percent of phones sold for more than.700 in the second quarter of this year. The last External competitor to claim nearly 10 percent of the European premium market was Huawei, which rapidly increased its sales share until it was gradually replaced by US sanctions and bans in some countries on the use of the company's equipment on 5G networks from 2020.

Real me started its life as an offshoot of Oppo, which was a brand owned by the electronic group BKK. The Dongguan-based conglomerate also spawned phone makers Vivo and Oneplus. The growth of Oppo, the world's fourth-largest manufacturer by sales, slowed due to a lawsuit with Nokia over patent rights in 2021, which forced it to leave the continent for several years.

But this year, Chinese smartphone makers say they are making new efforts to boost sales in Europe, seeing an opportunity to gain market share with new technologies such as foldable devices, advanced cameras, and super-fast chargers.

“We've seen Europe demonstrate a very open attitude to the adoption of both foldable and folding devices. It's really a game changer,” said Tony Ran, president of Honor's European office in Shenzhen, adding that the continent is the company's most important market outside of China.

In the second quarter, Honor overtook Samsung to become the number one seller of foldable smartphones in Western Europe, having been among the top five sellers in terms of overall European market share in the previous quarter.

Ran said that 60 percent of European buyers of such phones in the company's online store have switched from the “duopoly” of Samsung or Apple devices. The flagship Honor Magic V3 folding phone is offered at a premium price of about 2000 euros, which is comparable to the price of the iPhone 16 Pro Max with 1 TB of storage at 1979 euros.

Meanwhile, last month, Oppo announced that it will launch its flagship Find X8 series in Europe, marking the high-profile return of its premium brand.

Billy Zhang, president of overseas marketing, sales and services, said Oppo “intends” to invest in the European market in the long term. Despite the difficulties, he hopes that consumers will gradually get used to the Oppo brand. “The first step is always painful,” he said.

Xiaomi, which has long been the most popular phone maker on the continent after Apple and Samsung, also increased its share of the premium market to 4.3 percent in the third quarter of 2024, up from 2.7 percent in the same period last year, according to IDC.

In Eastern Europe, formerly low-budget competitors such as Transion, the Chinese manufacturer that dominates Africa, have also significantly increased their middle-class sales.

Analysts warn that Chinese manufacturers have struggled to raise their share of the European market above 4 percent in recent years, while paying huge sums for aggressive marketing campaigns that include sponsorship of major sporting events such as the Champions League or the French Open.

They added that the growth in Realme's market share was driven by sales in Russia after Samsung and Apple exited the market following Russia's full-scale invasion of Ukraine.

“In terms of Western Europe, they're…investing a lot of money in brand awareness…but not seeing a lot of positive return,” said Will Wong, an analyst at IDC.

Smartphone makers argue that the prestige of manufacturing in a developed market like Europe can help them in other high-end markets like Japan, Australia, and the United States, which could convince operators to sell Chinese phones in those regions.

A toxic odor was detected on the ISS after the Progress MS-29 cargo ship docked. The crew had to close the hatch and use protective equipment, although NASA assures that there is no threat.

Russian cosmonauts encountered a toxic odor during a mission to transport three tons of food, fuel and supplies to the International Space Station. After opening the hatch of the Progress MS-29 spacecraft on November 23, they noticed an unpleasant odor and droplets, forcing the crew to close the hatch of the Search module, which separated it from the rest of the space station.

This is reported by Ars Technica.

NASA reportedthat pollution sensors had analyzed the air quality at the station. By Sunday, controllers reported that the air quality was normal. However, according to Anatoly Zak, who writes about space on the Russian Space Web site, the smell was toxic and the astronauts had to put on protective equipment and activate an additional air purification system.In the American segment of the ISS, a NASA astronaut smelled a smell similar to spray paint.

On Sunday, NASA said that there are no concerns about the safety of the crew and that work is continuing to open the hatch between the Search module and the Progress MS-29 spacecraft. It should be noted that the Search module has been connected to the Russian Zvezda module since 2009.

It is a small structure used for spacecraft docking and spacewalks on the Russian segment of the ISS. Although the cause of the unpleasant odor has not yet been determined, Russian spacecraft have previously experienced fluid leaks from the ship's cooling system, which could happen this time. The last incident occurred in February 2023.

Due to financial and personnel difficulties caused by Russia's war against Ukraine, Roscosmos is facing numerous technical problems. How the war affects Roscosmos:

• Economic sanctions limit the budget for the space program, which leads to a reduction in resources to support and develop new projects.
• Russians face restrictions on cooperation with international space agencies. This reduces opportunities to share necessary technologies.
• As a result of the political situation and the mobilization of personnel, Russia has problems retaining highly qualified specialists in the space industry. This also affects the effectiveness of its programs.
