CES 2019: LG built a waterfall with flexible OLED TV

At previous Consumer Electronics Shows, LG and Samsung built huge scenes with flexible OLED panels. However, when we saw the “waterfall” built by LG at CES 2019, we still couldn't help but be amazed. During the previous year's CES 2017, the company built an OLED tunnel. At CES 2018 last year, the company built another OLED canyon. Clearly, LG hopes to demonstrate the huge potential of flexible OLED panels.

The OLED flexible screen “waterfall” is 65 feet (19.8 meters) wide and 20 feet (6.1 meters) high, using 112 55-inch plain panels and 76 curved + 72 raised panels.

The arched waves create an extremely powerful effect that runs from the top of the head to the floor. In terms of scenes, LG has carefully prepared desert, ocean, waterfall and other rendering modes that display different light, supplemented by natural stereo sound effects.

Although it is unlikely that ordinary people will use such spectacular equipment, at least we show us the future of flexible curved screens. The current screen curvature on the market is relatively small, and LG hopes to apply the new technology to the electronic display panel first.

Most importantly, unlike LCD panels that require backlighting, OLED pixels are self-illuminating. The backlight layer is eliminated, making the device lighter and thinner. In addition, the use of plastic substrates (not glass) makes it easier to bend.

It is worth mentioning that LG Signature OLED TV R will come first, and the TV won the CES 2019 Best TV Product Award from foreign media.

It allows the OLED panel to roll like a garage door, putting a 65-inch device into an inconspicuous enclosure like a sound bar.

LG said the TV will be available in the spring of 2019, when the final price has not yet been announced. The estimated price will not be lower than the five-digit number, but at least much cheaper than the CES 2019 on-site OLED giant screen waterfall.

Researchers hope to find a more appropriate synonym for "feces"

Addra Bhatt is a professor at the University of North Carolina State University (UNC) School of Medicine, where he works on cancer and bacteria, as well as on the interaction between drugs and the gut. Recently, however, she launched a new proposal in the Journal of Gastroenterology, hoping to take a more appropriate synonym for experimental investigations related to feces.

The nature of the work determines that Aadra Bhatt should often deal with feces in order to gain insight into the mysteries. But when she wrote the research report, she was guilty—because it was difficult to find the exact words to describe the experiment.

In real life, people have countless informal names for feces in and out of the body. But in the relevant experiments carried out on test tubes and petri dishes, which words should be used in the final point?

Aadra Bhatt said helplessly: "I have to use multiple phrases to describe specific parts, such as 'the fecal extract of the mouse we studied'. But this is too tiring, so I thought about it. Brand new words."

Given that many of the words in biology came from Latin, Aadra Bhatt decided to start with this and invited structural biologist Matt Redinbo and classic scholar Luca Grillo to help.

Interestingly, they found a lot of words in Latin to describe feces. After various trade-offs, they removed options such as merda or laetamen (feces in the mountains).

In the end, the team chose the fimus, a term that describes human and animal droppings. And the Romans seem to like the word very much, which is particularly literary.

"In Fimo": A Term Proposed for Excrement Examined Experimentally

Five speculations about mysterious space waves: the alien signal is extremely low

According to a report on the BBC website on January 11, humans received mysterious signals from distant galaxies. When a fast radio storm reaches a telescope on Earth, they emit a few milliseconds of light and then disappear. In the past 10 years, astronomers have detected dozens of such signals. They have just announced the discovery of more signals, including rare repetitive fast radio burst signals.

We don't know what they are or where they come from, but there are five suspicious objects here:

A fast-rotating neutron star

When a star explodes and dies, it becomes a fast-rotating neutron star. Astronomers believe that fast-rotating neutron stars found in high magnetic fields may produce such strange signals.

Professor Ingrid Stalls, an astrophysicist at the University of British Columbia in Canada, said: "Things like neutron stars actually fit this condition."

She said: "However, we still don't know what physical phenomena have produced such a huge radio storm."

Two stars being merged

Another possibility is that the two neutron stars are colliding with each other.

Astronomer Shriash Tendukal of McGill University in Canada said that this is one of the mainstream theories, but this theory only applies to cosmic signals that have only appeared once, because the stars are destroyed in the process. .

He said: "This is a radical event and does not apply to recurring fast radio bursts."

In the past ten years or so, most of the fast radio bursts captured by telescopes have only appeared once and then disappeared.

However, it has been found that two elusive signals reappear - there must be a different interpretation of this.

Blitzar star

The Blitzar star is a fast-rotating neutron star that collapses under its own mass to form a black hole.

Again, this ends with the destruction of stars, so it is impossible to produce a repetitive signal.

Black hole

Many theories involve black holes—from neutron stars falling into black holes to black hole collapses or dark matter hitting black holes.

Extraterrestrial life

While some believe that these signals are entirely natural, others speculate that they may be evidence of alien activity.

Styles believes that this possibility is very low.

In an interview with the BBC, she said: "They come from almost every corner of the universe, and the distances are not the same, so they must be related to many different galaxies."

She said: "It is totally unimaginable. There are so many different alien civilizations that decide to send the same signal in the same way. This seems extremely unlikely."

Foreign media: landing on the back of the moon to show the ambition of China's space power

According to foreign media, in October 2018, Neil Armstrong’s biographer, The First Man on the Moon, was filmed by Damian Shazel. The film caused an uproar because it did not show the moment when the Americans put the flag on the moon. When the Americans quarreled for the first person on the moon, China was preparing to launch the No. 4, which successfully landed on the back of the moon on January 3.

Institutional advantage

The US "Washington Post" website published an article on January 10th saying that China's goal is to become the world's leading aerospace power by 2045, and its vision is also very different from the urgent reasons for the US-Soviet competition during the Cold War. The most important thing at the time was to put the flag on the moon and then turn to other gimmicks worth showing off.

The article believes that, in contrast, China is focused on developing permanent space power. Recently, by landing on the back of the moon, China has established an important base for resource development. It takes two to three years for the United States to complete its first robotic mission to the moon. The relative lead in space resources may determine who is the dominant force in the future.

The article said that in the future who can get rich space resources such as water or ice, iron, titanium, platinum and nickel; who can ensure the trade route; who can make space business rules, such as energy propellant and precious metal trading; who will benefit from Military power from industrial strength? Most people think about space exploration; what actually affects the future is space development.

According to the article, China's space strategy involves establishing a lunar industrial infrastructure to enter outer space in a cost-effective manner. The fourth is the first step: demonstrating the ability to communicate, log in, investigate and monitor the location of future industrial and logistics bases. The mission ensured China's access to the resource-rich lunar South Pole and pioneered the ability to develop space resources and industrialize the moon to build solar satellites, exploit rich minerals from the moon and asteroids.

According to the article, it is estimated that the lunar poles contain hundreds of millions of tons of water, enough to fuel the numerous space missions that reach the farthest point in the solar system; enough to explore the resources of the asteroid belt; enough to expand logistics for large-scale industrialization; Enough to develop military logistics in near-Earth space.

According to the article, the competition to be observed is not China’s manned moon landing, but the competition between China’s robotic detectors and NASA’s “Lunar Commercial Carriage Service Plan”, which will determine the Develop comparative advantages in the field of lunar resources.

According to the article, because China has a highly coordinated and disciplined system that can establish and maintain long-term goals, and has a large population and talented people, it occupies favorable conditions for winning space races.

Influence affects the world

The Australian "Dialogue" website published on January 4th, Wendy Whitman Cobb, an associate professor of political science at Cameron University in the United States, entitled "China's landing on the moon will trigger a new round of space competition? The article said that on January 3, China became the first country to land on the back of the moon. Landing on the back of the moon is a technical achievement in itself and an achievement that Russia and the United States have not pursued.

The article said that the No. 4 detector is a symbol of the development and strength of China's space program and is of great significance to the relationship between China and the world's major powers. The impact has been passed to the United States, and the Trump administration is considering space races and space exploration prospects.

The article said that historically, one of the main drivers of US space policy was competition with Russia, especially in the context of the Cold War. If China continues to succeed, will the US find itself in a new round of space competition?

The article said that in addition to manned space flight, the Chinese also carried out such space research activities as the No. 4. Its first lunar probe, the Chang'e-1, entered the lunar orbit in 2007, and in 2013 China's lunar rover achieved its moon landing. China's future plans include the creation of a new space station, a lunar base and the possibility of a Mars sampling return mission.

The article believes that the most striking feature of China's space program is slow and steady, especially compared to the early plans of the United States and Russia. Because China's space program is confidential, it is unclear what capabilities it has. However, China's plan may not be the same as its rivals.

The article said that in terms of military applications, China has also proved extraordinary skills. In 2007, China conducted an anti-satellite test, launching a land-based missile to destroy a failed meteorological satellite. The US Department of Defense pointed out in the Chinese military report in 2018 that China’s military space program is “developing rapidly”.

The article believes that although China has relevant capabilities, the United States has not conducted any substantive cooperation with it for national security considerations. In fact, a US law in 2011 prohibited official contact with Chinese space officials. Does this indicate that the United States and China are entering a new space race?

The article said that the answer is both positive and negative. Some US officials, including the National Space Council Executive Secretary Scott Pace, are cautiously optimistic about the potential of the cooperation and believe that a new round of space competition has not begun. NASA Director Jim Bridsenstein recently met with the head of China's space program during the International Aerospace Congress in Germany and discussed areas of possible cooperation between China and the United States. However, competition is intensifying. The Trump administration has demanded the addition of a new independent service, the space force, on the grounds of threats from China and Russia.

The article believes that in any case, China's space capabilities are rapidly developing and have been reflected in popular culture. In Andy Weir's 2011 novel "Mars Rescue" and later filmed in the same name, NASA turned to China for help in the rescue of troubled astronauts. On the one hand, competition may drive technological progress, as evidenced by the first round of space competition; at the same time, stronger global space exploration capabilities may not only help save the astronauts who are in trouble, but also increase our survival for ourselves. Understanding of the universe. Even if China’s rise heralds a new round of space competition, not all effects are negative.

Destructive mosquito embryo scientists find new ways to control mosquito breeding

American scientists say they have taken an important step toward developing a "mosquito birth control" drug. The drug will curb the spread of malaria and other deadly diseases that kill hundreds of thousands of people each year. According to a report on the British Thomson Reuters Foundation website on January 8, researchers at the University of Arizona said they found a protein unique to female mosquitoes, which is important for the hatching of mosquitoes.

When scientists remove this protein, female mosquitoes produce eggs with imperfect outer shells, causing internal embryos to die. The team said that developing drugs for this protein can reduce the number of mosquitoes without harming beneficial insects such as bees.

Roger Misfeld, head of the university's Department of Chemistry and Biochemistry, told this website on the phone: "This is an important discovery."

He said: "Of course we are excited about this... This avoids the mosquito resistance problem and is more biosafer than other methods."

The World Health Organization says mosquitoes are among the deadliest animals in the world. It warned that the global fight against malaria is stagnation. In 2016, the disease infected approximately 216 million people and caused 445,000 deaths – mainly in sub-Saharan Africa.

The World Health Organization says mosquito-borne diseases and viruses include Zika virus, Chikungunya fever, yellow fever, West Nile virus and dengue fever.

Misfeld said that the current method of controlling mosquitoes has been used for many years and mosquitoes have developed resistance.

Misfeld said that the scientists unexpectedly found that the females tested were no longer fertile in their remaining 2 to 3 weeks of life.

He said: "Once we remove this protein, female mosquitoes can no longer produce hatchable eggs, even if they are fed a lot of blood. So... birth control is an excellent way to describe this method."

He said he hopes the discovery will develop a new generation of pesticides in five years.

Misfeld said the discovery, published in the journal Science Public Library and Biology, makes it easier to reduce the number of mosquitoes during disease outbreaks. But he added that scientists don't want mosquitoes to become extinct because it is a pollinating insect.

He said: "Mosquitoes are part of the ecosystem. I will not eliminate mosquitoes."
