According to reports, on Wednesday, local time, the US Securities and Exchange Commission (SEC) announced that it had postponed its decision on whether to approve the first Bitcoin Exchange Traded Fund (ETF).

According to reports, asset management company VanEck applied for approval of the Bitcoin ETF several years ago, but withdrew its application in September 2019. In December 2020, the company submitted its latest S-1 application.

In mid-March of this year, the SEC confirmed receipt of VanEck's application, and thus opened a 45-day review window.

However, before the 45-day review period is about to end (May 3), that is, on April 28 this year, the SEC issued an order to postpone the decision on whether to approve VanEck’s Bitcoin ETF and extend the 45-day approval period to 90 days , the deadline for approval has been postponed to June 17.

Now, the SEC has once again postponed a decision on the Bitcoin ETF proposed by VanEck, this time to solicit more opinions on whether the product should be allowed to be traded on the open market. Meanwhile, the SEC has set July or even August as the deadline for response.

According to sources familiar with the matter, six companies, including automakers Ford and Nissan, South Korean companies LG and Samsung, and start-ups Britishvolt and InoBat Auto, are negotiating with the United Kingdom on the construction of a giant electric car battery factory. This may help ensure the future safety of the British auto industry.

The British government plans to ban the sale of new fuel vehicles by 2030 and hybrid cars by 2035, which will require the country's automakers to switch to electric vehicles. Mike Hawes, chief executive of the Association of Automobile Manufacturers and Traders, an industry organization, said: "We need giant factories to sustain the long-term development of the British automotive industry."

A spokesperson for the British Ministry of Commerce stated that the government is “committed to building a super factory and will continue to work closely with investors and automakers to advance plans for mass production of batteries in the UK”. British research institutions such as the Battery Innovation Center and the Faraday Institute are all seen as key levers for attracting investment in battery manufacturing.

However, Britain’s efforts face competition from the European Union, which is preparing to introduce large-scale incentive programs to attract battery manufacturers. The British government plans to allocate 500 million pounds (approximately US$700 million) to help finance battery factories, while the European Union has raised 2.9 billion euros (approximately US$3.5 billion) in funding. Countries such as France and Germany have also provided additional funds. To enhance their attractiveness.

According to Transport & Environment, an environmental lobby group, so far, there are 38 planned super factories across Europe, but only Britishvolt's projects in the UK have been publicly disclosed. InoBat Vice Chairman Andy Palmer (Andy Palmer) said: "There is de facto competition between the UK and Europe. Whoever wins the giant factory wins the auto industry."

In the early negotiations with the British government, Ford seemed to be more positive. The company said it is exploring the possibility of producing batteries in the UK and then shipping them to Turkey for use in the electric Transit truck it plans to launch. At the same time, Ford may produce battery module components in the UK and then ship them to Turkey for final processing and installation. Last month, Ford announced plans to establish a battery joint venture with South Korean manufacturer SKI. Ford has not yet determined where to produce the battery in the UK, but it is unlikely to produce it at the company's existing UK plant.

It is reported that Nissan and the British government are negotiating to build a battery factory at the Sunderland manufacturing base, but the success of the negotiations depends on energy costs. The company hopes to cut energy costs to improve the competitiveness of the area where the plant is located.

Our pupils will not only respond to light, they will also reflect human states such as arousal, interest, or mental exhaustion and other states. The US Federal Bureau of Investigation (FBI) even uses pupil dilation to detect whether a person is lying.

Recently, a study conducted in the laboratory of the Georgia Institute of Technology, USA has shown that pupil size is closely related to differences in intelligence of individuals. From tests of reasoning ability, attention and memory, it can be deduced that the larger the diameter of a person's pupil, the higher his IQ. In fact, the scientists also found that between the subjects with the highest and lowest scores on a cognitive test, the difference in pupil size was also very different and could be important. directly to the naked eye.

This surprising association was discovered when studying differences in human brain power during memory tasks. In the past, we used to use pupil dilation to measure a person's mental effort. This view was popularized by psychologist Daniel Kahneman in the 1960s and 1970s. Thus, when researchers discovered that there was a definite relationship between the basic pupil size and intelligence proven, the scientific community still feels that this is not certain of its authenticity.

For the same reason, the researchers decided to come from the US city of Atlanta to recruit more than 500 volunteers from 18 to 35 years old, to conduct a larger study on the relationship between pupil size and intelligence. Initially, they measured the pupil sizes of these subjects with an eye-tracking device. This device can use high-performance cameras and computers to capture reflected light from the pupil and cornea to obtain relevant data.

The scientists measured the participants' pupil sizes by having them stare at a blank computer screen for four minutes and during breaks. During this time, the eye tracker recorded data, allowing the team to calculate each participant's average pupil size.

The fact that pupil size is actually the diameter of the black round hole in the center of the eye is between 2mm and 8mm. The pupil is surrounded by the colored area of the eye - the iris. In addition, because bright light constricts the pupils, the team kept all the subjects in the lab in a steady state of light.

Next, the participants had to complete a series of cognitive tests. These tests are designed to measure "flexible intelligence" (ability to solve new problems through reasoning) and "working memory capacity" (ability to solve problems) through reasoning, remembering information for a short period of time), and "attention control" (the ability to focus in a noisy environment).

For example, in an attention-control test, subjects had to resist looking at the flashing bold asterisks on one side of the computer screen, but had to quickly look in the opposite direction to identify a English letters. Since the letter disappears instantly, even if the participant only briefly glanced at the flashing asterisk, the letter was likely to be missed. Although humans have learned to use peripheral vision to respond to objects they see, and this skill allows us to effectively detect predators or prey, this task requires humans participants ignore the flashing of the asterisks and instead pay full attention to the letters.

The team found that larger pupil size was associated with higher flexible intelligence and attentional control and also had a small correlation with working memory, which gives found that there is a certain relationship between the brain and the eye. Interestingly, pupil size was negatively correlated with age: older participants tended to have smaller and narrower pupils. However, after normalizing for age, the aforementioned correlation between pupil size and cognitive ability persisted.

But why is pupil size related to intelligence? Before answering this question, we need to understand what is going on in our brains. First, the size of the pupil is related to the activity of the Locus coeruleus - a nerve nucleus located in the upper part of the brain stem that has extensive neural connections with other parts of the brain.

Second, Locus coeruleus will secrete Norepinephrine - both a neurotransmitter and a hormone in the brain and body. It can regulate processes such as perception, attention, learning, and memory. In addition, Locus coeruleus helps to keep brain activity in an orderly state, so that different brain regions can work together to accomplish tasks and goals. The dysfunction of Locus coeruleus leads to disruption of the brain's systemic functioning and has been linked to a variety of diseases, including Alzheimer's disease and attention deficit hyperactivity disorder.

In fact, the organization and arrangement of brain activities is so important that the brain must expend most of its energy to maintain normal functioning, even when we do nothing during this period, for example. like just staring at a computer or scrolling through a phone screen for a few minutes.

In addition, it is also hypothesized that people with larger pupils at rest have a stronger ability to regulate brain activity, which is good for cognitive function and brain function at rest. Of course, further studies are needed to explore this possibility and determine why larger pupils are associated with higher intelligence and better attention control. But clearly there are still too many questions and mysteries compared to what we have just discovered.

Win11 appeared so unexpectedly, the first impression I saw was a bit of Apple macOS.

Although I have seen it in Win10X, the centered icon still feels like and hate when it is actually installed in Win11. Countless people used the modification tool to change the dock bar similar to macOS, and now the official gave it. However, this also loses the advantage of the Windows classic mouse blind spot in the lower left corner.

But fortunately, Microsoft gave users the opportunity to choose, one-click to the left , and the familiar taste is back.

In addition to the centering of the taskbar icon, Win11 has introduced many exaggerated rounded corner designs , which are more thorough than the changes in Win10 now.

Even the control panel of the grandfathers learned to be well-behaved in Win11.

Turning to look at the MacBook on the side, except for the window button in the upper left corner, the app can no longer distinguish you from me. Sure enough, the design is the same by different routes, and iOS and Android silently praised them.

Owning its own SuperCharger charging network has always been a major selling point of the electric vehicle brand Tesla. At present, the car factory has installed more than 25,000 charging points around the world.

Some of the V2 charging points have a charging power of 120 to 150kW, and the top V3 charging pile also provides 250kW, and the charging speed alone is better than many competitors.

It seems that Tesla is not satisfied with the 250kW charging power. At the Model S Plaid car delivery party last week, CEO Elon Musk revealed that it will continue to increase the output power of the charging pile from the current maximum of 250kW to 280kW, 300kW and the ultimate goal of 350kW.

Unfortunately, Musk did not further explain whether 350kW can be achieved by upgrading the current V3 charging pile, or whether it will be provided when the next generation V4 charging pile is installed, and he has not given a launch timetable.

The battery voltage of the latest Tesla Model S already supports 450V, which means that it supports a higher charging power than the old version, and can quickly charge for 15 minutes to get a range of about 300 kilometers.

Elon Musk's statement about 350kW charging power has actually been heard as early as the announcement of Cybertruck in 2019. At that time, it was said that this electric Pickup would support a faster charging speed than the 250kW V3 charging pile.

According to reports, Indonesia Bank Governor Perry Warjiyo announced at a virtual seminar that the Bank of Indonesia has banned the country’s financial institutions from using cryptocurrencies as payment tools or other financial service tools.

Perry stated: “According to the Constitution, Indonesian Banking Law and Currency Law, cryptocurrency is not a legal payment tool.”

Now, more and more mainstream investors and companies accept cryptocurrencies such as Bitcoin, and some companies even accept Bitcoin, Dogecoin and other cryptocurrencies as payment methods.

For example, in March this year, the US payment technology company Visa stated that it will allow users to use the encrypted currency USD Coin (USDC for short) to settle transactions on its payment network.

In April of this year, online retailer Newegg announced that the company accepted Dogecoin as an official payment method.

The company's move pushed up the price of Dogecoin. In the same month, WeWork, a shared office space company, stated that it would accept cryptocurrencies such as Bitcoin, Ethereum, USD Coin, and Paxos as payment methods.

In addition, in May of this year, foreign media reported that the US space exploration technology company SpaceX will accept Dogecoin as payment.

According to reports, the company plans to launch the DOGE-1 moon landing mission in the first quarter of next year. The cost of the mission will be paid by Dogecoin.

However, the environmental issues caused by cryptocurrency mining have also raised concerns among mainstream investors and companies. Tesla CEO Elon Musk and Bitcoin miners stated that they hope to solve the sustainability problem of cryptocurrencies.

Vin Diesel is a name familiar to the mass audience through the Fast and Furious series of action and speed films. The public is enjoying the 9th movie and it is expected that the series is about to close at the 10th part (it can be divided into two episodes like the way it was done at the end of Harry Potter).

According to Comicbook, Vin Diesel is particularly interested in participating in the Avatar series, which is also another popular movie franchise.

Currently, Avatar is completing the first sequel after more than a decade of causing a 3D craze, which is planned to last up to 5 parts. In a recent interview with MTV News, Vin Diesel repeatedly revealed his participation in Avatar.

"Me and him [James Cameron] have talked, but so far we have not filmed any scenes," Vin Diesel revealed to fans. "I love James Cameron. I love the Avatar series. I think it's okay to say that the two will work together soon." The open-ended statement shows that it is possible for projects that have been implemented, he could not participate in filming in time, but in the future, it is possible.

With Avatar having up to 5 parts, if Vin Diesel's film plan has enough space, we can see him appear in part 4 or 5. Or it could be another project of the talented director.

In fact, in 2019 there was a rumor that Vin Diesel would play a sequel to Avatar 2, after he posted a video on his personal Instagram revealing he was on the set with James Cameron.

Returning to James Cameron, he is putting all his heart into the project of part 2 and 3. Avatar 2 has the participation of Sam Worthington, Zoe Saldana, Giovanni Ribisi, Stephen Lang,... and many other actors from part 1.

Director James Cameron once shared that he wanted this film to be more open to the world on the planet Pandora, so that the audience could better understand the people and creatures here.

Avatar 2 is scheduled to premiere on December 16, 2022. Then there will be parts 3 (December 20, 2024), 4 (December 18, 2026), and 5 (December 22, 2028), which means that every two years the public can enjoy a new movie.

Parts 2 and 3 were filmed at the same time and have closed, now entering post-production and editing. Both of these Avatar parts use a Sony CineAlta VENICE camcorder, recording in 3D.
