After the first critical test of iPhone 12 and iPhone 12 Pro appeared yesterday, a new report from Tom's Guide revealed the rate of decrease in battery capacity when using 5G. The report outlines a test process in which the iPhone continuously browses the web at a screen brightness of 150 nits and opens a new website every 30 seconds until the battery runs out. The test was performed under iPhone 12 and 12 Pro, which were logged into 4G and 5G networks, respectively. When using 5G, it took 8 hours and 25 minutes for the iPhone 12 to run out of battery, while the iPhone 12 Pro took 9 hours and 6 minutes. When using 4G, iPhone 12 and 12 Pro performed better, with battery life of 10 hours, 23 minutes and 11 hours and 24 minutes, respectively. This means that in this artificial benchmark, when using 5G, the battery life of the iPhone 12 and iPhone 12 Pro is about 20% faster. Tom's Guide reported that under the same test, this is almost the same as the battery performance of a 5G An...

Remember the "one-click stripping AI" DeepNude? In June last year, this in-depth software was released for only a few hours, and it went down quickly due to excessive access requests. The reason was that it could take off women’s clothes with one click and create a large number of pornographic images. Recently, according to investigations, this pornographic software appeared again in the instant messaging application-Telegram. Up to now, the software has publicly released about 104,852 pornographic pictures on the TeleGram platform. This data does not include the pictures shared privately. More importantly, 70% of these pictures are all from real women on social networks, even minors. In other words, the selfies that are shared daily on social media such as Facebook and Weibo are likely to be used to generate "fruit photos." DeepNude is eyeing "someone you may know" The investigation comes from Sensity, a cyber security company based in Amsterdam, which fo...

  The Mate 40 series is getting closer, and I will meet with you tomorrow night, and the exposure has reached the most exciting stage.  The ring-shaped rear five-camera module is exactly the same as the previous exposure, with a flash on the top.   As it is an engineering machine, there is no Leica logo printed on the middle part of the camera. At the same time, it can be seen that the design and curve of the fuselage are basically in line with the previously exposed renderings, but the renderings of Huawei's new phones have always been poor, and the real phones will be even more amazing. At present, there are four models in the Mate 40 series. The Mate 40 standard version has three rear cameras, the Mate 40 Pro has four rear cameras, and the Mate 40 Pro+ has five rear cameras, which are similar to the Mate 30 series. Ring shape. The top Mate 40 RS Porsche is also five-shot, but it is changed into a gossip picture or a palace lantern octagonal window shape, and an in...

The hot, dense, and expanding cloud of debris that was stripped from the neutron star before the neutron star collided. The collision between two dense objects such as two neutron stars or a neutron star and a black hole is called a thousand novae. NASA's Thousand Nova illustrations show clouds in visible and infrared light. In the neutron-rich debris after the collision, a large number of some of the heaviest elements on earth are produced. The most surprising thing is that there are hundreds of earth-mass gold and platinum in that fragment cloud. Most people are familiar with the term supernova, which refers to a huge explosion produced by a star much larger than the sun. A supernova explosion is the largest explosion known to man. Although a thousand novae are not as bright as a supernova, the brightness of a thousand novae can be 1000 times higher than that of the nova produced when a white dwarf explodes. Thousand novae are the main source of gold in the universe, and neutron ...

Apple announced the iPhone 12 family that fully supports 5G communications at the second fall conference held today. First, introduce a smaller iPhone 12 5G model, which is thinner (11%), smaller (15%), lighter (16%), and narrower than the iPhone 11. Equipped with the previous iPhone 11 and iPhone XR The same 6.1-inch display. This "main" iPhone is transitioning from an LCD screen to a Super Retina XDR OLED screen, with a pixel density of 460 PPI (twice the iPhone 11). Support 1200 nits brightness, Dolby visual effects, HLG, HDR10 and other display features. As rumored, the side bezel of this phone is flat, and the overall appearance is closer to the iPad Pro and iPad Air (plus the iPhone 4 years ago). The new material Ceramic shield from Corning will make the new iPhone have harder front and back glass than any smartphone. The fuselage glass is also stronger and tougher than before, and its anti-fall performance is four times that of the past. iPhone 12 will have four colors...

According to foreign media BGR, loss of smell and taste are the most common symptoms of the new coronavirus--and one of the clearest indicators of the possible presence of the COVID-19 virus. A new study in India took a closer look at this particular indicator of the new coronavirus to see if the loss of the ability to recognize specific odors may be a more definite symptom of new coronary pneumonia. What the scientists discovered was that study participants who were unable to identify two of the five odors in the study were most likely to test positive for COVID-19. According to a recent analysis by the New York Times, almost 90% of patients with COVID-19 report loss of smell and taste, and a study by Vanderbilt University Medical Center even found that approximately 25% of people diagnosed with COVID-19 report Said that this is their only symptom. And now, researchers have learned more key information about smell and the presence of COVID-19 especially about when people report losing...

According to foreign media New Atlas, as antibiotic-resistant bacteria will become a huge health problem in the coming decades, the world urgently needs new drugs and treatments. Now, researchers at the University of Pennsylvania have designed new antibacterial molecules from wasp venom, which has shown promise in tests on mice. Antibiotics are one of the most important scientific breakthroughs of the 20th century, preventing many people from dying from infections. But unfortunately, decades of overuse have caused bacteria to increasingly develop resistance to drugs. It is predicted that without intervention, by 2050, these "super bacteria" may cause up to 10 million deaths each year. In order to prevent this nightmare scenario from happening, scientists are studying a whole set of new candidate antibiotics and are also looking for other non-drug methods to destroy them, including lights, materials, magnetic nanoparticles that shred them, and even molecules. A particularly pr...

With the continuous advancement of technology, smart phones are becoming more and more powerful, but they also bring some other problems, such as heat. But for mobile phone designers and engineers, it is necessary to take into account the space problem while solving the heating problem. A new research from King Abdullah University of Science and Technology has developed a brand-new heat-dissipating graphite film, which not only can perfectly solve the problem of mobile phone heating, but also takes up very limited space. It is reported that graphite film has excellent thermal conductivity, which provides the possibility for the thinner development of electronic products and is an ideal material for heat dissipation of electronic equipment. However, its production cost is relatively high, it needs to be processed at a high temperature of up to 3200°C, and the thickness of the finished product is also several microns. According to researchers at King Abdullah University of Science and Te...

According to foreign media CNET reports, astronomers have discovered that two neutron stars collide with each other about 130 million light-years away from the earth. On August 17, 2017, the collision between some of the densest celestial bodies in the universe produced gravitational waves and X-rays. Dozens of telescopes on Earth have captured this rare merger at different wavelengths of the electromagnetic spectrum. First, there is a burst of high-energy gamma rays, followed by a burst of light and ultraviolet, radio and infrared signals. About nine days after the collision, NASA’s Chandra Observatory received X-ray signals. According to astronomers' understanding of neutron stars, it should have disappeared by now. But in a new study published on Monday in the Journal of the Royal Astronomical Society , researchers studied the neutron star collision called GW170817 and found that after 1,000 days, X-ray signals can still be detected. "We really don't know what to expect...

Since the launch of the new iPad Air tablet with A14 chip last month, Apple executives have introduced some of the development details behind it in a series of interviews. For example, before the iPhone 12 conference, Apple’s vice president of platform architecture Tim Millet, and Mac and iPad product marketing senior director Tom Boger, during a new round of interviews with foreign media, talked about the energy efficiency of the custom chip.  (Picture via MacRumors ) It is reported that Apple may announce four new iPhone 12 family products at the press conference at 1:00 am Beijing time , featuring the same A14 chip as the iPad Air 4. It is manufactured based on the latest 5nm process, which can package more transistors in the same area and run at lower power. In addition, the new technology allows the A14 to accommodate more components besides the CPU/GPU, such as doubling the size of the neural engine (to 16 cores), and can perform 11 trillion operations per second, which is al...

According to foreign media reports, our sun is a relatively predictable star. We know that it has cycles, we roughly know its age, and we think we know how long it will last in its current state and eventually "tan out" and destroy most of the solar system. But there are many different kinds of stars in the universe, and some stars are much stronger than the sun. A star named Apep is not only very rare, but the information currently available shows that it will not exist for long. This is a Wolf-Rayet star. To earn this title, the star must be both bright and hot and seem to be constantly at risk of collapse and explosion due to the amount of fuel exhausted. Obviously, the specific conditions of stars meeting these criteria are very rare, and only one in 100 million stars will receive such a label. Apep is such a star, but it is actually much rarer than it appears on the surface. This is because Apep is not a lone star but a double star, and they dance gracefully around each ...

After continuing with the Galaxy A51 5G, Samsung launched a new entry-level Galaxy A42 5G that is more affordable. The listing price of the former is 429 pounds (US $500), but the latter is only 349 pounds (about 3070 RMB). Although the price has been reduced by 80 pounds, the Galaxy A42 still uses the Snapdragon 750G mid-range chipset newly released by Qualcomm last month. (From: Samsung official website) Compared with the Snapdragon 730G used on Google Pixel 4a and other devices, the performance of the 750G chipset is slightly improved, but it is still not as good as the Snapdragon 765G SoC carried by competing products such as Pixel 4a 5G / OnePlus Nord. In addition, Samsung equipped the new Galaxy A42 5G with a 6.6-inch drop-shaped OLED screen, a front 20MP single camera, and a rear 48MP main camera + 8MP ultra wide-angle + 5MP macro + 5MP depth sensor. The machine can choose 4GB / 8GB RAM + 128GB ROM storage combination (support microSD expansion), support fingerprint recognition ...

According to a recent report by the American Fun Science website, the latest research by American and German scientists indicates that there may be 24 planets outside the solar system that are more habitable than the Earth. These planets are "older", warmer and wetter, and a bit bigger than the Earth. Some of these planets may be excellent places to find alien life. The research was led by Professor Dirk Schulze-Marcucci of Washington State University, who worked with astronomers at the Max Planck Institute for Solar System Research and Villanova University to make the latest discoveries. Among the extrasolar planets discovered by astronomers so far, most are not conducive to the survival of life, but in the habitable zone of stars, there are many planets that may be suitable for life to thrive. The habitable zone means that the distance between the planet and the star is just right, so that its surface temperature is not lukewarm for life as we know it. The goal of Marcucci’...

There is a popular saying in the industry that "any application that can be written in JavaScript will eventually be written in JavaScript", and this is Atwood's Law. JavaScript is almost everywhere, and its popularity continues to grow. Recently, based on the Python beginner series, Microsoft has released a free teaching video for a total of 51 class hours. Throughout the course, Microsoft helps users use Visual Studio Code to set up the development environment, install Node.js as JavaScript Runtime, and then directly create the "Hello World" application. The grammar of JavaScript is provided in the course, and more advanced topics are gradually studied, including objects and programming with asynchronous functions. Finally, explore the JavaScript ecosystem and the large number of packages and libraries available on NPM in the course. At the beginning of this course, Microsoft will also introduce (many) places where JavaScript can be run, including browsers and...

According to foreign media New Atlas, dopamine and serotonin are brain chemicals related to a series of neurological diseases such as Parkinson's disease and depression, so understanding how they work may be the key to developing more effective treatments for these diseases. A new tool provides an unprecedented opportunity to observe the effects of these neurotransmitters, enabling scientists to monitor their real-time activity for the first time. For a long time, both dopamine and serotonin are related to the brain's ability to process rewards, but recently scientists have turned their attention to how they play a broader role in the entire human body. This includes how serotonin in the intestine regulates blood sugar or how ketamine solves the problem of low levels, and how deep brain stimulation (DBS) promotes dopamine production in Parkinson's disease patients. The last example is a particularly promising example, because Parkinson’s disease is characterized by the depl...

According to statistics from the World Health Organization (WHO), in the three days from October 8th to October 10th, the number of newly diagnosed COVID-19 patients worldwide increased by 1 million. With the arrival of autumn and winter in the northern hemisphere, the control of the COVID-19 epidemic still faces severe challenges. Fast and accurate nucleic acid testing can help medical workers find patients infected with the new coronavirus earlier, so that they can be treated/isolated and contact tracing. Most of the current nucleic acid tests still require samples to be sent to specialized laboratories for processing, and it often takes a day or even longer to obtain results, which may delay the time for patient treatment and isolation. Therefore, researchers are unanimously striving to develop faster and easier nucleic acid detection. Using CRISPR technology to speed up detection is one of the directions. The WuXi AppTec content team also reported previously on the efforts of the t...
