What actually happens when you drink too much? The consequences are worse than previously thought

According to a new study on alcohol consumption, consumers of large amounts of alcohol may be at higher risk of developing dementia.

A team of doctors from University College London found that those who drank to the point of losing consciousness developed neurodegenerative diseases by just over twice the rate of those who did not. a. The study, which was published in the journal JAMA Network Open, was massive compared to other similar experiments. Scientists surveyed 131,415 participants, becoming probably the clearest view of the link between alcohol consumption and neurological diseases.

Interestingly enough, the increased risk did not depend nearly as much on other factors, such as how much alcohol a participant drank per week – often used to distinguish between moderate beverage consumers. And the big ones.

Those who drank a lot were 1.2 times more likely to develop dementia compared to those who drank in moderation. Both categories, however, if they have lost consciousness while drunk, are twice as likely to get insane as those who have not lost consciousness. you> a.

The study does not show that excessive alcohol consumption causes dementia in itself, as some people with neurodegenerative diseases may start drinking more or become more susceptible to loss of consciousness. In any case, it has worrying implications for those who sometimes drink a little too much.

Of course, the study is not 100% plausible, as participants may not have provided reliable information. â € œBecause many people refer to â € œconsciousnessâ € as sleep after excessive alcohol consumption, these figures are probably not accurate. These figures probably underestimate, rather than underestimate, the actual loss of alcohol-related knowledge, scientists wrote in the paper.

That being said, this new study is consistent with similar, smaller experiments that examined the same link between loss of consciousness and dementia – so it's probably worth it. take it easy with alcohol, just to be safe.

Microsoft's TikTok acquisition rejected: what's next

There have been several rumors in recent days that the sale of TikTok is unlikely. Microsoft has confirmed that they are true.

According to Microsoft officials, the acquisition of TikTok from ByteDance has failed. Apparently, the Chinese refused the financial offer of the Redmond giant, and the company founded by Bill Gates stopped making efforts on this subject.

Microsoft was defeated in the TikTok acquisition race, and the information was confirmed in a short press release released on Sunday. In these lines, it is pointed out that ByteDance, the parent company of TikTok, refused the offer to acquire the shares related to the activity in the USA, belonging to the beloved social network.

â € œWe are confident that our proposal would have been good for TikTok users, while defending national security interests. In order to implement it, we would have made important changes to ensure that the service meets the most stringent standards of security, privacy, online security and the fight against misinformation, and we have clearly stated these principles in our press release. August. We look forward to seeing how the service progresses in these important areas, ”the Microsoft statement said shortly.

It is important to note that Microsoft did not detail the specifics of the understanding it proposed to Bytedance, the exact changes it intended, or the amount of money offered. Even so, the US company's statement came online shortly after a Reuters report confirmed over the weekend that Chinese authorities were not at all pleased with the purchase and I perceive it as a form of blackmail from the United States, an offense to the Chinese government under the pretext of national security.

It remains to be seen whether ByteDance will confirm or deny a deal with Oracle, the only company left in the race for a possible acquisition. However, the deadline is very short, and if a possible agreement is not confirmed by tomorrow, September 15, it may be too late.

NVIDIA buys ARM: could be the biggest tech acquisition

NVIDIA is the largest player in the graphics chip market, but after the acquisition of ARM, it could make the law on the mobile processors side as well.

NVIDIA could become the largest chip maker on the planet after deciding to invest $ 40 billion in the acquisition of ARM. There have been speculations on this subject for several weeks, but they have just been officially confirmed. The business will position NVIDIA in a privileged position, especially on the mobile side.

As a reference, in recent years, NVIDIA has made large investments in the field of artificial intelligence, and now, it will be able to bring those proprietary technologies to mobile phones, PCs, dar È ™ i autonomous cars. At the same time, ARM will benefit from increased financial strength for research and development. To amplify the commitment to ARM technology, NVIDIA officials have promised to build a supercomputer with ARM processors at the company's headquarters in Cambridge.

â & # x20AC; & # x153; Artificial intelligence is the most powerful technological force of our times and has laid the foundations for a new wave of computing. In the years to come, trillions of computers with artificial intelligence will create a new Internet of Things that is thousands of times larger than today's human Internet. Our combination will create a company is positioned in a fabulous way in the age of AI, â € said Jensen Huang, CEO of NVIDIA.

NVIDIA officials have noted that most of ARM's current business model will remain untouched under the new owner. This means that ARM technology licensing agreements with partners will remain in effect. However, we may see more capable mobile processors in the near future, after they come to include NVIDIA technologies. It remains to be seen how this acquisition will affect competition between AMD and NVIDIA

Although such a large acquisition needs a lot of approvals, it is important that the leaders of the two companies have reached an agreement. But there is still a laborious process that will take place over the next 18 months. Meanwhile, they will try to convince the EU, China, US and UK authorities that they will not be able to create a monopoly in the industry.

The first day of school has also arrived on Google: what appeared on the front page on September 14th

The first day of school in 2020 starts strangely: some students will take online classes, others offline. Google marks the moment with a doodle on the front page.

According to official figures, more than three million students will start school on September 14th. But about 100,000 of them do home schooling online. However, not all of them have tablets or laptops or a stable internet connection. At the same time, for the first day of school there are the old problems: lack of textbooks, lack of toilets, lack of ISU operating permits.

Before the first day of school, almost 150 teachers retired as a matter of urgency. Another nearly 300 are already infected with the new coronavirus, are quarantined and about 100 are hospitalized.

As you can see, Google has put together, in this doodle, several elements reminiscent of the school: notebooks, geometry kit, a calendar, a computer, a roulette wheel, but it's also a laptop. And, unlike other years, a medical mask. Basically, Google has adapted to what the first day of school means during this period.

Regarding the situation for the education system, in Bucharest, several schools that were initially in the yellow scenario asked to move to the red scenario because rehabilitation works that are not ready. In total, there are 29 schools that will remain closed. The remaining 607 will operate in the yellow scenario, with hybrid learning.

Moreover, in 12,423 schools, students can physically attend classes. In 4,915, the hybrid learning scenario will be adopted. At the national level, in 262 schools students will learn exclusively online, right from the first day of school.

As a structure, this school year has the first semester of 17 weeks (September 14 – January 29, 2021) and the second semester of 17 weeks of courses (February 8 – June 18, 2021). the final classes in high school education, the school year has 32 weeks of courses and ends on June 4, 2021.

Streaming video games reaches the iPhone and iPad: what rules Apple has imposed

Apple has succumbed to market pressures and decided to allow streaming of video games on iOS. However, the Cupertino giant's new regulations may be too complicated for Google, NVIDIA, Microsoft and others.

Apple's fix on not allowing streaming games on iDevices starts with an explanation as simple as possible. The creators of iPhones and iPads want to make sure that every game or application that can be experienced on the gadgets in the portfolio complies with the Apple AppStore's terms and conditions of use.

Based on this reality, the compromise solution that Apple thought of is simple. Although you will be streaming games, every title that will be available in this format must be “downloaded” from the AppStore. I put it in quotes, because streaming itself involves accessing a cloud gaming experience. I don't know exactly what you could download from the AppStore so that the whole concept is still streaming.

“Games offered through a subscription game streaming service must be downloaded directly from the AppStore, must be created to avoid double payments to the subscription provider, and should not disadvantage non-subscribers.” shows in the new list of terms and conditions imposed by Apple.

â € œGame streaming services can provide a catalog application in the AppStore to allow users to subscribe to the service and find games in the AppStore, provided that those applications comply with all of Apple's terms and conditions, including the ability for users to pay for subscriptions through in-app purchases and use the Sign in with Apple authentication system. All games included in the catalog application must include a link to an individual product page in the AppStore.â € It is also mentioned in the same document.

In any case, Apple accepted the idea only under these conditions. If giants with such services are open to adapting, you'll be able to have services like Google Stage, Microsoft xCloud, and NVIDIA GeForce Now on your iPhone and iPad.

Screenshots on Mac: How to customize the Screenshot experience

I spend a lot of time taking screenshots for tutorials and various news, and because I'm a Mac user, I've been looking for some solutions to customize the capture experience.

If you're using an Apple system, you have a number of options for taking screenshots. From the Preview application, which opens photos or PDFs by default on the Mac, go to File and choose Take Screenshoot. Immediately, you have three options for capturing screenshots, one area (Selection), one full window (Windows), and full screen.

On the Mac, in addition to a dedicated application called Screenshot, which you can find by clicking on the magnifying glass at the top right of the screen, you have some key combinations with similar results. Press Shift Command 3 to take a full screen capture. To capture a section of the screen that you define manually using the cursor, press Shift Command 4.

By default, all your screenshots go to Downloads, the directory you find in Finder, and where you download and download files from the Internet. To change that location, you need to open Terminal by clicking the magnifying glass on the top right or the Launchpad in the Other section.

Create the desired screenshot folder in the Finder and leave the window open. Enter the terminal and write “com.apple.screencapture location” without quotes. Put a space at the end and drag the previously created directory into the terminal window to automatically complete the path to it. Press Enter to confirm.

Another detail that helped me was to change the default screenshot extension. These are PNG type, and I need JPG. You can also choose TIFF, GIF or PDF, in addition to PNG. To change the capture format, open Terminal and type, without quotation marks, “com.apple.screencapture type”, followed by the space and extension for the desired format. I used “com.apple.screencapture type JPG”. From that moment, all screenshots are in JPG, until the next time I change the extension.

European companies competing with Tesla and have a chance to win

European technology companies such as Rimac, Skeleton Technologies and Einride are competing with Tesla and are close to winning. Europe produces faster cars and better batteries than Tesla.

While Europe does not have a single Tesla equivalent, but several companies that are part of what Tesla does, in many cases Europe is doing better.

Lacking the media influence of Musk's empire, they are less well known, but there are companies like Rimac that make electric roadsters faster, companies like Skeleton Technologies that produce more powerful ultracapacitors and Einride that produce electric trucks with automatic driving, informs sifted.eu.

The Tesla Roadster is considered the fastest car in the world. According to the company, it can reach from 0 to 100 km / h in just 1.9 seconds and has a top speed of over 400 km / h.

Rimac from Croatia could break the Tesla record. The C-Two electric vehicle can accelerate from 0 to 100 km / h in 1.85 seconds and reach a top speed of 570 km / h.

For now, however, the Rimac C-Two is not in production. Potential customers will have to wait until 2021 to receive delivery. There may be a very limited number of vehicles, which means you are more likely to be able to deliver. it gets a Roadster rather than a C-Two.

Piech is based in Switzerland, but has deep roots in Germany and is linked to Volkswagen. The company was founded by Toni Pich, the son of former Volkswagen President Ferdinand Pich. It began to be based on the German history of top engineering, combined with electric motors and became the “luxury electric mobility brand”.

The company's all-electric model, Mark Zero, scheduled for sale in 2022, can reach 100 km / h in 3.2 seconds and charge 80% of its battery in 4 minutes. And 40 seconds and boasts a range of 500 km on a single charge.

More than 200 Bosch employees have been involved in the construction of important parts of Nikola trucks, including the electric axle motor, vehicle control unit, battery and hydrogen fuel cell.

The biggest photo ever taken: the camera has 3.2 billion pixels

Scientists plan to use this huge camera to capture comprehensive images of the southern sky as part of a study called the Legacy Survey of Space and Time (LSST).

The study will help scientists see our universe better than ever and solve some of the great mysteries of astronomy, such as how galaxies evolve and how they evolve. in which theories about dark matter and energy collide with reality.

The camera is set to make its final journey from Northern California to Chile's Rubin Observatory, but the Stanford team took some test photos to prove its tremendous power, according to inverse.com.

An image of a vegetable may not sound like technological evolution, but Vincent Riot, the defense room project manager at the Livermore National Laboratory in the Department of Defense, said the first photos are an incredibly important step. to demonstrate how the camera will work when shooting space.

“This is a huge milestone for us,” Riot said. “The focal plane will produce the images for LSST, so it will be the sensitive eye of the Ruby Observatory.”

The basic design of the camera is no different from that of ordinary smartphones: light emitted by an object or reflected by an object is captured by light-sensitive components and converted to electrical signals. These signals can be translated into accurate pixel information to compose a photo.

What stands out in the design of this camera is that it has 189 individual light sensors, which bring all the 16 megapixel information.

In comparison, a standard mobile phone only brings up to 16 megapixels in total, the power at 1/189 level of this device.

The sensors are grouped into nine to form what the team calls a “science series.” Each sensor is 2 meters high and weighs 20 kilograms and costs $ 3 million.

The device that will help you sleep better uses a revolutionary technique

A team of MIT researchers has developed a device that can monitor people's sleep positions without the need to use cameras or stick sensors on their bodies.

It is a wall-mounted monitor, called the BodyCompass, and works by analyzing radio signals as it monitors objects in a room.

As the researchers explained, a device that can monitor sleep stations has many potential uses. It could be used to monitor the progression of Parkinson's disease, for example, because people with this condition lose their ability to go back to bed during sleep.

To differentiate between radio signals that receive from a body and signals that receive from random objects in a room, the system focuses on signals that receive from the chest and abdomen. to a person.

In other words, the parts of the body that move while the person is breathing. It then sends those signals to the cloud so that the BodyCompass system can analyze the user's position.

The team trained the neural network of creation and tested its accuracy by collecting 200 hours of sleep data from 26 subjects who had to wear sensors on their chests and breasts. belly at first. They said that after training the data device for a week, it predicted the correct position of the subject's body 94% of the time.

In the future, BodyCompass could be paired with other devices to stimulate a change of position, such as smart mattresses. When this happens, the device may warn people with epilepsy if they have a potentially fatal sleeping position, reduce sleep apnea events and notify caregivers to move patients. ›Ii real estate. It could also help everyone sleep better, because we certainly all need it.

The phenomenon that has not happened for 50 million years: global temperatures, growing alarmingly

Global temperatures will reach unprecedented levels in 50 million years by the end of the century if greenhouse gas emissions are not significantly reduced, a study warned.

German and American experts have analyzed tiny fossils of nuclei drilled from the bottom of the sea to reconstruct the Earth's climate history in the time of the dinosaurs. During this 66 million year period, the planet has seen four distinct climatic states – which scientists have called “hothouse”, “warmhouse”, “coolhouse” and “home.” œicehouseâ €. Each of these states is characterized by special concentrations of greenhouse gases and the extent of ice that is stored at the Earth's poles.

For most of the last three million years, the Earth has been in a state of “icehouse” – one characterized by alternating glacial and interglacial periods. However, greenhouse gas emissions and other human activities are now pushing the climate into “warmhouse” and “hothouse” states, experts have warned.

Heat conditions were last seen in the Eocene, which ended about 34 million years ago and in which there were no polar caps. During this time, global average temperatures were 9-14 degrees Celsius higher than they are today.

“The projections of the intergovernmental group on climate change for the year 2300 in the scenario of 'normal emissions' will bring the potential of global temperature to a level that the planet has not seen in 50 million years,” he said. the author of the work James Zachos.

Also in their study, Professor Zachos and his colleagues created a “climate reference curve” called CENOGRID, which shows the global temperature changes from the past to the present and includes various predictions for the future based on emission levels.

“Now we know exactly when it was warmer or colder and we have a better understanding of the underlying dynamics and the processes that drive them,” said the author and the geologist. sailor Thomas Westerhold. â € œThe time from 66 to 34 million years ago – when the planet was much warmer than it is today – is of particular interest, as it represents a parallel in the past with what it could lead to future anthropogenic change, ”he added.

“We have long known that glacial-interglacial cycles are marked by changes in Earth's orbit,” said Professor Zachos, who conducts research at the University of California, Santa Cruz. These cycles, he added, “change the amount of solar energy that reaches the Earth's surface, and astronomers have calculated these orbital variations back in time.”

Prof. Zachos' previous research has established that a period of rapid global warming about 50 million years ago, which led to climate change in a greenhouse state, was caused by a massive release of carbon in the atmosphere. Similarly, at the end of the Eocene, with the fall of atmospheric carbon dioxide, ice sheets began to form in Antarctica, and the climate shifted to a state of cooling.
