Google introduced two new smartphones with 5G support

Google introduced the flagship smartphone Pixel 5 and more budget model Pixel 4a 5g. Other innovations include a “smart” speaker and a new operating system for TVs.

Google held a presentation of Live Night In, which showed the main novelties. The company presented two new smartphones — Pixel 5 and Pixel 4a 5g.

The body of the smartphone Pixel 5 is made of recycled aluminum. It is equipped with a processor Snapdragon 765G and a six-inch OLED-screen with glass Gorilla Glass 6. The smartphone has 8 GB of RAM and 128 GB of built-in memory, It runs on a battery of 4080 mAh. Preorders for Pixel 5 are already accepted, sales will start on October 15. Google Pixel 5 is available in the U.S. at $699.

More budget smartphone Pixel 4a 5g will cost in the U.S. $499. The smartphone received a 6.2-inch OLED display (the original Pixel 4a had a 5.8-inch screen). The smartphone will have the same processor as the more expensive version — 8-core Qualcomm Snapdragon 765G, the same built-in memory (128 GB), but it will have less RAM (6 GB) and battery capacity (3885 m-H).

Also in the presentation, Google showed a new “smart” speaker Nest Audio worth $99 and a new version of Chromecast media player.

A digital novelty of the presentation was the new operating system for Google TVs. It will replace the Android TV operating system, as well as mobile applications Google Play Movies, and TV.

Isn’t Paris pressure too high when developing a 5G network?

The tender for frequencies for 5G networks has been launched in France since Tuesday. In this regard, discussions about the opportunities and risks of this newest technology have once again heated up. Greens demanded to suspend 5G network expansion, and President Macron responded with a severe failure. Mass media believe that horses should not be driven away.

Legitimate questions require answers

The debate about 5G technology is being conducted using the wrong rhetoric, — says Le Monde:

“Those who are somehow against this innovation adjoin those who consider discussions about it a waste of time because the benefits of the technology are obvious to everyone. But in both cases, the finale is unproductive: ‘Pass by, there’s nothing to see!’ But it’s quite the opposite: it’s absolutely legitimate to question the impact of 5G on the economy, environment, and technical safety… Transport issues, development of the city of the future, production methods — all these areas can undergo major changes with the help of new technology. But what will it mean for the environment? What benefits will it bring to people who are analyzing their dependence on new technologies? By the way, what about personal data protection guarantees? All these questions need to be answered.

Everything is going too fast!

According to L’Obs, progress is alarming:

“It’s rare that any innovation has received such a strong response. Before, technical progress was synonymous with growth and growth was synonymous with well-being. Both in the camp of the Left and in the camp of the Right, this dogma was most widespread, but with the onset of global warming, such truths are scattered like a house of cards. The world has realized that our economic model leads us straight into a dead-end — replacing reflection with reflexes and putting us to sleep with a ‘technological bluff’, as philosopher Jacques Elleulptly put it. …. If 5G has caused this reaction, it is because it is the embodiment of evil that paralyzes us in the face of climate change. It is a new acceleration factor that encourages us to think carefully about every move.

COVID tracking apps in Europe fail

Contact tracing apps for people infected with the new coronavirus in Europe have proven ineffective.

According to Harald Lindlar, a spokesman for one of the Deutsche Telekom developers, the Corona-Warn-App has been downloaded 18.6 million times on devices. However, only 5 thousand people shared a positive test for COVID-19, and about 70 thousand Germans got sick since the launch of the application.

The officials themselves note that it is too early to talk about the effectiveness of such programs since citizens do not trust such systems.

The authorities faced similar problems in Switzerland, Finland, and the UK, where mobile applications were also thrown in the fight against the new coronavirus.

Recall that an outbreak of an epidemic of a new infection occurred in Wuhan at the end of December 2019. The causative agent of the disease was a new type of coronavirus, the disease was named COVID-19, and on March 11, WHO announced a worldwide pandemic.
At the moment, more than 33 million people have been infected with the new coronavirus around the world.

On Mars, lakes with water were found

We are not talking about living organisms on the Red Planet yet.

Three underground lakes with water were detected near the South Pole of Mars using the radar of the automatic interplanetary station of the European Space Agency “Mars Express”.

This is reported by the BBC.

At the same time, we are not talking about the presence of living organisms on the Red planet — the scientists believe that the water in the Martian lakes is so salty that even the most persistent microbes will not survive.

It is known that on the surface of Mars water in its liquid form can not be due to too thin atmosphere and low temperature. The found lakes are located at a depth of about one and a half kilometers under the polar cap, which consists of ice and sand.

It is noted that previously one such lake has been found in 2018.

Scientists’ version of the high salinity of water in the found lakes is based on the fact that underground Mars temperature is significantly below freezing point. At this temperature, the water in the liquid state can remain only with a high content of salts.

The experiments showed that water saturated with salts of magnesium and calcium perchlorate turns into ice at -123 degrees.

The discovery was made with the help of Marsis radar onboard the orbital station “Mars Express”, which has been circulating around the Red Planet since December 2003.

Scientists have developed a hearing aid for one dollar

The device devoid of sophistication will help millions of elderly people with hearing problems who do not have the means to purchase expensive devices, the developers believe.

In the U.S., a team of engineers from the Georgia Institute of Technology introduced a hearing aid that can be assembled by yourself, spending only one dollar on components for the device. This is what Sci-Tech Daily reports.

“The main problem with existing hearing aids is their price. Because the average cost of a gadget is about $4,700. Their budget analogs are around half a thousand”, — the developers compare.

To reduce the cost of hearing aids, scientists abandoned expensive digital signal processors and instead installed electronic filters to adjust the frequency parameters.

“This part is hidden in a case printed on a 3D printer and is powered by a flat or finger battery,” — explain the scientists.

Lead author Sohum Singh himself suffers from hearing loss.

“I was born with a hearing loss and didn’t use hearing aids until after high school. This project provided me with an opportunity to find out what I can do to help other people who are in the same situation as me but don’t have the resources to purchase hearing aids,” Singh said, answering the question of why he decided to develop a budget gadget for the hearing impaired.

At the same time, the device is not without drawbacks: so far, its size is larger than that of its analogs, and the expected service life is one and a half years. You need to change the batteries in the device once in three weeks.

However, as the authors of the gadget assure, they continue to work on its size.  In the near future they are going to release a compact version of the device, and then move on to clinical trials.

It is known that around the world 230 million people aged 65 years and older are experiencing hearing loss. It usually becomes difficult for them to distinguish between high sounds — the squealing of electronic devices, for example — and certain consonants. It is difficult to understand the speech of the interlocutor, the background noises become incomprehensible and distracting. Such processes can, in the opinion of doctors, accelerate the decline of cognitive abilities.
