Scientists have proposed looking for traces of dark matter in the atmosphere using radar. A preprint of an article about this is published in the arXiv repository.

Scientists suggest using Earth's atmosphere as a dark matter detector

In the 20th century, when analyzing the rotation of the arms of spiral galaxies, serious anomalies were discovered. The stars in them do not rotate around the center as they should, as if they were affected by a large hidden mass. In this regard, astronomers have introduced the concept of dark matter – a variable that, when added to the equations of motion, makes the model look like real life. It is believed that this dark matter does not interact with electromagnetic radiation, including light, and therefore it cannot be seen, it can only be calculated from the gravitational influence.

Ohio State University experts have suggested that relatively large (and rare) particles of this matter can be detected by atmospheric traces. These traces can be fixed by a radar designed to search for traces of meteors. The proposed method for detecting dark matter particles is based on the assumption that the Earth’s atmosphere is a giant analogue of a cloud chamber, the simplest detector of charged particle tracks, inside which ions that cause vapor condensation leave behind traces of water droplets.

Such an idea was expressed based on the results of simulations, which showed that particles of macroscopic dark matter with a large mass and a high effective cross section (that is, a high probability of interaction with another particle) upon entering the Earth’s atmosphere also produce an ion cloud due to interaction with atmospheric particles.

“This screen should be on all phones.” Reviews of Realme 10 Pro+ with ultra-thin bezel and 2160Hz PWM appear

This screen should be on all phones Reviews of Realme

One of the first reviews of the Realme 10 Pro + smartphone has appeared on the Web, and the device really deserves attention.

This screen should be on all phones Reviews of Realme

The journalists of the Gizmochina resource most of all praise the new screen, arguing that this should be in every smartphone. Recall, the new Realme is equipped with a curved OLED display with a very narrow frame. But it is also one of the first devices on the market that supports PWM at a frequency of 2160 Hz. Thanks to this, the use of a smartphone should not cause discomfort for people who are sensitive to flicker.

Our colleagues also note a low weight of 180 g, but Realme achieved it quite simply: both the case frame and the back cover are made of plastic.

The performance of the smartphone is very high, as it has a new Dimensity 1080 SoC, which is slightly faster than the Dimensity 920.

As for the rest, the novelty has a decent 108-megapixel camera, a lot of memory, excellent autonomy and good software (Android 13 with Realme UI 4 shell).

No overheating, no throttling, no screen brightness reduction. The head of Xiaomi promises 60 fps in Genshin Impact for Xiaomi 13

No overheating no throttling no screen brightness reduction The head

The head of Xiaomi, Lei Jun, continues to praise the upcoming flagships of the Xiaomi 13 line. And gamers should like his new message.

More precisely, gamers who love the mobile version of Genshin Impact, one of the most resource-intensive games on smartphones.

No overheating, no throttling, no screen brightness reduction.  The head of Xiaomi promises 60 fps in Genshin Impact for Xiaomi 13

According to the head of the company, future flagships will be able to cope with this game without problems at maximum graphics quality settings and at 60 fps. And while supposedly there will be no overheating or throttling.

Of course, high performance is primarily due to the new Snapdragon 8 Gen 2 SoC, and not directly to Xiaomi flagships. But the absence of overheating and throttling suggests that the company has worked on the cooling system. Allegedly, even under load in the game, the temperature will not rise above 43 degrees. And even if you charge your smartphone at the same time.

Moreover, even the screen brightness will not decrease after a while, which, unfortunately, has become the norm for most flagship devices in recent years.

It remains to wait for the release of new products and look at the test results.

Chinese smartphone manufacturers continue to develop their own semiconductor solutions. Oppo has revealed that it will soon introduce the MariSilicon X Gen 2 image processor.

The

As the name implies, this is the second generation, the first one debuted in the Find X5 Pro. While there are no details on what will be the difference between the new chip and the old one, Oppo is talking about some breakthrough developments aimed at numerous innovations.

The new chip will be unveiled on December 14 at the Oppo Inno Day event. Then the company can tell in which smartphone MariSilicon X Gen 2 will appear for the first time. But, most likely, it will be Find X6 Pro, the image of which we saw today.

At one time, the cameras of both Find X3 Pro and Find X5 Pro were highly appreciated, including by DxOMark experts. Even now, these devices are ranked 26th and 21st, respectively, in the overall ranking, bypassing the iPhone 12 Pro.
