The largest FAST radio telescope allowed Chinese scientists to discover more than 660 new neutron stars

Chinese researchers were able to detect a total of more than 660 previously unknown rotating neutron stars (pulsars) using the world’s largest FAST radio telescope.

“The development of the FAST project is entering its heyday, and the stable operation of the equipment of our observatory has made a great contribution to this process”, – Xinhua News Agency quotes the words of FAST chief engineer Jiang Peng. He also noted that FAST’s outstanding performance in signal interception allowed FAST to achieve better results than other similar projects.

Pulsars are one of the types of neutron stars and are the remains of large burnt-out luminaries. Their radius is only a few kilometers, but they have an extremely high density: the matter inside the pulsars is compressed so much that their mass even exceeds the mass of the Sun.

Pulsars are characterized by a strict periodicity of emitted pulses. This “pulsating” radiation can be observed due to the fact that the magnetic poles of these stars change their position relative to the Earth as they rotate. For this reason, their radiation can only be detected when it is directed directly at the Earth – just like a bright beam of light from a lighthouse becomes visible only when it turns towards the observer.

This is what FAST looks like

FAST (Five-hundred-meter Aperture Spherical Telescope) was built in 2016 in the southern Chinese province of Guizhou, and was put into operation in January 2020. It is a radio telescope with a filled aperture of the largest diameter in the world – 500 meters. Its area is equivalent to 30 football fields. The project cost was $185 million.

It is located in a mountainous area in a natural karst depression. During construction, more than 9,000 people had to be relocated from within a 5 km radius of the facility in order to minimize electromagnetic interference from television and radio stations, radars and other emitting devices.

The Moto X30 Pro charger with 125W output was previously shown on the Web, so the Moto X30 Pro will quickly charge both wired and wirelessly.

Other features of the smartphone are already known. This is a Qualcomm Snapdragon 8 Plus Gen 1 SoC, a 6.67-inch AMOLED screen with a frame rate of 144 Hz, an embedded 60-megapixel front camera and a main camera with a 200-megapixel main sensor. The official premiere of the Moto X30 Pro is expected on August 10 or 11. Moto X30 Pro was supposed to be presented earlier, but due to tensions between China and Taiwan, the premiere was postponed.

TP Link Unveils 90 TL SL31 Lite Smart Fully Automatic Door

TP-Link introduced a $90 smart door lock in China. The device, designated TL-SL31 Lite, can already be ordered in China

The creators emphasize that the lock is fully automatic – no additional actions are required with it after opening or closing the door. So, for example, when the door is closed, the lock is blocked automatically (relatively speaking, the “night latch” is automatically activated). You can unlock the device in five different ways: for example, by using a code on the digital panel, by scanning your fingerprint (response speed – 0.369 s) or from a smartphone. Naturally, the TL-SL31 Lite supports both Wi-Fi and Bluetooth.

A feature of the external design is a digital panel that rotates to the top at an angle of 15 °. The creators assure that the battery life of the lock is at the level of top solutions on the market. Well, in case of discharge, you can recharge the battery through the USB-C port.

Unlimited by power limits, the Core i9-13900K shows incredible performance, but also consumes more than a HEDT-class CPU

Unlimited by power limits the Core i9 13900K shows incredible performance

The Core i9-13900K processor, in the absence of a power limit, can compete with the monstrous Ryzen Threadripper.

Unlimited by power limits, the Core i9-13900K shows incredible performance, but also consumes more than a HEDT-class CPU

Testing showed that in Cinebech R23 in multi-threaded mode, the upcoming Intel flagship in the regular version out of the box is gaining almost 35,700 points. And this result is already very good, since, for example, the Core i9-12900K scores 27,500 points, and the 32-core Threadripper 2990X scores 30,000 points.

But if you remove the power limit, then the Core i9-13900K is already gaining more than 40,600 points! And this already correlates with the capabilities of the modern 24-core Threadripper 5965WX, and the 32-core Threadripper 5975WX is not catastrophically faster.

The price to pay for this performance will be power consumption. The CPU consumes more than 250 W under load even without any modifications, and in the absence of restrictions, the figure soars up to 345 W! This is more than the same Threadripper 5000 requires.

Recall that the Core i9-13900K will still have only eight large cores, although there will already be 16 small ones.
