An unusually long radio signal from space has been detected. Maybe it’s the sound of a neutron star

Astronomers from the Massachusetts Institute of Technology and scientific institutions around the world have detected a strange radio signal from a distant galaxy. According to the classification, it belongs to fast radio bursts (Fast Radio Bursts, FRB) – radio waves of unknown astrophysical origin, which usually last no more than a few milliseconds.

However, this signal lasts up to three seconds – 1000 times longer than the average FRB. Astronomers also found others inside these bursts, repeating every 0.2 seconds with a clear periodicity, similar to a heartbeat. The new signal, named FRB 20191221A, is the longest FRB with the clearest periodic pattern detected to date.

The source of the signal is located in a galaxy several billion light-years away from Earth. What this source is is not clear. However, there are not many objects in the Universe that emit strictly periodic signals, therefore, according to scientists, FRB 20191221A may come from a radio pulsar or magnetar. Both of these apply to neutron stars.

The specs for almost every Intel desktop processor of the Raptor Lake generation have surfaced online.

Almost all new Intel Core processors will have 14 or more cores.  Specs for most Raptor Lake CPUs revealed

According to this document, we are waiting for 14 CPUs with the number of cores from four to 24, while there will be only one quad-core – Core i3-13100. The next model (Core i5-13400) will have 10 cores, and it will also be the only one, because the Core i5-13500 and a number of older CPUs will already offer 14 cores.

Only the Core i9s will get the new die type, as only they will have a full configuration with eight large and 16 small cores. By the way, the Core i9-13900KS is not in the table, so it really may not be, especially if we recall the recent data on the 350-watt power limit for older Cores.

4G and 5G are now only their own without foreign

The Government of India has decided to limit the access of foreign companies to the market of cellular networks. Now the state-owned companies BSNL and MTNL should implement projects for the modernization and construction of 4G and 5G networks only with Indian companies.

4G and 5G are now only their own, without foreign companies.  Indian government directs BSNL and MTNL to work only with Indian firms

For these purposes, BSNL and MTNL received about $20 billion. The Indian government wants all of the industry’s core technologies to be developed domestically without much dependence on foreign players. India also wants all intellectual property to remain inside.

However, it is not clear how this will affect the development of 5G networks in India, because it will take Indian companies a lot of time to develop the appropriate equipment.

Apple has reported a possible vulnerability in the operating systems

A vulnerability has been discovered in the operating systems of iPhones and iPads that could give hackers full administrative access to devices. It is in the core of the system and in the engine for displaying WebKit web pages. As noted, the problem has been fixed in the latest firmware versions.

Apple has reported a possible vulnerability in the operating systems of the iPhone and iPad

The media talked about this, and also said that some “anonymous researchers” helped discover the company’s vulnerability, but Apple did not disclose details.

As follows from the report, attackers could run applications with administrator privileges and act on behalf of the owner of the device. The issue affected iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation). This affected the iOS 15.6.1 and iPadOS 15.6.1 operating systems.

The company’s technical support has already stated that the problem has been fixed, and independent experts have stated that they recommend updating the OS to the latest current version.

The full iOS 16 update will be released in September, and watchOS 9 for smartwatches is also expected. But the new version of iPadOS will appear later, like macOS Ventura.
