A clear example of how incredible the James Webb Space Telescope turned out

The James Webb Space Telescope has recently completed the alignment process and is almost ready for full-fledged work. Scientists do not get tired of saying that the observatory exceeds all their expectations, but the first normal (not test) images will have to wait another month or two. However, it is already possible to understand why the new telescope is better than the old ones.

This is a collage created by astronomer Andras Gaspar. The image shows the same piece of space – part of the Large Magellanic Cloud. The very first image was taken by the Wide-Field Infrared Survey Explorer (WISE) infrared space telescope, launched in 2009, the second was taken by the Spitzer telescope, which was launched in 2003. And against their background, the James Webb Space Telescope photo looks incredibly clear.

Scientists hope that the new observatory will reveal many of the secrets of the universe, looking as far into the past as we have not yet looked.

The screen of Xiaomi Mi Band 7 turned out to

Not a day goes by without leaks about the latest Xiaomi Mi Band 7 fitness bracelet. This time, the device was photographed in a retail box, on the back of which is a list of main features. Below is the capacity of the battery.

Bold expectations that the Mi Band 7 will receive a 250 mAh battery have been dashed against the harsh reality – the fitness bracelet uses a 180 mAh battery. At least in the version with NFC, but it is unlikely that the battery capacity of the regular Mi Band 7 will be larger. However, even 180 mAh is noticeably more than 125 mAh in Mi Band 6. At the same time, we recall that the AMOLED screen size was 1.62 inches, while rumors attributed to the device a display with a diagonal of 1.56 inches. Xiaomi calls the screen of the Mi Band 7 a “Retina level display”.

What else do the inscriptions on the fitness bracelet box say? For example, the presence of a pulse oximeter and a proprietary voice assistant, support for more than 100 training modes, a sleep monitoring system and water protection (5ATM). The cost of the version with NFC is already known – $ 40. The official premiere of Mi Band 7 will take place on May 24.

Even Windows 11 has already been updated to Android 12.1. Microsoft has updated the subsystem Windows Subsystem for Android

Microsoft continues to develop the idea of ​​combining Windows and Android. Recently, the company announced the release of an update to the Windows Subsystem for Android subsystem for its current OS.

Even Windows 11 has already been updated to Android 12.1.  Microsoft has updated the subsystem Windows Subsystem for Android

One of the main innovations is the transition to Android 12.1 (12L). The current public version is based on Android 11. Initially, the update is only available through the Dev Channel. When it will become available to everyone is still unclear.

Microsoft notes that updating to Android 12.1 may result in some apps not running. She does not specify which ones, but it probably refers to some old programs.

The update also strengthens the integration of Android into Windows. For example, pop-up messages are first displayed as Windows notifications. The taskbar now shows if an Android app is accessing your microphone or location.

The company also states that Android apps should work better after waking the computer from standby. Instead of restarting, they should just resume where they left off.

It turned out that even a turned off iPhone can

Researchers at the Technical University of Darmstadt in Germany have found that the iPhone can be at risk even when turned off.

When iPhone is turned off, most wireless chips, including Bluetooth, NFC, and Ultra-Wideband (UWB), continue to work for up to 24 hours. So the phone can still be found through Find My and you can still access credit cards and digital keys. These wireless chips have direct access to the secure element and can be used to install malware on the iPhone even when iOS is down.

Wireless chips operate in low power mode (Low-Power Mode, LPM). This is not to be confused with Power Saving Mode, which extends battery life. LPM support is implemented in hardware, which means that this issue cannot be fixed with a software-side fix.

It turned out that even a turned off iPhone can be hacked

Researchers conducted a security analysis of the LPM features introduced in iOS 15 and found that the Bluetooth LPM firmware could be modified to run malware on the iPhone. These loopholes have not been previously considered and could allow hackers with system-level access to track someone’s location or trigger new features on the phone. The problem seems to stem from the fact that LPM features were designed with functionality in mind, and there seemed to be little attention given to possible threats outside of the intended applications.

Disabling Find My turns turned off iPhones into tracking devices, and the implementation in the Bluetooth firmware is not immune to manipulation. Tracking properties can be surreptitiously modified by attackers with system-level access.

Ars Technica notes that most iPhone users have nothing to worry about, since a jailbroken iPhone is required to infect third-party software. However, the security hole can be exploited by spyware such as Pegasus.

The results of the research were transferred to Apple, which did not comment on the situation.
