A young man has been arrested and is awaiting trial following using the AirDrop to send a bomb threat to other passengers on a flight from American Airlinesus United States.

According to information from the local newspaper KTSMthe young man was using AirDrop to share a file from a device named “I have a bomb” (“I have a bomb”, in direct translation). This was made possible by renaming the device in Settings, so users didn’t even need to AirDrop to see the bomb threat.

A statement from the Texas Department of Public Safety was shared on Twitter:

The flight was taxiing before takeoff when the threat was made. Because of this, the procedure was interrupted and passengers had to leave the aircraft. The young man then confessed to what he had done, in addition to evidence of the action being found on his iPhone.

Widely used in the Apple ecosystem, AirDrop is a technology for quickly sending and receiving files between devices (iPhones, iPads and Macs). It is a very useful feature in many cases, but it is also used for malicious actions.

Precisely because of the problems involving the feature, Apple implemented with iOS 16.2 a feature that sets a 10-minute limit for AirDrop to receive requests from anyone; following this deadline, the system automatically reverts reception to “Contacts Only”, providing a little more privacy.

Codemasters and Electronic Arts are giving players access to the Alfa Romeo F1 Team 2023 C43 car through EA SPORTS F1 22 today. This in-game premiere is available to all finishers* in Time Trial mode ahead of the FORMULA 1 ARAMCO PRE-SEASON TESTING 2023 event, which begins later this week.

The striking red and black livery that Valtteri Bottas and Zhou Guanyu will drive in the 2023 FIA Formula One World Championship is an evolution of last year’s model, which finished 6th in the 2022 Formula 1 Constructors’ Championship – its best result in more than one Decade.

“Pre-season testing is a highly anticipated moment on the Formula 1 calendar and the first opportunity for fans to see how the new cars fare on the grid,” said John Merchant, F1 Global Brand Director at EA SPORTS. “We are excited to be part of the 2023 restart and give our players the opportunity to race and test the C43 for the first time.”

“The fans mean everything to us and giving them the opportunity to drive our new Alfa Romeo F1 Team C43 before they see it in action on the track is something that has never happened in the official F1 video games.” , said Alessandro Alunni Bravi, CEO of the Sauber Group and representative of the Alfa Romeo F1 Team. “We’re proud to be at the forefront of this groundbreaking approach, but that’s not all: we have a lot more in store that we have planned for the season and we can’t wait to show it all off .”

Additionally, starting March 2nd, EA SPORTS F1 22 will be added to The Play List, making the game available to EA Play and Xbox Game Pass Ultimate members. New players on Xbox, PlayStation and PC will be able to enjoy the thrill of Formula 1 with the most authentic recreation of the pinnacle of motorsport.

Scientists have identified the exact point at which healthy brain proteins collide with the tangled mess often associated with Alzheimer’s disease.

Researchers at the University of California Santa Barbara (UCSB) hope the new laboratory technology behind this discovery can be used to study the “unprecedented” early stages of several neurodegenerative diseases.

Tau proteins are abundant in the human brain. At first, these proteins look like little pieces of string inside neurons. When they fold and connect together with structural elements called microtubules, they create a kind of skeleton for brain cells that help them function properly.

Abnormally tangled tau proteins are a sign of many, but not all, cases of Alzheimer’s disease.

In this complex condition, known as neurofibrillary tangles, tau proteins are suspected of choking neurons from the inside out, interfering with cell function and ultimately leading to cell death.

Other experts argue that tau tangles are not toxic at all, but are in fact protective in nature, produced in response to some other underlying issue.

Being able to watch tau as it entangles in the lab might help researchers elucidate the protein’s role in brain degeneration. It might also be a great model for testing upcoming treatments.

And a multidisciplinary team of scientists at the University of California, San Francisco, has proposed a way to do just that.

With just under a volt of electricity, the researchers showed that they might spark an out-of-control struggle between a specific type of tau protein.

This stream is designed to mimic the molecular signals that naturally cause tau proteins to “hyperfold” in the brain, allowing researchers to monitor in real time as tau proteins pass a critical “tipping point” and switch from a healthy to a diseased state.

And when this line is crossed, entanglements quickly form.

“This method provides scientists with a new way to simultaneously stimulate and monitor dynamic changes in a protein as it goes from good to bad,” explains biochemist Daniel Morse, of the University of California, San Francisco. Because we can trigger and fine-tune the process, we can use this system to see which molecules can interrupt or prevent certain stages of folding and assembly.”

Tau proteins include a range of multiple soluble variants, but the type used in the current study is called K18, and it is a basic peptide containing a microtubule-binding domain.

Interestingly, the researchers found that when K18 was exposed to an electrical voltage over a long period of time (hours or days), it triggered a rapid and irreversible conflict.

However, even following only 15 minutes of short exposure, the tau proteins began to aggregate into knots, albeit easier to untangle with the reverse voltage.

This may be a sign that tau conflict might develop over time, just as symptoms of Alzheimer’s disease appear to be.

The transition from healthy to diseased tau protein might be “gradual, rather than the result of a one-or-nothing switch,” the researchers wrote.

This is an interesting insight into K18, but there are many other forms of tau that are sometimes linked to Alzheimer’s disease.

The way these other proteins fold and aggregate and the implications for cell activity can now, in theory, be studied using similar techniques.

The study was published in the Journal of Biological Chemistry.

According to information gathered by Digital Chat Station, the Black Shark 6 line is already in the full development process. In the view of several people who have access to the manufacturer’s plans, the presentation of the devices should take place in the first quarter of this year.

In addition, the smartphones must share a series of specifications, such as the 2K resolution AMOLED screen and which also supports a refresh rate of up to 144 Hz.

The smartphones of this new line should also have in common the processor Snapdragon 8 Gen 2and it can work on variants that have up to 16 GB of RAM and 1 TB of internal storage.

In the photographic field, the Black Shark 6 may have a Sony IMX686 main sensor, while the Pro variant may adopt a more powerful option to have this detail as a differential.

Stereo sound and ceramic construction are elements that will still be shared between the devices, as well as the 5,000 mAh battery with support for 120W fast charging.

The two devices should gain reinforcement in the heat dissipation system and this will not impact the final design, which will continue to have triggers, RGB LED and other gamer elements.

Finally, the DCS says that there is still no price range for the devices, but he believes that the manufacturer should not implement a drastic change in this regard.
