The General Staff of the Armed Forces of Ukraine explained the reasons for the disruption of the precise time system in mobile phones during the air raid. The malfunctions are caused by the use of electronic warfare and GPS coordinates spoofing.

The General Staff of the Armed Forces of Ukraine explained the reasons for the disruption of the accurate time system in mobile phones during the air raid and recommended disabling the automatic time adjustment mode in the phone during the air raid, UNN reports .

“Attention, in the course of measures to repel air attacks by the Russian occupiers, electronic warfare means are being used,” the statement reads.

It is reported that, in particular, to increase the effectiveness of influence on the enemy, means of spoofing GPS satellite navigation coordinates are used.

“A side effect of this impact is a disturbance in the precise time system used by mobile phones in the automatic time update mode. In view of the above, it is advisable to disable the automatic time adjustment mode in the phone and take into account that the accuracy of satellite navigation systems may be disrupted during the announcement of air alerts,” – explained electronic warfare experts at the General Staff of the Armed Forces of Ukraine.

AddendumAddendum

On November 5, Ukrainians began complaining about the malfunctioning of their smartphone clocks: some users' clocks are “in a hurry.” In addition, the wrong location appears on the phones.

Berkshire Hathaway continues to sell off shares, including stakes in Apple and Bank of America. Warren Buffett's company has increased its cash reserves to a record $325 billion amid the upcoming US elections.

While investors are thinking about how to play the market on the eve of the US elections, Warren Buffett showed his “poker hand”. Reported by UNN with reference to Business Insider.

The 94-year-old boss of Berkshire Hathaway has refrained from endorsing Donald Trump or Kamala Harris, perhaps fearing a negative reaction for shareholders. At the same time, Buffett's conglomerate's third-quarter earnings provided new evidence of how the famous investor is removing some chips from the table.

Buffett's team sold $36 billion worth of shares and made purchases of only $1.5 billion, making it their eighth consecutive quarter as net sellers, Business Insider reports.

Between July and September 30, Berkshire Hathaway increased its cash, treasury bills, and other liquid investments to an unprecedented $325 billion (or $310 billion less nearly $15 billion in payables for the purchase of treasury bills).

Importantly, Berkshire cut its bets on Apple and Bank of America, two of its largest equity positions entering the quarter. It also cut its stake in the iPhone maker by 60% between January and September, reducing its value from about $174 billion to $70 billion.

At the annual meeting held in May last year, Buffett had already hinted that the cuts in the tech company made in the first quarter were partly motivated by tax consequences.

AddendumAddendum

After buying back $20 billion worth of Berkshire shares from the beginning of 2022 to June 30, 2024, Buffett did not buy back a single share last quarter. This is a strong signal that the investor no longer sees his company's shares as a bargain after they rose more than 20% this year to record highs.

The Shenzhou-19 spacecraft has successfully docked with China's Tiangong orbital station. The three-person crew, including the first female space engineer, met with the previous team for a five-day rotation.

The Chinese spacecraft Shenzhou-19 with a crew of three, including the country's first female space engineer, docked with the Chinese orbital station, UNN reports citing Xinhua.

Details

"China's Shenzhou-19 manned spacecraft successfully docked with the space station's rendezvous on Wednesday," the China Manned Space Program Administration (CMSA) reported.

At 11:00 a.m. on October 30 (Beijing time), the Shenzhou-19 spacecraft made a rapid automatic approach and docking with the space station's Tianhe core module's forward docking assembly.

"The launch has been recognized as a complete success," the publication writes.

Later, three taikonauts aboard China's Shenzhou-19 spacecraft entered China's Tiangong space station and met with three members of another crew, beginning a new round of crew rotation in orbit.

According to CMSA, the crew of the Shenzhou-18 mission opened the hatch at 12:51 a.m. Beijing time and greeted their successors.

According to CMSA, all six taikonauts will live and work together for five days to complete the scheduled tasks and shift work.

The Shenzhou-18 crew is scheduled to return from space on November 4 to the Dongfeng landing site in northern China.

Addendum

Early Wednesday morning (Beijing time), the Shenzhou-19 spacecraft was launched from the Jiuquan Cosmodrome in northwestern China using a Chang Zheng-2F rocket.

Canon has introduced a new RF-S7.8mm F4 STM Dual lens for 3D shooting with a 63-degree viewing angle. The device will go on sale in November 2024 at a price of $450, which is significantly cheaper than existing analogs.

Canon has officially announced the new RF-S7.8mm F4 STM Dual lens, first shown in June at Apple's WWDC 2024. UNN writes about it with reference to The Verge.

Details

The lens has stereoscopic elements squeezed into a body that is no larger than a traditional 2D camera lens. It was first introduced during a keynote at Apple's WWDC 2024 conference last June and is designed to work with the Canon EOS R7 as a more affordable tool for creators who create 3D VR content for headsets like Meta Quest 3 or spatial videos for Apple Vision Pro.

The company has not set a specific date for when the new 3D lens will be available, but says it will be sometime in November 2024, with an "estimated retail price" of $449.99. This is significantly cheaper than Canon's existing dual fisheye lenses designed to capture 3D video, including the RF5.2mm F2.8L Dual, which costs $1999, and the RF-S3.9mm F3.5 STM Dual, which costs $1,099.

Combining Canon's new 3D lens with the 32.5-megapixel EOS R7 digital camera, which starts at $1,299, brings the total cost of the kit to more than $1,700. However, this is still cheaper than Canon's more expensive 3D solutions, which start at $2,498 (and can go up to $6,298) when combined with the necessary camera hardware.

Canon's new 3D lens has an aperture range of f/4.0 to f/16, supports autofocus, and features a button and control wheel for separate manual focusing on the left and right sides. What makes it much cheaper than existing Canon 3D lenses is its limited field of view. More expensive Canon lenses are capable of capturing video and images with a 180-degree field of view – close to what the human eye can see – while the new RF-S7.8mm F4 STM Dual lens only covers a third of that angle, 63 degrees.

Using Canon's standard RF mount, the new lens has stereoscopic elements aligned in a straight optical path, resulting in its front lenses being only 11.8mm apart compared to the 60mm gap between the dual fisheye lenses on Canon's existing 3D lenses. As a result, Canon claims that the strongest 3D effect will be achieved when shooting subjects that are between 6 and 20 inches away from the lens. If you use it to shoot more distant subjects, the 3D effect will be less pronounced.

Images and videos captured with this lens need to be processed before they can be viewed with a virtual or augmented reality headset, either with the EOS VR plug-in available for Adobe Premiere Pro or with Canon's own EOS VR Utility software available for Mac and PC. Both tools require a paid subscription, but can generate 180-degree 3D, VR, or spatial video content.

The state-owned online service Diia has passed the 21 million user mark. The app is the second most popular Ukrainian app in the AppStore after Google.

More than 21 million Ukrainians are already using the Diia online public service, Deputy Prime Minister for Innovation, Education, Science and Technology Development and Minister of Digital Transformation of Ukraine Mykhailo Fedorov said on Wednesday in Telegram, UNN reports.

21+ million Ukrainians already use Diia! We are growing every day. In January, we passed the 20 million mark and are scaling further. We consistently rank second after Google in terms of popularity among Ukrainian apps in the AppStore

– Fedorov wrote.

According to him, with Diia, Ukrainians get married, start businesses, buy new housing and restore destroyed ones, save time and gradually forget about photocopies. Thus, according to the service, 600+ couples have already gotten married on Diia, 6,700+ couples have applied for marriage on the service, and 1,300,000+ have proposed to each other.

"Diia has become a state superapp that is hard to imagine life without. On the day of Diia's launch, we monitored the number of downloads and authorizations, and then we dreamed of the first million users. Five years have passed, and now we see 21,000,000 on the dashboard, which is a great result that motivates us to move forward and digitalize further," he said.

The Australian Ministry of Defense has canceled a multibillion-dollar military satellite project with Lockheed Martin. Instead of a single-orbit system, the country will focus on developing a multi-orbit system to improve defense capabilities.

Australia has canceled a multibillion-dollar military satellite project with Lockheed Martin (LMT.N). According to a statement from the country's Ministry of Defense, the military will instead shift its focus to a multi-orbital system. UNN writes about this with reference to Reuters.

Details

The project to launch a single-orbit satellite with Lockheed Martin, which was supposed to provide Australia's first satellite communications system with sovereign control over the Indo-Pacific Ocean, was canceled.

Due to the accelerated development of space technology and the evolution of threats in space since the project began, the Ministry of Defense assessed that a single-orbit geostationary satellite communications system would not meet strategic priorities

– the Australian Ministry of Defense said in a statement.

Instead, Australia will prefer a multi-orbital system to increase the resilience of the Australian armed forces.

In a radio interview with the Australian Broadcasting Corporation, Prime Minister Anthony Albanese said that while Australia's defense budget is growing, his government is prioritizing its procurement.

Empa researchers visualized the process of amyloid β protein accumulation in the brain associated with Alzheimer's disease. The observation lasted 250 hours and showed how second-generation fibrils are formed.

Empa researchers have recently been able to visualize the “abnormal” accumulation of amyloid β proteins in the brain, a process associated with Alzheimer's disease. Scientists hope that the result will open up new methods of diagnosing the disease.

Writes UNN with reference to Science Daily.

Alzheimer's disease affects more than 55 million people worldwide. Treatment of such disorders is still one of the biggest challenges facing modern medicine. The accumulation of amyloid plaques in the brain plays a significant role in the development of the disease.

Misfolded proteins stick together to form fiber-like structures. However, it was not yet entirely clear how these fibrils are formed.

Alcohol consumption is widespread in nature, as almost all ecosystems have ethanol – studyOctober 30 2024, 10:54 AM • 108963 views

Recently, a team led by Empa researcher Peter Nirmalraj from the Empa Transport at Nanoscale Interfaces lab and scientists from the University of Limerick in Ireland were able to show how this process works using a particularly powerful visualization technique.

ExplanationExplanation

The focus is on the processes observed on the surface of amyloid fibrils, i.e. structures in the brain formed by oligomers – soluble proteins that are highly toxic to neurons and assemble into dense fibers. Scientists have identified a special subtype of superproliferator proteins among them.

For reference

Aβ42 is considered to be one of the main factors that trigger Alzheimer's disease.

Incorrectly folded proteins lead to the formation of new oligomers on the surface of existing fibrils during secondary nucleation (when mature fibrils catalyze the formation of new oligomers).

Aβ is formed from a larger transmembrane precursor protein (beta-amyloid precursor, PBA) with a molecular weight of 100-140 kDa, which performs trophic and protective functions.

According to the “amyloid hypothesis,” beta-amyloid forms neurotoxic soluble oligomers for reasons that are not fully understood. According to numerous studies, beta-amyloid aggregates, including oligomers, have a detrimental effect on nerve cells, disrupting their normal functioning. This creates conditions for the development of Alzheimer's disease.

What the new observation achieves

The mechanism of how the protein building blocks come together to form second-generation fibrils, as well as their shape and structure, were previously unclear.

Recent imaging brings us one step closer to a better understanding of how these proteins are distributed in Alzheimer's brain tissue.

The researchers were able to observe the process of fibril formation in real time, from the first moments to the next 250 hours. This was made possible by a new technique: proteins are analyzed unchanged in saline, which is much closer to the natural conditions of the human body.

“This work brings us one step closer to better understanding how these proteins are distributed in Alzheimer's brain tissue,” says Nirmalraj, an Empa researcher. He hopes this will eventually lead to new ways of diagnosing the disease.
