NASA has identified nine potential regions for the Artemis III mission to land near the Moon's South Pole. This will be the first human landing in this region, which may contain important resources, including water.

NASA is preparing for the first lunar landing in more than five decades. Currently, nine potential landing regions near the Moon's South Pole are being considered.

Writes UNN with a link to the website of the National Aeronautics and Space Administration.

NASA is continuing to develop the Artemis III mission to bring the first human crew to the Moon's South Pole. The agency recently selected nine regions near this unexplored area as possible landing sites. The areas will be analyzed in detail in scientific and engineering studies with the possibility of including new areas in future missions.

The regions of Artemis III's landing on the Moon have been clarified without priority:

The peak near Cabeus B

Haworth

Malapert array

Mons Mouton Plateau

Mons Mouton

Nobile Rim 1

Nobile Rim 2

de Gerlache Rom 2

Slater Plain

These regions have diverse geological characteristics and offer flexibility for mission accessibility. The lunar south pole has never been explored by a crewed mission and contains permanently shaded areas that may hold resources, particularly water.

The lunar south pole is a very different environment from where we landed during the Apollo missions. It offers access to some of the oldest landscapes on the Moon, as well as cold, shadowed regions that may contain water and other compounds

– said Sarah Noble, Artemis Lunar Exploration Manager at NASA Headquarters in Washington, DC.

To select these landing regions, a multidisciplinary team of scientists and engineers analyzed the lunar South Pole region. The selection process took into account scientific potential, the availability of a launch window, terrain suitability, communication capabilities with Earth, and lighting conditions.

“Artemis III will be the first time that astronauts will land in the lunar south polar region. They will fly a new lander to an area unique from our past Apollo experience. Finding the right places for this historic moment starts with identifying safe locations for this first landing, and then trying to combine that with opportunities for science from this new location on the Moon,” said Jacob Bleacher, NASA's chief scientist.

A study of 84 brains showed the death of somatostatin-inhibiting nerve cells at an early stage of Alzheimer's disease. This discovery may help to develop new methods for early detection and treatment of the disease.

It is important to detect Alzheimer's disease as early as possible. Current research by US scientists is making an important contribution to this.

After examining the brains of 84 deceased people (51 women, 33 men; the average age was 88 years), Seattle experts found out what happens to victims who have not yet experienced typical symptoms of Alzheimer's disease in everyday life.

Scientists have found that at an early stage of the disease, the so-called somatostatin-inhibitory nerve cells that send signals signaling the disease die.

These cells usually send signals that slow down the activity of other cells. The authors of the study suspect that the death of the above cell types may trigger further changes in the brain. This ultimately leads to the noticeable symptoms of Alzheimer's disease.

Early stages of Alzheimer's disease

According to the National Institutes of Health, the results of the study indicate "the very first changes" that occur slowly and quietly, "before any symptoms appear.

Tax changes include slow plaque buildup; damage to the cellular insulation that helps neurons send signals; and then the death of so – called somatostatin-inhibiting nerve cells.

The latter was particularly unexpected for the researchers, as science has previously suggested that Alzheimer's primarily damages nerve cells that send activation signals to other cells. Inhibitory nerve cells act exactly the opposite, they block other cells from performing their functions.

Somatostatin is a so-called peptide hormone. It is produced in various parts of the body – in the brain, as well as in the pancreas and digestive tract. Somatostatin plays an important role in the absorption of nutrients and can inhibit the release of various hormones, including insulin, glucagon, and gastrin.

The study of 84 brains showed that nerve cells that inhibit the release of this peptide hormone die at an early stage of Alzheimer's disease. Based on such findings, even better Alzheimer's drugs may be developed in the future that start acting as early as possible.

But so far, research is ongoing.

One of the challenges of diagnosing and treating Alzheimer's disease is that much of the brain damage occurs long before symptoms appear. Being able to detect these early changes means that for the first time we can see what is happening in the human brain in the early stages of the disease

– Richard J. Hodes, director of the National Institute on Aging, which is part of the NIH, comments on the study.

The Army+ app has added 5 new types of electronic reports for the Armed Forces of Ukraine. These include a Form 5 certificate, reports for leaving the garrison, for treatment, financial assistance, and leave after captivity.

The updated Army+ application now offers five more types of electronic reports for the Armed Forces of Ukraine. This was stated by the Ministry of Defense of Ukraine, UNN reports.

Details

We continue to digitize our processes by developing Army+ so that every serviceman receives services from the state simply, conveniently and without unnecessary hassle.

– Ukrainian Defense Minister Rustem Umerov said.

In particular, 5 new electronic reports are now available in the 2.0 update of the Army+ app:

• The Form 5 Certificate of Military Service is one of the most popular reports required to obtain state-guaranteed benefits or rights for military personnel and their families.
• A report on leaving the garrison, which will make it easier for our defenders to leave the garrison to solve personal issues or rest.
• To be released from duty for health reasons in case of medical treatment.
• For the payment of a one-time financial assistance after the conclusion of the first contract for the Armed Forces of Ukraine.
• And an application for leave after release from captivity, if the serviceman decides to continue serving in the Armed Forces.

In addition, the app has expanded the functionality of submitting reports. Specifically, the initiator now has the ability to withdraw a submitted report, and the commander can check the previous approver of the request.

The Army+ app has launched an online learning service with verified materials on military affairs. Courses on general training, field life, and unmanned systems are available, and new areas are planned to be added.

Ukraine's Ministry of Defense has codified the Safari HG-105M semi-automatic shotgun for use in the Defense Forces. The weapon can be used for close combat and FPV drone warfare.

The Ministry of Defense of Ukraine has codified and authorized the use of the semi-automatic shotgun Safari HG-105M in the units of the Defense Forces, UNN reports with reference to the Ministry of Defense.

According to the ministry, this rifle can be used as a small arms weapon during combat in confined spaces. And when using hunting ammunition with shot, it can be used as a tool to combat enemy FPV drones.

"The Safari HG-105M is a semi-automatic shotgun with a gas-piston mechanism and a detachable magazine. It is manufactured using bullpup technology. This is a weapon layout that reduces its overall length without reducing the length of the barrel. The use of this bullpup technology allows the center of gravity to be shifted to the center of the weapon, which reduces the load on the shooter during prolonged use," the statement said.

The weapon is designed to use 12-gauge ammunition with a magazine capacity of 5 or 10 rounds. The rifle weighs just over 4 kg, the Defense Ministry added.

He published a video from the “shahed's” camera, which was made public by the enemy

Russians use "chess" to conduct intelligence. This was written by the head of the Center for Countering Disinformation (CCD) Andriy Kovalenko on his Telegram channel, UNN reports.

"the Russians published footage from the shahed's camera. As I said earlier, the Russian Federation is now also using Shaheds as reconnaissance aircraft, and a significant number of them fly without a combat unit and are controlled remotely (smuggled Starliners, among others)," Kovalenko wrote.

Experts from the Kyiv Scientific Research Institute of Forensic Expertise believethat the Russians may install Starlink on attack drones to improve coordination between them, in particular during an attack.

Experts also found changes in the guidance system and coordinate system in these attack drones. Previously, there was a four-channel antenna, but now they have started using a 16-channel antenna. The electronic warfare jamming protection is equipped with an additional Russian-made unit.

Experts also note that there have been changes in the explosive part of the "Shahed". While in Iranian-made drones it was a projectile type, in drones assembled in Russia it explodes like a small aircraft bomb.

KFI experts described the technical features of North Korean missiles used by Russia to attack Ukraine. They identified differences in design, materials and markings compared to Russian missiles.

Since 2023, Russia has been using North Korean KN-23 or KN-24 aeroballistic missiles to strike Ukraine, as evidenced by research data. It was also found that missiles of this type differ from Russian ballistic missiles “Kinzhal” or “Iskander-M”. Oleksandr Vysikan, Chief Forensic Expert of the Department of Explosive Research, Artillery and Missile Weapons of Kyiv Scientific Research Institute of Forensic Expertise (Kyiv Scientific Research Institute of Forensic Expertise), told this to Suspilne, according to UNN.

According to the expert, the difference between the metal alloy of the DPRK and Russian missile engine is very different.

The Koreans (we are talking about the DPRK – ed.) use low-carbon (alloy – ed.), and Russian missiles use high-carbon. There are also “keyways” on the propulsion system – this is where the gargoyle is attached (a three-dimensional streamlined element on the rocket body that covers control wiring, pipelines and parts of systems – ed.), which contains cables that run from the rocket's flight control system to the tail section

– Vysikan explained.

He noted that the Russians also have such a design, but its structure is different.

“What we found is typical only for a Korean missile. In addition, we reviewed the footage published by the official media of the DPRK, where their leader (Kim Jong-un – ed.) walks near these missiles, and we clearly noticed this characteristic type of structure (of the missile – ed.),” said the expert of KFI.

He also said that one of the fragments had a serial number on it, which is not typical for such missile markings by the Russians.

On one side, the 9-digit number of the missile is written. In this case, the first 6 digits are preserved: “321 518”. We have already seen a similar 9-digit marking. They differed only in the last three digits. We can say that this is a serial number, which indicates that North Korean missiles of the same series are used. The Russians do not have such markings on the engine installation

– said Vysikan.

In particular, according to him, there is also a difference in the aerodynamic rudder and the missile's launcher. The experts of KFI counted 45 bolts on it, and according to them, this is different from the Russian Daggers and Iskanders.

“There is a distinctive difference. In Russian-made ballistic missiles, they are solid, and the shell is titanium. The base is different, where the aerodynamic surface is attached, which is also characteristic of these missiles. The drive, gearbox, and many other things are also characteristic, which points us to North Korean missiles,” says Vysikan.

He added that the institute's experts continue to study these missiles and other elements, and answered the question whether these weapons are more modern than Russian ones:

“These are older technologies. They differ from the Russian ones in terms of metal structure, welding seams of control units – this is not high-tech production, it is simpler and more affordable. However, these missiles have a large one-piece warhead, but its structure is completely different from the ones we studied in the Russian Kinzhal. It differs both in terms of metal composition and explosives.

Vysikan noted that the deviation of North Korean missiles from the initial target is large. He said that these weapons were used “a dozen times” to strike Kyiv and the region, but “KFOR does not keep statistics.” In addition, the expert added that a DPRK-made launcher is most likely to be used to launch these missiles, as Russian ones are not adapted for this purpose.

“For example, the Iskander missile has its own devices, how it docks with the launcher, where the flight mission must be recorded. And the sizes of the missiles are different, so you need a “native” launcher,” explained Vysikan.

Users will be able to receive digital extracts from the Unified Register of Weapons and control the validity of permits.

The Diia application will soon allow users to view information about weapons. Users will also be able to order a digital extract from the Unified Register of Weapons, which will help to monitor the validity of the permit in time. This was announced by Valeria Tkach, Deputy Director of Electronic Services Development at the Ministry of Digital Transformation, during a telethon, UNN reports.

"The Diia app will display information about the weapon," Tkach said.

According to her, it will be a register where you can view all relevant information about weapons: type, model, serial number, and status.

"As for weapons permits, it will contain information only on existing permits, their status: active, suspended or canceled. The validity period of the permit will also be indicated for control purposes to renew it in a timely manner," she added.

Tkach emphasized that it will also be possible to order an extract from the Unified Register of Weapons and the document will be in digital form.

Ukrainians have already filed almost 476 thousand applications for various types of weapons permits through the Unified Register of Weapons.

Scientists have developed an AI-based algorithm for analyzing paintings that allows determining whether a canvas belongs to a certain master

Scientists have taught artificial intelligence (AI) to see image details that are hidden from the human eye. Thanks to this, the neural network was able to establish that one of the most famous paintings by Raphael is not one hundred percent his work, writes UNN with reference to a study published in Heritage Science.

We are talking about the painting "Madonna with a Rose" (another title "The Holy Family with St. Joseph"), probably painted in 1518-1520. This canvas has long been a source of controversy among art historians – some experts doubted whether this painting was really created by Raphael.

Thanks to the use of AI, the researchers were able to find out that one of the faces in the painting, namely the face of Joseph, was painted by another artist. But the Madonna herself, baby Jesus, and St. John were painted by Raphael.

Researchers from the United Kingdom and the United States have developed a special analysis algorithm based on works that we know to be the result of the work of the Italian master.

"Using deep feature analysis, we used photographs of authenticated paintings by Raphael to train the computer to recognize his style in great detail, from brushstrokes, color palette, shading, and every aspect of the work," said mathematician and computer scientist Hassan Ugail of the University of Bradford in the United Kingdom.

In their work, the researchers used a modified neural network developed by Microscoft called ResNet50, combined with a traditional machine learning technique called Support Vector Machine. This method demonstrated 98 percent accuracy in identifying Raphael's work.

In the future, the researchers hope to use their findings to help art historians identify works of art.
