Russia-Ukraine War Enters Fourth Year: Can Flamingo, Oreshnik Missiles, F-16 Jets and AI Drones Change the Balance?
On the 24th of this month, four years will be completed since Russia’s invasion of Ukraine. This war has continued without pause for four years, and there are still no visible signs that it will end. Negotiations between Russia and Ukraine are being held in Abu Dhabi under U.S. mediation. On Thursday, another round of these talks ended without any progress. If diplomacy is failing to deliver results, do the two countries possess such advanced weapons that could potentially tilt the balance of war in favor of either side? New Missiles: Flamingo vs. Oreshnik

China’s C919 Aircraft: A New Competitor in the Asia-Pacific Aviation Market
This scene is from the Singapore Airshow, where exhibition halls are filled with aircraft models, mock cockpit structures, and interactive displays. Everything from modern commercial airplanes to the latest aviation technology is on display. At the Singapore Airshow, one booth in particular has captured everyone’s attention—that of COMAC, China’s state-owned passenger aircraft manufacturer. The company’s passenger aircraft, the C919, made its first flight to Singapore two years ago. This aircraft has been developed to compete with the Airbus A320neo and the Boeing 737 Max, and it is also targeting markets outside China. The Asia-Pacific region is a rapidly growing aviation market. At a time when airlines are facing delivery delays and supply chain pressures, this airshow provides COMAC with an opportunity to prove itself as a potential rival to Airbus and Boeing in the Asia-Pacific. Willie Walsh, Director General of the International Air Transport Association (IATA), said: “I believe that at some point COMAC will compete globally, but it will take time. “Ten to fifteen years from now, we will be talking about Boeing, Airbus, and COMAC. Without a doubt, they will be major players in the future.” Walsh added that Asia-Pacific airlines can only achieve double-digit growth in 2026 if aircraft are available. According to him, “It is extremely frustrating for airlines that there is nearly a seven-year gap between ordering an aircraft and receiving it.” This is why COMAC is emerging as another option for Asia-Pacific airlines. At present, more than 150 COMAC aircraft are in operation within China. COMAC planes are also flying in Laos, Indonesia, and Vietnam. Brunei’s GallopAir has placed a large order for COMAC aircraft, and Cambodia is also planning to purchase around 20 planes. Subhas Menon, Director General of the Association of Asia Pacific Airlines, said: “There is a need for more suppliers so that the supply chain does not face disruptions. The problem with this industry is that the supply chain is dominated by a few companies, and sometimes just two.” He added: “We have been waiting for this for a long time. COMAC is a welcome addition. We need more suppliers, especially in the Asia-Pacific.” The company is in a strong position. The government support available to COMAC in emerging markets, along with comparatively cheaper aircraft, makes it attractive for airlines with limited capital. Mike Szucs, Chief Executive of the Philippine low-cost carrier Cebu Pacific, told the BBC: “We welcome new companies entering the market in the future. We strongly want a competitive environment in this sector. “COMAC still has to go through its certification process, and we expect that sometime in the 2030s it will become an attractive option for us and other airlines.” Along with expanding in the Asia-Pacific, COMAC is also trying to obtain European certification. Regulators are conducting test flights of the C919 aircraft. If the aircraft is approved, it will be allowed to be sold to European airlines. However, the road ahead is quite long. Regulators say that European certification could take until 2028, or even 2031. Adapting Chinese components, flight controls, and software to Western standards is also a technical challenge for securing international orders. Aircraft maintenance and repair systems are another hurdle for COMAC, as is pilot training. These are areas in which companies like Boeing and Airbus established structured systems decades ago. In the Asia-Pacific, COMAC faces competition not only from Boeing and Airbus but also from another manufacturer. This is Brazil’s aircraft maker Embraer, which has already established its presence in the region. Singapore’s low-cost airline Scoot, Virgin Australia, and Japan’s All Nippon Airways (ANA) are placing orders for Embraer aircraft. Nevertheless, Boeing and Airbus still maintain a strong foothold at the Singapore Airshow and across the region. Airlines that have long been frustrated by aircraft delivery delays are now receiving assurances from Boeing and Airbus that delivery schedules are set to improve. Mike Szucs of Cebu Pacific said: “It is good to feel that perhaps we can see light at the end of the tunnel.” Questions are also being raised about the number of aircraft COMAC can actually deliver. The company previously said that Chinese airlines had placed orders for 1,000 C919 passenger planes. However, only around a dozen aircraft have been delivered so far. Verifying these figures is also difficult because, unlike Boeing and Airbus, COMAC is a Chinese state-owned company. This means it is not required to publicly disclose its production, costs, and revenue. Until COMAC resolves some or all of these issues, it is highly likely that Boeing and Airbus will continue to dominate the skies of the Asia-Pacific.

NO WATER NO BRAIN
Water is the most essential nutrient for human survival, and the brain is one of the organs most dependent on adequate hydration. Nearly 85 % of the human brain is composed of water, which plays a critical role in maintaining its structure, supporting chemical reactions, and enabling communication between nerve cells. Even a mild deficiency of water—commonly known as dehydration—can significantly affect brain function, mood, and overall mental performance. Understanding how water deficiency impacts the brain highlights why regular hydration is vital for cognitive health.

UpScrolled App Review: A New Social Platform Breaking Digital Censorship
Since October 8, 2023, the war that Israel has been waging against Gaza has not only targeted people's lives and buildings, but it has also affected how truth is shared online. While Palestinians were recording the destruction of their lives through videos and photos, they also faced a hidden battle on social media. Big platforms used their systems to remove content, limit its visibility, and silence Palestinian voices through secret rules. This effort to silence Palestinians wasn't just a mistake—it was a clear attempt to cut them off from the world and strip them of one of the most powerful tools of the modern age. Because of this, there was a need for a new platform that could break through the information block and give a space where people could share without being controlled by money or politics. That's how the "UpScrolled" app was created at the end of 2023 and the start of 2024. It was designed as a response to the restrictions put on Palestinian content by big platforms like Meta and TikTok. Behind this project is Issam Hijazi, a Palestinian-Australian tech expert who has worked at companies like IBM and Oracle. He developed the app after his personal accounts were blocked and after he lost several family members in Gaza, in order to build a space that is free from political pressure. UpScrolled works like a short video sharing app, similar to TikTok and Instagram Reels, but with a key difference in how it handles content. While other platforms block certain types of political or humanitarian content, UpScrolled uses an open system that shows content based on what users are interested in and how they interact with it. It doesn't block words related to humanitarian or political topics. Within a few months, the app became very popular and made it into the top downloaded apps on Apple and Google. It ranked 11th in the US and 12th in the UK. This popularity shows how much people around the world want platforms where they can speak freely, especially as digital control over information about human rights and justice grows. UpScrolled isn't just an entertainment app; it's a project that supports the idea of digital democracy. Issam Hijazi used the slogan, "The voice of Palestine will never be restricted," and spread this message to people who are oppressed or ignored online. This app is an example of using science and technology as a way to peacefully resist, breaking through borders and reaching global awareness without being controlled by surveillance. With support from the US, Israel launched a two-year war on Gaza starting in 2023, killing over 71,000 Palestinians and injuring more than 171,000—mostly children and women. The war has destroyed nearly 90% of Gaza’s civilian buildings, and the UN has estimated the cost of rebuilding Gaza at about seven billion dollars. Around 1.5 million people have been forced to leave their homes. By February 2, 2026, UpScrolled had reached 2.5 million users. According to the Google Play Store and the Apple App Store, it has become the most downloaded social media app in the US and Canada, with growing interest in the UK, France, Germany, and Italy. UpScrolled's algorithm helps users find posts based on likes, comments, and shares, with time-based changes and some randomness, all shown in order. According to the app's website, there's no interference. The app looks like a mix of Instagram and Twitter, letting users share text, photos, and videos. It also allows private messaging. It's available for iOS and Android, with plans to expand further.

Eight reasons why women are unable to achieve satisfaction even after having sex
Understanding sexual expectations in people—especially in women—can sometimes be difficult. Even sexologists and doctors face challenges in this area. Much more work is still needed to understand this subject because many women are unable to enjoy sexual satisfaction even during romantic relationships. Some women even say that they have never experienced sexual fulfillment in their entire lives. There are many factors that contribute to sexual pleasure for women in relationships. These factors also include the thoughts that come to their minds and the physical and emotional effects those thoughts have on them. This report discusses eight factors that prevent women from enjoying satisfaction during sexual relations, leaving them feeling unfulfilled despite being in a romantic relationship. Bitter experiences of the past If a woman has experienced a violent or painful incident in the past that changed her perception of sexual relationships, it can create difficulties in her future relationships. In such cases, the affected woman is advised to talk openly with her partner or husband and share her past experiences. However, it can be difficult for any woman to discuss such topics with another person, even her husband or partner. In these situations, help from specialists can be sought. Dr. Hector Galván, head of the Madrid Institute of Psychiatry and Communication, says: “It is very difficult because memories of such bitter experiences are quite disturbing, and talking about what happened in the past can increase mental stress.” Fatigue Dr. Galván says that, according to his experience, most women are unable to achieve satisfaction during sexual activity due to fatigue. “Any body needs freedom and relaxation to achieve sexual fulfillment.” He adds that even if the body is tired, some sensations may still be felt, but for complete satisfaction it is essential that both body and mind are fully relaxed and free from all worries. Many women become exhausted from daily chores, household responsibilities, and caring for children. Despite not achieving sexual satisfaction due to fatigue, they often pretend to be satisfied. Psychologists say this should be avoided. They advise that couples should talk to each other to understand these issues and find solutions. Lack of communication During sex, we can guess to some extent how our partner is feeling, but it is not possible to fully understand their emotions. You may estimate from your partner’s sounds, movements, and expressions how they feel, but the better way is to tell each other about your feelings and how you are experiencing the moment. Experts say many women even find it difficult to tell their partner to change their sleeping or intimate style. They emphasize that you must tell your partner about your preferences and needs—only then will they be able to understand them. Lack of foreplay Dr. Galván says that in recent years there has been a growing trend toward spending more time on foreplay. Foreplay refers to the emotional, physical, or mental activities carried out before sexual intercourse to prepare for intimacy. However, the problem is not only about time but also about what should be done and how it should be done during foreplay. It would be better for women to clearly tell their partner before regular sex what they want and how it can be achieved. Dr. Galván says: “Women often tell us that men have no idea what to do or how to do it, but they are afraid to tell their partners because they think it might hurt their feelings or embarrass them.” Lack of sexual desire According to the British Department of Health, women may face mental stress at different stages of life such as during pregnancy, after childbirth, or during menopause. Stress, anxiety, side effects of medicines, or hormonal changes can also cause a decrease in sexual desire in women. All these factors can affect how a woman feels in her romantic relationship. The health department states that when a woman’s body produces less testosterone, sexual desire may decrease. This can also be due to problems in hormone-related glands. In such cases, experts advise consulting a doctor immediately. Imposing one’s will on others Experts say that when the Institute of Mindfulness and Dating reviewed the relationships of some couples complaining about lack of sexual satisfaction, it was found that some people impose their own wishes on their partner or force them to do what they themselves like. Therefore, it is important to keep both body and mind relaxed and free, and not try to impose one’s will. Pain during sex Another reason why women are unable to achieve sexual satisfaction is severe pain during intercourse. This condition is called “vaginismus,” in which the muscles of a woman’s vagina tighten. Due to this unnecessary contraction of muscles, a woman experiences intense pain during sex. According to the British Department of Health, this condition can sometimes make affected women less inclined toward sexual relations. Dr. Galván says: “This can also happen when women have negative feelings about sex or have suffered trauma during childbirth or surgery.” He adds: “When the brain sees something (sex) as punishment or pain, a woman’s desire decreases and she begins to avoid intimacy.” If there is vaginal dryness or infection, it is advised to consult a doctor. Problems in marital relationships Experts believe another major issue that reduces sexual desire in women is tension in marital relationships. Dr. Galván says: “Sometimes people come to us complaining about lack of sexual satisfaction, but when we examine the situation, we realize that the real problem lies in the couple’s mutual relationship.” He advises that if this is the case, it is very important to identify misunderstandings and conflicts causing tension in the relationship and to resolve them.
