NASA Develops Device That Can Detect Even the Slightest Movement of Victims Trapped Under Debris
NASA has developed a groundbreaking device capable of detecting the faintest movements of human bodies trapped under rubble after disasters such as earthquakes, avalanches, and building collapses. This innovative technology, named FINDER, has already proven its life-saving potential. It was successfully deployed in 2023 to help rescue survivors buried beneath debris after the devastating earthquakes in Turkey and Syria. The device is the result of a collaboration between the U.S. Department of Homeland Security and NASA’s Jet Propulsion Laboratory (JPL). It was designed specifically to locate people who are alive but unable to communicate their presence to rescuers. How FINDER Works FINDER, which stands for Finding Individuals for Disaster and Emergency Response, utilizes highly sensitive microwave radar sensors that can detect extremely subtle biological signals. When pointed at collapsed structures or snow-covered areas, the device emits low-power microwave signals that penetrate through debris and reflect back. These reflections allow FINDER to “see” the tiny movements associated with a person’s heartbeat or breathing, even through concrete, metal, or other dense materials. Unlike conventional search methods, which rely on sound detection or trained dogs, FINDER can sense movements as slight as a millimeter. This means it can identify living individuals who are unconscious or unable to call out. According to NASA, the technology was originally inspired by tools used to monitor astronaut health and spacecraft integrity. After the catastrophic 2010 earthquake in Haiti, researchers recognized the need for better search-and-rescue equipment that could speed up the discovery of survivors trapped under collapsed buildings. Since then, FINDER has been refined and eventually released commercially so that emergency response teams worldwide can integrate it into their disaster toolkits. Proven Success in Real Emergencies During the earthquakes that struck Turkey and Syria in February 2023, NASA dispatched FINDER units along with trained operators. The devices helped local and international rescue teams locate survivors in the crucial hours after the initial tremors. The technology was credited with detecting signs of life in situations where conventional search methods were struggling, such as thick layers of debris or unstable structures. NASA also tasked its Earth observation satellites to capture high-resolution images of the affected regions. These satellite images were shared with humanitarian agencies and governments to help assess damage, plan rescue operations, and prioritize the deployment of resources. More Than Just One Device FINDER is not the only example of NASA’s technology helping to save lives after disasters. The agency has previously used tools such as the EMIT instrument aboard the International Space Station. EMIT is primarily designed to analyze atmospheric dust and gases, but it can also be repurposed to detect chemical leaks or air quality hazards in disaster areas. Moreover, NASA’s satellite data is regularly used by experts to assess the risk of aftershocks following a major earthquake. By analyzing subtle shifts in the Earth’s crust and ongoing seismic activity, scientists can better predict whether additional quakes might occur, helping to protect both survivors and emergency crews. Technology Bridging Space and Earth The development of FINDER illustrates how technology originally created for space exploration can find powerful applications here on Earth. The same expertise used to design systems that monitor astronauts’ vital signs or detect leaks in spacecraft cabins can be adapted to protect people in the aftermath of natural disasters. NASA and its partners emphasize that the humanitarian use of these innovations is central to their mission. In addition to rescue applications, NASA’s Earth Science Division maintains a suite of Earth-observing satellites that track storms, wildfires, droughts, and other hazards in near real-time. These data are freely shared to help communities prepare and respond. A Vital Role in Disaster Preparedness Experts say devices like FINDER are becoming increasingly important as climate change and urbanization increase the frequency and impact of natural disasters. Faster detection of survivors improves their chances of survival and allows rescuers to focus their efforts where they are most needed. NASA’s ongoing commitment to transferring technology from space science to practical tools on Earth underscores the agency’s broader mission: to advance knowledge for the benefit of humanity. As one NASA spokesperson put it, “Every life we save using this technology shows how the investment in science and exploration can return hope and resilience when people need it most.” With the continued refinement of devices like FINDER and the growing use of satellite data, scientists and engineers are helping to ensure that even the most catastrophic events can be met with more effective, life-saving responses.

Scientists Develop Bubble Wrap Gel That Can Produce Drinking Water From Air
In a groundbreaking advance that could transform access to clean drinking water around the world, scientists at the Massachusetts Institute of Technology (MIT) have developed an innovative gel that looks like bubble wrap and can harvest water vapor from the air—without relying on electricity or solar power. The remarkable new material has been hailed as a potential game-changer for arid regions where clean water is scarce or completely unavailable. According to a report published in the prestigious journal Nature Water, the device uses a simple but effective design: the gel is sandwiched between two glass panels. During the night, when temperatures are cooler and relative humidity increases, the gel absorbs water vapor from the surrounding air. By morning, the vapor condenses into liquid water, collecting on the interior surface of the glass. How It Works: Cooling Without Energy What makes this technology particularly noteworthy is that it leverages passive cooling principles rather than requiring any external energy source. The outer surface of the glass is treated with a special coating that allows it to remain significantly cooler than the ambient air. Because cooler surfaces attract moisture from warmer air, the water naturally condenses on the glass without mechanical refrigeration or solar thermal systems. This process, known as radiative cooling, essentially allows the surface to radiate heat into the sky and drop in temperature relative to the environment. The combination of radiative cooling and the moisture-absorbing gel means water harvesting can occur reliably—even at night or during overcast conditions—making it dramatically more versatile than other water collection systems that depend on sunlight or electrical power. Works in Extreme Heat To demonstrate its effectiveness, researchers tested the gel-based device in Death Valley, California, one of the hottest and driest places on Earth. Remarkably, even under extreme heat, the prototype successfully produced enough pure drinking water to fill a glass each day. Importantly, the collected water was clean and did not require further treatment before consumption. MIT scientists believe this ability to operate without electricity or solar panels could make the technology especially impactful for remote communities, refugee camps, or disaster zones where infrastructure is limited or damaged. Potential to Help Solve the Global Water Crisis The global water crisis affects billions of people. According to the United Nations, over 2 billion individuals lack access to safe drinking water, while climate change and population growth are intensifying shortages. Traditional water collection technologies, such as desalination or mechanical dehumidifiers, require substantial energy inputs, specialized equipment, and maintenance, which can be prohibitively expensive for under-resourced communities. In contrast, MIT’s bubble wrap gel can be produced in small, portable units that are inexpensive and easy to deploy. The materials themselves are relatively low-cost, and the system is designed to require minimal upkeep. This combination of affordability, simplicity, and reliability makes the technology particularly promising for humanitarian applications. How It Compares to Other Solutions Existing water-harvesting systems often rely on photovoltaic panels or electricity to power fans and cooling mechanisms. While effective in some regions, these methods have limitations: They may not function at night or in cloudy weather. They require batteries or grid power, adding cost and complexity. They are harder to scale down for small households or individuals. By contrast, MIT’s gel-based system operates passively in almost any climate, day or night, without generating emissions or using fuel. This makes it environmentally sustainable and highly adaptable. Next Steps for Deployment The researchers are now working to refine the design for large-scale manufacturing. One of the primary goals is to increase the daily water yield so that each unit can provide more water for multiple people. Scaling production could also drive costs down further, making the technology even more accessible in developing regions. The team envisions future applications including: Rooftop installations in villages with water scarcity. Emergency relief kits for drought-stricken areas. Compact personal devices for hikers, campers, or military personnel operating in remote locations. A Beacon of Hope MIT’s scientists emphasize that while this new gel is not a silver bullet for all water challenges, it represents a critical step forward in developing affordable and sustainable solutions. In a world where access to clean water can determine health outcomes, economic development, and even geopolitical stability, technologies like this bubble wrap gel could provide a beacon of hope to millions in need. As the climate crisis deepens and traditional water sources become less reliable, such innovative approaches will be essential to securing a future where everyone has enough safe water to drink.

TikTok Preparing to Launch New App Version for U.S. Users Amid Potential Sale
TikTok, the globally popular video-sharing platform, is preparing to roll out a new version of its app specifically designed for U.S. users as it navigates the uncertainties surrounding its potential sale in the United States. According to a report by the prominent technology and business news website The Information, cited by the British news agency Reuters, TikTok plans to release this new version on September 5. However, users will eventually be required to download the updated app if they wish to continue using TikTok’s services. While the existing version will remain operational until March 2026, these timelines are still subject to change depending on regulatory developments and business decisions. The report comes at a time of renewed scrutiny and negotiations over TikTok’s ownership in the U.S., a market with over 150 million users. Former U.S. President Donald Trump recently stated that he plans to initiate talks as soon as Monday or Tuesday regarding a possible agreement with China about the app’s future in the United States. Trump emphasized that the U.S. already has what he described as a “fully worked-out agreement” regarding TikTok’s sale, although he did not disclose specific terms or the identities of potential American buyers. Background of the Controversy The debate over TikTok’s ownership and operations in the U.S. has persisted for years. At the heart of the issue are concerns over data security and the Chinese government’s potential access to sensitive information about American users. TikTok’s parent company, ByteDance, is headquartered in Beijing, which has fueled bipartisan fears in Washington about possible misuse of user data and broader national security risks. In July, President Trump issued an executive order demanding that ByteDance divest TikTok’s U.S. assets by September 17. The order cited national security grounds, arguing that the app could potentially be used by China’s ruling Communist Party to gather personal data, track U.S. government employees, and shape public opinion through algorithmic recommendations. This new development follows earlier negotiations in which TikTok explored transferring its American operations into a new entity controlled by U.S.-based investors. In the first months of this year, discussions reportedly centered on forming a separate U.S.-registered company to operate TikTok independently from ByteDance’s China business. However, after President Trump imposed steep tariffs on Chinese goods, Beijing signaled reluctance to approve any deal that could be perceived as a forced sale under economic pressure. Uncertain Future and Potential Implications Analysts note that the planned launch of a new app version in the U.S. could be part of TikTok’s contingency planning as it faces legal and political challenges. If ByteDance fails to finalize a sale or secure regulatory clearance to continue operations, TikTok risks being banned in the U.S., which is its second-largest market after China. Industry experts also point out that even if an agreement is reached, implementing a technical separation between TikTok’s global and U.S. operations would be a complex undertaking. The app’s recommendation engine and data infrastructure rely on sophisticated algorithms developed by engineers in China. Creating an independent American version that complies with U.S. national security requirements could take considerable time and investment. Company Response and Public Reaction TikTok did not immediately respond to Reuters’ request for comment on The Information’s report, and Reuters itself has not independently verified the timeline or details of the new app’s planned launch. Meanwhile, many users and creators have expressed anxiety about the platform’s uncertain future. Over the past year, TikTok has become a crucial tool for influencers, small businesses, musicians, and educators to reach large audiences. According to some estimates, U.S.-based TikTok creators collectively generate billions of dollars in economic activity through advertising partnerships and branded content. A Broader Geopolitical Backdrop The escalating tensions over TikTok illustrate the growing technological rivalry between the U.S. and China. The debate around TikTok is part of a wider effort by American policymakers to limit Chinese technology firms’ influence over critical digital infrastructure and consumer data. In parallel, China has imposed stricter controls over the export of sensitive technologies, making it harder for companies like ByteDance to comply with foreign demands without government approval. Whether the proposed sale will ultimately proceed—and whether the September 5 launch of the new app will go ahead as planned—remains to be seen. For now, TikTok users in the United States face continued uncertainty as the world’s two largest economies clash over control of digital platforms that shape the culture and economy of the 21st century.

China’s Foreign Exchange Reserves Reach $3.3174 Trillion by End of June 2025
According to China Global Television Network (CGTN), citing data from the State Administration of Foreign Exchange (SAFE), China’s foreign exchange reserves surged to $3.3174 trillion at the end of June 2025. This marks an increase of $32.2 billion, or approximately 0.98 percent, compared to the reserves recorded at the end of May. China’s foreign exchange reserves represent the world’s largest stockpile of reserves held by any single country. These reserves include a mix of foreign currencies, gold, Special Drawing Rights (SDRs) allocated by the International Monetary Fund (IMF), and other reserve assets. The main purpose of maintaining such substantial reserves is to ensure financial stability, facilitate international payments, manage exchange rate fluctuations, and reinforce confidence in the country’s economic strength. Factors Contributing to the Increase Several factors contributed to the notable rise in China’s reserves during June. In particular, the weakening of the U.S. Dollar Index played an important role. Throughout the month, the dollar declined as major economies adjusted their macroeconomic policies and central banks signaled more cautious approaches to monetary tightening. Investors anticipated that slower rate hikes in the United States would make other assets more attractive, resulting in depreciation of the dollar relative to a basket of major currencies. Simultaneously, the global financial markets experienced an overall rise in asset prices. Stock markets in Europe, the United States, and parts of Asia rallied as investor sentiment improved amid easing inflation concerns and signs of stabilizing global demand. These trends had a positive valuation effect on China’s foreign assets, which are denominated in various currencies and instruments. SAFE explained that China’s economy has remained resilient and continues to grow steadily despite challenges in the international environment. Ongoing domestic reforms, technological innovation, and targeted government policies have underpinned economic momentum, strengthening the foundations that support the stability of foreign exchange reserves. China’s Commitment to Economic Stability Chinese authorities emphasized that a stable and sufficient level of foreign exchange reserves is vital to the country’s ability to weather external shocks and maintain currency stability. In recent years, China has made efforts to diversify the composition of its reserves, reducing excessive reliance on any single currency while enhancing liquidity and risk management. The steady increase in reserves reflects, in part, the country’s strong export performance, which has generated consistent trade surpluses. In addition, China has maintained policies to encourage foreign investment inflows, including portfolio investments in stocks and bonds. These inflows have contributed to the accumulation of reserves. Despite global uncertainties such as geopolitical tensions and the complex recovery of major economies, China’s policymakers remain confident in their capacity to sustain economic growth and safeguard financial stability. SAFE noted that going forward, the organization will continue to closely monitor changes in the international financial markets, optimize reserve management, and guard against potential risks. At the same time, authorities reaffirmed their commitment to maintaining a flexible and prudent monetary policy framework to balance growth objectives and financial discipline. Global Implications The size of China’s reserves has important implications for the global financial system. As the largest holder of U.S. Treasuries and other foreign sovereign debt, China exerts considerable influence over international capital flows and currency markets. Any significant shifts in China’s reserve management strategy, such as large-scale diversification away from the dollar, could affect yields and valuations worldwide. Analysts point out that the steady accumulation of reserves demonstrates not only China’s trade strength but also its determination to maintain a buffer against volatility. In times of global stress, such reserves can be deployed to stabilize the yuan, intervene in currency markets, or meet external obligations without undermining domestic economic objectives. Conclusion By the end of June 2025, China’s foreign exchange reserves had reached $3.3174 trillion, registering a monthly increase of $32.2 billion. This growth is attributed to the depreciation of the dollar, rising asset prices in global markets, and China’s resilient economic fundamentals. The country’s foreign exchange reserves remain the largest in the world, underscoring its capacity to manage risks and sustain confidence among investors and trading partners alike.
