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.
