Worldwide, an estimated 110 million landmines remain buried in over 70 countries, a deadly legacy of past and ongoing conflicts. These hidden threats continue to cause devastation, resulting in 4,710 casualties in 2022 alone, with civilians accounting for more than 85% of the victims. Tragically, nearly half of these casualties were children. As new mines are deployed daily in conflict zones, the humanitarian crisis deepens, and the cost of their removal remains exorbitant—while a landmine costs only around $3 to produce, it can take up to $1,000 to safely remove each one.

The challenge of detecting and clearing these dangerous remnants of war is immense. Traditional methods, such as handheld metal detectors and ground-penetrating radar (GPR), are commonly used but often fall short, particularly when it comes to non-metallic landmines made of plastic. Metal detectors, for instance, can trigger false positives, while GPR can be ineffective in certain soil conditions or when faced with complex environmental factors.

In a groundbreaking revelation, Dr. Charles Buhler, a veteran NASA engineer and co-founder of Exodus Propulsion Technologies, has announced a revolutionary achievement in propulsion technology: a propellantless drive that can counteract Earth’s gravity, challenging conventional understanding of physics. This breakthrough promises to redefine space travel and propel humanity into a new era of exploration.

With extensive experience from iconic NASA missions such as the Space Shuttle and the International Space Station (ISS), Dr. Buhler and his team see this discovery as a monumental leap forward that will shape the future of space travel for centuries. “The most important message to convey to the public is that a major discovery occurred,” Dr. Buhler stated, highlighting the significance of their work.

If you’ve ever sat through a high school biology class, you’ve likely learned about the essential organelles that make up a cell—structures like the mitochondria, which produce energy, or the nucleus, which houses DNA. Traditionally, these organelles were understood to be membrane-bound compartments that each performed specific functions. However, this long-standing view of cell organization has been upended by an exciting new discovery: membraneless organelles, or biomolecular condensates.

For years, scientists believed that all cellular structures needed membranes to define their functions and keep everything in order. But in the mid-2000s, this theory was challenged when researchers began discovering that some organelles don’t require membranes to operate. These membraneless organelles, made up of proteins and RNA molecules, can form gel-like droplets inside cells that function as distinct biochemical compartments.

A new prototype water harvester developed by researchers at The Ohio State University is poised to offer a more efficient and portable way to extract drinking water from the air, especially in regions suffering from water scarcity. This innovative device, made from temperature-sensitive materials, could outperform traditional dehumidifiers by collecting more water from the atmosphere within 30 minutes and using roughly half the energy.

As more than 2 billion people around the world are estimated to lack access to clean drinking water, improving current methods of water collection could help make this vital resource more accessible, particularly in water-scarce regions. According to John LaRocco, lead author of the study and a research scientist in psychiatry at Ohio State University College of Medicine, access to clean water is not just essential for survival but also for improving national security, mental health, and sanitation.

In a groundbreaking development that could revolutionize water access in arid regions, researchers at the University of Nevada, Las Vegas (UNLV) have unveiled a new technology capable of pulling substantial amounts of water from the air in low-humidity environments. This innovation, which promises to help address water scarcity issues exacerbated by megadroughts, offers a sustainable solution for water-stressed areas like the American Southwest.

Published on October 22 in the Proceedings of the National Academy of Sciences, the research titled “High-yield atmospheric water capture via bioinspired material segregation” represents a significant advancement in atmospheric water harvesting technology. Led by UNLV mechanical engineering professor H. Jeremy Cho, the team’s breakthrough could transform how we think about water generation, particularly in regions where traditional water sources are dwindling.

Amazon has officially launched its drone delivery operations at its Tolleson, AZ, fulfillment center, marking a significant milestone in its Prime Air service. Customers in the West Valley Phoenix Metro Area can now receive packages within hours via drones, with access to more than 50,000 everyday essentials, including household items, beauty products, and office/tech supplies. Amazon claims this is its largest selection yet for fast drone deliveries, offering a wide range of items for quick, aerial transport.

This announcement follows Amazon’s decision to shut down its Lockeford, California testing zone, signaling a shift toward integrating drone technology into its operational network. The new Tolleson location will be the first to deploy drones directly from the fulfillment center itself, streamlining the delivery process and bringing Amazon one step closer to scaling its drone service.

A team of five high school students from Türkiye, known as Team Ceres, has developed an innovative device to address the devastating effects of drought on crops. Their creation, Plantzma, harnesses the power of plasma technology to enhance crop resilience and improve irrigation, offering a promising solution to the growing global food security crisis.

The team, consisting of Diyar, Adar, Dilvin, Mir Baran, and Beyza, was driven by their personal experiences witnessing the severe impacts of drought in their region. “My community is my inspiration,” says 17-year-old Beyza. Her hometown has recently seen a 40% decline in precipitation rates, compounded by rising pollution levels, leading to a staggering 80% loss in crop yields and a growing food shortage.
