A British startup, Deep, is setting out to revolutionize ocean exploration with its innovative approach to developing underwater habitats designed for long-term human presence on the seafloor. By enabling scientists to live and work on the ocean floor for weeks or even months, this groundbreaking initiative could unlock new opportunities for marine research and significantly enhance our understanding of the Earth’s vital marine ecosystems.

Despite the vastness of the world’s oceans, only a small fraction has been thoroughly explored. The majority of marine life—estimated to be 90%—resides in the deep sea, yet current diving technology severely limits researchers’ access to this underexplored environment. Traditional scuba diving restricts scientists to shallow depths and short excursions, while submersibles and remotely operated vehicles (ROVs) only provide fleeting glimpses of the ocean’s depths. In order to truly comprehend and protect our oceans, researchers need a way to immerse themselves in these environments for extended periods.

Researchers at the University of Toronto’s Faculty of Applied Science & Engineering have created an innovative class of nano-architected materials that are as strong as carbon steel yet as light as Styrofoam. Published in Advanced Materials, the research, led by Professor Tobin Filleter, highlights how machine learning was used to design nanomaterials with remarkable properties—high strength, low weight, and the ability to be customized for various applications. This breakthrough could revolutionize industries such as automotive and aerospace, where materials must balance strength and lightness.

Nano-architected materials, composed of tiny repeating units just a few hundred nanometers in size, are structured into complex 3D shapes known as nanolattices. These materials take advantage of the “smaller is stronger” principle, where nanoscale designs achieve superior strength-to-weight and stiffness-to-weight ratios compared to conventional materials. However, traditional lattice shapes often have sharp intersections and corners, creating stress concentrations that lead to premature failure.

In a groundbreaking development, researchers have designed a prototype rechargeable battery that functions in saltwater environments, offering a promising new energy source for oceanic and sea-based applications. This innovative saltwater-conductive yarn battery is not only flexible and durable but can also be integrated into fabrics or nets, providing power to marine devices such as safety equipment, fishing nets, and life vests.

Traditional batteries are highly sensitive to water, especially saltwater, due to the potential for damage and malfunction. However, this new design cleverly utilizes seawater as an electrolyte, turning its naturally occurring sodium, chloride, and sulfate ions into a functional energy source. This approach transforms seawater, typically a threat to conventional electronics, into a key component for generating power.

A glove-like robotic exoskeleton hand is helping pianists improve their playing skills without the risk of injury from overpractice. Drawing inspiration from traditional music teaching methods, a team at Sony Computer Science Laboratories in Tokyo has developed a device that moves individual fingers to guide complex hand motions. This innovation promises to support musicians in overcoming skill plateaus and enhancing their performance safely. According to researchers, just a single 30-minute session with the robotic exoskeleton can lead to measurable improvements in finger speed for trained pianists.

Achieving mastery in music, especially on an instrument like the piano, often requires countless hours of practice. However, research suggests that mere repetition isn’t always the key to further improvement. In fact, training alone accounts for less than half of skill development. As individuals reach a high level of proficiency, they often encounter a “ceiling effect,” where progress slows or stalls despite continued practice. This phenomenon challenges the idea that more practice automatically leads to greater skill.

SolidddVision smartglasses, developed by Soliddd Corp, are offering an innovative solution to people suffering from macular degeneration, a leading cause of blindness. Inspired by the eyes of a fly and powered by cutting-edge virtual reality (VR) technology, these glasses are changing the way we think about vision correction. First unveiled at CES 2025, they represent what is being called the “first true vision correction” for macular degeneration—a condition that causes central vision to blur as the macula, the part of the retina responsible for sharp central vision, deteriorates.

SolidddVision smartglasses blend augmented reality (AR) and virtual reality (VR) to create a groundbreaking way of restoring sight to individuals with damaged retinas. The glasses use a unique system of projecting multiple images onto healthy parts of the retina, a method inspired by the structure of a fly’s eye. This design allows the glasses to send light in parallel rays, simulating a complete visual picture by engaging the visual cortex. The result is an enhanced image that bypasses the damaged areas of the retina, helping users see more clearly.

Nuclear fusion—the process that powers stars—is often hailed as the ultimate solution for clean and sustainable energy. However, replicating this phenomenon on Earth comes with significant challenges, particularly when it comes to creating and maintaining the extreme conditions required for fusion reactions. To achieve fusion, scientists must generate and confine plasma, a hot, charged state of matter, at temperatures exceeding hundreds of millions of degrees Celsius. In these extreme conditions, atomic nuclei overcome their natural repulsion and fuse, releasing vast amounts of energy.

One of the biggest obstacles in realizing practical fusion power is maintaining this high-temperature plasma within a reactor without it cooling down or escaping. Tokamak reactors, doughnut-shaped devices that use powerful magnetic fields to confine plasma, have long been the leading technology in nuclear fusion research. However, a persistent challenge with tokamak reactors has been managing the plasma density, which is constrained by a phenomenon known as the Greenwald limit.

Insects possess an extraordinary ability to detect motion and navigate even in low-light environments, thanks to their highly specialized compound eyes. Now, researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a camera that mimics this biological marvel, achieving ultra-high-speed imaging while maintaining exceptional sensitivity in dim lighting.

The new bio-inspired camera offers impressive capabilities that surpass the limitations of traditional high-speed cameras. With a slim profile of less than 1 millimeter thick, it can be easily integrated into various systems and applications. The camera is capable of capturing 9,120 frames per second, providing clear, high-resolution images in low-light conditions—just like the insect eyes that inspired it.

Researchers have unveiled a groundbreaking software tool that allows for unprecedented insight into the 3D dynamics of biological structures. This interactive, dynamic tool provides researchers with advanced cutaway views of 3D images, making it possible to analyze the never-before-seen processes of embryonic heart development using optical coherence tomography (OCT) images.

Led by Shang Wang from Stevens Institute of Technology, the team’s work is set to significantly impact both the study of congenital heart diseases—one of the most common birth defects—and strategies for regenerating heart tissue after a heart attack. Their research, published in Biomedical Optics Express by the Optica Publishing Group, introduces the “clipping spline,” a new open-source software that offers an intuitive way to visualize complex 3D structures.

A research team at Northwestern University has achieved a groundbreaking milestone in chemistry by creating the world’s first two-dimensional (2D) mechanically interlocked material. This nanoscale innovation, resembling the interlocking links of chainmail, demonstrates exceptional flexibility and strength, offering great potential for applications in lightweight, high-performance body armor and other advanced uses requiring both toughness and flexibility. The findings, published on January 16 in Science, establish key firsts in the field, including the creation of the first-ever 2D mechanically interlocked polymer and the achievement of an unprecedented density of 100 trillion mechanical bonds per square centimeter.

The new material is a result of an innovative, efficient, and scalable polymerization process, opening the door for large-scale production. “We made a completely new polymer structure,” said William Dichtel, the corresponding author of the study and a professor of chemistry at Northwestern University. “It’s similar to chainmail in that it cannot easily rip because each of the mechanical bonds has a bit of freedom to slide around. If you pull it, it can dissipate the applied force in multiple directions.”

Scientists at the University of Stuttgart have made a groundbreaking advancement in synthetic biology by using DNA origami to control the structure and function of biological membranes. This innovative system has the potential to revolutionize drug delivery, offering a new way to efficiently transport large therapeutic molecules into cells, thereby paving the way for more targeted and precise treatments. The research, led by Professor Laura Na Liu and published in Nature Materials, marks a significant milestone in the application of DNA nanotechnology for medical and biological applications.

A cell’s shape and structure are integral to its biological function, embodying the principle of “form follows function.” This idea is not only prevalent in modern architecture but also fundamental in understanding cellular mechanics. In synthetic biology, mimicking this principle in artificial cells has proven to be a considerable challenge. However, the recent progress in DNA nanotechnology has provided a solution, enabling scientists to design transport channels that are large enough to carry therapeutic proteins across cell membranes.

This innovative, patent-pending wildfire defense system integrates advanced artificial intelligence (AI) with proven defense strategies. According to FireDome, the system can autonomously detect, protect, and suppress wildfires, operating off-the-grid for continuous monitoring and rapid response. It only activates when a threat is detected, ensuring a fast and efficient response without human intervention.

In a groundbreaking advancement, researchers have developed a transparent energy-harvesting device capable of capturing energy from both radio frequency (RF) waves and sunlight to power a wide array of wireless devices. This dual-source approach offers a more reliable and sustainable solution for energy harvesting, addressing the limitations of traditional systems that typically focus on just one energy source.

The new study, published recently, introduces an optically transparent rectifying metasurface system (RMS) that efficiently harvests RF energy while allowing the uninterrupted transmission of visible light. As the researchers explained, “In this paper, an optically transparent rectifying metasurface system is designed and validated for simultaneously harvesting RF energy while enabling the efficient transmission of visible light.”
