In an era where climate change looms large, the aviation industry—responsible for 3%–4% of global CO2 emissions and growing—faces immense pressure to go green without grounding our connected world. Aviation powers trillions in economic activity and millions of jobs, yet its reliance on fossil fuels spews not just CO2 but also NOx, particulates, and other pollutants that harm air quality and accelerate global warming. Enter hydrogen: a boundless, clean-burning fuel that could slash in-flight emissions to zero. But harnessing it means conquering storage challenges onboard aircraft. This survey dives into cutting-edge hydrogen tank technologies, exploring how to safely store gaseous or liquid hydrogen amid extreme pressures and frigid temperatures, all while integrating seamlessly into plane designs. By reviewing materials, structures, and innovations, it highlights hydrogen's role in aligning aviation with global sustainability goals, making eco-friendly flights not just a dream, but an impending reality.

A Korean research team, raising the question “Which OLED light color can actually improve memory and pathological markers in Alzheimer’s patients?” has identified the most effective OLED color capable of enhancing cognitive function using only light—with no drugs involved. The OLED platform developed for this study can precisely control color, brightness, flicker frequency, and exposure duration, suggesting potential future development into personalized OLED-based electroceuticals.

White oval squid (Sepioteuthis lessoniana sp. 2), known locally as shiro-ika, are medium-sized squids naturally distributed in the Indian and western Pacific oceans, flittering in and out of a wide range of different habitats – from shallow seagrass beds, over coral reefs, to depths of 100m along coastal environments. In such biodiverse zones, the squids encounter predators of all sizes and shapes, from seabirds flying overhead to sharks, tuna, and other cephalopods prowling under the sea.

Such a variety of threats calls for a large repertoire of survival strategies. Researchers from the Okinawan Institute of Science and Technology (OIST) have previously discovered how shiro-ika change color when moving between different shades of substrate – and now, the same team has painted a full picture of how the cephalopod employs a sophisticated range of camouflaging strategies to adapt to different environments and threats. “The wide variety of visual strategies used by the squid is surprisingly complex, especially considering that squid have traditionally been regarded as spending most of their lives in the open water column,” explains former OIST Visiting Researcher Dr. Ryuta Nakajima, “This discovery suggests that squid have a deeper behavioral relationship with the ocean floor than previously thought.”

A massive, multi-year scientific expedition determined that land use on tropical islands can shape water quality in lagoons and that rainfall can be an important mediator for connections between land and lagoon waters. The scale of this research is sigificant: the researchers assessed at algal tissue nutrients, water chemistry, and microbial communities at nearly 200 sites around the island of Mo‘orea, French Polynesia, and repeated this sampling over multiple years.

Researchers have developed the world’s first real-world head-to-head testing platform to determine whether commercial artificial intelligence (AI) algorithms are fit for NHS use to detect disease in a fair, equitable, transparent and trustworthy way, using diabetic eye disease as the first example. They say that it removes any biases that can come from companies wanting to deploy their AI software in clinical settings, putting all companies on a level playing field.
