Solid oxide electrolysis cells (SOECs), a key technology for producing green hydrogen without carbon emissions, require a high-temperature “sintering” process to harden ceramic powders. Researchers at KAIST, led by Professor Kang Taek Lee from the Department of Mechanical Engineering, have successfully shortened this process from six hours to just 10 minutes, while also reducing the required temperature from 1,400°C to 1,200°C.

A team led by Prof. Yin Huajie from the Hefei Institute of Physical Science of the Chinese Academy of Sciences has developed a solar-powered system that produces green hydrogen directly from atmospheric moisture without relying on external water or energy sources.

In 2021, a group of scientists from China engineered the RoboFalcon—a bird-inspired flapping-wing robot with a newly engineered mechanism made to drive bat-style morphing wings capable of flight. While this bio-inspired robot performed well at a cruising speed, it was not capable of flying at lower speeds or achieving takeoff without assistance.

A hydrogen battery that operates at just 90 °C has been developed by researchers from Japan, overcoming the high-temperature and low-capacity limits of earlier methods.

Edit: I thought of editing the title, as well as mentionning that I didn’t like the tone of this article in the sense that it presents it ok to clear out forest for solar panels, and personally I believe it’s criminal, or something. I just thought it had some important info. And thank you Tobberone for your comment!

A research team from POSTECH and Seoul National University (SNU) has discovered a novel oxide material that can produce large quantities of clean hydrogen using only heat, without carbon emissions. The discovery, enabled by a new high-throughput computational screening method, was recently published in Advanced Science.

AI is a relatively new tool, and despite its rapid deployment in nearly every aspect of our lives, researchers are still trying to figure out how its "personality traits" arise and how to control them. Large learning models (LLMs) use chatbots or "assistants" to interface with users, and some of these assistants have exhibited troubling behaviors recently, like praising evil dictators, using blackmail or displaying sycophantic behaviors with users. Considering how much these LLMs have already been integrated into our society, it is no surprise that researchers are trying to find ways to weed out undesirable behaviors.

Researchers have assessed the potential to convert 15 weed species found west of Brisbane into biomass pellets, which were used as a solid biomass fuel.

In the paper, the scientists have highlighted how CoT monitoring has already proved its worth by detecting examples of AI misbehavior, such as when models act in a misaligned way "by exploiting flaws in their reward functions during training" or "manipulating data to achieve an outcome."

A research team led by Dr. Young-Min Kim and Dr. Byeong-Chan Suh from the Lightweight Materials Research Division at the Korea Institute of Materials Science (KIMS) has developed the world's first solid-state hydrogen storage material capable of storing and transporting hydrogen safely without the need for high-pressure tanks or cryogenic systems.

By 2040, the energy demands of the tech industry could be up to 25 times higher than today, with unchecked growth of data centers driven by AI expected to create surges in electricity consumption that will strain power grids and accelerate carbon emissions.

A research team has developed a novel and more cost-effective method for synthesizing ammonia decomposition catalysts. This new approach enables more efficient hydrogen production from ammonia and is expected to make a significant contribution to the realization of a hydrogen economy.

The researchers identified the following application areas, among others, as highly suitable for the environmentally friendly foams: the automotive sector for crash impact energy management, the construction sector as an insulating material, and the sports industry for the manufacture of sports equipment and shoe soles. The material also offers potential benefits in terms of moisture management and acoustics.

UCLA researchers have made a significant discovery showing that biological brains and artificial intelligence systems develop remarkably similar neural patterns during social interaction. This first-of-its-kind study reveals that when mice interact socially, specific brain cell types synchronize in "shared neural spaces," and AI agents develop analogous patterns when engaging in social behaviors.

The study analyzed data from 258 UK Uber drivers over more than 1.5 million trips between 2016 and 2024. This revealed a significant shift when Uber introduced a dynamic pricing algorithm in 2023. Passengers now pay more per trip, but drivers' earnings have declined. Adjusted for inflation, drivers' hourly income fell from over £22 to just over £19 before operating costs, and drivers are spending more unpaid time waiting for rides than before. Uber's commission has risen from around 25% to 29% and in some cases, Uber took over half the value of the fare.

They use stacked transparent color sensors, like Foveon camera sensors used to.

Aagesen singled out the role of the Spanish grid operator REE and certain energy companies she did not name which disconnected their plants "inappropriately... to protect their installations."

A team from MIT and the Woods Hole Oceanographic Institution (WHOI) has developed an image-analysis tool that cuts through the ocean's optical effects and generates images of underwater environments that look as if the water had been drained away, revealing an ocean scene's true colors. The team paired the color-correcting tool with a computational model that converts images of a scene into a three-dimensional underwater "world," that can then be explored virtually.

A Cornell-led collaboration has hit the trifecta of sustainability technology: The group developed a low-cost method to produce carbon-free "green" hydrogen via solar-powered electrolysis of seawater. A happy byproduct of the process? Potable water.

A team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed "fungi tiles" that could one day help to bring the heat down in buildings without consuming energy.

The robot is shaped like a small propeller and includes two small magnets. Under the influence of an external magnetic field, these magnets are attracted and repelled, causing the propeller to spin and generating enough lift to raise the robot off the ground. The flight path of the robot can be precisely controlled by modulating the strength of the magnetic field.

Scientists at Nanyang Technological University, Singapore (NTU Singapore), have developed an innovative solar-powered method to transform sewage sludge—a by-product of wastewater treatment—into green hydrogen for clean energy and single-cell protein for animal feed.

For most countries around the world, sourcing energy entirely from wind, solar, geothermal, and hydropower by 2050 would reduce their energy needs and costs, improve air quality, and help slow climate change, according to a study in Environmental Science & Technology.

A new test developed at the University of Illinois Urbana-Champaign can predict the performance of a new type of cementitious construction material in five minutes—a significant improvement over the current industry standard method, which takes seven or more days to complete. This development is poised to advance the use of next-generation resources called supplementary cementitious materials—or SCMs—by speeding up the quality-check process before leaving the production floor.

Testing showed that SUPER could safely fly through an obstacle course at 20 meters per second. The research team also found that it could follow a target, such as a human being, as it made its way through a forest, successfully avoiding trees, branches and other obstacles it met. They also found that because it is based on LiDAR, it can operate in low-light conditions as well.
