In APL Bioengineering, researchers use a machine learning algorithm to explore whether electroencephalography could be useful for connecting brain signals with limb movements in patients who have lost some or all their limb function. In tests, the researchers equipped patients with EEG monitors and asked them to perform simple movements, using their algorithm to classify the range of possible signals. They found they could detect the difference between attempted movement and no movement but struggled to differentiate between specific signals.

Metal single-atom catalysts (M-SACs) are highly attractive for proton-exchange-membrane water electrolysis (PEMWE), a clean and efficient hydrogen production method. However, in high-density M-SACs, metal atoms tend to aggregate, reducing catalytic activity and durability. Now, researchers from Dongguk University have developed a new synthesis method for M-SACs that prevents the aggregation of metal atoms, significantly improving the hydrogen production performance of PEMWE systems.

Hydrogen fuel cell heavy-duty trucks offer a cleaner alternative to diesel transport, but public support is essential for large-scale adoption. In a new study, researchers surveyed households in South Korea to measure willingness to pay for expanding hydrogen truck deployment. The results show strong public acceptance, with benefits exceeding carbon reduction costs, indicating the policy is socially profitable and supports long-term low-carbon transport transitions under national climate policy goals frameworks.
