Hydrogen plays an important role in society’s energy transition. For the technology to be used on a broad scale, effective hydrogen sensors are required to prevent the formation of flammable oxyhydrogen gas when hydrogen is mixed with air. Now, researchers at Chalmers University of Technology, Sweden, can present a compact sensor that can be manufactured on a large scale and is well suited to the humid environments where hydrogen is to be found. Unlike today’s sensors, the new sensor performs better the more humid it gets. “The performance of a hydrogen gas sensor can vary dramatically from environment to environment, and humidity is an important factor. An issue today is that many sensors become slower or perform less effectively in humid environments. When we tested our new sensor concept, we discovered that the more we increased the humidity, the stronger the response to hydrogen became. It took us a while to really understand how this could be possible,“ says Chalmers doctoral student Athanasios Theodoridis, who is the lead author of the article in the journal ACS Sensors.

Osaka Metropolitan University researchers discovered that the concentration of beneficial supersulfides increases significantly during the fermentation process of natto.

Singapore-MIT Alliance for Research and Technology’s (SMART) Mens, Manus & Machina (M3S) interdisciplinary research group, and National University of Singapore (NUS), alongside collaborators from Massachusetts Institute of Technology (MIT) and Nanyang Technological University (NTU Singapore), have developed an AI control system that enables soft robotic arms to learn a wide repertoire of motions and tasks once, then adjust to new scenarios on the fly without needing retraining or sacrificing functionality.

In a pair of new studies, ASU researchers and their colleagues show how DNA, the molecule of life, can be harnessed to faithfully store enormous volumes of data and provide powerful encryption.

New research from Hokkaido University suggests that the climate impact of tropical peatlands could be significantly higher than previously thought.

As federal policymakers weigh potential changes to how biomedical research is funded and regulated in the United States, a Virginia Tech scientist highlights the importance of preserving the nation’s ability to turn discovery into life‑saving therapies.

After noticing that eating peppermint leaves from his drink significantly relieved his sore throat, Flinders' Professor Krasimir Vasilev decided to explore whether its bioactivity could be converted into a durable coating using plasma technology. His team created a nanoscale peppermint‑oil coating that protects against infection, inflammation and oxidative stress, while remaining compatible with human tissue and suitable for medical materials.
