A catalyst for more efficient green hydrogen production

Researchers have developed a new water-splitting process and material that maximize the efficiency of producing green hydrogen, making it an affordable and accessible option for industrial partners that want to convert to green hydrogen for renewable energy storage instead of conventional, carbon-emitting hydrogen production from natural gas.

Before horses, ass hybrids were bred for warfare

Before the introduction of the domestic horse in Mesopotamia, valuable equids were being harnessed to ceremonial or military four wheeled wagons and used as royal gifts, but their true nature remained unknown. According to a palaeogenetic study, these prestigious animals were the result of a cross between a domestic donkey and a wild ass from Syria, now extinct. This makes them the oldest example...

How to make sure digital technology works for the public good

The Internet of Things (IoT) is completely enmeshed in our daily lives, a network of connected laptops, phones, cars, fitness trackers -- even smart toasters and refrigerators -- that are increasingly able to make decisions on their own. But how to ensure that these devices benefit us, rather than exploit us or put us at risk? New work proposes a novel framework, the 'impact universe,' that can...

Being in space destroys more red blood cells

A world-first study has revealed how space travel can cause lower red blood cell counts, known as space anemia. Analysis of 14 astronauts showed their bodies destroyed 54 percent more red blood cells in space than they normally would on Earth, according to a new study.

Creating a reference map to explore the electronic device mimicking brain activity

Just like explorers need maps, scientists require guides to better understand and advance new technology. A neuromorphic device, which can mimic the neural cells in our brain, has lacked such a guideline and created headaches for scientists trying to understand their operational mechanisms. That is until now after a research group created a map that provides rational design guidelines for...

New study shows novel crystal structure for hydrogen under high pressure

Being the first element to form, hydrogen holds clues about the distribution of matter in our universe. Normally a gas, hydrogen exists as a solid under ultra-high-pressure conditions commonly found in the core of giant gaseous planets. However, the structures of solid hydrogen have remained elusive owing to difficulties in replicating such conditions experimentally. Now, a new study sheds light...

The first AI breast cancer sleuth that shows its work

Researchers have developed an artificial intelligence platform to analyze potentially cancerous lesions in mammography scans to determine if a patient should receive an invasive biopsy. But unlike its many predecessors, the algorithm is interpretable, meaning it shows physicians exactly how it came to its conclusions.

The free-energy principle explains the brain

The free-energy principle can explain how neural networks are optimized for efficiency, according to new research. This finding will be useful for analyzing impaired brain function in thought disorders as well as for generating optimized neural networks for artificial intelligences.
