A method that paves the way for improved fuel cell vehicles

Matter and energy from Science Daily Feed - Wed, 08/14/2024 - 9:45am
More efficient and longer-lasting fuel cells are essential for fuel cell-powered heavy-duty hydrogen vehicles to be an alternative to combustion fuelled counterparts. Researchers have developed an innovative method to study and understand how parts of fuel cells degrade over time. This is an important step towards the improved performance of fuel cells and them becoming commercially successful.

Exploring the structures of xenon-containing crystallites

Matter and energy from Science Daily Feed - Wed, 08/14/2024 - 9:45am
Noble gases have a reputation for being unreactive, inert elements, but more than 60 years ago Neil Bartlett demonstrated the first way to bond xenon. He created XePtF6, an orange-yellow solid. Because it's difficult to grow sufficiently large crystals that contain noble gases, some of their structures -- and therefore functions -- remain elusive. Now, researchers have successfully examined tiny crystallites of noble gas compounds. They report structures of multiple xenon compounds.

Rocks collected on Mars hold key to water and perhaps life on the planet: Bring them back to Earth

Space and time from Science Daily Feed - Wed, 08/14/2024 - 9:45am
Between July and November of 2022, NASA's Perseverance rover collected seven samples of sediment from an ancient alluvial fan in Jezero crater. While onboard analysis gave researchers some information about their origins, only detailed analysis on Earth can retrieve evidence of when water flowed on Mars and whether life arose there. Geophysicists had hoped to get these samples back by 2033, but NASA's sample return mission may be delayed beyond that date.

Nighttime light data shows inequities in restoring power after Hurricane Michael

Matter and energy from Science Daily Feed - Wed, 08/14/2024 - 9:45am
Using nighttime lightdata from NASA, remote sensing, official outage records and census information, a study reveals notable differences in power-restoration rates between urbanized and rural areas and between disadvantaged and more affluent communities after Hurricane Michael in Florida's Panhandle. Block groups with higher proportions of minorities, multi-family housing units, rural locations, and households receiving public assistance experienced slower restoration of power compared to urban and more affluent neighborhoods.

Leading AI models struggle to identify genetic conditions from patient-written descriptions

Computers and Math from Science Daily Feed - Wed, 08/14/2024 - 9:44am
Researchers discover that while artificial intelligence (AI) tools can make accurate diagnoses from textbook-like descriptions of genetic diseases, the tools are significantly less accurate when analyzing summaries written by patients about their own health. These findings demonstrate the need to improve these AI tools before they can be applied in health care settings to help make diagnoses and answer patient questions.
