Plugging nanoscopic cracks to make hydrogen cleaner and cheaper

Researchers at Columbia University have created a novel approach to producing hydrogen from water electrolysis, utilizing ultra-thin, PFAS-free oxide membranes. This breakthrough reduces the industry's reliance on toxic chemicals and enhances energy conversion efficiency, paving the way for a cleaner and cheaper source of hydrogen.

Lichens and drones reveal dinosaur bones

Vibrant orange-coloured lichens are helping scientists discover dinosaur fossils in Canada. The team found that two lichen species colonise up to 50% of exposed fossil bones but less than 1% of surrounding rock fragments, providing a distinct spectral signature detectable from 30 metres above ground using drones.

New study shows high-resolution cmip6 models better capture long-term precipitation trends in high mountain Asia

A new study published in Journal of Climate reveals that high-resolution CMIP6 models more accurately simulate long-term summer precipitation trends in High Mountain Asia. The study found that higher resolution improves the simulation by reducing a wet bias, particularly over the southern margin and nearby regions.

A specific human gene can help the heart repair itself from heart attack or heart failure

A naturally occurring gene called Cyclin A2, normally silenced in humans, can make new functioning heart cells and aid in the heart's repair. The breakthrough discovery could lead to new techniques for repairing damaged hearts as an alternative to transplants or implanted cardiac devices.

Longer distances to family physician has negative effect on access to health care

A study of almost 10 million patients in Ontario found that those living over 30 km from their family physician were more likely to visit the emergency department for nonurgent reasons and had fewer visits with a family physician. The distance also negatively impacted preventive screening for certain cancers.
