COPD as a lung stem cell disease

Abnormal stem cells in COPD patients drive key features of the disease, including mucins that block airways and fibrosis and inflammation. Researchers have identified specific cells responsible for COPD pathology and are screening them against drug libraries to discover new treatments.

Two is better than one

A team of scientists has developed a new 2D catalyst that can improve the efficiency of water purification using hydrogen peroxide. The catalyst, composed of two co-catalysts on one nanosheet, was designed to increase the efficiency of the process without additional chemical treatment.

Logging threatening endangered caribou

A recent study by University of Guelph researchers found that logging in Ontario's boreal stands is threatening the population of endangered woodland caribou. The team analyzed video collars attached to 30 caribou, as well as GPS-tracking radio collars on wolves and caribou, to monitor their movements and find evidence of predation.

Economists find carbon footprint grows with parenthood

A new study found that households with children emit over 25% more carbon dioxide than childless households. Parents' concerns about the environment do not translate to a reduction in carbon footprint, but rather increased transportation and food consumption. This disparity is likely due to time constraints and the need for convenience.

Face up to eating disorders, and seek help

A recent study found that young adults in Australia are leaving it 'too late' to seek help for eating disorders due to various barriers. Concerns about autonomy, fear of being a burden, and perceptions of the illness's severity prevent many from seeking professional advice.

ECMO physicians offer guidance in the context of resource-scarce COVID-19 treatment

In the context of a resource-scarce COVID-19 treatment, ECMO physicians outline their approach to care and provide guidelines for medical centers to respond to patients' needs. The guidance emphasizes optimizing resource utilization to prioritize patients with severe respiratory failure but without other significant co-morbidities.

Journey to the center of the Earth

Scientists have successfully determined the density of liquid iron and sound propagation speed through it at extremely high pressures. They found the density of the molten outer core to be about 8 percent less dense than pure liquid iron, suggesting the presence of additional lighter elements.

Applying mathematics to accelerate predictions for capturing fusion energy

Scientists at Princeton Plasma Physics Laboratory have developed a new technique to predict fusion energy performance using advanced mathematical modeling. This approach combines millisecond behavior with longer-term forecasts, enabling accurate predictions of plasma temperature profiles and heat fluxes at significantly reduced computa...
