Heated tobacco products make SARS‑CoV‑2 infection and severe COVID‑19 more likely

A study by Osaka Metropolitan University found that users of heated tobacco products had a higher rate of COVID-19 infections and severe cases requiring hospitalization or oxygen. Researchers analyzed data from 30,130 participants and discovered a significant association between heated tobacco product use and increased risk of SARS-CoV...

Synergistic iron carbide catalysts enable direct conversion of syngas into higher alcohols

Researchers at Dalian Institute of Chemical Physics have developed a new method to synthesize higher alcohols from syngas using synergistic iron carbide catalysts. The catalysts achieve a high oxygenate selectivity and produce a significant amount of higher alcohols, making this process a promising alternative for sustainable production.

More predictable renewable energy could lower costs

Researchers at the University of Adelaide have found that more predictable solar or wind energy generation can save millions of dollars in operating costs and prevent clean energy spillage. By analyzing six existing solar farms, they discovered that optimal locations changed when predictability was considered, leading to significant in...

Increasing education opportunities for girls could help reduce preventable deaths in children under five

A recent study by IIASA researchers found that maternal education, especially secondary education, significantly reduces under-five mortality rates in both rural and urban areas of India. The study analyzed data from the Indian National Family Health Survey and discovered a protective effect of maternal education on child mortality.

Use age, not weight, to screen for diabetes

A new study suggests that age, not weight, should be used to screen for diabetes, capturing the greatest number of people in all racial and ethnic groups. The approach identifies the greatest proportion of adults with prediabetes and diabetes and maximizes equity across racial and ethnic groups.

11 ways to improve airlines for customers

Research using artificial intelligence analyzed nearly 400,000 customer reviews to identify key themes and customer sentiment towards airlines. The study found that customers commonly complained about lost luggage, uncomfortable seating and flight cancellations, but praised in-flight entertainment, ground staff and business-class servi...

Wastewater to energy: new treatment process can improve biorefinery sustainability

Researchers at CABBI designed a new wastewater treatment process that simultaneously treats water and recovers biogas, reducing capital costs and energy usage. The process efficiently converts organic contaminants to biogas, achieving simultaneous energy recovery and wastewater treatment.

Framework helps local planners prepare for climate pressures on food, energy & water systems

A new framework developed by a multidisciplinary team provides guidance to local and regional planners to anticipate and prepare for the impacts of climate change on critical civic resources. The C-FEWS framework evaluates options and makes decisions related to specific local conditions, focusing on the nexus of food, energy, and water.

Attack from the gut

A new study published in Cell Reports shows that gut bacteria from the patient's own intestine can cause post-operative infections, which are often fatal. The liver plays a key role in controlling these spreading bacteria through special immune cells called innate lymphoid cells.

Ancient genomes reveal immunity adaptation in early farmers

Researchers found that a large genetic region responsible for immune responses showed rapid evolution and more Mesolithic hunter-gatherer ancestry, suggesting that genetic variants already present in Europe were passed down preferentially. This suggests that diversity in immune genes may be just as important as adaptation to lifestyle.

Why does a leukemic mutation not always lead to leukemia? A new clue from a mouse study at USC

Scientists from USC Stem Cell laboratory discovered a mechanism linking leukemic mutations to varying disease potentials, identifying RNA splicing regulator Rbm25 as a critical factor. The study found that over-contributing clones of blood stem cells produce excessive myeloid cells, leading to potential leukemia development.

Study: Mapping people’s knowledge of bees may aid in pollinator conservation

A recent study found that U.S. college students have low awareness of wild bee species, with their knowledge focusing primarily on honey bees and pollination services. The researchers suggest that education alone may not be enough to produce attitude and behavior change, and propose a novel approach using semantic network analysis and ...

Post-bariatric surgery exercise modulates brain regions associated with regulation of food intake

Exercise training after bariatric surgery alters brain networks associated with food intake and energy regulation. The study found that exercise increased connectivity between the hypothalamus and sensory areas, while decreasing links to the default mode network and salience network.

Integrate global natural history museum collections to provide a resource to decision-makers

A global approach is proposed to integrate natural history museum collections, providing a valuable resource for addressing global issues like invasive species, biodiversity conservation, and climate change. The vast collections held by museums worldwide are becoming increasingly important in policy-relevant research.

Scientists discover a novel origin of abiotic oxidants on early earth: minerals

Researchers have overturned the traditional view that oxygen derives from water splitting, instead finding that reactive oxygen species (ROS) produced at mineral-water interfaces are a key source of oxygen. This discovery has significant implications for understanding the evolution of Earth's atmosphere and the habitability of early life.
