A new study finds that swapping car travel for walking, cycling, and e-biking just one day a week can save up to a quarter of personal CO2 emissions from transport. Active transport reduces carbon footprints in cities, even in those with high walking and cycling rates.
A study of almost 26 million articles found citation rates increased for the top 1%, with Australasian and Western European universities gaining ground on US dominance. Global citation inequality rose over two decades.
Businesses are increasingly required to assess their vulnerability to climate change, but complex climate models pose a challenge for risk assessment and decision-making. A paradigm shift is needed to elevate climate modeling to operational weather forecasting level, providing tangible value to businesses.
A nationwide study aims to better understand the intersection of COVID-19 and cancer, examining long-term outcomes and treatment protocols. The research hopes to identify key factors that make certain patients more prone to severe COVID-19 infections.
A Korean research team developed a wearable sensor that can detect illegal drugs in sweat using nanomaterials technology, enabling fast and highly sensitive drug detection. The technology overcomes traditional methods' limitations and has the potential to address social problems related to drug distribution and abuse.
Researchers discovered that amphipods can close their claws in under 0.01% of a second, generating high-energy water jets and audible pops. The tiny creatures' fast movements defy physics laws, with potential applications for engineers and designers.
A study of over 100,000 patients found a significant drop in asthma attack rates during the first Covid-19 lockdown, with milder attacks being reduced, but potential biases due to hospitalization data. The results suggest lower air pollution and fewer cold and flu infections may have played a role in the observed decrease.
Vaccines against diseases like influenza and whooping cough have shown to be lifesaving when administered during pregnancy. Pregnant women are at increased risk of preterm birth or pregnancy loss if they develop severe COVID-19, highlighting the need for guidance on vaccine administration.
The global COVID19 pandemic may be an opportunity to rethink sustainable tourism's impact on Mediterranean beaches. Researchers found that 80% of marine litter comes from tourists' activities, generating huge amounts of microplastics.
A significant link between placental gene-expression loci and neonatal brain volume was found, with stronger correlations in males than females. Early life complications may exacerbate the risk of neurodevelopmental illness in individuals with schizophrenia-associated genetic markers.
