Hydrogen is becoming an increasingly popular choice as we shift towards cleaner energy. It can be burned like traditional fuels, producing only water as a byproduct, and can generate electricity when used in fuel cells. However, as hydrogen production, use, and transportation increase, so do safety concerns. Hydrogen is highly flammable at concentrations as low as 4% and is odorless and colorless, making leaks challenging to detect. To address these concerns, researchers led by Professor Yutaka Majima from Institute of Science Tokyo (Science Tokyo) have developed a sensor that detects hydrogen at ultra-low concentrations ...

The differences in US health and life expectancy based on where an individual lives, the economic conditions in that location, and their racial and ethnic identity have increased over the last two decades, leading to substantial health disparities that divide the USA into ten mutually exclusive populations, which the study authors term “The ten Americas”. The life expectancy gap—an important indicator of a population’s health— across these ten Americas increased from 12·6 years in 2000 to 20·4 years in 2021, exacerbated by the COVID-19 pandemic. Between 2000 and 2010 life expectancy increased in nine out of ten Americas, but between 2010 ...

A massive collision of galaxies sparked by one travelling at a scarcely-believable 2 million mph (3.2 million km/h) has been seen in unprecedented detail by one of Earth's most powerful telescopes. The dramatic impact was observed in Stephan's Quintet, a nearby galaxy group made up of five galaxies first sighted almost 150 years ago. It sparked an immensely powerful shock akin to a "sonic boom from a jet fighter" – the likes of which are among the most striking phenomena in the Universe. Stephan's Quintet represents "a galactic crossroad where past collisions between galaxies ...

The intestine maintains a delicate balance in the body, absorbing nutrients and water while maintaining a healthy relationship with the gut microbiome, but this equilibrium is disrupted in parts of the intestine in conditions such as celiac disease, ulcerative colitis, and Crohn’s disease. Scientists don’t fully understand how different regions of the organ resist or adapt to changes in the environment and how that is disrupted in disease. Now, researchers at the Broad Institute of MIT and Harvard and Massachusetts General Hospital have analyzed the entire mouse intestine, mapping gene expression and cell states and location in the healthy gut and in response to ...

A recent study in JAMA Network Open sheds light on how school attendance influences the spread of infectious diseases, using COVID-19 as a case study. Researchers analyzed the natural age cutoff for kindergarten eligibility in California to compare COVID-19 rates between children old enough to start school and those who were not. This approach, called regression discontinuity, offers a way to rapidly understand the role of schools in disease transmission and evaluate the effectiveness of within-school prevention measures without requiring additional data collection or school closures. The study's findings underscore the complexity of school-based transmission ...
