A new project collects more than 55,000 measurements of housing floor area across thousands of years of human history around the globe.

Deep sea mining operations are expected to increase the negative impact on environmental indicators by up to 13 per cent, a change categorized as having “great” significance, relative to the “without” DSM scenario, the study published in PLOS One said, notably through increased coastal vulnerability, pollution, and biodiversity loss.

About The Study: In this cross-sectional study of children ages 9 to 10, moderately preterm birth was associated with long-term cognitive problems independent of socioeconomic status, genetics, and other risk factors. These findings underscore the need for continued follow-up of all preterm children, with particular focus on those born before 34 weeks’ gestational age, because they may face greater developmental challenges over time.

McGill University researchers have developed an AI-powered method to verify the origin of honey, ensuring that what’s on the label matches what’s in the jar. The breakthrough offers a potential solution to a long-standing problem.

“Honey is one of the most fraud-prone commodities in global trade. It often involves mislabelling where it was produced or the types of flowers that bees collected nectar from,” said lead author Stéphane Bayen, Associate Professor and Chair of McGill’s Department of Food Science and Agricultural Chemistry.

In many careers, a person must learn foundational skills before advancing deeper into their profession. A recent paper in Nature Human Behavior mapped the dependency relationships between workplace skills, identifying a nested structure in many professions, where advanced skills depend on prior mastery of broader skills. This nestedness, they found, has significant implications for wage inequality and career mobility in increasingly complex labor markets.

A new study led by Professor Sayaka Nakamura from Sophia University in Japan and Professor Shiko Maruyama from Jinan University in China published in the journal Health Economics reveals the significant positive impact of the Japanese school lunch program on the weight of early teenagers. The research, titled "Wholesome Lunch to the Whole Classroom: Short- and Longer-Term Effects on Early Teenagers’ Weight," found that the program effectively reduces Body Mass Index (BMI), Percent Overweight (POW), and obesity rates, particularly among students from lower socioeconomic backgrounds.
