A new study comparing wild and zoo-housed Sumatran orangutans reveals that life in a zoo significantly alters how orangutans interact with their environment. Researchers analyzed over 12,000 instances of daily exploratory object manipulation (EOM) -- the active manipulation and visual inspection of objects associated with learning and problem-solving -- across...
Seasonal changes affect alcohol tolerance and your waistline
Researchers have found that drug effectiveness, alcohol tolerance, and carbohydrate metabolism change with the seasons. Their findings are based on a comprehensive seasonal gene expression map, which investigated over 54,000 genes in 80 tissues in monkeys across one year. The study has implications for drug prescription and precision medicine.
Geobiology: Iron, sulfur, heat — and first life
The very first cells obtained their energy from geochemical reactions. Researchers have now managed to recreate this ancient metabolic process in their laboratory.
Restoring oil wells back to nature with moss
In what could represent a milestone in ecological restoration, researchers have implemented a method capable of restoring peatlands at tens of thousands of oil and gas exploration sites in Western Canada. The project involves lowering the surface of these decommissioned sites, known as well pads, and transplanting native moss onto...
One of Earth’s ancient volcanic mysteries solved
A new study traces a 120-million-year-old 'super-eruption' to its source, offering new insights into Earth's complex geological history.
Landmark experiment sheds new light on the origins of consciousness
An experiment seven years in the making has uncovered new insights into the nature of consciousness and challenges two prominent, competing scientific theories: Integrated Information Theory (IIT) and Global Neuronal Workspace Theory (GNWT). The findings mark a pivotal moment in the goal to understand the elusive origins consciousness.
Giant croclike carnivore fossils found in the Caribbean
Imagine a crocodile built like a greyhound -- that's a sebecid. Standing tall, with some species reaching 20 feet in length, they dominated South American landscapes after the extinction of dinosaurs until about 11 million years ago. Or at least, that's what paleontologists thought. A new study shows the Caribbean...
Global study links consumption of ultraprocessed foods to preventable premature deaths
A study analyzing data from nationally representative dietary surveys and mortality data from eight countries (Australia, Brazil, Canada, Chile, Colombia, Mexico, United Kingdom, and United States) shows that premature deaths attributable to consumption of ultraprocessed foods (UPFs) increase significantly according to their share in individuals' total energy intake. The new...
Rainfall triggers extreme humid heat in tropics and subtropics
Scientists believe they have found a way to improve warning systems for vulnerable communities threatened by humid heatwaves, which are on the rise due to climate change and can be damaging and even fatal to human health. The study analysed how patterns of recent rainfall can interact with dry or...
Heart disease deaths worldwide linked to chemical widely used in plastics
Daily exposure to certain chemicals used to make plastic household items could be linked to more than 356,000 global deaths from heart disease in 2018 alone, a new analysis of population surveys shows. While the chemicals, called phthalates, are in widespread use globally, the Middle East, South Asia, East Asia,...
