Just as humans exhibit right- or left-handedness, moths also have a preferred side on which they place their proboscis when inspecting a flower for nectar. This observation was made by Konstanz-based biologists in their latest study. The researchers see this as an example of
Introducing a 2% minimum annual tax on households with more than £100 million in wealth could raise around £10 billion in 2026, while affecting fewer than 1,000 households in the UK, suggests a report by academics at King's College London, the Paris School of Economics and the
Scientists documented humpback whales hunting together at the seafloor, coordinating their arrival to scoop up sand lances.
While humans are inherently social beings, psychology studies suggest that their social skills are gradually fine-tuned over time and with experience. Understanding when different social skills emerge and how they typically develop could help devise new strategies that
"It's not personal, it's strictly business." This line, which echoes throughout Francis Ford Coppola's 1972 gangster film "The Godfather," epitomizes the classic view of management: Doing business is, above all, about making money, even if it means sacrificing all the personal
Ancient fern savannahs may have transformed parts of Europe into a wildfire-prone inferno during the end-Triassic mass extinction. New fossil evidence suggests the ferns repeatedly regrew after fires, creating fresh fuel that helped prolong the devastation.
Before a hydra can regrow a head or foot, its cells appear to rebuild the internal map that tells them where they are and what they should become next, FMI researchers report. The work suggests that cells need to interpret not only where they are in the body, but also what
Microbes in the gut, lungs and biofilms do not simply exist as perfectly mixed populations; instead, they grow in layered and clustered three-dimensional (3D) arrangements. This spatial organization shapes how nutrients and chemical signals move between neighboring cells and
Colorectal cancer is now the leading cause of cancer death among people under 50, and cases in younger adults continue to rise. Warning signs can include persistent bowel changes, recurring rectal bleeding, dark or narrow stools, unexplained weight loss, and fatigue. These
About 90% of the Aral Sea has dried up. The exposed sediments have already released enormous amounts of carbon dioxide (748 megatons) since 1960. However, through restoration, the lake could once again become a carbon sink. This is shown by a study by the Centre for Advanced
Many modern technologies, from optical communications and artificial intelligence (AI) hardware to advanced sensors and medical imaging, depend on photonic and semiconductor devices that precisely control the interaction between light and electrons. Designing these devices,
