extinction

Recent research suggests that volcanic eruptions, causing global cooling, significantly contributed to the dinosaurs’ extinction, challenging the long-held belief that a meteorite was the sole cause. McGill researchers challenge the current understanding of dinosaur extinction by unearthing a link between volcanic eruptions and climate change. What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have…

A new paper published in Science says that as glacier ice melts, new land and rivers are being revealed in the ice-covered transboundary region shared by northern B.C., Alaska, and the Yukon. The peer-reviewed paper was a collaboration among researchers from Simon Fraser University, the Gitanyow Hereditary Chiefs' Office, the University of Montana Flathead Lake Biological Station, and Taku River Tlingit First Nation.Researchers say that for Pacific salmon, these emerging territories may present an opportunity to offset…

A study in Nature Geosciences reveals that oceanic anoxia significantly contributed to marine extinctions during the Triassic–Jurassic period, with current levels of deoxygenation mirroring those of the past. This discovery highlights the sensitivity of marine ecosystems to local and global environmental changes. Scientists have discovered a pivotal role of oceanic anoxia in the Triassic–Jurassic mass extinction, indicating that even localized deoxygenation can lead to widespread ecosystem collapse. This research…

Dartmouth scientists used an innovative computer model to suggest that volcanic activity, rather than an asteroid impact, was the primary cause of the mass extinction that ended the age of the dinosaurs. This groundbreaking approach opens new avenues for investigating other geological events.Free-thinking computers reverse-engineered the fossil record to identify the causes of a cataclysm.To address the long-standing debate about whether a massive asteroid impact or volcanic activity caused the extinction of dinosaurs and…

Seen through a lens of ongoing technological and medical progress it's easy to feel optimistic about humanity's future prosperity. Scratch a little deeper, it soon becomes clear that our success as a species is anything but guaranteed.New research led by a team from the University of Stockholm in Sweden outlines 14 different "evolutionary traps" that our global population could potentially be ensnared by, ultimately leading to our demise.According to the team behind the study, part of the problem is that we've been doing…

New research on cycads, ancient plants from the Mesozoic Era, reveals that their survival into the modern era can be attributed to a symbiotic relationship with nitrogen-fixing bacteria. This study provides insights into the ecological evolution of cycads and their adaptation to past climate changes.Cycads, ancient plants once prevalent during the Mesozoic Era, have mostly gone extinct, with a few species surviving in tropical and subtropical areas. Researchers have discovered that these surviving cycads relied on…

Despite incredible advances in modern genomic research, science is nowhere near being able to clone long-extinct animals like the fictional ones in Jurassic Park. Even relatively recent extinctions remain enormously difficult to overcome. An innovative branch of research that joins robotics with paleontology, however, does let scientists bring back long-gone creatures in a different way: not with cells and DNA but with engineering skill and batteries.An interdisciplinary team has built a robotic mimic of a bizarre and…

‘The extinction of dinosaurs’ is one of the greatest mysteries in Earth's history which is again in focus with claims that a massive cloud of dust may have been a key factor in the extinction of…
