The Barrow-in-Furness accent is very different from the rest of Lancashire and Cumbria because of an intense mixing and rapid population change in the late 1800s, says new research by Lancaster University, which used the voices of Victorian speakers to inform the study.
Around 540 million years ago, Earth's biosphere underwent a pivotal transformation, shifting from a microbe-dominated world to one teeming with animal life, as nearly all major animal phyla appeared abruptly in the fossil record over a very short geological time interval. This
When it comes to global warming and climate change, we often hear news stories about tipping points where Earth's systems shift into a new and dangerous state. One such may have been reached in the year 2000 that caused tropical weather cycles to have a greater effect on autumn
In a study conducted by Dr. Mahdi Alirezazadeh and Dr. Hanan Bahranipoor, published in Archaeological Research in Asia, two exceptionally well-preserved fetal burials from Chaparabad, Iran, dating to the mid-5th millennium BC, were analyzed including burial L522.1, one of the
Dangerous concentrations of algae such as "red tides" have been consistently emerging in locations around the world. A region in Southern Australia is experiencing a nine-month toxic algae bloom that spans thousands of miles and has caused thousands of deaths across marine
Ditches and canals are the underdog of the freshwater world. These human-made waterways are often forgotten, devalued, and perceived negatively—think "dull as ditchwater." But these unsung heroes have a hidden potential for climate change mitigation, if they're managed correctly.
A new study finds that Canada could remove at least five times its annual carbon emissions with strategic planting of more than six million trees along the northern edge of the boreal forest. The paper, "Substantial carbon removal capacity of Taiga reforestation and
In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner crystal state remains sensitive to various experimental
When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like mice, this replay still occurs — but the signals are jumbled and poorly coordinated. As a result, memory-supporting brain cells lose their stability, and
Middle age is becoming a tougher chapter for many Americans, especially those born in the 1960s and early 1970s. Compared with earlier generations, they report more loneliness and depression, along with weaker physical strength and declining memory. These troubling trends stand
Travel misery was set to continue Sunday as a powerful snowstorm blasted southern US states, bringing subzero temperatures to regions not accustomed to the deadly winter conditions.
An international team has discovered the earliest known hand-held wooden tools used by humans. A study jointly led by Professor Katerina Harvati from the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen and Dr. Annemieke Milks at the
The life of one of the most remote grizzly bear populations in the world is being documented by the animals themselves, with collar cameras that provide a rare glimpse of how they survive on Alaska's rugged and desolate North Slope.
NASA began a two-day practice countdown Saturday leading up to the fueling of its new moon rocket, a crucial test that will determine when four astronauts blast off on a lunar flyby.
When I see a great white shark, I am in awe of the enigmatic, powerful apex predator. My life has been dedicated to trying to know everything about sharks and immersing myself in their world. Most people when they see "shark attack" automatically think of white sharks
The National Reconnaissance Office has now declassified a satellite program used to spy on America’s adversaries
Old Indian poems and folk songs are revealing a surprising truth about the land. Scientists found that descriptions of thorny trees and open grasslands in texts written as far back as the 1200s closely match today’s savannas in western India. This suggests these landscapes are
Traditional processes used to discover new materials are complex, time-consuming, and costly, often requiring years of sustained effort. Recent advances in large language models (LLMs) have demonstrated powerful capabilities in information processing, offering new opportunities
Scientists warn that rapid advances in AI and neurotechnology are outpacing our understanding of consciousness, creating serious ethical risks. New research argues that developing scientific tests for awareness could transform medicine, animal welfare, law, and AI development.
Dinosaur footprints have always been mysterious, but a new AI app is cracking their secrets. DinoTracker analyzes photos of fossil tracks and predicts which dinosaur made them, with accuracy rivaling human experts. Along the way, it uncovered footprints that look strikingly
