NEW DELHI: People with no high BP, diabetes or smoking habit lived nearly 13 years longer without dementia than those with all three risk factors, a long-term US study has found. Those without any of the three lived an average 30 years without dementia from age 55, compared with 17.5 years among those with all…
The four-hectare barley field was abandoned in 1961 after researchers harvested its final crop, allowing nature to take over without further human intervention. In 1961, researchers at Monks Wood in Cambridgeshire harvested a final crop of barley from a four-hectare agricultural plot known as Stocking Close, ploughed the soil and walked away. They did not…
An ecosystem collapse in Montana remains a lasting lesson in how well-intentioned wildlife management can have devastating consequences. When state wildlife officials introduced a non-native, tiny crustacean into nearby lakes in 1968, the goal seemed simple. They believed stocking the opossum shrimp, Mysis diluviana, would provide an extra food source and help increase populations of…
The gopher tortoise is a land-dwelling reptile native to the southeastern United States that digs deep burrows used by hundreds of other animals. More than two decades after two Mississippi landowners began restoring their land to help an endangered tortoise, their work has now created a new home for one of North America’s rarest amphibians….
For millions of years, birds have been changing in ways that are difficult to see from the present day. A skeleton in a museum may look like a fixed record of one species, but taken together, thousands of specimens can reveal how bodies changed across vast stretches of time. That is what a team at…
Seth NabatPhoto: Society for Science Every year, nearly 1,900 of the nation’s most promising high school seniors submit original research to the Regeneron Science Talent Search (Regeneron STS), the oldest and most prestigious science and mathematics competition in the United States. According to the Society for Science, which runs the competition, the Regeneron STS recognises…
Joel Sartore started the project with a simple but powerful idea: to photograph animals one species at a time, creating a visual record before they are gone. (Image: Instagram/joelsartore) In a world where species can disappear before most people even know they exist, photographer Joel Sartore has spent two decades making sure wildlife is seen….
Jane Goodall spent decades studying chimpanzees in the wild before becoming one of the world’s most recognisable voices for wildlife conservation and environmental protection. Her work changed how scientists understood chimpanzee behaviour and helped demonstrate the importance of protecting animals and their habitats. One of her most widely shared messages is simple: “Every individual matters….
In the sun-drenched hills of Andalusia, Spain, an unlikely team of firefighters is making headlines. They don’t carry hoses, wear helmets, or race to blazes in red trucks. Instead, they have four legs, long ears and a simple mission: eat grass. Meet the “firefighting donkeys” of Doñana National Park, a group of 18 rescued animals…
Rhinocyllus conicus (Image Credit: Canva) A biological control programme launched in the United States more than five decades ago has become a cautionary example of how attempts to manage invasive species can produce unexpected ecological consequences. According to a USDA Forest Service assessment of invasive species in the Southwest, the thistle seedhead weevil (Rhinocyllus conicus)…
