Ultimate limit of human endurance found

Ultimate limit of human endurance found

Science
The ultimate limit of human endurance has been worked out by scientists analysing a 3,000 mile run, the Tour de France and other elite events.They showed the cap was 2.5 times the body's resting metabolic rate, or 4,000 calories a day for an average person.Anything higher than that was not sustainable in the long term.The research, by Duke University, also showed pregnant women were endurance specialists, living at nearly the limit of what the human body can cope with.The study started with the Race Across the USA in which athletes ran 3,080 miles from California to Washington DC in 140 days.Competitors were running six marathons a week for months, and scientists were investigating the effect on their bodies. ...

New research shows human cells mimic computer chips

Science
May 24 (UPI) -- Living cells are wired like computer chips, using direct signals to instruct them how to function, but they can also change behavior rapidly -- something chips can't do, new research by the University of Edinburgh suggests. The cell-wide web discovery deepens scientists' understanding of how instructions spread through the body. The new research found information is carried across a web of guide wires that transmit signals across tiny, nanoscale distances. The movement of charged molecules across the tiny distances that transmit information, similar to how a computer microprocessor works. "We found that cell function is coordinated by a network of nanotubes, similar to the carbon nanotubes you find in a computer microprocessor," said Professor Mark Evans, of the Universit...
Human impact on drought dates back 100 years, NASA study says

Human impact on drought dates back 100 years, NASA study says

Science
May 2 (UPI) -- The human impact on today's environment may have been happening a lot earlier than some people think. Humans have been creating atmospheric particles and greenhouse gases that contributed to worldwide droughts since the early 20th century, according to a study published Wednesday in Nature. The researchers measured soil moisture using a Palmer Drought Severity Index and drought atlas calculated by tree rings. The atlases could estimate when and where droughts occurred. "If you look at the fingerprint, you can say, 'Is it getting dry in the areas it should be getting drier? Is it getting wetter in the areas it should be getting wetter?'" said Kate Marvel, an associate research scientist at Columbia University and study lead author, in a news release. "It's climate detective...
Nature loss: Major report to highlight ‘natural and human emergency’

Nature loss: Major report to highlight ‘natural and human emergency’

Science
Scientists and government officials meet this week in Paris to finalise a key assessment on humanity's relationship with nature. The Intergovernmental Panel for Biodiversity and Ecosystem Services, or IPBES, will issue the first report of this type since 2005.It will detail the past losses and future prospects for nature and humans. One author says the report will highlight the "social and ecological emergency" the world is now facing.From Monday some of the world's leading researchers in the field of biodiversity will meet in the French capital to work through the details of their report with representatives from 132 governments. Their conclusions, known as a Summary for Policymakers, will then be published on 6 May. "I would say that this is the most co...

Reports: Human remains found at former Mouseketeer Dennis Day’s home

Entertainment
April 7 (UPI) -- Human remains have been discovered at the Phoenix, Ore., home of 1950s child star Dennis Day in the original Mickey Mouse Club show. The Oregon State Police said the body has not been identified and the investigation is ongoing. The Medford Mail Tribune reported the house belonged to Day, 76. Day appeared in two seasons of the show from 1955-57, joining actress Annette Funicello. He was one of 10 club members retained for the second season of the show created by Walt Disney, according to originalmmc.com. KDRV-TV said Day shares the home with his husband, Ernest "Ernie" Caswell. Caswell, who suffers from memory loss, reported Day missing in July, Oregon Live said. Caswell reportedly was in the hospital at the time. Let's block ads! (Why?) Entertai...
