The amount of exercise may be more important than intensity to improve cardiovascular health, according to a new analysis of the first randomized clinical trial evaluating the effects of exercise amount and intensity in sedentary overweight men and women. This finding of the value of moderate exercise should be encouraging news for those who mistakenly believe only intense exercise can improve health, said the researchers who conducted the trial.
The trial, led by researchers at Duke University Medical Center, found that a moderate exercise regimen, such as 12 miles of brisk walking each week, can provide significant improvements in fitness levels while reducing the risks of developing cardiovascular disease. Furthermore, the researchers found that any additional increase in amount or intensity can yield even more health benefits.
The results of the analysis were published in the October, 2005, issue of the journal Chest.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
