You know it's true.  It's common sense.  Continue to exercise and you will have a better life. Muscle mass will decrease as you age unless you stop it but 12 weeks of training geared towards improving muscular power in older people were shown to be highly effective for improving their functional capacity and quality of life, according to studies carried out by the Biomechanics and Physiology of Movement research group at the Public University of Navarre.
In time for Valentine's Day, researchers have determined which champagne glass size will give drinkers the optimal experience. 
While anti-science politicians in Washington, D.C. block science solutions to harvesting more fish, a crucial piece of information about salmon isn't being considered; the numbers without a science solution only look good because of the massive influx of hatchery-raised fish that return to spawn in the wild. Only about ten percent of the fall-run Chinook salmon spawning in California's Mokelumne River are naturally produced wild salmon.
Recent research examined suicide rates north and south of the border between 1960 and 2008 and revealed the widening gap in suicide rates between Scotland and England and Wales is largely due to the number of young Scottish men taking their lives.

The suicide rate for both men and women was lower in Scotland than the rest of the United Kingdom until around 1968 when it overtook the other two but suicide rates among men continued to rise on both sides of the border until the early 1990s when rates in England and Wales began to fall. The gap between north and south widened markedly.

The deadliest mass extinction that we know of, 252 million years ago at the end of the Permian period,  took a long time to kill most of Earth's life, and it killed in stages. It wasn't superior to sudden extinctions just because it was gradual.

By the end of the Permian period, Earth was almost a lifeless planet. Around 90 percent of all living species disappeared then, in what scientists have called "The Great Dying." Chemical evidence buried in rocks formed during this major extinction can tell science part of what happened.
Bacteria can multiply rapidly, potentially doubling every 20 minutes in ideal conditions but this exponential growth phase is preceded by a period known as lag phase, where no increase in cell number is seen. Lag phase was first described in the 19th Century, and was assumed to be needed by bacteria to prepare to exploit new environmental conditions - they are basically Zombies. Beyond this, surprisingly little is known about lag phase, other than bacteria are metabolically active in this period. But exactly what are bacteria doing physiologically during that time?
