Newswise – ?But climbing that mountain can be a problem. Researchers have learned that mountain dwellers live longer than people in lowland areas. But beware: Every year, about 1,000 tourists climb Mount McKinley, but many of them have to scurry back down again due to diarrhea, and doctors can’t figure out what’s causing this.

The fact that people living in high elevations live longer is based on a 15-year study of the cardiovascular health and death rates of over a thousand inhabitants of three villages in Greece over a period. While Greeks do not have especially good health habits by our standards–many of them both drink and smoke–Greece has one of the lowest rates of heart disease in the world.

Hybrid automobiles can be made even more environmentally friendly by the addition of solar cells. Environmentalist Steven Letendre says, “If the 200 million cars in the United States had 500 watts of solar cells integrated into their body panels, it would represent roughly one-seventh of the total installed generating capacity in the United States.” While it’s doubtful that people will embed solar cells in the bodies of their older cars, new hybrid automobiles could be manufactured this way.

While some scientists see incredible changes coming in the future, others despair to think that ancient prejudices could still be causing tragedies like 911 and the recent terrorist attacks on London. English Astronomer Royal Martin Rees, who has been interviewed on Dreamland, says that science has changed the world faster in the 21st century so far than it has ever been changed before, and that the biggest questions we still need to answer are what makes us human and how did we came to exist.

Pesticide levels that were previously thought to be safe for bees may actually be harmful to them. Adult bumble bees exposed to the pesticide spinosad have an impaired ability to forage for food. Spinosad is a natural pesticide derived from the bacteria Actinomycetes. It’s used in over 30 countries, including North America, Canada and the UK, to combat common crop pests such as caterpillars and thrips. Bees are important pollinators of crops. In developed countries, about a third of human food relies on their pollination. Less dramatic effects on honey bees could be going unnoticed, and other species could also be affected.
