FORTUNE -- AT&T executives looking to convince regulators to approve Ma Bell's merger with T-Mobile argue that the cell phone market is plenty competitive. Just look at the growth of new competitors such as Cox Communications, a cable company that built and runs a brand new cellular network, they say.

Despite a 500-fold increase in radiation exposure from cell-phones since 1990, brain cancer rates have fallen.
FORTUNE -- During the 1980s, just as Americans began pumping low-frequency radiation through their skulls with cell phones, brain cancer rates in the U.S. slowly increased. At the beginning of the decade, doctors delivered the devastating diagnosis of brain cancer to 63 out of every 1 million Americans every year; by 1990 that number had risen MOREScott Woolley - Jun 7, 2011 11:22 AM ET
With America asleep and saturation coverage available on old-fashioned TV, online viewership for the wedding was meager.
So much for today's royal wedding straining the Internet to the breaking point. Even at the ceremony's height, Internet users around the world only downloaded 5.4 million pages per minute. That makes it only the sixth most popular online news event in history -- right behind the U.S. match with Algeria in the World MOREScott Woolley - Apr 28, 2011 9:47 PM ET
The world's dominant Internet backbone just got a lot more dominant. Should we worry?
Level 3 already runs the single most important part of the Internet. Of the 36,878 autonomous networks that collectively make up the global Internet, Level 3 (LVLT) is by far the largest and most interconnected. Buying Global Crossing (GLBC), which by most measures is now the global Internet's third largest part, in a $3 billion deal will only cement that position.

China will grow on a scale the world has never seen before. Can that growth be green?
The environmental consequences of China's economic growth are both well-known and horrifying: more cars, more coal and more toxic crud fouling its streams and rivers. Less appreciated are the reasons for hope.

Kleiner Perkins' Green guru believes on a household level, green power needs to recharge advanced batteries rather than plug right into the fuse-box.
FORTUNE -- Having helped both create the Java programming language and co-found Sun Microsystems, Bill Joy is best known as a technologist and entrepreneur. He hopes to add environmentalist to that list.

New companies say pulling carbon dioxide straight from the air could solve global warming and provide an infinite source of gasoline. Really?
FORTUNE -- What if scientists could transform coal-fired power plants from giant carbon dioxide emitters into giant carbon sinks? Some say that they can, and will. Graciela Chichilnisky, a founder of Global Thermostat, admits it's hard to believe: "The more energy the less the emissions—it's mind boggling."

Could a friendly fungus eventually eliminate styrofoam packaging? Don't laugh, it just might.
FORTUNE -- If your job was to ship 250 pounds and $25,000 dollars worth of computer servers, you'd no doubt pack them in a box using only the safest materials. And yet when Dell (DELL) ships four of its PowerEdge R710 servers it will soon offer a new packaging made of...mushrooms.

FORTUNE -- Making chemicals takes energy -- a lot of it -- so the mere fact that Dow Chemical (DOW) can save a lot of money by improving their energy efficiency is not what's surprising. It's just how much energy and cash they've MOREScott Woolley - Apr 5, 2011 11:25 AM ET
