Iran used to be our enemy but lately, they’ve been acting more friendly. But the war against Iraq has them worried, and they’re getting technological assistance from China and North Korea in order to develop missiles and weapons of mass destruction. They may want to defend themselves from their old enemy Iraq?or they may think that after we get rid of Saddam, they’ll be next.

Undersecretary of State John Bolton says, “Although the current focus is on Iraq, and to a lesser extent on North Korea, Iran remains a very serious problem, one that we’re committed to addressing, and that we are trying to address by preventing the Iranian government from acquiring these capabilities in nuclear, biological and chemical weapons and long-range missiles.”

The demise of model rocketry may seem like a small price to pay for homeland security, but for those who love to build and fly them, it’s a major tragedy. But they can’t fly without solid rocket motors, and UPS has stopped shipping them due to the Safe Explosives Act, which is part of the new Homeland Security provisions. Rocketeers are pressing congress to change the law so they can continue flying their models. Find out how to contact your congressman so the rockets can continue to fly.

If we can’t prevent air pollution from happening, why not install air cleaners instead? Trees are natural air scrubbers, taking in the greenhouse gas carbon dioxide and giving off oxygen, so Klaus Lackner invented an artificial tree. It’s not very pretty, however. “It looks like a goal post with Venetian blinds,” he admits. But one synthetic tree can remove 90,000 tons of CO2 in a year?the emissions from 15,000 cars.

They can be planted anywhere. Every home could have one on the lawn to absorb the CO2 emitted by that family. Or large ones the size of a building could sit out in the open near highways or power plants. He thinks 250,000 synthetic trees worldwide will be enough to soak up the 22 billion tons of CO2 produced each year.

Global warming may have created a new type of cloud called noctilucent or “night shining” clouds (NLCs). They’re thin and wispy and have an electric blue glow. “Over the past few weeks we’ve been enjoying outstanding views of these clouds above the southern hemisphere,” says space station astronaut Don Pettit. “We routinely see them when we’re flying over Australia and the tip of South America.” He estimates they?re 50 to 62 miles above the Earth’s surface, “literally on the fringes of space.” You can see them from Earth as well, glowing in the night sky after sunset.
