The Earth is surrounded by a magnetic shield that protects us from solar radiation. The problem is, it can leak. Researcher Harald Frey says, "We’ve discovered that our magnetic shield is drafty, like a house with a window stuck open during a storm. The house deflects most of the storm, but the couch is ruined." Can we safely colonize Mars, which does not have a shield to protect us from the sun? Only if we’re careful.

Physicist Michio Kaku says he knows of nothing that makes time travel impossible and “In the laws of physics, if it’s not forbidden, it’s mandatory. This is pretty much proven every time.” And an amateur explorer says he’s discovered a portal where time is altered.
In msnbc.com, Alan Boyle quotes Kaku as saying, “Over the last 10 years there’s been a sea change. Ten years ago, you would be considered a lunatic if you proposed that time travel was possible?Now, the burden of proof has shifted to the cynics, who have to prove that it?s not possible.”

Just when the controversial new Medicare drug bill has been passed, a new report has come out showing that half the time, prescription drugs don’t work. And a couple of illegal drugs can cause changes in DNA that can be passed down to future generations.

Connor writes, “It is an open secret within the drugs industry that most of its products are ineffective in most patients but this is the first time that such a senior drugs boss has gone public.”

It’s been discovered that the force of sunlight on an asteroid can change its orbit, which is one reason why asteroids change direction and head for Earth. What we don’t know is this: Will the increased solar activity on the sun right now have an increased effect on asteroids?
Eugenie Samuel Reich writes in New Scientist that astronomers have detected the influence of sunlight on asteroids for the first time, since it’s very subtle. However, it’s enough to coax them out of the Solar System’s asteroid belt and into an orbit that can impact Earth.
