But what is it? – Astronomers tell us that the mysterious substance called dark matter is the main substance in the universe?but we just can?t find it. It’s the same sort of thing that quantum physicists say about parallel universes or “brane worlds” (worlds that contain a different number of dimensions from ours). Astronomers can detect the presence of dark matter by the way gravity behaves around it. Now they have new evidence that it really exists.

A federal judge recently ruled that it is illegal for the government to bug people’s phones in the cause of Homeland Security. But what about all that email you send? LiveScience.com reports that your keyboard can easily be bugged so that someone can “read” your passwords and other sensitive data.

Computer expert Matthew Blaze says that this bugging device, which is far more powerful than a common Trojan orrootkit, is almost impossible to detect because it works by adding nearly imperceptible processing delays after a keystroke. According to LiveScience.com, these bugs have not actually been put into use yet, but since Livescience is a spin off of the NASA web site space.com, this may not be entirely accurate.

We’ve learned that bees may communicate through a quantum dance. But they also know something we don’t: the color of a flower indicates how warm the nectar inside it is. That doesn’t mean much to us, but it’s important to know if you’re a bee, because eating their food warm can mean the difference between life and death.

In LiveScience.com, Sara Goudarzi quotes Lars Chittka, writing in the journal Nature, as saying that, from a bee’s point of view, “if you need to warm up, you can produce your own heat, at the expense of some of your energy reserves?or you can consume a warm drink, and save on investing your own energy.”

UPDATE – One thing that has long puzzled researchers is the small number of people who are infected with the HIV virus but don’t come down with AIDS. UPDATE: New research breakthroughs may mean that soon, people with AIDS may be able to stave off the effects of the disease by taking regular doses of a protein that prevents deterioration of the immune system.

In Africa, around one in 300 cases of people with HIV do not go on to get AIDS. Canadian studies show that, in the West at least, these cases may be around 1% to 2% of all infected people.
