I can't seem to manage to keep my iPod in my bag for a day without creating an awful tangle of headphones, but my body's cells can work with two meters of stringy DNA into a tiny nucleus without making a knot. The secret is a structure called a fractal globule, according to a research paper to be published tomorrow in the journal Science.

Researchers have shown for the first time today that a vaccine can help reduce drug abuse. There's currently no FDA-approved treatment to get people off of cocaine (or crack), so this could really help out the 2.5 million Americans dependent on cocaine.

Thirty-eight percent of drug abusers who were given the vaccine produced anti-cocaine antibodies. Over the course of seven weeks, these subjects were 45 percent likely to have a cocaine-free pee test, as opposed to 35 percent for those who got placebo vaccine instead.

Snort your way to perfect health? Just last week, we heard that snorting stem cells might be the best way to get them into your noggin. And this week, scientists have declared that a nasal spray can help your memory.

This morning, scientists revealed an analysis of a female skeleton that seems to be the best example of early hominids around, about a million years older than the famous Lucy specimen that has been a prime example of early humanoids for about 40 years. New species Ardipithecus ramidus, which scientists nicknamed "Ardi," lived in the woodlands of present-day Ethiopia and had a blend of human and chimplike features.

Researchers from Georgia Tech have devised methods to take real-time, real-world information and layer it onto Google Earth, adding dynamic information to the previously sterile Googlescape.

They use live video feeds (sometimes from many angles) to find the position and motion of various objects, which they then combine with behavioral simulations to produce real-time animations for Google Earth or Microsoft Virtual Earth.

Although science news is often muddied by qualifiers, the news today is clear. After decades of believing that the moon was a dry, dusty wasteland, we now know that there is water on the moon's surface. This discovery means that colonizing the moon could be a bit easier, since water could be used to produce oxygen and fuel, not to mention a delicious glass of refreshment.

Small acts of eco-kindness can make people more likely to cheat and steal.

In a recent paper by a pair of researchers at the University of Toronto, entitled "Do Green Products Make Us Better People?" the answer seems to be, eh, not completely. Although you may have done Mother Earth a favor, your unconscious might sway you to be less ethical with your fellow man.

No matter how intelligent a robot might be, it’s nice knowing you can pull its plug to halt the anti-human insurrection. Whoops, not anymore. A new cohort of ’bots that make energy by gobbling organic matter could be the beginning of truly autonomous machines.

Scientists working on behalf of NASA have successfully levitated a mouse using a strong magnetic field. I pay taxes so that stuff like this can happen. I don't hate animals. It's for understanding microgravity better, ok?

First Solar just signed an agreement with China to build the biggest solar power plant yet, according to a statement released today by the company. The 2-gigawatt plant in the Mongolian desert will generate enough electricity to power three million homes.

That's a heck of a lot of cadmium telluride, the semiconductor they use for their thin film cells.

A long-hypothesized particle, stuff of tantalizing detection attempts and thrilling sci-fi novels, may have finally been sighted.

While the LHC's in the shop for repairs from its massive breakdown last September, an older particle accelerator might beat them to finding the Higgs boson, the fundamental particle thought to give matter mass.

At a conference last week, Tevatron physicists threw down the gauntlet, vowing that by 2011, the Tevatron accelerator (located at Fermi National Accelerator Lab outside Chicago) will be able to definitively prove or disprove the existence of the Higgs boson.
