A device that mimics one of nature's key transport machines.
To help protect its genes, a cell is highly selective about what it allows to move in and out of its nucleus. Yet that choosiness is regulated by just a thin barrier, perforated with tiny transport machines called nuclear pore complexes: protein-coated holes surrounded by flimsy, unfolded protein strands.

Is It Possible For DNA To Have Telepathic Properties?
Scientists are reporting evidence that contrary to our current beliefs about what is possible, intact double-stranded DNA has the “amazing” ability to recognize similarities in other DNA strands from a distance. Somehow they are able to identify one another, and the tiny bits of genetic material tend to congregate with similar DNA.

Top 10 Scientific Breakthroughs of 2008
Scientists had plenty of reasons to celebrate in 2008. After decades of work, researchers made rat stem cells, built the first memristor, and watched a language evolve like an organism. But none of those accomplishments impressed us as much as the breakthroughs on this list. From stem cell therapy to finding ice on Mars.

Habitable Exoplanets Could be Common in Our Galaxy
By observing the remains of smashed up asteroids around dead stars, astronomers were able to deduce their chemical composition. They found that the dust of many chewed-up asteroids resembles the materials inside Earth and the other small, rocky inner planets of our solar system.

Inventor: Geo-Engineer a Worldwide Refrigerator Using Oceans
Bailing out the entire human race might turn out to be cheaper than bailing out Wall Street: Spray gigatons of seawater into the air, mainly in the Northern Hemisphere, and let Mother Nature do the rest, suggests inventor Ron Acer in a patent petition for “a colossal refrigeration system with a 100,000-fold performance multiplier.”

How Hunting is Driving Evolution in Reverse
When hunting is severe enough to outstrip other threats to survival, the unsought, middling individuals make out better than the stronger alpha animals, and the species changes. "Survival of the fittest" is still the rule, but the "fit" begin to look unlike what you might expect.

Scientists Discover True Love
Brain scans have proved that a small number of couples can respond with as much passion after 20 years as most people exhibit only in the first flush of love...researchers nicknamed the couples “swans” because they have similar mental “love maps” to animals that mate for life such as swans, voles and grey foxes.

Canada's forests now add to, not subtract from, climate woes
The country's 1.2 million square miles of trees -- dubbed the "lungs of the planet" by ecologists because they account for more than 7 percent of Earth's total forest lands -- could always be depended upon to suck in vast quantities of carbon dioxide, cleansing the world of much of the harmful heat-trapping gas. Not anymore.
