North meets south? Glaciers move together in far-flung regions
Results of a new study add evidence that climate swings in the northern hemisphere over the past 12,000 years have been tightly linked to changes in the tropics.
The findings, published this week in the journal Science, suggest that a prolonged cold spell that caused glaciers in Europe and North America to creep forward several hundred years ago may have affected climate patterns as far south as Peru, causing tropical glaciers there to expand, too.

Invasive species on the march: variable rates of spread set current limits to predictability
Whether for introduced muskrats in Europe or oak trees in the United Kingdom, zebra mussels in United States lakes or agricultural pests around the world, scientists have tried to find new ways of controlling invasive species by learning how these animals and plants take over in new environs.

The Arctic offers more evidence of human influences on climate change
A new study indicates that Arctic temperatures suddenly increased during the last 50 years of the period from 1 AD to the year 2000. Because this warming occurred abruptly during the 20th century while atmospheric greenhouse gases were accumulating, these findings provide additional evidence that humans are influencing climate.

Dead ahead: Similar early warning signals of change in climate
What do abrupt changes in ocean circulation and Earth's climate, shifts in wildlife populations and ecosystems, the global finance market and its system-wide crashes, and asthma attacks and epileptic seizures have in common?
According to a paper published this week in the journal Nature, all share generic early warning signals that indicate a critical threshold of change dead ahead.

Removing the barriers of autism
Autism can build a wall of poor communication between those struggling with the condition and their families. While a personal computer can help bridge the divide, the distraction and complexity of a keyboard can be an insurmountable obstacle.

Hurricane seasons are more active
For many Americans who live on the Atlantic coast, Andrew, Ivan and Katrina are more than just names -- they are reminders of the devastating impact of cyclonic activity in the region during hurricane season. If it seems like hurricane seasons have been more active in recent years, you're on to something. According to a paper published in the Aug. 13 issue of Nature, the frequency and strength of these powerful storms has grown in recent decades.

Uncovering the secrets of ulcer-causing bacteria
A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels. They showed that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host.
