New map aims to help battle for Arctic territories
August 6, 2008 08:43 AM - Reuters

British researchers unveiled on Wednesday what they billed as the "first ever" Arctic map to show key disputed territories in the resource-rich region. The map -- which highlights Arctic areas where boundaries are already agreed, as well as areas where claims have been made and where disputes could break out -- is designed to help world powers as they battle over rights to the remote but potentially lucrative area. "The map is the most precise depiction yet of the limits and the future dividing lines that could be drawn across the Arctic region," said Martin Pratt, director of research at the Durham University's International Boundaries Research Unit (IBRU).

Scientists Use Naval Exercises to Learn More About How Marine Mammals React to Sonar
August 6, 2008 08:24 AM - NOAA

NOAA’s Fisheries Service, in partnership with top international scientists and the U.S. Navy, has just completed a pioneering research effort in Hawaii to measure the biology and behavior of some of the most poorly understood whales on Earth. During the study, for the first time, scientists attached listening and movement sensors on marine mammals around realistic military operations.

Software predicts where El Niño will strike next
August 5, 2008 12:24 PM - New Scientist Tech

El Niño events periodically wreak havoc on the world's weather, increasing the risk of hurricanes and flooding in some regions, and droughts and forest fires in others. But despite telltale signs of their presence in the Pacific Ocean, including a reversal of ocean currents and large temperature rises, it can be hard to tell where else El Niños are having an effect.

A lost world has been found in Antarctica, preserved just the way it was when it was frozen in time some 14 million years ago.

Why the Sustainability Community Needs Social Networking
August 5, 2008 12:06 PM - , Triple Pundit

Over the course of the past 4 years I have had the opportunity to work with or share market strategies with executives at social networking companies such as LinkedIn, Spoke Software, Visible Path, and BranchIT. Of particular interest to me was the ability to develop and leverage what I referred to as "Relationship Capital Management"; the opportunity to develop, foster, and share relationships within an organization (or ecosystem) for the purposes of optimizing knowledge management and revenue generation. (I posted some columns on this trend a couple of years ago on "Relationships as Assets" and Relationship Capital Management and CRM). Viewing the challenges and opportunities in the sustainability market, it seems that social networking (both process and underlying technology) could play a large role in accelerating both awareness of key issues as well as potentially accelerate adoption.

The Greenest Desktop Computers Of 2008
August 5, 2008 11:04 AM - , MetaEfficient

At MetaEfficient I’ve been waiting for years to review some exciting green computers, and now finally in 2008, we’ve seen the introduction of some truly green PCs. Although the components of green PCs cost about 10% more than regular PCs, they retail for about the same price. You can jump ahead and see our list of the greenest PCs. Or you can read about the details of the green rating processes.

Untouched forests store 3 times more carbon: study

Untouched natural forests store three times more carbon dioxide than previously estimated and 60 percent more than plantation forests, said a new Australian study of "green carbon" and its role in climate change.

Motion-Sensing LED Lights: A Review
August 4, 2008 11:16 AM - , MetaEfficient

Motion-sensing LED lights — these lights are perhaps the most efficient lighting devices available today. They switch on whenever their infra-red sensors detect movement in a room — such as when someone begins to walk down a dark hallway. I’ve been testing them in my own home, and I’ve found them to be effective and non-obtrusive. At night, I’m able to go down two floors to the basement, without turning on any lights. The motion-sensing LEDs in the ceilings switch on as I move about the house.

What Do Squid Hear?
July 31, 2008 08:08 AM - Marine Biological Laboratory.

The ocean is a noisy place. Although we don’t hear much when we stick our heads underwater, the right instruments can reveal a symphony of sound. The noisemakers range from the low-frequency bass tones of a fish mating ritual to the roar of a motorboat. The study of how underwater animals hear is a growing topic in marine science, especially with regards to naval sonar and whales.

Algae Based Biofuels in Plain English: Why it Matters, How it Works.
July 30, 2008 11:25 AM - , Triple Pundit

Algae based biofuels. You've probably heard the term tossed around, and have maybe even said it in a sentence or two yourself. But have you ever really understood what it means, what the implications are, and on a basic level, how it works and if it has even the slightest chance to be a viable large scale player in supplying for our fuel needs? For many of you, I'm imagining the answer is no. Even I, a green business consultant, was quite fuzzy about it all. Until today.
