By 2020 every light bulb is supposed to put out 45 lumens per watt. It's a Bush-era regulation that the current government wants to roll back.

Circadian rhythm lighting products won't fix body clock problems.

Calls came into emergency centers and even the Griffith Observatory from LA residents who described seeing a “giant silvery cloud.”

The only downside, of course, is that your self-lit holiday centerpiece actually would be a Frankenstein tree.

Using the newest scientific tools, the time needed to find out how best to fight an evolving pandemic has been greatly shortened

Ever wonder why humans don't have hair everywhere?

Seventy-two days after setting out from Istanbul, champion distance runner Kevin Lin Yi Jie and a small team of other athletes have covered 4,434 kilometers of their 10,00-kilometer goal: Running the

When Jerry wrote about Vincent Callebaut's proposed vertical farm for New York City, he called it a Locavore Wet Dream; I called it one of the silliest, most overwrought jump-the-shark vertical farm ideas ever

Artist Shilpa Joglekar works with rural communities in India and Taiwan to create much-needed play structures out of natural and recycled materials.

Woven from bamboo, this inviting structure transforms an empty lot in busy Taipei into a haven where neighborhood residents can relax and gather over a fire.

After more than a decade of in the field study, there has been no evidence of the rare and majestic leopard.

This design is a hybrid of existing concrete sea defenses that can hold a mangrove seedling inside.

Draped in moss, orchids, lilies, and ferns, this city bus transports riders to a whole new world.

Built as an extension for a local high school, this new urban space blends into its tree-lined surroundings.

It distorts sperm, makes it harder to get pregnant, and can lead to premature births and low birth weights -- yet another reason why cars and humans don't mix well.

This apartment's new design unifies the small space with a simple palette of materials over three levels.

Infrastructure doesn't have to look boring; this one references an old fable about a mountain utopia and features a modular steel frame.

Multifunctional zones and a sleeping loft enlarge this small apartment in Taipei.

Beach-side foam party gone out of control? Not quite. A shoreline north of Sydney, Australia was transformed into the "Cappuccino Coast," as one journalist put it, with foam swallowing up an entire beach and half the nearby buildings, including the

Maybe you've heard of the Dinosaur Tree? We first noted it back here. The Wollemi Pine (Wollemia nobilis) was previously only known from fossil records dating back 90 millions years, give or take a day. It was considered to have gone extinct about two

Climate change is powerfully symbolized by severe drought. Extended, widespread drought can make potable water scarce. Desalination plants are energy intensive and expensive to build and run: the several recently build or planned for Australia may

Australians may be world leaders in terms of greenhouse gas emissions, but with their new government signing Kyoto as one of its first acts in power, it seems change may well be in the air. So, is Australia about to go green in a big way? UK-based

Sydney claims the largest and most technologically advanced annual fireworks display on the planet, attracting more than one million people to the harbour foreshore, more than turn out for the fireworks in New York,

For all the talk of green design and eco lifestyles, it’s odd that Australia has so few events for businesses, organisations and institutions to showcase their wares in this area. Melbourne does have its very well attended Sustainable Living Festival,

It is an undisputed truth that the majority of American cities have incomplete bicycling infrastructures. This is perhaps especially true in Los Angeles, where

SRD Change is the annual exhibition of new graduate design and ideas that address our those issues which will impact our future. Like issues of sustainability, environmental change and responsibility, social equity and community. The Society for

It's a safe bet that few, if any, of Sydney's bicycle commuters go with penny farthings as their two-wheeler of choice. The outdated ride (popular in the 1870s) is most used these days for its retro value and the

Planning your holiday party schedule in New York City can be calendar jujitsu, what with work parties, friends parties, family parties, but there are also a few green themed parties that the sustainably minded New Yorker

Green Star is to Australian commercial and government buildings, what LEED (Leadership in Energy & Environmental Design) is to American structures of a similar ilk. The 5 Green Star rated Lilyfield Housing Redevelopment in inner

In our conventional, resource-intensive food and building industries, 'waste-free' may seem like an alien concept, which makes projects like Australia's Greenhouse all the more impressive. Touted as a

With everything happening in one space, studio apartments can often feel too cluttered. This Sydney apartments gets a space makeover with the addition of a clever multifunctional unit that partitions the space and stores things out of sight.

Instead of trashing these old treads, they have been made into a inter-looping work of art in the same station.

Are they good for everyone or just about making money and getting rid of workers?

A recent post that claimed readers absorb less from e-books. I wonder (and so do many commenters) if that's really true.

The Resilient Design Institute suggests we should all have six weeks of food in our homes. Too much or too little?

This is one area of measurement where perhaps the Americans, Liberians and Burmese get it right.

The extremely dated "It ain't easy being green" title of this Trulia survey actually misinterprets the data; judging by the questions they asked, it is perfectly easy being green; it just ain't cheap.

Which of these two images does your place look like?

It would save fuel and be safer for pedestrians and cyclists. But is it too complicated?

Some would pick a third option: vermin.

The results are often surprising.

The results of our annual survey are often surprising.

Our photo of the day comes from the 15th oldest U.S. national park.

You can't blame them for trying: With the White House set to change hands in less than a year's time - likely bringing on board a more eco-friendly administration - industry groups have been pressing the EPA to squelch stricter air-quality standards

Image from NASA updated: As many noted, I (idiotically) cited the Montreal Protocol's success here, which has nothing to do with reducing tropospheric ozone -- rather, it has to do with fixing the ozone layer. Thank you commenters, and my apologies for

Photo courtesy of Next Nature American Climate Values Survey Views on global warming may be more strongly politically and economically influenced than many may have hoped. The recently released results of the American Climate Values Survey, conducted

Good news: The ban on CFC-based asthma inhalers is rapidly approaching. Inhalers are going green and by December 31, all inhalers must be powered by hydrofluoroalkane (HFA) instead of the ozone-harming chlorofluorocarbons (CFCs).

In July of 2007, the East Coast was slammed by a record-setting heat wave. From New York City to Washington, DC, temperatures averaged above 90 degrees Fahrenheit, causing more than 40 deaths.

We rely on the sun for everything from powering up our electronics to basic heat and warmth for survival, but this massive star does more than just send light our way: It's a huge nuclear reactor with explosions, eruptions, storms,

Household cleaning products in the U.S. might soon be a little greener, thanks to a new rule in California that will require companies to reformulate products so they contain fewer volatile organic compounds, or
