LED Light Bulbs are Good Illuminators

- Adam Clare 4 Comments

LED light bulbs are far kinder on the environment than old style incandescent light bulbs and they’re selling very well! Looks like good light is shining on the environment.

In the past year, though, lighting manufacturers have introduced LED bulbs in a shape Edison would recognize that put out a decent amount of good-quality light. They still don’t give off light from all sides as incumbent technologies do, but this latest generation of LEDs does a better job dispersing light, which means that you could use one (or a few) for overhead lighting.

The best part is that the prices are coming down. The 40-watt equivalent general light bulb from Lighting Science Group, which is dimmable, costs just under $20. You can buy it online now and in Home Depot stores later this month, along with the LEDs from other manufacturers, including a ceiling down light from Cree.

Town Bans Bottled Water

- Adam Clare 4 Comments

In what is probably a first for our planet, a small town in Australia has banned the selling of bottled water. This is absolutely fantastic to see because bottle water is an asinine idea for the developed world. Most bottled water comes form the same source as municipal tap water then shipped around via fuel-burning vehicles.
Bottle water is a fantastic model of inefficiency so it’s good to see this news coming out of Australia

“Every bottle today was taken off the shelf and out of the fridges so you can only now buy refillable bottles in shops in Bundanoon,” Dee told AFP.

The tiny town, two hours south of Sydney, voted in July to ban bottled water after a drinks company moved to tap into a local aquifer for its bottled water business.

“In the process of the campaign against that the local people became educated about the environmental impact of bottled water,” said Dee.

“A local retailer came up with this idea of well why don’t we do something about that and actually stop selling the bottled water and it got a favourable reaction,” he said.

Dee said the 2,000-person town had made international headlines with their bid, which he hoped would spur communities across the world to action.

Stem Cells Can Reverse Blindness

- Adam Clare 1 Comment

This looks promising: new research has proven that in some cases it is possible to use stem cells to reverse blindness.

In the study, published online by the New England Journal of Medicine, researchers took a small number of stem cells from a patient’s healthy eye, multiplied them in the lab and placed them into the burned eye, where they were able to grow new corneal tissue to replace what had been damaged. Since the stem cells are from their own bodies, the patients do not need to take anti-rejection drugs.

Adult stem cells have been used for decades to cure blood cancers such as leukemia and diseases like sickle cell anemia. But fixing a problem like damaged eyes is a relatively new use. Researchers have been studying cell therapy for a host of other diseases, including diabetes and heart failure, with limited success.

Bacteria Could Eat Oil Spills

- Adam Clare 5 Comments

In the future, oil spills could be partly cleaned up by bacteria that loves to eat all the dangerous goo in oil.

esearchers have discovered a new strain of bacteria that can produce non-toxic, comparatively inexpensive “rhamnolipids,” and effectively help degrade polycyclic aromatic hydrocarbons, or PAHs – environmental pollutants that are one of the most harmful aspects of oil spills.

Because of its unique characteristics, this new bacterial strain could be of considerable value in the long-term cleanup of the massive Gulf Coast oil spill, scientists say.

More research to further reduce costs and scale up production would be needed before its commercial use, they added.

The findings on this new bacterial strain that degrades the PAHs in oil and other hydrocarbons were just published in a professional journal, Biotechnology Advances, by researchers from Oregon State University and two collaborating universities in China. OSU is filing for a patent on the discovery.

“PAHs are a widespread group of toxic, carcinogenic and mutagenic compounds, but also one of the biggest concerns about oil spills,” said Xihou Yin, a research assistant professor in the OSU College of Pharmacy.

Organic Farmers can be Innovators

- Adam Clare

Here’s a neat piece of writing that argues that organic farmers can be a positive movement for than just food and why we should eat organic foods as a result.

“When people give up, money fills the void. When people hold the politicians accountable, they trump the power of money,” he said. “When we send people to Washington to represent us, we need to remind them who sent them there.”

“We can create a new wave of change in America,” said Hassebrook. “Organic farming is a big part of this change, but it won’t be automatic. We have to work for it.”

“Let our inspiration be the pioneers who first settled America. Those who succeeded were courageous. They made sacrifices to achieve their dreams. They were builders and entrepreneurs. They cared about their communities, which were comprised of a diversity of people with different languages and customs. They were farmers, carpenters, teachers, politicians and planners. They were visionaries who worked hard to achieve progress. They remained optimistic and were open to new ideas. Our challenge is to go forth and do good.”
