Read the full story in the San Diego Union-Trubune.

Since November, Bill Stephens and his fellow water cops have issued more than 450 warnings and tickets to water wasters in Riverside County. They’ve targeted commercial, industrial and institutional customers in the Eastern Municipal Water District from Moreno Valley to Temecula.

This month, Stephens started to cite residents for excessively using water. After two warnings, homeowners will be fined $100 or more.

Mich. residents may pay extra for green power

Filed under: Energy, Great Lakes Region — Laura B. @ 10:27 am

Read the full story in the Lansing State Journal.

Saying it’s only fair, Michigan lawmakers plan to raise residential electricity bills and drop business rates so all customers are charged the true cost of their power.

But when it comes to figuring out who should pay what for new renewable energy requirements, the playing field wouldn’t be even.

Though residents account for one-third of Detroit Edison’s electric sales, they would contribute two-thirds of what Michigan’s largest utility could collect from customers for wind and other sources of alternative power under bills that have passed the House and Senate.

Residential customers of Consumers Energy account for just over one-third of sales yet would pay nearly half the maximum amount charged by the state’s second-biggest utility for renewable energy.

New insights into plants’ chemical defense mechanisms could lead to ecofriendly fungicides, pesticides, climate-proof crops

Filed under: Agriculture, Pest Management, Research — Laura B. @ 10:15 am

Read the full post at Biopact.

Even closely related plants produce their own natural chemical cocktails, each set uniquely adapted to the individual plant’s specific habitat. Comparing anti-fungals produced by tobacco and henbane, an international team of researchers discovered that only a few mutations in a key enzyme are enough to shift the whole output to an entirely new product mixture. Making fewer changes led to a mixture of henbane and tobacco-specific molecules and even so-called “chemical hybrids,” explaining how plants can tinker with their natural chemical factories and adjust their product line to a changing environment without shutting down intracellular chemical factories completely.

Scientists find signals of climate ‘tipping points’ in the past – relevance for carbon-negative energy

Filed under: Climate Change, Research — Laura B. @ 10:10 am

Read the full post at Biopact.

In the Earth’s history, periods of relatively stable climate have often been interrupted by sharp transitions to a contrasting state. For instance, glaciation periods typically ended suddenly. About 34 million years ago the Earth’s long lasting tropical state in which most recent life forms evolved, shifted abruptly and irreversibly to a cooler state with ice caps. This shift is known as the “Greenhouse-Icehouse-Transition”. Scientists long suspected that such sharp transitions – called “Abrupt Climate Change” (ACC) events – might be related to tipping points where positive feedback mechanisms lead to self-propelling change. They have now found typical warning signals that preceded the onset of such ACC events in the past. The findings are highly relevant to the current debate about how to mitigate climate change, and to the question of whether we should prepare for ACC.

Could bioenergy save the bees?

Filed under: Biofuels, Research, Wildlife — Laura B. @ 10:02 am

Read the full post at Biopact.

Over the past few months, stories about the dramatic die-off of bee colonies have grabbed headlines. In the U.S., the situation is critical, with the phenomenon – dubbed “colony collapse disorder” (CCD) – eliminating anywhere between 30 and 70 percent of all bee-hives. The situation is not much better in Europe. According to many scientists, the collapse of bee colonies is due to a complex cocktail of factors: the use of pesticides and insecticides, the emergence of a destructive mite which helps spread a deadly virus, a changing climate, the reliance on monocultures and a general lack of biodiversity. Tackling this crisis is crucial, because bees pollinate a whole range of crops – from oranges to soy beans – which provide 30% of all our food.

Perhaps the key to solving the problem can be found in growing energy crops. Here is how and why.

Sorry for the somewhat cryptic title, but with the recent announcement that researchers from Dartmouth College in New Hampshire have genetically engineered a bacteria that could aid in cellulosic ethanol production , and now this following announcement from the UK, it some seemed appropriate. Don’t know if there was any mental cross-pollination here, but the two discoveries share the same principle: By using thermophilic bacteria in the cellulosic ethanol production process, the whole thing can be made more energy efficient. Here are the details:

Science Daily reports that researchers from Guildford have developed a new strain of bacteria which can aid in the processing of cellulosic ethanol, making the procedure more efficient and less costly than traditional fermentation processes.

It’s been a pretty long road to making cellulosic ethanol commercially viable. As it stands there is one demonstration-scale cellulosic ethanol plant in the United States, and the the first commercial-scale biorefinery recently received approval back in July. Suffice it to say, cellulosic ethanol holds promise but is a work in progress.

Now comes word that researchers have engineered a bacteria which they say will make manufacturing the biofuel less expensive. The findings were published in the Proceedings of the National Academy of Science but Reuters gives the details for those of us who aren’t subscribers.

In much the same way that more ice/snow reflects UV rays instead of absorbing the heat the way the oceans do (think: feedback loop that results from melting polar ice caps), cities are now giving white roofs a second look as a way to cool cities and fight climate change. The Los Angeles Times reports that the Climate Change Research Conference, held this week, advised that if buildings and road surfaces in 100 of the largest cities in the US were covered with lighter and heat-reflective surfaces the savings could be massive. Roofs account for 25% and pavement account for 35% of surface area in cities.

States Battle Pesticides in Groundwater

Filed under: Agriculture, Environmental Health, Pest Management, Regulation, Water — Laura B. @ 9:40 am

Read the full story from ABC News.

Should we be worried about pesticides in groundwater contaminating the water we drink and the food we eat?

According to many public health and environment officials nationwide, the answer is yes.

In the last year and a half, public interest law firm Earthjustice has filed four federal lawsuits against the Environmental Protection Agency concerning the use of pesticides.

Many of the pesticides at the center of those legal battles are the same pesticides that recently surfaced as cause for concern in the state of Oregon. Of seven pesticides highlighted as contaminating groundwater in Oregon — three of which are listed as possibly or likely to cause cancer by the EPA — only two are are not subjects of Earthjustice’s pending lawsuits.

The continuing uncertainty of nano risks and regulations

Filed under: Nanotechnology, Regulation — Laura B. @ 9:38 am

Read the full story in ES&T.

In January 2008, the U.S. EPA launched a program that asks industries to submit available information about the nanomaterials that they manufacture or use. The voluntary program, called the Nanoscale Materials Stewardship Program (NMSP), was intended to provide basic information to help guide regulatory decisions. In the 7 months since its launch, 22 companies have reported to EPA, but critics say that the program is creeping along and that the human-health and environmental risks of this rapidly growing technology remain uncertain.

In the meantime, markets are filling up with products made of these small but powerful nanomaterials. From toothpaste to bacteria-free socks, and even including a swimsuit and running shoes used at the recent Olympics in Beijing, there are 803 products that reportedly contain nanomaterials, according to an analysis by the Woodrow Wilson International Center for Scholars’ Project on Emerging Nanotechnologies (PEN), a nonpartisan group.

Despite the promise of nanotechnology improving our lives, the potential risks of the technology remain largely uncertain. While researchers try to bridge the data gap to help risk assessors, experts around the world are emphasizing the need to regulate and oversee manufacturers to minimize potential risks from exposure to nanomaterials in workers, consumers, and wildlife.

Dams increase risk of alien aquatic invaders

Filed under: Invasive Species, Research, Water — Laura B. @ 9:37 am

Read the full story in ES&T.

In the unfolding global biodiversity crisis, freshwater ecosystems are losing even more species than terrestrial or marine environments are. Evidence points to dam construction and biological invasions as major culprits in these losses. In the U.S. alone, more than 80,000 major dams and 2.5 million smaller impoundments (such as reservoirs) have altered natural hydrology, and nearly 1000 introduced species now disrupt native aquatic systems. A new study published in the September issue of Frontiers in Ecology and the Environment (2008, 6, 357–363) concludes that dam construction and biological invasions are closely linked.
