California, Feds Reject Volkswagen Recall "Fix"
January 14, 2016 07:16 AM - Jan Lee, Triple Pundit
Last week, the California Air Resources Board (CARB) said “no deal” to Volkswagen’s proposal to buy back some of the vehicles that were outfitted with cheat devices. According to CARB, the plan, which would see the recall of only a fraction of the 600,000 U.S. cars affected in the latest VW scandal, does “not adequately address overall impacts on vehicle performance, emissions and safety,” and would not fix the cars’ pollution problems quickly enough.
Pacific Northwest National Laboratory shows how nanoparticles impact immune cells
January 13, 2016 03:35 PM - Tom Rickey, Pacific Northwest National Laboratory
Scientists have shown that a process known as oxidative stress is at work during encounters between certain nanoparticles and immune cells, selectively modifying proteins on macrophages, a type of immune cell. The findings, by researchers at the Department of Energy's Pacific Northwest National Laboratory, were published in the journal ACS Nano.
While oxidative stress is a common way for cell damage to occur, the findings were a surprise in some ways.
"Oxidative stress is occurring selectively even at low levels of exposure to nanoparticles," said Brian Thrall, a nanotoxicology expert at PNNL and a corresponding author of the study. "We've demonstrated an approach that is sensitive enough to detect effects of nanoparticles on macrophages long before those cells die. This gives us the opportunity to understand the most sensitive cellular targets of oxidative stress and the pathways involved more completely than before.
"This is important information for understanding how nanoparticles can alter cell function and for beginning to identify functions that allow cells to adapt versus those that are potentially involved in adverse effects," Thrall added.
California Methane Leak leads to State of Emergency
January 11, 2016 07:26 AM - Mike Gaworecki, MONGABAY.COM
An ongoing methane gas leak at a facility in Southern California — what’s been called “the nation’s biggest environmental disaster since the BP oil spill” — has officially been declared an emergency by Governor Jerry Brown.
Natural gas, or methane, first started leaking from Southern California Gas Co.’s Aliso Canyon storage facility on October 23 last year.
Some 2,300 homes have been evacuated in nearby Porter Ranch, a neighborhood of Los Angeles, after residents began experiencing nosebleeds, rashes, headaches and other serious health impacts due to the gas leak and the sulfur-like smell that is blanketing their community.
As gas prices fall, consumers going back to less fuel efficient vehicles
January 9, 2016 08:04 AM - Scott Horsley, NPR
There were high-fives this week from Detroit to Washington, D.C., as carmakers celebrated record auto sales.
Americans bought 17.5 million cars and trucks in 2015. That's a huge turnaround from 2009, and the Obama administration cheered the rebound as vindication of the president's decision to rescue General Motors and Chrysler from bankruptcy.
"Because of the policy decisions that were made by this administration to place a bet on those workers, America has won, and our economy has been better for it," White House spokesman Josh Earnest told reporters Wednesday.
How you manage your email can affect your stress level
January 6, 2016 06:55 AM - BRITISH PSYCHOLOGICAL SOCIETY via EurekAlert.
New research suggests that it's not just the volume of emails that causes stress; it's our well-intentioned habits and our need to feel in control that backfires on us.
These are some of the key findings presented next week, Thursday 7 January 2016, at the British Psychological Society's Division of Occupational Psychology annual conference in Nottingham by Dr Richard MacKinnon from the Future Work Centre.
Will Styrofoam Get the Plastic Bag Treatment?
January 4, 2016 07:09 AM - Kevin Mathews, Care2
Say farewell to Styrofoam take-out containers in the nation’s capital. It’s been a few years in the making, but Washington, D.C. has finally enacted a firm ban on polystyrene food and beverage containers. Henceforth, all restaurants will have to provide biodegradable alternatives if they want to send their patrons home with leftovers.
Solar gaining on coal in India
January 4, 2016 06:15 AM - Chris Goodall, Ecologist
A KPMG study shows that the cost of solar power in India, revealed by public auctions, is barely half a cent above that of cheap local coal , writes Chris Goodall, with generators bids falling well below 5p (UK) / 7¢ (US) per kWh. The idea put about at COP21 that India and other poor but sunny countries need coal to develop their economies is fast running out of steam.
When the accountants have fully loaded the network and other costs PV ends up as very slightly cheaper than using lndian-mined coal. And, of course, this advantage will grow as solar gets cheaper.
Commentators eager to arrest the move towards renewable energy are facing increasing difficulties finding arguments for the continued use of fossil fuel.
Is the Pope right on climate change?
January 2, 2016 11:26 AM - Robert N. Stavins, Albert Pratt Professor of Business and Government; Member of the Board; Director, Harvard Project on Climate Agreements
Last June, Pope Francis released his much-anticipated encyclical on the environment, Laudato Si’, which received tremendous praise from diverse quarters. The same day, Coral Davenport, writing in the New York Times, noted that the papal encyclical "is as much an indictment of the global economic order as it is an argument for the world to confront climate change." Ms. Davenport quoted me (accurately) as saying that elements of the encyclical were unfortunately "out of step with the thinking and the work of informed policy analysts around the world." In this column, I will elaborate.
First of all, the Pope is to be commended for taking global climate change seriously, and for drawing more world attention to the issue. There is much about the encyclical that is commendable, but where it drifts into matters of public policy, I fear that it is — unfortunately — not helpful.
The long encyclical ignores the causes of global climate change: it is an externality, an unintended negative consequence of otherwise meritorious activity by producers producing the goods and services people want, and consumers using those goods and services. That is why the problem exists in the first place. There may well be ethical dimensions of the problem, but it is much more than a simple consequence of some immoral actions by corrupt capitalists. The document also ignores the global commons nature of the problem, which is why international cooperation is necessary.
Wind power on the rise in U.S.
December 22, 2015 07:22 AM - Jeff Brady, NPR
The U.S. wind power industry is celebrating after reaching a new milestone in November: 70 gigawatts (GW) of generating capacity.
"That's enough to power about 19 million homes," says Michael Goggin, senior director of research at the American Wind Energy Association (AWEA).
Space weather and the potential impacts on our infrastructures
December 19, 2015 07:10 AM - EUROPEAN COMMISSION JOINT RESEARCH CENTRE vie EurekAlert
The JRC has been looking into the risks of space weather impact on critical infrastructures. A new report explores the rail sector's vulnerability and the potential impacts, in particular through interdependencies with other infrastructures. Awareness among operators and regulators worldwide is currently limited and vulnerabilities across the rail sector need to be identified, authors say.
Solar activity affects the space environment surrounding the Earth. This so-called space weather can disrupt and damage critical infrastructure in space and on the ground, including satellites, aviation, road and marine transport, banking and power grids. Society relies on these infrastructures and services, which have become inter- dependent and are therefore more vulnerable to space weather.
