Why aren't hybrid car owners showing more loyalty to hybrids?
April 29, 2016 07:51 AM - Leon Kaye, Triple Pundit
Hybrid cars have come a long way since the first frumpy Toyota Prius debuted in Japan almost 20 years ago. The same can be said for electric cars since GM rolled out its EV1 in the late 1990s, only to backtrack, repossess and destroy all of them, infuriating its fans in the process. There are now dozens of hybrid models, and they enjoyed a surge in saleswhen gasoline prices spiked in 2007 and again in 2012. But more recently, their sales overall have been on the decline. Meanwhile electric vehicles are becoming more sophisticated, are improving their range and have seen sales on the uptick while the automakers have become more competitive in their advertising.
As expected, hybrid cars’ sluggish sales numbers have much to do with the fact that oil prices have been in a two-year slump while conventional gasoline engines keep getting cleaner and more fuel efficient. When hybrids started becoming more popular a decade ago, it was often assumed that when it came time for a new upgrade, owners would stay loyal and trade in one hybrid car for another.
Carbon dioxide fertilization is greening the Earth

From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.
The impacts of air pollution on the developing fetus
April 27, 2016 11:31 AM - JOHNS HOPKINS UNIVERSITY BLOOMBERG SCHOOL OF PUBLIC HEALTH, via EurekAlert.
Even small amounts of air pollution appear to raise the risk of a condition in pregnant women linked to premature births and lifelong neurological and respiratory disorders in their children, new Johns Hopkins Bloomberg School of Public Health research suggests.
Fine particles from car exhaust, power plants and other industrial sources are breathed into the lungs, but the scientists have now found evidence of the effects of that pollution in the pregnant women's placentas, the organ that connects her to her fetus and provides blood, oxygen and nutrition. They found that the greater the maternal exposure to air pollution, the more likely the pregnant women suffered from a condition called intrauterine inflammation, which can increase the risk of a number of health problems for her child from the fetal stage well into childhood.
Chernobyl, three decades on
April 26, 2016 06:45 AM - Steven Powell, University of South Carolina
It was 30 years ago that a meltdown at the V. I. Lenin Nuclear Power Station in the former Soviet Union released radioactive contaminants into the surroundings in northern Ukraine. Airborne contamination from what is now generally termed the Chernobyl disaster spread well beyond the immediate environs of the power plant, and a roughly 1000-square-mile region in Ukraine, Belarus and Russia remains cordoned off, an exclusion zone where human habitation is forbidden.
The radiation spill was a disaster for the environment and its biological inhabitants, but it also created a unique radio-ecological laboratory.
Do you live in one of America's worst cities for air pollution?
April 25, 2016 07:16 AM - Llowell Williams, Care2
The American Lung Association has released its annual “State of the Air” report and its findings are troubling. Most Americans live in counties with air pollution so bad that it is a severe risk to their health. According to the report, that means 166 million people are at risk of an early death and significant health problems including asthma, developmental damage and cancer.
Without a doubt the most concerning discovery made by the American Lung Association was that short-term particle pollution had increased sharply since last year’s report: “Short-term spikes” of particle pollution hit record levels in seven of the 25 most polluted U.S. cities in this period.
Australian river on fire with fracked coal seam gas
April 23, 2016 03:13 PM - Australian Greens MP Jeremy Buckingham, The Ecologist
So much methane is bubbling into a river surrounded by hundreds of fracking wells that it's a fire hazard! Local campaigners blame the coal seam gas industry for the gas releases which are spreading along Queensland's river Condamine and gaining in intensity.
So much methane gas is now bubbling up through the Condamine River in Queensland, Australia that it exploded with fire and held a large flame.
Gas seeping into the river began shortly after coal seam gas operations started nearby and is growing in volume and the stretch of river affected is expanding in length.
VW agrees to buy back or "fix" 500,000 cars in North America
April 22, 2016 12:23 PM - Jan Lee, Triple Pundit
Volkswagen agreed to fix or buy back some 500,000 vehicles caught up in the crisis. What wasn’t agreed upon is how much the company should pay in fines and compensation to consumers affected by the crisis.
Ocean currents push phytoplankton and pollution faster than thought
April 20, 2016 06:50 AM - Princeton University
The billions of single-celled marine organisms known as phytoplankton can drift from one region of the world's oceans to almost any other place on the globe in less than a decade, Princeton University researchers have found.
Unfortunately, the same principle can apply to plastic debris, radioactive particles and virtually any other man-made flotsam and jetsam that litter our seas, the researchers found. Pollution can thus become a problem far from where it originated within just a few years.
Is your home making you sick?
April 20, 2016 06:40 AM - University of Surrey
New research in the journal Science of the Total Environment has highlighted the dangerous effects of indoor pollution on human health, and has called for policies to ensure closer monitoring of air quality.
A collaborative effort of European, Australian and UK researchers, led by the University of Surrey, assessed the harmful effects of indoor pollution in order to make recommendations on how best to monitor and negate these outcomes.
Dr Prashant Kumar of the University of Surrey explained, “When we think of the term ‘air pollution’ we tend to think of car exhausts or factory fumes expelling grey smoke. However, there are actually various sources of pollution that have a negative effect on air quality, many of which are found inside our homes and offices. From cooking residue to paints, varnishes and fungal spores the air we breathe indoors is often more polluted than that outside.”
Microbots Could Play Key Role in Cleaning Up Our Water Systems
April 18, 2016 06:56 AM - Lizabeth Paulat, Care2
What if we could not only clean up the heavy metals in our water systems, but also recycle those metals and reuse them?
A new study from the Institute for Intelligent Systems in Germany and the Institute for Bioengineering of Catalonia in Spain suggests that, soon, we might be doing just that.
