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.
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.”
Study shows most US roofs can support a solar system
April 14, 2016 07:40 AM - Sandia National Laboratories.
Most U.S. rooftops in good repair can take the weight of solar photovoltaic (PV) systems. That’s the conclusion of a three-year study by a research team led by Sandia National Laboratories.
“There is a misperception in the building industry that existing residential rooftops lack the strength to carry the weight load of rooftop solar photovoltaic installations,” said Sandia structural engineer Steve Dwyer. “Most existing well-built wooden rooftops can support PV system loads.”
Sandia took on the job of analyzing rooftop structural strength to address concerns raised in the U.S. Department of Energy’s (DOE) Solar America Cities program. The agency named 25 cities to promote adoption of solar technology at a comprehensive, local level through photovoltaics.
Better long-term outcomes for married cancer patients
April 11, 2016 11:51 AM - WILEY via EurekAlert
New research has uncovered a link between being married and living longer among cancer patients, with the beneficial effect of marriage differing by race/ethnicity and place of birth. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings have important public health implications, given the rising numbers of unmarried individuals in the United States in addition to the growing aging population.
For the analysis, a team led by Scarlett Lin Gomez, PhD, of the Cancer Prevention Institute of California, and María Elena Martínez, PhD, of the University of California, San Diego School of Medicine, assessed information on nearly 800,000 adults in California who were diagnosed in 2000 to 2009 with invasive cancer and were followed through 2012.
Reducing food waste could help mitigate climate change
April 11, 2016 07:33 AM - Potsdam Institute for Climate Impact Research
About a tenth of overall global greenhouse-gas emissions from agriculture could be traced back to food waste by mid-century, a new study shows. A team from the Potsdam Institute for Climate Impact Research for the first time provides comprehensive food loss projections for countries around the world while also calculating the associated emissions. Currently, one third of global food production never finds its way onto our plates. This share will increase drastically, if emerging countries like China and India adopt Western nutrition lifestyles, the analyses shows. Reducing food waste would offer the chance to ensure food security, which is well known. Yet at the same time it could help mitigate dangerous climate change.
Going vegetarian could save emissions and prevent 8 million deaths a year
March 31, 2016 06:51 PM - Marco Springmann, The Ecologist
Oxford researchers have quantified the benefits of the world becoming vegetarian, writes Marco Springmann. Their study shows that simple changes - like moving to diets low in meat and high in fruit and vegetables - could lead to significant reduction in mortality and health care costs, while cutting food sector greenhouse gas emissions by two thirds.
New research on the Rio Grande and impacts of long drought
March 23, 2016 11:00 AM - USGS Newsroom
New research can help water managers along the Rio Grande make wise decisions about how to best use the flow of a river vital for drinking water, agriculture and aquatic habitat. These studies also show how conditions from the prolonged drought in the West have affected the Rio Grande watershed.
The Rio Grande forms the world’s longest river border between two countries as it flows between Texas and Mexico, where it is known as the Rio Bravo. The river runs through three states in the U.S., beginning in southern Colorado and flowing through New Mexico and Texas before it forms the border with Mexico.
Parts of the Rio Grande are designated as wild and scenic, but most of the river is controlled and passes through several dam and reservoir systems during its 1,896 mile journey to the Gulf of Mexico. The river is managed through a complex system of compacts, treaties, and agreements that determine when and how much water is released along the river’s length.
Why women get more knee injuries than men
March 19, 2016 08:13 AM - UNIVERSITY OF TEXAS MEDICAL BRANCH AT GALVESTON via EurekAlert
Researchers from The University of Texas Medical Branch at Galveston have found that women who take the birth control pill, which lessen and stabilize estrogen levels, were less likely to suffer serious knee injuries. The findings are currently available in Medicine & Science in Sports & Exercise, the official journal of the American College of Sports Medicine.
Female athletes are 1.5 to 2 times more likely than their male counterparts to injure their anterior cruciate ligament, or ACL. The ACL is a ligament that connects the top and bottom portions of the knee. Damage to this ligament is a serious athletic injury that can be career altering. Return-to-play rates after ACL injury are as low as 49 percent among soccer players. Also, this injury may lead to lifelong issues with knee instability, altered walking gait and early onset arthritis.
Recycled water may be a solution to the California drought
March 15, 2016 08:37 AM - 3BL Media, Care2
The severity and impact of the drought remains top-of-mind among Californians. They are eager for long-term solutions that can help the state to achieve a water-secure future. California residents are overwhelmingly supportive of using treated wastewater, or recycled water, in their everyday lives, according to a statewide survey released today by Xylem Inc. The survey found that 76 percent of respondents believe recycled water should be used as a long-term solution for managing water resources, regardless of whether or not a water shortage continues.
Nearly half, or 49 percent of respondents, are very supportive of using recycled water as an additional local water supply and another 38 percent are somewhat supportive. The survey defined recycled water as former wastewater that has been treated and purified so that it can be reused for drinking purposes. Of survey respondents, 42 percent are very willing to use recycled water in their everyday lives and an additional 41 percent are somewhat willing. These findings confirm that there is a significant number of Californians who support the use of recycled water.
“We conducted this survey in an effort to better understand public perception about recycled water, and are very encouraged by the findings,” said Joseph Vesey, Xylem Senior Vice President who leads the Company’s North American commercial business. “With overwhelming support from the public, California is well-positioned to lead the U.S. in accelerating the availability and acceptance of recycled water. The state has the opportunity to champion a flexible framework that recognizes the unique needs of local communities as they work to establish water resource strategies that include sustainable solutions, such as recycled water.”
The Florida jail that is also an animal shelter
March 14, 2016 04:42 AM - Natalia Lima, Care2
Usually the word “jail” brings some harsh imagery to mind: barbed wire fences, orange jumpsuits and tall concrete walls. That’s not the case in the Key West, though. Ask a local about the jail, and the most likely image is Mo, an adorable and charismatic sloth who’s become the unofficial mascot of the Stock Island Detention Center, which doubles as a sanctuary for unwanted animals.
“All the animals here are either abandoned, abused, confiscated or donated,” Jeanne Selander, the caretaker for the facility, explains to Care2. “The animals are here because they need a forever home and we give them one.”
