Bad air quality is deadly
February 13, 2016 07:18 AM - UNIVERSITY OF BRITISH COLUMBIA via EurekAlert
New research shows that more than 5.5 million people die prematurely every year due to household and outdoor air pollution. More than half of deaths occur in two of the world's fastest growing economies, China and India.
Power plants, industrial manufacturing, vehicle exhaust and burning coal and wood all release small particles into the air that are dangerous to a person's health. New research, presented today at the 2016 annual meeting of the American Association for the Advancement of Science (AAAS), found that despite efforts to limit future emissions, the number of premature deaths linked to air pollution will climb over the next two decades unless more aggressive targets are set.
"Air pollution is the fourth highest risk factor for death globally and by far the leading environmental risk factor for disease," said Michael Brauer, a professor at the University of British Columbia's School of Population and Public Health in Vancouver, Canada. "Reducing air pollution is an incredibly efficient way to improve the health of a population."
Obama Administration's "Clean Power Plan" dealt a setback by the Supreme Court
February 10, 2016 07:03 PM - Jan Lee, Triple Pundit
The Obama administration’s Clean Power Plan suffered a setback on Tuesday when the Supreme Court granted a stay to the program. In a 5-4 decision, the court sided in favor of petitioning states, utilities and coal companies that claimed that the federal government was overreaching its powers when it attempted to establish a national plan to move away from fossil-fuel based power. Requests for the Supreme Court to impose the stay were submitted in January after an appeals court ruled that the plan could proceed while legal challenges were being heard.
The Supreme Court’s ruling is an about-face to the U.S. Court of Appeals for the District of Columbia Circuit, and it comes at a critical time for the Obama administration’s clean energy program, especially in light of the upcoming elections in November. While the administration can appeal the Supreme Court’s order, arguments would not be considered until June and, pending acceptance by the higher court, likely wouldn’t be scheduled until October or later this year. That leaves the fate of the Clean Power Plan in the hands of the upcoming presidency.
Warmer climate contributes to spread of the Zika virus
February 10, 2016 09:51 AM - Nadia Pontes, The Ecologist
The Aedes mosquitos that carry the Zika virus and dengue fever are not just perfectly adapted to life in cities, writes Nadia Pontes. They are also being helped along by warming climates which increase their range. It's time to get serious about the health implications of a hotter planet.
Global warming affects the abundance and distribution of disease vectors. As regions that used to be drier and colder start to register higher temperatures and more rain, mosquitoes expand their breeding areas, which increases the number of populations at
The explosion in the number of Latin American cases of microcephaly - a congenital condition associated with maldevelopment of the brain - has become an international emergency due its "strongly suspected"link with the rapidly spreading Zika virus, according to the World Health Organisation(WHO).
Over 50 Percent of the World Breathes in Toxic Air
February 9, 2016 07:13 AM - Kevin Mathews, Care2
Everyone needs clean air to survive, yet somehow it is not an internationally recognized human right. That probably has something to do with the fact that over half of the world’s population live in areas where they breathe in toxic air. Altogether, that means there are more than 3.5 billion people inhaling dangerous air into their lungs on a daily basis.
Who would have guessed this? Study finds vacations can lead to weight gains!
February 5, 2016 03:38 PM - Universtiy of Georgia via EurekAlert
A week's vacation may leave many adults with a heavier midsection--extra weight that can hang around even six weeks post-vacation.
A faculty member in the University of Georgia's College of Family and Consumer Sciences found that adults going on a one- to three-week vacation gained an average of nearly 1 pound during their trips. With the average American reportedly gaining 1-2 pounds a year, the study's findings suggest an alarming trend.
"If you're only gaining a pound or two a year and you gained three-quarters of that on a one- to three-week vacation, that's a pretty substantial weight gain during a short period of time," said Jamie Cooper, an associate professor in the college's department of foods and nutrition.
Seafood Consumption May Play a Role in Reducing Risk for Alzheimer's
February 3, 2016 07:01 AM - National Institute of Environmental Health Sciences
New research published Feb. 2 in the Journal of the American Medical Association found that older adults with a major risk gene for Alzheimer’s disease known as APOEɛ4 who ate at least one seafood serving per week showed fewer signs of Alzheimer’s-related brain changes. In contrast, this association was not found in the brains of volunteers who ate fish weekly but did not carry the risk gene.
Air pollution in Europe and the EU lack of action
February 3, 2016 06:40 AM - Jean Lambert, Molly Scott Cato & Keith Taylor, The Ecologist
Air pollution from vehicles is killing tens of thousands of people every year in the UK alone, write Jean Lambert, Molly Scott Cato & Keith Taylor, an outrage set into stark focus by VW's 'test cheating'. The EU's response? To relax tests and allow cars to be more polluting - with the full support of the UK government.
Rather than clamping down on the car industry's irresponsible approach to pollution, EU governments and the Commission instead want to rewrite existing law, providing loopholes which will allow cars to legally pollute more.
Faced with a public health crisis, responsible for nearly half a million premature deaths in Europe each year, we would expect an emergency response.
Olfactory receptors found in Human blood
February 1, 2016 10:50 AM - RUHR-UNIVERSITY BOCHUM via EurekAlert
Human blood cells have olfactory receptors that respond to Sandalore. This could provide a starting point for new leukaemia therapies, as researchers from Bochum report in a current study.
Olfactory receptors exist not only in the nose, but also in many other parts of the body, including the liver, the prostate and the intestines. Researchers headed by Prof Dr Dr Dr Hanns Hatt from the Ruhr-Universität Bochum have now demonstrated them in white blood cells in humans.
Together with colleagues from the Essen University Hospital, the Bochum-based group identified the receptor OR2AT4 in a cultivated cell line, taken from patients suffering from chronic myelogenous leukaemia. The researchers identified the same receptor in white blood cells isolated from blood freshly obtained from patients suffering from acute myeloid leukaemia. It is activated by Sandalore, a synthetic odorant with a sandalwood note.
What do we know about the Zika virus?
January 29, 2016 07:19 AM - Harvard School of Public Health
The mosquito-borne Zika virus has been linked to a surge in cases of birth defects in Brazil, and is spreading in other countries in the southern hemisphere. Flaminia Catteruccia, associate professor of immunology and infectious diseases at Harvard T.H. Chan School of Public Health, says the virus may have adapted to the human environment and mutated.
Meat consumption and climate change linked by EU study
January 28, 2016 07:22 AM - Sarantis Michalopoulos, EurActiv
The overconsumption of meat will inevitably push global temperatures to dangerous levels, a recent study has warned, urging reluctant governments to take action.
The world's rapidly expanding population is posing a huge challenge to farmers. A reportpublished in November 2015 by Chatham House, and the Glasgow University Media Group, examined the interconnection between meat and dairy consumption with climate change.
Nearly one-third of the world's cultivated land is being used to grow animal feed. In the EU alone, 45% of wheat production is used for this purpose, with 30% of overall use met by imports.
