Why you should exercise with friends

Exercising together brings us closer to one another, while exercising with those close to us improves our performance. Those are the conclusions of an Oxford University study published this Friday in the journal PLoS ONE.
Food's impact on our brain found to be similar to drugs
August 31, 2015 07:58 AM - EUROPEAN COLLEGE OF NEUROPSYCHOPHARMACOLOGY via EurekAlert
An international group of researchers have found that food craving activates different brain networks between obese and normal weight patients. This indicates that the tendency to want food may be 'hard-wired' into the brain of overweight patients, becoming a functional brain biomarker.
Obesity is one of the most difficult problems facing modern society. Treating obesity is a health priority, but most efforts (aside from bariatric surgery) have met with little success. In part, this is because the mechanisms associated with the desire to eat are poorly understood. Recently, studies are beginning to suggest that the brain mechanisms underlying obesity may be similar to those in substance addiction, and that treatment methodologies may be approached in the same way as other substance addictions, such as alcohol or drug addiction.
Even safe levels of air pollution found to have health impacts in European study
August 30, 2015 07:40 AM - EUROPEAN SOCIETY OF CARDIOLOGY via EurekAlert
Particulate matter and NO2 air pollution are associated with increased risk of severe heart attacks despite being within European recommended levels, according to research presented at ESC Congress today by Dr Jean-Francois Argacha, a cardiologist at University Hospital Brussels (UZ Brussel-Vrije Universiteit Brussel), in Belgium.1
"Dramatic health consequences of air pollution were first described in Belgium in 1930 after the Meuse Valley fog," said Dr Argacha. "Nowadays, the World Health Organization (WHO) considers air pollution as one of the largest avoidable causes of mortality. Besides the pulmonary and carcinogenic effects of air pollution, exposition to air pollution has been associated with an increased risk in cardiovascular mortality."
Study links air pollution to low GPAs
August 28, 2015 09:01 AM - University of Texas at El Paso
A University of Texas at El Paso (UTEP) study on children’s health has found that fourth and fifth graders who are exposed to toxic air pollutants at home are more likely to have lower GPAs.
Plastic particles found in cosmetics
August 26, 2015 10:12 AM - Plymouth University
Everyday cosmetic and cleaning products contain huge quantities of plastic particles, which are released to the environment and could be harmful to marine life, according to a new study. Research at Plymouth University has shown almost 100,000 tiny ‘microbeads’ – each a fraction of a millimetre in diameter – could be released in every single application of certain products, such as facial scrubs.

Individuals previously diagnosed with heart disease may be less likely to experience heart failure, heart attacks, or stroke, or to die from these events, if they have higher blood levels of two very closely related proteins, according to a new study led by a UC San Francisco research team.
One of these proteins, known as GDF11, has attracted great interest since 2013, when researchers showed that it could rejuvenate old mice. Based on these findings, scientists have speculated that drugs that increase GDF11 levels might reverse physiological manifestations of aging that lead to heart failure in people.
Access to nature may help you sleep better
August 25, 2015 04:08 PM - University of Illinois
Men and persons age 65 and older who have access to natural surroundings, whether it’s the green space of a nearby park or a sandy beach and an ocean view, report sleeping better, according to a new University of Illinois study published in Preventive Medicine.
Cellphone location data shown to help track infectious disease
August 22, 2015 07:22 AM - B. Rose Huber, Woodrow Wilson School of Public and International Affairs, Princeton University
Tracking mobile phone data is often associated with privacy issues, but these vast datasets could be the key to understanding how infectious diseases are spread seasonally, according to a study published in the Proceedings of the National Academy of Sciences.
Princeton University and Harvard University researchers used anonymous mobile phone records for more than 15 million people to track the spread of rubella in Kenya and were able to quantitatively show for the first time that mobile phone data can predict seasonal disease patterns.
Harnessing mobile phone data in this way could help policymakers guide and evaluate health interventions like the timing of vaccinations and school closings, the researchers said. The researchers' methodology also could apply to a number of seasonally transmitted diseases such as the flu and measles.
Scientists Warn of Air Pollution Risks in West Africa
August 21, 2015 01:55 PM - University of York
New research by European and African scientists, including a team from the University of York, warns of the risks posed by the increasing air pollution over the cities of West Africa – amid fears it could have an impact on human health, meteorology and regional climate.
Air pollution in China is bad, REALLY bad!
August 20, 2015 08:28 AM - RP Siegel
There can be no question that the epic story of our time is our struggle to endure against the threatening demons of our own creation. In that story, China must be the sleeping giant. As the story opens, the giant awakens, searching for a way to improve the livelihood of his people, inadvertently trampling on a number of the Earth’s delicate structures in doing so. Realizing this, a second awakening occurs. But can the giant change direction quickly enough, before too much harm is done?
The damage that re-directed the giant was the realization that fossil fuel emissions, particularly from coal-fired power plants, are pushing atmospheric carbon levels to dangerously high levels. China’s emissions have grown 7 percent annually — far faster than the rest of the world, which is growing at 2.8 percent. Now that we all realize that emissions have to start decreasing, fast, China has pledged to achieve peak emissions by 2030, after which its emissions will begin to decrease.
