By licking a wound it heals faster -- this is not simply popular belief, but scientifically proven. Our saliva consists of water and mucus, among other things, and the mucus plays an important role. It stimulates white blood cells to build a good defense against invaders, according to a group of researchers at Lund University in Sweden together with colleagues from Copenhagen and Odense in Denmark.

"White blood cells are among other places located in the oral mucosa, and they represent the body's first line of defence against infectious agents. The mucus in the mouth causes the white blood cells to throw out a 'net' that traps bacteria", explains Ole Sørensen from the Division of Infection Medicine.

A study just published by the Harvard T.H. Chan School of Public Health has linked a building’s indoor air quality directly to its occupants’ cognitive function. Cognitive function is defined as the cerebral activities that lead to knowledge including acquiring information, reasoning, attention, memory and language.

The revolutionary finding of this study is that lowering indoor air levels of carbon dioxide and volatile organic compounds (VOCs) improves human cognitive function. In other words: Cleaner air makes us smarter!

A new study to be published online November 5 in the American Journal of Psychiatry casts a shadow on light therapy's status as the gold standard for treating SAD, or seasonal affective disorder. 

While the treatment was effective at addressing acute episodes of SAD, a SAD-tailored version of cognitive-behavioral therapy (CBT) was significantly better at preventing relapse in future winters, the study found. Led by University of Vermont psychology professor Kelly Rohan, the research initiative, funded by a $2 million grant from the National Institute of Mental Health, is the first large scale study to examine light therapy's effectiveness over time. 

The Volkswagen emissions-cheating scandal widened Monday (2 November) as US regulators said the German automaker also included illegal "defeat devices" on its larger 3.0 liter diesel engines over the past three years.

But the Environmental Protection Agency said it had discovered in its investigation that various six-cylinder 3.0 liter diesel VW Touareg, Porsche Cayenne and Audis from the 2014-2016 model years and distributed in the United States had also been rigged with the software.

As governments around the world continue to push the concept of electric vehicles there are growing calls for all government buildings to offer free EV charging. This would certainly kickstart the concerns regarding EV charging networks which seems to be at the forefront of the minds of many sceptics. So, how would this concept work and is it really viable?

Helping the electric vehicle industry

While many governments around the world are doing a significant amount of work behind the scenes to help the electric vehicle market, could they do more? It would be wrong to suggest that all government buildings do not offer any form of electric vehicle charging but for many people these services are few and far between. When you consider that countries such as the UK employ more than 50% of the workforce in public services there must be an enormous scope to assist the industry?

Earth has just had the hottest January-September on record, the United Nations World Meteorological Organization (WMO) said today, adding that the average air and sea temperatures in September logged the greatest rise above monthly average in the 136-year historical record.

According to a press release from WMO, the Global Climate Report from the United States National Oceanic and Atmospheric Administration (NOAA), the globally averaged air temperature over land and sea surface temperature for September was 0.90°C (1.62°F) above the 20th century average temperature. Record warmth was observed across much of South America and parts of Africa, the Middle East, Europe, and Asia.

Volkswagen’s use of software to evade emissions standards in more than 482,000 diesel vehicles sold in the U.S. will directly contribute to 60 premature deaths across the country, a new MIT-led study finds.

In September, the Environmental Protection Agency discovered that the German automaker had developed and installed “defeat devices” (actually software) in light-duty diesel vehicles sold between 2008 and 2015. This software was designed to sense when a car was undergoing an emissions test, and only then engage the vehicle’s full emissions-control system, which would otherwise be disabled under normal driving conditions — a cheat that allows the vehicles to emit 40 times more emissions than permitted by the Clean Air Act.

That amount of excess pollution, multiplied by the number of affected vehicles sold in the U.S. and extrapolated over population distributions and health risk factors across the country, will have significant effects on public health, the study finds.

The pollution-cheating scandal that has engulfed auto giant Volkswagen is turning up the heat on the German government to make more determined headway in its self-declared "electromobility" goals, analysts say.

The "bitter irony" of the scam that has rocked the automobile sector around the world and plunged the once-respected carmaker into a major crisis, is that the billions of euros VW could potentially face in fines"could have been used to finance an entire electric car programme," complained Environment Minister Barbara Hendricks recently.

Over the past six years, Berlin has put up €1.5 billion for research into an electric car, the minister pointed out. And her ministry is looking into a series of measures to promote the electric car, such as tax incentives and purchase subsidies.

Dancing in time with others raises your pain threshold, Oxford University researchers have found.

A team from the University's Experimental Psychology and Anthropology Departments wanted to see whether our feelings of social closeness when dancing with others might be linked to endorphins – the body’s 'feel good' chemicals.

Endorphins are neurotransmitters that form part of the brain’s pain control system, but they are also implicated in social bonding. Dr Bronwyn Tarr explained: 'Dance is an important activity around the world, and it could be a way to connect with other people and feel socially bonded. We wanted to see the effect of high and low energy, and synchronised and unsynchronised dancing had on both pain threshold and the sense of bondedness to fellow group-members.'

An estimated annual 'tax gap' subsidy of some €16 billion for diesel over petrol has made Europe the world's largest market for diesel cars - but the Volkswagen scandal has put the national tax schemes supporting this industry at risk.

“There is no reason to keep subsidising this sector," Carlos Calvo, policy analyst at Transport & Environment, told EurActiv on Monday (26 October). The efficiency of petrol-fuelled cars has improved significantly in recent years, while the diesel industry has reduced its nitrogen-oxide emissions only very slowly.
