How the environment can trigger disease
November 25, 2014 03:00 PM - ClickGreen Staff, ClickGreen
Using a new imaging technique, National Institutes of Health researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. These damaged molecules trigger cell death that produces some human diseases, according to the researchers. The work provides a possible explanation for how one type of DNA damage may lead to cancer, diabetes, hypertension, cardiovascular and lung disease, and Alzheimer’s disease.
World Bank warns effects of warming climate now unavoidable

As the planet continues to warm, heat-waves and other extreme weather events that today occur once in hundreds of years, if ever, will become the “new climate normal,” creating a world of increased risks and instability, a new World Bank study warns.
The consequences for development would be severe as crop yields decline, water resources shift, sea-levels rise, and the livelihoods of millions of people are put at risk, according to a new scientific report released today by the World Bank Group.
Farms as sites for renewable energy
November 21, 2014 07:00 AM - ClickGreen Staff, ClickGreen
UK farms could be a major player in a shift towards a resilient, low-carbon energy system, according to a landmark report launched today by the Farm Power coalition.
The coalition, which is made up of a growing number of farming bodies, businesses and NGOs, are now calling on policymakers and other key stakeholders, including supermarkets, to support the renewable energy vision.
The research carried out by sustainability non-profit Forum for the Future, which leads the coalition, and Nottingham Trent University, found there was at least 10GW of untapped resource across UK farms – equivalent to more than three times the installed capacity of the proposed new nuclear power plant at Hinkley Point C.
UK unveils first waste-fueled bus
November 20, 2014 07:49 AM - ClickGreen Staff, ClickGreen
The UK's first ever bus powered on human and food waste has taken to the road today which engineers believe could provide a sustainable way of fuelling public transport - cutting emissions in polluted towns and cities. The 40-seater Bio-Bus, which runs on gas generated through the treatment of sewage and food waste that's unfit for human consumption, helps to improve urban air quality as it produces fewer emissions than traditional diesel engines. Running on waste products that are both renewable and sustainable, the bus can travel up to 300km on a full tank of gas.
How Sustainable is the Modern Diet?
November 14, 2014 07:57 AM - ClickGreen Staff, ClickGreen
The world is gaining weight and becoming less healthy, and global dietary choices are harming the environment, according to a new research report. Those are among the findings of a paper co-authored by David Tilman, a professor in the Bren School of Environmental Science & Management, and Michael Clark, a graduate student at the University of Minnesota, where Tilman is a professor. In “Global Diets Link Environmental Sustainability and Human Health,” published today in the journal Nature, the researchers find that rising incomes and urbanization around the world are driving a global dietary transition that is, in turn, diminishing the health of both people and the planet.
30-year study reveals startling decline in European birds
November 6, 2014 03:09 PM - ClickGreen Staff, ClickGreen
Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species, according to the findings of a new study. However, the research conducted by the University of Exeter, the RSPB and the Pan-European Common Bird Monitoring Scheme (PECBMS), found numbers of some less common birds have risen.
What could be better than LED lighting?
October 27, 2014 12:13 PM - ClickGreen staff, ClickGreen
Even as the 2014 Nobel Prize in Physics has enshrined light emitting diodes (LEDs) as the single most significant and disruptive energy-efficient lighting solution of today, scientists around the world continue unabated to search for the even-better-bulbs of tomorrow.
Electronics based on carbon, especially carbon nanotubes (CNTs), are emerging as successors to silicon for making semiconductor materials. And they may enable a new generation of brighter, low-power, low-cost lighting devices that could challenge the dominance of light-emitting diodes (LEDs) in the future and help meet society's ever-escalating demand for greener bulbs.
Fracking Footprint Seen From Space

An unexpectedly high amount of the climate-changing gas methane, the main component of natural gas, is escaping from the Four Corners region in the US Southwest, according to a new study by the University of Michigan and NASA. The researchers mapped satellite data to uncover the nation's largest methane signal seen from space. They measured levels of the gas emitted from all sources, and found more than half a teragram per year coming from the area where Arizona, New Mexico, Colorado and Utah meet. That's about as much methane as the entire coal, oil, and gas industries of the United Kingdom give off each year.
How "Natural" are Naturally Labeled Foods?
October 8, 2014 08:46 AM - ClickGreen Staff, ClickGreen
A wide variety of packaged food that carry the label "natural" on US supermarket shelves were found to contain substantial amounts of genetically modified organisms (GMO), according to product testing organization Consumer Reports. Tests on dozens of common food products including breakfast cereals, crisps and infant formula found almost all of them contained recognizable levels of GMOs. The research results has led to Consumer Reports to now call for the mandatory labeling of GMOs in food and a ban on the "natural" label, which suggest products don't contain the controversial ingredients.
How Yogurt Protects Us From Environmental Poisoning

Yogurt containing probiotic bacteria successfully protected children and pregnant women against poisoning from heavy metal exposure, according to a new study. Working with funding from the Bill and Melinda Gates Foundation, Canadian and Tanzanian researchers created and distributed a special yogurt containing Lactobacillus rhamnosus bacteria and observed the outcomes against a control group.
