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.

A vaccine for parasitic intestinal worms has been shown to be safe in Brazilian clinical trials, according to its US developer. Hookworm parasites infect more than 600 million people worldwide, attaching themselves to the intestines to feed on blood. Infection can lead to iron deficiency and capillary damage, and may retard children’s growth and mental development.

A 600,000 year long continental archive revealed in Near East study

The University of Bonn

If you want to see into the future, you have to understand the past. An international consortium of researchers under the auspices of the University of Bonn has drilled deposits on the bed of Lake Van (Eastern Turkey) which provide unique insights into the last 600,000 years. The samples reveal that the climate has done its fair share of mischief-making in the past. Furthermore, there have been numerous earthquakes and volcanic eruptions. The results of the drilling project also provide a basis for assessing the risk of how dangerous natural hazards are for today's population. In a special edition of the highly regarded publication Quaternary Science Reviews, the scientists have now published their findings in a number of journal articles. In the sediments of Lake Van, the lighter-colored, lime-containing summer layers are clearly distinguishable from the darker, clay-rich winter layers — also called varves. In 2010, from a floating platform an international consortium of researchers drilled a 220 m deep sediment profile from the lake floor at a water depth of 360 m and analyzed the varves. The samples they recovered are a unique scientific treasure because the climate conditions, earthquakes and volcanic eruptions of the past 600,000 years can be read in outstanding quality from the cores.

Another Brick In The Toilet

November 25th, 2014
On the ENN blog we are always talking about simple ways to reduce our impact, whether it is weather proofing our home, increasing what we recycle, or remembering to turn off the lights after we leave the room. While browsing our affiliate Care2’s website I came upon the suggestion of “dropping a brick” into your toilet as a way to save water. “Hold up, “you say. “Dropping a brick in the toilet, is that some kind of poop pun?” Yes it is, but it is also a strategy to reduce the amount of water wasted while flushing the toilet.

Organic Dry Cleaning?

November 15th, 2014
I dread my semi-annual trip to the dry cleaners. Unfortunately, it is inevitable, unless of course I unfashionably decide to live the rest of my life draped in garbage bags in order to deter ever fleck of dirt and every ounce of tomato sauce.  Lately, while going on the dreaded task, I have noticed a […]
