Pollution Linked to Lethal Sea Turtle TumorsLast Updated on 2014-10-01 11:29:48DURHAM, N.C. -- Pollution in urban and farm runoff in Hawaii is causing tumors in endangered sea turtles, a new study finds.
The study, published Tuesday in the peer-reviewed open-access journal PeerJ, shows that nitrogen in the runoff ends up in algae that the turtles eat, promoting the formation of tumors on the animals’ eyes, flippers and internal organs. CLICK HERE TO READ MORE

Water contaminant linked to children's low IQs Last Updated on 2014-10-01 11:24:46Babies born to mothers with high levels of perchlorate during their first trimester are more likely to have lower IQs later in life, according to a new study.
The research is the first to link pregnant women's perchlorate levels to their babies’ brain development. It adds to evidence that the drinking water contaminant may disrupt thyroid hormones, which are crucial for proper brain growth.
Perchlorate, which is both naturally occurring and manmade, is used in rocket fuel, fireworks and fertilizers. It has been found in 4 percent of U.S. public water systems serving an estimated 5 to 17 million people, largely near military bases and defense contractors in the U.S. West, particularly around Las Vegas and in Southern California.

ClimateLast Updated on 2014-10-01 10:48:54
Climate is the typical pattern of conditions of the earth’s atmosphere over a given region, as defined by factors such as temperature, air pressure. humidity, precipitation, sunlight, cloudiness, and winds. The World Meteorological Organization defines climate as "the statistical description in terms of the mean and variability of relevant quantities over a period of time," where an appropriate period is typically at least thirty years. Climate can be assessed at different, overlapping geographic regions. For example, Earth is thought to have a climate that is distinct from that of other planets, while different regions of Earth are also thought to have distinct climate types. Climate is often described as the "average" conditions; however, since daily and seasonal variability (including extremes) are critical determinants, using the term... More »
