COLUMBUS, Ohio – Scientists have designed a screening tool that provides a fast, easy and relatively inexpensive way to predict levels of a specific toxin in lakes that are prone to blue-green algal blooms.
Blue-green algae is not your average pond scum – rather than consisting of plant-like organisms, blue-green algae actually are cyanobacteria, and some species are linked to the production and release of the toxin microcystin into the water. Human exposure to the toxin through drinking or recreational water contact can threaten public health by causing liver damage, neurological problems and gastrointestinal illness in humans. (more…)
Pollution is an unfortunate by-product of our ever-changing society. Air, water and even noise pollution can take a toll on any person’s body, without their knowledge. Fortunately, there ARE ways to fight the effects of pollution in your body, in order to maintain a healthy lifestyle. There are also helpful tips to decrease the toxins that are invading your body, which could potentially cause harmful consequences later in life. Here’s what you need to know!
The Consequences of Pollution
Impure surroundings affect the lungs, heart, cardiovascular system, immune system, and organs when dangerous toxins are inhaled, consumed or absorbed by the skin or airways. Respiratory ailments, such as colds, flu, pneumonia, emphysema and bronchitis occur often because of these. The chances of contracting asthma and COPD or Chronic Obstructive Pulmonary Disease are also more likely. Tainted environments also contribute to allergies, headaches, migraines, and skin disorders such as eczema, acne, melanoma cancer and premature aging.(more…)
GAINESVILLE, Fla. — Paving a highway across South America is providing lessons on the impact of road construction elsewhere.
That’s what a University of Florida researcher and his international colleagues have determined from analyzing communities along the Amazonian portion of the nearly 4,200-mile Interoceanic Highway, a coast-to-coast road that starts at ports in Brazil and will eventually connect to ones in Peru.

Glacier lilies and broad-tailed hummingbirds out of sync
The glacier lily as it’s called, is a tall, willowy plant that graces mountain meadows throughout western North America. It flowers early in spring, when the first bumblebees and hummingbirds appear.
Or did.
The lily, a plant that grows best on subalpine slopes, is fast becoming a hothouse flower. In Earth’s warming temperatures, its first blooms appear some 17 days earlier than they did in the 1970s, scientists David Inouye and Amy McKinney of the University of Maryland and colleagues have found.

Innovative Model Aims to Export Solar Market Analysis Tools to the World
New York – 07 Jun 2012: IBM is helping New York City (NYC) become a global leader in urban solar energy market analysis and sustainability through an innovativeagreement with CUNY Ventures, a City University of New York (CUNY) Economic Development Corporation entity.
The goal of this effort is to nourish solar adoption by developing the capability to analyze and understand key solar market indicators that can make solar system development more cost competitive. Using IBM’s Intelligent Operations Center (IOC) for Smarter Cities as the backbone, this analytics-based approach will help New York City monitor and analyze solar production and capacity through a virtual control room that will provide a dashboard view of key indicators.
The collaboration is part of ‘Solar Market Analytics, Roadmapping, and Tracking NY’ (SMART NY), a groundbreaking project supported in part by the U.S. Department of Energy (DOE) ‘Rooftop Solar Challenge’, part of the DOE SunShot Initiative which is striving to make solar energy cost-competitive with other forms of energy by the end of the decade.

Scientists find key protein for algae growth in the ocean
Scientists have revealed a key cog in the biochemical machinery that allows marine algae at the base of the oceanic food chain to thrive. They have discovered a previously unknown protein in algae that grabs an essential but scarce nutrient out of seawater, vitamin B12.(more…)
Water is a natural element that provides life to all living things, from plants to animals and especially human beings. Thus, it is vital that water be consistently available for consumption. It does much more than quench your thirst. It is necessary to regulate body functions, and therefore keep you alive. (more…)
Cooking exhaust hoods designed for home kitchens vary widely in their ability to capture and vent away the air pollutants generated by the gas burners on cook stoves, according to a study by two Lawrence Berkeley National Laboratory (Berkeley Lab) scientists. Of seven representative devices they tested, the capture efficiency varied from less than 15 percent to more than 98 percent.
The study, by Woody Delp and Brett Singer of Berkeley Lab’s Environmental Energy Technologies Division, measured their pollutant capture efficiency, sound level generated by their fans, and airflow. Cooking exhaust hoods vent such pollutants as carbon monoxide, nitrogen oxides, formaldehyde, and fine particulates such as soot generated during cooking. (more…)
