BP oil spill did $17.2 billion in damage to natural resources, scientists find

Thu, 20 Apr 2017 14:18:25 EDT ~ The 2010 BP Deepwater Horizon oil spill did $17.2 billion in damage to the natural resources in the Gulf of Mexico, a team of scientists recently found after a six-year study of the impact of the largest oil spill in US history. Find out more...

Chesapeake Bay pollution extends to early 19th century

Wed, 19 Apr 2017 17:04:02 EDT ~ Humans began measurably and negatively impacting water quality in the Chesapeake Bay in the first half of the 19th century, according to a study of eastern oysters. Find out more...

How campuses can measure their nitrogen footprints

Tue, 18 Apr 2017 16:18:58 EDT ~ A new groundbreaking initiative helps researchers to measure and reduce the nitrogen footprint left behind by campus activities like food waste and energy consumption. The publication outlines research aiming to reduce emissions of reactive nitrogen and prevent negative impacts on such things as water quality, air pollution, and climate change. Find out more...

Tracking down water pollution through DNA of algae

Tue, 18 Apr 2017 11:43:44 EDT ~ The degree of pollution of rivers resulting from human activities is assessed using different biotic indices. The latter reflect the ecological status of a river based on the quantity and diversity of organisms selected as bioindicators, due to their ecological preferences and tolerance to pollution. This is the case of diatoms, algae consisting of a single cell surrounded by a silica skeleton, recommended by researchers as one of the ideal bioindicators for rivers and lakes. Find out more...

Air pollution may directly cause those year-round runny noses, according to a mouse study

Tue, 18 Apr 2017 09:43:12 EDT ~ Although human population studies have linked air pollution to chronic inflammation of nasal and sinus tissues, direct biological and molecular evidence for cause and effect has been scant. Now, researchers report that experiments in mice continually exposed to dirty air have revealed that direct biological effect. Find out more...

'Bad' air may impact 'good' cholesterol increasing heart disease risk

Thu, 13 Apr 2017 16:10:48 EDT ~ Traffic-related air pollution may increase risk of developing cardiovascular diseases through its effects on high-density lipoprotein (HDL), also known as 'good' cholesterol. US middle-aged and older adults living in areas with high levels of traffic-related air pollution tended to have lower levels of good cholesterol. Changes in HDL levels were observed after brief and medium-length exposures to air pollution. Find out more...

Device pulls water from dry air, powered only by the sun

Thu, 13 Apr 2017 14:11:04 EDT ~ While it's easy to condense water from humid air, machines that harvest water from drier air require energy. Researchers have created the first water harvester that uses only ambient sunlight. The key component is an extremely porous material called a metal-organic framework that absorbs 20 percent of its weight in water from low-humidity air. Sunlight heats the MOF, releasing the water vapor, which condenses to produce liters of water per day. Find out more...

New breed of supermolecule 'hunts down' harmful drugs and removes them from water

Mon, 10 Apr 2017 19:41:47 EDT ~ Researchers have found an effective, environmentally friendly way to monitor and remove pharmaceuticals from water. Find out more...

Plants have been helping to offset climate change, but now it's up to us

Wed, 05 Apr 2017 13:10:12 EDT ~ Plants are currently removing more carbon dioxide from the air than they did 200 years ago, according to new work. This team's findings affirm estimates used in models from the Intergovernmental Panel on Climate Change. Find out more...
