Hidden Dangers in the Air We Breathe

Berkeley Lab researchers work on new building standards after discovering previously unknown indoor air pollutants.

For decades, no one worried much about the air quality inside people’s homes unless there was secondhand smoke or radon present. Then scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) made the discovery that the aggregate health consequences of poor indoor air quality are as significant as those from all traffic accidents or infectious diseases in the United States. One major source of indoor pollutants in the home is cooking.

The Berkeley Lab scientists are now working on turning those research findings into science-based solutions, including better standards for residential buildings and easier ways to test for the hazardous pollutants. These efforts are the result of a paper published in Environmental Health Perspectives in 2012 that described a new method for estimating the chronic health impact of indoor air pollutants. That research uncovered two pollutants that previously had not been recognized as a cause for concern—fine particles and a gas called acrolein. (more…)

NASA’s HyspIRI Sees the Forest for the Trees and More

To Robert Green, light contains more than meets the eye: it contains fingerprints of materials that can be detected by sensors that capture the unique set of reflected wavelengths. Scientists have used the technique, called imaging spectroscopy, to learn about water on the moon, minerals on Mars and the composition of exoplanets. Green’s favorite place to apply the technique, however, is right here on the chemically rich Earth, which is just what he and colleagues achieved this spring during NASA’s Hyperspectral Infrared Imager (HyspIRI) airborne campaign.

“We have ideas about what makes up Earth’s ecosystems and how they function,” said Green, of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., who is principal investigator of the campaign’s Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) instrument. “But a comprehensive understanding requires us to directly measure these things and how they change over landscapes and from season to season.” (more…)

Proximity to Coal-Tar-Sealed Pavement Raises Risk of Cancer, Study Finds

People living near asphalt pavement sealed with coal tar have an elevated risk of cancer, according to a study in the journal Environmental Science and Technology. Much of this calculated excess risk results from exposures in children, age six or younger, to polycyclic aromatic hydrocarbons (PAHs) from the sealant.

“The increased cancer risk associated with coal-tar-sealed asphalt (CSA) likely affects a large number of people in the U.S. Our results indicate that the presence of coal-tar-based pavement sealants is associated with significant increases in estimated excess lifetime cancer risk for nearby residents,” said E. Spencer Williams, Ph.D., principal author of the study and Baylor University assistant research scientist at the Center for Reservoir and Aquatic Systems Research in Baylor’s College of Arts & Sciences.

IBM Taps Big Data to Help Solve Water Challenges Across South Africa

“WaterWatchers,” a new mobile app, harnesses the power of crowdsourcing

Johannesburg, South Africa – 22 Mar 2013: IBM marks World Water Day with the launch of a crowdsoucing project to help capture, share and analyze information about the water distribution system in South Africa. The project, called “WaterWatchers,” is driven by a new mobile phone application and SMS capability that will enable South African citizens to report water leaks, faulty water pipes and general conditions of water canals. Every update will provide vital data points to an aggregated “WaterWatchers” report to create a single view of the issues challenging South Africa’s water distribution system.

The free app, which is currently available for Android and available for download at www.ibmwaterwatchers.co.za, and the SMS capability* together provide an easy way for anyone to collect and report issues on local waterways and pipes to a centralized portal. After taking a photo and answering three simple questions about the particular water canal or pipe, the data is uploaded in real-time to a central database. After 30 days, the data will be analyzed and aggregated into a meaningful “leak hot spot” map for South Africa. (more…)

Under California: An ancient tectonic plate

The Isabella anomaly — indications of a large mass of cool, dehydrated material about 100 kilometers beneath central California — is in fact a surviving slab of the Farallon oceanic plate. Most of the Farallon plate was driven deep into the Earth’s mantle as the Pacific and North American plates began converging about 100 million years ago, eventually coming together to form the San Andreas fault.

PROVIDENCE, R.I. [Brown University] — Large chunks of an ancient tectonic plate that slid under North America millions of years ago are still present under parts of central California and Mexico, according to new research led by Brown University geophysicists. (more…)

Study Finds Severe Climate Jeopardizing Amazon Forest

PASADENA, Calif. – An area of the Amazon rainforest twice the size of California continues to suffer from the effects of a megadrought that began in 2005, finds a new NASA-led study. These results, together with observed recurrences of droughts every few years and associated damage to the forests in southern and western Amazonia in the past decade, suggest these rainforests may be showing the first signs of potential large-scale degradation due to climate change.

An international research team led by Sassan Saatchi of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., analyzed more than a decade of satellite microwave radar data collected between 2000 and 2009 over Amazonia. The observations included measurements of rainfall from NASA’s Tropical Rainfall Measuring Mission and measurements of the moisture content and structure of the forest canopy (top layer) from the Seawinds scatterometer on NASA’s QuikScat spacecraft.

PASADENA, Calif. — The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest known spiral, based on archival data from NASA’s Galaxy Evolution Explorer (GALEX) mission, which has since been loaned to the California Institute of Technology in Pasadena.

Measuring tip-to-tip across its two outsized spiral arms, NGC 6872 spans more than 522,000 light-years, making it more than five times the size of our Milky Way galaxy. (more…)
