WASHINGTON, Nov. 17, 2011 -- The American Chemical Society (ACS), the world's largest scientific society, today released a series of audio podcasts highlighting the science and cutting-edge technology behind solar power. The podcasts, available without charge at http://www.acs.org/chemmatters, tell the story of how scientists and students are making progress in harnessing the abundant energy of the sun.

Extinct animals hide their secrets well, but an exceptionally well-preserved fossil of an aquatic reptile, with traces of soft tissue present, is providing scientists a new window into the behavior of these ancient swimmers.

CHAMPAIGN, Ill. — Emissions regulations do have an environmental impact, according to a long-term study of acidic rainfall by researchers at the University of Illinois.

The National Atmospheric Deposition Program collects rainfall samples weekly from more than 250 stations across the United States and analyzes them for pollutants. The program recently released a report detailing trends in acidic rainfall frequency and concentration over 25 years, from 1984 to 2009.

The birth of the Gamburtsev Subglacial Mountains buried beneath the vast East Antarctic Ice Sheet – a puzzle mystifying scientists since their first discovery in 1958 – is finally solved. The remarkably long geological history explains the formation of the mountain range in the least explored frontier on Earth and where the Antarctic Ice Sheet first formed. The findings are published this week in the journal Nature.

The impact of deforestation on global warming varies with latitude, according to new research from a team of scientists representing 20 institutions from around the world. The surprising finding, which researchers say calls for new climate-monitoring strategies, will be published in the Nov. 17 issue of the journal Nature.

In a significant finding in the search for life beyond Earth, scientists from The University of Texas at Austin and elsewhere have discovered what appears to be a body of liquid water the volume of the North American Great Lakes locked inside the icy shell of Jupiter's moon Europa.

The water could represent a potential habitat for life, and many more such lakes might exist throughout the shallow regions of Europa's shell, lead author Britney Schmidt, a postdoctoral fellow at The University of Texas at Austin's Institute for Geophysics, writes in the journal Nature.

New Haven, Conn.—Deforestation, considered by scientists to contribute significantly to global warming, has been shown by a Yale-led team to actually cool the local climate in northern latitudes, according to a paper published today in Nature.

DURHAM, New Hampshire, November 16, 2011 –A study that will be published in Nature on Thursday, Nov. 17, concludes that forests influence temperature, and their influence largely depends on latitude.

Palo Alto, CA—U.S. scientists have developed a new, integrated, ten-year science plan to better understand the details of Earth's carbon cycle and people's role in it. Understanding the carbon cycle is central for mitigating climate change and developing a sustainable future.

COPENHAGEN (16 November 2011) — In the lead up to UN global climate talks in Durban, South Africa later this month, an independent global commission of eminent scientists today released a set of concrete recommendations to policy makers on how to achieve food security in the face of climate change. Based on a thorough review of existing research, the commissioners urged immediate, coordinated action toward transforming the food system to meet current and future threats to food security and environmental sustainability.

In this week's PLoS Medicine, Shekhar Saxena of the WHO in Geneva, Switzerland and colleagues summarize the recent WHO Mental Health Gap Action Programme (mhGAP) intervention guide that provides evidence-based management recommendations for mental, neurological, and substance use (MNS) disorders. This guide is aimed at reducing the treatment gap for MNS disorders, which is more than 75% in many low- and middle-income countries (LMICs).

The first climate study to focus on variations in daily weather conditions has found that day-to-day weather has grown increasingly erratic and extreme, with significant fluctuations in sunshine and rainfall affecting more than a third of the planet.

Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons.

This while increasing rain, snowfall and the intensity of severe storms in wet regions or seasons, according to results of a new study.

The research provides the first clear evidence of how aerosols--soot, dust and other particulates in the atmosphere--may affect weather and climate.

University of California, Berkeley, scientists have shown that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial – able to kill bacteria – for as long as a week after treatment.

Devices able to produce such plasmas are cheap, which means they could be life-savers in developing countries, disaster areas or on the battlefield where sterile water for medical use – whether delivering babies or major surgery – is in short supply and expensive to produce.

The geological record holds clues that throughout Earth's 4.5-billion-year lifetime massive supervolcanoes, far larger than Mount St. Helens or Mount Pinatubo, have erupted. However, despite the claims of those who fear 2012, there's no evidence that such a supereruption is imminent.
