In 2014, a team of researchers led by a paleobiologist from the University of Missouri found that clams from the Holocene Epoch (that began 11,700 years ago) contained clues about how sea level rise due to climate change could foreshadow a rise in parasitic trematodes, or flatworms. The team cautioned that the rise could lead to outbreaks in human infections if left unchecked. Now, an international team from Mizzou and the Universities of Bologna and Florida has found that rising seas could be detrimental to human health on a much shorter time scale. Findings from their study in northern Italy suggest that parasitic infections could increase in the next century, if history repeats itself.

NASA Looks to Solar Eclipse to Help Understand Earth's Energy System
It was midafternoon, but it was dark in an area in Boulder, Colorado on Aug. 3, 1998. A thick cloud appeared overhead and dimmed the land below for more than 30 minutes. Well-calibrated radiometers showed that there were very low levels of light reaching the ground, sufficiently low that researchers decided to simulate this interesting event with computer models. Now in 2017, inspired by the event in Boulder, NASA scientists will explore the moon’s eclipse of the sun to learn more about Earth’s energy system.
On Aug. 21, 2017, scientists are looking to this year’s total solar eclipse passing across America to improve our modelling capabilities of Earth’s energy. Guoyong Wen, a NASA scientist working for Morgan State University in Baltimore, is leading a team to gather data from the ground and satellites before, during and after the eclipse so they can simulate this year’s eclipse using an advanced computer model, called a 3-D radiative transfer model. If successful, Wen and his team will help develop new calculations that improve our estimates of the amount of solar energy reaching the ground, and our understanding of one of the key players in regulating Earth’s energy system, clouds.
Berkeley Lab to Lead Multimillion-Dollar Geothermal Energy Project
The Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) will lead a new $9 million project aimed at removing technical barriers to commercialization of enhanced geothermal systems (EGS), a clean energy technology with the potential to power 100 million American homes.
Berkeley Lab will partner with seven other DOE national labs and six universities to develop field experiments focused on understanding and modeling rock fractures, an essential element of geothermal systems. Scientists will use the Sanford Underground Research Facility (SURF) in South Dakota to create small-scale fracture networks in crystalline rock 1,500 meters below ground.
Shale gas development spurring spread of invasive plants in Pa. forests
Vast swaths of Pennsylvania forests were clear-cut circa 1900 and regrowth has largely been from local native plant communities, but a team of researchers in Penn State's College of Agricultural Sciences has found that invasive, non-native plants are making significant inroads with unconventional natural gas development.
The spread of invasive non-native plants could have long-term negative consequences for the forest ecosystem in a region where the ubiquitous woods provide timbering revenue, wildlife habitat and ecotourism, warns team member David Mortensen, professor of weed and applied plant ecology.
Cash for carbon: A cost-effective way to reduce deforestation
A new Northwestern University study suggests that paying people to conserve their trees could be a highly cost-effective way to reduce deforestation and carbon emissions and should be a key part of the global strategy to fight climate change.
The study, led by Seema Jayachandran, associate professor of economics in the Weinberg College of Arts and Sciences at Northwestern, sought to evaluate how effective “Payments for Ecosystems” (PES) is at reducing deforestation. PES is a program in which people are given financial rewards for pro-environment behaviors.
Shading and Lighting Retrofits Slash Energy Use in New York ''Living Lab'' Office Demonstration
By using advanced lighting and automated shades, scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) found that occupants on one floor of a high-rise office building in New York City were able to reduce lighting energy usage by nearly 80 percent in some areas.
The dramatic results emerged at a “living laboratory” set up to test four sets of technologies on one 40,000 square-foot floor of a building.
