Chemist focuses on education for real-world sustainability challenges

Introductory college science classes need to improve their coverage of issues related to sustainability, a noted chemistry educator told the American Association for the Advancement of Science. \”Across the nation, we have a problem,\” said Catherine Middlecamp, a distinguished faculty associate in chemistry at the University of Wisconsin-Madison. \”We are using a 20th-century curriculum, and […] … learn more→

Global Emission Trends

Global carbon emissions to double in 20 years The recently published Global Emissions Trends analysis projects that in a \”business as usual\” scenario (i.e. no changes to carbon emission policies) global carbon emissions will double by 2030. … learn more→

Sustainable projects showcased in unique engineering event

A wind-powered turbine, water filter research, a rainwater harvesting project and a newly built pedal-power cinema were showcased at the University of Sheffield as part of a unique event designed to show how engineers can have a positive influence on the world. The Engineers Without Borders (EWB) Sheffield Showcase demonstrated the exciting sustainable development projects […] … learn more→

The Green machine: Algae clean wastewater, convert to Biodiesel

Let algae do the dirty work. Researchers at Rochester Institute of Technology are developing biodiesel from microalgae grown in wastewater. The project is doubly “green” because algae consume nitrates and phosphates and reduce bacteria and toxins in the water. The end result: clean wastewater and stock for a promising biofuel. The purified wastewater can be […] … learn more→

World\’s first skyscraper was a monument to intimidation

Discovered by archaeologists in 1952, a 28-foot-high stone tower discovered on the edge of the town of Jericho has puzzled scientists ever since. Now, eleven millennia after it was built, Tel Aviv University archaeologists at the ancient site Tel Jericho are revealing new facts about the world\’s first skyscraper.\” Recent computer-based research by doctoral student […] … learn more→

Biological anthropologists question claims for human ancestry

\”Too simple\” and \”not so fast\” suggest biological anthropologists from the George Washington University and New York University about the origins of human ancestry. In the upcoming issue of the journal Nature, the anthropologists question the claims that several prominent fossil discoveries made in the last decade are our human ancestors. Instead, the authors offer […] … learn more→

Global warming may reroute evolution

Rising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the University of Michigan suggests. The research focused on the effects of elevated carbon dioxide on common milkweed, Asclepias syriaca. Milkweed is one of many plants that produce […] … learn more→

Thawing permafrost likely will accelerate global warming in coming decades, says study

Up to two-thirds of Earth\’s permafrost likely will disappear by 2200 as a result of warming temperatures, unleashing vast quantities of carbon into the atmosphere, says a new study by the University of Colorado Boulder\’s Cooperative Institute for Research in Environmental Sciences. The carbon resides in permanently frozen ground that is beginning to thaw in […] … learn more→
