Berkeley Researchers Design Artificial Photosynthetic System Using Sequestrated Carbon Dioxide

A research team from the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley has developed a hybrid system of bacteria and semiconducting nanowires, which imitate the natural process of photosynthesis by which plants use solar energy for carbohydrate synthesis from water and carbon dioxide.

Ozone Air Pollution Could Affect Women’s Ability to Conceive

Many urban and suburban areas have high levels of ground-level ozone, an air pollutant that can adversely affect lung and heart health. New research in mice suggests that breathing high levels of ozone could also affect women’s ability to conceive.

Researchers Discover Switch That Regulates Plant Photosynthesis, Could Boost Biofuel Production

A team of Michigan State University researchers has discovered a switch that regulates plant photosynthesis – the process that lets plants store solar energy and use it to grow and produce food.

Armadas of Icebergs May Not Be the Cause of Cooling in the North Atlantic

Armadas of icebergs were probably not the cause of abrupt episodes of cooling in the North Atlantic over the past 440,000 years, according to new research published today in Nature.

Nontoxic, Potentially Recyclable Reservoir Stimulation Fluid for Cleaner Geothermal Energy

More American homes could be powered by the earth's natural underground heat with a new, nontoxic and potentially recyclable liquid that is expected to use half as much water as other fluids used to tap into otherwise unreachable geothermal hot spots.

New Way to Make Bio-Based Plastics Using Plant Oils

Researchers have developed a new way to use plant oils like olive and linseed oil to create polyurethane, a plastic material used in everything from foam insulation panels to tires, hoses and sealants.

Researcher Develops Models of Marine Microbes to Understand Global Climate Change

Dip a beaker into any portion of the world’s oceans, and you’re likely to pull up a swirling mix of planktonic inhabitants. The oceans are teeming with more than 5,000 species of phytoplankton — microscopic plants in a kaleidoscope of shapes and sizes. Together, phytoplankton anchor the ocean’s food chain, supplying nutrients to everything from single-celled organisms on up to fish and whales.

Full Absorption Concept Design for Efficient Electromagnetic Energy Harvesting

For our modern, technologically-advanced society, in which technology has become the solution to a myriad of challenges, energy is critical not only for growth but also, more importantly, survival. The sun is an abundant and practically infinite source of energy, so researchers around the world are racing to create novel approaches to "harvest" clean energy from the sun or transfer that energy to other sources.

Rapid Climate Change Affected Marine Ecosystems Tens of Thousands of Years Ago

In common parlance, the phrase "global climate change" is often used to describe how present-day climate is changing in response to human activities. But climate has also varied naturally and sometimes quite rapidly in the past, with implications for the ocean and its ecosystems.

Deep Borehole Concept Holds Promise for Disposing High Level Nuclear Waste

Scientists at the University of Sheffield calculate that all of the UK's high level nuclear waste from spent fuel reprocessing could be disposed of in just six boreholes 5km deep, fitting within a site no larger than a football pitch.

BPA Can Alter Turtle's Reproductive System

Bisphenol A (BPA) is a chemical that is used in a variety of consumer products, such as food storage products and resins that line plastic food and beverage containers. Often, aquatic environments such as rivers and streams become reservoirs for BPA, and fish and turtle habitats are affected. Now, a collaboration of researchers from the University of Missouri, Westminster College, the U.S. Geological Survey and the Saint Louis Zoo have determined that BPA--which mimics estrogen--can alter a turtle's reproductive system and disrupts sexual differentiation. Scientists are concerned findings could indicate harmful effects on environmental and human health.

Insecticides Pose Alarming Threats to Biodiversity of Global Agricultural Surface Waters

A study performed at the Institute for Environmental Science of the University of Koblenz-Landau evaluated for the first time comprehensive global insecticide contamination data for agricultural surface waters using the legally-accepted regulatory threshold levels (RTLs) as defined during the official pesticide authorisation procedures.
