Better bacteria-busting techniques could make oil extraction greener, cheaper

Simple tweaks to oilfield practice could provide the offshore industry with a more sustainable, money-saving solution to health and safety, environmental and commercial threats posed by harmful bacteria in subsea oil deposits.

Marine incentives programs may replace ‘doom and gloom’ with hope

Incentives that are designed to enable smarter use of the ocean while also protecting marine ecosystems can and do work, and offer significant hope to help address the multiple environmental threats facing the world’s oceans, researchers conclude in a new analysis.

Bees can do basic arithmetic

Researchers set out to test whether bees could do math, building on a groundbreaking finding that bees understand the concept of zero. The new study shows bees can be taught to recognize colors as symbolic representations for addition and subtraction, and use this information to solve arithmetic problems. The revelation that even the miniature brain of a honeybee can grasp basic mathematical operations has implications for the future development of AI.

Climate predictions should include impacts of CO2 on life

Climate change predictions are not taking account of the full range of possible effects of rising carbon dioxide levels, researchers say.

Research for an oil (palm) change

A new technique shows great promise for helping oil palm growers optimize production and reduce environmental impacts. The research focused on crop yield, nitrous oxide emissions and nitrogen leaching.

Forces that threaten sensitive coastlines

Wind-driven expansion of marsh ponds on the Mississippi River Delta is a significant factor in the loss of crucial land in the Delta region, according to new research. The study found that 17 percent of land loss in the area resulted from pond expansion, much of it caused by waves that eroded away the edges of the pond.

Phosphorus nutrition can hasten plant and microbe growth in arid, high elevation sites

Glacial retreat in cold, high-altitude ecosystems exposes environments that are extremely sensitive to phosphorus input, new research shows. The finding upends previous ecological assumptions, helps scientists understand plant and microbe responses to climate change and could expand scientists' understanding of the limits to life on Earth.

Scientists identify a new approach to recycle greenhouse gas

Using a novel approach involving a key enzyme that helps regulate global nitrogen, molecular biologists have discovered an effective way to convert carbon dioxide to carbon monoxide that can be adapted for commercial applications like biofuel synthesis.

Dengue virus infection may cause severe outcomes following Zika virus infection during pregnancy

Prior Dengue virus infection may cause severe outcomes following Zika virus infection during pregnancy, a new study shows. The research points to a possible mechanism for the enhancement of Zika virus progression during pregnancy in an animal model.

Acidity in atmosphere minimized to preindustrial levels

New research shows that human pollution of the atmosphere with acid is now almost back to the level that it was before the pollution started with industrialization in the 1930s. The results come from studies of the Greenland ice sheet.
