The report, in Genome Announcements, comes after almost seven years of research, according to Dr. Tim Devarenne, AgriLife Research biochemist and principal investigator in College Station. In addition to sequencing the genome, other genetic facts emerged that ultimately could help his team and others studying this green microalga further research toward producing algae and plants as a renewable fuel source.

"This alga is colony-forming, which means that a lot of individual cells grow to form a colony. These cells make lots of hydrocarbons and then export them into an extracellular matrix for storage," Devarenne said. "And these hydrocarbons can be converted into fuels -- gasoline, kerosene and diesel, for example, the same way that one converts petroleum into these fuels."

The same technology that adds fizz to soda can now be used to remove particles from dirty water. Researchers at Princeton University have found a technique for using carbon dioxide in a low-cost water treatment system that eliminates the need for costly and complex filters.

The system injects CO2 gas into a stream of water as a method of filtering out particles. The gas, which mixes with the water in a system of channels, temporarily changes the water's chemistry. The chemical changes cause the contaminating particles to move to one side of the channel depending on their electrical charge. By taking advantage of this migration, the researchers are able to split the water stream and filter out suspended particles. 

When asked why she loves to garden, Shirley Ross quotes the late Lois Hole, Alberta’s most beloved green thumb.

"Caring is the soul of gardening . . . We take risks and place our trust in factors beyond our control. Yet in the end, we are almost always rewarded with a beautiful harvest."

Identifying areas of particular high impact is an important step to improving the environmental sustainability of production systems. Insects have been heralded as the foods of the future - and now the first study to measure the environmental impacts and identify hotspots associated with commercial insect production has been published.

Cricket farming can be a sustainable way to produce animal source foods

The study demonstrated that cricket farming can be a sustainable means of producing animal source foods. The study compared cricket production in Thailand to broiler chicken production. Fifteen different environmental impacts were investigated including global warming potential, resource depletion and eutrophication. In most cases, cricket production had a lower impact than broiler chicken production. The major reason for the lower impacts is the fact that the feed conversion into animal protein is more efficient, as the production of the feed is a major hotspot in both systems.

Neonicotinoid pesticides hinder wild queen bumblebees’ reproductive success, according to a new University of Guelph study.

The study is the first to link exposure to thiamethoxam — one of the most commonly used neonicotinoid pesticides — to fewer fully developed eggs in queens from four wild bumblebee species that forage in farmland.

A WSU research team for the first time has developed a promising way to recycle the popular carbon fiber plastics that are used in everything from modern airplanes and sporting goods to the wind energy industry.

The work, reported in Polymer Degradation and Stability, provides an efficient way to re-use the expensive carbon fiber and other materials that make up the composites.

Researchers from the University of Antwerp and KU Leuven have succeeded in developing a process that purifies air and, at the same time, generates power. The device must only be exposed to light in order to function.

The U.S. wind energy industry experienced its fastest first-quarter growth since 2009, installing 2,000 new megawatts of capacity — enough to power about 500,000 homes — on its way to producing 5.5 percent of the country’s electricity.

The American Wind Energy Association (AWEA) also reported that another 21,000 megawatts of wind energy capacity is now under construction or in advanced development — enough to power an additional 5 million average U.S. homes. The AWEA said that 908 utility-scale wind turbines were erected in the first quarter of 2017, driving a nearly four-fold increase in wind energy growth over the first quarter of 2016. Forty-one U.S. states — most recently Rhode Island and North Carolina — now have utility-scale wind power projects. Texas is by far the wind energy leader in the U.S., with a wind power capacity of 21,000 megawatts.

By 2050, we will need to feed 2 billion more people on less land. Meanwhile, carbon dioxide levels are predicted to hit 600 parts per million—a 50% increase over today’s levels—and 2050 temperatures are expected to frequently match the top 5% hottest days from 1950-1979. In a three-year field study, researchers proved engineered soybeans yield more than conventional soybeans in 2050’s predicted climatic conditions.

As electronics become increasingly pervasive in our lives – from smart phones to wearable sensors – so too does the ever rising amount of electronic waste they create. A United Nations Environment Program report found that almost 50 million tons of electronic waste were thrown out in 2017—more than 20 percent higher than waste in 2015. Troubled by this mounting waste, Stanford engineer Zhenan Bao and her team are rethinking electronics. “In my group, we have been trying to mimic the function of human skin to think about how to develop future electronic devices,” Bao said. She described how skin is stretchable, self-healable and also biodegradable – an attractive list of characteristics for electronics. “We have achieved the first two [flexible and self-healing], so the biodegradability was something we wanted to tackle.”
