SALEM – A public partnership with the Oregon Department of Energy, Oregon Department of Land Conservation & Development, Oregon State University’s Institute for Natural Resources, and the U.S. Department of Defense has published new educational materials that will help local governments, Tribes, communities, policymakers, agencies, energy developers, and other stakeholders access important information and considerations for potential renewable energy in Oregon.

The Oregon Renewable Energy Siting Assessment (ORESA) project was funded through a $1.1 million U.S. Department of Defense (DoD) grant, with the goal of providing baseline data to support important conversations around potential energy and transmission development in the state.

German energy firm RWE is to invest in a pilot project centered around the deployment of floating solar technology in the North Sea, as part of a wider collaboration focused on the development of “floating solar parks.”

Set to be installed in waters off Ostend, Belgium, the pilot, called Merganser, will have a capacity of 0.5 megawatt peak, or MWp. In a statement earlier this week, RWE said Merganser would be Dutch-Norwegian firm SolarDuck’s first offshore pilot.

RWE said Merganser would provide both itself and SolarDuck with “important first-hand experience in one of the most challenging offshore environments in the world.”

Silicon is one of the most abundant elements on Earth, and in its pure form the material has become the foundation of much of modern technology, from solar cells to computer chips. But silicon’s properties as a semiconductor are far from ideal.

For one thing, although silicon lets electrons whizz through its structure easily, it is much less accommodating to “holes”—electrons’ positively charged counterparts—and harnessing both is important for some kinds of chips. What’s more, silicon is not very good at conducting heat, which is why overheating issues and expensive cooling systems are common in computers.

Now, a team of researchers at MIT, the University of Houston, and other institutions has carried out experiments showing that a material known as cubic arsenide overcomes both of these limitations. It provides to both electrons and holes, and has excellent thermal conductivity. It is, the researchers say, the best semiconductor material ever found, and maybe the best possible one.

Carbon labelling gives consumers a weapon to fight climate change at the cash register.

What’s Involved with Carbon Labelling

Today, nutritional and content labelling can be found on packaged foods. The Government recently announced plans to enhance those labels. Why, because of concerns that Canadians need to learn more about what they eat so that they can make healthier choices.

Carbon labelling would serve a similar purpose by allowing Canadians to make healthier choices about carbon emissions. A carbon label would let consumers understand the environmental impact of items they purchase and consume. The label would contain the total carbon footprint of the product.

Scientists studying the aging process in the eye have made an important discovery around the role of a so-called “youth” protein, and shown how it promotes a cellular recycling process that maintains our vision. Experiments on mice missing this protein led to fast-tracked degeneration in the retina, indicating that the protein plays an important protective role against age-related vision loss.

Led by scientists at the US National Eye Institute, the study centers on a protein called pigment epithelium-derived factor (PEDF). This protein plays an important mediatory role in a natural recycling process in the eye. It is produced by a layer of support cells, called the retinal pigment epithelium (RPE), which sits beneath the retina’s light-sensing photoreceptor cells and helps recycle and replenish them as their outer edges wear out. This ability declines as we grow older and in people with age-related macular degeneration (AMD), leading to vision loss.

“People have called PEDF the ‘youth’ protein, because it is abundant in young retinas, but it declines during aging,” said Patricia Becerra, senior author of the study. “This study showed for the first time that just removing PEDF leads to a host of gene changes that mimic aging in the retina.”
