How to see the Geminid meteor shower

Geminids are the most underappreciated annual event of the astronomical calendar. They occur in mid-December when it’s often too cold and cloudy in the Northern Hemisphere to really appreciate them. And it’s a shame since the Geminids are almost always…

Fukushima: Lessons learned from an extraordinary case of soil decontamination

(European Geosciences Union) Following the accident at the Fukushima nuclear power plant in March 2011, the Japanese authorities decided to carry out major decontamination works in the affected area, which covers more than 9,000 km2. On Dec. 12, 2019, with most of this work having been completed, the scientific journal SOIL of the European Geosciences Union (EGU) is publishing a synthesis of approximately 60 scientific publications that provide an overview of the decontamination strategies used and their effectiveness.

Researchers perfect nanoscience tool for studies of nuclear waste storage

(University of Guelph) Studying radiation chemistry and electronic structure of materials at scales smaller than nanometres, the University of Guelph team prepared samples of clay in ultra-thin layers. Working at the TRIUMF particle accelerator, they bombarded the samples with antimatter subatomic particles. They found their system is a proven tool for radiation studies of material to be used to store nuclear waste — important for Canadian nuclear industry looking to build its first geological repository.

Novel e-skin achieves self-powered hippocampal neural stimulation

(Chinese Academy of Sciences Headquarters) Chinese scientists recently developed a flexible electronic skin (e-skin) capable of self-powered neural stimulation and inducing a neural response. The technology will be useful in characterizing synaptic plasticity.

Martian aurora offers climate change clues, Embry-Riddle reports

(Embry-Riddle Aeronautical University) A newly published study reveals that a type of Martian aurora originally detected by NASA’s MAVEN spacecraft is in fact the most common aurora on the Red Planet, Embry-Riddle Aeronautical University researchers said. The research suggests a way to track water loss and better understand how the Martian climate has changed over time.

Supporting structures of wind turbines contribute to wind farm blockage effect

(American Institute of Physics) Much about the aerodynamic effects of larger wind farms remains poorly understood. New work in this week’s Journal of Renewable and Sustainably Energy looks to provide more insight in how the structures necessary for wind farms affect air flow. Using a two-scale coupled momentum balance method, researchers theoretically and computationally reconstructed conditions that large wind farms might face in the future, including the dampening effect that comes with spacing turbines close to one another.

Canadian tundra formerly covered in rich forest: Ancient plant fossil record shows

(University of Saskatchewan) Canada’s northernmost islands, Ellesmere and Axel Heiberg islands in Nunavut, were home to a vibrant, temperate forest 56 million years ago, according to fossil research just published by University of Saskatchewan (USask) scientists.

Monster 75-foot wave loomed off the California coast during the holiday weekend

The California coast is known for some monster waves, but over the Thanksgiving holiday, there was one mountainous undulation the likes of which few have ever matched. A shocking reading by a Scripps Institution of Oceanography Coastal Data Information Program…

How to recycle your Christmas lights

It doesn’t feel right to put Christmas lights in a trash can. Maybe they’ve stopped working, or maybe you’re replacing incandescent lights with safer, more energy-efficient LEDs. In any case, after brightening so many holiday seasons over the years, it…

Thunderquakes make underground fiber optic telecommunications cables hum

Telecommunications lines designed for carrying internet and phone service can pick up the rumble of thunder underground, potentially providing scientists with a new way of detecting environmental hazards and imaging deep inside the Earth.
