Shrinking Moon may be Generating Moonquakes

Evidence for moonquakes on Lee-Lincoln fault scarp
The Taurus-Littrow valley is the location of the Apollo 17 landing site (asterisk). Cutting across the valley, just above the landing site, is the Lee-Lincoln fault scarp. Movement on the fault was the likely source of numerous moonquakes that triggered events in the valley. 1) Large landslides on of slopes of South Massif draped relatively bright rocks and dust (regolith) on and over the Lee-Lincoln scarp. 2) Boulders rolled down the slopes of North Massif leaving tracks or narrow troughs in the regolith on the slopes of North Massif. 3) Landslides on southeastern slopes of the Sculptured Hills.

A new analysis suggests that the moon is actively shrinking and producing moonquakes along thousands of cliffs called thrust faults spr...

Plastic gets a do-over: Breakthrough Discovery Recycles Plastic from the Inside

Unlike conventional plastics, the monomers of PDK plastic could be recovered and freed from any compounded additives simply by dunking the material in a highly acidic solution. (Credit: Peter Christensen et al./Berkeley Lab)

Scientists have made a next-generation plastic that can be recycled again and again into new materials of any color, shape, or form. Because plastics contain various additives, like dyes, fillers, or flame retardants, very few plastics can be recycled without loss in performance or aesthetics. Even the most recyclable plastic, PET – or poly(ethylene terephthalate) – is only recycled at a rate of 20-30%, with the rest typically going to incinerators or landfills, where the carbon-rich material takes centuries to decompose.

Now a team of researchers at the U.S...

Engineers make Injectable Tissues a Reality

New device encases delicate cells into protective microgels. A simple injection that can help regrow damaged tissue has long been the dream of physicians and patients alike. A new study from researchers at UBC Okanagan moves that dream closer to reality with a device that makes encapsulating cells much faster, cheaper and more effective.

“The idea of injecting different kinds of tissue cells is not a new one,” says Keekyoung Kim, assistant professor of engineering at UBC Okanagan and study co-author. “It’s an enticing concept because by introducing cells into damaged tissue, we can supercharge the body’s own processes to regrow and repair an injury.”

Professor Thomas Gervais of Polytechnique Montréal and his students Pierre-Alexandre Goyette and Étienne Boulais, in partnership with the team led by Professor David Juncker of McGill University, have developed a new microfluidic process aimed at automating protein detection by antibodies. This work, the topic of an article in Nature Communications, points to the arrival of new portable instruments to accelerate the screening process and molecule analysis in biological laboratories to accelerate research in cancer biology.

Microfluidics refers to the manipulation of fluids in microscale devices...
