Resonance in Rainbow Bridge

Utah's iconic Rainbow Bridge hums with natural and human-made vibrations, according to a new study. The study characterizes the different ways the bridge vibrates and what frequencies and energy sources cause the rock structure to resonate. The vibrations are small, according to a geology and geophysics professor, but the study provides a baseline measure of the bridge's structural integrity and shows how human activities can rattle solid rock.

Fracking causes earthquakes, but new research finds way to make it safer

Injecting wastewater deep underground as a byproduct of oil and gas extraction techniques that include fracking causes human-made earthquakes, new research has found. The study, which also showed that the risk can be mitigated, has the potential to transform oil and gas industry practices.

Marriage made in sunlight: Invention merges solar with liquid battery

As solar cells produce a greater proportion of total electric power, a fundamental limitation remains: the dark of night when solar cells go to sleep. Lithium-ion batteries are too expensive a solution to use on something as massive as the electric grid. A professor of chemistry has a better idea: integrating the solar cell with a large-capacity battery.

Unique feeding habits of whales revealed

Whales are the biggest animals to ever have existed on Earth, and yet some subsist on creatures the size of a paper clip. It's a relatively common factoid, but, in truth, how they do this is only just being uncovered, thanks to new technologies.

Different tree species use the same genes to adapt to climate change, researchers find

Both pine and spruce use the same suite of 47 genes to adapt to geographic variation in temperature, and to appropriately time acquisition of cold hardiness -- a trait that allows plants to tolerate the adverse conditions of winter -- large-scale analysis has revealed.

Trophy hunting of lions can conserve the species, report suggests

Trophy hunters can play an important role in lion conservation, researchers have shown. These findings may surprise the public, but most lion conservationists think trophy hunting could play a key role in conserving this species because lions need large areas to thrive, and managing this land is expensive. The new work shows land under long-term management for trophy hunting can help fill this shortfall.

Iconic dinosaur shapes were present for at least a hundred million years on our planet in animals before those dinosaurs themselves actually appeared.

Peeling back the layers: Scientists use new techniques to uncover hidden secrets of plant...

Innovative new cell imaging techniques have now been pioneered to shed light on cells hidden deep inside the meristem. This new development has made it possible to explore further below the outer surface of plants and has uncovered how a key gene controls stem growth.

New model could point way to microbiome forecasting in the ocean

A new mathematical model integrates environmental and molecular sequence information to better explain how microbial networks drive nutrient and energy cycling in marine ecosystems.
