Phys.org / A hidden Oregon basin and a shallower slab sharpen the Cascadia megaquake threat

A new look at the Juan de Fuca tectonic plate beneath the coast of northern Oregon suggests this subducting slab is shallower than previously thought, with impacts on potential peak ground shaking during a Cascadia megathrust ...

Phys.org / Warm-bodied sharks and tunas face 'double jeopardy' in warming seas

A new study reveals that some of the ocean's most powerful predators are running hotter, and that they are likely paying an increasingly steep price for it. The significance of this headline finding is the "double jeopardy" ...

Medical Xpress / Fat cells steer flies away from pathogen-tainted food through a newly revealed neural circuit

If humans or animals eat something that causes them to feel unwell, they subsequently avoid this food source. Until now, it has been unclear precisely how this avoidance learning takes place. A new study shows that communication ...

Phys.org / Scientists unlock shape-shifting living tissue, programming cells to fold flat sheets into precise 3D forms

Biological tissues have a remarkable ability to organize and change shape, driven by forces generated by their own cells. One of the major challenges in bioengineering is harnessing this natural behavior to design synthetic ...

Phys.org / Deep earthquakes triggered by the olivine-poirierite transition

Seismicity decreases with depth because elevated confining pressure prevents frictional sliding of faults. However, seismicity tends to increase with depth in the mantle transition zone (depths of 410−600km). It has been ...

Medical Xpress / Chemical NDMA is much more likely to cause cancerous mutations after early-life exposure, study suggests

A new study from MIT suggests that a carcinogen that has been found in medications and in drinking water contaminated by chemical plants may have a much more severe impact on children than adults. In a study of mice, the ...
