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 / Cancer's hidden switch may sit in the cell membrane, forcing growth receptors into permanent overdrive
Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do more than simply provide ...
Phys.org / Extensive faults beneath Nevada nuclear lab raise unanswered earthquake risks
The underground laboratory in Nevada where the U.S. conducts nuclear subcritical experiments is riddled with faults. Researchers have not confirmed whether any of these faults are active and could rupture during an earthquake, ...
Phys.org / Gene discovery opens new path for disease-resistant rice breeding
Bacterial blight (BB) is a serious plant disease that mainly affects rice plants, especially in warm, humid regions. Due to the severity of BB, discovering and applying BB-resistance genes is strategically important for ensuring ...
Phys.org / Navigating the past with ancient stone compass needles
Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small samples of rocks, scientists can isolate magnetic grains that were frozen in orientation as the rock ...
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" ...
Phys.org / Novel technique drills more detail into ice core records
Glaciers can reveal vast archives of information about Earth's environmental past, but deciphering the origins of the matter within them can be a challenge. Now, using a novel technique that enables researchers to directly ...
Phys.org / Human sense of smell evolved with diets and lifestyle, genetic study suggests
From the ability to detect the smell of wet soil to the scent of ripe fruit, the human olfactory system has evolved over thousands of years in response to how people live and what they eat, according to a new genetic study ...
Phys.org / Industrial chemical leaks could push ozone layer recovery back by 7 years
The recovery of the ozone layer in Earth's stratosphere could be delayed by several years, according to an international study led by Swiss research institution Empa which included contributions from University of Bristol ...
Phys.org / Sex pheromone of a sandgrain-sized insect deciphered
Parasitic wasps of the genus Trichogramma are among the smallest insects in the world—yet they play an important role in natural ecosystems and agricultural landscapes as natural antagonists of pest species. Research teams ...
Phys.org / Closing the carbon cycle: Unraveling the roles of light and heat in CO₂ photocatalysis
Rising carbon dioxide (CO2) emissions from human activities are the largest contributor to global warming. According to the International Energy Agency (IEA), global CO2 emissions reached an all-time high of 37.8 gigatons ...
Phys.org / Temperature shifts change plant proteins that power photosynthesis
Humans adjust to changes in temperature by putting on a sweater or taking off layers. Plants adjust to temperature changes, in part, by switching the way they express the protein that performs the critical first step of photosynthesis, ...
