Gas turbine engines in planes provide the required thrust by sucking in air, heating it to very high temperatures in a combustion chamber, and finally exhausting it at high velocities. As they operate, small inorganic particles such as volcanic ash get sucked in along with the air. These particles melt in the high-temperature zones in the combustion chamber and solidify onto the cooler zones in...
Although educational outreach programs sometimes get short shrift in academic circles in terms of prioritizing, funding and staffing, a new Texas A&M University study indicates they are a solid investment with benefits far beyond the institutional bottom line when it comes to physics.
Nine out of 10 startups fail, and even among venture-backed fledgling companies, the success rate is only about 25%. It's even tougher for women entrepreneurs, who face challenges their male counterparts don't, according to new Cornell University research.
Where do our elements come from? And how are they made? Michael Famiano's new research is flipping the script on those age-old nuclear astrophysics questions. The truth is out there—several light years away among the stars, to be exact.
E-commerce shopping has risen sharply over the last decade, and most consumers are now reading product reviews prior to making their purchase decisions. Sites like Amazon use reviews to instill shopper confidence and boost product sales, and they often highlight specific reviews that are considered especially helpful. "Top reviews" and "helpful reviews" have become very popular labels on these...
With warming climate, summer sea ice in the Arctic has been shrinking fast, and now consistently spans less than half the area it did in the early 1980s. This raises the question: It this keeps up, in the future will year-round sea ice—and the creatures who need it to survive—persist anywhere?
An international team of physicists led by researchers at Indiana University Bloomington has announced the world's most precise measurement of the neutron's lifetime.
The interior of the Earth is a mystery, especially at greater depths (> 660 km). Researchers only have seismic tomographic images of this region and, to interpret them, they need to calculate seismic (acoustic) velocities in minerals at high pressures and temperatures. With those calculations, they can create 3D velocity maps and figure out the mineralogy and temperature of the observed regions....
