Landslides are a striking example of erosion. When the bonds holding soil and rock particles together are overcome by a force — often in the form of water — sufficient to pull the rock and soil apart, that same force breaks the bonds with the other rock and soil holding them in place. Another type of erosion involves the use of small air jets to remove dust from the surface. When the turbulent forces of air are strong enough to break the bonds that hold individual dust particles, or grains, together and cause them to stick to the surface, that’s also erosion. In the pharmaceutical industry, cohesion/erosion dynamics are critical for successfully processing powders to make pharmaceuticals. They also play a key role in another, somewhat distant example: landing spacecraft on the surface, such as the moon. As the spacecraft descends, its engine exhaust causes granular material on the surface to be eroded and transported. The displaced material forms a crater, which must be the corre

Hotter temperatures and heavy rainfall coupled with climate change are perfect breeding grounds for the Aedes mosquito that spreads Dengue Fever. While many people enjoy warmer temperatures, basking in the sun, so do the Aedes mosquitoes which spread dengue fever. He well developed at temperatures ranging from 20 to 30 degrees Celsius. Higher temperatures mean increased rates of female Aedes mosquito bites, increasing the risk of disease transmission. The same higher temperatures accelerate the spread of mosquito-borne viruses. ADVERTISEMENT CONTINUE READING BELOW Both the increase in temperature and precipitation stemming from climate change will develop geographic distribution of dengue fever — increased temperatures shorten the mosquito breeding life cycle, and more rainfall provides mosquitoes with more places to breed and the humidity they need to thrive. Researchers in Malaysia now home mosquito trap trial to help solve the problem after other methods such as spraying bec

University of Chicago physicists have discovered a “quantum flute” that, like the Pied Piper, can force light particles to move together in a way never seen before. Described in two studies published in Physical Review Letters and Nature Physics, the breakthrough could point the way to the realization of quantum memory or new forms of error correction in quantum computers, and to observe quantum phenomena that cannot be seen in nature. Laboratory Association Prof. David Schuster is working on quantum bits – the quantum equivalent of computer bits – that take advantage of the peculiar properties of particles at the atomic and sub-atomic level to do things that would otherwise be impossible. In this experiment, they worked with light particles, known as photons, in the microwave spectrum. Their system consists of long cavities built into a metal block, designed to trap photons at microwave frequencies. Cavities are created by drilling offset holes — like holes in a flute. “Just like i

A new “quantum flute” experiment by University of Chicago physicists could point the way to new quantum technologies. The holes create different wavelengths, similar to the ‘notes’ on a flute, that can be used to encode quantum information.
