Applied Physics
Superconductivity was discovered in 1911 and has perplexed, astounded and inspired scientists since, but to most it can be thought of as "frictionless" electricity. In conventional electricity, heat is generated by friction as electrons (electric charge carriers) collide with atoms and impurities in the wire. This heating effect is good for appliances such as toasters or irons, but not so good for most other applications that use electricity.
In superconductors, however, electrons glide unimpeded between atoms without friction. If scientists and engineers ever harness this phenomenon at or…

Amyloid deposits in tissues and organs are linked to a number of diseases, including Alzheimer’s, Parkinson’s, type II diabetes, and prion diseases such as BSE. However, amyloids are not just pathological substances; they have potential as a nanomaterials.
Amyloid fibrils are bundles of highly ordered protein filaments made of ladder-like strands and can be several micrometers long.
In cross-section, amyloids appear as hollow cylinders or ribbons. Although amyloid fibrils are proteins, they more closely resemble synthetic polymers (plastics) than the usual globular proteins. Amyloids can…
As fossil fuel emissions continue to climb, reducing the amount of sunlight hitting the Earth would definitely have a cooling effect on surface temperatures.
The reduction in sunlight can be accomplished by geoengineering schemes. There are two classes: the so-called “sunshade” geoengineering scheme, which would mitigate climate change by intentionally manipulating the solar radiation on the earth's surface; the other category removes atmospheric CO2 and sequesters it into the terrestrial vegetation, oceans or deep geologic formations.
However, a new study from Lawrence Livermore National…

The best places to get accurate data about the world's ice shelves are not exactly the safest. Using satellites is not an accurate solution.
Researchers at the Georgia Institute of Technology and Pennsylvania State University have created specially designed robots called SnoMotes to traverse these potentially dangerous ice environments. The SnoMotes work as a team, autonomously collaborating among themselves to cover all the necessary ground to gather assigned scientific measurements. Data gathered by the Snomotes could give scientists a better understanding of the important dynamics that…
Scientists of the University of Almeria are developing a new system to eliminate carbon dioxide emissions using microalgae photosynthetic activity. This project, called CENIT CO2, is being developed by Spanish electricity company Endesa and is supported by the Spanish Ministry of Industry.
At the pilot plant, Las Palmerillas, Almeria-based researchers are trying to prove the validity of this new method for eliminating CO2 emissions. They expect to begin testing on an industrial level in the next year. Researchers say that ENDESA, which is promoting this research line, may test its…
