10 miles across explosion brighter the Milky Way
2016/1/22
Right now, astronomers are viewing a ball of hot gas billions of light years away that is radiating the energy of hundreds of billions of suns. At its heart is an object a little larger than 10 miles ...

A brighter design emerges for low-cost, 'greener' LED light bulbs（图）
greener LED light bulbs
2014/12/1
The phase-out of traditional incandescent bulbs in the U.S. and elsewhere, as well as a growing interest in energy efficiency, has given LED lighting a sales boost. However, that trend could be short-...
Researchers from North Carolina State University have developed a new processing technique that makes light emitting diodes (LEDs) brighter and more resilient by coating the semiconductor material gal...
Among the taxidermal specimens in Harvard’s Museum of Comparative Zoology, past centuries-old fur coats, arises a flicker of brilliant blue. This is the spangled cotinga. Surprisingly, the cotinga is ...
When Keynes wrote his famous essay, times were tough and a dim future loomed. But Keynes warned his readers not to confuse the short run with the long run, and reassured them that the long term fundam...
A group of leading Australian scientists has come together to develop lower-cost flexible optoelectronic solutions that could transform the Australian consumer electronics industry.
New Physics with MeV Neutrino Sources Brighter than a Thousand Suns
New Physics MeV Neutrino Sources Brighter a Thousand Suns
2010/12/27
Short baseline oscillations of neutrinos (nue and nuebar) due to active-sterile (a-s) mixing can be observed explicitly using MeV neutrino beams and existing/planned neutrino detectors. The typical ba...

Short baseline oscillations of neutrinos (νe and ṽe) due to active-sterile (a-s) mixing can be observed explicitly using MeV ν beams and existing/planned ν detectors.
Anti-mirror effect: A perfect lens brings a brighter feature
Anti-mirror effect perfect lens brighter feature
2010/11/12
In this letter, we show that a perfect lens can be employed to make multiple objects appear like only one in the far field, leading to a new concept of illusion optics. Numerical simulations are perf...
