Astronomers Measure the Elusive Extragalactic Background Light
by Perikis Livas in Tracing Knowledge
If all the light emitted by all galaxies in the observable universe at all wavelengths during all of cosmic history were known, it would clue astronomers about the entire history of galaxy formation and evolution, and provide insights to key aspects of the expansion history of the universe....

Intrinsic decoherence observed again!
by Marco Frasca in The Gauge Connection
Decoherence is the effect that causes a quantum system to behave classically. The most known of this kind of effects is due to environment where the interaction of an open quantum system with its surrounding is the reason for the loss of quantum coherence. This effect is well-proven on an experimental ground and must be considered […]... Read more »

Get the Science Right: Autism vs Vaccines Flares On
by Andrew Porterfield in United Academics
The reaction was swift, both times. In 1998, British scientist Andrew Wakefield published a paper in Lancet, showing that vaccines could result in autism. Alarmed parents looked at vaccines with suspicion—many kept their children from being vaccinated, which may have helped spark a measles outbreak or two. Then, in 2010, Lancet retracted the paper, and Wakefield eventually had his medical license revoked. But the controversy continues... Read more »

Accurate Distance Measurement Resolves Major Astronomical Mystery
by Perikis Livas in Tracing Knowledge
The researchers used the National Science Foundation’s Very Long Baseline Array (VLBA) and the European VLBI Network (EVN) to precisely locate one of the most-observed variable-star systems in the sky — a double-star system called SS Cygni — at 370 light-years from Earth. This new distance measurement meant that an explanation for the system’s regular outbursts that applies to similar pairs also applies to SS Cygni.... Read more »

‘Quantum microscope’ peers into the hydrogen atom
by Perikis Livas in Tracing Knowledge
The first direct observation of the orbital structure of an excited hydrogen atom has been made by an international team of researchers. The observation was made using a newly developed “quantum microscope”, which uses photoionization microscopy to visualize the structure directly. The team’s demonstration proves that “photoionization microscopy”, which was first proposed more than 30 years ago, can be experimentally realized and can serve as a tool to explore the s........
