Until we recognize the essential role of biology, our attempts to truly unify the universe will remain a train to nowhere. ~Robert Lanza Read More
Good health is not something we can buy. However, it can be an extremely valuable savings account. ~Anne Wilson Schaef Read More
The only way forward, if we are going to improve the quality of the environment, is to get everybody involved. ~Richard Rogers Read More
To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science. ~Albert Einstein Read More
Old Newtonian physics claimed that things have an objective reality separate from our perception of them. Quantum physics, and particularly Heisenberg's Uncertainty Principle, reveal that, as our perception of an object changes, the object itself literally changes. ~Marianne Williamson Read More

A new pencil-like wireless spectrometer can be used with a smartphone to collect 3-D spectral images of the body and other objects. This design could make the device useful for point-of-care diagnostics. Credit: Dan Wang, Beijing University of Chemical Technology
Easy-to-use spectrometer less than $300, holds promise for remote medical diagnostics. A new smartphone-compatible device that is held like a pencil could make it practical to acquire spectral images of everyday objects and may eventually be used for point-of-care medical diagnosis in remote locations. Spectral images, which contain more color information than is obtainable with a typical camera, reveal characteristics of tissue and other biological samples that can’t be seen by the naked eye...

Supernova discovery challenges known theories of the death of stars. An international team of astronomers led by Las Cumbres Observatory (LCO) has made a bizarre discovery; a star that refuses to stop shining. Supernovae, the explosions of stars, have been observed in the thousands and in all cases they marked the death of a star. But a remarkable exception is a star that exploded multiple times over a period of more than 50 years. Their observations, which include data from Keck Observatory on Maunakea, Hawaii, are challenging existing theories on these cosmic catastrophes.
“The spectra we obtained at Keck Observatory showed that this supernova looked like nothing we had ever seen before...

Multi-wavelength image helping astronomers decipher complex collision history. A giant collision of several galaxy clusters, each containing hundreds of galaxies, has produced this spectacular panorama of shocks and energy. The collisions generated shock waves that set off a celestial fireworks display of bright radio emission, seen as red and orange. In the center of the image, the purple indicates Xrays caused by extreme heating.
The region is collectively known as Abell 2744, some 4 billion light-years from Earth...
