Italian astronomers have conducted multi-band observations of the high-redshift blazar S5 0836+710 during its period of high activity. The monitoring campaign resulted in the detection of two major gamma-ray flares from this ...
A team of Empa acoustic researchers has built macroscopic crystal structures that use internal rotation to attenuate the propagation of waves. The method makes it possible to build very light and stiff materials that can ...
The iconic appearance of a spiral galaxy is exemplified here in the form of the stunning NGC 2903, imaged by the NASA/ESA Hubble Space Telescope. It shows off whirling, pinwheeling arms with scatterings of sparkling stars, ...
Spears and poisoned blowguns at hand, the Waorani people say they are ready to strike down invaders of their Amazon homelands, just like their forefathers did.
Gravitational echoes may be caused by the collision of two black holes, and may indicate that these objects have completely new physical properties. This conclusion was made by RUDN physicists after a series of mathematical ...
Astronomers are poised Wednesday to unveil the first direct image of a black hole and the surrounding whirlwind of white-hot gas and plasma inexorably drawn by gravity into its ravenous maw, along with the light they generate.
New photonic tools for medical imaging can be used to understand the nonlinear behavior of laser light in human blood for theranostic applications. When light enters biological fluids it is quickly scattered, however, some ...
In the blink of an eye, squid can change from sandy brown to vibrant red or ripple with bright metallic rainbows. Their color-changing abilities (and those of their fellow cephalopods, octopus and cuttlefish) are more sophisticated ...
The Cigar Galaxy (also known as M82) is famous for its extraordinary speed in making new stars, with stars being born 10 times faster than in the Milky Way. Now, data from the Stratospheric Observatory for Infrared Astronomy, ...
Physicists at the National Institute of Standards and Technology (NIST) have "flash-frozen" a flat crystal of 150 beryllium ions (electrically charged atoms), opening new possibilities for simulating magnetism at the quantum ...
