Quasars are the light fantastic. They are the brightest beacons in the universe, blazing across space with the intrinsic brightness of one trillion suns. Yet the objects are not vast galaxies, but they appear as pinpoint sources in the biggest telescopes of today hence the term "quasar" for quasi-stellar object. Discovered in the 1960s, it took more than two decades of research to come to the conclusion that quasars are produced by the gusher of energy coming from over-fed supermassive black holes inside the cores of very distant galaxies. And, most quasars bloomed into a brief existence 12 billion years ago.
Flexible electronics have wide applicability, ranging from development of bendable screens to personal health monitors. Scientists are particularly interested in using these materials for medical applications; they've developed three-dimensional, flexible electronics that are compatible with the human body, and these show promise for integration into various tissues.
However, there are still significant limitations that must be addressed before these bioelectronics can be effectively used in a clinical setting. For example, it is very difficult to deliver soft bioelectronics to diseased regions in a patient-friendly manner. Recently, an international team of scientists demonstrated that flexible mesh electronics can be compacted and delivered using syringe injection.
After being manufactured, the mesh electronics are loaded into a needle that is inserted into an internal cavity, and the mesh is injected while the needle is withdrawn, placing the electronics in the targeted region. The mesh consists of longitudinal polymer/metal/polymer elements that interconnect electronics embedded in the polymer. The scientists found that the transverse and longitudinal stiffness of the material could be optimized to enable the mesh to “roll up” when passing through the needle.

This big, bright, beautiful spiral galaxy is Messier 64, often called the Black Eye Galaxy or the Sleeping Beauty Galaxy for its heavy-lidded appearance in telescopic views. M64 is about 17 million light-years distant in the otherwise well-groomed northern constellation Coma Berenices. In fact, the Red Eye Galaxy might also be an appropriate moniker in this colorful composition. The enormous dust clouds obscuring the near-side of M64's central region are laced with the telltale reddish glow of hydrogen associated with star forming regions. But they are not this galaxy's only peculiar feature. Observations show that M64 is actually composed of two concentric, counter-rotating systems. While all the stars in M64 rotate in the same direction as the interstellar gas in the galaxy's central region, gas in the outer regions, extending to about 40,000 light-years, rotates in the opposite direction. The dusty eye and bizarre rotation is likely the result of a billion year old merger of two different galaxies.
