| Black hole at the center of our galaxy appears to be getting hungrier Posted: 11 Sep 2019 01:52 PM PDT The enormous black hole at the center of our galaxy is having an unusually large meal, and researchers don't know why. 'We have never seen anything like this in the 24 years we have studied the supermassive black hole,' said a professor of physics and astronomy. |
| Nerve-like 'optical lace' gives robots a human touch Posted: 11 Sep 2019 12:12 PM PDT A new synthetic material that creates a linked sensory network similar to a biological nervous system could enable soft robots to sense how they interact with their environment and adjust their actions accordingly. |
| Towering balloon-like features discovered near center of Milky Way Posted: 11 Sep 2019 11:28 AM PDT Astronomers have discovered one of the largest features ever observed in the center of the Milky Way: a pair of enormous radio-emitting bubbles that tower hundreds of light-years above and below the central region of our galaxy. |
| New metamaterial morphs into new shapes, taking on new properties Posted: 11 Sep 2019 11:27 AM PDT Electrochemical reactions drive shape change in new nanoarchitected metamaterial. |
| Milestones on the way to the nuclear clock Posted: 11 Sep 2019 11:27 AM PDT For decades, people have been searching for suitable atomic nuclei for building an ultra-precise nuclear clock. For a long time it had been conjectured that a specific thorium isotope must have a nuclear state that would be suitable for this purpose. This long-sought core state of thorium has now been demonstrated experimentally for the first time -- twice, by 2 different international research teams. |
| Reconstructing the evolution of all species Posted: 11 Sep 2019 11:27 AM PDT By looking into fossil teeth from almost 2 million years old rhinos, researchers have launched a new molecular method for studying the evolutionary history of fossil species dating back millions of years. |
| 'Flying fish' robot can propel itself out of water and glide through the air Posted: 11 Sep 2019 11:27 AM PDT A bio-inspired bot uses water from the environment to create a gas and launch itself from the water's surface. |
| Solving the longstanding mystery of how friction leads to static electricity Posted: 11 Sep 2019 09:19 AM PDT Scientists developed a new model, which shows that rubbing two objects together produces static electricity, or triboelectricity, by bending the tiny protrusions on the surface of materials. |
| Water detected on an exoplanet located in its star's habitable zone Posted: 11 Sep 2019 09:19 AM PDT Astronomers have detected water vapor on the exoplanet K2-18b -- a major discovery in the search of alien life. |
| Scientists detect the ringing of a newborn black hole for the first time Posted: 11 Sep 2019 09:19 AM PDT Physicists have 'heard' the ringing of an infant black hole for the first time, and found that the pattern of this ringing does, in fact, predict the black hole's mass and spin -- more evidence that Einstein was right all along. |
| Chameleon inspires 'smart skin' that changes color in the sun Posted: 11 Sep 2019 05:38 AM PDT Chemists used photonic crystals to develop a flexible smart skin that reacts to heat and sunlight while maintaining a near constant volume. |
| Can a DNA construction kit replace expensive antibody medication? Posted: 11 Sep 2019 04:42 AM PDT Researchers have developed a technique to make sheep produce new antibodies simply by injecting the DNA building blocks. The study in animals with a similar size as humans brings us a step closer to the clinical use of antibody gene therapy. |
