  • Researchers have developed a new way of growing realistic human tissues outside the body. Their 'person-on-a-chip' technology, called AngioChip, is a powerful platform for discovering and testing new drugs, and could eventually be used to repair or replace damaged organs.
  • Scientists have long been puzzled by Mercury's very dark surface. Previously, scientists proposed that the darkness came from carbon accumulated by comet impacts. Now scientists confirm that carbon is present at Mercury's surface, but that it most likely originated deep below the surface, in the form of a now-disrupted and buried ancient graphite-rich crust, which was later brought to the surface via impacts after most of the current crust formed.
  • The universe is constantly expanding. But how does our universe evolve? Physicists have now developed a new code of numerical simulations that offers a glimpse of the complex process of the formation of structures in the universe. Based on Einstein's equations, they were able to integrate the rotation of space-time into their calculations and calculate the amplitude of gravitational waves.
  • A web-based machine language system solves crossword puzzles far better than commercially-available products, and may help machines better understand language.
  • Engineers have developed a 'meta-skin' that uses liquid-metal technology to trap radar waves and cloak objects from detection. By stretching the flexible meta-skin, the device can be tuned to reduce the reflection of a wide range of radar frequencies.
