| Making computers reason and learn by analogy Posted: 21 Jun 2016 12:50 PM PDT Using the power of analogy, a new structure-mapping engine gives computers the ability to reason like humans and even solve moral dilemmas. |
| Astronomers find the first 'wind nebula' around a magnetar Posted: 21 Jun 2016 12:49 PM PDT Astronomers have discovered a vast cloud of high-energy particles called a wind nebula around a rare ultra-magnetic neutron star, or magnetar, for the first time. The find offers a unique window into the properties, environment and outburst history of magnetars, which are the strongest magnets in the universe. |
| Present-day subsurface ocean on Pluto? Posted: 21 Jun 2016 10:25 AM PDT An updated thermal model for Pluto suggests that a liquid water ocean beneath the dwarf planet's ice shell is a fairly likely scenario, and that the ocean is probably still there today. |
| An ocean lies a few kilometers beneath Saturn's moon Enceladus's icy surface Posted: 21 Jun 2016 08:57 AM PDT With eruptions of ice and water vapor, and an ocean covered by an ice shell, Saturn's moon Enceladus is one of the most fascinating in the Solar System, especially as interpretations of data provided by the Cassini spacecraft have been contradictory until now. Astronomers recently proposed a new model that reconciles different data sets and shows that the ice shell at Enceladus's south pole may be only a few kilometers thick. This suggests that there is a strong heat source in the interior of Enceladus, an additional factor supporting the possible emergence of life in its ocean. |
| Caribbean Sea acts like a whistle and can be 'heard' from space Posted: 21 Jun 2016 08:15 AM PDT A study of the Caribbean Sea has revealed that, in the midst of all the noise of the ocean, this region behaves like a whistle, which blows so loudly that it can be 'heard' from space in the form of oscillations of the Earth's gravity field. |
| Massive vertebrae sheds new light on Alamosaurus sanjuanensis Posted: 21 Jun 2016 08:11 AM PDT The discovery nearly two decades ago of nine beautifully articulated vertebrae at Big Bend National Park sheds new light on a 66 million-year-old sauropod dinosaur native to Texas and the North American southwest called Alamosaurus sanjuanensis. |
| Understanding rogue ocean waves may be simple after all Posted: 21 Jun 2016 06:10 AM PDT An international team of scientists has developed a relatively simple mathematical explanation for the rogue ocean waves that can develop seemingly out of nowhere to sink ships and overwhelm oil platforms with walls of water as much as 25 meters high. |
| Posted: 20 Jun 2016 04:14 PM PDT Researchers have designed and produced a self-assembling protein shell shaped like an icosahedron -- similar to those that encapsulate viruses. The achievement may open new avenues for engineering cargo-containing nano-cages to package and deliver drugs and vaccines directly into cells, or building small reactors to catalyze biochemical reactions. The shell is also amenable to genetic fusion, such as the addition of fluorescent proteins. |
