  Houston TX (SPX) Aug 27, 2018 First, according to Rice University engineers, get a nanotube hole. Then insert water. If the nanotube is just the right width, the water molecules will align into a square rod. Rice materials scientist Rouzbeh Shahsavari and his team used molecular models to demonstrate their theory that weak van der Waals forces between the inner surface of the nanotube and the water molecules are strong enough to snap the oxygen and hydrogen atoms into place. Shahsavari referred to the contents as two-dim ... read more |

 Washington (AFP) Aug 28, 2018  President Donald Trump stepped up attacks on big tech firms Tuesday, warning Facebook, Google and Twitter to be "careful," hours after slamming what he called "rigged" internet search results.
Trump offered no details on what if any actions he might take, but a top White House aide suggested the administration may look at some type of regulation in response to the president's complaints.

 Nuremberg, Germany (SPX) Aug 27, 2018 
In the 1940s, scientists first explained how materials can deform plastically by atomic-scale line defects called dislocations. These defects can be understood as tiny carpet folds that can move one part of a material relative to the other without spending a lot of energy.
Many technical applications are based on this fundamental process, such as forging, but we also rely on the power of d ... more |

 Cambridge UK (The Conversation) Aug 30, 2018 
Philosophers have debated the nature of "nothing" for thousands of years, but what has modern science got to say about it? In an interview with The Conversation, Martin Rees, Astronomer Royal and Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge, explains that when physicists talk about nothing, they mean empty space (vacuum).
This may sound straightforward, b ... more |
