Bloomberg Report Suggests Comcast & Time Warner Merger Dead

Slashdot - Thu, 23/04/2015 - 7:58pm
andyring writes: According to Bloomberg News, the Time Warner/Comcast merger of raw evil is dead. Comcast plans as early as tomorrow to withdraw the merger proposal, "after regulators decided that the deal wouldn't help consumers, making approval unlikely" according to the story. If so, that means regulators won't have the chance to kill it themselves.

Virtual Telescope Readied To Image Black Hole's 'Ring of Fire'

Slashdot - Thu, 23/04/2015 - 7:05pm
astroengine writes: With the addition of a telescope at the southern-most point of Earth, the Event Horizon Telescope (EHT) now spans the diameter of our planet and, when the vast project goes online, astronomers will get their first glimpse of the bright ring surrounding a supermassive black hole. Using a method known as Very Long Baseline Interferometry, or VLBI, astronomers can combine the observing power of many telescopes situated at distant locations around the planet. The distance between those observatories, known as the "baseline," then mimics a virtual telescope of that diameter. Now, in an attempt to make direct observations of the supermassive black hole in the center of our galaxy, located at a powerful radio emission source called Sagittarius A*, the South Pole Telescope (SPT) at the National Science Foundation's Amundsen-Scott South Pole Station has been linked to the EHT and the stage is set for a historic new era of exploring the most extreme objects in the known universe. "Now that we've done VLBI with the SPT, the Event Horizon Telescope really does span the whole Earth, from the Submillimeter Telescope on Mount Graham in Arizona, to California, Hawaii, Chile, Mexico, Spain and the South Pole," said Dan Marrone of the University of Arizona. "The baselines to SPT give us two to three times more resolution than our past arrays, which is absolutely crucial to the goals of the EHT. To verify the existence of an event horizon, the 'edge' of a black hole, and more generally to test Einstein's theory of general relativity, we need a very detailed picture of a black hole. With the full EHT, we should be able to do this."

Revolutionary discovery leads to invention of new 'building blocks'

Science Daily - Thu, 23/04/2015 - 6:28pm
Taking a revolutionary 'building blocks' approach, a research team has invented a new thinking pathway in the design and synthesis of macromolecules by creating an original class of giant tetrahedra. Through a reaction called 'click chemistry,' these tetrahedron building blocks can then be precisely manipulated to unite with other tetrahedrons.

Photosynthesis has unique isotopic signature: 'Clumped' isotopes used to trace biogeochemical processes

Science Daily - Thu, 23/04/2015 - 6:28pm
Photosynthesis leaves behind a unique calling card, a chemical signature that is spelled out with stable oxygen isotopes, according to a new study. The findings suggest isotopic signatures could exist for many biological and geological processes, including some that are difficult to observe with current tools.

A GPS for chromosomes: Microtubules direct chromosomes during cell division

Science Daily - Thu, 23/04/2015 - 6:27pm
Scientists have identified a " Highway Code" within cells, a finding that changes the way we perceive how chromosomes move during cell division. Using chromosomes as a model to explain this navigation system, the research team show how this signaling mechanism determines the path through which molecular transporters travel. They have revealed that the existence of specific signals on microtubules -- which work as intracellular highways -- give directions to chromosomes on which route to take in the course of cell division.
