+ - Telescope captures a gravitational echo of the Big Bang

Submitted by bmahersciwriter
bmahersciwriter (2955569) writes "Detection of the elusive b-wave, announced today (, provides the firmest evidence yet of a round of exponential inflation in the universe in the first fractions of a second following the big bang. Einstein predicted the existence of these gravitational waves nearly a century ago ( but they've been extremely hard to detect. Now, a telescope in Antarctica called BICEP2 ( was able to pick up the signal by watching the cosmic microwave background, often considered the 'afterglow' of the Big Bang. It is considered a Nobel-worthy discovery."

It doesn't matter that the donor is dead. The process of cloning involves taking out DNA and inserting it into another cell. All that matters is that enough DNA can be collected for a complete organism. Freezing is completely irrelevant as even human embryos used for in-vitro fertilization are routinely frozen.

We have been able to clone several species already. That's not the problem. The problem is that you need a surrogate mother for the embryo and the closest we have is the African elephant, which separated from the mammoth a long time ago. From TFA it seems they are already working on cross-species clones but they are still a long way off.

CERN Wants a New Particle Collider Three Times Larger Than the LHC 238

Daniel_Stuckey writes "Not content with the 27-kilometer-round Large Hadron Collider, researchers at CERN have their sights set on a new beast of a particle collider that could have a circumference of 80 to 100 kilometers. The nuclear research organization announced that it was hatching plans for an ambitious successor to the LHC with an international study called the Future Circular Colliders program, which will kick off with a meeting next week. The idea is to consider different hadron collider designs similar to the existing LHC but more powerful — much more powerful. CERN wrote it was looking for a collider 'capable of reaching unprecedented energies in the region of 100 TeV.' The existing LHC will reach a maximum of around 14 TeV."

Spectacular New Martian Impact Crater Spotted From Orbit 99

New submitter kc123 writes: "The team that runs the HiRISE camera on the Mars Reconnaissance Orbiter has released a photo showning a new impact crater on Mars, formed sometime early this decade. The crater at the center is about 30 meters in diameter, and the material ejected during its formation extends out as far as 15 kilometers. The impact was originally spotted by the MRO's Context Camera, a wide-field imaging system that provides the context—an image of the surrounding terrain—for the high-resolution images taken by HiRISE. The time window on the impact, between July 2010 and May 2012, simply represents the time between two different Context Camera photos of the same location. Once the crater was spotted, it took until November of 2013 for another pass of the region, at which point HiRISE was able to image it." Reader astroengine adds some more Mars news: "On Thursday at 3:41 p.m. EST (20:41 UTC), Mars rover Curiosity beamed back a photo from its rear hazard avoidance camera (Hazcam). In the shot we see wheel tracks in the downward slope of the dune bridging "Dingo Gap" with the peak of Curiosity's eventual goal, Mount Sharp, on the horizon. This can mean only one thing; the one-ton robot has successfully conquered its first Mars dune! Curiosity has also taken a picture of Earth."
