Astrophysicists Identify the Habitable Regions of the Entire Universe

Slashdot - Mon, 2014-09-22 11:05
KentuckyFC writes It's not just star systems and galaxies that have habitable zones--regions where conditions are suitable for life to evolve. Astrophysicists have now identified the entire universe's habitable zones. Their approach starts by considering the radiation produced by gamma ray bursts in events such as the death of stars and the collisions between black holes and so on. Astrobiologists have long known that these events are capable of causing mass extinctions by stripping a planet of its ozone layer and exposing the surface to lethal levels of radiation. The likelihood of being hit depends on the density of stars, which is why the center of galaxies are thought to be inhospitable to life. The new work focuses on the threat galaxies pose to each other, which turns out to be considerable when they are densely packed together. Astronomers know that the distribution of galaxies is a kind of web-like structure with dense knots of them connected by filaments interspersed with voids where galaxies are rare. The team says that life-friendly galaxies are most likely to exist in the low density regions of the universe in the voids and filaments of the cosmic web. The Milky Way is in one of these low density regions with Andromeda too far away to pose any threat. But conditions might not be so life friendly in our nearest knot of galaxies called the Virgo supercluster."

Ask Slashdot: Who Should Pay Costs To Attend Conferences?

Slashdot - Mon, 2014-09-22 10:23
An anonymous reader writes I wanted to get your opinion on who should pay the costs associated with attending conferences. In the past, I've covered costs associated with attending some local (in town) conferences, but despite claims to be willing to cover some costs associated with conferences, training, and certifications, my requests have been denied. The short version is I would like to attend a national conference, hosted in Las Vegas, and that while specific to a technology, it is what 90% of my day is related to so its directly work related. My employer has declined to pay some of the costs associated with the conference, but has said if I pay my way, they will pay for the training associated with it. Since this is a pretty hot technology, I'm very interested in getting certified and appreciate their offer. I should add that I work for a public entity and due to some fairly public issues, we have enjoyed record levels of funding the past couple of years. We know that they cannot afford to continue so we're about to start a multi-year decrease in our budget. My current thoughts are: First, I was working for a company where we faced potential layoffs, getting as close as to within 24 hours of one. Even just having some job security is extremely appreciated. Second, I work in a WONDERFUL environment. They aren't clock punchers, its about getting the job done. We're not micromanaged and have freedom to try new things. For the public sector, I know those are rare things and I appreciate them. Third, I work on a very talented team. I am probably the weakest member, so for me its a perfect learning/growth opportunity. Finally, its not my employer saying the conference isn't important, its looking at the bottom line and that we are a public entity so its not like we can easily raise more money. Tough decisions must be made. For this particular conference, I decided to try and save up my own money. Unfortunately, my personal life has gotten in the way, so I've resorted to begging. My problem with this is I hate begging, but what am I going to do for future conferences? So should I re-think my acceptance of my employers policy and start looking for a new job? Obviously, it is a personal decision, but I don't have a mentor or close friends to act as sounding boards, so I'd love to hear your thoughts.

How Our Botched Understanding of "Science" Ruins Everything

Slashdot - Mon, 2014-09-22 09:42
An anonymous reader writes "Pascal-Emmanuel Gobry writes at The Week, "If you ask most people what science is, they will give you an answer that looks a lot like Aristotelian 'science' — i.e., the exact opposite of what modern science actually is. Capital-S Science is the pursuit of capital-T Truth. And science is something that cannot possibly be understood by mere mortals. It delivers wonders. It has high priests. It has an ideology that must be obeyed. This leads us astray. ... Countless academic disciplines have been wrecked by professors' urges to look 'more scientific' by, like a cargo cult, adopting the externals of Baconian science (math, impenetrable jargon, peer-reviewed journals) without the substance and hoping it will produce better knowledge. ... This is how you get people asserting that 'science' commands this or that public policy decision, even though with very few exceptions, almost none of the policy options we as a polity have have been tested through experiment (or can be). People think that a study that uses statistical wizardry to show correlations between two things is 'scientific' because it uses high school math and was done by someone in a university building, except that, correctly speaking, it is not. ... This is how you get the phenomenon ... thinking science has made God irrelevant, even though, by definition, religion concerns the ultimate causes of things and, again, by definition, science cannot tell you about them. ... It also means that for all our bleating about 'science' we live in an astonishingly unscientific and anti-scientific society. We have plenty of anti-science people, but most of our 'pro-science' people are really pro-magic (and therefore anti-science). "

Update: Mangalyaan's Main Engine Test Fired, Maven In Orbit

Slashdot - Mon, 2014-09-22 09:21
William Robinson writes Before the spacecraft is scheduled to enter Mars orbit, Indian Space Research Organization (Isro) scientists reignited the Mars Orbiter Mission spacecraft's main engine for four seconds as a trial. The liquid apogee motor (LAM) engine has been idle for about 300 days since the spacecraft left the Earth's orbit on a Martian trajectory on December 1, 2013. The short-duration test was to ensure that the engine is in good shape for the 24-minute crucial maneuver on Wednesday." In other Mars mission updates, NASA's Maven spacecraft arrived at Mars late Sunday after a 442 million-mile journey that began nearly a year ago.
