Dinosaurs Done In By... Dark Matter? 135

Posted by Unknown Lamer from the mysterious-forces dept.
bmahersciwriter writes "Theoretical physicists propose that the Sun periodically crosses into a dense layer of dark matter sandwiching the Milky Way. The gravitational push and pull that this creates disturbs debris in the Oort cloud sending deadly comets and asteroids ricocheting around the solar system. This passage happens, their admittedly speculative model suggests, every 35 million years, which jibes somewhat with evidence on impact craters. Take it with a dino-sized grain of salt."

Ask Slashdot: How Do I Change Tech Careers At 30? 451

Posted by timothy from the question-is-will-you-trust-yourself-next-year? dept.
First time accepted submitter possiblybored writes "I'm 30, and I am a technology teacher and the school's technology coordinator. I like my job, but I have been having thoughts about switching careers and focusing more on technology in the private sector. I like Microsoft products and would head in that direction, probably. Is it too late for me to think about this? What is the best way to get started on this path? I'm not so much interested in programming (though I'd like to learn a language some day) as much as I am intrigued by topics like setting up e-mail servers, reading about cloud stuff like Office 365, and looking at information on collaborative technology. I'm a good teacher and excel at explaining things as well. Any advice the community could offer would be greatly appreciated!"

Low-Protein Diet May Extend Lifespan 459

Posted by Soulskill from the suddenly-i-feel-much-healthier dept.
sciencehabit writes "A new theory about the foods that can extend life is taking shape, and it's sure to be a controversial one. Two studies out this week, one in mice (PDF) and another primarily in people (PDF), suggest that eating relatively little protein and lots of carbohydrates — the opposite of what's urged by many human diet plans, including the popular Atkins Diet — extends life and fortifies health."
