Posted September 27, 2011 This is really awesome. Preserved dinosaur feathers in amber http://www.newsvine.com/_news/2011/09/15/7...osaur-diversity More and more proof that (some of) our birds are just tiny flying (or non-flying in the case of chickens) dinosaurs! Who can prove the 90-million-year-old feathers are from dinosaurs and not archaeopteryx? Oh, wait, archaeopteryx was already extinct by then... /shot What I'm trying to say, though, remains: The feathers could have been from a number of early birds that came way after the famous species cited above.

Posted September 27, 2011 Not really. There's other evidence of feathers on certain dinosaurs and they can date the amber back to around when those dinosaurs were around. Speaking of unbelievable things, they discovered a particle (or at least clocked a particle) that moves faster than light. http://www.nytimes.com/2011/09/23/science/23speed.html Although they are still doing tons of testing on it because it's such a huge discovery. They don't want to discredit the last hundred years of physics just yet. Share this post Link to post

This is quite possibly one of the most exciting things I've ever seen -saw it a few days ago- Just... if it's real, we have faster than light travel. Even if it's at such a small scale, it's still just completely incredible. Share this post Link to post

Posted September 27, 2011 (edited) I'm still having a hard time acknowledging that Pluto isn't a planet. LIES. If time travel turns out to be possible, I'm guessing that several people from the forums will be making DIY TARDISes. Edited September 27, 2011 by RheaZen Share this post Link to post

An amazing series, even for those like me who have no real passion for dinosaurs but remember thinking how cool they were as kids. Share this post Link to post

They don't want to discredit the last hundred years of physics just yet. I know that there is evidence of feathers on dinosaurs, but the feathers in the amber are not necessarily from a dinosaur: The feathers found in amber are between 70 anmd 90 million years old. Feathered birds existed more than 150 million years ago, and so did feathered dinosaurs (probably, I don't know the actual numbers for feathered dinosaurs). From that evidence, you cannot know whether the feathers are from birds or dinosaurs without further testing. That's all I'm saying. Just looking at feathers preserved in amber and claiming they have to be from a dinosaur is not very convincing. Share this post Link to post
Posted September 29, 2011 "Today a group of paleontologists announced the results of an extensive study of several well-preserved dinosaur feathers encased in amber." http://io9.com/5840854/dinosaur-feathers-d...-canadian-amber Perhaps you misunderstood? This is something they have in fact been researching, not just looking at. You don't make a major announcement like that without any kind of research. It's not like they discovered the amber that very day. Most "discoveries" they announce have been sitting in a basement of a museum for years before getting cataloged. Share this post Link to post
Posted September 30, 2011 From the very same article: They can't determine which feathers belonged to birds or dinosaurs yet, but they did observe filament structures that are similar to those seen in other non-avian dinosaur fossils. And: "We don't absolutely know what they are, but we're pretty sure what they're not," he notes. They could be protofeathers, McKellar says. (What they're not: plant fiber or fungal threads.) So, no, I don't think I misunderstood. Share this post Link to post
Posted October 1, 2011 Here are some interesting articles on Neanderthal/human breedings that were supplementary reading for a homework assignment I had in my BIO 350 genetics course: http://www.nytimes.com/2010/05/07/science/07neanderthal.html http://www.sciencenews.org/view/generic/id...ing_with_humans Also, something else I didn't know until I took this course, regarding neanderthals and red hair: http://www.sciencedaily.com/releases/2007/...71025143311.htm I love the aspect of biology that deals with human evolution/evolution in general. I'm planning on taking an upper level biology course on evolution specifically next semester. Hopefully my professor will hook me up with some cool papers regarding evolution.

Posted November 29, 2011 A science joke/riddle thing I'm just going to dump here: A guy walks into a bar and asks "I'll have some H2O" Another guy walks into the bar and asks "I'll have some H2O too" The second guy died. Why? (Answer in white below) H2O2 (H2 O too) is Hydrogen peroxide, which is poisonous if swallowed Also scientists apparently found a particle faster than the speed of light. Lost the link, sorry.
