And We're Back!

Well, hello readers!  This blog has been collecting dust for a while, during what I am going to call the Great Blog Hiatus of 2012.  But the dust is clearing and the Hiatus is ending.  The Meniscus is returning!  It’s been reworked a little bit, re-imagined slightly, and new posts will start appearing soon! 

So stay tuned, tell your friends, and get ready for science!

Like Reality, But Better

While browsing the technology news recently, I kept coming across the term “Augmented Reality (AR).”  Not being familiar with augmented reality, but being always curious, I decided to investigate exactly what it is.  As it turns out, it’s awesome, so I’m gonna blog about it.

I’m sure you’ve heard of virtual reality.  Virtual reality refers to computer-generated worlds or environments in which a user can explore and interact with virtual objects.  Of course, under that definition, pretty much any video game counts as a virtual reality, but the more popular, science-fiction concept of virtual reality is that of a person completely immersed in a simulated environment, interacting with computer-generated objects, like the holodeck on Star Trek, or the Danger Room of the X-Men, or the world of the Matrix (just to name a few fictional examples).  While modern VR technology isn’t nearly as advanced as it is in sci-fi, this technology is being used and experimented with these days not only for the obvious gaming applications, but for various sorts of military training, and medical applications.

Augmented reality is a little different.  Instead of creating virtual worlds, AR technology superimposes virtual data onto the real world, essentially enhancing the real world with computer-generated graphics.  This actually isn’t such a new or uncommon concept – if you have a smartphone, you have access to augmented reality technology.

Soundtrack of the Jurassic

Possibly the most amazing aspect of paleontology is not what we know about ancient life on Earth, but how we know what we do.  After all, most of what researchers have to work with is simply bones or impressions of bodies in the dirt; how much could we possibly be able to tell about the life of an ancient organism?  Well, the most challenging – and rewarding – part of a paleontologist’s job is finding ways to use the limited material they have to go beyond simple anatomy and make exciting inferences about prehistoric life: bite marks on fossil bone can tell us about predator-prey interactions; footprints can give us an idea of how ancient animals moved; I’ve posted before (twice actually) about how recent discoveries have actually allowed us to infer the color of ancient creatures.  Well, a new study based on an exceptional fossil katydid – yes, bugs can be fossils too! – is now not only filling out our picture of what the age of the dinosaurs looked like, but also giving us insight into what it sounded like.

Mars Science Lab: Liftoff!

Yesterday morning, at 10:02 EST, NASA’s Mars Science Laboratory (MSL) took off from Cape Canaveral in Florida.  In my opinion, this is possibly the most exciting scientific event of the year, as this mission to Mars is carrying the new Mars rover, Curiosity.

Curiosity isn’t the first Mars rover, of course.  The first was the small rover Pathfinder, which spent nearly three months on Mars in 1997 and set the precedent for all following rovers.   Most people are probably more familiar with the Mars Exploration Rovers (MER), Spirit and Opportunity.  The MER twins landed on opposite sides of Mars in 2004, their mission to answer the big question: has there ever been permanent water on Mars?  In the time since their deployment, these rovers, along with the handful of other landers and orbiters we’ve sent to Mars, have uncovered astounding evidence of past Martian environments: geologic features that hint at ancient river beds, floods, and perhaps even oceans.  The resounding answer is yes, Mars used to have plenty of water.

And why do we care if Mars had water?  Because on Earth, water is the basis of all life.  If Mars had water at one point, could it also have had life like we have on Earth?  This is the underlying question in all Mars research, and it is the main objective of the Mars Science Laboratory mission.

Flashback

With each new blog post, I try to find some big important new research to talk about, and I try to vary the topics as much as I can.  But just because I posted about something already doesn’t mean that research has stopped, and every now and then I find some new developments in news I've already blogged about.  Here are some recent updates to previous topics I've mentioned:
