C2ST Artist in Residence Aaron Freeman pretends to interview Stanford University Neurobiology professor Robert Sapolsky on the difference between the brains of Chicago Cubs fans and those of lesser beings. According to Sapolsky part of the difference may have to do with higher sustained levels of the neurotransmitter dopamine.
Clarity, specificity and humor are among the best tools for making kids grasp even simple questions like “What is a flame?” Science correspondent Miles O’Brien talks to actor Alan Alda and scientist Neil deGrasse Tyson about the need to explain science concepts to the public.
Microsoft’s Research arm has given the world a sneak peek at its latest project: 3D-scanning using a regular mobile phone.
Through a new blog post and video, the team explained that the project will allow anybody to create high-quality 3D images in real time. Microsoft has basically figured out a way to turn the average smartphone’s rear camera into a 3D scanner – no additional hardware required.
Here’s everything we know about the project so far…
What is MobileFusion?
MobileFusion is the name of Microsoft Research’s 3D-scanning project.
What’s the point of MobileFusion?
With MobileFusion, you’ll be able to create 3D models while on the go. You’ll have the ability to grab your iPhone, for instance, then point the phone’s rearcamera at an object, and scan said object by moving your iPhone around it.
MobileFusion essentially compares RGB data within all the frames shot from different angles in order to build up a model in real time. All the work is done on the phone and doesn’t require extra hardware or even an internet connection, meaning you could be deep in the woods and still manage to capture a 3D model of like a rock or something using just a regular smartphone without a Wi-Fi connection.
What can you do with a 3D model made from MobileFusion?
Microsoft Research said MobileFusion 3D scans are “high-quality enough to be used for things like 3D printing and augmented reality video games” – but if you watch the demo below, you’ll see the scans are still rough at this point.
Epigenetic changes often serve to biologically prepare offspring for an environment similar to that of the parents, Yehuda explains. In this case, however, the needs of the fetus seem to have trumped that goal. With low levels of cortisol and high levels of the enzyme that breaks it down, many descendants of Holocaust survivors would be ill adapted to survive starvation themselves. In fact, that stress hormone profile might make them more susceptible to PTSD (below, yellow); previous studies have indeed suggested that the offspring of Holocaust survivors are more vulnerable to the effects of stress and are more likely to experience symptoms of PTSD. These descendants may also be at risk for age-related metabolic syndromes, including obesity, hypertension and insulin resistance, particularly in an environment of plenty.
They’re less likely to trip because they shorten their step length, reduce step frequency, lengthen the time during which both feet are in contact with the ground, and increase obstacle clearance height. Taken together this creates an exaggerated image of walking, but it apparently slows the walker enough so that he registers some of what is happening around him and can compensate for it.
The impact of texting and walking is that it slows the walker down. So we’re all connected but it may take us longer to get to each other–which may be okay since we’ve likely texted the person that we’re on our way and then given a play-by-play of our progress as we update social media along the way.
“Subject-specific lessons – an hour of history in the morning, an hour of geography in the afternoon – are already being phased out for 16-year-olds in the city’s upper schools. They are being replaced by what the Finns call “phenomenon” teaching – or teaching by topic. For instance, a teenager studying a vocational course might take “cafeteria services” lessons, which would include elements of maths, languages (to help serve foreign customers), writing skills and .”
