Google is making good on its promise to make its Maps app more comprehensive and useful following its acquisition of mapping company Waze, with some new traffic update features going live Tuesday.


Users of the Maps app on Android- and iOS-based devices will have access to real-time incident reports from Waze users, Google Maps vice president Brian McClendon said in a Tuesday blog post. That means that when people report accidents, construction, road closures and more on Waze, those updates will also appear within the Google Maps app in Argentina, Brazil, Chile, Colombia, Ecuador, France, Germany, Mexico, Panama, Peru, Switzerland, the U.K. and the U.S., Google said.


The integration between the two products is significant, said John Jackson, an industry analyst with IDC. While the new features for Google Maps probably will not attract new users in droves, they represent Google's attempts to add richness to its mapping products and provide more context to users, he said.

How To Become A Learning Teacher - Edudemic

How To Become A Learning Teacher - Edudemic | Technology |

For learning teachers, it isn’t just about coming to work and teaching your students each day. Its about continuing to challenge yourself and continuing to learn throughout your career.

Every teacher should be asking themselves these questions. The focus always must be on better learning for students.

Easy visuals to share. Could do a whole pro d on this topic.

Real-Time MRI Helps Neurosurgeons During Surgeries

Real-Time MRI Helps Neurosurgeons During Surgeries | Technology |

A new system for visualizing the brain during surgery is helping neurosurgeons more accurately diagnose and treat patients and is even allowing them to perform some procedures that until now have been extremely difficult or even impossible.


Neurosurgeons can use the imaging technology during surgeries that require small objects—biopsy needles, implants, or tubes to deliver drugs—to be placed at precise locations in the brain. The system provides live magnetic resonance images (MRI) that allow surgeons to monitor their progress during the operation.  


Typically, neurosurgeons use an MRI before a surgery to plan the trajectory of the operation, based on the brain’s position relative to a guidance frame that’s screwed onto the patient’s skull, says Robert Gross, a neurosurgeon at Emory University. But the brain can shift before the actual surgery takes place, he says, rendering that MRI inaccurate. To check on what’s happening inside a patient’s skull, doctors have to stop the surgery and perhaps even move the patient out of the operating room.


To address these issues, researchers have been developing new neurosurgical guidance systems that can work with the strong magnets and electronic signals used by MRI scanners. The medical-device company Medtronic, for example, offers a real-time MRI imaging system for neurosurgery. But Gross says the most useful system on the market is offered by MRI Interventions, a medical device company based in Memphis, Tennessee.


The MRI Interventions system works with conventional MRI scanners. A platform for guiding surgical tools or implants into the brain is affixed to the skull and provides a grid-based system for determining the trajectory. A material in the platform makes the device visible to the MRI scanner. Software from MRI Interventions shows surgeons where their tools are relative to the patient’s brain. That data is displayed on an MRI-compatible monitor to allow surgeons a view of what is happening inside the patient’s skull without interfering with the imaging procedure, which is a problem associated with most electronic equipment.
