The study is part of a small body of research investigating how nutrition can improve brain health and stave off the cognitive decline and memory impairment that comes with Alzheimer’s disease and other forms of dementia. Experts…

Employees, Measure Yourselves
Encouraging workers to keep track of what they’re doing can make them healthier and more productive
- By H. JAMES WILSON
Imagine how much better workers could do their jobs if they knew exactly how they spend their day.
Suppose they could get a breakdown of how much time they spend actually working on…

MOOCs are inspiring university and high school teachers to try assigning video lectures for homework so class time can be used for asking questions and hands-on assignments.
When the first Massive Open Online Course (MOOC) enrolled over a hundred thousand students from all over the world, it started an education buzz about how technology could revolutionize higher education.
A few years later, MOOCs haven’t exactly replaced expensive college degrees, but edX CEO Anant Agarwal says the MIT experiment with MOOCs has given educators important insights into how students learn.
In his TED talk, Agarwal describes how MOOCs are inspiring university and high school teachers to try assigning video lectures for homework so class time can be used for asking questions and hands-on assignments.
He’s fired up at how engaged students have been and at the power of immediate feedback the online platform offers. Even more impressive, students from around the world are discussing concepts together online, eventually finding answers to questions on their own.
MOOCs may not have upended the university system as predicted, but they may have done something better, Agarwal says — force inert institutions to rethink their practices.
“We have invented bioconcrete — that’s concrete that heals itself using bacteria,” professor Henk Jonkers from TU Delft told CNN.
After nine years of research and development, a team from TU Delft presented their self-healing concrete prototype that regenerates itself due to the addition of bacteria in its composition. These bacteria have the ability to “break” some specific components in the concrete and gradually fix small cracks and holes.
The formula developed at the university goes beyond merely repairing visible imperfections; If not repaired, these cracks can increase in size and allow water to enter the structure, leading to the corrosion of steel and damaging the mechanical properties of the structure.
This kind of bioconcrete incorporates some species of bacillus bacteria, that can survive up to five decades without food or oxygen. In order to last so long, the bacillus bacteria are stored within the concrete in biodegradable plastic capsules that only break open when they come into contact with water. After being exposed to water, the bacteria feeds on calcium lactate and produce limestone, which closes up the cracks, repairing the material.
“It is combining nature with construction materials,” Jonkers explains. “Nature is supplying us a lot of functionality for free — in this case, limestone-producing bacteria. If we can implement it in materials, we can really benefit from it, so I think it’s a really nice example of tying nature and the built environments together in one new concept.”
The team is currently testing the ability of the bacteria to resist sulfate attacks or extreme temperature variations. In addition, scientists seek to reduce the production cost of the material so that it becomes an affordable alternative in the market, since their commercial potential is very large.
The Conversation Prism by Brian Solis and JESS3 https://conversationprism.com/
Social Media not only keeps on growing but also changing. New vocabulary and new sites emerge and as sites lose popularity they disappear are quietly forgotten. The Conversation Prism above created by Brian Solis and JESS3 has gone through a number of iterations since its conception in 2008. This latest version is a visual map of the social media landscape. It’s an ongoing study in digital ethnography that tracks dominant and promising social networks and organizes them by how they’re used in everyday life. (The full size version can be found here.)
Below is a collection of social media terms and a short explanation for each.
