The connection between food and memory is one of those fundamentally human experiences we can all relate to. A compelling new study from the University of Southern California has revealed an intriguing explanation behind this phenomenon, and it illustrates how strongly the “second brain” in our gut communicates with our brain.
Inside our gastrointestinal tract lies a massive mesh of neurons often referred to as our “second brain.” While this neuronal control system primarily works to independently manage our digestive system, it also has been found to directly communicate with the brain via a long nerve, called the vagus nerve.
The vagus nerve has been found to mediate a great deal of metabolic communication between the gut and the brain. For example, one recent study revealed how feeding behavior, modulated by activity in the hippocampus, is directly activated by vagal nerve stimulation, mediated by signals from the gastrointestinal tract.

Speaking of Pangaea, this video shows how the present-day continents came to be formed from the Pangaea supercontinent about 240 million years ago, then shows what the Earth’s surface might look like 250 million years in the future, if the tectonic plates continue to move in predictable ways.
I hope this explanation is helpful. Of course all of this is scientific speculation, we will have to wait and see what happens, but this is my projection based on my understanding of the forces that drive plate motions and the history of past plate motions. Remember: “The past reveals patterns; Patterns inform process; Process permits prediction.”
Look at how quickly India slams into the Asian continent…no wonder the Himalayas are so high.

Replacing potatoes or rice with pulses can lower your blood glucose levels by more than 20 per cent, according to a first-ever University of Guelph study.
Prof. Alison Duncan, Department of Human Health and Nutritional Sciences, and Dan Ramdath of Agriculture and Agri-Food Canada, found that swapping out half of a portion of these starchy side dishes for lentils can significantly improve your body’s response to the carbohydrates.
Replacing half a serving of rice with lentils caused blood glucose to drop by up to 20 per cent. Replacing potatoes with lentils led to a 35-per-cent drop.

DigiLens, a developer of transparent waveguide display technology, says it’s working toward a waveguide display which could bring a 150 degree field of view to AR and VR (or XR) headsets. The company expects the display will be available in 2019.
Founded in 2005, DigiLens has developed a proprietary waveguide manufacturing process which allows the company to “print” light manipulating structures (Bragg gratings) into a thin and transparent material wherein light can be guided along the optic and be made to project perpendicularly, forming an image in the user’s eye. While DigiLens isn’t the only company which makes waveguide displays, they claim that their process offers a steep cost advantage compared to competitors. The company says they’ve raised $35 million between its Series A and B investment rounds.
While DigiLens’ displays have primarily been used in HUD-like applications, the company is increasingly positioning its wares toward the growing wearable, AR, and VR industries. At AWE 2018 last week, DigiLens Founder & CTO Jonathan Waldern told me that the company expects to offer a waveguide display suitable for AR and VR headsets which could offer a 150 degree field of view between both eyes. He said that a single display could be suitable for AR and VR modes in the same headset by utilizing a liquid crystal blackout layer which can switch between transparent and opaque, something which DigiLens partner Panasonic has developed. A clip-on light blocker or other type of tinting film ought to be suitable as well.

Too bad the middle class is shrinking!
The rate of growth in residential rooftop solar photovoltaics (PV) in Australia since 2008 has been nothing short of breathtaking.
Our new research suggests that the households most likely to join in the solar spree are those that are affluent enough to afford the upfront investment, but not so wealthy that they don’t worry about their future power bills.
Australia now has the highest penetration of residential rooftop PV of any country in the world, with the technology having been installed on one in five freestanding or semi-detached homes. In the market-leading states of Queensland and South Australia this ratio is about one in three, and Western Australia is not far behind, with one in four having PV.
