Scientists have shown, using imaging tests, that fructose can trigger brain changes that lead to overeating. They found that after drinking a fructose beverage, the brain doesn’t register the fullness feeling as it does when simple glucose is consumed.
The enzyme protein kinase M-ζ (PKM-ζ) was thought to be a fixture of long-term memory, as its inhibition could erase old memories, whilst adding it could strengthen faded ones. Two independent groups have challenged the role of this memory molecule by developing mice that completely lack it and show no detectable memory problems.
A brainwave-controlled helicopter project was fully funded by Kickstarter, and is hoping to come into homes very soon. The project was initially posted as a DIY hack on Instructables two years ago, and it’s supposed to be an educational toy.
By investing $11.4 million to change out aging fluorescent lights in the ISS’s U.S. Orbital Segment, NASA hopes to prevent astronaut insomnia and to help space station crews sleep better aboard the International Space Station.

Dystextia is when a person sends garbled messages, it could simply be that the auto-correct is turned off or that there is something else is going on. Scientists have discovered that dystextia could indicate some kind of a stroke, if taken in context with other symptoms.
