Thoth Technology, a Canadian tech company, has recently filed a patent for a 12.4 mile high (i.e. about 20 kilometer tall reaching the stratosphere, and about 20 times higher as compared to Dubai’s Burj Khalifa) “space elevator” that can become an alternative to rocket for astronauts, i.e. this invention will help to launch astronauts as well as tourists into orbit.

According to the patent of the company, it will be an inflatable, pneumatically pressured tower having a liftoff point (platform to launch) to space at the top. According to the company, this invention will help to save over 30% of the fuel of a conventional rocket.

“From the top of the tower, space planes will launch in a single stage to orbit, returning to the top of the tower for refueling and reflight,” stated Brendan Quine, who is the inventor of the ThothX Tower.

This invention will help to launch the rocket in a horizontal manner by removing the requirement for vertical launch, i.e. flight will be much like a passenger plane.

“In our concept, you ascend electrically and remove the whole vertical launch phase,” Quine stated. “Then you get into a space plane, which is like a passenger jet, and take off horizontally.”

This tower will serve not only for the launch of astronauts but it would also help in the generation of wind-energy, scientific research, communications, and tourism (as told earlier).

It is still on the paper but patent is showing that the company has moved a step to bring the physical product.

Detection of Alzheimer’s disease with a digital pen

Alzheimer’s disease is a degenerative brain disorder that is similar to senile dementia except that it begins in the later stages of life, usually after 40 years. Among the first signs and symptoms of the disease are impaired memory along with impaired thought and speech. However, these signs and symptoms appear after a significant damage to the brain.

This disease (along with many other psychiatric problems such as Parkinson’s) can be detected by doctors and experts with the help of drawing and/or writing. However, doctor’s or expert’s opinion matter a lot in detection of such problems, and these problems become apparent only when the patient has already advanced to serious conditions. Without an expert’s opinion, it is difficult to confirm the problem.

Recently, MIT researchers have developed a digital pen that is attached to a custom tracking software. This digital pen can help in finding the condition in early stages by knowing not only what the person draws but also how he/she draws an image or diagram. A simple fact is that healthy people spend more time in thinking, whereas people with memory problems spend a lot more time in thinking and patients of Parkinson’s disease struggle with the process of drawing.
