The U.S. has created a concept of rocket fuel for the return of astronauts from Mars to Earth

To implement this project successfully, some kinds of microbes have to be delivered to Mars.

The first are algae capable of producing carbon dioxide on the Red Planet. They are also able to generate glucose with the help of the Sun's rays. The latter are E. coli, which convert sugar into rocket fuel.

Plans are for spacecraft launched to Mars to run on liquid oxygen and methane (oxygen can easily be obtained from carbon dioxide on Mars).

Spray-on touch screen

Researchers at the University of Bristol has challenged the idea that touch screens are limited to 2D and rectangular shapes by developing an interactive display that can be sprayed in any shape.

They have created ProtoSpray, which you just spray on the surface, and attach electrodes to it. As a result, any object made of any material will be able to light up and react to human actions.

Future applications, announced by the creators: doorbells, interactive tourist signs, etc.

The safest countries in the world.

All countries were evaluated according to three criteria:
- risk of natural disasters;
- personal safety of residents;
- whether the country is at war or has preconditions for war.
