Artificial Brain

The human brain is the center of the human nervous system and is a highly complex organ. According to BBC, A detailed, functional artificial human brain can be built within the next 10 years, a leading scientist has claimed. The team are trying to reverse engineer the brain.

Hundreds of undiscovered worlds in outer parts of our Solar System

This is really a good news. A galaxy is a massive, gravitationally bound system consisting of stars, an interstellar medium of gas and dust, and dark matter. Our Sun and Earth are part of the Milky Way galaxy. Basically the Sun is one of the stars in the Milky Way galaxy; the Solar System includes the Earth. Now scientist suggests more than half the Sun-like stars in the Milky Way could have similar planetary systems just like our solar system. In other words there may be many more worlds in our galaxy. From BBC news site:

Rocky planets, possibly with conditions suitable for life, may be more common than previously thought in our galaxy, a study has found.

New evidence suggests more than half the Sun-like stars in the Milky Way could have similar planetary systems.

There may also be hundreds of undiscovered worlds in outer parts of our Solar System, astronomers believe.

Future studies of such worlds will radically alter our understanding of how planets are formed, they say.

It is genetic – people keep repeating mistakes

Most people tend to learn from their mistakes and avoid making the same blunder twice. But we find lots of people making same mistakes again and again. Now scientist found a new relationship between a specific gene and those of us prone to repeatedly making the same mistakes. From the nature article:

A genetic mutation that helps to determine the extent to which certain people are doomed to repeat history.

Drug addicts, alcoholics and compulsive gamblers are known to be more likely than other people to have this genetic mutation, which leaves them with fewer receptors of a certain type in the brain. These receptors — called D2 receptors – are activated when levels of the neurotransmitter dopamine drop.
