Doctors may soon have a better understanding as to why people gamble.

This could lead to better treatments for addicts.

Researchers at the California Institute of Technology said they have pinpointed the part of the brain that controls gambling behavior.

Scientists used MRI scans and found pathways in the brain that weigh risk and reward.

They said understanding these pathways could be the key to helping those with impaired decision-making skills.

A new study claimed ugly people are more likely to commit crimes.

Professors from Colorado and Georgia analyzed a survey of 15,000 high school students in 1994.

The survey was cross-matched with criminal records 10 years down the line.

Researchers found those who considered themselves ugly were convicted of crimes.

Researchers said the connection goes back to how unattractive people are treated differently as a child because negative interactions have lasting impacts.
