A look back on this week in science:

• A study demonstrates that you can’t think with empathy and analysis at exactly the same time, and that these behaviors are controlled by two different parts of the brain, more commonly called the task-positive network (analytical) and default mode network (empathetic).
• A mathematical models demonstrates that it should be possible to test faster than light communication via quantum entanglement within the next few years. We will most likely discover it is impossible, but this is a falsification we previously thought was impossible.
• Canadian scientists have discovered that high cholesterol might be caused by a protein that blocks the liver’s ability to remove it from the body. In other words, high cholesterol isn’t necessarily the result of bad diet or lack of exercise.
• A step towards a male contraceptive pill works by removing sperm tails.
• Princeton research suggests that at least certain aspects of evolution are far from random, and highly predictable.
• Thousands of carbon nanotubes were successfully fitted onto a computer chip.
• Honey bees can tell the difference between the paintings of Picasso and Monet.
