Modifying mice memories
Scientists have been able to alter the emotional associations of memories mice by using a technique called optogenetics, which involves shining lights inside the brain. Roger Redondo explained to Georgia Mills how they reversed emotions at the brain cell level, and what this could mean for treating emotional trauma in…
Sex and back pain
The karma-sutra for back pain may soon be arriving. Within the UK and abroad, there are striking percentages of men and women that report experiencing back pain, especially in later life, and this may be causing the bedroom to take a backseat for these couples. Now, recent research carried out…

Bereavement suppresses the Immune System
Have you ever heard of someone dying of a broken heart? In fact, it is remarkably common for elderly people who were previously healthy to die soon after their spouse. But why? New research from the University of Birmingham has discovered that it is down to reduced functioning of the…

How to make energy from oil-eating microbes
One of the remarkable things about the Deepwater Horizon oil spill in the Gulf of Mexico four years ago was the fact that a lot of the contamination was cleaned up by bacteria which simply ate the oil.Now there's more understanding of how microbes exist in oil which could lead…
Remembering to live to a ripe old age
