Scientists identify gene variations that determine lifespan

DNA sequence on computer screen
A new study has identified gene variations that determine life expectancy.
Sixteen gene variations linked to life expectancy, of which 14 are newly discovered, have been recently identified by specialists. They also revealed three genes whose low expression in the brain is linked with longevity.

In the United States, life expectancy is currently averaged at 78.8 years, according to data from the Centers for Disease Control and Prevention (CDC). They also identify the leading causes of death, naming heart disease, cancer, and chronic respiratory diseases as some of the main culprits.

Scientists have previously looked at our genetic makeup for clues that indicate how long each person is likely to live. However, until now, only two genes had been identified as linked with longevity (defined as living beyond age 85) in humans.

Lower back pain may all be in the mind, study suggests

New research suggests that persistent feelings of stiffness in the lower back may be some kind of self-protective ‘trick’ that the mind plays on us in order to prevent further injuries. A new study into the neuroscience of clinical pain suggests that perceptions of stiffness may not reflect the actual …
