Immune Cell Macrophage Responsible For Tissue Regeneration

Australian Regenerative Medicine Institute (ARMI) researchers have discovered that white blood cells called macrophages may hold the key to tissue regeneration. This discovery may help in new therapies involving repairing and regenerating tissues in the heart, spinal cord and lungs.

Researchers studying salamanders have noted that the reptile's ability to regenerate its tail without any sign of scars may be due to this immune cell. The researchers found that without the presence of macrophages, the salamanders do not regenerate a lost limb.

By studying this ability, the discovery can help in research towards therapies involving organs where damaged tissues can regenerate without scarring. Sensitive organs such as the heart and the spinal cord can benefit with this discovery. Researchers at ARMI are now looking to replicate this process with human tissues.

Transcranial Random Noise Stimulation (TRNS) Enhances Math Skills and Ability in Brain

Researchers have found that a non-invasive and harmless process known as Transcranial Random Noise Stimulation (TRNS) enhances the brain's ability in math skills and ability for as long as six months.

Transcranial Random Noise Stimulation is a form of brain stimulation where brain functions are modified by using weak electrical current over the scalp using contact electrodes. TRNS is one type of transcranial current stimulation where the stimulation current is varied randomly.

The principle behind this type of brain stimulation is that the electrical fields generated by the electrical currents modulate the activity of brain neurons and can enhance certain brain functions.

TRNS is a relatively new process but recent studies have already shown enhanced brain performance using this technique.
