CAN gentle doses of laser light help cells to heal? The technique is sometimes used to treat problems such as tinnitus and joint pain, but with no explanation for how these therapies work, there is scepticism over whether the effect is real. Now a physicist has come up with evidence that the physical forces generated by low-energy laser beams may switch on cells’ repair mechanisms.
This will support the growing body of evidence that laser therapy is beneficial. At the Joint International Laser Conference in Edinburgh, UK, last month, researchers reported promising results for fields as diverse as IVF and…
