Bone stimulation for fracture healing: What''s all the fuss?

Lowintensity pulsed ultrasound. In vitro studies suggest that ultrasonic stimulation enhances bone healing by increasing the incorporation of calcium ions in cultures of cartilage and bone cells and stimulate the expression of numerous genes (including genes for Aggrecan, IGF, and TGFβ) involved in the healing process. 4 The most important effect that ultrasound has on bone healing may be

New research unlocks clues about Earth''s magnetic field

Jan 22, 2020 · Earth''s magnetic field 4 billion years ago. Previous research by Tarduno found that Earth''s magnetic field is at least 4.2 billion years old and has existed for nearly as long as the planet. Earth''s inner core, on the other hand, is a relatively recent addition: it formed only about 565 million years ago, according to research published by Tarduno and his colleagues earlier this year.
