  • Ultrasound aligns living cells in bioprinted tissues

    North Carolina State University researchers have developed a technique to improve the characteristics of engineered tissues by using ultrasound to align living cells during the biofabrication process. "We've reached the point where we are able to create medical products, such as knee implants, by pr more

  • Focussed ultrasound used to improve effects of cancer drugs

    Researchers have made a breakthrough in more precisely targeting drugs to cancers. Using ultrasound and lipid drug carriers (liposomes), a multi-disciplinary team of biomedical engineers, oncologists, radiologists and anaesthetists at the University of Oxford have developed a new way to improve the more

  • Oxygen therapy could help combat dementia in individuals with lung disease

    Breathing in additional oxygen improves the function of blood vessels in the brain of people with breathing difficulties caused by lung conditions, according to new research. These findings could have implications for future research aiming to prevent the development of diseases affecting the brain, more
