The world’s most powerful acoustic tractor beam could pave the way for levitating humans

Acoustic tractor beams use the power of sound to hold particles in mid-air, and unlike magnetic levitation, they can grab most solids, liquids or even small insects and food. For the first time University of Bristol engineers have shown that it is possible to stably trap objects larger than the wavelength of sound in an acoustic tractor beam. This discovery opens the door to the manipulation of drug capsules or micro-surgical implements within the human body. Container-less transportation of delicate larger samples is now also a possibility and who knows, this could be a step towards levitating humans.

Immediate breast reconstruction after mastectomy does not delay start of chemotherapy or radiotherapy – but may increase risk of complications and readmission

Having immediate reconstruction following a mastectomy does not delay the start of a patient’s adjuvant breast cancer therapy but may increase the likelihood of complications requiring hospital readmission in the first six weeks after surgery, according to new research led by researchers at the University of Bristol and the Royal Liverpool University Hospital presented at the UK Interdisciplinary Breast Cancer Symposium (UKIBCS) in Manchester – hosted by leading charity Breast Cancer Now.
