Hafnium nanoparticles that home onto microfractures in bone make the tiny cracks visible in spectral or color computed tomography (CT) imaging. Researchers at the University of Illinois at Urbana-Champaign and the University of Maryland created the nanotechnology to work in conjunction with spectral molecular imaging developed by New Zealand-based MARS Bioimaging Ltd. (MBI). The research appeared in Advanced Functional Materials.
One necessary step to fend off a dystopian future of medical care without antibiotics is the development of new antibiotics. Another is improved deployment of existing ones, a feat which will take, among other things, better antibiotic susceptibility testing (AST).
Researchers at the RIKEN Center for Integrative Medical Science (IMS) and Keio University School of Medicine (KUSM) in Japan have discovered that people ages 110 or longer, the so-called supercentenarians, have elevated blood levels of CD4+ cytotoxic T lymphocytes (CTLs).
