Vaccine made from stem cells blocks cancer in mice
A vaccine made from induced pluripotent stem cells, or iPSCs, has been effective in preventing cancer in mice. The irradiated iPSCs blocked breast, lung and skin cancers in the mice and kept tumors removed by surgery from coming back.
Probe developed to look inside lungs for bacterial infections
Scientists have developed a probe that can go inside the lung and quickly detect dangerous bacterial infections. The imaging technology, called Proteus after the microscopic vessel in the film “Fantastic Voyage,” could help identify the specific bacteria and order the appropriate antibiotic without having to wait days for lab results.
