Researchers engineer human bone marrow tissue
Every day in the bone marrow several billion blood cells are formed. This constant supply is ensured by blood stem cells located in special niches within the marrow. These stem cells can multiply and mature into red and white blood cells, which then leave the bone marrow and enter the blood ... more
Designer cells: artificial enzyme can activate a gene switch
Complex reaction cascades can be triggered in artificial molecular systems: Swiss scientists have constructed an enzyme than can penetrate a mammalian cell and accelerate the release of a hormone. This then activates a gene switch that triggers the creation of a fluorescent protein. The fin ... more
Malaria detectable in olfactory cocktail
ETH researchers have discovered odour profiles typical of people infected with acute or asymptomatic malaria. This is a first promising step towards a low-cost diagnostic test that can be used in the field in developing countries.
Malaria is still a deadly disease in tropical and subtropica ... more
