How cells know which way to go

( Source: MEDICA.de )

Graphic: cells moving through the body [28/10/2014] Amoebas aren't the only cells that crawl: Movement is crucial to development, wound healing and immune response in animals, not to mention cancer metastasis. In two new studies from Johns Hopkins, researchers answer long-standing questions about how complex cells sense the chemical trails that show them where to go – and the role of cells' internal "skeleton" in responding to those cues.How cells know which way to go - Read more

( Source: MEDICA.de )

[22/10/2014] Patients in intensive care units do not just have to struggle with the consequences of a severe injury or disease – they are also subject to acute glucose fluctuations that compromise the healing success. These sometimes happen so quickly that they cannot be caught in time with existing discrete measurement methods.Continuous glucose monitoring: “Our method is based on the principles of infrared photometry“ - Read more

Photo: Two-color STED image of a glioblastoma [10/10/2014] For a long time optical microscopy was held back by a presumed limitation: that it would never obtain a better resolution than half the wavelength of light. Helped by fluorescent molecules the Nobel Laureates in Chemistry 2014 ingeniously circumvented this limitation. Their ground-breaking work has brought optical microscopy into the nanodimension.Surpassing the limitations of the light microscope - Read more
