‘Human On A Chip’ Is The Latest Technology That Can Replace Animal Testing

Scientists at Lawrence Livermore National Laboratory are working on a technology that can replicate vital human tissues on microchips.


Motorized molecules drill through cells

Φωτοκατευθυνόμενες «μοριακές μηχανές» χρησιμοποιήθηκαν για την διάτρηση της εξωτερικής μεμβράνης σε μεμονωμένα κύτταρα, υποσχόμενες είτε την μεταφορά θεραπευτικών ουσιών μέσα σε πάσχοντα κύτταρα, είτε την άμεση καταστροφή των νεκρωμένων._Πυθεύς

New weapon against Diabetes

Researchers have used the simplest approach yet to produce artificial beta cells from human kidney cells. Like their natural model, the artificial cells act as both sugar sensors and insulin producers._ ETH Zurich

Scientists develop very early stage human stem cell lines for first time

Scientists at the University of Cambridge have for the first time shown that it is possible to derive from a human embryo so-called ‘naïve’ pluripotent stem cells – one of the most flexible types of stem cell, which can develop into all human tissue other than the placenta.__The University of Cambridge

3D-mapping a new drug-delivery tool

Scientists from EPFL and Nestlé have developed a new method that can “see” inside dispersed cubosomes (dispersed cubic liquid crystalline phases) with unprecedented detail. The breakthrough can help to improve their design significantly for better drug or nutrient delivery._EPFL

New life for pig – to – human transplants

Pale on its bed of crushed ice, the lung looks like offal from a butcher’s counter. Just six hours ago, surgeons at the University of Maryland’s medical school in Baltimore removed it from a hefty adult pig and, with any luck, it will soon be coaxed back to life, turning a rich red and resuming its work in the chest of a six-year-old baboon._nature journal

Blue Light Sets the Beat in Biological Pacemaker

Technion researchers have successfully established a new approach for pacing the heart and synchronizing its mechanical activity without the use of a conventional electrical pacemaker. This novel biologic strategy employs light-sensitive genes that can be injected into the heart and then activated by flashes of blue light.
