Currently patients and oncologists use detailed pathology reports, genomic tests, and imaging to make decisions aboutbreast cancer prognosisand therapy. However, these tools have varying degrees of accuracy, particularly for predicting the course of early-stage disease. In those cases the tumor is sma...
Science Minister Cristina Garmendia said the hospital "has the first lab in the world dedicated to producing bioartifical organs for transplant usingadult stem cells." Three years ago the hospital became the first in the world to usestem cellsfrom a patient's fat tissue, extracted through liposuc...
Like all cells in our bodies, nerve cells are encased in a membrane, a thin layer of fatty tissue that walls off the outside world from the cell's interior. And like other cells, nerve cells use a complex system of proteins as sensors, switches and activators to scan the outside world...
Until now, scientists performed pulsed EPR spectroscopy with a few tens of GHz of electromagnetic radiation. Using the UC Santa BarbaraFree Electron Laser, which emits a pulsed beam of electromagnetic radiation, the multi-university team was able to use 240 GHz ofelectromagnetic radiationto power an...
Sir Charles Kuen Kao (4 November 1933 – 23 September 2018) was a physicist and electrical engineer who pioneered the development and use of fibre optics in telecommunications. In the 1960s, Kao created various methods to combine glass fibres with lasers in order to transmit digital data, which...
“Our Monte Carlo simulations make predictions, and we compare those to our experimental data. That allows us to validate and improve the Monte Carlo simulations,” say Orebi Gann. “We can use that improved Monte Carlo to predict performance in other scenarios. It’s the step that allows us...
The interest in the use of a pH-responsive drug vehicle is due to the fact that they can reduce undesired drug release during transportation in blood circulation and improve the effective release of the drug in the tumour tissue or within tumour cells [105, 106]. 14184 Metal-Organic ...
Cell counting underpins numerous applications, spanning basic research through to the development and production of cell therapies. In recent years, manual cell counting methods have largely been replaced by the use of automated cell counters, which are both faster and more accurate, especially for co...
Named the “Method of the Year” byNature Methodsin 2010, optogenetics has been steaming forward steadily with new developments. Optogenetic tools use a combination of light and genetic engineering to control the electrical activity of a neuron with nary a patch pipette. The field...
rather than continuous random trial-and-error. For example, to reach fruit hanging out of reach in its pen, a chimpanzee learned to use sticks to get the food, or stacked boxes to get it. Then, if tables were substituted for the boxes, the chimp would immediately use them instead.« ...
