*With a budget/without a budget*
Yesterday was an awesome day (10.10.2018). Students from public and private Universities in Colombia (my native country) marched for a better financing to public universities. In short words, there is a problem with the money that is earmarked for these sectors which is not enough to cover the actual requirements to the normal operation of the universities. A banner from today ☺

Pure nitric acid barely reacts with copper metal, due to an effect called passivation. However, when water is added, the acid is diluted and passivation no longer occurs.
The nitric acid can then freely attack the metal, forming blue copper nitrate and a lot of nitrogen dioxide gas.
A full explanation of this is given in my video on nitric acid on YouTube.

A physics lecture 90 years ago: The lecturer, Paul Scherrer, was appointed Professor of Experimental Physics at ETH Zurich in 1920 at the age of only 30. As early as 1916, together with Peter Debye, temporarily Professor at ETH, he developed an experimental method for determining the structure of crystals using X-rays. In 1936, Debye was awarded the Nobel Prize in Chemistry for this method, which is still known today as the Debye-Scherrer method.

The Nobel Assembly at Karolinska Institutet has today decided to award the 2018 Nobel Prize in Physiology or Medicine jointly to James P. Allison and Tasuku Honjo “for their discovery of cancer therapy by inhibition of negative immune regulation.” Cancer kills millions of people every year and is one of humanity’s greatest health challenges. By stimulating the inherent ability of our immune system to attack tumour cells this year’s Nobel Laureates have established an entirely new principle for cancer therapy.
James P. Allison studied a known protein that functions as a brake on the immune system. He realised the potential of releasing the brake and thereby unleashing our immune cells to attack tumours. He then developed this concept into a brand new approach for treating patients.
In parallel, Tasuku Honjo discovered a protein on immune cells and, after careful exploration of its function, eventually revealed that it also operates as a brake, but with a different mechanism of action. Therapies based on his discovery proved to be strikingly effective in the fight against cancer.
Allison and Honjo showed how different strategies for inhibiting the brakes on the immune system can be used in the treatment of cancer. The seminal discoveries by the two laureates constitute a landmark in our fight against cancer. .

More #FluorescenceFriday rainbows! These are the luminescence of ligands (blue) and different iridium(III) anticancer complexes (green to red). Thanks to University of Murcia Ph.D. student Gloria Vigueras for sharing! Her research focuses on the design and synthesis of new luminescent iridium complexes for cancer treatment.⠀⠀⠀⠀⠀⠀⠀⠀⠀
