Cocaine happens to be one of the most illicit drugs in Europe and US. Yet, estimations say there are around 17 million users worldwide. This together, makes important the detection of cocaine and having devices able to precisely measure a wide range of cocaine concentrations in street samples. At TU Delft, together with the Netherlands Forensic Institute Lukasz Poltorak et al. have proposed a successful method which allows not only the detection of very different concentrations of cocaine but also the analysis and detection of cutting agents.
It is hard to imaging the making of the first transistor, now that we make them by the millions. How did we went from making a single, precious and delicate transistor to its mass production?
In a way we are living that very same moment with quantum entanglement (QE). Just months ago the QE of two particles meant a huge achievement. Today, ‘on demand’ entanglement links have been reported in Nature. Quantum entanglement is the pillar of a secure quantum internet. So a way to establish fast and stable links between particles is needed. Thanks to Prof. R. Hanson (QuTech and Kavli Institute of Nanoscience, TuDelft), we are at the verge of QE mass production.
As it is explained at TuDelft website “First of all, they demonstrated a new entanglement method. This allows for the generation of entanglement forty times a second between electrons at a distance of two metres. Peter Humphreys, an author of the paper, emphasises: ‘This is a thousand times faster than with the old method.’ In combination with a smart way of protecting the quantum link from external noise, the experiment has now surpassed a crucial threshold: for the first time, entanglement can be created faster than it is lost.”
Michel van Baal kindly asked for our help in the making of a picture of quantum network. We feel kind of proud been close witnesses of these important discoveries.
FRET is a mechanism describing energy transfer between two light-sensitive molecules. Dr. Juan Cabanillas (IMDEA Nanociencia) et al. have studied different fluorene-based polymer blends to produce low threshold lasers operating between 540 and 590 nm (green/yellow). They’ve established the optimal conjugation length of the polymers (number of units) which produces a 4 times increase in optical gain and a 34 reduction in amplified spontaneous emission threshold.
This research has appeared in the cover of Advanced Functional Materials.
A few months ago we made a press release on the recent work of Prof. Pere Cusachs: a beautiful research where they study how the cell interacts with its environment.
We help them made a beautiful image for them, picturing a cell exploring its surroundings. That image got particularly popular, making it to PhD manuscript covers and even t-shirts.
Finally, a different version of the picture made it to the cover of a biology journal: Trends in Cell Biology
About 4 years ago Prof. Jose Ángel Martín Gago approached me to talk me about the NANOCOSMOS project. As they explain in their website, “NANOCOSMOS will take advantage of the new observational capabilities (increased angular resolution) of the Atacama Large Millimeter/submillimeter Array (ALMA) to unveil the physical and chemical conditions in the dust formation zone of evolved stars”. Simply put, they are studying the debris stars create and the role this dust plays in the life/death recycling story of the universe.
This is a huge ERC funded project directed by Prof. José Cernicharo which has put together research groups from Spain and France.
And this is where Natalia Ruiz Zelmanovitch (Public Information Officer of the project) appears. She happens to be the most-committed-with-outreach-and-dissemination-of-science I’ve ever met. And she wants to tell the story of the NANOCOSMOS project. And she wants to tell it right.
She is behind the production of “NANOCOSMOS: un viaje a lo pequeño.” Here you can watch the trailer:
Scixel has been in charge of the 3D visualizations of the space: stars, nebulae, galaxies and planetary systems. We have been working with the Nanocosmos people for a few years now and I can tell you, if I know Natalia enough, this is just the beginning. So, stay tunned!
We participate in outreach projects every time we can. And this is one of those. Nanokomik is a comic contest organized by the research centers CIC nanoGUNE and the Donostia International Phyisics Center (DIPC). Last year’s challenge was to create a graphic story about a female or male comic superhero with “nanopowers”, that is, sophisticated skills or powers acquired through nanoscience and nanotechnology.
We created Miss Young, a superhero with the ability of been everywhere at the same time when nobody is observing her.
We didn’t win the contest but it certainly was a great experience to make our first comic in a traditional way.
Eukariotic cells face a hard to picture space problem: to pack a 2 meter long molecule into a 6 microns in diameter sphere. Not only that, the cell must be able to pack and unpack this DNA locally in order to perform its functions.
A protein called Condensin has been long known to be related to the DNA packing process, but until last year, the way this protein worked was still a mystery. Prof. Cees Dekker has directed the research that has unveiled this secret. For us, non biologist it is hard to understand how important this is and its repercussion, but the fact that it has been published in Science gives us a hint. This work is a collaboration between TuDelft (Netherlands) and EMBL (Germany).
Thanks to this research we know now how Condensin traps the DNA and uses its ring to drag the DNA forming a loop. Together with the people of TuDeflt we made this video explaining the motor function of this protein.
We are particularly proud of the music piece… hope its epicity expresses both the importance of the finding and the pride we’ve felt when they let us participate in the project.
Cells are able to perceive their surroundings by detecting forces. Interactions between cells and their ligands is essential to sustain the tissues functionalities, and detection of changes in the cell environment is of key importance to tissue growth, which includes embryogenesis or tumor proliferation. Cells are able to detect the position of molecules in their environment with nanometric precision and through forces, they are able to perceive their surroundings.
To illustrate their research, we designed this picture with the help of Roger Oria.
