People might once have considered oxygen a human right. But the pandemic has revealed that access to oxygen – in a pure form, for medical use – is a luxury in most low and middle-income countries. Getting access to pure oxygen for medical treatments is a complicated, expensive and often very dangerous business. The current […]
“ There is something at work in my soul, which I do not understand.” ― Mary Wollstonecraft Shelley (1797-1851), Frankenstein or The Modern Prometheus, 1818 Increasing advances in material’s science have enabled the design and production of materials capable of inducing specific cell behaviors, such as proliferation, migration or differentiation. Consequently, we are now able […]
Even if we firmly go down the path of the low-carbon economy, the energy transition to renewables is only just beginning. We live now in a world that is still very much fossil fuel-based and the landscape of a fully renewable-powered future has not yet been shaped (and we might have to wait a few […]
Imagine running on a cement footpath, and then suddenly through dry sand. Just to keep upright, you would have to slow down and change the way you run. In the same way, a walking robot would have to change its gait to handle different surfaces. Generally, we humans and most robots can only change how […]

A number of technologies and tools got a chance to prove themselves for the first time in the context of COVID-19. Three researchers working in gene-based vaccines, wearable diagnostics and drug discovery explain how their work rose to the challenge of the pandemic, and their hopes that each technology is now poised to continue making […]
Inherited or somatic mutations targeting genes which encode essential cell growth regulatory proteins favor the emergence of cancer. Cells carrying these mutations acquire growing and survival advantages that trigger the emergence of the tumor. A large number of tumor-associated mutations, as well as many mutations found in the germline of hereditary cancer patients, are single-nucleotide […]
Gliomas are the most prevalent subtype of primary brain tumours originating from mutations of the glia cells in the central nervous system. Gliomas are characterized by fast cell growth, strong invasion capability, and well-developed tumour vasculature. Although research and clinical trials have allowed significant progress in the comprehension and treatment of gliomas, they still have […]
Wearable devices are attracting increasing attention. The most familiar today are smartwatches and smart bands. The sensors in these devices monitor vital signs such as our temperature, heart rate, and even blood oxygen, but are unable to address biochemical parameters. One of the main reasons is the relatively short life of chemical sensors and biosensors […]
If you are a fan of the MARVEL universe, you will have noticed that many of its characters, such as Spiderman, Black Panther, Ant-Man or Wolverine, have superpowers based on the abilities of certain animals. Using the animal kingdom as a reference, and using the abilities of certain animals, is not something exclusive to comics […]
In spintronics, new memory and logic devices are being developed based on the use of spins of nuclei, atoms, or molecules, instead of electronic charges. The main advantages are an improved energy efficiency and speed of operation to store and process information. The ability of organic molecules to maintain magnetic multistability in nanoscale junctions will […]
