The most groundbreaking science of 2019: five milestones that have made history

The Science Week, held from November 4 to 17, makes us reflect on the most important scientific milestones of what we have in 2019. We dive into cells capable of fighting cancer and farewell to great scientists, such as Margarita Salas.

We take advantage of Science Week to discover the five most relevant findings of 2019. Science advances rapidly – perhaps not as much as we would like – and brings with it such innovative projects as exoskeletons or work with stem cells to fight cancer.

A brain-controlled exoskeleton

At the beginning of October, news came to light that fueled hopes in the field of mobility. A quadriplegic man was able to move his arms and legs thanks to an exoskeleton that controlled with the brain.

After 10 years of research, they have finally been able to carry out this kind of “motorized armor” that works with electrodes implanted in the skull. These “capture the signals sent by the brain and translate them into motor signals,” explained Alim-Louis Benabid, a neurosurgeon who works in the development of deep brain stimulation for movement disorders.

The Nobel Prize for Medicine is committed to the fight against cancer

Last October Scientists William G. Kaelin Jr, Gregg L. Semenza, and Sir Peter J. Ratcliffe received the Nobel Prize for Medicine for their discoveries on how cells perceive and adapt to oxygen availability.

With this work they demonstrated that our immune system is able to recognize tumor cells as strange. Thus, they worked on systems that neutralized this threat, including the so-called bullets pages. These are drugs that enhance the immune system’s response to these types of cells guilty of diseases such as cancer.

Music modifies the taste of cheese

How nice to discover that science can also improve gastronomy. Yes, it sounds strange, but as long as it tastes delicious … A group of researchers said that cheese acquires a different flavor when it “listens” to music.

Several types of this dairy product were exposed to different musical genres: “Cheeses exposed to hip-hop in particular had a clearly stronger smell and a stronger and spicier flavor than other cheeses,” concluded Michael Harenberg, director of the study .

The solar system poses in the foreground

NASA orbits Jupiter thanks to the Juno probe. From this action, some scientists have launched JunoCam, which allows taking pictures of the planet.

In the most visual era that the human being has lived so far, these types of milestones do not go unnoticed. The photographs taken are amazing and the most revolutionary thing is that all those interested can participate through the JunoCam website.

Margarita Salas dies, scientific reference of the twentieth century

At the age of 80 and with a great legacy marked by findings such as DNA polymerase, Margarita Salas has died. Currently, she was still working as an honorary researcher and professor at the Severo Ochoa Molecular Biology Center of the Autonomous University of Madrid and the CSIC The scientist has been awarded multiple times and has obtained great recognition for her work and research.
