Antimicrobial resistance: a small signal triggers bacterial conjugation via a hitchhiking mechanism
In several plasmids of pathogenic bacteria, scientists have identified a sequence that enables bacterial conjugation to take place via a hitchhiking mechanism. This discovery is important as it sheds light on the process and its role in antimicrobial resistance.

A bicentenary tribute to Louis Pasteur, Foreign Member of the Royal Society
To celebrate the bicentenary of Louis Pasteur's birth and pay tribute to this scientist who was a Foreign Member of the Royal Society, the Institut Pasteur and the Académie des sciences are organizing a symposium with support from the Royal Society. This symposium will present cutting-edge research in Louis Pasteur’s own research areas and promote international cooperation in science and...

Artificial intelligence: an online platform to improve molecular-level analysis of living systems
State-of-the-art super-resolution microscopes enable us to observe biological structures at resolutions approaching molecular scale. A good example is single-molecule localization microscopy (SMLM). Although this microscopy technique is widely used in life sciences, the vast majority of SMLM images produced are not shared with the scientific community. But these data have real value, not...

What is long COVID ?
In May 2020, while the first wave of the COVID-19 outbreak was coming to an end in France, initial reports emerged of patients with some persistent symptoms several weeks or months post-infection. This phenomenon, now referred to as "long COVID" (or post-COVID-19 syndrome) affects over 20% of patients after 5 weeks and over 10% of patients after 3 months. Serious or severe forms of initial SARS-...

Conserving microbiota to tackle antibiotic resistance
Our microbiota provide an additional means of fighting off infections but can be adversely affected by antibiotic therapy. A study modeling microbial populations and their response to drugs offers potential for improving our understanding of antibiotic resistance and tackling it more effectively.

Virtual reality effective in preoperative planning for breast cancer surgery
A recent study evaluates the benefits of 3D visualization for surgeons analyzing MRI breast images. Based on the innovative DIVA technology, developed jointly by the Institut Pasteur and the Institut Curie, a new software application gives surgeons immersive 3D visualizations of MRI images, enabling them to analyze situations more quickly and determine the best approach to take.

Cancer: the role of substrate rigidity in tumor migration
Among the characteristics defining our constituent organs are their different rigidities. Changes in these physical properties occur during tumor development. Tumors use the rigidity of their surrounding environment to facilitate their migration to neighboring tissue, which in turn facilitates tumor invasion and metastasis. Scientists at the Institut Pasteur have identified a new element enabling...

How does the Kaposi’s sarcoma herpesvirus enter the cell? A new understanding
The Kaposi's sarcoma herpesvirus causes skin cancers, especially in immunocompromised people. A recent study offers new modellings of one of the virus’ a surface proteins, and its receptor, on human cells.

Virtual reality helps explore how the brain initiates movements
To escape predators or to acquire rewards, animals need to anticipate movements. How does the brain accomplish this task? Scientists at the Institut Pasteur have recorded the activity of neurons in the frontal cortex of mice that were trained to run towards rewards. They find that seconds before the mice start running, neurons show increasing “ramps” of activity.

A better picture of Listeria reservoirs and global spread
Two recently published studies by Institut Pasteur researchers and collaborators shed light onto the ecology and evolution of the bacterial pathogen Listeria monocytogenes. These publications highlight the high prevalence of faecal carriage of the pathogen in asymptomatic hosts, its dependence on the microbiota, and the global spread of its main clinical clone.
