Louis Pasteur was born in Dole on December 27, 1822. The Pasteur family left the town of Dole in August 1825. After five years in Marnoz, Jean-Joseph Pasteur rented a tannery in Arbois in 1830.In the 1831 register of house visits, he is mentioned at 83 rue de Courcelles: "Pasteur Jean-Joseph, tanner, age 39, from Besançon. Jeanne Etiennette Roqui his wife, 37 years old, from Marnoz 4 children: Jeanne-Antoine 11 years old. Louis 9 years old. Joséphine 5 years old. Emilie 3 years old. A worker, Eloy Dole, 25 years old, from Poligny". At that time, Arbois and its suburbs had nearly 7000 inhabitants. The young Pasteur first attended the mutual education school and then the municipal college. After failing in Paris in 1838 to prepare for the baccalaureate, Pasteur studied rhetoric in Arbois and then, in 1839, at the royal college in Besançon. In 1842, Pasteur entered the École normale supérieure. In 1849 he became a professor at the faculty of Strasbourg, 1854 professor and dean of the new faculty of sciences of Lille, 1857 Pasteur was at the Ecole normale supérieure as administrator and director of scientific studies.In spite of his high functions, Pasteur and his family always came back to Arbois, it was a return to their roots."If there is no Arbois, there is no Pasteur," said the writer and academician Erik Orsenna.
路易·巴斯德于1822年12月27日出生在多尔。1825年8月,巴斯德一家离开了多尔镇。在马尔诺兹待了五年之后,让-约瑟夫·巴斯德于1830年在阿尔布瓦租了一家制革厂。在1831年的家访记录中,他在库尔塞勒街83号被提到:“巴斯德·让·约瑟夫,皮匠,39岁,贝桑帕尔松人。”妻子Jeanne Etiennette Roqui, 37岁,与Marnoz育有4个孩子:Jeanne- antoine 11岁。路易斯9岁。jossamphine 5岁。艾米丽,3岁。一个工人,埃洛伊·多尔,25岁,来自波利尼。当时,阿尔布瓦及其郊区有近7000名居民。年轻的巴斯德先是上了互助教育学校,然后上了市立学院。1838年,巴斯德未能在巴黎获得学士学位,于是他在阿尔布瓦学习修辞学,1839年又在贝桑皇家学院学习修辞学。1842年,巴斯德进入École normale supersamrieure。1849年他成为斯特拉斯堡学院的教授,1854年成为里尔新成立的科学学院的教授和院长,1857年巴斯德在高等师范学院担任行政人员和科学研究主任。尽管巴斯德身居高位,但他和他的家人总是回到阿尔布瓦,这是对他们根源的回归。“如果没有阿布瓦,就没有巴斯德,”作家兼院士埃里克·奥塞纳(Erik Orsenna)说。

Vaccination, the transmission of "vaccine", a benign disease of cows, to immunize human beings against smallpox, was invented by Jenner at the end of the eighteenth century. Pasteur, convinced that the vaccine microbe was an attenuated form of the smallpox microbe, showed that, similarly, attenuated forms of other microbes immunized against animal diseases. When applying this principle to rabies, he realized that, in this case, the vaccine was in fact composed of dead microbes. One of his students immediately exploited this result to devise a vaccine against typhoid. The vaccines against diphtheria and tetanus, in 1921, opened a new route, that of immunization with molecules from the pathogenic microbes. Molecular biology then allowed the production of the immunogenic molecules by microorganisms such as yeast, or immunization by genetically modified viruses or messenger RNA inducing our own cells to produce these molecules.

Over a century after the first description of a polymorphism controlled by a supergene, these genetic architectures still puzzle biologists. Supergenes are groups of tightly linked loci facilitating the co-segregation of combinations of alleles underlying alternative, complex adaptive strategies. The suppression of recombination at supergenes is generally caused by polymorphic chromosomal rearrangements, such as inversions. The existence of inversion polymorphisms and supergene raises theoretical and empirical questions. Why do these architectures evolve? How can alternative combinations of alleles be formed? How and why is polymorphism maintained? The purpose of this paper is to provide answers to these questions by reviewing recent advances in the study of Heliconius numata, an Amazonian butterfly displaying a striking diversity of wing color patterns. In a broad context, this review highlights mechanisms that play an important role in the evolution of new genomic architecture and in the adaptation of species.

In 2022, the burden of cholera-an acute watery diarrheal disease caused by Vibrio cholerae serogroup O1 (or more rarely O139) bacteria, which produce cholera toxin-remains high in many African and Asian countries. In the last few years, microbial genomics has made it possible to define the bacterial populations responsible for cholera more precisely. It has been shown that the current, seventh pandemic is due to a single lineage with a reservoir in the countries of the Bay of Bengal (India and Bangladesh). There have been several transmissions of the causal agent of cholera from this region to Africa, Asia and Latin America, suggesting a human-to-human transmission of the disease. Microbial genetics can help to fight this scourge by providing insight into cholera epidemiology and through its use in disease monitoring, thereby contributing to the achievement of the World Health Organization's goal of reducing cholera deaths by 90% by 2030.

Tick-borne infectious diseases are increasing, driven by geographic expansion of ticks. Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne virus of the family Nairoviridae that poses serious threat to public health. CCHFV can cause severe forms of hemorrhagic fever with high case fatality rates (CFR) (10-40%) and can be transmitted from human to human. Until a few years ago, no cases of CCHF had been reported in western Europe. However, high seropositivity rates in wildlife and detection of multiple strains of CCHFV in ticks in Spain suggest that CCHFV enzootic cycle has been established in some areas of southwestern Europe. As far as CCHFV-associated morbidity and mortality are concerned, there are no approved therapeutic options or US/EU licensed vaccines for treatment. Here we discuss some eco-epidemiological aspects as well as public health and socio-economic impacts associated with CCHFV circulation and outbreaks. We also emphasize that it has become essential to identify key inter-species transmission processes of this group of pathogens, to understand basic molecular mechanisms of their replication, and to define their pathogenic potentials.

Sensory cortex encompasses the regions of the cerebral cortex that receive primary sensory inputs and is crucial for conscious sensory perception in humans. Yet, some forms of perception are possible without sensory cortex. For example in animal models, the association of a sound detection to a simple behavior resists to the inactivation of auditory cortex. In contrast, post-training inactivation experiments conducted in visual or somatosensory cortex led to much stronger effects. Here we show that muscimol inactivation of visual or auditory cortex in the same detection protocol transiently abolishes visual but not auditory detection. We also observe that cortex-dependency correlates with longer reaction times. This suggests that auditory cortex is more easily bypassed by other circuits for stimulus detection than other primary sensory areas, which may be due to timing differences between auditory and visual associations.

Cancer evolution was long-reduced to a genetic equation. The latest technological and subsequent conceptual advances, catalyzed by single-cell approaches, now begin to reveal the long-suspected part played by epigenomic and transcriptomic mechanisms in cancer evolution. Lie ahead numerous challenges to integrate multi-modal measurements of individual cancer cells over time and space, while aiming for better disease management and the discovery of therapeutic targets and biomarkers.
