Science Ethics at CIG, 6th Edition, May 28, 2026

Research integrity is not just about extreme misconduct — it is also about the human biases that insidiously push science from responsible practice toward questionable habits, undermining reproducibility and credibility.

This seminar offers concrete tools and strategies applicable at the bench and largely relevant to any researcher, whatever their field—including if you attended last year, as content has been updated.

In this year’s keynote lecture, Joe Garner (Stanford University) proposes a powerful mindset shift in experimental design illustrated by examples from animal research, but broadly applicable beyond the animal lab: moving from “what did we control?” to “what did we choose to ignore — and at what cost?”.

When, where

  • Date : Thursday May 28, 1:00–4 :45 PM

About the keynote speaker

Joe Garner is Professor of Comparative Biomedicine at Stanford University, where his work on animal models and experimental design has made him one of the leading voices on reproducibility in biomedical research. His keynote challenges researchers to move beyond “what did we control?” and ask instead: “what did we choose to ignore — and at what cost?”

Talk abstracts

  1. Keynote lecture: Changing the scientific mindset in biomedical studies (Joe Garner). This seminar explores a necessary shift in perspective in biomedical research: moving from the question “What have we controlled for?” to a more critical one: “What have we chosen to ignore, and at what cost?” Using examples from studies employing animal models, it highlights six common blind spots that can compromise scientific conclusions: ignored differences in the biology of the animal model, ignored characteristics of the modeled human disease, ignored limitations of the measurements used, ignored environmental factors, ignored impacts of animal welfare, and ignored principles of experimental design and statistics. The seminar demonstrates how recognizing these implicit assumptions can improve the validity, reproducibility, and ethical foundations of biomedical research.
  2. Ethics at the bench (1): Experimental design and data presentation (Frédéric Schutz). This seminar examines sources of bias in research, with examples from mouse studies. It shows how bias can arise even when researchers act in good faith, and why safeguards such as controls, randomization, and blinding are essential. It also emphasizes that the goal of science is not to prove hypotheses but to challenge them rigorously. The seminar further explores how uncontrolled environmental variability—such as cage effects, where animals sharing a cage are not statistically independent—can influence experimental outcomes. Finally, it addresses bias in data visualization and reporting, highlighting how misleading graphs or ambiguous error bars can distort interpretation and emphasizing the need for transparent presentation of data.
  3. Ethics at the bench (2): Beautification, manipulation, and AI: ethics of scientific images (Romain Gosselin). This seminar examines ethical issues related to the handling and manipulation of scientific images in biomedical research, mostly focusing on immunoblotting. It emphasizes that digital images are full-fledged data that must be handled with the same rigor as any other dataset. The presentation discusses how choices made during image acquisition, processing, analysis, and reporting can introduce bias. It also reviews common questionable practices, such as excessive contrast adjustment, saturation, cropping, or duplication of image elements. Finally, the seminar highlights the concerns raised by the abrupt rise of generative artificial intelligence, which now enable the generation of highly realistic synthetic images indiscernible from genuine images. Implications for research integrity and the need for awareness, good practices, and appropriate detection tools are discussed.
  4. Presentation of the FBM Ombudsman (Christian Kern). The Ombudsman of the Faculty of Biology and Medicine (FBM) at UNIL will introduce his role and mission. He will explain the mechanisms for reporting suspected scientific misconduct, which may arise in all types of research—clinical or basic—and may involve human subjects, animals, or biological material. In cases of suspected misconduct, the Ombudsman acts as an advisory and guidance authority. The Ombudsman will present several examples of situations that may constitute breaches of scientific integrity in clinical practice or laboratory research.

AI@UNIL Day, June 2, 2026

The AI@UNIL Day is a research‑focused scientific event that brings together UNIL’s AI research community and AI experts from neighboring academic institutions. The event aims to showcase the breadth of AI research conducted at UNIL as well as within regional academic institutions.

More than a scientific meeting, it provides a space for exchange and collaboration, highlighting how artificial intelligence serves as a shared language across disciplines and strengthens connections both within UNIL and with the broader regional research ecosystem.

Through interdisciplinary dialogue and shared expertise, the AI@UNIL Day supports the emergence of new collaborative projects and promotes a dynamic, responsible, and inclusive approach to AI research.

Genome-wide association studies identify new candidate genes and tissues underlying resistance to a natural toxin in drosophilids

Abstract

Many insects can rapidly evolve resistance to artificial insecticides through changes in toxin target proteins. Over longer timescales, insects also evolve resistance to naturally occurring toxins to exploit new ecological niches, but the underlying mechanisms often remain poorly understood. A classic example is Drosophila sechellia, an extreme specialist for the ripe noni fruit of Morinda citrifolia. Noni is toxic for other insects-including D. sechellia’s close relatives Drosophila simulans and Drosophila melanogaster-due to this fruit’s high content of octanoic acid (OA). However, the mechanistic bases of OA susceptibility and resistance across species remain unclear. Here, we first show that the species-specific tolerance of OA is independent of these drosophilids’ distinct microbiomes. Screening large, genetically diverse panels of D. melanogaster and D. simulans strains revealed broad variation in OA resistance, with some lines surviving as well as D. sechellia. Resistance to OA does not correlate with resistance of these lines to other insecticides, implying a distinct toxicity mode of action. Genome-wide association and transcriptome-to-phenotype analyses identified multiple genes linked to OA resistance, with diverse expression patterns and functions, including those involved in epithelial septate junction formation and lipid transport. Loss-of-function analysis in D. melanogaster confirmed that at least 2 of these-Bez, a CD36-family fatty acid transporter, and CG13003, a putative extracellular matrix component-positively contribute to OA resistance. Integration of our findings with those from previous complementary genetic approaches supports a model in which OA has no singular target, and that resistance is defined by multigenic and multitissue defense mechanisms.

Palmitic and oleic acids in type 2 diabetes mellitus

Abstract

The most common dietary and plasma fatty acids (FAs), palmitic and oleic acids, have opposing effects on the risk of developing insulin resistance and type 2 diabetes mellitus (T2DM). Palmitic acid has been strongly associated with the presence of T2DM, while oleic acid has not and may even counteract the detrimental effects of palmitic acid. Despite this, recent cohort studies have shown no association or even conflicting results, questioning these roles. This review summarizes the recently discovered molecular mechanisms by which palmitic acid inhibits insulin sensitivity and influences the development and progression of T2DM and how oleic acid can attenuate these effects. It also addresses future challenges in the growing field of dietary FA metabolism in T2DM research, which may help assess their actual impact on this condition.
