2025 was a breakthrough year for human-relevant science. 🧪

Behind the scenes, our SAO team spent thousands of hours moving this work forward.

We’re proud to share a few highlights from an impactful year ⬇️

Onward to an even more ambitious 2026! 🎉

Art as a tool for change 🎨🎭

In this paper, Victor J. Krawczyk of the University of South Australia examines how artworks depicting animal suffering in laboratory settings can evoke “moral shock,” a concept describing visceral emotional responses that challenge expectations.

#philsky #philsci
A quote from the linked paper: “In both works, the animals are imparted with a sense of being vulnerable, beautiful, and sacred, which takes them out of the mundane scientific–organizational space of animal research and testing facilities. ... They can shock people in a manner that swells with compassion for animals in these organizational spaces by showing its current limitations for animals to live well in research and testing facilities.” Attributed to author Victor J. Krawczyk, Journal of Aesthetics & Culture (2025) DOI: 10.1080/20004214.2025.2579371. Also pictured is the reproduced painting, “Baboon Heart Transplant” (1985) by Sue Coe and a photograph of the “Lush animal testing campaign” (2012) by Nicole Cataldo-Davies.

In this mini-review, @unisouthampton.bsky.social & @humaneworldorg.bsky.social scientists highlight recent advances in human-relevant, complex in vitro systems for studying #Alzheimers, exploring the effects of pathogens, environment, & gut-brain axis on neurodegeneration & AD risk.

#neuroskyence
Figure 1 from the Frontiers in Toxicology paper "Beyond the amyloid hypothesis: leveraging human-centered complex in vitro models to decode Alzheimer’s disease etiology" by Matthew Price and Francesca Pistollato (doi: 10.3389/ftox.2025.1753572). The figure caption reads, "Diagram illustrating how gut–brain axis disruption, environmental toxicants, and pathogen infections could contribute to the development of Alzheimer’s disease–related neuropathology, such as amyloid plaque formation, neurofibrillary tau tangles, blood–brain barrier leakage, neuroinflammation, synaptic dysfunction, and neuronal loss. Complex in vitro models, including brain organoids and organ-on-a-chip systems, enable these mechanisms to be replicated and studied under controlled and human-relevant conditions."

Isolation doubles death risk for female 🐭

New study shows cage mate number impacts survival: solo females were 2x likelier to die than group-housed.

Housing conditions often go unreported, ⬆️ bias & ⬇️ reproducibility.

link.springer.com/article/10.1007/s11357-025-02080-z
Infographic titled “Association Between Cagemate Number and Risk of Death in Mice: A Time-Varying Covariate Analysis Using Cox Frailty Models.” Left panel (“Study Design”) shows same-sex mouse housing with a median of three mice per cage, no reassignment after a cagemate’s death, and a study population of 2,635 mice across three research sites. Center panel (“Survival Analysis / Results”) describes Cox frailty models with random effects for site and cage and fixed effects for sex, treatment, and number of cagemates. A line graph shows mortality risk versus number of living cagemates: a blue line (females) slopes downward, indicating lower mortality with higher cage density, while an orange line (males) remains relatively flat, indicating no major change. Right panel (“Considerations”) highlights that social environment influences longevity, particularly in females, and emphasizes the need to consider social housing dynamics in experimental design and animal welfare protocols.

A new article explores 5️⃣ lessons from global approaches to animal use in #MedEd:

💲 Cost & scalability
🐖 Moral, religious, & cultural factors
🌏 Global collaboration

Authored by my colleague, Samuel Pons, & Dr. John Pawlowski of @bidmcreseach.bsky.social:
doi.org/10.1007/s441...

#MedSky #SurgSky
The image has an orange background with a white text box in the center. The background features a faint globe outline. Inside the quote box in blue font is: "Some German and Italian schools have policies in place for conscientious objection to animal use in medical training. This exemption allows students to refuse to participate in trainings without fear that doing so will formally impact their ability to pass their course... [A]nimal alternatives should be considered as a means to increase accessibility and prevent students from missing out on learning key skills, as there are few, if any, moral, cultural, or religious beliefs that would limit a student’s ability to participate in medical training using nonanimal alternatives."

Cara S. Swain, PhD critiques inconsistent use of “validity” & “fidelity” in #MedEd research, urging conceptual rigor for simulation models.

A stronger evidence base can help us determine which models to adopt, refine, or transition away from.

The image is divided vertically into two halves. Center title in white states: "ASSESSING SURGICAL SIMULATION MODELS." A graphic of a pair of scissors is next to it. Blue left side: A black pig graphic and the word "FIDELITY" are on the upper left side. Below, a quote in black reads: "[A]n interpretation of how faithful a simulator is in comparison to reality. However, it is not a binary high-low concept, as used in many scientific publications, but a fluid attribute..." An orange squiggly line runs in the bottom left side. Orange right side: A black pig graphic and the word "VALIDITY" are in the bottom right. Above, a quote in black text reads: "[T]he focus of validity is not on faithful replication of reality, but whether the simulator is actually teaching what it is intended to teach." At the bottom of the image, inside a white box, there is a citation for the linked paper.

A quote in black on a white background reads: “Compared to other lab models, such as cancer-derived cell lines or animal models, HNOs [human nose organoids] offer several advantages. They very closely resemble real human nasal tissue, can be used for multiple experiments over years, and reflect the genetic diversity of human donors.” Above the quote to the left is a quote symbol in green with a short green line below and to the right.

FDA Modernization Act 3.0 passed the U.S. Senate, bringing it closer to law and reinforcing a shift to modern, science-driven nonclinical testing. By removing outdated animal-testing language, it supports robust, human-relevant NAMs. We are excited to use this momentum at InSphero in the new year! 🚀
