Research from the US shows that artificial intelligence (AI) can accurately predict how proteins interact with one another.

A study in the US used pigs as a model for a common liver complication caused by intravenous feeding in premature babies. 

Research from the US shows that a new lymph-node-on-a-chip can replicate age-dependent immune responses to cancer vaccines, providing a more accurate testing platform. 

A US study has discovered that African chimpanzees routinely consume alcohol naturally present in overripe fruit that, given the size of their bodies, would be equivalent to having two drinks a day, suggesting that human addiction to alcohol has an evolutionary root.

In November, EARA advanced its mission on three major international stages — the AALAS National Meeting (Long Beach, USA), the Society for Neuroscience Annual Meeting (San Diego, USA) and the SECAL National Congress (Bilbao, Spain) — putting patient engagement, openness and responsible communication at the centre of global discussions on animal research. 

A US study has developed a technology using rats and pigs that can stimulate the immune system to heal the heart after a heart attack.  

A recent opinion article in The Transmitter by US neuroscientists Cory Miller, from the University of California, San Diego, J. Anthony Movshon, from New York University, and Doris Tsao, from the University of California, Berkeley, raised concerns over the recent policy changes in Europe and the US that would scale back animal research – including in primates.  

Scientists in the US have discovered how the brain can recover from a distraction to return to the task at hand, in a study using monkeys.  

Researchers in the US have identified a previously unknown brain circuit that controls how mice respond to sudden threats and recover from fear. 

Two comment articles with opposite perspectives about the role of animals in biomedical research have been featured in Nature.

Researchers in the US have developed lab-grown kidneys (organoids) that, for the first time, could produce urine when transplanted into mice.  

Researchers in the US have found that amyloid beta, a hallmark in Alzheimer’s, can strengthen immune responses and reduce tumour growth in mice. 

The 2025 Nobel Prize in Physiology or Medicine was awarded to three researchers — Shimon Sakaguchi, Mary E. Brunkow and Fred Ramsdell — for discovering how the immune system is kept in check, based on studies in mice.

Scientists in the US, in a study using gerbils, have kept tissue from a crucial inner ear organ alive outside the body, creating an unprecedented system that could allow researchers to understand how hearing works and test potential treatments for hearing loss. 

US researchers have developed the first lung organ-on-a-chip with a working immune system, a development that could significantly improve the ability to mimic the living organ and model disease.

A prominent gene therapy company has announced a groundbreaking therapy for Huntington’s disease that slowed disease progression by 75% in human clinical trials.

A new artificial intelligence tool, developed in the US, helps researchers plan and carry out experiments using CRISPR, the widely used gene-editing technology. 

US scientists have developed a new method that turns the mouse scalp transparent, making it possible to image the living brain during its development. 

US researchers have mapped the formation of the lifetime supply of eggs in a study using monkeys, which could inform the study of ovarian diseases and advance treatments for infertility and hormonal disorders. 

Researchers in the US used artificial intelligence to discover two new antibiotics that can clear superbugs in mice infected with MRSA and drug-resistant gonorrhoea.
