Researchers in Germany identified seven types of barriers that can make communicating with the public about animal research difficult, highlighting the challenges for researchers and…

Researchers in Germany developed magnetic nanoparticles that improved movement in mice with Parkinson’s symptoms.   Parkinson’s disease affects around 10 million people worldwide and is caused by the…

Researchers in the US have discovered that a diet enriched with a single amino acid protected mice against intestinal cancer and infections, including the flu and COVID-19.  Changes in…

Researchers in Ireland have developed an implant that releases therapeutic agents and monitors tumour response in mice with ovarian cancer, potentially improving how this cancer is treated.  Ovarian…

Researchers in Ireland showed that a dietary supplement made from baker’s yeast boosted the body’s ability to fight cancer and slowed tumour growth in obese mice.  Obesity weakens the immune system,…

A study in Canada, combining mice and bioinformatics, unveiled how immune cells form life-threatening clusters during sepsis and pointed to a drug that could improve treatment.  Sepsis is an…
