Unraveling the brain mechanisms behind social hierarchies in mice

Social hierarchies are everywhere-think of high school dramas, where the athletes are portrayed as most popular, or large companies, where the CEO makes the important decisions.

DNA nanosprings enable precise detection of KIF1A mutations in nerve cells

Cells all require the transport of materials to maintain their function. In nerve cells, a tiny motor made of protein called KIF1A is responsible for that. Mutations in this protein can lead to neurological disorders, including difficulties in walking, intellectual impairment and nerve degradation.

Study links brain waves to misremembering of negative, irrelevant information

A good night's sleep has long been understood to help us consolidate new memories, but we don't understand how. Associations with negative feelings like fear or stress can improve recall, but intentionally trying to remember can also be effective. But these two mechanisms are very different - one involuntary, one deliberate.

IASLC proposes new tumor budding-based grading system for lung squamous cell carcinoma

Invasive lung squamous cell carcinoma (LUSC) accounts for approximately one-quarter of all lung cancers, but therapeutic options for LUSC remain limited, primarily due to the absence of well-defined, targetable molecular alterations.

'Good' gut microbe found to support fetal growth and reduce pregnancy risks

Research led by the University of Cambridge has found the first clear evidence that the 'good' gut bacteria Bifidobacterium breve in pregnant mothers regulates the placenta's production of hormones critical for a healthy pregnancy.

Microplastics can alter the human gut microbiome, research shows

New research presented today at UEG Week 2025 shows that microplastics – plastic particles smaller than 5mm commonly found in the environment – can alter the human gut microbiome, with some changes resembling patterns linked to depression and colorectal cancer.
