New model reveals how chromosomes reorganize during cell replication

It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.

Gut changes linger years after polyp removal and may signal colorectal cancer risk

Researchers found that women who had undergone colorectal adenoma resection still showed gut microbiome and fecal metabolome alterations an average of about 12 years later. These persistent changes partly resembled colorectal cancer-associated patterns, suggesting that the host-microbiome axis may remain altered along the adenoma-cancer continuum.

Gut microbiota may determine severity of life-threatening sepsis infections

Why do some people recover easily from bacterial infections while others rapidly deteriorate into life-threatening sepsis? According to a new study, the answer may lie not only in the invading pathogen itself, but also in the microorganisms already living inside the gut.

How do everyday spices help protect the heart?

A Nutrition Reviews supplement article reviewed controlled studies showing that culinary spice and herb blends may improve selected cardiometabolic risk markers, including post-meal triglycerides, insulin responses, inflammation, endothelial function, and 24-hour blood pressure. The review also highlighted exploratory evidence that spices and herbs may influence immune-cell activity, circulating phytochemical metabolites, and gut bacterial composition, while emphasizing the need for longer and more diverse studies.

Surface acids found crucial for bacterial shape and growth

Researchers have discovered how acids on the surface of bacteria give these microscopic organisms their characteristic "rod" shape-by keeping an enzyme at bay that would otherwise turn the cylindrical cells into shape-shifting blobs.

Dog daycare outbreak exposes gaps in puppy leptospirosis vaccinations

A 2021 outbreak of leptospirosis that sickened more than 200 dogs in Los Angeles County reveals critical gaps in vaccination practices and raises broader concerns about the spread of the disease between animals and people, according to new research led by the University of California, Davis.

New AI model detects hidden antibiotic resistance genes beyond standard databases

resLens uses genomic language models to detect antibiotic resistance genes from DNA sequences, performing especially well on long-read data and on some ARGs poorly represented in reference databases.

Yoga and meditation show promise for gut health

This systematic review found that yoga and Buddhist meditation were associated with favorable gut microbiota and metabolite profiles in four human studies involving healthy adults. However, because participants largely followed vegetarian or vegan diets and no randomized controlled trials were included, the findings cannot prove that meditation alone reshapes the gut microbiome.

Gum disease pathogen may drive Alzheimer’s through microglial ferroptosis pathway

Alzheimer's disease (AD), the leading cause of dementia, is projected to affect 152 million individuals worldwide by 2050; yet its pathogenesis remains poorly understood and effective treatments are lacking.

AI-engineered p53 superproteins may reshape future cancer therapies

The Oncodarwinian Hypothesis (OdH) proposes a paradigm shift: cancer is not merely a disease but a potential macro‑immunoadaptive response – a self‑replicating algorithm that can be reprogrammed via AI‑based 3D printed p53 superproteins.

Bioinformatics accelerates discovery of marine-derived bioactive therapeutic peptides

Marine organisms have evolved a remarkable arsenal of host-defense peptides under conditions of extreme variability and constant pathogen exposure. Generally defined as short chains of 2 to 20 amino acid residues, these molecules have become a focal point for biomedicine, food science, and materials science.

Internal mutations and microbes may drive a distinct subtype of oral cancer

A new study reveals that many oral cancers are no longer driven by traditional risk factors like smoking or Human papillomavirus infection.

Most Americans misunderstand which sexually transmitted infections have preventive vaccines

While data from the Centers for Disease Control and Prevention (CDC) show that the total number of U.S. cases of three sexually transmitted infections (STIs) declined from 2022-24, infection rates remain 13% higher than a decade ago. CDC provisional data show more than 2.2 million U.S. cases of chlamydia, gonorrhea, and syphilis were reported in 2024.

Bacterial sexually transmitted infections reach highest level in a decade

The latest Annual Epidemiological Reports from ECDC indicate a surge in bacterial sexually transmitted infections (STIs) across Europe.

Common vegetable oil compound shows power to fight dangerous viruses

A common vegetable oil may hold the key to fighting some of the world's most dangerous viruses.

Minimal exposure to modern medicine rapidly alters the human microbiome

Even minimal exposure to modern medicine can rapidly change the human microbiome. In a new study publishing May 20 in the Cell Press journal Cell Reports, researchers reveal that the gut microbes of remote Amazonian Indigenous communities began shifting toward patterns more commonly seen in urban, industrialized populations after only a few medical visits.
