Distinct tau chemical signatures redefine diagnosis across neurodegenerative diseases

Tau protein aggregation is a shared feature in over 20 neurodegenerative diseases (collectively referred to as "tauopathies"). New research led by Boston Children's Hospital challenges the current "one-size-fits-all" approach to diagnosing and treating these tauopathies.

Scientists uncover new mechanism initiating gene transcription

Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from deoxyribonucleic acid (DNA) into ribonucleic acid (RNA) can be initiated.

PFOA exposure disrupts hormone signaling and impairs embryo implantation in mice

A new experimental study has found that perfluorooctanoic acid (PFOA), a widely used industrial chemical, can interfere with key biological processes required for successful embryo implantation, raising concerns about its potential impact on female fertility.

Minimally invasive biopsy enables real-time tracking of amyloid disease progression

Transthyretin amyloidosis (ATTR) is a rare, progressive and highly aggressive degenerative disease. It is caused by the misfolding of a specific protein, leading to its toxic accumulation in the form of filamentous deposits in various organs.

Researchers develop protocol to create functional acinar cells in organoids

Organoids are three-dimensional miniature models of organs, grown in a dish.

Researchers discover how Mycoplasma pneumoniae acquires cholesterol from human hosts

A multidisciplinary team has uncovered a key mechanism that allows the human bacterium Mycoplasma pneumoniae-responsible for atypical pneumonia and other respiratory infections-to obtain cholesterol and other essential lipids directly from the human body.

Scientists reveal how cholera bacteria activate toxin genes in the human gut

Cholera remains a major global public health challenge, with an estimated 1.3 to 4 million cases and tens of thousands of deaths reported worldwide each year.

Scientists identify a molecular switch that controls water flow in the gut

Although constipation and diarrhea may seem like opposite problems, they both hinge on the same underlying issue: how much fluid moves into the gut. These common issues affect millions of people in the U.S. each year, yet scientists have not fully understood what regulates intestinal fluid balance.

Coffee-based staining offers eco-friendly solution for electron microscopy

Researchers at TU Graz have proven that espresso is a favourable alternative to the highly toxic and radioactive uranyl acetate in the analysis of biological samples.

New antibody mechanisms disrupt bacterial adhesion in urinary tract infections

Pathogens can create sticky situations. When microbes invade the body to cause an infection, often one of their first lines of attack is to cling tenaciously to the surfaces of targeted human cells.

Integrated neural probes reveal dopaminergic control of sleep-wake transitions

Understanding the dynamic neural mechanisms of sleep-wake cycles is a major challenge in sleep science and neuroengineering.

Nicotinic acid protects the liver from ischemia-reperfusion injury

In a new study published in Liver Research, a team of researchers in China discovered that nicotinic acid-a common form of vitamin B3-can dramatically reduce liver damage caused by ischemia-reperfusion injury (IRI), a major complication in liver surgery and transplantation.

Label-free polarized light reveals subtle red blood cell deformations

Red blood cells are essential for oxygen transport and immune function in the human body. When these cells become abnormally shaped, they can indicate serious health conditions, including diabetes, malaria, hereditary blood disorders, and vascular diseases.

Scientists capture real-time action of antiviral drugs on herpes

Harvard Medical School researchers have uncovered crucial insights into how an emerging class of antiviral drugs works.

30 Dec 2025

Unlocking sleep-wake secrets with dual brain signal analysis

Understanding the dynamic neural mechanisms of sleep-wake cycles is a major challenge in sleep science and neuroengineering.

Novel cryo-EM findings could revolutionize T cell immunotherapy design

One of the most exciting advances in cancer treatments in the past decade is the development of T cell immunotherapies, in which a patient's own immune system is trained to recognize and attack dangerous cells. Yet a full understanding of how they actually work has eluded researchers.

Cryo-EM reveals NPFFR1 activation and guides novel ligand design

This study investigates the molecular mechanisms underlying ligand recognition, subtype selectivity, and activation of neuropeptide FF receptor 1 (NPFFR1)-a Gi/o-coupled receptor that responds to endogenous RF-amide peptides (RFRP-3 from pro-NPFFB, NPFF from pro-NPFFA) and regulates physiological processes like opioid function, pain, and energy homeostasis.

New research reveals the impact of DNA-histone cross-links on genome stability

DNA–protein cross-links (DPCs) represent a severe form of DNA damage that can disrupt essential chromatin-based processes. Among them, DNA–histone cross-links (DHCs) occur frequently within nucleosomes, yet their structural and functional consequences remain poorly understood due to their instability and low natural abundance.
