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.

Study reveals hidden bacterial role in the formation of most kidney stones

In an unexpected finding, a UCLA-led team has discovered that bacteria are present inside the most common type of kidney stone, revealing a previously unrecognized component involved in their formation.

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.

Tiny plastic particles may interfere with brain processes implicated in Parkinson’s disease

Micro- and nanoplastics are increasingly detected in human tissues, including the brain, and experimental evidence suggests they can interact with biological pathways central to Parkinson’s disease pathology. This review synthesises mechanistic data indicating that plastic particles may influence protein aggregation, neuroinflammation, mitochondrial dysfunction, and the gut–brain axis, while emphasising the need for prospective human studies.

COVID-19 severity is linked to changes in mitochondrial DNA methylation

This study examined mitochondrial and nuclear-encoded mitochondrial DNA methylation in Indian patients with severe COVID-19 and found region-specific differential methylation linked to disease severity. Pathway analyses and protein assays implicated disrupted mitochondrial metabolism and dynamics, suggesting a role for mitochondrial epigenetic regulation in COVID-19 pathophysiology.

Interferon response key to fighting rhinovirus infections in nasal passages

When a rhinovirus, the most frequent cause of the common cold, infects the lining of our nasal passages, our cells work together to fight the virus by triggering an arsenal of antiviral defenses.

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.

Study reveals how antibiotic resistant bacteria delay chronic wound healing

An international team of scientists, led by Nanyang Technological University, Singapore (NTU Singapore), has discovered a new way that could speed up the healing of chronic wounds infected by antibiotic-resistant bacteria.

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.
