Retina vascular fingerprint offers non-invasive way to predict stroke risk

A vascular 'fingerprint' on the light sensitive tissue layer at the back of the eye-the retina-can predict a person's risk of stroke as accurately as traditional risk factors alone, but without the need for multiple invasive lab tests, finds research published online in the journal Heart.

Inflammasome protects stem cells from becoming cancerous

A group of immune proteins called the inflammasome can help prevent blood stem cells from becoming malignant by removing certain receptors from their surfaces and blocking cancer gene activity, according to a preclinical study by Weill Cornell Medicine investigators.

Doctors, nurses press ahead as wildfires strain Los Angeles’ health care

The rapidly spreading wildfires that have transformed much of Los Angeles County into a raging hellscape are not only upending the lives of tens of thousands of residents and business owners, but also stressing the region's hospitals, health clinics, first responders, and nursing homes.

Most disease-causing mutations that swap amino acids do so by making proteins less stable

Research shows 60% of missense mutations destabilize proteins, linking protein folding to genetic diseases, including cataracts and neurological disorders.

AI-enhanced algorithm improves diagnosis of REM sleep behavior disorder

A Mount Sinai-led team of researchers has enhanced an artificial intelligence (AI)-powered algorithm to analyze video recordings of clinical sleep tests, ultimately improving accurate diagnosis of a common sleep disorder affecting more than 80 million people worldwide.

Unraveling the molecular mechanisms of disease-causing mutations

Most mutations which cause disease by swapping one amino acid out for another do so by making the protein less stable, according to a massive study of human protein variants published today in the journal Nature. Unstable proteins are more likely to misfold and degrade, causing them to stop working or accumulate in harmful amounts inside cells.

Sleep deprivation inhibits the brain's ability to suppress unwanted memories

A new study has shown that sleep deprivation can inhibit the brain's ability to suppress unwanted memories and intrusive thoughts.

AI analysis reveals optimal follicle sizes for IVF success

During IVF treatment, doctors use ultrasound scans to monitor the size of follicles - small sacs in the ovaries containing eggs - to decide when to give a hormone injection known as the 'trigger' to prepare the eggs for collection and ensure that they are ready to be fertilised with sperm to create embryos.

UCD researchers discover gene mutation linked to vision problems in zebrafish

Researchers in University College Dublin (UCD) have discovered that a mutation in a gene called emc1 causes major vision problems in zebrafish.

AI-based tool identifies subtypes of Type 2 diabetes using glucose monitors

Diabetes has long been lumped into two categories - Type 1, which often appears in childhood, or Type 2, which is associated with obesity and typically develops later in life. But scientists have learned that not all patients with Type 2 diabetes are the same, with some patients varying in body weight, age of onset and other characteristics.

New imaging technique could transform obstructive sleep apnea diagnosis

Obstructive sleep apnea (OSA) is a common sleep disorder characterized by intermittent airway blockages during sleep, leading to disrupted breathing.

Predicting H5N1 disease severity based on T cell responses

New research led by scientists at La Jolla Institute for Immunology (LJI) suggests that many people already have immune cells on "stand by" to fight the H5N1 virus, also known as highly pathogenic avian influenza.

Ancient brain circuit stabilizes gaze during movement in early development

An ancient brain circuit, which enables the eyes to reflexively rotate up as the body tilts down, tunes itself early in life as an animal develops, a new study finds.

Sleep deprivation disrupts brain regions that prevent unwanted memories

The link between poor sleep and mental health problems could be related to deficits in brain regions that keep unwanted thoughts out of mind, according to research from the University of East Anglia (UEA).

Freezing Point Osmometry in Life Science Applications

Osmometry is a method to determine a sample´s osmolality. This is the total number of osmotically active particles solved in a solution. These particles influence the colligative properties of the solution, which include the boiling and freezing point but also the vapor pressure for instance.
