Decoding the purpose of fetal yawns in the womb

Even in the womb, where all oxygen is provided by the parental placenta, fetuses can-and do-yawn. More yawns during observation were associated with a lower weight at birth-potentially indicating mild fetal stress in the womb, according to a study published February 25, 2026 in the open-access journal PLOS One by Damiano Menin, of the Università degli Studi di Ferrara in Italy, and colleagues.

Morning chronotype and exercise associated with reduced ALS risk

Being an early bird, also called a morning person, and being more physically active are associated with lower risks of amyotrophic lateral sclerosis (ALS), according to a preliminary study released February 25, 2026, that will be presented at the American Academy of Neurology's 78th Annual Meeting taking place April 18-22, 2026, in Chicago and online.

Brain rhythms may explain modern digital distraction susceptibility

Scientists may have new answers to why pop-ups or notifications grab our attention. Turns out our attention is on a cycle, shifting seven to ten times per second.

Could a rare gene variant help reduce smoking? New study suggests it might

An exome-wide association study of nearly 38,000 smokers from the Mexico City Prospective Study identified rare coding variants in CHRNB3 that are associated with substantially fewer cigarettes smoked per day. Cross-ancestry analyses in European and East Asian datasets support a role for the β3 nicotinic receptor subunit in modulating smoking intensity.

Implanted cuff electrodes could trigger unintended nerve stimulation during MRI

A University of Houston engineering professor is warning that implanted cuff electrodes – widely used in therapy for epilepsy, depression and inflammatory disorders – could trigger unintended nerve stimulation for patients undergoing an MRI scan.

Study reveals how meal skipping during teen pregnancy connects to mental health

A cross-sectional study of pregnant adolescents found that skipping meals, screen distraction during eating, and low dairy intake were associated with higher depressive symptom prevalence. Overall dietary diversity showed no significant relationship, and causality could not be established.

Adults with intellectual and developmental disabilities face severe mental health disparities

Adults with intellectual and developmental disabilities, such as autism and Down syndrome, experience substantially higher rates of anxiety and depression than the general population of adults, researchers reported today in JAMA Network Open.

Review: Natural selection can occur on multiple levels of biological organization

The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed down to its offspring.

Screening helps detect colorectal cancer at an early stage

More cases of colorectal cancer are detected at an early stage with screening. This is according to new research based on data from over 278,000 60-year-olds, who were randomly selected to undergo one of two interventions or no screening at all (usual care).

Blood test shows promise in forecasting outcomes for germ cell tumors

Can fragments of tumor DNA in the blood predict whether chemotherapy will be effective? Researchers at the Princess Máxima Center investigated this question together with experts from Italy and Slovakia.

Study examines low-risk cannabis use years after legalization

A new study led by Marie-Pierre Sylvestre, professor at the Université de Montréal School of Public Health, examines cannabis use 4 to 5 years after Canadian legalization by adopting a different perspective: rather than focusing solely on at-risk cases or those associated with problems, it identifies the socio-demographic, mental health, and lifestyle profiles of those who present a low risk of cannabis use disorder (CUD).

Loose clothing sensors enhance clinical movement tracking

Loose-fitting e-textiles may offer superior motion tracking capabilities, enhancing recognition accuracy and prediction over conventional rigid sensors.

Intermittent calorie restriction proves as effective as daily calorie cuts for type 2 diabetes

A post-hoc analysis of two clinical trials compared continuous calorie restriction with early time-restricted eating in adults with type 2 diabetes and overweight or obesity over three months. Both approaches improved weight, body composition, and metabolic health, with no clear superiority except for lower dropout with intermittent restriction.

Short health ads reduce junk food cravings

A new Edith Cowan University (ECU) study has found advertisements that encourage healthy choices can reduce cravings and intentions to consume unhealthy foods, and in some cases a 15-second message may be more effective than traditional 30-second commercials.

Study links microbe-rich diets with better insulin and cholesterol markers

This exploratory Australian study developed a database to estimate live microbe content in foods and examined associations with cardiometabolic health indicators in adults. Higher intake of foods estimated to contain live microbes was linked with favourable markers such as higher HDL cholesterol and lower BMI, insulin, and waist circumference, although causality cannot be inferred.

Sleep loss triggers brain fluid pulses that impair attention, study finds

Sleep deprivation causes attentional lapses that coincide with coordinated changes in brain activity, pupil diameter, blood flow, and cerebrospinal fluid dynamics. These findings suggest attention failures reflect a transient brain–body state linked to sleep pressure rather than isolated neural errors.
