UNC-Chapel Hill researchers develop revolutionary heart model: A breakthrough with potential to transform cardiac care and research

Researchers at UNC-Chapel Hill have developed an innovative computer model of blood flow in the human heart that captures normal heart function and predicts responses to different levels of blood flow. The model has potential applications in medical device design, personalized therapy, and cardiac digital twins.

Moderate expression of CD39 in GPC3-CAR-T cells shows high efficacy against hepatocellular carcinoma

A recent study has identified the pivotal role of CD39 expression in modulating CAR-T cell function. Moderate CD39 expression levels displayed superior antitumor activity compared to those with high or low CD39 levels. The combination strategy of mdivi-1 and CD39 knockdown significantly enhanced the antitumor response.

The Arctic is the only ocean that has not seen a drop in legacy persistent organic pollutants decades after global regulations, says new Concordia study

A new study published in Science Advances found that the Arctic Ocean has seen a sharp rise in legacy persistent organic pollutants (POPs) decades after global regulations were put in place. POPs, which are toxic and bioaccumulative, pose potential dangers to animals and people in the fragile ecosystem's food web.

Students’ challenges in general upper secondary education should be better acknowledged – school burnout can be prevented with the right measures

A recent study found that exhaustion, cynicism, and inadequacy are interconnected dimensions of school burnout. Students who were emotionally engaged in their studies experienced less exhaustion and feelings of inadequacy. Effective support measures should be targeted to prevent burnout in general upper secondary education.

New study uncovers evolutionary roots of conspicuous consumption

A new study led by Dr. Jim Swaffield challenges the assumption that conspicuous consumption is irrational, instead showing it's driven by an interaction between environmental conditions and one's evolved biology. The researchers found that financial and physical safety conditions can affect the desire for signalling products.

What’s chubby enough for lower disability after stroke?

A recent study published in Topics in Stroke Rehabilitation found that slightly overweight stroke survivors (BMI 22.1-27.5 kg/m²) have a lower risk of sustaining disabilities compared to those with normal weight. The research suggests that a higher-than-normal BMI may be beneficial for recovering from a stroke with less disability.

The heaviest element ever chemically studied — Experiments at GSI/FAIR succeed in determining properties of moscovium and nihonium

Researchers have determined the chemical properties of moscovium and nihonium, which are more reactive than flerovium. The study uses a newly developed setup for chemical separation and detection to observe the very short-lived moscovium-288 and its daughter nihonium-284.
