Study highlights key role of non-contractile cardiac cells in persistent atrial fibrillation

Atrial fibrillation (AF), the most common chronic cardiac arrhythmia in clinical practice, is very challenging to treat once it becomes persistent, after which spontaneous return to normal rhythm becomes highly unlikely.

Boosting good immune cells can help fight insulin resistance and diabetes

Scientists at the University of Pittsburgh School of Medicine discovered a surprising new way the body can fight insulin resistance and diabetes – by boosting a special type of "good" immune cell in fat tissue.

Early cognitive stimulation preserves memory in Alzheimer’s

A team from the Institute of Neurosciences of the University of Barcelona (UBneuro) has discovered that early and sustained cognitive stimulation can help preserve brain connectivity and memory in Alzheimer's disease, even in advanced stages of the pathology.

Researchers identify a previously unknown cellular barrier in the brain

VIB and Ghent University researchers have identified and characterized a previously unknown cellular barrier in the brain, which sheds new light on how the brain is protected from the rest of the body.

Aligning overnight fasting with sleep improves heart health

A new Northwestern Medicine study has personalized overnight fasting by aligning it with individuals' circadian sleep-wake rhythm - an important regulator of cardiovascular and metabolic function - without changing their caloric intake.

SLAMF6 discovery offers hope for non-responding cancer patients

Cancer researchers working on immunotherapies have made a big discovery: SLAMF6, a molecule on the surface of immune cells that prevents T cells from effectively attacking tumors – and, in mice, they've found a way to neutralize it.

Blood omics data forecasts trauma outcomes with high accuracy

Researchers at the University of Colorado Anschutz have developed a way to predict how trauma patients will recover, days before complications come to fruition, by analyzing the molecules in their blood.

Visual experience shapes feedback wiring in the brain

Visual experience triggers the formation of a web of neural connections in different brain areas in order to make sense of the world – and in particular, of feedback connections, which send information from higher-level visual centres back to earlier ones.

Neuron lattice structure may guard against neurodegeneration

Brain cells are constantly swallowing material from the fluid that surrounds them - signaling molecules, nutrients, even pieces of their own surfaces - in a process known as endocytosis that is essential for learning, memory and basic neural upkeep.

Nanovaccine design boosts immune attack on HPV tumors

Throughout the past decade, Northwestern University scientists have uncovered a striking principle of vaccine design: Performance depends not only on vaccine components but also on vaccine structure.

Study uncovers immune trigger behind vaccine-induced immune thrombocytopenia and thrombosis

A global research collaboration of scientists from McMaster University (Canada), Flinders University (Australia) and Universitätsmedizin Greifswald (Germany) uncovered why a small number of people developed dangerous blood clots after either receiving certain COVID‑19 vaccines or experiencing a natural adenovirus infection, and the answer lies in an unexpected case of misdirected targeting by the immune system.

Advanced three-dimensional imaging maps vascular amyloid spread

Researchers at Niigata University have used advanced three-dimensional (3D) imaging to reveal how amyloid β (Aβ) deposits spread along blood vessels in the human brain in cerebral amyloid angiopathy (CAA).

Can aquaculture reduce global malnutrition or is nutrient trade widening inequality?

Global aquaculture produces substantial essential nutrients, but international trade patterns often shift these nutrients away from nutritionally vulnerable countries. Modelling suggests alternative trade and fishmeal use strategies could improve micronutrient equity while highlighting important food system trade-offs.

Alzheimer’s plaques decline after CAR-T immune cell treatment in preclinical study

Researchers engineered CD4+ chimeric antigen receptor T cells targeting fibrillar amyloid beta and tested them in a mouse Alzheimer model. The preclinical study showed reduced amyloid pathology and altered neuroimmune responses, supporting CAR-T immunotherapy as a potential future Alzheimer strategy.
