New model reveals how disability caregiving reshapes parents' lives over decades
Researchers are sounding the alarm on the long-term impact of caring for children with developmental disabilities in the absence of proper societal supports across the life course. A new conceptual study, published in the Journal of Family Theory & Review, proposes a new model fo
After amyloid plaques form, tau and alpha-synuclein pathology rises in mice
After amyloid plaques form, tau and alpha-synuclein pathology rises in mice
The aging brain frequently harbors multiple protein pathologies that contribute to Alzheimer's, Parkinson's and other neurodegenerative diseases. But how do these problematic proteins interact with each other, and could these interactions inform future therapies? Researchers at T
In São Paulo, Brazil, the expansion of bike lanes and parks encourages residents to cycle
According to a study that analyzed the behavior of 1,500 São Paulo residents between 2014 and 2024, the implementation of new bike lanes, parks and other public facilities in the Brazilian city has encouraged transportation-related physical activity and promoted public health ben

Gut bacteria linked to malnutrition may pass to younger generations
A study led by researchers at Washington University School of Medicine in St. Louis suggests that an intestinal disorder linked to malnutrition and stunted growth may be transmitted from one generation to the next via the small intestinal microbiome. Analyzing mouse models of the
Liver-directed gene therapy shows preclinical efficacy for severe inherited metabolic diso
Genespire, in collaboration with researchers at the San Raffaele Telethon Institute for Gene Therapy (SR-TIGET), announced the publication of preclinical data supporting the potential of its liver-directed immune-shielded lentiviral gene therapy approach to treat methylmalonic ac
New approach to gene correction for iron storage disease
New approach to gene correction for iron storage disease
Hereditary primary hemochromatosis is caused by a single faulty building block in a gene. This leads to iron overload, which can have serious consequences for organs and joints. In preclinical studies, researchers have already successfully treated this genetic defect using a targ
Researchers uncover hormone link between gut and brain in anorexia nervosa
Researchers uncover hormone link between gut and brain in anorexia nervosa
People with anorexia nervosa have unusually high levels of a hormone called LEAP2 in their blood when they are in the acute phase of the disorder, according to research presented at the Federation of European Neuroscience Societies (FENS) Forum 2026. Patients with the highest lev
Psychedelic drug screen in mice may overlook stress and brain changes
Over the past decades, some medical researchers and neuroscientists have been exploring the possible therapeutic effects of psychedelic compounds, such as lysergic acid diethylamide (LSD) and psilocybin. These are substances that act on serotonin receptors in the brain and can al
Researchers expand plasmonic liquid biopsy platform to early-stage colorectal cancer
Researchers expand plasmonic liquid biopsy platform to early-stage colorectal cancer
A research team led by Minyoung Lee and Sunggyu Park of The Korea Institute of Materials Science (KIMS) Bio & Health Materials Research Division has developed a plasmonic-based liquid biopsy platform capable of ultrasensitive detection of KRAS mutations in the blood and urine of

Epigenetic mapping provides deeper insight into leukemia
Researchers at Karolinska Institutet in Sweden and Kyoto University in Japan have identified new subgroups of the blood cancer acute myeloid leukemia. The study, published in the journal Nature, shows that changes in the regulation of genes within cells can help explain variation
Hidden pathway drives COVID-19 infection, triggers damaging inflammation in the lungs
Hidden pathway drives COVID-19 infection, triggers damaging inflammation in the lungs
New research has uncovered a hidden pathway that allows COVID-19 to infect the immune system and trigger damaging inflammation in the lungs. The study by La Trobe University and WEHI researchers found SARS-CoV-2, the virus that causes COVID-19, can hide inside tiny fragments of d
New mechanism explains how nerve cells form one long output branch
New mechanism explains how nerve cells form one long output branch
DZNE researchers have uncovered a mechanism that determines why a neuron usually forms a single, long extension called an "axon"—a phenomenon that is fundamental to how our brain functions. Contrary to the common view that external cues drive axon formation, the team of scientist
