LEAP2 hormone may predict anorexia nervosa relapse risk

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 today (Thursday) at the Federation of European Neuroscience Societies (FENS) Forum 2026.

Global groundwater maps reveal hidden manganese risk for 220 million people

Machine learning maps suggest that about 180 to 220 million people may rely on untreated groundwater with manganese above the WHO’s updated 80 µg/L guideline. The study places manganese exposure on a similar global scale to arsenic and fluoride, yet shows it remains far less visible in groundwater monitoring.

Hypoxia therapy shows promise for treating mitochondrial brain disorders

Oxygen isn't always a good thing. Of course, people-and most organisms-cannot live without it. But oxygen can also be quite toxic and lead to profound health consequences.

Cosmetic microneedles deliver actives where creams struggle

This review shows how microneedle-based cosmetic systems bypass the stratum corneum to deliver poorly penetrating actives, including peptides, retinoids, vitamins, niacinamide, hyaluronic acid, and hair-growth compounds, into viable skin layers.

Early detection of congenital cerebral ventriculomegaly can help prevent developmental disabilities

Early detection and treatment of congenital cerebral ventriculomegaly (CCV)-when a fetus's fluid-filled brain ventricles swell due to a condition called hydrocephalus-can help clinicians prevent developmental or neurological disabilities in affected infants.

Tears may reveal important clues about a person's neurological health

A few tears may someday reveal important clues about a person's neurological health. Researchers reporting in ACS Omega developed a low-cost electrochemical sensor designed to detect dopamine, a neurotransmitter involved in movement, learning, motivation, and emotional regulation.

Review highlights pregnancy and miscarriage rates among transmasculine people

A recent review of published research provides some evidence that a small but noteworthy minority of transmasculine people (trans, nonbinary, and other gender expansive people who were assigned female at birth) have pregnancies (6%–9%) and children (4%–9%), including after transition.

New review shows why antidepressants often fail in Alzheimer’s and Parkinson’s depression

A Molecular Psychiatry review shows that depression in Alzheimer’s and Parkinson’s disease may reflect disease-specific molecular, neurotransmitter, inflammatory, and circuit-level disruptions rather than standard depression biology alone. It argues that broad antidepressants often show limited efficacy in these patients and that future trials should use biomarkers, neuroimaging, and symptom profiling to guide targeted treatments.

Study reveals why patients with rare leukemia develop resistance to tagraxofusp

Researchers at The University of Texas MD Anderson Cancer Center have identified why some patients with a rare type of leukemia, called blastic plasmacytoid dendritic cell neoplasm (BPDCN), eventually develop resistance to tagraxofusp, the first Food and Drug Administration-approved treatment for this disease.
