Researchers explore the link between tau levels and depressive symptoms in older people

During typical aging and Alzheimer's disease progression, higher levels of a protein called tau are associated with more depressive symptoms.

New statistical framework untangles genetic and environmental autism risk

A powerful new research tool from a University of Virginia School of Medicine scientist and colleagues is set to advance our understanding of how genetics and environment contribute to autism risk.

Short workouts or naps protect memory after sleep deprivation

A short workout or a nap can help protect memory after a sleepless night, a McGill University-led study has found.

Targeting cyclin-dependent kinases offers new pathways for cancer therapy

Cancer is the second leading cause of death in Germany. In the search for new therapeutic approaches that target the uncontrolled growth of tumor cells, a class of enzymes known as cyclin-dependent kinases (CDKs) has come into focus.

Older brains' language processing network remains resilient to aging

As people age, many cognitive functions tend to decline. Brain scanning studies have revealed corresponding changes in the function of a brain network that is involved in many of these cognitive functions, including working memory and problem-solving.

Review uncovers how tryptophan metabolism affects female reproductive health

In recent years, issues concerning female reproductive health have become a global challenge that cannot be ignored.

Yeast-based nanoparticle vaccine could make annual flu shots obsolete

The world mostly relies on an 80-year-old method for producing flu vaccines from chicken eggs - a slow, costly process that struggles to quickly adapt to new, mutant strains.

Book reframes pregnancy loss as a natural trial-and-error process

According to a new book from University of Illinois Urbana-Champaign anthropology professor Kate Clancy, pregnancy is necessarily fraught, involving a series of tests of egg, embryo and reproductive system viability, with potential losses at every stage.

Fruit fly brain inspires energy-efficient scent classification algorithm

In the animal kingdom, energy conservation is essential for survival. That's why our brains have evolved to be extremely energy and resource efficient at storing and processing information.

Nanoparticle vaccine offers long-lasting protection against multiple flu strains

A new, nanoparticle vaccine could one day grant patients immunity to the flu with fewer trips to the doctor and without health officials correctly guessing which flu strains will become dominant each year.

Disrupted brain-immune signaling may help drive neurodegeneration

A Cell perspective argues that neurodegeneration can emerge from disrupted communication between neural and immune networks, with peripheral immunity, microglia, and gene-regulatory programs all shaping disease processes. The authors propose that restoring immune homeostasis and recalibrating neuroimmune circuits could create new therapeutic and diagnostic opportunities, while emphasizing that many mechanisms remain unresolved in humans.

Researchers followed children for a decade to see whether screen time really mattered

A large Scottish birth cohort found that screen use showed limited and inconsistent associations with children’s emotional, behavioral, and social development from ages 5 to 15. Very high gaming in adolescence stood out, while several other associations weakened after adjustment, sensitivity analyses, or correction for multiple testing.

A striking immune cell pattern emerges around a person’s 100th birthday

Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

Scientists uncover tRNA changes driving Chagas parasite transformation

The Chagas disease parasite (Trypanosoma cruzi) undergoes a major transformation throughout its life cycle in order to infect humans and other mammals.

Deliverome project maps cell surface proteins for better drug delivery

For a new drug to work in the human body, it must make its way to the exact cell type where it's needed and then, in many cases, get inside the cells.

New 3D mapping technology reveals how hair follicles form over time

In a new research report, scientists at Johns Hopkins Medicine say they have developed a technology that allows them to capture a 3D molecular "snapshot" of hundreds of hair follicles as they develop and then reconstruct the fourth dimension - time - to effectively create a stop-motion animation of how this organ forms.

UC Berkeley researchers find new potential treatment for obesity and diabetes

Over the past five years, medications called GLP-1s have revolutionized the treatment of metabolic disorders like obesity, diabetes and fatty liver diseases.

Study provides a more nuanced picture of biological mechanisms linked to autism

How does autism manifest in the brain? Researchers from the University of Southern Denmark and Odense University Hospital have investigated this question in a new study involving 60 adults.

Neurogenesis stalls in the brains of adults with major depressive disorder, study shows

Most of our brain's 100 billion neurons are created before we're born, but the trickle of neurons created in the adult brain hippocampus could be instrumental in preventing depression, suggest findings from a new study by researchers at Columbia University Vagelos College of Physicians and Surgeons.

Oxford study identifies brain mechanisms behind our sense of control

A study led by the University of Oxford has identified the brain mechanisms that help us work out whether the consequences we experience are caused by our own actions or by circumstances beyond our control.
