A scaffolded vaccine approach for broader influenza protection

Most people who get the seasonal influenza vaccine – which contains strains of viruses from distinct virus subtypes – mount a strong immune response to one strain, leaving them vulnerable to infection by the others, and researchers have long wondered what impacts such variable responses more – host genetics or prior exposure to virus strains.

A new link between brain health and mitochondrial function

New findings in mice have uncovered a crucial mechanism linking neuronal activity to mitochondrial function, researchers report, revealing a potential pathway to combat age-related cognitive decline. Mitochondria play a pivotal role in meeting the dynamic energy demands of neuronal activity, producing adenosine triphosphate (ATP) primarily via oxidative phosphorylation (OXPHOS).

Unleashing the potential of biological timekeeping

Living organisms monitor time – and react to it – in many different ways, from detecting light and sound in microseconds to responding physiologically in pre-programmed ways, via their daily sleep cycle, monthly menstrual cycle, or to changes in the seasons.

SMART software offers new solution for modeling cell-signaling networks

Researchers at University of California San Diego have developed and tested a new software package, called Spatial Modeling Algorithms for Reactions and Transport (SMART), that can realistically simulate cell-signaling networks - the complex systems of molecular interactions that allow cells to respond to diverse cues from their environment.

Study uncovers a previously unknown genetic link to autism spectrum disorder

New research published in The American Journal of Human Genetics has identified a previously unknown genetic link to autism spectrum disorder (ASD). The study found that variants in the DDX53 gene contribute to ASD, providing new insights into the genetic underpinnings of the condition.

Syphilis family traced to Pre-Columbian Americas

In spring 1495, the Italian campaign of Charles VIII of France was interrupted by an intense outbreak of an apparently unknown illness – a disease of high mortality that quickly engulfed the whole of Europe and left its survivors with life changing impairments to their bodies and minds.

Study reveals link between dyslexia genes and brain structure

Dyslexia is a common learning difficulty in which genes often play a role. How do genes associated with dyslexia relate to brain structure in the general population? In a large-scale study published in Science Advances, a team of scientists led by the Max Planck Institute for Psycholinguistics in Nijmegen found that genetic variants that increase the chance of dyslexia were associated with differences in brain areas involved in motor coordination, vision, and language.

New approach in fighting leukemia with double-modified natural killer cells

Various forms of blood cancer exist – all of which are grouped together under the term leukemia. One common form of leukemia is acute myeloid leukemia (AML), characterized by a degradation of early blood cell precursors, i.e. stem cells and the precursor cells that develop from them.

Genetic testing improves care for pediatric neurodevelopmental disorders

Adding genetic testing to the evaluation of pediatric patients with neurodevelopmental disorders (NDD) resulted in more individualized care, including changes in medication, referrals to clinical trials or specialists, and surveillance for potential medical issues, according to a new UCLA Health study.
