Genetic testing can guide safer chemotherapy for gastrointestinal cancer patients

For some patients with gastrointestinal (GI) cancers like colorectal and pancreatic cancer, chemotherapy can cause severe, sometimes life-threatening side effects in those who carry certain genetic variants that can impact how their bodies process the drugs used to treat their disease.

Study sheds light on how early brain wiring lays the foundation for attention skills

A new study by researchers at Simon Fraser University is shedding light on how the brain's wiring in early childhood lays the foundation for attention skills- a key step toward characterizing healthy developmental patterns that could help identify young children at risk for attention-related challenges like ADHD.

Researchers uncover dozens of traits driven by maternal versus paternal genes

Researchers developed a high-accuracy method to infer whether genetic variants come from the mother or father without needing parental genomes, analysing 286,666 UK Biobank participants. They uncovered over 30 parent-of-origin effects on traits from growth and metabolism to diabetes, many showing opposite effects depending on parental source.

AI-powered sweat sensor predicts anxiety before symptoms appear

Researchers have developed Stressomic, a wearable microfluidic biosensor that sequentially measures cortisol, epinephrine, and norepinephrine in sweat at six-minute intervals. The device distinguishes physical from psychological stress and predicts anxiety levels using machine learning.

Scientists link brain lithium loss to early Alzheimer’s changes

Researchers have discovered that naturally occurring lithium in the brain is depleted early in Alzheimer’s disease, especially in the prefrontal cortex, and that restoring physiological levels with lithium orotate in mice can prevent brain damage and memory loss. The findings suggest lithium deficiency may be a modifiable risk factor for Alzheimer’s.

New antibody delivery system boosts Alzheimer's treatment in mice

A newly engineered antibody transport vehicle targeting the transferrin receptor enables enhanced delivery of anti-amyloid antibodies to the brains of mouse models of Alzheimer's disease, researchers report.

KFF Health News' 'What the Health?': Kennedy cancels vaccine funding

Health and Human Services Secretary Robert F. Kennedy Jr.'s announcement that the federal government will cancel nearly $500 million in mRNA research funding is unnerving not only for those who develop vaccines, but also for public health experts who see the technology behind the first covid-19 shots as the nation's best hope to combat a future pandemic.

Copper oxide scaffolds show promise in treating traumatic brain injury

Traumatic brain injury (TBI) remains one of the leading causes of disability worldwide. Recent research has developed a novel electrospun scaffold loaded with copper oxide (CuO@PG), which aims to restore copper homeostasis and modulate inflammation in TBI.
