'Two-in-one' RNA molecule can simultaneously turn off two difficult-to-target cancer-related genes

University of North Carolina Lineberger Comprehensive Cancer Center researchers have developed a "two-in-one" molecule that can simultaneously turn off two notoriously difficult-to-target cancer-related genes, KRAS and MYC, as well as directly deliver drugs to tumors that express these genes.

New treatment approach developed to prevent lupus nephritis

At the time when patients with lupus, or systemic lupus erythematosus (SLE), are diagnosed, approximately 15% to 30% will already have the inflammation-caused kidney disease lupus nephritis, which compromises kidney function and can lead to kidney failure.

New insights reveal how sugar metabolism protects neurons from degeneration

Unlike most cells in the human body, neurons-the functional cells of our nervous system-cannot typically replace themselves with healthy copies after being damaged.

Natural brain rhythms control stress hormone levels and alertness

Ōtākou Whakaihu Waka-led research has found stress-controlling brain cells switch on and off in a steady rhythm about once every hour – even when nothing stressful is happening.

Leptin could offer alternative to insulin for managing type 1 diabetes complication

More than a decade ago, researchers found that an acute complication of type 1 diabetes, diabetic ketoacidosis (DKA), can be resolved with the hormone leptin, even in the absence of insulin.

New brainwave marker identified for Alzheimer’s detection

Using a custom-built tool to analyze electrical activity from neurons, researchers at Brown University have identified a brain-based biomarker that could be used to predict whether mild cognitive impairment will develop into Alzheimer's disease.

Sleep strengthens motor learning through targeted brain rhythms

When faced with difficult tasks, sometimes people hit a mental wall and make the decision to "sleep on it." Returning to the task after sleeping, they often perform better. Why? Rhythmic brain activity during sleep transforms task-related information into stronger, longer-term memory.

Mouth and gut microbes talk to each other - here’s why it matters for disease

Researchers reviewed nearly 250 studies to uncover how the oral and gut microbiomes communicate through multiple pathways, influencing the risk of diseases such as IBD, colorectal cancer, and cardiovascular disorders. The review highlights that maintaining oral health and dietary habits is crucial for overall systemic wellbeing.

Impulsivity shapes diet and gut bacteria in healthy adults, study finds

Impulsivity in healthy adults is linked to unhealthy dietary choices, such as higher intake of alcohol and sugary drinks and lower fiber consumption. These dietary behaviors, in turn, are associated with changes in specific gut bacterial genera, highlighting an indirect pathway between personality traits and the gut microbiome.

HIV trial points to semaglutide as a new anti-aging contender

Once-weekly semaglutide significantly slowed epigenetic aging in adults with HIV-associated lipohypertrophy, as measured by multiple DNA methylation clocks in a randomized controlled trial. These exploratory findings suggest GLP-1 receptor agonists could impact biological aging but require further validation in broader populations.

UCLA study shows stem cells can be reprogrammed to fight cancer

In a first-of-its-kind clinical trial, UCLA scientists have shown it's possible to reprogram a patient's blood-forming stem cells to generate a continuous supply of functional T cells, the immune system's most powerful cancer-killing agents.

Weight loss doubles when eating minimally processed foods over ultra-processed alternatives

When given nutritionally matched diets, participants lost twice as much weight eating minimally processed foods compared to ultra-processed foods, suggesting that cutting down on processing could help to sustain a healthy weight long term, finds a new clinical trial led by researchers at UCL and UCLH.

Metformin’s blood sugar control starts in the brain, not just the liver, study finds

Low, clinically relevant doses of metformin lower blood glucose by inhibiting the Rap1 protein in specific neurons of the hypothalamus, revealing a brain-first mechanism. This action is essential for metformin’s effect at therapeutic doses and highlights new directions for diabetes treatment.
