New computational tool uses plain language for genetic diagnosis

A new computational tool called MARRVEL-MCP helps researchers move toward genetic diagnoses more efficiently by analyzing and interpreting vast amounts of genetic and biological information using everyday language.

Researchers discover how overpopulation reduces fertility

Scientists have reported it for decades: Overpopulation can impair reproduction.

Swedish study reveals fitness benefits outweigh atrial fibrillation risks

It has previously been shown that young, very fit people have an increased risk of atrial fibrillation.

Scientists discover how vitamin K pathway regulates bone remodeling

Bone is continuously renewed through a process known as bone remodeling, in which osteoblasts (bone-forming cells) build new bone, while osteoclasts (bone-resorbing cells) remove older mineralized tissue.

Uneven grey matter loss serves as a powerful new biomarker for early neurodegeneration

Universitat Oberta de Catalunya Alzheimer's disease begins to weave a web in the brain and remodel neuronal tissue 15 to 20 years before the first symptoms appear. From the time this happens, however, until the disease is diagnosed and, later, enters an advanced phase, it progresses along a continuum of changes to the brain.

New CA19-9 threshold improves pancreatic cancer risk prediction accuracy

A dual-threshold model for measuring the pancreatic tumor marker serum carbohydrate antigen 19-9 (CA19-9) identified patients with pancreatic cancer who had high-risk disease despite having low CA19-9 levels because of a genetic variation that impairs their ability to produce this biomarker.

New vaccine approach targets broad protection against arenavirus infections

Scientists at La Jolla Institute for Immunology (LJI) have discovered that combining key vaccine ingredients could give the body the tools it needs to fight the entire family of arenaviruses with a single vaccine.

GLP-1 drugs may help curb addiction by targeting reward pathways

GLP-1 receptor agonists, already used for Type 2 diabetes and obesity, show promise in reducing alcohol and drug-seeking behaviors through central reward and dopamine-related pathways. Most evidence remains preclinical, with limited early human data, so larger clinical trials are needed before these drugs can be recommended for addiction treatment.

Poor sleep may flag early Alzheimer’s risk in genetically vulnerable older women

Poorer subjective sleep quality was linked to worse visual memory and greater limbic tau burden in older women with higher genetic risk for Alzheimer’s disease. The findings suggest sleep complaints may help identify women at elevated risk for early AD-related brain and cognitive changes, but larger longitudinal studies are needed.

Researchers track genetic changes in Brazil's rare Sabiá virus

The Sabiá virus causes an acute hemorrhagic and neurological syndrome. Four fatal cases have been recorded in the state of São Paulo since 1990.

Scientists link schizophrenia risk gene to early cortical neuron changes

Researchers at King's College London have identified the biological nature and timing of changes in human cortical neurons caused by altering activity of a schizophrenia-associated gene in developing human neurons.

Restoring ADAR2 enzyme reduces metastatic spread in osteosarcoma

Osteosarcoma is the most common primary bone cancer in children, adolescents, and young adults. Although chemotherapy and surgery have improved survival for localized disease, outcomes remain poor when tumors spread to the lungs or return after treatment.

Anti-inflammatory drug tocilizumab shows promise for difficult-to-treat depression

Immunotherapy could be a promising new treatment option for patients with difficult-to-treat depression. This is a key finding from a University of Bristol-led pilot randomised controlled clinical trial, published in JAMA Psychiatry today [20 May].

Researchers uncover new genetic links influencing blood lipid composition

DZNE researchers have generated new insights into how the human genome shapes the chemical composition and concentration of blood lipids.

Women may face greater cognitive impact from dementia risk factors

Researchers from the University of California San Diego School of Medicine found that women not only experience a higher burden of certain modifiable dementia risk factors, but also appear more vulnerable to their effects on cognitive function.

Neutrophils may play unexpected role in schizophrenia development

The most common white blood cells in your body - immune cells called neutrophils - can make a protein nobody knew they were making, Stanford Medicine investigators have discovered.

UC Davis scientists identify protein key to male fertility

The causes of male infertility can be hard to diagnose, with many tests failing to detect genetic defects. Sometimes, infertility doesn't even involve the genes themselves.

Molecular profiling initiative seeks to uncover late breast cancer recurrence mysteries

The ECOG-ACRIN Cancer Research Group (ECOG-ACRIN), in collaboration with the SWOG Cancer Research Network (SWOG), has launched a new initiative to analyze paired original and recurrent tumor specimens from two practice-changing breast cancer clinical trials.

Pregnancy-related disorders may shape offspring heart health into adulthood

Hypertensive disorders in pregnancy may lead to lasting cardiovascular issues in offspring, highlighting the need for improved maternal health strategies.
