Neuroscientists uncover a surprising role for "Frazzled" protein in the nervous system of fruit flies

Florida Atlantic University neuroscientists have uncovered a surprising role for a protein named "Frazzled" (known as DCC in mammals) in the nervous system of fruit flies, showing how it helps neurons connect and communicate with lightning speed.

Genetic insights into vestibular system damage from ototoxic drugs

The vestibular system is responsible for the sense of balance in the inner ear. Prolonged use of toxic substances, such as certain antibiotics or anticancer drugs, can damage the hair cells that form part of this system, leading to alterations in balance and other motor skills.

Breakthrough study maps impact of thousands of variants in heart disease gene

An international research consortium co-led by scientists from Vanderbilt University Medical Center, the University of Toronto and University of Pittsburgh has mapped the functional impact of more than 17,000 variants in a major gene associated with the development of premature atherosclerotic heart disease.

Massive cross-ancestry study explains why obesity risks differ around the world

A massive cross-ancestry genetic study involving over 839,000 adults identified 13 genes linked to obesity, including five never before associated with the condition. The findings highlight how global genetic diversity can uncover new biological pathways and potential treatment targets for obesity.

Unlocking memory: The role of epigenetics in memory expression

Our experiences leave traces in the brain, stored in small groups of cells called "engrams". Engrams are thought to hold the information of a memory and are reactivated when we remember, which makes them very interesting to research on memory and age- or trauma-related memory loss.

Fruit flies illuminate the role of Alzheimer's disease risk genes

Scientists have identified hundreds of genes that may increase the risk of developing Alzheimer's disease but the roles these genes play in the brain are poorly understood.

Novel 3D chromosome mapping method can reliably reveal hidden structural variants

Standard laboratory tests can fail to detect many disease-causing DNA changes. Now, a novel 3D chromosome mapping method can reliably reveal these hidden structural variants and lead to new discoveries.

Researchers discover a previously unknown genetic cause for microcephaly

Microcephaly is a congenital malformation that leads to a significantly reduced brain size and is often accompanied by developmental delay.

New software enables real-time pathogen surveillance in the air and environment

Metagenomics is the study of all organisms present in a particular environment, such as soil, water, or the human body. A key part of metagenomic analysis is understanding what species are present (classification), how much of each there is (abundance), and the function of the microorganisms present.

Genetic analysis of blood sample could offer a non-invasive way for early Parkinson’s diagnosis

The genetic analysis of a blood sample could become a tool for the early diagnosis of Parkinson's disease, according to an exploratory study led by researchers from the Miguel Hernández University of Elche (UMH).

Ancient DNA uncovers paratyphoid and relapsing fever among Napoleonic troops

Scientists from the Institut Pasteur have genetically analyzed the remains of former soldiers who retreated from Russia in 1812.

Rethinking the evolutionary history of human-biting mosquitoes

Evolutionary biologists have long believed that the human-biting mosquito, Culex pipiens form molestus,evolved from the bird-biting form, Culex pipiens form pipiens, in subways and cellars in northern Europe over the past 200 years.

Researchers trace the ancient origins of an urban mosquito species

New research has uncovered the ancient origins of an urban mosquito species, Culex pipiens form molestus, also known as the 'London Underground mosquito' – disproving a long-held theory of when it first evolved.

New gene-editing method can correct many disease-causing mutations in mammalian cells

Some genetic disorders-such as cystic fibrosis, hemophilia and Tay Sachs disease-involve many mutations in a person's genome, often with enough variation that even two individuals who share the same disorder might have a different combination of mutations.

Nuclear binding protein identified as key contributor to trisomy 21-related CHDs

Three copies of chromosome 21 causes Down syndrome (DS), and roughly half of children born each year in the United States with DS-approximately 2,600-also have congenital heart defects (CHDs).

HMGN1 gene linked to heart problems in people with Down syndrome

Nearly half of all babies born with Down syndrome face congenital heart defects, often involving serious malformations that require surgery in the first months of life.

Genetic inflammatory signature defines depression subtypes and treatment response

Researchers led by Prof. Alessandro Serretti at Kore University of Enna have identified a genetic inflammatory signature that defines specific depression subtypes and influences how patients respond to antidepressant medications, according to new peer-reviewed research published today in Genomic Psychiatry.

Molecular evidence connects higher childhood cognitive function to longer lifespan

Researchers led by Dr. W. David Hill at the University of Edinburgh have identified a significant genetic correlation between childhood cognitive function and longevity, providing the first molecular genetic evidence that intelligence measured in youth shares genetic factors with lifespan.

Review reveals how paternal lifestyle shapes sperm epigenetics and offspring health

A new review in Clinical Epigenetics synthesises growing evidence that paternal lifestyle and environmental exposures such as diet, obesity, smoking, endocrine-disrupting chemicals, and stress alter sperm epigenetic marks (DNA methylation, histone retention, and small non-coding RNAs).

New insights reveal persistent genome structure during cell division

Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material.
