Genetics

Genetics is the study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.

How Do Genetic Mutations Cause Disease?

Mutations in genes can lead to genetic disorders, impacting health. Understand the types, causes, and implications of genetic mutations and disease.

Hidden protein linked to severe COVID-19 and lung disease risk

A genetic difference carried by nearly one in three people may increase the risk of severe COVID-19 and lung fibrosis by disrupting the function of a previously unknown protein, according to a new study.

AI image-based risk scores enable dynamic breast cancer assessment

Using artificial intelligence (AI), researchers found that image-based risk scores for breast cancer derived from screening mammograms evolve over time and differ between women who develop cancer and those who do not, opening the door to a new era of dynamic breast cancer risk assessment.

Parental genes rather than pregnancy weight influence childhood body mass index

The link between parents' body mass index (BMI) and their children's BMI in childhood is driven largely by genetic inheritance, rather than by any direct biological effects of parental weight during pregnancy, a new study suggests.

MSU researchers develop tool to observe complex molecular choreography in real time

A lot of things need to go right on a molecular level for immune cells to launch an adaptive response to an infection.

Longer breastfeeding links to fewer ADHD symptoms in children

Longer durations of full breastfeeding are linked to fewer ADHD symptoms in children, suggesting early feeding patterns may influence neurodevelopment.

Using the mathematics of quantum mechanics to improve neuroblastoma outcomes

For a child diagnosed with neuroblastoma-the most common infant cancer, occurring when early nerve cells grow out of control-the path to treatment isn't simple.

UCLA researcher receives grant for advanced osteosarcoma immunotherapy

Physician-scientist Theodore Scott Nowicki, MD, PhD, an assistant professor in the department of pediatrics hematology/oncology and microbiology, immunology, & molecular genetics at the David Geffen School of Medicine at UCLA, has been awarded the Hero Grant from MIB Agents, a nonprofit organization dedicated to improving outcomes for children and young adults with osteosarcoma.

Study links genes and sleep habits to Alzheimer's risk

New research from Edith Cowan University (ECU) has discovered an important link between our genes and sleep habits, suggesting they work together to influence early brain and cognitive changes associated with Alzheimer's Disease, long before symptoms appear.

Mount Sinai study connects social determinants of health to disease risks

A new study from the Icahn School of Medicine at Mount Sinai shows that social determinants of health-including environmental conditions, health behaviors, access to resources, and social well-being-can play an equally important or even greater role than genetics in predicting a person's risk of developing common diseases.

Novel gene network approach reveals new schizophrenia risk genes

Scientists have long known that schizophrenia runs in families, but pinpointing exactly which genes contribute to risk has been like searching for needles in a haystack.

Synthetic gut communities reveal how diet rewires the microbiome

Synthetic microbial communities give researchers controlled models for testing how diet reshapes gut microbial ecology, metabolism, and host-relevant responses. The review highlights how SynComs can strengthen causal inference, improve intervention testing, and support future precision nutrition, while noting major challenges in stability, standardization, and ecological realism.

Study discovers epigenetic mechanism protecting tooth progenitor cells from stress

An epigenetic "mechanostat" has been discovered that protects tooth-forming progenitor cells from mechanical stress and supports lifelong tissue renewal.

Obesity genes have stronger impact on modern generations

People who carry genetic variations linked to obesity are more likely to be heavier now than individuals with the same variants who were born before the recent obesity epidemic.

Gut microbes may help explain why obesity and type 2 diabetes become harder to reverse

This review describes how gut microbial messengers, including SCFAs, microbiota-modified bile acids, neuroactive metabolites, and extracellular vesicles, may shape obesity and type 2 diabetes through the microbiota-gut-brain axis.

Onion-loving gene linked to lower diabetes and blood pressure risk

Imagine if a doctor could look at your DNA and predict not just your disease risk, but also which foods you're drawn to – and whether those cravings are quietly protecting you.

Autism study reveals shared brain cell changes during early development

Hundreds of genes have been linked to autism, yet the precise molecular and cellular mechanisms behind it remain largely unclear.

Houston Methodist study reveals how strep bacterium causes infection

A fast-rising strep bacterium has become increasingly notorious for causing serious infections in humans, including complications that can lead to muscle damage and patient death. New Houston Methodist research appearing in The American Journal of Pathology, published by Elsevier, sheds light on how Streptococcus dysgalactiae subspecies equisimilis (SDSE) causes disease and may provide important insights to aid in vaccine development.

Semaglutide, omega-3s and diet shift epigenetic aging clocks in human studies

A systematic review identified 41 human studies evaluating interventions targeting next-generation DNA methylation-based aging clocks. Pharmaceutical, lifestyle, supplement, clinical, and psychosocial interventions shifted some clock outputs, but these biomarkers remain investigational rather than proven clinical surrogates.

Hormone cycles dictate how the brain absorbs neuroprotective drugs

Consider what we ask of a clinical trial. We gather people who differ in nearly every way that matters, we give them the same drug at the same dose, and then we average the result and call the average truth.
