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.

Study reveals tumor defense mechanisms in colorectal cancer

Colorectal cancer is one of the leading causes of cancer death worldwide. In recent years, immunotherapies-treatments that reactivate the immune system to attack tumor cells-have transformed the treatment of many types of cancer.

Researchers refine tools to map DNA’s 3D structure inside cells

DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated-able to read not only the code itself, but how it's arranged in space.

Alzheimer’s breakthrough reveals how tweaking one gene shields brain connections

Lowering the transcription factor PU.1 reprograms microglia into a neuroprotective, lymphoid-like state that compacts amyloid, blocks tau spread, and preserves synapses in Alzheimer’s disease. Microglial CD28 signaling helps restrain inflammation, revealing a regulatory switch that may inform future immunotherapies targeting microglia rather than neurons.

Two main methods for discovering disease genes reveal distinct aspects of biology

The two main approaches for discovering disease genes reveal distinct aspects of biology, a new study shows. While both methods are widely used, the research found that they identify different genes, with major implications for drug development.

Oxidative stress linked to repetitive behaviors in mice

Abnormal repetitive behaviors in mice are strongly linked to multiple biomarkers of oxidative stress, which occurs when antioxidants cannot counteract the effects of harmful molecules in the body, according to a study published November 5, 2025, in the open-access journal PLOS One by Kendall Coden and Dr. Joseph Garner of Stanford University, U.S.

Newly identified microglia subtype offers protection against Alzheimer’s disease

In Alzheimer's disease, the leading cause of dementia, microglia-the brain's immune defenders-can act as both protectors and aggressors, shaping how the disease progresses.

Bowel cancer’s “Big Bang” moment reveals how the disease takes shape

Like the astronomical explosion that kickstarted the universe, bowel cancer has a "Big Bang" moment which determines how it will grow, according to new research from Cancer Research UK and Wellcome Trust-funded scientists.

Do gut microbes cause autism? New research says diet plays the bigger role

In a family-based study, researchers found that children with autism spectrum disorder (ASD) shared similar gut microbiomes with their relatives but showed distinctly different eating habits. Their preference for sweets and limited vegetable intake suggests behavior-driven dietary choices may influence, rather than result from, microbiome differences.

USC researchers map genetic architecture of the human corpus callosum

For the first time, a research team led by the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC has mapped the genetic architecture of a crucial part of the human brain known as the corpus callosum-the thick band of nerve fibers that connects the brain's left and right hemispheres.

Over one-third of men would rather endure stressful situations than discuss prostate health

A new survey from Orlando Health reveals that over one-third of men (38%) would rather endure stressful situations, such as watching their team lose a big game or being stuck in traffic, than discuss their prostate health.

Stress hormones may silence crucial neuronal genes through specific RNA molecules

What if the brain's response to stress could be read not in fleeting neurotransmitter bursts, but in the quieting of genes deep inside chromatin? Researchers at the University of Alabama at Birmingham have now shown that stress hormones may silence crucial neuronal genes through an unexpected class of RNA molecules that operate not by encoding proteins, but by reshaping the genome's architecture.

Combined analysis of three blood tests enhances heart attack risk prediction

A combined analysis of blood tests to measure three biomarkers linked to higher risk of cardiovascular disease-lipoprotein a (Lp(a)), remnant cholesterol and high-sensitivity C-reactive protein (hsCRP)-may help identify high-risk individuals earlier and guide more personalized prevention strategies, according to a preliminary study to be presented at the American Heart Association's Scientific Sessions 2025.
