DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

AI helps neurosurgeons identify brain tumor types on the spot

What type of brain tumor does this patient have? AI technology helps to determine this as early as during surgery, within 1.5 hours. This process normally takes a week.

Fragile X syndrome may be unfolding in brain cells even before birth

Fragile X syndrome, the most common form of inherited intellectual disability, may be unfolding in brain cells even before birth, despite typically going undiagnosed until age 3 or later.

New blood test could detect ovarian cancer early, improve treatment

High-grade serous ovarian carcinoma (HGSOC) is the most common type of ovarian cancer. It is also the most lethal form, in part because clinicians do not have effective ways to screen women for it during the cancer's early stages, when it's easiest to treat.

Study supports genetic predisposition to chronic regional pain syndrome in a third of cases

Genes may be responsible for third of complex regional pain syndrome cases. But the condition is less common in men, even though they are more likely to have the 4 genetic variations implicated in heightened risk, suggesting that there may be sex specific causes, say the researchers.

Is your DNA steering you towards a vegetarian diet?

Researchers using the UK Biobank identified genetic markers linked to strict vegetarianism, revealing potential connections between vegetarianism, lipid metabolism, and brain activity. The study highlighted genes, particularly those active in the brain and related to cholesterol movement, as influential in an individual's inclination towards a vegetarian lifestyle.

Breast milk microbiome changes after COVID-19 vaccination, linked to enhanced infant protection

Study explored the association between BNT162b2 vaccine-induced antibodies and the breast milk microbiome in 49 breastfeeding mothers, revealing that post-vaccination alterations in the microbiome were linked to humoral protection against SARS-CoV-2.

Midbody remnant found to play role in cancer spread

Once thought to be the trash can of the cell, a little bubble of cellular stuff called the midbody remnant is actually packing working genetic material with the power to change the fate of other cells - including turning them into cancer.

Harvard neuroscientist seeks to capture synapse-level connectome data from a mouse brain

The human brain is a tangled highway of wires emanating from nearly 100 billion neurons, all of which communicate across trillions of junctions called synapses. "Depressingly complex," Harvard neuroscientist Jeff Lichtman calls it.

New discovery sheds light on how BRCA1 mutations cause cancer in women

Three decades after discoveries linking mutations in the BRCA1 gene to breast and ovarian cancer susceptibility, research led by Mays Cancer Center at The University of Texas Health Science Center at San Antonio (UT Health San Antonio) has pinpointed the molecular mechanism by which a large portion of these mutations cause cancers in women.

Does smoking tobacco damage sperm quality?

Tobacco smoking is linked to diminished semen quality by triggering stress reactions in sperm cells, a study in the journal Antioxidants reveals. Researchers identified that smokers had poorer sperm quality, possibly due to elevated stress responses in their sperm cells.
