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).

Vascular anatomy influences experimental stroke treatment effectiveness

A preclinical study from Duke University researchers suggests that the effectiveness of an experimental approach to limiting stroke-related brain injury may depend not only on the drug itself, but also on the brain's collateral circulation: the network of small "backup" blood vessels that can help sustain tissue when a major artery is blocked.

Three-dimensional genome structure shapes complex traits in cephalopods

Octopuses, squid and cuttlefish, collectively known as coleoid cephalopods, have evolved exceptionally large and elaborately structured nervous systems capable of complex behaviours such as problem-solving and rapid camouflage.

Study reveals how different plant saponins alleviate ischemic stroke

Ischemic stroke accounts for approximately 85% of all strokes and remains a major cause of death and long-term disability.

Severe long Covid associated with distinct oral and lung microbiomes

A study of more than 700 people has shown that those with long Covid have distinct differences in the mix of bacteria that live in their mouths and lungs, according to a study published today (Monday) in the European Respiratory Journal.

Tiny archaeon offers new clues to the minimum genetic requirements for life

Scientists have discovered a previously unknown microorganism, which has the smallest genome ever found, that is possibly able to replicate and express its own genetic information.

Polymeric nanomedicine strategies improve solid tumor immunotherapy outcomes

Solid tumors are not merely collections of malignant cells but complex ecosystems comprising tumor cells, stromal cells, and the extracellular matrix (ECM).

FDA approves atezolizumab combination for stage III colon cancer with deficient DNA mismatch repair

The Alliance for Clinical Trials in Oncology (Alliance) today announced that the U.S. Food and Drug Administration has approved the immunotherapy drug atezolizumab (Tecentriq) in combination with fluoropyrimidine and oxaliplatin chemotherapy, for the adjuvant treatment of patients with stage III colon cancer with deficient deoxyribonucleic acid (DNA) mismatch repair (dMMR).

Bonn researchers successfully rejuvenate human cells in a test tube

Researchers from the University Hospital of Bonn and the University of Bonn have succeeded in dramatically rejuvenating human cells in a test tube.

Gut bacteria may help explain why endometriosis pain varies

A study of 50 women with surgically confirmed endometriosis found that differences in gut bacterial composition were associated with menstrual pain, urinary symptoms, and infertility.

DNA Typewriter tracks cell divisions and developmental decisions in mice

Scientists have succeeded in reconstructing the family tree of cells in a developing mouse embryo. They recorded cells' relationships, starting when the fertilized egg first split in two and ending after the body with organs took shape.

Nicotinamide riboside fails to slow progression of early Parkinson’s disease

A major clinical trial involving 410 people with early Parkinson's disease has found no clinical benefit from nicotinamide riboside (NR), a compound that increases cellular levels of nicotinamide adenine dinucleotide (NAD). The findings are published in JAMA.

Study explains how sickle cell variant shapes malaria parasite infections

Malaria is one of the deadliest infectious diseases on the planet, afflicting people for the entirety of recorded history.

Universal germline genetic testing catches missed cancer risks in older patients

Universal germline genetic testing of nearly 40,000 patients with solid tumors detected a substantial proportion of inherited gene variants that would have been missed by the standard germline testing approach that excludes those over age 50.

Study links non-brain gene variant to anorexia risk

A gene primarily active in fat and muscles could make a person more susceptible to anorexia nervosa, a deadly eating disorder with one of the highest mortality rates of any psychiatric disease.

Study finds age and body composition may explain gut bacteria differences between milk drinkers

A study of 265 adults suggests that gut bacteria differences between cow's milk and plant-based drink consumers may reflect individual characteristics rather than milk choice.

Ancient gut microbes migrated with humans across the globe

As waves of humans left Africa tens of thousands of years ago, eventually populating the entire planet, they were joined on their world-conquering ride by the trillions of microorganisms that compose the gut microbiome.

Study reveals link between mtDNA copy number and cancer severity

Mitochondria are small organelles within cells that play a central role in vital cellular processes, especially energy production.

Could speech offer a window into aging?

Research on speech clocks shows promise for aging biomarkers, connecting speech age gaps to dementia phenotypes and social factors in a large cohort study.

UCLA scientist develops new way to map cellular metabolism

Nutrition advice is everywhere. Eat more protein. Cut back on sugar. Get more fiber. But beneath all that advice is a surprisingly basic gap in our understanding: Scientists still have a limited view of what happens when specific nutrients reach individual cells inside the body.
