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).

Scientists describe dynamic genomic landscape of tumor heterogeneity in hepatocellular carcinoma

Clinician scientists and scientists from the National Cancer Centre Singapore and A*STAR's Genome Institute of Singapore, in collaboration with Singapore General Hospital, the National University Health System, Duke-NUS Medical School, Nanyang Technological University, and collaborators from China, Malaysia, Thailand and the Philippines, have described a dynamic genomic landscape of tumour heterogeneity in hepatocellular carcinoma (HCC).

Evaluating the virucidal activity of blue LED light against SARS-CoV-2 infection

A new study provides some possible explanations to the mechanisms by which antiviral activity is exerted by blue LED light and indicated that the alteration of the SARS-CoV-2 spike protein requires the presence of photosensitizers.

Study reveals the role of intracellular receptor PQBP1 in response to Tau protein

Just as a home security system can alert a homeowner to the presence of an intruder, a protein called polyglutamine binding protein-1 (PQBP1) found in brain cells can alert the body to the presence of "intruding" viruses like human immunodeficiency virus (HIV).

SARS-CoV-2 variants are evolving new ways to evade antibodies and vaccines

Continued replication of severe acute respiratory syndrome-associated coronavirus 2 (SARS-CoV-2) under selective pressure from natural and vaccine-induced immunity has led to the emergence of variants of concern (VOCs) with increased transmissibility or virulence.

Diverse genome sequences generate a polygenic risk score to predict heart disease risk

In a large-scale study of people from diverse ancestries, researchers narrowed down the number of genomic variants that are strongly associated with blood lipid levels and generated a polygenic risk score to predict elevated low-density lipoprotein cholesterol levels, a major risk factor for heart disease.

Keto diet does not appear to work well for women

Scientists from UC Riverside are studying how the popular keto and intermittent fasting diets work on a molecular level, and whether both sexes benefit from them equally.

New research reveals how Europeans evolved greater resistance against anthrax

New research from the Cornell College of Veterinary Medicine has revealed how humans evolved greater resistance against anthrax multiple times during history: when they developed a diet of more ruminants, and when agricultural practices took hold.

Stress accelerates biological clock, but psychological resilience can help manage the effects

Scientists in recent years have developed ways to measure biological age by tracking chemical changes in DNA that occur naturally as people age but occur at different times in different people.

SARS-CoV-2 S2 immunization as a pan-coronavirus vaccine approach

A new mouse model suggests that prior HCoV-OC43 S immunity primes neutralising antibody responses to otherwise subimmunogenic SARS-CoV-2 S exposure as well as promotes S2-targeting antibody responses.
