Gene

A gene is a unit of heredity in a living organism. It normally resides on a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism. All living things depend on genes, as they specify all proteins and functional RNA chains.

What are Genes?

Deoxyribonucleic acid (DNA) is the chemical information database that carries the complete set of instructions for the cell as to the nature of the proteins produced by it, its life span, maturity, function and death. Genes are the working subunits of DNA. Each gene contains a particular set of instructions, usually coding for a particular protein or for a particular function.

Heavily processed foods may raise heart disease risk beyond poor nutrition alone

A 2026 review in Cardiology in Review reports that higher intake of ultra-processed foods is consistently associated with greater risks of cardiovascular disease, stroke, and cardiovascular mortality across cohort studies and meta-analyses. The paper also highlights plausible mechanisms involving gut dysbiosis, oxidative stress, and NF-κB-driven inflammation, with additives such as emulsifiers, preservatives, dyes, and sweeteners discussed as potential contributors.

The new microchip electrophoresis system MultiNA II MCE-301- High sensitivity detection, improved analysis function and operability

Shimadzu has recently released the MultiNA II MCE-301 microchip electrophoresis system. By automating the entire process of electrophoresis, which takes more than two hours by hand (creation of gels, dispensing reagents, dispensing sample, separation, dyeing, cleaning of equipment), the company significantly improves the efficiency of genetic analysis operations.

New brain atlas reveals how the human neocortex forms over time

In a bid to better understand, and potentially treat, a host of conditions that affect early cognition, neurodevelopment and the brain later in life, investigators at Johns Hopkins Medicine and colleagues throughout the world have been mapping the molecular construction of the human brain.

CDC tracks SARS-CoV-2 BA.3.2 global rise and finds early signals in U.S. wastewater

CDC surveillance shows that the highly divergent SARS-CoV-2 variant BA.3.2 spread to at least 23 countries and was detected in U.S. travelers, patients, airplane wastewater, and wastewater samples across multiple states. The report highlights wastewater and traveler-based genomic surveillance as early warning tools while noting that BA.3.2 has immune-evasion potential but has not rapidly displaced other circulating lineages.
