The Armenians, a population in Western Asia historically native to the Armenian Highlands, were long thought to be descendants of Phrygian settlers from the Balkans. This theory, rooted primarily in the writings of the Greek historian Herodotus, stemmed from his observation that Armenians serving in the Persian army were armed in a manner similar to the Phrygians. Linguists have also bolstered this theory, noting linguistic connections between the Armenian language and the Thraco-Phrygian subgroup of Indo-European languages.

But the first whole-genome study is challenging this long-held belief, revealing no significant genetic link between Armenians and the populations in the Balkan region. The study compares newly generated modern Armenian genomes and published genetic data of ancient individuals from the Armenian highlands with both modern and ancient genomes from the Balkans.

A novel breakthrough, leveraging CRISPR gene-editing technology, is revolutionizing how scientists study sEVs. This innovative approach, known as CIBER (CRISPR-assisted individually barcoded sEV-based release regulator), enables researchers to investigate thousands of genes simultaneously.

By tagging sEVs with unique RNA “barcodes,” CIBER offers unparalleled insights into the molecular processes regulating sEV release, setting the stage for advancements in biotechnology and disease treatment.

Extracellular vesicles, which include sEVs, are small, membrane-enclosed particles released by cells into their surroundings. Their size, origin, and cargo determine their classification. sEVs, typically 30–200 nanometers in diameter, are among the smallest but most intriguing members of this group. These vesicles transport biomolecules—such as RNA, proteins, and lipids —between cells, acting as communication messengers.

Junk DNA may not be so ‘junky’ after all – these regions may hide genetic material coding for tiny proteins involved in disease processes like cancer and immunology.

Our records of the human genome may still be missing tens of thousands of ‘dark’ genes. These hard-to-detect sequences of genetic material can code for tiny proteins, some involved in disease processes like cancer and immunology, a global consortium of researchers has confirmed.

They may explain why past estimates of our genome’s size were way larger than what the Human Genome Project discovered 20 years ago.

The new international study, still awaiting peer review, shows our library of human genes very much continues to be a work in progress, as more subtle genetic features are picked up with advances in technology, and as continued exploration uncovers gaps and errors in the record.
