IRX3 – the main regulator of "obesity genes"?

The IRX3 gene controls body weight and determines the composition of its tissues. This gene is a "switch" that controls the operation of several genetic "programs" in cells at once, scientists from the University of Chicago found out.

DNA sequencing: cheap or accurate?

A promising method of DNA sequencing based on stretching DNA through a nanopore has not fully justified itself. The data obtained with its help still has to be checked by other sequencing machines.

Analysis of encrypted genomes

Microsoft cryptologists have developed an algorithm for encrypting DNA sequences, which allows them to be analyzed by traditional bioinformatic methods and at the same time does not compromise the owner of the genome.

How much Indy does it take to extend life?

The maximum lifespan of drosophila is provided by a moderate amount of the protein of the mutant Indy gene (from the English I'm Not Dead Yet – I'm not dead yet); a little less is its overexpression. Flies with two normal copies of this gene live significantly less.

The secret of the difference in the height of men and women is a gene on the X chromosome

Scientists have found out why, on average, men are taller than women. The key turned out to be in a gene that inhibits the growth of cartilage and is located on the X chromosome.

Cleaning ancient genomes

The creation of a system for separating contamination from DNA will allow geneticists to conduct a more accurate analysis of gene samples of ancient people and animals, which means that it will bring them one step closer to deciphering the secrets embedded in the DNA spiral.

Let's protect coffee plantations from transgenic beetles!

Because of transgenic beetles, coffee becomes more expensive, while they themselves do not starve, eating coffee for about half a billion dollars a year for free. Sometimes leading to ruin, and maybe to suicide of local farmers.

Another genetic company was accused of false statements

The US Federal Trade Commission announced that GeneLink Biosciences, a company specializing in personal genomics, made statements that were not confirmed by scientific data, and also did not provide adequate protection of the genetic information of its customers.

For the particularly gifted, I repeat: men will not die out!

Apparently, the Y chromosome is not destined to disappear: it contains genes that are really necessary for the male body, which have been selected by evolution and which cannot be removed or even edited.

Shut up, Gen, shut up!

By improving the structure consisting of hairpin RNA and microRNA, scientists were able to significantly increase the efficiency and accuracy of RNA interference for gene silencing (suppression of the synthesis of their proteins, from the English silence - to be silent).
