Vegetarians can be safely considered not only fanatics, but also lost sheep. Almost no one argues with them. It's a difficult business, I'll tell you. Isn't that why the vegetarian movement has turned around so famously, recruiting more and more recruits into its ranks?

IBM develops DNA-based chips

The search for ways to reduce the size of chips and increase the number of transistors placed on them led IBM scientists to a completely new way of creating processors using DNA molecules.

Where can we expect new epidemics?

The authors agree with the position of most epidemiologists that the most important thing is to stop the spread of the disease at an early stage, even when there is no specific method of its treatment.

Creating memories

A new line of genetically modified mice allowed scientists at the Scripps Research Institute to identify cellular contacts formed during the memorization process.

Human population genetics: the first of a new wave of research

New techniques that provide simultaneous analysis of hundreds of thousands of genetic markers provide results sufficient to draw conclusions about interactions between human populations and prehistoric human migrations with a much higher degree of reliability than was previously possible.

Eva's Daughters: genes, history and geography

"Y-chromosomal Adam" and "mitochondrial Eve" are not real people, but virtual points from which the branching of the molecular family tree of mankind begins.

Sons of Adam: Genes, history and geography

Now any of us can determine our ancestry to the progenitors of mankind. However, not biblical, but molecular-genetic – "mitochondrial Eve" and "Y-chromosomal Adam".

Where are the most mutants?

Several research groups are trying to determine which of the human races' genomes contain more mutations and how dangerous these mutations are for its representatives.

Hot spots of modern gerontology

The increase in life expectancy and the aging of the population of developed countries have increased interest in gerontology, and above all, in the study of the primary mechanisms of aging of organisms and populations, as well as factors determining life expectancy.

454-sequencing (high-performance DNA pyrosequencing)

A new generation of DNA sequencing technologies, which allows the reading of genetic texts with unprecedented speed and productivity, has found wide application in biomedical research and has become a prerequisite for impressive scientific achievements.
