Vaccines based on virus–like particles - fast, effective, safe

Safe and effective vaccines, the active component of which are virus-like particles, due to the speed of manufacture, can solve the long-standing problem of the timely appearance of vaccines against rapidly mutating influenza virus.

Nanotechnology: less noise!

The final book of the Nano-Hype study, which was funded by the American National Science Foundation, explicitly states the danger of the formation of a "nanobubble". Of course, many wonderful scientists and entrepreneurs are fruitfully engaged in nanotechnology. But it seems to them that all this hype not only helps, but also hinders.

Genetically modified geniuses

Hobbie-J rats with increased production of NR2B protein in the hippocampus as a result of genetic modification remember new objects three times longer than rats of the original (the smartest among rats) Long Evans line.

Scalpel will be able to "sniff out" tumors

A mass spectrometer connected to an electroscalpel installed in the oncosurgeon's operating room will distinguish malignant tissues from healthy ones based on their molecular characteristics.

Personal genomics: it's time to put things in order

Predicting predisposition to diseases based on individual DNA characteristics will soon become a routine procedure. But the work of companies engaged in the analysis of personal genomes is not standardized enough and needs improvements.

Work is the best geroprotector

People who switch from full-time employment to temporary or part-time work get sick less often and their overall well-being is better than people who immediately stopped working completely. Moreover, pensioners working in their specialty retain their intelligence longer.

Nobel Ribosomes

The achievement awarded with the prize "for research on the structure and work of ribosomes" has played a significant role in the development of science; it also has practical applications — in particular, antibiotics that kill bacteria by turning off their ribosomes.

The gene of the quick mind

The difference in the speed of thinking due to the "correct" allele of the COMT gene is small. But the variants of this gene differ by only one nucleotide, and the molecules of the corresponding protein differ by one amino acid.

Fractal DNA

The DNA in the cell nucleus is packed into an incredibly compact "fractal globule", on the surface of which the genes necessary for protein synthesis move.

Nobel Telomeres

It is a pity that Olovnikov was not among those who received the award. At the same time, Blackburn, Grader and Shostak, who have devoted many years to successful experimental studies of telomeres and telomerase, undoubtedly deserve this award.

The brain-computer interface is squared

The new development is a further step in creating a brain-computer interface. A group of scientists from the University of Southampton has developed a new version of this technology – brain-to-brain communication.

Genome and diseases: counting copies of genes

Predisposition or resistance to diseases is largely due to differences in the number of copies of the corresponding genes. A new study has added a whole dimension to the space of understanding such variations in the human genome.

Cell therapy: a losing streak

The stem cell-based drug closest to entering the market has not passed final trials, and the first clinical trials of therapy using embryonic stem cells have been postponed indefinitely.

Nobel Prize in Chemistry – Biophysics

The Nobel Prize in Chemistry has become a substitute for the non-existent prize in biology, as well as an addition to the inadequately small prize in physics for such an extensive discipline. All the "true chemists" were left behind.

The genetic source of youth

Researchers developing means to prolong youth have two more potential targets – proteins, the inactivation of which prolongs the life of experimental animals and allows them to maintain good physical and mental shape until old age.
