Tracer nanoparticles

Harmless calcium phosphate particles with a size of 20-50 nanometers successfully pass into cells and dissolve, releasing their "cargo" – a drug and a fluorescent dye.

Cocktail for little roommates

Developed more than thirty years ago, a special solution for the recovery of patients after surgery later found registration in toxicology, and in the light of new knowledge about the symbiosis of humans and bacteria proved to be in demand in the treatment of a number of diseases.

Old people! Don't be afraid of sex!

Now a person aged 65 can safely expect to live another two decades or so. Naturally, many people want to make up for those hours of sex that were "lost" earlier due to stressful work, crying children or fears of getting pregnant.

Insidious test tubes

Perhaps many of the problems faced by geneticists and microbiologists when growing cell cultures in the laboratory are due precisely to the influence of the test tube material, due to which some indicators may differ from the correct ones by dozens of times!

On the gene grounds

Medical genetics is developing so rapidly that applied medicine simply cannot keep up with it: treating doctors and geneticists almost do not cooperate, and it is generally unclear whether society is ready for such revelations.

A word about the genetics of behavior

It is clear that practically nothing is yet clear in the genetics of behavior. However, it is also clear that psychologists will soon have to arm themselves with modern tools for analyzing the genetic characteristics of the participants in their research, in addition to outdated Eysenck tests and other questionnaires.

Genes and behavior: humans are just like butterflies and birds

To solve the world's problems, we use old, proven genetic and neural circuits that have evolved over the course of evolution to regulate our relationships with fellow tribesmen in small collectives. And if so, then it's time for political scientists to join forces with specialists in behavior genetics, neuroscientists and evolutionary psychologists.

Telomeres and HIV infection

Telomerase genes also work in killer lymphocytes, which are also required to multiply rapidly in order to perform their tasks. However, the hunt for hidden immunodeficiency viruses turns out to be so long that these genes gradually stop turning on. Perhaps TAT2 or other, more powerful telomerase activators will solve the problem

Adenoviruses reprogram somatic cells into pluripotent ones

Adenovirus reprogramming of cells is much less effective than using retroviruses. But at the same time, no tumor formations appeared in any case, and the genomes of the resulting pluripotent cells do not have viral inserts.

Exoskeleton for hard workers and old people

The main goal of the creators of the Walking assist portable exoskeleton is to give the joy of movement to old people who are still able to walk, but already with difficulty. And the second purpose of cyberstans is to equip workers on the conveyor.

Lifestyle Genetics

According to the latest research, our genes are not static. The human genome is an open system that reacts sensitively to the peculiarities of diet, lifestyle, as well as to external factors, such as the state of the environment.

"Pills for old age" are getting closer to clinical research

SRT1720 activates the same receptors in cells as the repeatedly studied compound resveratrol, which, as experiments have shown, prolongs the life of obese mice (and not only them) and makes rodents more resilient.

Mutant killers take orders

A little blood is taken from the patient's vein, all T-killers are isolated from this blood, then a gene encoding a mutant receptor protein is inserted into their DNA in an active form, cells are multiplied in culture and injected back into the patient. According to some indicators, the winning mutant surpassed its progenitor by more than 100 times.

The color genome is cheap and fast

The complete genomes of two more people have been deciphered: a Nigerian and a Chinese. A detailed analysis of the first "color" genomes is still ahead, but the speed and cheapness of decoding already promise the imminent advent of the era of personal genomics. What this era will look like is unclear.

Personal Genome Project: The End of Privacy

The participants of the Personal Genome Project were not afraid to disclose the most personal information about themselves. They did this quite deliberately, making a choice between preserving privacy, privacy and supporting science and, possibly, their health.

Autoantibodies will help predict brain diseases

With the help of molecular blood testing, stroke can be predicted and prevented. Scientists used for this purpose the "scavengers" of the human body – autoantibodies that help get rid of proteins that have worked out their own.
