Prolonging life: gene therapy instead of starvation?

The prospects are tempting: one injection of a genetically engineered vector with WWP1 will be enough to prolong life by 20%, and at the same time get rid of many age-related diseases. But this is only if scientists manage to achieve the same effect on mammals.

Will an immunosuppressant help you live up to a hundred years?

The aging process can be slowed down, and life expectancy increased, and by taking the drug already in old age. Scientists plan to find out whether it is possible to eliminate the side effect in the form of a decrease in immunity in the course of further experiments.

Pluripotent stem cells: another source

Experts from Germany have managed to turn mature cells taken from the testes of mice into pluripotent stem cells without resorting to artificial introduction of new genes and the use of viruses.

EvoGrid: Modeling evolution

From the first biopolymers to DNA, lipids, cells and multicellular organisms, there is a huge distance. It's hard to imagine that someone is able to go all this way in the laboratory. But you can try to reproduce prebiotic and biological evolution in a computer. This is what the EvoGrid project is doing.

How to grow a new leg? Ask the axolotl!

That there is a tail, like some lizards: the axolotl successfully grows a new fully functional leg, instead of the severed one. Damaged lungs or spinal cord are also reconstructed remarkably. And there are no scars left. That would be so for us.

Nanotransporters will deliver drugs to cancer cells

Many side effects of chemotherapy can be avoided if the drug is delivered purposefully only to cancer cells, to their nucleus. In this case, the effectiveness of the drug increases by several orders of magnitude. This effect can be achieved by using nanotransporters for drug delivery.

Old age is somewhere beyond the horizon

Young people believe that old age comes at 60. Middle-aged people push this bar to 70 years. Those who have reached their 65th birthday believe that old age does not come before 74…

Cancer vaccines: incite the immune system against cancer cells

The idea of an oncovaccine is similar to an antimicrobial vaccine and is based on the fact that there are special carbohydrate molecules on cancer cells. With the help of vaccination, an immune protective reaction is triggered, aimed at cancer cells.

Clone a mammoth? Unreal!

The successes of recent years in deciphering the genetic code of mammoths have given rise to expectations in society of the imminent "return" of these ancient animals. Nikolai Yankovsky says that these expectations have little to do with reality.

I'll sell a kidney. Expensive

The surgeon Dmitry Granov considers stories about abductions of people "for organs" and clandestine clinics to be horror stories, behind which there is nothing but the sick fantasy of their authors. The well-known criminologist Yakov Gilinsky believes that it is impossible to exclude the possibility of committing such crimes in Russia. The demand for donor organs is huge, and the prices are too high for criminal structures to bypass this topic.

The interchangeability of regulatory genes protects against diseases

There are much more similarities between genes and computer networks than previously thought. In both cases, the key elements of the systems are duplicated. This discovery will allow us to find vulnerable genes responsible for the development of diseases.

Biopharmaceuticals: originals and analogues

Analogues of biopharmaceutical drugs are called biosimilars or bioengineers, in the USA they are called modified biopharmaceuticals. Reproduced biopharmaceuticals are also called "biosimilars" ("biosimilars"), and this term has been used most frequently in recent years.
