Genetics

Hidden threat

In the genome of each person there is at least one dangerous (usually recessive, not harmful to its carrier) mutation. But inheritance by offspring of two alleles of a defective gene leads to the development of serious diseases and even intrauterine death.

Genetic modernization

There are no significant differences between the mechanisms of genetic modernization and the natural processes of genetic modification, so it is quite reasonable to assume that the production of GM foods does not carry additional risks.

Go further away

A small exoskeleton is worn on the legs and does not require power sources. The device saves up to 7% of the energy that the body spends when walking. The device weighs 300-500 g, so the advantage in energy is not canceled by carrying heavy loads.

Morbidity statistics by search queries

The analysis of queries entered by users into search engines will allow predicting the spread of non-communicable diseases, such as cancer, stroke and cardiovascular diseases.

Prosthesis with wireless control

American biotechnologists have created a unique prosthetic arm that connects to the brain through a simple "cap" for EEG and does not require implantation of electrodes into the cerebral cortex or other invasive medical procedures.

Genetics suggests, and epigenetics disposes

Epigenetics has become the link between the outside world and genes that scientists have been looking for for so long. She finally put all the dots over the "I" in more than a century of discussion about sociogenetism and biogenetism.

What do magnetic waves look like?

A solid-state compass chip that transmits signals to the cortex of a blind rat responsible for processing visual information allowed the animal to "see" geomagnetic fields.

The complete Encyclopedia of oncogenes

A detailed catalog of cancer genes will allow selecting the optimal therapy for each patient, selecting targets for the development of anti-cancer drugs, creating experimental models of animals and cell lines for cancer research, testing new drugs and treatment methods.

Non-oncogenic embryonic stem cells

Embryonic stem cells treated with a drug for the treatment of oncological diseases, after differentiation into dopaminergic neurons and transplantation into the brain of mice, unlike "untreated", do not turn into cancerous.

Dendritic cells against melanoma

The development of a prototype cancer vaccine from mutated tumor proteins has become a small breakthrough in personalized medicine, on which most hopes are pinned in the fight against cancer.

Not from cancer, but from Alzheimer's

The substance AZD0530 as a cure for cancer has not shown encouraging results, and would have been forgotten if not for a new project of the National Institutes of Health, which launched a project giving a second chance to non-working drugs.

Immortality and extended youth

It seems that prolonged youth is no longer a fantasy, and very soon we will be able to maintain beauty and health throughout our lives. But immortality still seems like an impossible mission.

A "family tree" has been compiled for prostate cancer

Peculiar genealogical trees compiled by scientists show that most of the oncogenic mutations are common to all secondary tumors in each patient. These shared genetic roots could potentially be the Achilles heel of metastases.

Editing DNA will help the staphylococcus gene

American scientists have managed to slightly improve the method of genome editing – the CRISPR/Cas9 system. They found a variant of the Cas9 protein that is easier to deliver to cells than previously used variants.
