The program "Molecular cell biology" extended life for another year

Humanity has come to a turning point in its history. It will either find a way to survive in a world that will be changed by global warming and the robotoom, or it will plunge into the era of obscurantism, says English futurist James Martin.

The harmfulness of ultraviolet depends on the structure of DNA at the time of irradiation

One of the most sensational scientific achievements of the outgoing year was the development of methods for genetic reprogramming of human somatic cells, converting them into full-fledged analogues of embryonic stem cells. They are commonly referred to as induced pluripotent stem cells (iPSC) – induced pluripotent stem cells (iPSC).

Neurons commit suicide because of loneliness

If a nerve cell does not receive enough stimuli from the surrounding cells, it starts the process of self-destruction (apoptosis). The mechanism of self-destruction plays an important role in stroke, Alzheimer's disease and motor neuron diseases, leading to the loss of nerve cells necessary for the full functioning of the adult brain.

Early diagnosis of cancer by urine analysis

These cells were found for the first time in the tissue of a recently transplanted and, accordingly, actively regenerating donor liver. For 30-50 thousand hepatocytes, there are only 2-4 cells in it, expressing in large numbers all known stem cell marker proteins, such as Stat3, Oct4, Nanog, ELF and the TGF-beta receptor.
