In search of an ancestor

What information about the origin of a person can be extracted from the genome if modern methods of its analysis are used?

DNA is alive and glowing

Chemists from Switzerland have developed a revolutionary dye that allows you to "highlight" DNA molecules in living cells without disturbing their vital functions, which will allow scientists to uncover many secrets of life.

The age of menopause is determined by genes that protect the DNA of eggs

British geneticists have discovered four dozen DNA sites, on the work of which the time of menopause in women depends, and found out that taking care of their condition can help ladies maximize their sex life.

Geroprotectors: the most complete database (2)

Motivation to create a database Geroprotectors.org there was a desire to provide researchers interested in aging-slowing compounds with a universal resource that allows them to save a huge amount of time searching for data, studying literature and expert analysis.

Geroprotectors is an easy-to-use public database containing information on more than 250 experiments in which more than 200 confirmed or potential geroprotectors were studied.

Cell sorter the size of a mobile phone

Based on acoustic waves, the sorter, which is a small and inexpensive device of the "laboratory on a chip" type, is able to compete with traditional devices using fluorescent labels.

Hydrogel will help in the treatment of heart attack

A sticky, protein-rich hydrogel developed by Johns Hopkins University researchers delays stem cells in the infarction zone and supports their vital activity, providing more effective damage recovery.

New scissors for genetic engineering

Cpf1 works like CRISPR-Cas9, which is currently used in experiments to change the human genome, but it has a number of advantages.

Mutating humanity

In the 15 years that have passed since the first rough reading of the human genome, our knowledge of mutations that occur in our genes has increased many times, and the methods of studying them have become much more effective and diverse.

When viruses were big…

American biologists have shown that viruses are not lifeless random fragments of DNA that have become "alive" by chance, but the product of the evolution of ancient cell-like structures that have adapted to intracellular parasitism.

How have the principles of bioethics changed modern clinics?

Philosopher Elena Bryzgalina – about the relationship between doctors and patients, ethical problems of biomedicine and the relationship between law and morality.

Telepathy via computer

American scientists were able to make two people read each other's thoughts at a distance. The participants of the experiment successfully played a question-and-answer game: one of them asked a series of questions, and then guessed exactly which object the second one was thinking about

Paralyzed patient learned to walk without an exoskeleton

The man, whose both legs were completely paralyzed, learned to walk on his own again. According to the authors of the study, this is the first time in history when a patient regained the ability to move without using robotic exoskeletons.

An emotion enhancer gene

Owners of one of the SERT gene varieties are more prone to depression if life cracks, but they are happier if everything goes well.

STAP cells are the result of an error, not a falsification

Such errors often occur in biological laboratories, but they must be taken into account in order to obtain pure scientific data.
