A smart tablet controls not only itself, but also the patient

Each Raisin system tablet contains an indigestible sensor, which is a microchip the size of a grain of sand and a thin-film battery that activates upon contact with an aqueous medium after ingestion.

The triumph of computer methods: prediction of the structure of proteins

One of the research teams actively engaged in predicting the structure of proteins using computers is the Washington laboratory of David Baker.

The bioprinter created a functioning piece of heart muscle

According to scientists, the first "marketable" fabrics from the printer will appear on the market in the very next few years.

Recent data about a person

Another 25 genes that affect life expectancy, a neurophysiological mechanism for assessing financial and other risks, a method for assessing the state of mitochondria in vivo and other life sciences news in general and about human life in particular.

It is planned to arrange an "ark in case of an apocalypse" on the Moon

The ark will store DNA, embryos and everything necessary for life and civilization; these resources will be used if the Earth is devastated by a collision with a giant asteroid, a sudden climate change or a nuclear catastrophe.

Credulity and gratitude are hereditary signs

Differences between people in the degree of "trustfulness" and "gratitude" are at least 10-20% genetically predetermined.

New details of blood clotting: a computer model of fibrinogen has been created

Weed out mutants

The organism of a higher animal is able to get rid of mutant mitochondria extremely effectively: they disappear after 2-6 generations. The selection of normal mitochondria occurs in female germ cells or at the subcellular level.

Where can we expect new epidemics?

The authors agree with the position of most epidemiologists that the most important thing is to stop the spread of the disease at an early stage, even when there is no specific method of its treatment.

Creating memories

A new line of genetically modified mice allowed scientists at the Scripps Research Institute to identify cellular contacts formed during the memorization process.

454-sequencing (high-performance DNA pyrosequencing)

A new generation of DNA sequencing technologies, which allows the reading of genetic texts with unprecedented speed and productivity, has found wide application in biomedical research and has become a prerequisite for impressive scientific achievements.

Distributed computing for personalized Medicine

To carry out work within the framework of a joint project on the development of personalized medicine, which received a $2.5 million grant from the National Institutes of Health last October, scientists use tissue microchips, pattern recognition algorithms and network supercomputer computing.

Mouse Alzheimer's under the microscope: day by day

Of course, the neurophysiology of mice differs from that of humans, so it's too early to draw final conclusions. Nevertheless, the work of Professor Hyman and his collaborators strongly supported the hypothesis of the beta-amyloid nature of Alzheimer's disease.

The IntelliDrug tooth dispenses medications in the mouth

The undoubted advantage of the invention is that you do not need to take pills at all. Medications enter the body by themselves, and in most cases a person does not even notice it. According to the creators, the implant does not prevent a person from talking or eating.

Three, six, code

Two nucleotides are connected by a strong covalent bond, and with the third and the amino acid – by weak physico-chemical bonds. To strengthen this connection, we need another three – complementary. It will turn out to be a six, which will be supported by hydrogen bonds between complementary nucleotides.

microRNA – the further into the forest, the more firewood

microRNAs are involved in the processes of individual development of the body, including temporary control, death, proliferation and differentiation of cells, embryonic laying of organs.

World Community Grid: Join the Distributed Computing network!

There are about 650 million personal computers in the world, and most of them use only a small part of their power when working. At the same time, these untapped resources can be used for the benefit of all mankind. To this end, in 2004, the World Community Grid system was created – the largest global computing system for solving the most important humanitarian problems.

Mario Capecci: features of an individual approach

Mario Capecci has had a fantastic academic career. Today, the knockout method, of which Capecci was one of the fathers, is already a classic of molecular biology.

The Science We've Lost

Wages are lower than in science only in such sectors as agriculture, non-productive services for the population, culture and art, education and forestry. Almost every 13th emigrant is a scientist! The main group of emigrants are programmers, biotechnologists, molecular geneticists.

How Molecular Cell Biology is being Killed

In January 2008, the participants of the Molecular and Cellular Biology program found themselves in the information and budget vacuum zone – no one canceled the program, but also did not extend it, as, indeed, other programs of the Presidium of the Russian Academy of Sciences. Those scientists who believed the seriousness of the promises of the Academy of Sciences and returned to Russia, having received grants for 3 and 5 years, found themselves "in limbo."
