Electrical impulses from the sensor in the bionic finger are transmitted to the microneedle connected to the median nerve, and then to the brain.
14.03.2016Electrical impulses from the sensor in the bionic finger are transmitted to the microneedle connected to the median nerve, and then to the brain.
14.03.2016The loss of stop codons on mRNA leads to the formation of long lysine chains at the end of synthesized proteins. When the protein quality control mechanism is violated, defective proteins accumulate and form toxic aggregates.
11.03.2016An interesting discovery for both fundamental and applied science: some of the bacterial CRISPR systems are able to remember information not only from DNA, but also from the RNA of viruses.
10.03.2016For a long time it was believed that endogenous retroviruses do not perform any functions. But a new study shows that our body has turned some of them into weapons against modern viruses.
10.03.2016American researchers have found out how obesity caused by excessive consumption of fatty foods contributes to the development of colon cancer.
09.03.2016German scientists have found out the molecular mechanism of self-renewal of stem cells, which allows them to either maintain pluripotency or differentiate into cells of a certain tissue.
09.03.2016Russian scientists have developed a system that allows detecting malignant tumors by screening and measuring the clinical parameters of skin neoplasms with sufficiently high accuracy.
04.03.2016The aging clock starts ticking even before we are born, but its course can be slowed down by providing the developing embryo with sufficient oxygen supply.
04.03.2016Biologists from Duke University have developed a strain of E. coli that can exist under certain conditions only in the form of a dense colony – any bacterium that splits off from the rest almost immediately dies.
04.03.2016Giant viruses have their own parasites, virophages, which themselves contain parasitic genetic elements called transpovirons, bringing the nesting of parasitism to three levels.
03.03.2016The molecular basis of intellectual and neurological disorders characteristic of Down syndrome is a decrease in the myelination of nerve fibers.
03.03.2016A mobile device connected to a smartphone for molecular express diagnostics of infectious diseases does not need special sample preparation, an energy source and qualified personnel.
03.03.2016Scientists have linked the molecular pathway associated with Parkinson's disease with genes mutating in amyotrophic lateral sclerosis (ALS).
02.03.2016In this article, the author collected questions about bioinformatics, which he himself asked three years ago, when he was still a student of the Faculty of Mathematics, and tried to answer them.
02.03.2016If clusters of pathologically folded proteins in the nuclei of neurons practically do not affect their functions, then protein aggregates located in the cytoplasm disrupt important transport routes between the cytoplasm and the nucleus.
29.02.2016The very first experiences of alcohol consumption change the brain forever, determining many habits and addictions of the future.
26.02.2016The development and improvement of technologies for human immersion in suspended animation promise to bring fairy-tale stories to life.
24.02.2016The breakdown of ontogenesis into a sequence of episodes of full life and suspended animation is so far the only theoretically possible way to artificially "stretch" life expectancy and slow down aging.
24.02.2016"Stentrode", a new type of electrode, which is similar in design to a medical stent, can provide high-quality recording of neuronal signals without the need for dangerous surgical operations on the open brain.
18.02.2016A new method of atomic force microscopy makes it possible to trace the movement of DNA both outside and inside DNA-protein complexes and to examine telomeres at the ends of chromosomes in detail.
