27.03.2017 Scientists have found a mutation that causes infertility in women
The scientists still do not know the cause of 10 to 15% of cases of infertility and 50% of cases of usual (multiple) miscarriage. Researchers from Baylor College of Medicine have revealed a new mutation that reduces women's reproductive success and fertility, Zee News says.
24.03.2017 Scientists have grown a heart tissue on spinach leaves
Modern technologies, including three-dimensional printing, do not allow creating a branched network of blood vessels right up to the capillaries. This is necessary for the oxygen and nutrients delivery providing a tissue growth. A team of researchers from the US is close to solving this problem, Eurek Alert reports.
23.03.2017 The Great Britain considers the theme of "children of three parents" seriously
According to RIA News, it is known that the University of Newcastle became the first institution in the country that received a license for artificial insemination procedures using DNA of three people. The license was issued by the Ministry of Health. The law that permits an artificial insemination using the material of three people came into force in December 2016.
22.03.2017 A unique test for the blood group analysis will save millions of lives
Chinese scientists have developed a new test that shows the blood group in a few seconds. The accuracy of the test is almost 100%, The Daily Mail reports. This is a real breakthrough, because all modern tests require a lot of time and complex equipment. The new method allows to determine the blood group to any person practically.
21.03.2017 Wireless prosthesis solves the problem of vision loss in the most severe cases
According to The Hindu, scientists have developed a high-resolution retinal prosthesis, using nanowires and wireless electronic systems. The prosthesis helps nerve cells in the human retina to respond to light. This technology can help millions of people with neurodegenerative diseases affecting vision.
20.03.2017 Researchers have found the cause of obsessive-compulsive disorder
Obsessive-compulsive disorder (OCD) is characterized by the occurrence of involuntary obsessive thoughts (obsessions) and attempts to get rid of them by means of obsessive actions (compulsions). The scientists of the University of Würzburg have revealed a protein that plays an important role in the development of OCD, UPI.com reports.
17.03.2017 Scientists have found a gene that causes sudden death in young people
According to Zee News, an international team of experts has found that CDH2 gene mutation causes arrhythmogenic right ventricular cardiomyopathy. This rare hereditary heart disease is the main cause of sudden death in seemingly healthy young people.
16.03.2017 The Chinese have conducted a unique experiment on DNA correction
The Medical University of Guangzhou has conducted an unusual experiment. The scientists corrected genetic mutations in the cells of viable human embryos using CRISPR genome correction method. Previously, no one research group carried out such experiment. The main difference of this experiment was the use of normal embryos. Previously, CRISPR was tested only on genetically defective embryos that cannot develop into a fetus. It turned out that the method works much better with normal embryos.
15.03.2017 Apparently, biologists have found the right approach to HIV treatment
For the first time the biologists have managed to induce a powerful immune response to animal version of HIV (monkey immunodeficiency virus) in the body of macaques. Two recently discovered antibodies were helped the scientists in this experiment. These two antibodies affect most strains of HIV. The principle is the same as with immunotherapy for cancer - the body begins to control the disease by itself, RIA News reports.
14.03.2017 Discovery: human bone tissue cells produce a hormone reducing appetite
A team of specialists has found that bone cells produce a hormone called lipocalin 2, which affects the brain areas responsible for a hunger. The levels of this hormone are reduced in people with type 2 diabetes who are overweight and have high blood sugar levels. The study has shown that daily injections of lipocalin 2 help to reduce an appetite and weight, the Daily Mail says.
