A peptide in an hour
MIT scientists have adapted the synthesis reactions of short (from 30-40 amino acids) proteins in such a way that the entire peptide can be assembled not in a few weeks, but in a little more than an hour.

21.03.2014Intestinal bacteria break down the polyphenols contained in chocolate to smaller and easily absorbed molecules with anti-inflammatory properties, which have a beneficial effect on the heart and blood vessels.
21.03.2014Twenty patients suffering from an aggressive form of brain cancer will soon have another member of the medical team serving them. In this role, the artificial intelligence of the famous Watson supercomputer will act.
21.03.2014American scientists have deciphered how a small fragment of RNA – microRNA-25 – contributes to the progression of heart failure, and have shown that by blocking microRNA-25 antisense RNA, this process can be slowed down.
20.03.2014Tropoelastin-based hydrogel meets all the requirements for use in myocardial regeneration in terms of elasticity and resistance to loads. The "patches" grown on it are able to shrink not only in laboratory conditions, but also in the heart of the experimental animal.
20.03.2014Mutations in the BRCA1 gene lead not only to malignant tumors of the mammary glands and ovaries. If this gene does not work in neural stem cells, the brain they form will be much smaller than it should be.

18.03.2014Today, cancer diagnosis requires analysis of a sample of altered tissue – a biopsy. However, scientists are working on a "liquid biopsy" – analysis of tumor DNA in the blood.
18.03.2014After the introduction of carbon nanotubes into chloroplasts, the ability to photosynthesis increased by 30% in plants, and sensitivity to gases polluting the environment also appeared. The scientists attributed their research to a new field, which they called "plant nanobionics".
18.03.2014The introduction of three transcription factors – proteins regulating the activity of genes – to immune-deficient mice transforms a specific group of cells of the intestinal mucosa into cells close to insulin-producing beta cells.
18.03.2014According to a new evolutionary hypothesis, in the wild, adaptation to a low-calorie diet ensures the preservation of the ability to reproduce in difficult times, and it contributes to an increase in life expectancy only in "greenhouse" conditions.
18.03.2014One of the significant factors determining the reaction of an aging organism to physical activity is the polymorphism of the angiotensin converting enzyme gene.
