American scientists from Columbia University have found that the hormone osteocalcin can be a “cure” for the brain aging. The researchers noted that osteocalcin is produced by bone tissue cells and even small physical activity contributes to its activation.

Scientists of American University of Colombia have created a unique test that detects the presence of 307 bacterial pathogens by saliva or blood test.

Hydroquinone, which is contained in chocolate, tea, coffee and wine, in combination with zinc slows down the aging process in the human body and prevents oxidative stress.

In the future, everyone will have a chip with stem cells inside. This chip may actually replace the medical card. It is going to be used to perform laboratory tests and to create a truly personalized medicine (each drug can be tested on such chip without endangering the person). From the biological point of view, the system is as complex as possible. Plus, it has the genetic imprint of the cells owner.This means that tests will be as accurate as possible.

American researchers have found that patients with type 2 diabetes are 2.3 times increased likelihood of developing pancreatic cancer. Experts have analyzed data about 50 000 people hospitalized between 1993 and 2013, The Deccan Chronicle reports.

As "Remedium" notes, Russian researchers are working to create the first domestic recombinant vaccine against cholera. Unlike the already existing medicinal products, the Russian vaccine promises to be safer than analogs. The vaccine against cholera is a project of the State Research Institute of Highly Pure Biopreparations of FMBA of Russia.

A new painkiller can be as effective as opioid analgesics. An important advantage of the compound synthesized by scientists is that there is no addictive effect. Researchers have already tested anesthetizing in mice, UPI.com reports.

In 1953, scientists Rosalind Franklin, James Watson and Francis Crick were able to study the structure of the double helix of DNA molecule. This discovery has made a fundamental contribution to the development of molecular biology. Recently, Australian scientists have found out that the double helix is not the one possible form of DNA, Komsomolskaya Pravda reports.

Almost every cell of the human body has its copy of the genetic material enclosed in the chromosomes. In the process of cell division, the end parts of chromosomes can be lost. To prevent this they are protected by special elements of DNA - telomeres. The formation of telomeres is regulated by the enzyme telomerase, "Vlad Time" reports.

The treatment of fractures can last up to 12 weeks. If the lower extremities are damaged, the person has to stay in a lying position for a long time or use crutches. As The Daily Mail notes Swedish scientists have designed a unique glue that can fix a fracture just in 5 minutes.
