I eat what I want and lose weight

Knockout of the IKKE gene in mice not only prevents excess weight gain, even on a very fatty diet, but also protects them from obesity-related symptoms leading to the development of type 2 diabetes.

"Sticky ends" of DNA for assembling micro- and nanostructures

Specialists from New York University managed to solve the problem of controlled unification of micro- and nanoparticles, on the surface of which DNA strands are located - "sticky ends".

Stem cells against heart attack: another success

According to the authors, the positive effect of stem cells in the treatment of the consequences of myocardial infarction can be explained by the fact that they promote the regeneration of heart muscle cells, as well as stimulate the formation of new blood vessels.

Artificial leather will soon come off the assembly line

According to the developers, there are about two years left before the launch of automated production of artificial skin consisting of living cells. The estimated capacity of the production line is 5,000 units of leather per month, and the cost of one sample is less than 34 euros, which significantly exceeds existing offers.

If you don't sleep enough, you'll grow up fat!

Compliance with the regime of children's sleep can be an important, almost cost-free, measure to prevent childhood obesity.

Generics: hundreds of billions of savings

The US healthcare system has saved almost three quarters of a trillion dollars on generics over the past ten years.

Induced pluripotent stem cells: fibroblasts are optional

To create induced pluripotent stem cells, scientists used hemocytoblasts, precursors of all types of blood cells. In the process of cultivation, scientists by the method of transduction introduced reprogramming factors into them – genes whose expression is observed in embryonic stem cells.

Who does not smoke and does not drink, it is more expensive for the state to treat

Induced pluripotent stem cells without viruses

Scientists were able to induce "embryonality" in adult cells without leaving "tumor" genes in them.

Diets are different – the result is the same

By the end of the second year of observation, the weight loss in the groups of participants who were on four different diets was almost the same – about 3-4 kg. At the same time, from 14% to 15% of the participants lost at least 10% of their body weight (10-12 kg).

Measles vaccine will help cure prostate cancer

The strains of measles virus used in vaccines in an experiment on mice effectively infected and destroyed cells of inoperable prostate tumors. In the near future, the researchers plan to move on to testing the method on humans.

Bax-beta, an effective cancer cell killer

The effectiveness of Bax-beta on the mechanism of apoptosis is 100 times higher than this indicator for the related Bax-alfa and even contribute to the activation of its counterpart. Scientists have high hopes for the development of new drugs for the treatment of cancer that will selectively activate Bax-beta or stimulate its interaction with Bax-alfa.

Serial killer

Every twentieth death in the world is associated with drunk driving or diseases caused by alcohol abuse.

Children's cannabinol

The drug Epidiolex was allowed to be used in children aged two years and older for the treatment of two severe forms of epilepsy.

Computer games - a cure for insanity

At the end of the experiment, it turned out that elderly people who regularly played a strategic computer game switched from one task to another much better and faster and operated with data and stored information in memory. The logical thinking skills of the "players" were also higher.

Cryptogenomics

George Church created the startup Nebula Genomics, offering customers to receive cryptocurrency for selling their genome.

In the top ten

Evgeny Kunin, one of the most famous Russian–American molecular biologists, was among the top ten leading scientists in the field of life sciences.

Hear the light?

If no negative effects of prolonged heating are detected, then cochlear implants stimulating the neurons of the auditory nerve with infrared light will significantly improve the lives of deaf people.

Glue for fractures

It is assumed that the strength of the glue will be such that the broken bone will be stronger than the whole. Glue can also be used to deliver the necessary medicines to the fracture site, for example, antibiotics, painkillers, hormones, etc.
