Protiivny pheromone

Flies deprived of the 7-T pheromone were more attractive to potential sexual partners. Moreover, representatives of both sexes tried to mate with them. In addition, such fruit flies became attractive to flies of other species.

Gene therapy against HIV/AIDS success inspires

The technique developed by scientists at the California Institute of Technology was called "opacity suppression by optical reversal of the wavefront" (turbidity suppression by optical phase conjugation, TSOPC).

Nanoparticles for cancer treatment: the more, the better

Iron oxide nanoparticles coated with polysaccharides proved to be more effective in the treatment of cancerous tumors than similar, but smaller ones.

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.

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.

Long-acting analgesic: the same as usual, but in liposomes

Researchers from Harvard Medical School proposed to inject the drug for local anesthesia saxitoxin in combination with the steroid hormone dexamethasone into liposomes. In this form, one injection for a week blocked the conduction of impulses along the sciatic nerve.

The main breakthrough

In the annual top 10 discoveries that influenced the development of science, Science magazine called the creation of coronavirus vaccines a major breakthrough.

Day of the Elderly

On the first day of October in Russia, as in many other countries of the world, the International Day of the Elderly is celebrated.

Nanodrugs from the crisis

The Finnish Agency for Technology and Innovation Financing Tekes has simplified the procedure for issuing grants to developers. Russian companies can claim the money.

Stem Cell Registry: St. Petersburg, 2012

By 2012, 10,000 stem cell samples should be harvested. Such a bank, according to doctors, will greatly simplify the treatment of hematological diseases – for example, leukemia.

Induced pluripotent stem cells without viruses

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

Anti-obesity remedy: electronically tested :)

Preliminary clinical trials have shown that EndoBarrier leads to the same effect as surgical gastric reduction. Obese subjects who tested the device experienced rapid weight loss while maintaining their usual food intake.

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.

Managed transgenics

The activity of transgenes can be controlled by heat and ultrasound.

Serial killer

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

Another danger of chemotherapy

Chemotherapy can lead to amenorrhea and early menopause in women with lung cancer.
