And a very prominent event - the first civil Space Port Vostochniy has held the first successful launch in its history yesterday. The first Vostochniy's launch was done by Soyuz-2-1U unmanned space rocket that has brought a bunch of scientific satellites to different orbits using Volga booster:

In Siberia, researchers keen on much higher drug efficacy

27 Apr '16
Siberian scientists are developing special drug delivery agents as an answer to drugs’ currently poor bioaccessibility, or assimilability by the human body, portal Science in Siberia reported.

More than half of the drugs available across the global pharmaceutical market are poorly soluble or completely insoluble, a factor that dramatically reduces their bioaccessibility. Hence the need for considerably increased doses, which leads to side effects and takes its toll on a patient’s budget.

Researchers at the Novosibirsk-based Voevodsky Institute of Chemical Kinetics and Combustion are offering a solution to the problem which calls for the use of special delivery agents. These are chemical compounds that can form a sort of casing around drug molecules, thus boosting their dissolvability and ability to penetrate cell membranes in the body. The scientists suggest that glycyrrhizic acid, the chief sweet-tasting constituent of liquorice root, be used to come up with such compounds.

According to Dr. Nikolay Polyakov at the Institute’s magnetic phenomena lab, the approach will make it possible to increase drugs’ bioaccessibility “by a factor of 10, if not 100.”

During animal tests, using glycyrrhizic acid with blood pressure and arrhythmia drugs reportedly led to decreasing doses to negligible amounts.

What the Novosibirsk think-tank has developed may also be used to enhance the efficacy of natural antioxidants such as carotenoids (lutein and zeaxanthin). Drugs that contain the carotenoids are used to treat eye problems and improve our ability to see well.

In addition to medicines for humans the research team in Siberia is working on boosting bioaccessibility for vet solutions and agents used in plant cultivation.

At MIPT, new cooling for next gen computers developed

28 Apr '16
Physicists at Moscow’s MIPT, a leading Russian university focused on physics and technology, also known as Phystech, have developed a cooling system or the plasmon components of optoelectronic chips which are expected to run tens of thousands of times faster than today’s computers.

Their research has shown that using efficient multilayer thermal interfaces several nano- and micrometers thick in combination with conventional cooling systems can lower the temperature of a chip to a level which is just about 10 degrees Celsius above the ambient temperature. This appears to be opening much broader horizons for the use of optoelectronic chips in areas ranging from supercomputers to compact electronic devices, and traditional cooling systems reinforced with the new solution may still be widely used.

Modern computer technologies are built around electrons that move. The development of such technologies is severely hampered by physical factors that make it impossible to reduce the size of a device and lower an operating frequency.

Today, conventional electronic ICs operate about as fast as they possibly can. In fact, the ability of a computer to run faster is not only dependent on the capacity of one kernel; it hinges also on the speed of data exchange between kernels. Conventional electrical copper couplings in chips have a very limited throughput capacity, and no increase in chip capacity can be achieved with them. In simpler words, doubling the number of kernels won’t help double the capacity of your computer.

In an attempt to address the problem, physicists turned to optics, trying to replace electrons with photons. If they pull it off, the next generation of computers called optical computers will arise, capable of operating at least tens of thousands of times faster than the computers we have today.

Replacing electrons with photons is expected to enable the transmission of large volumes of data between chip kernels virtually within a split second. That’s why a large number of research teams across the world, including the leaders in the sector such as IBM, Oracle, Intel, HP and others, are working on the development of super-fast optical systems that could help retire electronic ones. Photonics is an area that already attracts billions of dollars in investment.
