Siberian researchers have developed a biologically active sorbent of a new generation. The sorbent provides for the 100-percent efficient water purification from microorganisms and bacteriophages. Microbiological researches were performed with partial support of the U.S. Civilian Research and Development Foundation (CRDF) grant.
Specialists of the Tomsk Polytechnical University and Scientific Research Institute “Microorganism Culture Collection” (VECTOR State Research Center for Virology and Biotechnology) have developed a biologically active sorbent of a new generation based on cotton pulp, modified 1-percent silica slip containing activated alumina. The sorbent provides for the 100-percent efficient water purification from microorganisms and bacteriophages, it can be applied in a wide range of conditions and possesses sufficient durability and longevity.
Water and aqueous solutions are overfilled with pathogens, viruses and toxins, which so far threaten life and health of people, regardless of undertaken actions. Water purification via filtering is ineffective and underproductive, as fine filters with low throughput capacity have to be utilized. Contemporary purification methods are based on the fact that the majority of bacteria and viruses are negatively charged, therefore they can be captured by a macroporous material possessing positive electrokinetic potential. As a result of the process called electrokinetic capturing, small particles would simply stick to filter material.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
