April 30, 2021
Led by Johns Hopkins University, a team of 10 researchers from three institutions is using a new $4 million, five-year grant from the National Science Foundation to create a next-generation turbulence database that will enable groundbreaking research in engineering and the atmospheric and ocean sciences.
This powerful tool will let researchers from all over the world access data from some of the largest world-class numerical simulations of turbulent flows. Such simulations are very costly and their outputs are traditionally very difficult to share among researchers due to the data sets massive size. ....

Study reveals molecular mechanisms of drug resistance in Mycobacterium tuberculosis

Study reveals molecular mechanisms of drug resistance in Mycobacterium tuberculosis
A consortium of researchers from Russia, Belarus, Japan, Germany and France led by a Skoltech scientist have uncovered the way in which Mycobacterium tuberculosis survives in iron-deficient conditions by utilizing rubredoxin B, a protein from a rubredoxin family that play an important role in adaptation to changing environmental conditions.
The new study is part of an effort to study the role of
M. tuberculosis enzymes in developing resistance to the human immune system and medication. The paper was published in the journal
Bioorganic Chemistry.
According to the World Health Organization, every year 10 million people fall ill with tuberculosis and about 1.5 million die from it, making it the world s top infectious killer. The bacterium that causes TB, Mycobacterium tuberculosis, is notorious for its ability to survive within macrophages, cells of the immune system that destroy ....

Mass Spectrometry Helps Identify Molecular Composition of Meteorites

Mass Spectrometry Helps Identify Molecular Composition of Meteorites
Written by AZoOpticsApr 6 2021
In an effort to find the origin of carbonaceous chondrites the insoluble organic matter constituting the Murchison and Allende meteorites researchers from Russia and Germany investigated their molecular composition.

Using ultra-high resolution mass spectrometry, the team unraveled an extensive diversity of chemical compositions and unpredicted similarities between meteorites from various groups. The study has been published in the journal
Scientific Reports.
Carbonaceous chondrites are made of almost the whole spectrum of organic molecules found on Earth, such as nucleic acids that could have had a crucial role in the evolution of life. ....

Skoltech team used mass spectrometry to study composition of meteorites

Scientists from Russia and Germany studied the molecular composition of carbonaceous chondrites - the insoluble organic matter of the Murchison and Allende meteorites - in an attempt to identify their origin. Ultra-high resolution mass spectrometry revealed a wide diversity of chemical compositions and unexpected similarities between meteorites from different groups. The research was published in the
Scientific Reports.
Carbonaceous chondrites contain nearly the entire spectrum of organic molecules encountered on Earth, including nucleic acids which might have played a pivotal role in the origin of life. Since the majority of modern meteorites are of nearly the same age as the Earth, their composition should be similar to that of meteorites that bombarded the Earth s surface in ancient times. Just like comets, they can be considered a source of organic compounds which most likely formed the core of the Earth s biosphere. ....
