Exploring a massive supercomplex in mitochondria comprising all four respiratory complexes

Posted by in categories: biotech/medical, chemistry


Eukaryotes generate the energy for survival through cellular respiration in mitochondria by a process known as the oxidative phosphorylation. In this process, nutrients and oxygen are converted into a chemical form of energy: ATP. This is achieved with a proton gradient built up by the electron transport chain inside mitochondria.

Study investigates diffuse emission from the Cigar Galaxy

Posted by in categories: energy, space

Using NASA’s Chandra spacecraft, an international team of astronomers has performed X-ray observations of the Cigar Galaxy. Results of the observational campaign, presented March 16 on the pre-print repository arXiv, deliver crucial information regarding diffuse emission from this galaxy.

Discovered in 1,774, Cigar Galaxy (Messier 82, or M82) is a located some 11.73 million away in the constellation Ursa Major. It has a size of about 40,800 light years and is one of the closest starburst to Earth.

Observations of the Cigar Galaxy have found that it experiences a large-scale galactic wind at various wavelengths, for instance, in hard X-rays above a few keV. This superwind appears to be concentrated in the galaxy’s two high surface brightness regions or clumps, and is fueled by energy released by supernovae within the clumps that occur at a rate of about one every ten years. Previous Chandra studies of this galaxy have detected bright X-ray binaries that dominate the hard X-ray band and revealed that there is residual diffuse emission surrounding the starburst disk.

Chinese Scientists Discover Water Reservoir on the Moon

Posted by in category: space travel

Due to its potential for in-situ resource utilization by future lunar exploration missions and other space missions, lunar surface water has attracted significant attention.

Now, a research group led by Prof. Sen Hu from the Institute of Geology and Geophysics (IGG) of the Chinese Academy of Sciences (CAS) has found that impact glass beads in Chang’e-5 (CE5) lunar soils contain some water.

Detailed studies show that these glass beads are likely a new water reservoir on the Moon, recording the dynamic ingress and egress of solar wind-derived water and acting as a buffer for the lunar surface water cycle.
