Transcriptional Mutagenesis may contribute to neurodegenerative diseases, cancer, and aging
Two types of DNA damage that frequently befall most cells on an everyday basis can lead to the creation of damaged proteins that may contribute to neurodegeneration, aging and cancer, according to research by scientists at Emory University School of Medicine, published in the October 23 issue of the journal Molecular Cell.
The investigators used e. coli cells as a model system to study specific kinds of genetic damages that occur in all non-dividing cells undergoing transcription –– the everyday activity in which cells produce the proteins necessary to carry out bodily processes. The vast majority of scientists studying genetic mutations have focused instead on the cell replication process, in which damaged and unrepaired DNA within multiplying cells can be copied before cells divide and passed along to a new generation of cells. Most of the cells within organisms are no longer replicating, however, and instead spend their time manufacturing proteins.

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
