Silencing in action: How cells 'repress' genomic remnants of ancient viruses

Sciencedaily.com 

It is crucial for organisms to be able to control which genes are expressed in which cells and when. Naturally occurring chemical modifications of DNA-binding histone proteins are believed to play an important role in this process; however, it had been unclear whether they play a causal role in instructing gene expression. Researchers have experimentally shown that certain histone sites act as critical control sites that help prevent the spurious activation of parts of the genome, including sequences derived from ancient remnants of viruses.

Scientists have shown that a type of qubit whose architecture is more amenable to mass production can perform comparably to qubits currently dominating the field. With a series of mathematical analyses, the scientists have provided a roadmap for simpler qubit fabrication that enables robust and reliable manufacturing of these quantum computer building blocks.

PBA: TNT can’t look ahead to quarterfinals just yet, says Chot

New Alzheimer's studies reveal disease biology, risk for progression, and the potential for a novel blood test

Sciencedaily.com 

Two new papers by a team of researchers demonstrate that evaluating microRNAs in blood can be used not only to diagnose mild cognitive impairment (MCI) but also, critically, to predict the conversion from MCI to dementia due to Alzheimer's disease. Moreover, the researchers uncovered microRNA candidate molecular biomarkers that associate with current Amyloid, Tau, and Neurodegeneration (A/T/N) Alzheimer's biomarkers.
