Recently, a new mutation signature found in cancer cells was suspected to have been created by a family of enzymes found in human cells called the APOBEC3 family. The study, 'Strand-biased Cytosine deamination at the Replication Fork causes Cytosine to Thymine Mutations in Escherichia coli,' led by Ashok Bhagwat, Ph.D., professor of chemistry in the College of Liberal Arts and Sciences at Wayne State University, was recently published in the Proceedings of the National Academy of Sciences.
Seismic, deformation, and gas activity (unrest) typically precedes volcanic eruptions. Tracking the changes of this activity with monitoring data makes it increasingly possible to successfully forecast eruptions from stratovolcanoes. However, this is not the case for monogenetic volcanoes (usually the result of a single magmatic pulse). Eruptions from these volcanoes tend to be small but are particularly difficult to anticipate since they occur at unexpected locations, and there is very limited instrumental monitoring data.
An engineering research team at the University of Alberta has invented a new transistor that could revolutionize thin-film electronic devices. Their findings, published in Nature Communications, could open the door to the development of flexible electronic devices with applications as wide-ranging as display technology to medical imaging and renewable energy production. The transistor is easily scaled and has power-handling capabilities at least 10 times greater than commercially produced thin film transistors.
A USC-led team of researchers have hope that behavioral interventions could help doctors slow the rise of treatment-resistant infections in hospitals and clinics, reduce adverse drug events in patients, and lower health care costs.
Researchers at the French National Centre for Scientific Research, CNRS, and the University of Lorraine have recently developed a design for a coiled-up acoustic metasurface which can achieve total acoustic absorption in very low-frequency ranges.
Iowa State's Zengyi Shao and Jean-Philippe Tessonnier are combining the tools of biology and chemistry to create new biorenewable products. Their hybrid conversion technology is featured on the cover of the Feb. 12 issue of the journal Angewandte Chemie International Edition.
A team at Cold Spring Harbor Laboratory has discovered the purpose of a highly conserved genetic tool that is present in both mosses and flowering plants, organisms whose common ancestor dates back 450 million years. As they report in Developmental Cell, the gene network, which comprising a snippet of non-coding genetic material called a small RNA and the protein it regulates, has been used over the eons to make plants more sensitive to environmental cues and facilitate robust, yet flexible, responses to those cues.
A new study co-authored by an MIT professor shows that China's new efforts to price carbon could lower the country's carbon dioxide emissions significantly without impeding economic development over the next three decades.
An international team of scientists led by the University of Liverpool has produced a 'structural movie' revealing the step-by-step creation of an important naturally occurring chemical in the body that plays a role in some cancers.
Indications of light-induced lossless electricity transmission in fullerenes contribute to the search for superconducting materials for practical applications
