Breakthrough technique unveils secrets of "backtracking" in gene regulation

A technique can determine for the first time how frequently, and exactly where, a molecular event called "backtracking" occurs throughout the genetic material (genome) of any species, a new study shows.

Structural analysis of monkeypox virus to guide the development of broad antiviral agents

In a new study, researchers explored the crystalline structure of the monkeypox (MPX) virus (MPXV) and the complex of VP39, a 2′-O-RNA methyltransferase (MTase) and sinefungin, a pan-MTase inhibitor.

Study shows how RNA editing affects the replication of COVID-19 virus

Two human deaminase enzymes edit the RNA of the SARS-CoV-2 virus when it enters a patient's body, with implications for the evolution of the virus and the spread of the infection, according to a new study.

Researchers develop technology to create hybrid catalyst from rhodium and organic catalysts

A group of Japanese researchers has developed a technology to create a hybrid catalyst from simple-structured, commercially available rhodium and organic catalysts, which reduces chemical waste and produces molecules with high selectivity of an enantiomer, a pair of molecular structures that are non-superimposable mirror images of each other.

New single probe method provides PCR-free detection of microRNA linked to liver toxicity

Quanterix Corporation, a company digitizing biomarker analysis with the goal of advancing the science of precision health, and DestiNA Genomics Ltd, a manufacturer of patented reagents for nucleic acid detection, today announced that PLOS ONE has published a proof-of-concept single probe method for detecting microRNA biomarkers associated with liver toxicity.

Scientists create method for mapping genome-wide DNA damage caused by chemical carcinogen

Scientists have known for decades that smoking cigarettes causes DNA damage, which leads to lung cancer. Now, for the first time, UNC School of Medicine scientists created a method for effectively mapping that DNA damage at high resolution across the genome.

Swiss researchers discover potential way to design new antibiotics

Two Swiss research teams from the University of Bern and the ETH Zurich have developed a new method to shed light onto a mostly unknown process of bacterial protein production. Their results could be used for the design of new antibiotics.

New TSRI study offers surprising twist on how life began on Earth

A new study led by scientists at The Scripps Research Institute (TSRI) offers a twist on a popular theory for how life on Earth began about four billion years ago.

NIST researchers simulate new method for fast, precise DNA sequencing

Researchers at the National Institute of Standards and Technology (NIST) have simulated a new concept for rapid, accurate gene sequencing by pulling a DNA molecule through a tiny, chemically activated hole in graphene--an ultrathin sheet of carbon atoms--and detecting changes in electrical current.

Unnatural DNA bases: an interview with Professor Floyd E. Romesberg, The Scripps Research Institute

The natural DNA bases that form the letters of DNA are usually referred to as G, C, A, and T. Those are only the first letters of the chemical names. They’re often called nucleotides by their scientific name and all of them have in common a phosphate part, a sugar part and a nucleobase part.

Protein M: an interview with Rajesh Grover, PhD, senior staff scientist, Lerner laboratory, TSRI

Protein M is a cell surface protein from Mycoplasma Genitalium that binds to all human antibodies.

Research may offer clues to why esophageal adenocarcinomas rates have increased rapidly

During the past 30 years, the number of patients with cancers that originate near the junction of the esophagus and stomach has increased approximately 600 percent in the United States. The first extensive probe of the DNA of these esophageal adenocarcinomas has revealed that many share a distinctive mix-up of letters of the genetic code, and found more than 20 mutated genes that had not previously been linked to the disease.

Researchers develop new method for producing image of individual DNA molecules' genetic make-up

A completely new method for producing an image of individual DNA molecules' genetic make-up has been developed by researchers in Sweden and Denmark. The results are published in the latest issue of the journal Proceedings of the National Academy of Sciences of the USA (PNAS).

Scientists create simple chemical system that mimics DNA

A team of Scripps Research scientists has created a new analog to DNA that assembles and disassembles itself without the need for enzymes. Because the new system comprises components that might reasonably be expected in a primordial world, the new chemical system could answer questions about how life could emerge.
