Genetic identification of species through ‘metabarcoding’ offers a reliable, cost-effective way of producing biodiversity information for policymakers and managers, concludes an international study. The researchers show how the method can be used to help assess the impacts of environmental change and management on biodiversity.

Scientists have developed a new way of monitoring Ponto-Caspian gobies, a group of widely invasive fish species, by detecting traces of the fishes’ DNA in river water. They say, in a recent research paper, that it offers a quicker, easier and cheaper way of monitoring the fish than conventional catching or sighting methods.

A survey of deepwater fisheries off the coast of Greenland which used traces of fish DNA has produced similar results to trawl surveys and fishing catches. The ‘environmental DNA’ (eDNA) technique can therefore complement trawl data, the researchers say. It may be particularly useful for surveying large species — which can often avoid bottom trawls — or cryptic species1 in inaccessible ocean areas.

A study in the Czech Republic has found a link between exposure to certain air pollutants and an increase in DNA damage for people exposed to high levels of the pollution. They found that breathing small quantities of a polycyclic aromatic hydrocarbon (PAH), called benzo[a]pyrene (B[a]P), caused an increase in the number of certain ‘biomarkers’ in DNA associated with a higher risk of diseases, including cancer.

Traces of animals’ DNA in the environment, known as environmental DNA (eDNA), can be monitored to paint a picture of biodiversity, new research shows. This study used eDNA to assess biodiversity in an entire river catchment in Switzerland. Importantly, the eDNA technique allowed the researchers to detect both aquatic and land-based species in river water, making it possible to assess biodiversity over a broad scale.

A method for encoding information in DNA sequences is described. The method is based on the precision-resolution framework, and is aimed to work in conjunction with a recently suggested terminator-free template independent DNA synthesis method. The suggested method optimizes the amount of information bits per synthesis time unit, namely, the writing rate. Additionally, the encoding scheme studied here takes into account the existence of multiple copies of the DNA sequence, which are independently distorted. Finally, quantizers for various run-length distributions are designed.

A cytosine analog, a method of preparation of a cytosine analog, a DNA methyltransferase 1 inhibitor, and a method for DNA methylation inhibition, is provided for the treatment of diseases associated with deviations from normal DNA methylation. The analog of cytosine may be comprised of 1, N4, 5 and 6-substituted derivatives of cytosine or 5,6-dihydrocytosine, wherein the analog can be described by the chemical formula where R1 is H, R3, R4, 2'-deoxyribosyl, R4 is alkyl or aryl, X is N or C, wherein if X in the analog of formula I is N, then R5 is no substituent and if X in the analog of formula I and/or II is C or if X in the analog of formula II is N, then R5 and R6 are independently alkyl, aryl, hydroxyalkyl, aminoalkyl, hydroxyl, carboxyl, amino group, alkoxyl, aryloxyl, aminoalkyl, aminoaryl, thio group, sulfonyl, sulfinyl or halogen.

Plant viral vectors have great potential in rapid production of proteins, but no simple. Here a geminivirus-based system for high-yield and rapid production of oligomeric protein complexes, including virus-like particle (VLP) vaccines and monoclonal antibodies (mAbs) is described. In particular, a single vector that contains two non-competing replicons for transient expression in Nicotiana benthamiana leaves is described. The correct assembly of these subunit proteins into functional oligomeric structures (VLPs or full-size mAb) is also described. This system advances plant transient expression technology by eliminating the need for non-competing viruses, and thus, enhances the realistic commercial application of this technology for producing multiple-subunit protein complexes.

The present invention relates to a novel method for analyzing nucleic acid sequences based on real-time detection of DNA polymerase-catalyzed incorporation of each of the four nucleotide bases, supplied individually and serially in a microfluidic system, to a reaction cell containing a template system comprising a DNA fragment of unknown sequence and an oligonucleotide primer. Incorporation of a nucleotide base into the template system can be detected by any of a variety of methods including but not limited to fluorescence and chemiluminescence detection. Alternatively, microcalorimetic detection of the heat generated by the incorporation of a nucleotide into the extending template system using thermopile, thermistor and refractive index measurements can be used to detect extension reactions.
