Native bittering fish, Tanakia lanceolata
04 Jan 2021
Reproduction of native and invasive bitterling fishes and their hybridisation was studied in Japan. We collected mussels in which these bitterlings lay their eggs, kept them in aquaria, collected eggs/larvae ejected from mussels, and genotyped them. We found that hybrids occurred when local mussel density was low. The rapid decline of the host mussels and artificial introduction of an invasive congener interacted to cause the rapid decline of a native fish.

Tohoku University scientists have, for the first time, provided experimental evidence that cell stickiness helps them stay sorted within correct compartments during development. How tightly cells clump together, known as cell adhesion, appears to be enabled by a protein better known for its role in the immune system. The findings were detailed in the journal Nature Communications.

Researchers at WPI-IIIS find that normal sleep in mice depends on bacteria that help make neurotransmitters such as serotonin in the gut. The article, “Gut microbiota depletion by chronic antibiotic treatment alters the sleep/wake architecture and sleep EEG power spectra in mice,” was published in Scientific Reports.

A transporter protein that regulates cell membrane cholesterol likely played an important role in vertebrate evolution, according to a review published by iCeMS researchers in the journal FEBS Letters.
BioAFMviewer
22 Dec 2020
Atomic force microscopy (AFM) allows to obtain images and movies showing proteins at work, however with limited resolution. The developed BioAFMviewer software opens the opportunity to use the enormous amount of available high-resolution protein data to better understand experiments. Within an interactive interface with rich functionality, the BioAFMviewer computationally emulates tip-scanning of any biomolecular structure to generate simulated AFM graphics and movies. They greatly help in the interpretation of e.g., high-speed AFM observations.

Scientists release genetic results confirming a female turtle captured in October 2020 in Viet Nam is definitively the near extinct Swinhoe’s softshell turtle (Rafetus swinhoei) – also known as the Yangtze giant softshell turtle and Hoan Kiem turtle.
New IRAK4 mutations discovered

Daegu Gyeongbuk Institute of Science and Technology (DGIST) researchers gain deeper insight into a cell membrane channel, with potential implications for drug development.
Relationship between OHC levels and transcriptome profiles in salmon collected from three areas of the Baltic Sea
16 Dec 2020
Researchers of Ehime University and the University of Helsinki measured hepatic organohalogen (OHC) concentrations and gene expression profiles in Atlantic salmon collected from three areas in the Baltic Sea. The results showed that OHCs and gene expression profiles were individually grouped in three areas and the covariation of the two datasets provided by a multivariate method was significantly similar. This suggests that the gene expression profiles in salmon are affected by OHC contamination.

Recognizing species is important for understanding regional biodiversity and for environmental conservation. However, taxonomic identity is sometimes obscure even with the organisms that are closest to human life.
Turning off gene editing during error-prone cell cycle phases

Turning off gene-editing until it reaches cell cycle phases where more accurate repairs are likely to happen offers a promising fix to CRISPR-Cas9’s problem with unwanted genetic changes.

A research team, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has succeeded in unveiling the principle behind the changing sleep patterns, according to the ambient temperature, through the use of Drosophila as a model of sleep.
When researchers inhibited Wnt signalling the anti-cancer drug ETC-159, they found that the reactivation of the hyperactive RAS-MAPK pathway led the cancer cells to undergo senescence, which is an ageing process that results in arrested growth.

Cancer is a disease driven by mutations that alter the way biochemical signals control cell growth, division and migration. Scientists at Duke-NUS Medical School found out that, like Goldilocks, cancer is very picky about getting rapid growth just right.

Image for sedimentary DNA analysis

Far too little is known about the long-term dynamics of the abundance of most macro-organism species. We used sedimentary DNA technology to quantify marine fish DNA abundance in sediment sequences spanning the last 300 years. This study first shows the existence of fish DNA in the sequences and proves that fish abundance can be tracked using sedimentary DNA, highlighting the utility of sedimentary DNA for researchers to acquire lengthy records of macro-organism species abundance.
