Extensive sequence divergence found between reference genomes of two zebrafish strains
Tuebingen and AB are the two most common laboratory zebrafish strains. A research group led by Prof. He Shunping from the Institute of Hydrobiology (IHB) of the Chinese Academy of Sciences reported a high-quality de novo genome assembly of the AB str.....»»
Fish-on-Chips: An optofluidic platform to investigate the neural and chemosensory axes of zebrafish
Neuroscientists study chemosensory processing by establishing chemical cues and the corresponding behavioral responses to record large-scale neuronal activity. In a new report now published in Nature Communications, Samuel Sy and a team of scientists.....»»
New species of ultrasmall microalgae found in home aquarium could have multiple useful applications
A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers from the University of Tokyo discovered a DNA sequence that didn't match any on record. This new species is the smalles.....»»
The best ergonomic keyboards for 2023
If extensive typing hurts your wrists, an ergonomic keyboard can make all the difference. They offer a more natural typing position and encourage good posture......»»
Power of cancer drugs may see boost by targeting newly identified pathway
Cells zealously protect the integrity of their genomes, because damage can lead to cancer or cell death. The genome—a cell's complete set of DNA—is most vulnerable while it is being duplicated before a cell divides. Cancer cells constantly are di.....»»
Researchers uncover new potential for ancient mint plants
MSU researchers have traced the evolution of mint genomes for potential future applications that range from medicines to pesticides to antimicrobials......»»
Origin of endothelial cells constituting the vascular niche for hematopoietic stem and progenitor cells in zebrafish
Endothelial cells (ECs) line blood vessels and can serve as specialized vascular niches for hematopoietic stem and progenitor cells (HSPCs), a special environment where HSPCs reside and self-renew. A team of researchers found that endoderm-derived EC.....»»
Microbes could be used by farmers as natural fertilizer for poor soil
A study published in The ISME Journal identified 522 genomes of archaea and bacteria associated with the roots and soil of two plant species native to the Brazilian montane savanna ecoregion known as campos rupestres ("rocky meadows"). Hundreds of mi.....»»
Linux malware hit a new high in 2022
The number of detected Linux malware strains grew by 50% year-on-year as its popularity grew hugely......»»
DNA from domesticated chickens is tainting genomes of wild red junglefowl, finds study
The red junglefowl—the wild ancestor of the chicken—is losing its genetic diversity by interbreeding with domesticated birds, according to a new study led by Frank Rheindt of the National University of Singapore published January 19 in the journa.....»»
New "chain mail" material of interlocking molecules is tough, flexible and easy to make
University of California, Berkeley, chemists have created a new type of material from millions of identical, interlocking molecules, that for the first time allows the synthesis of extensive 2D or 3D structures that are flexible, strong and resilient.....»»
New study illustrates a changing flood recipe for Las Vegas
Las Vegas, with its rapid urbanization and desert landscape, is highly vulnerable to flooding. For this reason, flood managers have built an extensive system of drainage ditches and detention basins to protect the public. Now, a new study shows how i.....»»
From octopus to elephant: A molecular zoo of epigenetics
Our genes are encoded in the DNA sequence of the genome, which is highly similar across the diverse cell types of our body. Yet, each cell can only access those genes that are in an epigenetically permissive state. The epigenome thus provides a form.....»»
Joint effort discloses deep divergence of a mysterious porpoise
The finless porpoise, a relative of dolphins and whales, is native to the Indian and Pacific oceans, as well as the freshwater habitats of the Yangtze River basin in China. The Yangtze river's finless porpoise is one of the very few porpoises that li.....»»
SRM 915c calcium carbonate mass fraction standard
This standard reference material from the National Institute of Standards and Technology (NIST) will help calibrate procedures for calcium determinations used in clinical analysis and for routine critical evaluation of the daily working standards app.....»»
Standard reference cantilevers for atomic force microscopy spring constant calibration
Atomic force microscopy (AFM) is a popular technique for interrogating surfaces on the micro and nano scales. The most common use for AFM is imaging; however, there are a variety of more specialized AFM techniques that can be used to determine electr.....»»
Researchers produce first-ever toolkit for RNA sequencing analysis using a "pantranscriptome"
Analyzing a person's gene expression requires mapping their RNA landscape to a standard reference to gain insight into the degree to which genes are "turned on" and perform functions in the body. But researchers can run into issues when the reference.....»»
Marriage rules in Minoan Crete revealed by ancient DNA analysis
An international team of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, reports completely new insights into Bronze Age marriage rules and family structures in Greece. Analyses of ancient genomes show tha.....»»
Team streamlines DNA collection and analysis for wildlife conservation
A new DNA-collection approach allows scientists to capture genetic information from wildlife without disturbing the animals or putting their own safety in jeopardy. The protocol, tested on elephant dung, yielded enough DNA to sequence whole genomes n.....»»
Reference to xrOS found in Apple Devices for Windows app preview
Preview versions of Apple Music, Apple TV, and Apple Devices for Windows apps have been discovered in the Microsoft Store, and hidden in the code are references to Apple's upcoming mixed-reality operating system.A render of a potential Apple headset.....»»
Abnormal RNA gums up the works in brain cells, shows study
Our DNA contains four types of molecules, adenine, cytosine, thymine, and guanine—called nucleotides or bases—running along the strands that make up our chromosomes. Since there are only four, it is not unusual to find a short sequence of DNA rep.....»»
