Genome of Steller"s sea cow decoded
During the Ice Age, giant mammals such as mammoths, saber-toothed cats and wooly rhinoceroses once roamed Northern Europe and America. The cold oceans of the northern hemisphere were also home to giants like Steller's sea cow, which grew up to eight.....»»
How skates learned to fly through water is revealed in their genome
The little skate's dance on the ocean floor is graceful: Its massive frontal fins undulate as it skims beneath a layer of sand. With its mottled sand-colored camouflage, the animal is easy to miss......»»
When cells sense the cue for growth
Researchers of the Genome Dynamics Project team at Tokyo Metropolitan Institute of Medical Science have revealed a new mechanism controlling cellular proliferation in response to serum, which triggers growth of resting cells......»»
Study reveals the 3D structure of a protein involved in genome editing
Gene editing is one of the latest breakthroughs in biology. The widely known CRISPR-Cas gene editing system provided prokaryotes (organisms that lack cell nuclei) an immunity against foreign DNA. Since the discovery of the CRISPR gene editing technol.....»»
Euchromatin is not really open in living cells, shows study
DNA and associated proteins in active regions of the genome are condensed but behave like a viscous liquid at the molecular level. This finding greatly increases our understanding of the physical nature of expressed genome regions in living human cel.....»»
New study reveals details across 20 diverse inbred mouse strains
The completion of the full "telomere-to-telomere" (T2T) human genome last year emphasized that genome sequences that were previously thought to be "complete" were not, in fact, complete at all......»»
Jumping genes in cancer cells open door to new immunotherapies
Jumping genes are short sections of DNA that have been incorporated randomly into the human genome over the long course of evolution. Also called transposable elements, these pieces of DNA have been implicated in the development of cancer......»»
Team proposes an archetype specimen for all dingoes
A taxidermy-prepared dingo named Cooinda has been proposed to serve as an "archetype" specimen for all dingoes. A newly published article provides detailed information on this individual, including a high-quality genome sequence, other molecular biol.....»»
Toward a tastier tomato: Recovering the lost STP1 variant in modern tomato to improve soluble solid in fruit
In a study recently published in the journal Horticulture Research, researchers performed a genome-wide association study (GWAS) for SSC of the red-ripe fruits in a population consisting of 481 tomato accessions with large natural variations and foun.....»»
Understanding how cohesin makes DNA loops in the human genome and its role in Cornelia de Lange syndrome
Cohesin is a ring-shaped protein that surrounds and moves around the DNA molecule, forming the loops. It is a crucial process for the cell. Understanding how cohesin works has been one of the challenges of molecular biology in recent decades. A study.....»»
Genome of Australian fly defeats killer bacteria by evolving to co-exist with it
The more we learn about the biological world, the more complex it becomes......»»
Pseudo-chromosome–length genome assembly for the deep-sea eel Ilyophis brunneus sheds light on deep-sea adaptation
Recently, the research team led by Dr. Shunping He from the Institute of Deep Sea Science and Engineering, Chinese Academy of Sciences, published their research findings in the online version of Science China Life Sciences......»»
Study: SARS-CoV-2 can alter genome structure of our cells
People infected with SARS-CoV-2, the virus that causes COVID-19, may experience genome structure changes that not only may explain our immunological symptoms after infection, but also potentially link to long COVID, according to a new study by resear.....»»
Researchers discover a new way to fight the aging process and cancer development
A protein complex prevents the repair of genome damage in human cells, in mice and in the nematode Caenorhabditis elegans, a team of researchers at the University of Cologne has discovered. They also successfully inhibited this complex for the first.....»»
"Deep proteome" project provides atlas for human complexity
A major puzzle of biology is that while the human genome contains roughly 20,000 genes, many comparatively primitive organisms—including the universally-studied worm C. elegans—have almost the same number of genes......»»
Hunter-gatherer genes helped early European farmers survive disease, reveals study
When early Stone Age farmers first moved into Europe from the Near East about 8,000 years ago, they met and began mixing with the existing hunter-gatherer populations. Now genome-wide studies of hundreds of ancient genomes from this period show more.....»»
Beethoven’s genome, sequenced for first time, yields clues on cause of death
Composer had genetic predisposition to liver disease and hepatitis B infection. Enlarge / Portrait of Beethoven by Joseph Karl Stieler, 1820 (credit: Beethoven-Haus Bonn) Ludwig van Beethoven is one of the greatest compo.....»»
It’s Official: No More Crispr Babies—for Now
In the face of safety risks, experts have tightened the reins on heritable genome editing—but haven’t ruled out using it someday......»»
Scientists discover giant insect genome
The largest genome of any insect, seven times the size of the human genome, was recently discovered in a grasshopper. In a study published in PLOS ONE, researchers from the German Leibniz Institute for the Analysis of Biodiversity Change (LIB) and th.....»»
Inside the shark nursery: The evolution of live birth in cartilaginous fish
A new study in Genome Biology and Evolution reveals that egg yolk proteins may have been co-opted to provide maternal nutrition in live-bearing sharks and their relatives......»»
New technology maps where and how cells read their genome
A new study published in Nature reports that a technology known as spatial omics can be used to map simultaneously how genes are switched on and off and how they are expressed in different areas of tissues and organs. This improved technology, develo.....»»
