To understand the workings of DNA in relation to disease, scientists at Los Alamos National Laboratory have developed the first multimodal deep learning model of its kind, EPBDxDNABERT-2, capable of ascertaining the precise relationship between trans.....»»
New DNA evidence rewrites long-told stories of people in ancient Pompeii
When a volcanic eruption buried the ancient city of Pompeii, the last desperate moments of its citizens were preserved in stone for centuries......»»
DNA shows Pompeii’s dead aren’t who we thought they were
Integrating genetic data with historic and archaeological data can enrich or correct popular narratives. People have long been fascinated by the haunting plaster casts of the bodi.....»»
Artificial receptors made from coronavirus DNA open up new avenues for research
A team of microbiologists and virologists at Wuhan University, working with colleagues from the Chinese Academy of Sciences, the University of Washington and Humabs BioMed SA, has found that it is possible to use coronavirus DNA to create receptors t.....»»
Grocery stores are more reliable than sushi restaurants in labeling salmon properly, Seattle study finds
In a study of salmon samples from Seattle, Washington, grocery stores and sushi restaurants, DNA analysis revealed that 18% were mislabeled. Tracie Delgado and colleagues at Seattle Pacific University, WA, U.S., present these findings in the open-acc.....»»
Biologists discover how plants evolved multiple ways to override genetic instructions
Biologists at Washington University in St. Louis have discovered the origin of a curious duplication that gives plants multiple ways to override instructions that are coded into their DNA. This research could help scientists exploit a plant's existin.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Tracing the journey from Egyptian cat mummies to modern house pets
EU researchers are testing DNA from archaeological cat remains to help unravel the tale of cat domestication. It probably will not surprise cat owners, familiar with the enigmatic and independent nature of their beloved pets, to know that scientists.....»»

New insights into mango evolution: Study reveals extensive hybridization within the Mangifera genus
A research team investigated whole chloroplast genomes and nuclear gene sequences from 14 species, uncovering new insights into the genetic diversity and hybrid origins of mango species. They used the evolutionary relationships within the Mangifera g.....»»
How can you write data to DNA without changing the base sequence?
A new method lets anyone with a kit write data to DNA with just one enzyme. Zettabytes—that’s 1021 bytes—of data are currently generated every year. All of those cat videos.....»»
CRISPR-Cas10 can flood virally infected bacteria with toxic molecules, researchers discover
CRISPR-Cas9 has long been likened to a kind of genetic scissors, thanks to its ability to snip out any desired section of DNA with elegant precision......»»
Study: DNA corroborates “Well-man” tale from Norse saga
The "Well-man" likely had blue eyes, blond or light-brown hair, and hailed from southern Norway. A 12th-century Norse saga tells of an invading army from the south razing a castl.....»»
A much faster way to encode DNA with usable digital data
An international team of molecular biologists, computer scientists and physicists has found a way to encode useable digital data onto DNA strands 350 times faster than current approaches. In their study, published in the journal Nature, the group use.....»»
Through the looking glass: A cross-chiral reaction challenges our definition of life
Just like your left and right hand exist as mirror images of each other, many biological molecules have their own form of left- and right-handedness, called chirality. Our DNA, for example, is made of right-handed chiral molecules which combine to fo.....»»

Single-molecule imaging reveals aberrant DNA-binding dynamics of cancer-linked chromatin remodelers
Biophysical chemists from the National University of Singapore (NUS) have uncovered a previously hidden landscape that governs the intracellular organization and dynamics of SWI/SNF chromatin remodelers, an important class of protein complexes that c.....»»
Resolving biology"s dark matter: DNA barcoding reveals hidden insect diversity
There are millions of species on Earth that we still know nothing about. Researchers call these species "biological dark matter," but new methods can provide us with a better overview more quickly......»»
DNA-binding C2H2 zinc finger proteins also regulate RNA processing, researchers discover
Researchers at the University of Toronto have shown that an important class of DNA-binding factors can also bind to RNA, regulating gene expression through various mechanisms. The study significantly expands our understanding of these proteins' funct.....»»
Environmental DNA and epidemics in wood frogs: Collaboration examines eDNA"s precision in population size estimation
Tracy Rittenhouse, associate professor of natural resources and the environment in UConn's College of Agriculture, Health and Natural Resources (CAHNR), was doing an experiment to study ranavirus epidemics in wood frogs. When Meghan Parsley, then a P.....»»
