Unraveling DNA packaging
Researchers report how high-speed atomic force microscopy can be used for studying DNA wrapping processes. The technique enables visualizing the dynamics of DNA-protein interactions, which in certain cases resembles the motion of inchworms......»»
New AI model improves prediction power for genomics related to disease
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.....»»
Sustainable hydrophobic cellulose shows potential for replacing petroleum-related products
A recent study has aimed to create hydrophobic paper by exploiting the mechanical properties and water resistance of cellulose nanofibers, and so produce a sustainable, high-performance material suitable for packaging and biomedical devices. This inv.....»»
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.....»»

Paper-aluminum combo can replace plastic for strong, sustainable packaging
Takeout containers get your favorite noodles from the restaurant to your dining table (or couch) without incident, but they are nearly impossible to recycle if they are made from foil-lined plastics. Research published in ACS Omega suggests that repl.....»»
Are bioplastics really the wonder alternative to petro plastics?
Alternatives to petrochemical-based plastics are emerging, made from everything from banana leaves to tomato skins, especially for food packaging......»»
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......»»
