Stanford Researchers Identify 380 DNA Variants Linked to Cancer Prediction and Growth

Credit: PixabayGenetic variants regulate key genes involved in DNA repair, energy production, and immune interactions, offering fresh insights into inherited cancer risks. Surprisingly, inflammation-related genes also emerged as potential cancer drivers, marking a major step toward precise genetic screening and personalized prevention.Thousands of tiny DNA sequence changes have been linked to cancer risk, but...

DNA-Shedder Status May Impact Crime Scene Investigations

A new study shows that different people transfer different amounts of genetic material to items that they touchDepositphotosIf you’ve ever watched CSI, you know that suspects often leave incriminating DNA traces at crime scenes. However, a recent study suggests that the amount of this genetic material could also indicate a person’s guilt or innocence....

Artificial Amber Preserves DNA for Long-Term Data Storage

DNA is a much denser data storage medium than anything humans can design, but it is fragile. Scientists have now mimicked nature by creating artificial amber to protect DNA for long-term data storage.A single gram of DNA can hold up to 215 petabytes (215 million GB) of data, making it possible to store the...

Air Conditioning Units Help catch Criminals by Collecting their DNA

A recent study shows that identifiable airborne DNA can be extracted from a room's air conditioner – and in some cases, even just from the air itself. credit: PixabayEven if a perpetrator wears gloves, their DNA may still persist in the air of a room after they leave. A recent study suggests that if...

Bloodborne Pathogens Swiftly Identified by Melting their DNA

Lead scientist Stephanie Fraley works with one of the possibly infected blood samples used in the studyDavid Baillot/UC San Diego Jacobs School of EngineeringA new technique that melts bacterial DNA in blood samples could diagnose life-threatening infections faster than before.Typically, to detect harmful bacteria in a person's bloodstream, a blood sample is cultured in...

Six Indicators of Neanderthal DNA, as Identified by Genetic Experts

Humans interbred with Neanderthals and spread DNA across the world. Credit: DepositphotosNeanderthal DNA offered evolutionary advantages during environmental adaptation, yet it also introduced drawbacks, with nicotine addiction being one of the adverse effects associated with certain genesGenetic experts assert that six key indicators can reveal the presence of Neanderthal DNA.Approximately two percent of our...

Nanorobots Capable of Folding DNA can Replicate Indefinitely

Tiny nano-robots have been developed that can grab tiny snippets of DNA and assemble them into new nano-machines – including copies of themselvesAI-generated image by DALL-EResearchers have showcased a programmable nanoscale robot constructed from a few DNA strands, which can capture other DNA fragments and assemble them to produce new UV-welded nanomachines, including duplicates...

The Initial Chimeric Monkey has Surfaced, Displaying Dual Sets of DNA

Images show the green fluorescence signals in different body parts of the three-day-old chimeric monkeyCao et al/Cell/(CC By SA)In a scenario reminiscent of the initial scenes in a science fiction horror movie, scientists have injected stem cells from a seven-day-old monkey embryo into an unrelated four-to-five-day embryo of the same species. This combined embryo...

Key Players in Anaerobic Digestion for Enhanced Biogas Production

Scientists discover Darwinibacteriales, a game-changing bacteria order, revolutionizing biogas production. Potential to enhance renewable energy globally. Credit: bioRxiv (2023). DOI: 10.1101/2023.09.08.556800In a significant breakthrough, scientists from the European research project Micro4Biogas have identified a new taxonomic order of bacteria known as Darwinibacteriales, which play a crucial role in the decomposition of organic matter and have the...

DNA Found in Paw Prints Can Now Be Used to Identify Polar Bears

Credit: PixaobayGiven dire forecasts suggesting the potential extinction of polar bears by the century's close, it becomes imperative for scientists to establish a means of tracking their population to gauge the effectiveness of conservation endeavors in mitigating the impacts of rapidly disappearing habitats.However, working safely with polar bears (Ursus maritimus) is notoriously challenging due...
