When your body's cells produce energy, they also create byproducts called reactive oxygen species (ROS). These can damage DNA in various ways, one of the most common being the oxidation of guanine, a building block of DNA. This oxidized form is known as 8-oxoguanine (8-oxoGua). If not fixed, 8-oxoGu
Marek's Disease, a significant health issue for chickens, can cause neurological damage and tumors. It heavily impacts the poultry industry's economy and animal welfare. In the past, scientists used individual genotyping to map regions linked to MD on chicken autosomes. This time, they used a differ
Ever wondered why some plant DNA extraction kits give you better results than others? It all comes down to how well they handle the DNA, especially for those tiny little plants. Scientists use these kits to study the genetic material of plants, and the quality of the DNA they get can make or break t
Cancer has this unique friend called telomerase, which is pretty active in cancer cells. Telomerase is like a tiny machine with a reverse transcriptase and something called human telomerase RNA (hTR). We usually spot telomerase by its activity in tissues or single cells, but that's not the whole sto
You know how solving crimes often depends on finding and identifying body fluid stains? Well, scientists are making this task easier with the help of AI and a method called DNA methylation microarray screening. This process allows them to spot specific CpGs, which are tiny segments of DNA, in body f
In a New Jersey murder trial, a software called STRmix is under scrutiny. This software helps analyze complex DNA samples that used to be considered unusable. Defense lawyers for Paul Caneiro, accused of killing four family members, argue the software isn't reliable enough for court. They say it was
DNA isn't just a straight line of code; it's a twisted, intertwined helix. This twist, or DNA topology, affects almost every DNA reaction in living cells. The key players managing this twist are DNA topoisomerases. While we’ve learned a lot about these enzymes in bacteria and more complex life forms
Scientists looked into how religion and spirituality affect DNA methylation in stress-related genes among Latino adults. They studied 992 people from the Hispanic Community Health Study and focused on four key genes linked to the hypothalamic-pituitary-adrenal (HPA) axis, which regulates stress resp
Imagine having mini detectives in your body that light up when they find what they're searching for. Scientists have made this possible with special DNA fragments called FLAPs. When these FLAPs meet specific substances, they glow brightly. Out of many, two particular FLAPs were found to change color
In an incredible turn of events, a jury convicted a 67-year-old man last week for a 1994 kidnapping at the Oakridge Mall, thanks to a cold-case investigation that relied on DNA evidence. Thomas John Loguidice was found guilty of felony kidnapping with the intent to rob, after he was linked to the cr
