CHD4 is a protein that helps rearrange DNA inside cells, making it easier or harder for genes to speak. It works as part of a larger team called NuRD, which uses energy from ATP to shuffle chromatin. When the cell faces damage, CHD4 steps in at the break sites to help rebuild and decide which
A woman in San Rafael was killed on 1 Feb 1966. Her husband, a banker, had just left for surgery, so the victim was alone when an unknown intruder entered. Investigators found three Salem cigarettes in a table ashtray – the victim never smoked that brand, so they kept them as evidence. Back then, p
DNA is not a straight stick; its shape changes with the chemicals around it. Scientists have long known that normal salt can tighten DNA, making it shorter by shielding charges or pulling strands together. Recently, a different group of salts called ionic liquids has been shown to do the oppos
Scientists from Texas A&M examined what happens when men eat large amounts of two common antioxidants – N‑acetyl‑L‑cysteine and selenium – for six weeks. The fathers looked healthy, but their pups showed clear differences in skull shape and eye spacing. The research was published in Frontiers in

Proteins are like tiny messengers in our body. They play a big role in diseases, drugs, and research. So, spotting them quickly and accurately is super important. There's a cool new way to do this using something called microscale thermophoresis (MST). It's like a heat wave that helps us see these p
In the quiet of a Tucson neighborhood, a single glove has become a crucial clue in the mysterious disappearance of 84-year-old Nancy Guthrie. This isn't just any glove; it's one that might be linked to a masked figure caught on camera near her home. The FBI has confirmed that DNA from this glove cou
