Scientists have been making nanoparticles out of DNA strands for two decades, manipulating the bonds that maintain DNA’s double-helical shape to sculpt self-assembling structures that could someday have jaw-dropping medical applications.Four DNA nanostructures, two butted up against each other, highlighted in this electron microscope image. The structures are a little longer than 50 nanometers. A...

POSTED BY ANDY FELL-UC DAVIS Researchers have identified a protein linked to metastasis in pancreatic cancer. Pancreatic cancer is the No. 3 cause of cancer-related deaths in the United States, and only 12% of patients survive five years after being diagnosed. Severe pancreatic cancer is associated with metastasis, and it is this spread of secondary tumors...
Watery diarrhea can result from infections, medications, or chronic conditions. Treatments may include drinking plenty of water, avoiding foods that make it worse, and taking medications to treat diarrhea or an underlying condition. Most cases of diarrhea in adults are not serious and resolve on their own in a few days. Home care can help...

DOI: 10.3390/diagnostics13020292Scientists have developed a deep learning (DL) model capable of quickly and accurately distinguishing between monkeypox and chickenpox skin lesions, which often exhibit striking similarities. People developing pox-like rashes are normally confused about whether they are caused...

Known as “double sequential external defibrillation” (DSED), it will change initial emergency response strategies and potentially improve...
by University of South Australia Credit: Pixabay/CC0 Public DomainFor children’s sports, there’s no doubt that parents are essential—they’re the free ferry service, the half-time orange supplier, and the local cheer squad. But when it comes to sideline behavior, some parents can behave badly, and when this happens it’s often a case of “monkey see, monkey do.”...
by Katherine Gombay, McGill University Credit: Pixabay/CC0 Public DomainHydrogels are engineered materials that absorb and retain water and are currently used in various medical treatments, including dressing wounds. The problem with current hydrogels is that they adhere indiscriminately to all surfaces, which means that wound dressing can potentially damage delicate tissue as it is healing. McGill...
