SARS‑CoV‑2, the virus that causes COVID-19, continues to mutate, with some newer strains becoming less responsive to current antiviral treatments like Paxlovid. Now, University of California San Diego scientists and an international team of researchers have identified several promising molecules that could lead to new medications capable of combating these resistant variants. Instead of [...]
According to a new study, lower doses of approved immunotherapy for malignant melanoma can give better results against tumors, while reducing side effects. This is reported by researchers at Karolinska Institutet in the Journal of the National Cancer Institute. "The results are highly interesting in oncology, as we show that a lower dose of an immunotherapy drug, [...]
Microplastics could be fueling neurodegenerative diseases like Alzheimer's and Parkinson's, with a new study highlighting five ways microplastics can trigger inflammation and damage in the brain. More than 57 million people live with dementia, and cases of Alzheimer's and Parkinson's are projected to rise sharply. The possibility that microplastics could aggravate or accelerate these [...]
Scientists have developed tiny metal-oxide particles that push cancer cells past their stress limits while sparing healthy tissue. An international team led by RMIT University has developed tiny particles called nanodots, crafted from a metallic compound, that can destroy cancer cells while largely preserving healthy ones. Although the research is still limited to cell cultures and [...]
Researchers found that gold “super atoms” can behave like the atoms in top-tier quantum systems—only far easier to scale. These tiny clusters can be customized at the molecular level, offering a powerful, tunable foundation for the next generation of quantum devices. Gold Clusters as Scalable Quantum Building Blocks Quantum computers, sensors, and other advanced [...]
WASHINGTON -- A single HPV vaccination appears just as effective as two doses at preventing the viral infection that causes cervical cancer, researchers reported Wednesday. HPV, or human papillomavirus, is very common and spread through sex. Most HPV infections clear up on their own but some linger, causing cancers that appear years later, including [...]
Scientists at the Swiss Light Source SLS have succeeded in mapping a piece of brain tissue in 3D at unprecedented resolution using X-rays, non-destructively. The breakthrough overcomes a long-standing technological barrier that had limited the use of X-rays for such studies. With the SLS upgrade now complete, the path lies open to imaging much [...]
Researchers found persistent microclot and NET structures in Long COVID blood that may explain long-lasting symptoms. Researchers examining Long COVID have identified a structural connection between circulating microclots and neutrophil extracellular traps (NETs). The discovery indicates that the two may interact in the body in ways that could lead to harmful effects when these [...]
Groups of normal cbiells can sense far into their surroundings, helping explain cancer cell migration. Understanding this ability could lead to new ways to limit tumor spread. The tale of the princess and the pea describes someone so sensitive that she can detect a single pea beneath layers of bedding. In the biological world, [...]
Bacteria that multiply on surfaces are a major headache in health care when they gain a foothold on, for example, implants or in catheters. Researchers at Chalmers University of Technology in Sweden have found a new weapon to fight these hotbeds of bacterial growth—one that does not rely on antibiotics or toxic metals. The [...]
