Scientists have developed a simple sonication method to create nanoplastics that closely mimic environmental particles, promising more realistic studies of their ecological impact. Plastics like polyethylene, PET, and polystyrene are used worldwide. Through wear and tear, recycling and chemical disintegration, they eventually break down in nature into tiny fragments. Less than 100 nanometers in [...]
A new Turkish study has raised concerns that Pfizer-BioNTech's COVID-19 vaccine may have subtle but serious side effects on the cornea. The research examined changes in the corneas of at least 64 patients before and after receiving both doses of the vaccine. According to the scientists involved in the study published in the journal [...]
As millions of people know firsthand, the most common side effect of mRNA vaccines like the COVID-19 shot is inflammation: soreness, redness and a day or two of malaise. But what if mRNA vaccines could be redesigned to sidestep that response altogether? In a new paper in Nature Biomedical Engineering, researchers at the University of [...]
An experimental mRNA vaccine boosted the tumor-fighting effects of immunotherapy in a mouse-model study, bringing researchers one step closer to their goal of developing a universal vaccine to "wake up" the immune system against cancer. Published today in Nature Biomedical Engineering, the University of Florida study showed that like a one-two punch, pairing the [...]
Elias Quijano, PhD; Diana Martinez-Saucedo, PhD; Zaira Ianniello, PhD; and Natasha Pinto-Medici, PhD, there are 25 other contributors, most from Yale's Department of Therapeutic Radiology and from the departments of genetics, molecular biophysics and biochemistry, biomedical engineering, pathology, and medical oncology and three from the University of Illinois Urbana-Champaign. Specifically, animal models of three [...]
New data from Denmark shows the HPV vaccine’s powerful long-term impact, while also revealing why cervical cancer screening is still essential. A Danish study published in the journal Eurosurveillance reports that women who received the human papillomavirus vaccine in their adolescence are significantly less likely to develop human papillomavirus infections later in life. Background Prolonged infection [...]
A research team at RCSI University of Medicine and Health Sciences has developed a 3-D printed implant to deliver electrical stimulation to injured areas of the spinal cord, offering a potential new route to repair nerve damage. Details of the 3-D printed implant and how it performs in lab experiments have been published in [...]
The Science Scientists have developed tiny nanocrystal particles made up of isotopes of the elements lanthanum, vanadium, and oxygen for use in treating cancer. These crystals are smaller than many microbes and can carry isotopes of elements such as actinium and radium. These isotopes undergo radioactive decay, emitting alpha particles (helium nuclei) that destroy cancer cells in [...]
A once-a-week shot from Australian scientists could spare people with Parkinson’s the grind of taking pills several times a day. The tiny, biodegradable gel sits under the skin and releases steady doses of two key medicines all week long, aiming for steadier symptom control, fewer side effects, and a much simpler routine. Early lab [...]
A new weekly injectable drug could transform the lives of more than eight million people living with Parkinson's disease, potentially replacing the need for multiple daily tablets. Scientists from the University of South Australia (UniSA) have developed a long-acting injectable formulation that delivers a steady dose of levodopa and carbidopa – two key medications [...]
