Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics. Researchers took a big step toward that future by developing a new tool that can design much more complex DNA robots and nanodevices than were ever possible [...]
Experts have discovered what they believe is the world’s most mutated COVID strain – and there’s one detail in particular that has scientists worried. Scientists have detected what is believed to be the world’s most mutated COVID strain as fears grow that new super variants may prolong the pandemic. The team of experts revealed [...]
SARS-CoV-2, the virus that causes COVID-19, likely does not directly infect the brain but can still inflict significant neurological damage, according to a new study from neuropathologists, neurologists, and neuroradiologists at Columbia University Vagelos College of Physicians and Surgeons. “There’s been considerable debate about whether this virus infects the brain, but we were unable [...]
ANSTO has contributed to a comprehensive investigation of a promising type of nanoparticle that could potentially be used for intractable brain cancers in a combined therapy. The study, which was led by Dr. Moeava Tehei and researchers from the University of Wollongong in combination with clinical partners, characterized and evaluated the properties of nanoparticles made [...]
The immune response needed to protect people against reinfection with the coronavirus will be explored in a new human challenge trial, researchers have revealed. Human challenge trials involve deliberately exposing healthy people to a disease-causing organism in a carefully controlled manner, and have proved valuable in understanding and tackling myriad conditions from malaria to [...]
Researchers from Duke University are developing a flu shot with the new technology that was used for two coronavirus vaccines. Both the Pfizer-BioNTech and the Moderna shots use part of the virus's genetic code called messenger RNA, or mRNA, to get the body to recognize the pathogen and attack if a person becomes infected. [...]
Researchers from the University of Liverpool have shown the potential of repurposing an existing and cheap drug into a long-acting injectable therapy that could be used to treat Covid-19. In a paper published in the journal Nanoscale, researchers from the University’s Centre of Excellence for Long-acting Therapeutics (CELT) demonstrate the nanoparticle formulation of niclosamide, a highly insoluble drug compound, [...]
Researchers have developed a new superbug-destroying coating that could be used on wound dressings and implants to prevent and treat potentially deadly bacterial and fungal infections. The material is one of the thinnest antimicrobial coatings developed to date and is effective against a broad range of drug-resistant bacteria and fungal cells, while leaving human [...]
The U.S. is recommending a "pause" in administration of the single-dose Johnson & Johnson COVID-19 vaccine to investigate reports of potentially dangerous blood clots. In a joint statement Tuesday, the Centers for Disease Control and Prevention and the Food and Drug Administration said they were investigating clots in six women that occurred 6 to [...]
The South African coronavirus variant is better at "breaking through" the defences of the Pfizer/BioNTech vaccine than other forms of the virus, Israeli experts said Sunday. However, one of the authors told AFP that while the study showed the variant to be relatively successful in infecting vaccinated people, it did not provide any data [...]
