The Pfizer-BioNTech and Moderna mRNA vaccines have played a large role in preventing deaths and severe infections from COVID-19. But researchers are still in the process of developing alternative approaches to vaccines to improve their effectiveness, including how they’re administered. Immunologist and microbiologist Michael W. Russell of the University at Buffalo explains how nasal vaccines work, and where [...]
NASA is actively monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest Africa. This vast, developing phenomenon, called the South Atlantic Anomaly, has intrigued and concerned scientists for years, and perhaps none more so than NASA [...]
Infectious diseases such as COVID-19 can spread rapidly across the globe. Models that can predict how such diseases spread will strengthen national surveillance systems and improve public health decision-making. The COVID-19 pandemic has emphasized the significance of modeling in comprehending the spread of diseases and in providing crucial insights into disease prevention and control. A [...]
Results from a Scripps Research and UNC team pave the way for a vaccine and therapeutic antibodies that could be stockpiled to fight future coronavirus pandemics. A team of scientists from Scripps Research and the University of North Carolina (UNC) has found antibodies in the blood of certain COVID-19 donors that can block infection from a [...]
The human body is made up of thousands of tiny lymphatic vessels that ferry white blood cells and proteins around the body, like a superhighway of the immune system. It's remarkably efficient, but if damaged from injury or cancer treatment, the whole system starts to fail. The resulting fluid retention and swelling, called lymphedema, [...]
Suite of DNA nanotechnology devices engineered to overcome specific bottlenecks in the development of new therapies, diagnostics, and understanding of molecular structures. DNA nanostructures with their potential for cell and tissue permeability, biocompatibility, and high programmability at the nanoscale level are promising candidates as new types of drug delivery vehicles, highly specific diagnostic devices, [...]
Scientists from a collection of Chinese research institutions collaborated on a study of organ regeneration in mammals, finding deer antler blastema progenitor cells are a possible source of conserved regeneration cells in higher vertebrates. Published in the journal Science, the researchers suggest the findings have applications in clinical bone repair. With the activation of key [...]
Cancer is a complex and diverse disease, and its range of associated mutations is vast. The combination of these genomic changes in an individual is referred to as their “mutational landscape.” These landscapes vary based on the type of cancer, and even individuals with the same type of cancer can have very different mutation [...]
New research on inflammation could lead to better treatments to improve outcomes for people with advanced or previously untreatable cancers. Introducing bacteria to a tumour’s microenvironment creates a state of acute inflammation that triggers the immune system’s primary responder cells to attack rather than protect a tumour, according to researchers from UNSW Sydney and [...]
More efficient and longer lasting glucose-responsive insulin that eliminates the need for people with type 1 diabetes to measure their glucose levels could be a step closer thanks to a Monash University-led project. Published in the journal Advanced Materials, the preclinical study engineered a superior artificial pancreas system to release insulin precisely and smartly [...]
