Hamilton, ON (July 7, 2021) - A McMaster University team of researchers recently discovered how, exactly, the COVID-19 vaccines that use adenovirus vectors trigger a rare but sometimes fatal blood clotting reaction called vaccine-induced immune thrombotic thrombocytopenia or VITT.
The findings will put scientists on the path of finding a way to better diagnose and treat VITT, possibly prevent it and potentially make vaccines safer.
As society moves towards a renewable energy future, it's crucial that solar panels convert light into electricity as efficiently as possible. Some state-of-the-art solar cells are close to the theoretical maximum of efficiency--and physicists from the University of Utah and Helmholtz-Zentrum Berlin have figured out a way to make them even better.
Dr Bock, under the mentorship of Distinguished Professor Dietmar Hutmacher, from QUT Centre for Biomedical Technologies, has focused her research on bone metastases from breast and prostate cancers.
She developed 3D miniature bone-like tissue models in which 3D printed biomimetic scaffolds are seeded with patient-derived bone cells and tumour cells to be used as clinical and preclinical drug testing tools.
QUT PhD researcher Zachariah Schuurs said the research team had identified a new binding site on the SARS-CoV-2 spike protein.
"Binding of the CoV-2 spike protein to heparan sulphate (HS) on cell surfaces is generally the first step in a cascade of interactions the virus needs to initiate an infection and enter the cell.
"Most research has focused on understanding how HS interacts on the receptor-binding domain (RBD) and furin cleavage site of the SARS-CoV-2 virus's spike protein, as these typically bind different types of drugs, vaccines and antibodies.
A new study of lithium production in a classical nova found a production rate of only a couple of percent that seen in other examples. This shows that there is a large diversity within classical novae and implies that nova explosions alone cannot explain the amount of lithium seen in the current Universe. This is an important result for understanding both the explosion mechanism of classical novae and the overall chemical evolution of the Universe.
Cheap to produce and long to degrade, plastic was once a manufacturing miracle. Now, plastic is an environmental plague, clogging landfills and choking waterways. A Japan-based research team has turned back to nature to develop an approach to degrading the stubborn substance. Similar to how a protein binds to cellulose in plants or to chitin in crustaceans to initiate decomposition, an engineered protein is on its way to binding to plastic particles in an effort to more efficiently break them down.

Australian scientists researching how our immune system responds to COVID-19 have revealed that those infected by early variants in 2020 produced sustained antibodies, however, these antibodies are not as effective against contemporary variants of the virus.
The research is one of the world's most comprehensive studies of the immune response against COVID-19 infection. It suggests vaccination is more effective than the body's natural immune response following infection and shows the need to invest in new vaccine designs to keep pace with emerging COVID variants.
Polymer composite materials that combine magnetic and electrical properties are the subjects of particular attention for modern-day researchers. Their basic property is the ability to convert electric polarization into a magnetic field and vice versa. Although some materials exhibit a much better magnetoelectric effect, polymer-based composites are easier not only to produce but also to modify.
DANVILLE, Pa. - Having multiple chronic health conditions and living in a rural area were the top two factors affecting increased healthcare system contact among older patients with bladder cancer, a research team has found.
The Geisinger-led team evaluated 73,395 Medicare beneficiaries age 66 and older who had been diagnosed with non-muscle-invasive bladder cancer to assess their treatment burden, defined as the number of days the patients had contact with a health system in the year following diagnosis.
Researchers from IDIBELL and the University of Barcelona (UB) have described that neurons derived from Parkinson's patients show impairments in their transmission before neurodegeneration.
For this study, it has been used dopaminergic neurons differentiated from patient stem cells as a model.
By combining two distinct approaches into an integrated workflow, Singapore University of Technology and Design (SUTD) researchers have developed a novel automated process for designing and fabricating customised soft robots. Their method, published in Advanced Materials Technologies, can be applied to other kinds of soft robots--allowing their mechanical properties to be tailored in an accessible manner.
Despite having been formalized as a species in 1936, Wolbachia pipientis remains an elusive microbe. The reason why relates to the relationship it establishes with its hosts. Wolbachia lives inside the cells of 40% of the arthropods, in their majority insects, intertwined in a symbiosis so complex that it can no longer survive on its own. "Guessing what it takes to grow and manipulate it outside the host might not be possible", says Luís Teixeira, IGC principal investigator.
Many people instinctively associate mucus with something disgusting, but in fact, it has incredibly many valuable functions for our health. It keeps track of our important intestinal flora and feeds the bacteria. It covers all internal surfaces of our body, and, as a barrier to the outside world, it helps us protect ourselves from infectious diseases.
COLUMBUS, Ohio - Female vampire bats establish an egalitarian community within a roost rather than a society based on a clear hierarchy of dominance that is often seen in animal groups, a new study suggests.
Researchers observed more than 1,000 competitions for food among a colony of 33 adult female bats and juveniles living in captivity, assigning a rank to each bat based on a calculation of wins and losses in those contests.
