University of Ottawa-led team found a new viral entry for SARS-CoV-2 and suggests it may be able to use proteins to infect a wider range of cells. One of the many pressing research undertakings by the scientific community amid the ongoing COVID-19 pandemic has focused on ways the coronavirus manages to enter host cells. Now, in a study [...]
Marvel at the tiny nanoscale structures emerging from research labs at Duke University and Arizona State University, and it's easy to imagine you're browsing a catalog of the world's smallest pottery. A new paper reveals some of the teams' creations: itty-bitty vases, bowls, and hollow spheres, one hidden inside the other, like housewares for [...]
The COVID-19 epidemic has now entered its third year with its effects still being felt across the world. In many countries, there have been an alarming trend of waning vaccine efficacy paired with the emergence of variants with stronger immune escape and transmission ability. This consistent challenging of our pre-established immune barriers has driven [...]
As COVID-19 approaches its fourth year, Omicron continues to mutate and become more immune-evasive, health officials say. In December, the World Health Organization said variants descending from Omicron show more capacity to escape our immune system. "Omicron, the latest variant of concern, is the most transmissible variant we have seen so far, including all the sub-variants that [...]
Could the COVID-19 surge in China unleash a new coronavirus mutant on the world? Scientists don’t know but worry that might happen. It could be similar to omicron variants circulating there now. It could be a combination of strains. Or something entirely different, they say. “China has a population that is very large and [...]
Mount Sinai researchers have published one of the first studies to associate changes in blood gene expression during COVID-19 with “long COVID” in patients more than a year after they were hospitalized with severe COVID-19. Long COVID is the common name used for what is known more technically as post-acute sequelae of SARS-CoV-2 infection. The findings, published in [...]
The use of light to produce transient phases in quantum materials is fast becoming a novel way to engineer new properties in them, such as the generation of superconductivity or nanoscale topological defects. However, visualizing the growth of a new phase in a solid is not easy, due in-part to the wide range of [...]
Tracking the pathway to immunity, one cell at a time. Vaccines work their magic by effectively producing immune cells that survive for a long time, often for over decades. These immune cells build a barrier of protection that can prevent or minimize re-infection as well as a memory that enables us to identify [...]
You can easily rotate a baseball in your hand by twisting your fingers. But you need inventive scientists with access to world-class scientific facilities to rotate an object that is only two billionths of a meter wide. That is a million times smaller than a raindrop. Scientists at the U.S. Department of Energy’s (DOE) [...]
In new research published in Nature Communications, University of Sussex scientists demonstrate how a highly conductive paint coating that they have developed mimics the network spread of a virus through a process called 'explosive percolation' – a mathematical process which can also be applied to population growth, financial systems and computer networks, but which has not been seen [...]
