Preparing for the next pandemic: Harmonize vaccinations in Canada

To prepare for the next pandemic and provide a coordinated approach to vaccination across the country, Canada should create Canadian Immunization Services based on the Canadian Blood Services model, authors propose in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.210670.

Preparing T cells for the long haul

In a new Nature Immunology study, researchers at La Jolla Institute for Immunology (LJI) report that T cells can be engineered to clear tumors without succumbing to T cell exhaustion.

Program seeks to reduce preventable cancers with free screening, same-day results

George Mason University's Dr. Michelle Williams shares program evaluation results determining the feasibility of offering free, same-day cancer screening and health education to reduce disparities. The program examined how access to free screenings affects participants' knowledge about cancer, self-efficacy for obtaining healthcare, and intentions to change health behaviors. The program had a...

Researchers: HtrA1 augmentation is potential therapy for age-related macular degeneration

Research conducted at the Sharon Eccles Steele Center for Translational Medicine (SCTM) at the University of Utah's John A. Moran Eye Center explains why people carrying a block of genetic variants strongly associated with the development of age-related macular degeneration (AMD) may develop the disease and identifies a potential therapeutic pathway for slowing or even reversing disease...

RNA modification may protect against liver disease

An RNA modification may offer protection against non-alcoholic fatty liver, a condition that results from a build-up of fat in the liver and can lead to advanced liver disease, according to a new study by UCLA researchers. The modification may also explain why females tend to have higher fat content in the liver.

SARS-CoV-2 spike mutation L452R evades human immune response and enhances infectivity

An international team of researchers led by Kumamoto and Tokyo Universities (Japan) have shown that the L452R mutation of the SARS-CoV-2 spike protein, which is common to two variants (Epsilon and Delta), is involved in cellular immunity evasion via the human leukocyte antigen (HLA) A24, and enhances viral infectivity. HLA-A24 is one of the most prominent HLA-class I alleles, especially in...

Scientists adopt deep learning for multi-object tracking

Implementing algorithms that can simultaneously track multiple objects is essential to unlock many applications, from autonomous driving to advanced public surveillance. However, it is difficult for computers to discriminate between detected objects based on their appearance. Now, researchers at the Gwangju Institute of Science and Technology (GIST) adapted deep learning techniques in a...

Scientists on the scent of flavor enhancement

With hopes to capitalize on the smell factor in flavor development, researchers are exploring how the route an aroma takes to get to the olfactory system, through the nose or the back of the throat, influences our response to the scent in question.
