Severity of menopause symptoms linked to a woman's cognitive performance

Menopause is often accompanied by an array of symptoms that can detract from a woman's quality of life. A new study suggests that the severity of some of those symptoms - especially depression and sexual dysfunction - were linked to a woman's cognitive performance.

New method for monitoring circulating SARS-CoV-2 variants and detecting new ones

To understand and act early and appropriately to emerging variants of concern, researchers have explored the possibility of having a variant-agnostic detection assay.

A common cold may boost the immune system against COVID-19

A recent groundbreaking research paper published in the journal Nature Communications reveals the association of circulating SARS-CoV-2-specific T cells at exposure with lack of infection – implying the protective role for cross-reactive immune T cells in coronavirus disease 2019 (COVID-19) and opening the door for second-generation vaccines that could circumvent spike-antibody immune escape variants.

Decoding imagined language to treat people suffering from aphasia

What if it were possible to decode the internal language of individuals deprived of the ability to express themselves? This is the objective of a team of neuroscientists from the University of Geneva (UNIGE) and the University Hospitals of Geneva.

Study finds T cell response mostly conserved against SARS-CoV-2 Omicron variant following infection or vaccination

A new preprint examines the extent of protection offered by T cell responses to primary vaccination and/or natural infection with the virus.

Higher olive oil consumption linked with lower risk of cardiovascular disease, cancer mortality

Consuming more than 7 grams (>1/2 tablespoon) of olive oil per day is associated with lower risk of cardiovascular disease mortality, cancer mortality, neurodegenerative disease mortality and respiratory disease mortality, according to a study publishing today in the Journal of the American College of Cardiology.

Mapping regulatory T-cell populations in COVID-19 patients

In a new study, researchers used mass spectrometry to investigate changes to immune systems, in particular regulatory T-cells (Tregs), in a large cohort of moderate, severe, and critical Japanese coronavirus disease 2019 (COVID-19) patients and healthy controls.

SARS-CoV-2 viral mutations shown to have a limited effect on T cell immunity

New research suggests that viral mutations have a minimal effect on T cell immunity, which could explain the protection provided by vaccination against severe COVID-19, despite the significant loss of neutralizing antibodies.

Study reveals how the brain’s blue spot shapes selective attention

How can we shift from a state of inattentiveness to one of highest attention? The locus coeruleus, literally the "blue spot," is a tiny cluster of cells at the base of the brain.

Researchers isolate Omicron variant, leveling the path to vaccine development and vaccine efficacy studies

Researchers from India have now successfully grown and isolated the Omicron variant from hamsters in vivo with further culturing in the Vero CCL-81 cells in vitro, in a step forward towards testing the effectiveness of existing SARS-CoV-2 vaccines and generation of new Omicron appropriate vaccines.

New method to estimate how individual mutations affect transmission of SARS-CoV-2

A new study, posted to the medRxiv* preprint server, constructs an analytical SIR-based epidemiological model to analyze the effects of mutations on SARS-CoV-2 transmission from genomic surveillance data.

AIBS scientists shed light on discrepancies in grant review participation

While numerous studies have described the funding discrepancies faced by scientists at minority-serving institutions (MSIs), there is a relative paucity of information available about MSI-based scientists' participation in grant review, the process used by research funders to allocate their budgets.
