Words, Now Actions: Combating Racism in Healthcare

Many medical associations have publicly announced their determination to help eliminate racial disparities — from healthcare outcomes, from the level and quality of patient treatment, from their own memberships. How have those pronouncements translated into programs that could have, or even have had, positive impacts? For this article, Medscape Medical News asked several associations about tangible actions behind their vows […]

Assessing immunization capacity of vaccine platforms with DNA origami harboring SARS-CoV-2 receptor binding domain

In a recent study posted to the bioRxiv* preprint server, researchers demonstrated that vaccine frameworks containing deoxyribonucleic acid (DNA) origami possessing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain (RBD) induce strong protective immunity. Study: DNA Origami Presenting the Receptor Binding Domain of SARS-CoV-2 Elicit Robust Protective Immune Response. Image Credit: FUN FUN PHOTO/Shutterstock Background Vaccines that are both safe […]

What is the impact of SARS-CoV-2 Omicron BA.2 breakthrough infection on novel Omicron sublineages?

In a recent article posted to the bioRxiv* preprint server, investigators examined if severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.2 breakthrough infection in triple vaccinated individuals boosts Omicron BA.4/BA.5 and BA.2.12.1 cross-neutralization. Study: Omicron BA.2 breakthrough infection enhances cross-neutralization of BA.2.12.1 and BA.4/BA.5. Image Credit: Naeblys/Shutterstock Background The appearance of the SARS-CoV-2 Omicron variant of concern (VOC) during November […]

Monkeypox vaccine availability and effectiveness

A smallpox vaccine shown to protect against monkeypox has come under huge global demand, leading health authorities to warn against repeating the unequal distribution seen during the COVID pandemic. While monkeypox had long been endemic in parts of West and Central Africa, since May there have been outbreaks across the world. It has caused a scramble for doses of the […]

Bones Age by As Much As 10 Years After Long Periods in Space

Prolonged spaceflight can damage bone structure permanently and age parts of the skeleton prematurely by as much as 10 years, according to a new report. Adapted training programs and certain medications could better protect astronauts involved with future space missions, particularly ones that seek to travel longer distances and for longer periods of time than on the International Space Station […]

Minorities bore disproportionate mental health impact of pandemic

Racial and ethnic minorities bore a disproportionate mental health burden during the COVID-19 pandemic, according to a new study published this week in the open-access journal PLOS ONE by Andrew Chan of Harvard Medical School, Tim Spector of King’s College London, and colleagues. Previous research has established that minorities have borne a disproportionate COVID-19 burden, including higher rates of infection, […]

Study explores how active parent participation can improve neonatal health and reduce parental stress

The parent-offspring bond is a fundamental connection for humans. In neonatal care, particularly when caring for ill or preterm infants, special importance is given to active physical closeness between the parents and the infant. Research has shown that preterm infants who receive parental care in the form of physical and emotional closeness have better rates of growth and development. What’s […]

KAUST bioscientists develop new method to study the bone marrow microenvironment in greater detail

Deep molecular analysis of the bone marrow microenvironment reveals that the cells regulating blood stem cell maintenance are more diverse than expected and have features likely to be conserved between species. Tissues contain many different cell types, and it remains challenging to understand how they interact and contribute to tissue function. Now, state-of-the-art bioinformatics has enabled an international research team […]
