New biomarker could help identify people at risk of Alzheimer's disease

Early diagnosis of Alzheimer's disease has been shown to reduce cost and improve patient outcomes, but current diagnostic approaches can be invasive and costly.

Researchers discover specific blood biomarker that predicts kidney transplant rejection

Researchers at the University of Pittsburgh School of Medicine have discovered a blood biomarker that predicts kidney transplant rejection with a lead time of about eight months, which could give doctors an opportunity to intervene and prevent permanent damage.

Novel single-particle digital assay using plasmonic nanobubbles

An interdisciplinary team from the University of Texas applied DIAMOND to the respiratory syncytial virus (RSV) diagnostics and demonstrated that DIAMOND is 150 times more sensitive than commercial lateral flow assays. They found that the measurements are completed within 2 minutes. The results of this study are published on the medRxiv* preprint server.

Study reveals key mechanism by which exercise promotes immunity, strengthens bones

Scientists at the Children's Medical Center Research Institute at UT Southwestern (CRI) have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced.

New study sheds light on specialized compartments exhibited by Earth's single-celled ancestors

Scientists have long speculated about the features that our long-ago single-celled ancestors might have had, and the order in which those features came about. Bubble-like compartments are a hallmark of the superkingdom to which we, and many other species including yeast, belong.

Travel bans are effective only in the first phases of pandemic

Travel bans have been key to efforts by many countries to control the spread of COVID-19. But new research aimed at providing a decision support system to Italian policy makers, recently published in the Journal of the Royal Society Interface, suggests that reducing individual activity (i.e., social distancing, closure of non-essential business, etc.) is far superior in controlling the dissemination of Sars-CoV-2, the virus that causes COVID-19.

Microchip can help scientists study the regenerative potential of mice heart cells

Baby mice might be small, but they're tough, too. For their first seven days of life, they have the special ability to regenerate damaged heart tissue.

Combination technique can toggle specific genes on and off

The genetic tool CRISPR has been likened to molecular scissors for its ability to snip out and replace genetic code within DNA.

New approach can reduce unnecessary evaluations of swollen lymph nodes after COVID-19 vaccination

Swelling of lymph nodes in the armpit area is a normal response to COVID-19 vaccinations, but when they are seen on mammograms, they can be mistaken for nodes that are swollen because of cancer. In some cases, the nodes are biopsied to confirm they are not cancer.

Artificial control of the glial state could help improve memory function

Tohoku University scientists have shown that neuronal and glial circuits form a loosely coupled super-network within the brain.

High expression of ACE2 receptors in developing ovaries increases SARS-CoV-2 risk

A team of scientists from China collaborated to find if SARS-CoV-2 could also infect the ovary at different developmental stages.

Study: Battery storage can help protect medically vulnerable households

Extreme weather driven by climate change is making power outages more commonplace even as the need for electricity-dependent home health equipment grows.

Strategy based on alternating lockdowns can help defeat COVID-19

Social distancing - from mobility restrictions to complete lockdowns -- can take many weeks, possibly even months, a potentially devastating outcome for social and economic stability.

Is the CDC 10-day COVID-19 quarantine guideline enough?

Researchers at the University of Florida and the Florida Department of Health evaluated test positivity rates for SARS-CoV-2 infection among student contacts. The team found that nine days are not enough to ascertain that the student did not contract the virus.

SARS-CoV-2 transmission bottleneck is of the order of one to three virions

Now, a new study, posted to the bioRxiv preprint server by the same researchers, focussing on the Austrian region, found that SARS-CoV-2 transmission bottlenecks to be much tighter than previously thought.

Lab study of South African SARS-CoV-2 variant and Moderna vaccine: reduced neutralization, but still protective

Researchers from the US recently compared antibody binding and viral neutralization against 2 SARS-CoV-2 variants that emerged in different parts of the world. The researchers used sera from spike mRNA vaccinated and naturally infected individuals against a circulating B.1 variant and the emerging B.1.351 variant. The study is published on the preprint server bioRxiv.

Full characterization of mammalian-produced SARS-CoV-2 receptor binding domains

A research paper recently uploaded to the preprint server bioRxiv by Dominguez-Vega et al. (23rd Feb, 2021) describes an in-depth structural analysis of the RBD of the spike protein expressed in mammalian Chinese hamster ovary (CHO) cells and human embryonic kidney (HEK293) cells, providing a new understanding of protein structure and function.

Mapping the dominance of the SARS-CoV-2 UK variant in Europe

A research paper recently uploaded to the preprint server medRxiv* by Vespignani et al. (February 22nd, 2021) uses mathematical models to map the spread of this lineage across Europe, establishing that a 50% increase to the transmissibility of the variant would allow it to become dominant in major metropolitan areas by the end of March 2021.

Complement system appears to be specifically implicated in severe COVID-19

Researchers in the United States have conducted a study showing that activation of the complement system is specifically implicated in the pathogenesis of severe coronavirus disease 2019 (COVID-19), rather than being a broader indicator of critical illness.

Study investigates characteristics of high utilizers for psychiatric hospital services

Dropping out of high school, having schizophrenia, or being diagnosed with a co-occurring personality disorder increases the likelihood of someone becoming a "high utilizer" of inpatient psychiatric hospital services, according to a new study by researchers at The University of Texas Health Science Center at Houston .
