Scientists discover a division of labor between genetic switches

Two X chromosomes are actually one too many. Female mammalian cells hence switch off one of them – but only when the cells start to specialize into tissues.

MRSA superbugs emerged on hedgehogs around 200 years ago

Scientists have found evidence that a type of the antibiotic resistant superbug MRSA arose in nature long before the use of antibiotics in humans and livestock, which has traditionally been blamed for its emergence.

Analyzing cell-free RNA could reliably predict preeclampsia

Imaging techniques such as ultrasound technologies and minimally invasive procedures are powerful tools for assessing pregnancy health and progression.

Horizontal gene transfer between viruses and hosts plays a major role in driving evolution

The first comprehensive analysis of viral horizontal gene transfer (HGT) illustrates the extent to which viruses pick up genes from their hosts to hone their infection process, while at the same time hosts also co-opt useful viral genes.

Scientists unravel how LPS prevents or promotes development of allergic disease

Immunologists have long been baffled by LPS, the bacterial lipopolysaccharide that helps form the cell walls of Gram-negative bacteria.

First-responder cells launching the repair after heart attack promote inflammation overdrive

First-responder cells launching the repair after a heart attack are so frantic about fixing the damage that they promote more inflammation than necessary, new research in mice suggests.

Study defines a novel way to identify potential new interventions for autism

Researchers from King's College London have shown that there are variations in how a brain chemical called GABA regulates the processing of visual stimuli.

Study uncovers a harmful neutrophil behavior linked to cardiovascular disease

Scientists led by Dr. Andrés Hidalgo at the Centro Nacional de Investigadores Cardiovasculares have discovered that circulating neutrophils - a type of immune cell - acquire different behavior patterns during inflammatory processes.

NRL researchers aim to advance understanding of how cells organize and communicate

U.S. Naval Research Laboratory researchers in the Chemistry Division apply their knowledge of biology in conjunction with materials to improve understanding of how cells and tissues organize and apply new methods to affect cell communication.

Researchers develop new tool to predict pre-eclampsia

A study of pregnant women's blood RNA has found specific molecular profiles that identify women at risk of pre-eclampsia. These insights can identify complications before a woman experiences symptoms.

Exploring SARS-CoV-2-like viruses to mitigate the risk of zoonotic transmission to humans

In a new study, a team of researchers developed a genetic assay to evaluate several clade 2 and clade 3 receptor-binding domains (RBD) of spike (S) protein sequences of genus sarbecovirus.

Erectile dysfunction medication found to intensify abdominal aortic aneurysms in mice

In a laboratory study in mice, sildenafil, a commonly used erectile dysfunction medication, was found to worsen abdominal aortic aneurysms, indicating additional research may be needed to determine if the medication may have the same effect on people, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Researchers compare survival rates of AML patients treated with two forms of transplantation methods

Acute myeloid leukemia (AML) is a common type of blood cancer that has a relatively low survival rate. It is particularly deadly for patients suffering from refractory and relapsed AML (R/R AML), meaning their cancer has stopped responding to treatment and has returned after a period of remission.

Can the COVID-19 delta variant evade vaccine-induced immunity?

Can the COVID-19 delta variant evade vaccine-induced immunity? We spoke to Professor Brian J. Willett from the University of Glasgow to find out.

New gene therapy addresses primary cellular deficit associated with limb-girdle muscular dystrophy 2B

Children's National Hospital experts developed a new pre-clinical gene therapy for a rare disorder, known as limb-girdle muscular dystrophy (LGMD) 2B, that addresses the primary cellular deficit associated with this disease.

Research provides compelling insights into the complex nature of genomic imprinting in mice

Mammalian offspring inherit two versions, or alleles, of each gene with one allele from each biological parent. However, gene expression is tightly regulated and certain genes undergo the phenomenon of "genomic imprinting", which is where only the allele received by the male or the female parent is expressed.

Experts cautiously optimistic about risks of Delta-Omicron mutations mix

Researchers evaluate the risk of the P681R, N501Y, and D614G mutations of current interest co-occurring naturally due to convergent evolution.

New Potocsnak Longevity Institute aims to extend human 'healthspan'

In the not-too-distant future, you'll be able to check into the Human Longevity Laboratory to find out how old you really are, physiologically speaking.

The impact of natural selection on sequence diversity in SARS-CoV-2

Recent genomic analysis demonstrates that the SARS-CoV-2 genome is under two distinct selective forces.

Study finds critical metabolic vulnerability of diffuse large B cell lymphomas

Aggressive and relatively common lymphomas called diffuse large B cell lymphomas (DLBCLs) have a critical metabolic vulnerability that can be exploited to trick these cancers into starving themselves, according to a study from researchers at Weill Cornell Medicine and Cornell's Ithaca campus.
