Daily circadian cycles may impact our ability to fight disease

An analysis of an exhaustive dataset on cells essential to the mammalian immune system shows that our ability to fight disease may rely more heavily on daily circadian cycles than previously assumed.

Inherited or transmitted gut microbes affect skeletal development in animals

Gut microbes passed from female mice to their offspring, or shared between mice that live together, may influence the animals' bone mass, says a new study published today in eLife.

Study examines the role of gut microbes in anorexia

You are likely familiar with the serious consequences of anorexia for those who experience it, but you might not be aware that the disorder may not be purely psychological.

Researchers determine the atomic structure of protein that helps coronavirus to evade immune cells

A team of HIV researchers, cellular biologists, and biophysicists who banded together to support COVID-19 science determined the atomic structure of a coronavirus protein thought to help the pathogen evade and dampen response from human immune cells.

Study shows COVID-19 pneumonia is different from typical pneumonia

Bacteria or viruses like influenza that cause pneumonia can spread across large regions of the lung over the course of hours. In the modern intensive care unit, these bacteria or viruses are usually controlled either by antibiotics or by the body's immune system within the first few days of the illness.

Seed-borne bacterium can lead to complete resistance to a particular pathogen

Rice is the staple food of about half the world's population. The cultivation of the rice plant is very water-intensive and, according to the German aid organization Welthungerhilfe, around 15 per cent of rice is grown in areas with a high risk of drought.

Researchers identify bacterium that produces pharmaceutical all-purpose weapon

For some years, an active substance from the leaves of an ornamental plant has been regarded as a possible forerunner of a new group of potent drugs. So far, however, it has been very laborious to manufacture it in large quantities.

Trinity researchers discover key mechanism underlying bacterial skin colonization in atopic dermatitis

Researchers from Trinity College Dublin have discovered a key mechanism underlying bacterial skin colonization in atopic dermatitis, which affects millions around the globe.

Vimentin could be a major co-factor that aids SARS-CoV-2 infection

A recent study has found that extracellular vimentin can bind to SARS-CoV-2 spike protein in vitro, and antibodies against vimentin can decrease virus infectivity by up to 80%. This suggests vimentin could aid the virus’s binding to host cells and help in infection.

Research provides better understanding of how antibiotic resistance arises

Researchers at the Quadram Institute on the Norwich Research Park have shown how the development of antibiotic resistance by bacteria can have 'side-effects' for them including affecting their ability to cause disease.

Biomarkers can predict how genetically identical cells behave differently under stress

A set of biomarkers not traditionally associated with cell fate can accurately predict how genetically identical cells behave differently under stress, according to a UT Southwestern study.

MSU researchers show how microbes could soak up toxic pollutants

When Michigan State University's Gemma Reguera first proposed her new research project to the National Science Foundation, one grant reviewer responded that the idea was not "environmentally relevant."

Surface-textured nanocrystals for biofilm eradication

The COVID-19 pandemic is raising fears of new pathogens such as new viruses or drug-resistant bacteria.

Study shows how new antibiotic resistance genes arise from random DNA sequences

An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, Swedish and American researchers have shown how new genes that produce resistance can arise from completely random DNA sequences. The results have been published in the journal PLOS Genetics.

Researchers demonstrate lab tool that simplifies simulations of the human intestine

Rice University and Baylor College of Medicine researchers have found a way to mimic conditions in intestines, giving them a mechanical model for the real-time growth of bacterial infections.

Gut and oral microbiomes predict COVID-19 severity

One question that continues to remain unanswered during the ongoing coronavirus disease 2019 (COVID-19) pandemic has been why is there a distinctive hit-and-miss pattern when it comes to severe disease? An interesting new study that appears on the medRxiv* preprint server pinpoints one highly relevant risk factor: the state of the oral and gut microbiomes.

Researchers call for policies and laws mandating the use of surgical smoke evacuations systems

If you've ever been in an operating room where tools are used to simultaneously cut and cauterize human flesh, you know what surgical smoke is.

Researchers develop new sequencing-based approach for pathogen discovery

A sequencing-based solution can be utilized to determine infection clearance and microbiota recovery. Next, the researchers will apply the technique to investigate the coronavirus disease.

Researchers trace back the evolutionary history of antibiotic resistance genes

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes.

Researchers use nanotechnology to develop new coronavirus mask model

A US-based research team designed and fabricated electrospun nanofibrous air filters that hold promise for applications in personal protective equipment and indoor environments. The team compared the filtration efficiency of coronavirus and NaCl aerosols to a broad spectrum of electrospun air filters and face masks.
