First study of its kind to investigate a high priority but little known pathogen found in Irish hospitals

By understanding the epidemiology and population biology of a significant and high-priority pathogen, Enteroccocus faecium (E. faecium) in Irish hospitals, researchers are providing the evidence base for more effective surveillance, and infection and prevention control strategies aimed at minimizing the spread of the antibiotic resistant bacteria.

Role of disordered protein interactions in gene expression

New findings on bacteria that increase risk of pancreatic cancer

Bacteria from the digestive system seem to have the potential to cause damage to pancreatic cells, increasing the risk of malignant tumors. Now for the first time, live bacteria from cystic pancreatic lesions that are precursors to pancreatic cancer, have been analyzed by researchers. The study can lead to prophylactic interventions using local antibiotics.

Researchers find new link between a disrupted body clock and inflammatory diseases

Ubiquitous food additive alters human microbiota and intestinal environment

New clinical research indicates that a widely used food additive, carboxymethylcellulose, alters the intestinal environment of healthy persons, perturbing levels of beneficial bacteria and nutrients. These findings demonstrate the need for further study of the long-term impacts of this food additive on health.

Reduced meat diet has many advantages

Which diet is better: moderately reduce meat consumption and eat more fruit, vegetables and wholegrain products or eating more fish and seafood? Or even switch completely to a vegan diet? A new study shows that the answer to these questions is not as clear-cut as one might think -- depending on which impacts one closely looks.

Biomedical engineers find neural activity during rest is highly organized

When mice rest, individual neurons fire in seconds-long, coordinated cascades, triggering activity across the brain, according to new research. Previously, this was thought to be a relatively random process -- single neurons firing spontaneously at random times without external stimulation.

Those that game together, stay together

Play is important for the development of complex social, emotional, physical, and cognitive skills. Play provides young individuals with a safe space to practice new behaviors without grave repercussions. While most animals engage in play, only humans engage in rule-based games. Which kinds of games people play -- competitive or cooperative -- may depend on their cultural background. In a new study, researchers screened historical data to answer the question whether cultures play games that correspond to how cooperative they are.

New method gives rapid, objective insight into how cells are changed by disease

A new 'image analysis pipeline' is giving scientists rapid new insight into how disease or injury have changed the body, down to the individual cell. It's called TDAExplore, which takes the detailed imaging provided by microscopy, pairs it with a hot area of mathematics called topology, which provides insight on how things are arranged, and the analytical power of artificial intelligence to give, for example, a new perspective on changes in a cell resulting from ALS and where in the cell they happen, according to a cell biologist involved with the study.

Reboot and recall: New brain hub for memory restoration identified

Researchers now show that stimulation of the anterior thalamus increases memory-related brain activity and restores memory function in rats with mammillothalamic tract (MTT) lesions. Their findings suggest that therapies involving targeted stimulation of the anterior thalamus could help with memory restoration in patients with brain injury.

Virtual reality tool to be used in the fight against disease

Science has the technology to measure the activity of every gene within a single individual cell, and just one experiment can generate thousands of cells worth of data. Researchers have now revolutionized the way this data is analyzed -- by using 3D video gaming technology.
