Adverse pregnancy outcomes in women with inactive inflammatory bowel disease

A study by the University of Gothenburg found that women with inactive inflammatory bowel disease (IBD) have a higher risk of giving birth prematurely, particularly if they have microscopic inflammation in their intestinal mucosa. This association was not seen for other adverse pregnancy outcomes, such as growth restriction.

Von Fricken receives funding for study aimed at determining threat of detection-resistant malaria & arboviruses in Haiti

Michael E. von Fricken, an Associate Professor at George Mason University, has received $78,999 from the U.S. Department of the Navy for a project to determine the threat of detection-resistant malaria and arboviruses in Haiti. The study aims to develop sampling approaches, analyze findings, and generate reports documenting progress.

Willingness to use video telehealth increased during pandemic

The study found that the willingness to use video telehealth increased overall from 51% in February 2019 to 62% in March 2021. Subgroups with the lowest levels of willingness, such as Black adults and adults with less than a high school education, saw significant increases in their willingness to use video telehealth.

Our brains “time-stamp” sounds to process the words we hear

A new study by NYU researchers reveals that our brains use a 'time-stamp' mechanism to process the order of incoming sounds, allowing us to correctly recognize words being said. The brain achieves this feat by correlating different neural populations with specific speech sounds and time-stamping each sound with its relative order.

Fearful cats also express other problematic behaviour – Socialisation important already at early stages of life

A study found that fearful cats tend to display excessive grooming and aggression towards humans. Early socialization with humans is crucial in reducing fearfulness and related behavioral issues in cats. The research also discovered a correlation between litterbox issues and aggressive behavior in households with multiple cats.

Starved yeast poisons clones

Researchers at the University of Tokyo discovered that yeast releases toxins to kill its own clones and surrounding microorganisms when starved of glucose, a phenomenon called latecomer killing. This behavior helps yeast survive mass starvation and aids in the selection of toxin-producing offspring.

UCalgary study points to potential new treatment for inflammatory bowel diseases

Researchers at UCalgary have discovered a potential new treatment for fibrosis, a condition that causes thickening of the gut wall and life-threatening blockage in people with Crohn's disease and ulcerative colitis. The study suggests that drugs targeting specific sensors may prevent inflammation-associated gut blockage.

Hazardous flame retardant OPEs detected at higher levels than BFRs at an informal end-of-life vehicle recycling site

Researchers found emerging organophosphate esters (OPEs) at higher concentrations than legacy brominated flame retardants (BFRs) in settled dust from informal end-of-life vehicle recycling sites in Vietnam. Chlorinated OPEs were specifically identified as a major contaminant, possibly released from vehicle upholstery and fabrics.

Are covid ‘comas’ signs of a protective hibernation state?

Researchers at MIT's Picower Institute suggest that Covid-19 patients in comas may enter a protective hibernation state to shield cells from oxygen scarcity. This hypothesis is supported by observations of cardiac arrest patients treated with hypothermia and the painted turtle, which also enters a similar state during prolonged anoxia.

Study: How piracy can unravel company profits in product bundling

A new study by University of Texas at Dallas researchers found that bundling zero-marginal-cost products can lead to increased piracy and loss of profits. In the presence of piracy, mixed bundling is not necessarily a better strategy, and manufacturers should reassess the efficacy of bundling in markets where piracy is a concern.
