Probiotics improve nausea and vomiting in pregnancy, according to new study

In a first-of-its-kind study, researchers at the UC Davis School of Medicine found that probiotics significantly improve the symptoms of pregnancy-related nausea, vomiting and constipation. The findings were published in the journal Nutrients. [...]

A chewing gum that could reduce SARS-CoV-2 transmission

A chewing gum laced with a plant-grown protein serves as a "trap" for the SARS-CoV-2 virus, reducing viral load in saliva and potentially tamping down transmission, according to a new study. [...]

Belgian zoo hippos test positive for Covid

Two hippos in a Belgian zoo have tested positive for COVID-19, their keepers announced Friday, stressing that the giant animals do not appear to be in danger. [...]

Covid booster urged for people 18 and over in Canada

A Canadian government immunization advisory committee on Friday urged Covid-19 booster shots for people 18 and older who are at greater risk of infection, while also strongly recommending those 50 years-plus to get the third jab. [...]

Omicron 'ultimate evidence' of danger from vaccine inequity: Red Cross

The emergence of the Omicron variant of the coronavirus is the "ultimate evidence" of the danger of unequal vaccination rates around the world, the head of the Red Cross said on Friday. [...]

Researchers find surprising benefit to the immune system following infection

The human body's immune system weakens over time, making older adults more susceptible to infections and leaving scientists with the puzzling dilemma of how to maintain health across the lifespan. As part of continuing research at the University of Arizona Health Sciences, a recent study into how infection affects the immune system resulted in a surprising outcome that could lead to new immunotherapies to prevent disease and novel ways to strengthen the aging immune system. [...]

Treadmill exercise training shows promise for managing cognitive effects of multiple sclerosis

A pilot study by a team of multiple sclerosis (MS) researchers showed that treadmill walking exercise training may be an effective approach to managing the debilitating cognitive effects of the disease. Their article, titled, "Effects of walking exercise training on learning and memory and hippocampal neuroimaging outcomes in MS: A targeted, piloted randomized controlled trial," was published in Contemporary Clinical Trials . [...]

Scientists explain why neurons consume so much fuel even when at rest

Pound for pound, the brain consumes vastly more energy than other organs, and, puzzlingly, it remains a fuel-guzzler even when its neurons are not firing signals called neurotransmitters to each other. Now researchers at Weill Cornell Medicine have found that the process of packaging neurotransmitters may be responsible for this energy drain. [...]

Rapid test identifies antibody effectiveness against COVID-19 variants

Biomedical engineers at Duke University have devised a test to quickly and easily assess how well a person's neutralizing antibodies fight infection from multiple variants of COVID-19 such as Delta and the newly discovered Omicron variant. [...]

Immune system-stimulating nanoparticle could lead to more powerful vaccines

A common strategy to make vaccines more powerful is to deliver them along with an adjuvant—a compound that stimulates the immune system to produce a stronger response. [...]
