Hurricane Ian’s deadly impact on Florida seniors exposes need for new preparation strategies

All kinds of natural disasters — hurricanes, tornadoes, floods, wildfires, dangerous heat waves — pose substantial risks to older adults. Yet, not enough seniors prepare for these events in advance, and efforts to encourage them to do so have been largely unsuccessful.

Can monkeypox spread through contaminated food?

In a recent study published in the journal Microbial Risk Analysis, a team of researchers from France performed a qualitative risk assessment to determine the probability of transmission of monkeypox through the handling and consumption of food.

Faulty gene may explain why some people gain excessive weight despite normal food intake

A faulty gene, rather than a faulty diet, may explain why some people gain excessive weight even when they don't eat more than others, UT Southwestern researchers at the Center for the Genetics of Host Defense have discovered.

When monkeypox reaches rural communities, it collides with strained public health systems

When a case of monkeypox was reported in Nevada's Humboldt County in August, it was the state's first detected occurrence of the virus in a rural area. Soon, cases were found in other rural counties — Nye, Lyon, and Elko — posing another hurdle for public health systems that have been worn thin by the covid-19 pandemic.

Researchers fabricate a non-porous biodegradable vascular graft

Researchers developed a novel small-diameter biodegradable vascular graft that aids the formation of elastin-containing structures in the intima-media, which is important for the normal functioning of the artery.

Prescribed fire could play a role in reducing the abundance of ticks and pathogen transmission

Prescribed fire - a tool increasingly used by forest managers and landowners to combat invasive species, improve wildlife habitat and restore ecosystem health - also could play a role in reducing the abundance of ticks and the transmission of disease pathogens they carry, according to a team of scientists.

The Black Death may have influenced the evolution of genes involved in immune responses against pathogens

Researchers gathered empirical evidence that past pandemics due to infectious pathogens shaped the present-day susceptibility of humans to diseases, such as autoimmune diseases.

Why do some people attract mosquitoes more than others?

Mosquitoes (e.g., Aedes aegypti) are common vectors for many viruses that infect the human population, such as dengue, Zika, and yellow fever.

Gut-innervating nociceptors found to regulate the intestinal microbiota and promote tissue protection

According to a recent study, substance P produced by the nociceptors present in the gut lining confers protection against inflammation and tissue damage by increasing the number of beneficial microbes.

Metabolite discovery offers a potential way to address metabolic conditions

"Metabolism" describes the body's chemical changes that create the necessary materials for growth and overall health. Metabolites are the substances made and used during these metabolic processes - or, as a new discovery out of Scripps Research and its drug development arm, Calibr, indicates, they could also be potent molecules for treating severe diseases.

Extreme heat exposure linked with higher emergency room visits for kidney-related problems

Researchers linked meteorological history in New York State with data from over 1.1 million emergency room visits during 2005-2013 and found higher emergency room visits for kidney-related problems such as acute kidney injury, kidney stones, and urinary tract infections during days with extreme heat exposure.
