Developing cost-effective and milder synthetic routes to create oxygen heterocycles

Every biological reaction is a chemical reaction. The exchange of carbon dioxide for oxygen in our lungs and blood cells, for example, is caused by molecules releasing chemicals and reforming with new ones.

Human heart evolved to adapt to the demands of life, study says

The human heart underwent major physical changes throughout history, based on what activities or lifestyle people had, a new study found. As a result, human hearts are better suited to endure various types of activities.

Low blood iron levels increase risk of Dengue

The more anemic you are, the more likely it is that you could spread dengue fever because mosquitoes feeding on your blood have a greater chance of picking up the virus. This was reported by a new study published in the journal Nature Microbiology on September 16, 2019.

ACA and chiropractors encourage people to take steps for better musculoskeletal health

The American Chiropractic Association and chiropractors nationwide are encouraging the public to take steps to better musculoskeletal health during National Chiropractic Health Month this October.

Mutated ciliary genes tied to heart valve birth defect

The heart pumps blood throughout the body to provide the needed oxygen and nutrients. In the heart, blood flows to get oxygen from the lungs to deliver to the cells. Some of the most important structures in the heart are the valves, because they prevent the backflow of blood, avoiding the mixture of oxygenated blood with the ones that still need to be oxygenated.

Dengue fever is endemic in places where iron deficiency is more common

Mosquitoes are more likely to acquire the dengue virus when they feed on blood with low levels of iron, researchers report in the 16 September issue of Nature Microbiology.

New effort to study gastrointestinal gases and their influence on gut disorders

A source of embarrassment to some, or pure comedy to others, flatulence and the gases of the intestines are increasingly seen as playing an important role in our digestive health.

Virginia Tech scientist receives American Heart Association award to study stroke recovery

When someone has an ischemic stroke, doctors work swiftly to remove the arterial blockage and restore blood flow to the brain. But sometimes even once the blockage is removed, there's lasting - sometimes fatal - damage.

California hospitals and nursing homes brace for wildfire blackouts

California has seen a relatively slow start to this year's wildfire season, but Wanda Chaney still frets every time it's hot and windy in Chico, a college town about two hours north of Sacramento. She's far less worried about an actual wildfire than the power company shutting off her electricity to prevent one.

Supercooling helps preserve human transplant organs longer

Now a new supercooling technique for human organs promises to extend the period from the moment of removal to 1.5 days rather than just a few hours. This provides a useful window of time within which transplant teams and patients can hope to get a viable organ.
