Waist size is a forgotten factor in defining obesity

A new study from the University of Iowa published in the Journal of the American Medical Association finds that some people considered to be a normal weight could unknowingly be at high risk for obesity-related health issues. Source: Waist size is a forgotten factor in defining obesity  

Low doses of radiation promote cancer-capable cells

Low doses of radiation equivalent to three CT scans, which are considered safe, give cancer-capable cells a competitive advantage over normal cells. Researchers studied the effects of low doses of radiation in mice and found it increases the number of cells with mutations in p53, a well-known genetic change associated with cancer. However, giving the…

Cognitive decline reversed 30 years in 6 weeks

Cognitive decline reversed 30 years in 6 weeks Cognitive decline reversed 30 years in 6 weeks After just 1 ½ months, participants increased their cognitive abilities to levels similar to those of middle-aged adults, 30 years younger. Control group members, who did not take classes, showed no change in their performance. “The participants in the…

For non-Hispanic whites in the US, life expectancy outlook worsens

For nearly a century, life expectancy in the United States has been increasing. By contrast, research from Irma Elo and Samuel Preston of the University of Pennsylvania shows that mortality numbers for non-Hispanic whites in the US are now rising, especially for women, 25- to 44-year-olds, and people living in rural areas. Source: For non-Hispanic…

Pet tags link widely used flame retardant to hyperthyroidism in cats

Feline hyperthyroidism is the most common endocrine-related disease of older cats, and its prevalence has skyrocketed since the first case was diagnosed in 1979. At the same time, new household flame retardants were introduced, and recently, scientists have suspected a link. Now, researchers reporting in ACS’ Environmental Science & Technology have associated hyperthyroidism with another…

How a popular antidepressant drug could rewire the brain

Prozac®, the trade name for the drug fluoxetine, was introduced to the US market for the treatment of depression in 1988. Thirty years later, scientists still don’t know exactly how the medication exerts its mood-lifting effects. Now, researchers report that, in addition to the drug’s known action on serotonin receptors, fluoxetine could rearrange nerve fibers…

Low VIT K may result in knee pain, disability or immobility

Low VIT K may result in knee pain, disability or immobility Low VIT K may result in knee pain, disability or immobility “older adults with low circulating vitamin K levels were nearly 1.5 times more likely to develop mobility limitation and nearly twice as likely to develop mobility disability compared to those with sufficient levels.…

Researchers teleport information within a diamond

Researchers from the Yokohama National University have teleported quantum information securely within the confines of a diamond. The study has big implications for quantum information technology — the future of how sensitive information is shared and stored. The researchers published their results on June 28, 2019 in Communications Physics. Source: Researchers teleport information within a…

Space station mold survives high doses of ionizing radiation

The International Space Station, like all human habitats in space, has a nagging mold problem. Astronauts on the ISS spend hours every week cleaning the inside of the station’s walls to prevent mold from becoming a health problem. New research being presented at the 2019 Astrobiology Science Conference, co-hosted by AGU and NASA June 24-28,…
