People who suffer from migraines often have trouble getting a good night's sleep, but it's not clear whether migraines cause poor sleep quality or poor sleep quality causes migraines.
A new meta-analysis of 32 studies involving more than 10,000 people doesn't answer the question but it did identify two key factors. First, adults and children ...Read more
Apart from biological factors such as amyloid plaques and tau tangles, new research suggests some personality traits may be risk factors for Alzheimer's disease. The factors have been proven to be causal but may be associated with Alzheimer's and related dementias.
Specifically, scientists found that neuroticism -- the personality trait that ...Read more
When people watch the same movie together, their hearts begin to beat in time. It's not the shared emotional experience however that causes the effect but rather similar cognitive work in their brains.
In a new study, researchers tested volunteers listening to an audiobook of Jules Verne's "20,000 Leagues Under the Sea," watching ...Read more
When jobs began disappearing during the COVID-19 pandemic, it was presumed health insurance coverage would soon follow. But a new analysis indicates the percentage of uninsured working-age adults remained the same from March 2019 to April 2021 at approximately 11%.
There was internal change, however. Many people moved from employer plans to ...Read more
Children are increasingly getting the majority of their daily calories from ultraprocessed foods high in sugar, salt and trans fat, says a new report. In 2000, data on daily food intake estimated ultraprocessed foods constituted 61% of children's caloric consumption. In 2018, the latest data available, it had risen to 67%.
The rise in ...Read more
Even as medical science expands its abilities to regrow cells to restore lost functions, hearing loss remains a stubborn, unsolved challenge. Researchers now may know why. The inner ear's hair cells, which pick up sound vibrations, don't regenerate after being damaged, which is why hearing loss is irreversible.
Scientists have discovered that...Read more
Our daily energy expenditure, otherwise known as our metabolism, changes over the course of our lives. A slower metabolism is often credited (blamed) for why we put on weight in later life, especially women.
As it turns out, while metabolism does change over time, it doesn't necessarily do it in the way we thought. New research shows distinct...Read more
Adding to a small but growing body of research, an English study found that the vast majority of children recover from COVID-19 within two months after testing positive. However, the number with persistent symptoms wasn't zero. Of roughly 1,700 pediatric patients surveyed, roughly 4% of children still felt symptoms after one month after ...Read more
With vaccination rates slowing (or never really getting momentum) in some parts of the country, U.S. public health officials have begun to worry about unused COVID-19 vaccines going to waste as their expiration dates come up this summer. Authorities estimate there are enough doses at risk to vaccinate more than 13 million people.
A Pox On ...Read more
COVID-19 hits some people harder than others, with more severe or longer-lasting symptoms and consequences. Gene hunters are beginning to turn up clues as to why by probing dozens of parts of the human genome for evidence that some genes confer greater susceptibility to SARS-CoV-2 infection or severe illness.
Findings thus far aren't changing...Read more
Overall, cancer deaths continue to decline, but the news isn't universally good. Between 2001 and 2018, lung cancer deaths steeply declined, as did rates for melanoma, female breast and colorectal cancers.
Cancer incidence rates are higher for men, but increasing among women. Black people have lower rates of cancer incidence than white people...Read more
It's a question often asked these days: Who will take care of the caregivers? Usually, it's asked in the context of health care workers laid low by COVID-19, resulting in severe staff shortages at hospitals and elsewhere.
But the question applies as well to mental health. New Centers for Disease Control and Prevention research surveying more ...Read more
