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.

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

That's $400 million more than in 2012. Spending on Spanish advertising in 2019 increased 33% since ...Read more

Scientists recently sent freeze-dried mouse sperm into low-Earth orbit to study the effects of space radiation on fertility and reproduction. After spending between three and six years aboard the International Space Station, the researchers brought the sperm samples back and thawed them to produce healthy mouse pups.

They found gene ...Read more

Researchers say that for patients with clinical depression who do not improve with antidepressant medications, the remedy might be nitrous oxide, otherwise known as laughing gas.

A small study found that a low dose of laughing gas was just as effective at improving depression as a higher dose of standard medications in patients with treatment...Read more

In the early months of the pandemic, telehealth use rose dramatically. But fewer people are using digital tools to connect with their doctor these days. Claims for telehealth service fell 5% in March of this year from February, which fell 16% from January.
