Vaccine Refusal Will Come at a Cost—For All of Us
Imagine it's 2026. A man shows up in an emergency room, wheezing. He's got pneumonia, and it's hitting him hard. He tells one of the doctors that he had COVID-19 a few years earlier, in late 2021. He had refused to get vaccinated, and ended up contracting the coronavirus months after most people got their shots. Why did he refuse? Something about politics, or pushing back on government control, o

Pillar of support: Breakthrough discovery could speed up bone implant recovery
A research team has uncovered a new technique that can speed up recovery from bone replacements. Novel micropillars, 10 times smaller than the width of a human hair, can change the size, shape and nucleus of individual stem cells and 'trick' them to become bone. Further research will look to improve the process of locking bone replacements with reduced risk of infection.

According to market researcher, Mintel, 64 percent of guys don't consider men's skincare " an important factor " in their daily grooming, which is a shame—men's skin is uniquely different from women's.

Progress on Bionic Eye
Some terms created for science fiction eventually are adopted when the technology they anticipate comes to pass. In this case, we can thank The Six Million Dollar Man for popularizing the term "bionic" which was originally coined by Jack E. Steele in August 1958. The term is a portmanteau of biological and electronic, plus it just sounds cools and does roll off the tongue, so it's a keeper. So wh

Imbalance in gum bacteria linked to Alzheimer's disease biomarker
Older adults with more harmful than healthy bacteria in their gums are more likely to have evidence for amyloid beta–a key biomarker for Alzheimer's disease–in their cerebrospinal fluid, according to new research from NYU College of Dentistry and Weill Cornell Medicine. However, this imbalance in oral bacteria was not associated with another Alzheimer's biomarker called tau.

"Return the National Parks to the Tribes" — For The Atlantic's May issue, David Treuer makes a forceful moral case that the jewels of America's landscape should belong to America's original peoples.
"The idea of a virgin American wilderness—an Eden untouched by humans and devoid of sin—is an illusion. The national parks are sometimes called 'America's best idea,' and there is much to recommend them. They are indeed awesome places, worthy of reverence and preservation, as Native Americans like me would be the first to tell you. But all of them were founded on land that was once ours, and many
