Last year, Joan Peay slipped on her garage steps and smashed her knee on the welcome mat. Peay, 77, is no stranger to pain. The Tennessee retiree has had 17 surgeries in the last 35 years — knee replacements, hip replacements, back surgery. She even survived a 2012 fungal meningitis outbreak that sickened her and hundreds of others, and killed 64. This knee injury, though, “hurt like the...
Health care quality and availability improved globally from 1990 to 2015, but the gap between the haves and the have-nots widened in those 25 years, researchers report online May 18 in the Lancet.
As an approximate measure of citizens’ access to quality health care, an international team of researchers analyzed mortality rates for 32 diseases and injuries that are typically not fatal...
Most visitors to a large natural history museum don’t know it, but they are only scratching the surface of the museum’s holdings, even if they check out every exhibition. Most of the scientific treasures are tucked away in collection rooms filled with millions of specimens, which scientists use in their research.
The Field Museum in Chicago, home to Sue, the famous T. rex, is displaying...
A black hole weighing more than a billion suns appears to have gotten the boot toward the outer edges of its galaxy.
Data from the Hubble Space Telescope and other observatories reveal a supermassive black hole zipping away from the center of its galaxy at a 7.5-million-kilometer-per-hour clip. It’s moving so quickly that it could leave the galaxy for good in 20 million years, says Marco...
Not too long ago, the internet was stationary. Most often, we’d browse the Web from a desktop computer in our living room or office. If we were feeling really adventurous, maybe we’d cart our laptop to a coffee shop. Looking back, those days seem quaint.
Today, the internet moves through our lives with us. We hunt Pokémon as we shuffle down the sidewalk. We text at red lights. We tweet...

Researchers uncovered the fossilized voice box, called a syrinx, of an ancient bird that lived 68 million to 66 million years ago. The bird may have sounded like a honking duck, Meghan Rosen reported in “Ancient avian voice box unearthed” (SN: 11/12/16, p. 7).
Online reader David Spector wondered if researchers could 3-D print the syrinx to replicate the ancient bird’s...
Drug use continued to threaten the health and safety of the American public in 2016, while a hidden menace in drinking water remained a major worry for the people of Flint, Mich.Teen vaping
Vaping has surpassed cigarette smoking among U.S. high school students, according to a report released in 2016 from the National Youth Tobacco Survey. Estimates suggest that some 2.39 million U.S....
It was barely more than half a century ago that the Nobel Prize–winning virologist Sir Frank Macfarlane Burnet mused about the demise of contagions. “To write about infectious disease,” he wrote in 1962, “is almost to write of something that has passed into history.”
If only. In the past several decades, over 300 infectious pathogens have either newly emerged or emerged in new places,...
