During a recent two-year period, almost 23 percent of U.S. adults ages 18 to 59 had a type of genital human papillomavirus (HPV) that put them at high risk of certain cancers, according to a Centers for Disease Control and Prevention report published Thursday. That percentage jumped to more than 42 percent during 2013 to 2014 if any type of genital HPV was included, the CDC found. In both groups, prevalence was higher in men than in women, and it was sharply higher among blacks compared to other racial and ethnic groups. (Naqvi, 4/6)

Long-term use of aspirin is associated with lower risk of dying from various types of cancers, including colorectal, lung, breast and prostate cancer, according to a study presented at the 2017 American Association for Cancer Research Annual Meeting on Monday. The longitudinal study analyzed the association of aspirin, with varied doses and duration of use, on overall mortality risks and mortality risks from cancer over a nearly 32-year period.

More than half of the babies born in Cuyahoga County in 2015 who died before reaching a first birthday were born premature, and most of those infants were born so early they had almost no chance of surviving. More than two thirds of the premature babies who died in the county that year were black, and many were born to mothers who had early access to good prenatal care. (Zeltner, 4/5)

Of the many pesticides that American farmers have embraced in their war on bugs, neonicotinoids are among the most popular. One of them, called imidacloprid, is among the world’s best-selling insecticides, boasting sales of over $1 billion a year. But with their widespread use comes a notorious reputation — that neonics, as they are nicknamed, are a bee killer. A 2016 study suggested a link between neonicotinoid use and local pollinator extinctions, though other agricultural researchers contested the pesticides' bad rap. (Guarino, 4/5)

Millions of Americans take an ambulance trip every year; others get rides from willing friends or, tempting fate, drive themselves. But in recent years a new trend has arisen: Instead of an ambulance, some sick people are hailing an emergency Uber. Though firm numbers are hard to come by, drivers for Uber and Lyft say it happens with some regularity. In an online chatroom for Uber drivers, dozens of posters share experiences with passengers who hail a ride with bloody cuts, asthma, anaphylaxis, or broken bones.

Do you pop up from your seat during meetings and finish other people's sentences? And maybe you also procrastinate, or find yourself zoning out in the middle of one-on-one conversations? It's possible you have adult ADHD. (Hersher, 4/5)

In emergencies, administering drugs quickly and easily can be a matter of life and death. This has emergency departments turning to the nose as a delivery route because it's so accessible and doesn't require direct contact with a needle. Using the nose as a passage for steroids like Flonase and vaccines like FluMist has been common practice for decades. In recent years, more Americans have also become aware of the emergency drug naloxone, which is used to reverse the effects of an opioid overdose, even when someone has stopped breathing.

A surprising medical finding caught the eye of NPR's veteran science correspondent Richard Harris in 2014. A scientist from the drug company Amgen had reviewed the results of 53 studies that were originally thought to be highly promising — findings likely to lead to important new drugs. But when the Amgen scientist tried to replicate those promising results, in most cases he couldn't. "He tried to reproduce them all," Harris tells Morning Edition host David Greene. "And of those 53, he found he could only reproduce six." (4/6)
