A bill seeking to preserve abortion protections in state law fails to pass a key committee. Lawmakers cite God, church and faith in proclaiming their opposition to it. Abortion-rights groups protest outside a gathering of lawmakers. What sounds like a legislative fight in a state controlled by anti-abortion Republicans is actually quite different. The bill seeking to protect abortion rights...

Five years after Colorado first legalized marijuana, a new study shows pot’s bad effects are sending more people to the emergency room.

After a few years of being clean from heroin, Courtney Nunnally decided she wanted to use her own experience to help others. Under an innovative program in Virginia, she rides along with police to tell addicts: If I could recover, so can you.

The government’s top doctor is taking aim at the best-selling electronic cigarette brand in the U.S., urging swift action to prevent Juul and similar vaping brands from addicting millions of teenagers. In an advisory Tuesday, Surgeon General Jerome Adams said parents, teachers, health professionals and government officials must take “aggressive steps” to keep children from using e-cigarettes. Federal law bars...

Twice as many high school students used nicotine-tinged electronic cigarettes this year compared with last year, an unprecedented jump in a large annual survey of teen smoking, drinking and drug use. It was the largest single-year increase in the survey’s 44-year history, far surpassing a mid-1970s surge in marijuana smoking. The findings, released Monday, echo those of a government survey...

Are poinsettias really poisonous? Are snowflakes really pure as the driven snow? Does feasting really put on the pounds? Sure as sugarplums, myths and misconceptions pop up every holiday season. Here’s what science says about some of them.

Forensic experts worked Friday on the grim task of identifying dozens of bodies charred beyond recognition by the eruption of Guatemala’s Volcano of Fire, a disaster that has left at least 110 confirmed dead and nearly 200 still missing.

Government and other scientists are proposing a new way to define Alzheimer’s disease — basing it on biological signs, such as brain changes, rather than memory loss and other symptoms of dementia that are used today. The move is aimed at improving research, by using more objective criteria like brain scans to pick patients for studies and enroll them sooner...

Take two tablets and a selfie? Your doctor’s orders may one day include a smartphone video to make sure you took your medicine. Smartphone apps that monitor pill-taking are now available, and researchers are testing how well they work when medication matters.

It’s pretty extraordinary for people in their 80s and 90s to keep the same sharp memory as someone several decades younger, and now scientists are peeking into the brains of these “superagers” to uncover their secret. The work is the flip side of the disappointing hunt for new drugs to fight or prevent Alzheimer’s disease.

In perhaps an unexpected twist, historically conservative strongholds like Oklahoma and West Virginia are leading efforts to bring preschool to all. “They have in common a low-wage workforce, relatively low education levels and the desire to change that,” said Steven Barnett of the National Institute for Early Education Research. “Whatever they say, politicians in West Virginia know the future of...
