In the midst of another national debate over gun safety regulations, some argue that higher rates of gun ownership will protect people from dangerous strangers with deadly intentions. Physician and public health researcher Michael Siegel set out to study that argument. He ultimately found no relationship between gun ownership and stranger-related firearm homicides. But he did find that gun ownership levels translated into higher homicide risks for one group in particular — women.
Each year, the U.S. spends $26.2 billion on costs associated with preterm birth — that’s birth before 37 weeks of pregnancy. Beyond the costs, babies born too early experience immediate and long-term problems, from developmental disabilities to asthma to hearing loss. For years, scientists have been studying possible environmental contributors, with many finding an association between preterm birth and air pollution. Earlier this week, a new study brought even more depth and clarity to this connection.
It’s been nearly two decades since the last publication of a nationwide survey on the distribution of blacklegged ticks — the primary transmitters of Lyme disease. That survey, released in 1998, reported the tick in 30 percent of U.S. counties. Today, a new study using similar surveillance methods has found the tick in more than 45 percent of counties.
Scientists are finding that night shift work comes with a range of particular health risks, from heart disease to diabetes to breast cancer. This month, another study joined the pack — this one on the risk of traffic crashes among those who head home from work at sunrise.
These days, there’s a lot of attention on finding new and creative ways to turn around the nation’s opioid abuse and overdose problem. And it’s attention that’s very much needed because the problem is only getting worse.
Re-run from May 27, 2015: For more than a decade, biologist Mariam Barlow has been working on the theory that administering antibiotics on a rotating basis could be a solution to antibiotic resistance. After years of research, Barlow had lots of data, but she needed a more precise way to make sense of it all — something that was so specific it could easily be used to treat patients. So, she joined forces with a team of mathematicians. And the amazing results could help solve an enormous, worldwide problem.
Researcher Douglas Wiebe first started studying gun violence as a doctoral student, investigating how having a firearm in one’s home affected the risk of injury. The work only heightened his interest in exploring gun violence from a public health perspective. Eventually, he decided to officially take on a question he’d been mulling over for almost a decade: Among people who’ve experienced a violent assault, are there any commonalities in their experiences just prior to the incident, and can we map those experiences in a way that reveals optimal intervention opportunities?
In a recent study, Harvard public health researchers decided to test a few dozen types of electronic cigarettes for diacetyl, a flavoring chemical associated with a severe respiratory disease known as “popcorn lung.” The researchers found diacetyl in a majority of the e-cigarettes they tested. News outlets jumped on the findings, with some announcing that e-cigarettes could cause the often-debilitating respiratory disease.
