'Clear' e-cigarettes linked to greater acute rises in blood pressure and heart rate

The first mRNA vaccine for foot-and-mouth disease (FMD) was recently created in less than 18 months—but how do mRNA animal vaccines work, and how would this one be deployed in an emergency?

After a routine C-section at an Auckland hospital, a mother developed severe pain and what seemed like postnatal fatigue. It turned out to be an infection with methicillin-resistant Staphylococcus aureus (MRSA), a "superbug" spreading across New Zealand and beyond.

Videos promoting #testosteronemaxxing are racking up millions of views. Like "looksmaxxing" or "fibermaxxing" this trend takes something related to body image (improving your looks) or health (eating a lot of fiber) and pushes it to extreme levels.

Research into the multiple impacts of COVID-19 school closures on adolescent well-being has been published in a key journal.

Ticks are hitching a free ride to the US from different parts of the world, raising concerns among scientists. In a recent study, researchers reported the introduction of seven exotic tick species to Connecticut, U.S., by travelers between 2019 and 2023. The identified ticks were natives of Germany, Guatemala, Costa Rica, Poland, Scotland, Tanzania, and Belize.

For the newest generation of U.S. veterans, transitioning to civilian life can pose profound challenges. Post-9/11 veterans are younger and more diverse, and they face rising rates of trauma, mental health conditions, underemployment and service-connected disabilities, according to a research team at Penn State. To help veterans tackle these hurdles, the researchers created an online assessment tool that assists veteran-serving organizations identify individualized risks and provide targeted, evidence-informed support.

Recently, I've repeatedly come across tragic news reports of children killed in electric scooter, or e-scooter, crashes.

A research group led by the University of Osaka has discovered that the DNA repair enzyme Polβ plays a crucial role in protecting the developing brain from harmful mutations. The study found that a lack of Polβ leads to a significant increase in small insertions and deletions of DNA, known as indels near CpG sites, which are important regulatory regions in genes. This accumulation of mutations could contribute to neurodevelopmental disorders.

Most folks probably think of gene mutations as something people are born with, but genes can also change later in life, sometimes making people sick.

A new study has found that people who lived in areas with high levels of leaded gasoline emissions in the 1960s and '70s are more likely to report memory problems today—a finding that researchers say could deepen our understanding of environmental risks tied to dementia.

For years, state lawmakers have taken the lead on regulating kratom—the controversial herbal supplement used for pain relief, anxiety and opioid withdrawal symptoms. Some states have banned it entirely. Others have passed laws requiring age limits, labeling and lab testing.

Scientists at the National Institutes of Health (NIH) have successfully reduced the severity of late-onset Tay-Sachs (LOTS) disease in human cell cultures and a mouse model by using a novel gene-editing treatment.

Amblyopia, also known as "lazy eye," is a common eye condition in kids that develops when a child has an eye that does not see well. This is caused by a poor connection between the eye to the brain, which can happen for a variety of different reasons. Amblyopia is more common in one eye but can also happen in both eyes.

COVID-19 rates in the Southwestern United States reached 12.5%—the highest in the nation—according to new data from the U.S. Centers for Disease Control and Prevention. Meanwhile, Los Angeles County recorded the highest COVID-19 levels in its wastewater since February.

Substance use recovery is a lifelong process, but environmental triggers, such as alcohol at social gatherings or pain medication advertisements, can put individuals in recovery at risk of relapse.
