Before ever entering a residence hall, students moving to campus will spit in a tube, hand it over and wait just 45 minutes for their COVID-19 test results.

Attention to climate change has rapidly declined in recent months. That's concerning, say study authors who found that simply directing one's attention to an environmental risk—even briefly and involuntarily—makes people more concerned and willing to take action.

Researchers from the BioFrontiers Institute at CU Â鶹¹ÙÍø have developed a saliva-based COVID-19 test capable of returning results in as little as 45 minutes—no nasal swabs or fancy laboratory equipment required. It could potentially be used for mass, inexpensive screening in community settings like schools and factories.

If each human cell has the same blueprint, or set of genes, why does an eye cell look and act differently than a brain cell or skin cell? New research moves science one step closer to solving this mystery, potentially leading to new treatments for cancer, heart abnormalities and more.

As many as 7% of moms-to-be use marijuana while pregnant, and that number is rising fast as more use it as a remedy for morning sickness. But new research shows such use could have a lasting impact on the fetal brain, influencing children's sleep for as much as a decade.

Eat a slab of steak and your resident gut bacteria get to work immediately to break it down. But new research shows that a metabolic byproduct, called TMAO, produced in the process can be toxic to the lining of arteries, making them age faster.

Extremely conservative Facebook users are responsible for sharing the bulk of fake news, but extreme liberals are responsible for a good chunk of it, too, according to a new study. Those who lack trust in the media, and in society in general, are also more likely to share it.

Students are sleeping about a half-hour more each night and keeping more regular sleep hours. That's positive news, said study authors, as sleep is key to maintaining overall health, including a robust immune system that can fight off viruses.

Smoking high-potency marijuana concentrates boosts blood levels of THC more than twice as much as smoking conventional weed, but it doesn’t necessarily get you higher, according to a new study. The research also found that memory and balance are impaired immediately after using cannabis, but those impairments subside in an hour.

Youth programs designed to prevent drug use and delinquency and support healthy development can reap lasting benefits not only for participants, but also for their kids.
