Researchers identify a mechanism that can help guide the development of new STING-activating drugs using imaging

A new study from scientists at the UCLA Jonsson Comprehensive Cancer Center found that emerging drugs that activate the protein STING, a well-established regulator of immune cell activation, substantially alter the activity of metabolic pathways responsible for generating the nucleotide building blocks for DNA. Researchers found that these alterations occur in cancer cells and can

Can a heartburn drug help doctors treat COVID-19?

In the early days of the COVID-19 pandemic, doctors in Wuhan noticed something surprising. Many of the elderly patients who survived the virus were poor: not exactly the demographic you would expect to fare well in a health crisis. A review of the survivors’ medical records revealed that a significant number suffered from chronic heartburn

How a doctor’s presence may alter blood pressure readings

A doctor’s presence during a blood pressure reading triggers a “fight or flight” response that can affect the results, say researchers who studied the effect by measuring nerve activity. “White coat hypertension”—the phenomenon when blood pressure rises in some people who are measured by a medical professional—has been known about for decades. It occurs in

Text reminders boost vaccine appointments

Coronavirus infections among vaccinated people are on the decline but for the unvaccinated, cases continue to increase. Researchers at Carnegie Mellon University and the University of California, Los Angeles found text-based nudges are an effective way to remind people to schedule their first COVID-19 vaccination appointment and show up. The results of the study are

Awareness without a sense of self

In the context of meditation practice, meditators can experience a state of ‘pure awareness’ or ‘pure consciousness’, in which they perceive consciousness itself. This state can be experienced in various ways, but evidently incorporates specific sensations as well as non-specific accompanying perceptions, feelings, and thoughts. These are just some of the findings of the most

Q and A: Kidney stones and calcium

DEAR MAYO CLINIC: I have trouble with kidney stones and recently found out they are calcium oxalate stones. While I have stopped consuming all dairy products, I know that I need calcium as I age for bone health. Would adding in almond milk or another type of plant milk help? How do I take care

A brain mechanism that automatically links objects in our minds

When people see a toothbrush, a car, a tree—any individual object—their brain automatically associates it with other things it naturally occurs with, allowing humans to build context for their surroundings and set expectations for the world. By using machine-learning and brain imaging, researchers measured the extent of the “co-occurrence” phenomenon and identified the brain region
