When stay-at-home mom Tracy Dixon-Salazar’s toddler developed severe epilepsy, she went to college, earned a PhD, and uncovered a genetic mutation that transformed her child's life.

Mu opioid receptors help regulate the brain’s pain signals, offering clues for developing more targeted, effective chronic pain therapies.

Universities must teach new graduate students the “hidden curriculum” of how academic careers actually work—from funding to networking—starting on day one.

Researchers showed that chemotherapy-resistant cancer cells use fructose to reprogram neighboring cells and facilitate dissemination in mice.

By searching across 2.5 million people, researchers identified variants strongly associated with fibromyalgia, giving clues for unraveling the disease’s mechanisms. 

This postdoctoral researcher explores skeletal muscle biology and cellular signaling that muscle cells use to resist stress and maintain integrity.

MRI studies revealed that both breeding and training have altered dog brain networks linked to communication, leading to new insights in dog-human interactions.

Using live brain tissue, researchers showed that electrical stimulation activates gene expression that leads to increased neuron firing in humans. 

Researchers created a pair of beagles that don’t produce the main allergen that causes dog allergies in people, though the pups are a long way from being available as pets.

A newly identified protein helps Toxoplasma gondii survive oxidative stress while packed inside its cyst, highlighting a potential therapeutic target for the world’s most successful parasite.

Contrary to long-standing views based on mouse studies, bone marrow-derived cells infiltrate the aging human brain, paving the way for brain-targeted cell therapies.

This postdoctoral researcher studies the cellular pathways behind retinal pigment epithelium degeneration and develops neuroprotective strategies to prevent vision loss.
