New research validates a tool for measuring how disgusted people are by body odors, revealing that this trait is tied to germ avoidance, not general anxiety. Women tend to score higher, and the trait predicted COVID-19 caution.
Retinol is the most widely studied anti-aging skincare ingredient, shown to reduce wrinkles, boost collagen, and improve skin texture. A 2025 clinical trial also tested a new cyclic peptide (CHP-9) against retinol, with promising early results, though retinol remains the better-studied option.
Growth hormone secretagogues affect more than just height. Recent research explores how the ghrelin signaling system influences childhood growth treatment, brain health in Alzheimer's disease, and immune system inflammation.
A 2025 study found that dumbbell and cable lateral raises produce identical lateral deltoid growth in trained lifters. Meanwhile, research on elbow angle suggests keeping your arm straighter may increase muscle activation. Here is what the evidence means for your shoulder training.
New research breaks down the science of bodybuilding nutrition, from protein targets and post-workout recovery to what 33 top coaches actually recommend. Here's where coaching wisdom and lab evidence agree, and where they don't.
Not all protein is absorbed equally by your body. A controlled trial found that animal-based protein foods deliver significantly more usable amino acids per serving than plant-based foods, even when portions are labeled as 'equivalent' by dietary guidelines. But the full story is more nuanced than that.
Finasteride is a widely used drug for hair loss and enlarged prostate, but a small number of men report persistent sexual, psychological, and metabolic symptoms after stopping it. Recent studies examine genetics, metabolic mechanisms, and FDA reporting data to understand what's behind post-finasteride syndrome.
Your lats are the biggest muscle in your body, yet they have been surprisingly understudied. New research reveals how they grow at the fiber level, whether extra protein helps, and why your grip width on the pulldown barely matters.
Recent studies show that a simpler, dye-free MRI can detect prostate cancer just as well as the standard version. Meanwhile, MRI plays a growing role in thyroid cancer staging and rectal cancer treatment decisions, though no single imaging tool is perfect for every situation.
Not all nutrient forms are absorbed equally. A 2025 review of vitamin C supplements found that alternative forms like calcium ascorbate and liposomal vitamin C can deliver more of the vitamin to immune cells than standard ascorbic acid. Meanwhile, research on plant polyphenols shows that gut bacteria and dietary fiber play a crucial role in unlocking their health benefits.
