While it’s easy to recognize when we’re under intense stress, identifying low-level, chronic stress that lingers in the background is much more challenging. To help with this, researchers at Tufts University have developed a new type of dental floss that can analyze your saliva and provide insight into your stress levels. The Biological Impact of […]

After discovering the blood vessels responsible for finger wrinkles in water, young readers of The Conversation’s Curious Kids series had more questions for scientists: “Do the wrinkles always form the same way?” one reader asked. Curiosity Sparks a Scientific Investigation “I thought, ‘I haven’t the foggiest clue!‘” recalls Guy German, a biomedical engineer from Binghamton

A new study has uncovered a method to prevent cell death, potentially paving the way for treatments that could slow the progression of neurodegenerative diseases such as Parkinson’s. Apoptosis, the body’s ancient “cell suicide” mechanism, is controlled by interactions within the BCL-2 protein family. While some of these proteins support cell survival, others initiate cell
Whoop has partially retreated from its contentious upgrade policy for the Whoop 5.0 fitness tracker. Initially, when the company unveiled the Whoop 5.0 this week, it told members they could receive the new device by either extending their subscriptions by 12 months or paying a one-time upgrade fee of $49—or $79 for the version with
