Published Grocery store carts set to help diagnose common heart rhythm disorder and prevent stroke (via sciencedaily.com) Original source
It could be the shopping trip that saves your life: supermarket trolleys are helping to diagnose atrial fibrillation which can then be treated to prevent disabling or fatal strokes.
Published Illusions are in the eye, not the mind (via sciencedaily.com) Original source
Numerous visual illusions are caused by limits in the way our eyes and visual neurones work -- rather than more complex psychological processes, new research shows.
Published New research identifies cells linking chronic psychological stress to inflammatory bowel disease (via sciencedaily.com) Original source
For the first time, cells involved with the communication between stress responses in the brain and inflammation in the gastrointestinal (GI) tract have been identified in animal models. Glial cells, which support neurons, communicate stress signals from the central nervous system (CNS) to the semi-autonomous nervous system within the gastrointestinal (GI) tract, called the enteric nervous system (ENS). These psychological stress signals can cause inflammation and exacerbate symptoms of inflammatory bowel disease (IBD).
Published How chronic stress drives the brain to crave comfort food (via sciencedaily.com) Original source
Stress can override natural satiety cues to drive more food intake and boost cravings for sweets.
Published Amputees feel warmth in their missing hand (via sciencedaily.com) Original source
An unexpected discovery about temperature feedback has led to new bionic technology that allows amputees to sense the temperature of objects ¬-- both hot and cold -- directly in the phantom hand. The technology opens up new avenues for non-invasive prosthetics.
Published Researchers discover brain circuit underlying spontaneous synchronized movement of individuals in groups (via sciencedaily.com) Original source
Individual fish in schools scatter in unison when a predator is in their midst. Such precisely coordinated group movements and immobility during threats have long been observed in insects and mammals. Now, a brain pathway has been discovered that enables individual animals to rapidly coordinate a unified response, with no rehearsal required.
Published Anti-depressant agent KNT-127 reduces stress as well as depression (via sciencedaily.com) Original source
Depression is a condition affecting millions across the globe. However, efficient drugs with minimal adverse effects are scarce. Now, researchers have reported how KNT-127, a delta opioid receptor agonist, quickly and efficiently reduces classic parameters of depression in a mouse model. This anti-depressant agent exhibits the dual nature of being a stress reliever and an anti-depressant and could broaden the potential of existing treatments.
Published Why do Champagne bubbles rise the way they do? Scientists' new discovery is worthy of a toast (via sciencedaily.com) Original source
ere are some scientific findings worthy of a toast: Researchers have explained why bubbles in Champagne fizz up in a straight line while bubbles in other carbonated drinks, like beer or soda, don’t.
Published Sleep phase can reduce anxiety in people with PTSD (via sciencedaily.com) Original source
A new study shows that sleep spindles, brief bursts of brain activity occurring during one phase of sleep and captured by EEG, may regulate anxiety in people with post-traumatic stress disorder (PTSD).
Published 'Gluing' soft materials without glue (via sciencedaily.com) Original source
If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.
Published Stress increases Alzheimer's risk in female mice but not males (via sciencedaily.com) Original source
Stress causes the levels of Alzheimer's proteins to rise in females' brains but not males' brains, according to a new study. This difference may contribute to women's greater risk of developing Alzheimer's disease.
Published Cannabinoids give worms the munchies, too (via sciencedaily.com) Original source
Marijuana (cannabis) is well known for giving people the 'munchies.' Not only does it make people want to eat more, but it also makes them crave the tastiest, most high-calorie foods. Now a new study shows that well-studied nematode worms (C. elegans) react to those chemicals known as cannabinoids in precisely the same way.
Published Chitin from consuming insects can help both gut microbiota and global health (via sciencedaily.com) Original source
Increased insect consumption by humans may be better for both gut health and planetary health. Chitin (kai'tin) and healthy fats from insects appear to contribute to healthy gut microbiota and are strong sources of protein and nutrients, according to a recent paper.
Published Impact of maternal stress during pregnancy on child's health (via sciencedaily.com) Original source
New research examines the impact that maternal stress during pregnancy has on the neuro-development of babies.
Published Detecting stress in the office from how people type and click (via sciencedaily.com) Original source
Researchers have developed a model that detects workplace stress just by how people type and move their computer mouse. This might enable employees to prevent chronic stress early on.
Published Teachers who struggle to cope with stress report far lower job satisfaction (via sciencedaily.com) Original source
As teacher shortages continue to worsen across the United States, a new study gives insight into why so many stressed and burnt-out teachers are leaving the profession. The study found teachers who struggle to cope with the stress of their job report far lower job satisfaction compared to teachers who find ways to manage the pressure.
Published Study examines how social rank affects response to stress (via sciencedaily.com) Original source
Scientists say their study could shed light on stress-related mental illnesses but that more research is needed.
Published Positive experiences in close relationships are associated with better physical health, new research suggests (via sciencedaily.com) Original source
Social relationships influence physical health, but questions remain about the nature of this connection. New research suggests that the way you feel about your close relationships may be affecting the way your body functions.
Published Study finds worrying about election stress can harm your health -- and what you can do about it (via sciencedaily.com) Original source
New research finds that simply anticipating stress related to political elections causes adverse physical health effects. However, the study also finds there is something people can do to mitigate those negative health effects.
Published Vocal tract size, shape dictate speech sounds (via sciencedaily.com) Original source
Researchers explore how anatomical variations in a speaker's vocal tract affect speech production. Using MRI, the team recorded the shape of the vocal tract for 41 speakers as the subjects produced a series of representative speech sounds. They averaged these shapes to establish a sound-independent model of the vocal tract. Then they used statistical analysis to extract the main variations between speakers. A handful of factors explained nearly 90% of the differences between speakers.
