Published Wearables capture body sounds to continuously monitor health (via sciencedaily.com) Original source
From heart beats to stomach gurgles, sounds hold important health information. New wireless devices sit on skin to continuously capture these sounds, then stream data to smartphones or tablets in real time. In pilot studies, devices accurately tracked sounds associated with cardiorespiratory function, gastrointestinal activity, swallowing and respiration. The devices are particularly valuable for premature babies, who can experience apneas and gastrointestinal complications, which are accompanied by sounds.
Published When we see what others do, our brain sees not what we see, but what we expect (via sciencedaily.com) Original source
When we engage in social interactions, like shaking hands or having a conversation, our observation of other people's actions is crucial. But what exactly happens in our brain during this process: how do the different brain regions talk to each other? Researchers provide an intriguing answer: our perception of what others do depends more on what we expect to happen than previously believed.

Researchers investigated belly flop mechanics and found surprising insights about air-to-water impacts that could be useful for marine engineering applications. They set up a belly flop-like water experiment using a blunt cylinder but added an important vibrating twist to it.
Published How 'blue' and 'green' appeared in a language that didn't have words for them (via sciencedaily.com) Original source
A new study suggests the way a language divides up color space can be influenced by contact with other languages. Tsimane' people who learned Spanish as a second language began to classify blue and green into using separate words, which their native tongue does not do.
Published Study suggests even more reasons to eat your fiber (via sciencedaily.com) Original source
Health professionals have long praised the benefits of insoluble fiber for bowel regularity and overall health. New research suggests even more reasons we should be prioritizing fiber in our regular diets. Researchers found that each plant source of insoluble fiber contains unique bioactives -- compounds that have been linked to lower incidence of cardiovascular disease, cancer and Type 2 diabetes -- offering potential health benefits beyond those of the fiber itself.
Published The microbiome of fruit and vegetables positively influences diversity in the gut (via sciencedaily.com) Original source
In a meta-study, a research team has provided evidence that the consumption of fruit and vegetables contributes positively to bacterial diversity in the human gut.
Published Mummified feces reveals pre-Columbian cultures of the Caribbean consumed a diversity of plants (via sciencedaily.com) Original source
DNA analysis of mummified feces reveals two pre-Columbian Caribbean cultures ate a wide variety of plants, like maize, sweet potato, and peanuts -- and tobacco and cotton traces were detected too, according to a new study.
Published Being a vegetarian may be partly in your genes (via sciencedaily.com) Original source
A person's genetic makeup plays a role in determining whether they can stick to a strict vegetarian diet, a new study has found. The findings open the door to further studies that could have important implications regarding dietary recommendations and the production of meat substitutes.
Published Skin behind the ears and between the toes can host a collection of unhealthy microbes (via sciencedaily.com) Original source
Scrubbing behind the ears and between the toes may help keep the skin in those regions healthy, new research suggests. The microbiome, or the collection of microbes living on and in the human body, are known to play a role in human health and the skin is no different. A new study has shown that the composition of the skin microbiome varies across dry, moist and oily regions of the skin.
Published A quarter of people are undoing the benefits of healthy meals by unhealthy snacking (via sciencedaily.com) Original source
A quarter of people are undoing the benefits of healthy meals with unhealthy snacks, which increases the risk of strokes and cardiovascular disease.
Published Your body's own cannabinoid molecules calm you during stress (via sciencedaily.com) Original source
When you're under stress, your brain may release its own cannabinoid molecules to calm you, activating the same brain receptors as THC derived from cannabis plants. But the brain activity regulated by these cannabinoid molecules were not well known. A new study in mice has discovered a key emotional brain center, the amygdala, releases cannabinoid molecules under stress that dampen the incoming stress alarm from the hippocampus, a memory and emotion center in the brain. The finding may reveal novel therapeutic targets for the treatment of stress-related disorders.
Published Lower jersey numbers make football players look thinner (via sciencedaily.com) Original source
Football players sometimes choose jerseys with lower numbers thinking that they'll look slimmer and faster. There's a scientific basis for that belief, according to a new study. In two experiments, volunteers consistently said that images of players in jerseys numbered 10 to 19 looked thinner than players in jerseys numbered 80 to 89, even when the bodies were the same size. The finding suggests that people's previously learned associations between numbers and sizes influence their perceptions of body size.
Published Breathe! The shape-shifting ball that supports mental health (via sciencedaily.com) Original source
A soft ball designed to support mental health by 'personifying' breath has been invented by a computer science student.
Published Research team identifies human odorant receptor for horse stable odor (via sciencedaily.com) Original source
Para-cresol is an aromatic compound with a strong horse stable-like odor. It contributes to the off-flavor of some foods, but it is also detectable as a characteristic odorant in whiskey and tobacco, as well as in the urine of various mammals. A research team has now discovered which odorant receptor humans use to perceive para-cresol.
Published Participating in genetic studies is in your genes (via sciencedaily.com) Original source
Why do some people take part in genetic studies while others do not? The answer may lie within our genetic makeup. According to a groundbreaking study, people who participate in genetic studies are genetically more likely to do so, leaving detectable 'footprints' in genetics data. This breakthrough equips researchers with the ability to identify and address participation bias, a significant challenge in genetic research.
Published These lollipops could 'sweeten' diagnostic testing for kids and adults alike (via sciencedaily.com) Original source
A lollipop might be a sweet reward for a kid who's endured a trip to the doctor's office, but now, this candy could make diagnostic testing during a visit less invasive and more enjoyable. Researchers have shown that a lollipop-based saliva collection system can capture bacteria from adults and remain shelf-stable for up to a year. Study participants also preferred the candies over conventional collection systems.
Published Global diet study challenges advice to limit high-fat dairy foods (via sciencedaily.com) Original source
Unprocessed red meat and whole grains can be included or left out of a healthy diet, according to a study conducted in 80 countries across all inhabited continents. Diets emphasizing fruit, vegetables, dairy (mainly whole-fat), nuts, legumes and fish were linked with a lower risk of cardiovascular disease (CVD) and premature death in all world regions. The addition of unprocessed red meat or whole grains had little impact on outcomes.
Published Not eating enough of these six healthy foods is associated with higher cardiovascular disease and deaths globally (via sciencedaily.com) Original source
Previous and similar research has focused on Western countries and diets that combined harmful, ultra-processed foods with nutrient-dense foods. This research was global in scope and focused on foods commonly considered to be healthy. Researchers derived a diet score from PHRI's ongoing, large-scale global Prospective Urban and Rural Epidemiological (PURE) study, then replicated that in five independent studies to measure health outcomes in different world regions and in people with and without prior CVD.
