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.

Published Want the secret to less painful belly flops? These researchers have the answer (via sciencedaily.com) Original source
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 Researchers reveal link between Alzheimer's and sex hormones (via sciencedaily.com) Original source
Researchers have shown female sex hormones play a significant role in how Alzheimer's manifests in the brain. The study also highlights the importance of developing therapeutic strategies focused on these hormonal connections. The research indicates a need to better understand the role of estradiol -- a form of the female sex hormone estrogen, used therapeutically to mitigate menopause symptoms -- in Alzheimer's disease.
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 Women living in more walkable neighborhoods have lower rates of obesity-related cancers (via sciencedaily.com) Original source
Residing in a more walkable neighborhood protects against the risk of overall obesity-related cancers in women, specifically postmenopausal breast cancer, but also ovarian cancer, endometrial cancer, and multiple myeloma, according to a new study. Obesity has been linked to increased risk for 13 types of cancer in women, and physical activity, independent of body size, lowers risk for some of these cancers. Until now long-term studies of neighborhood walkability and risk for obesity-related cancer were limited.
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 Is a longer reproductive lifespan good for your brain? (via sciencedaily.com) Original source
People with a higher cumulative estrogen exposure throughout their life may have a lower risk of cerebral small vessel disease, according to a new study.
Published Women given new insight into blood clot risk (via sciencedaily.com) Original source
New research shows an increased risk of blood clots in women who have any combination of a particular gene mutation, estrogen use, or common medical conditions -- specifically: obesity, high blood pressure, high cholesterol, and kidney 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 Women with PCOS on keto diet may see improvements in fertility (via sciencedaily.com) Original source
The ketogenic (keto) diet may lower testosterone levels in women with polycystic ovary syndrome (PCOS), according to a new article.
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 Review of over 70 years of menopause science highlights research gaps and calls for individualized treatment (via sciencedaily.com) Original source
Although about half of people go through menopause, less than 15% of them receive effective treatment for their symptoms. Treatment options for people experiencing irritating or severe menopause symptoms are often under researched, and some have questionable efficacy, or cause harmful side effects. Menopause experts now summarize what we know about menopause, call for more research into the timeline and treatment of menopause, and encourage individualized, holistic treatment that addresses both menopausal symptoms and other systemic changes happening in the body.
