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 Research challenges current thinking on the genetic causes of very early menopause (via sciencedaily.com) Original source
The genetic causes of very early menopause will have to be reconsidered after researchers found that nearly all women who carried variations thought to cause the condition in fact had their menopause at an older age.
Published Helping 'good' gut bacteria and clearing out the 'bad' -- all in one treatment (via sciencedaily.com) Original source
Probiotics can help maintain a healthy gut microbiome or restore populations of 'good bacteria' after a heavy course of antibiotics. But now, they could also be used as an effective treatment strategy for certain intestinal diseases, such as Crohn's disease. Researchers have developed a microgel delivery system for probiotics that keeps 'good' bacteria safe while actively clearing out 'bad' ones. In mice, the system treated intestinal inflammation without side effects.
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 A 'pinch' of mineral salts helps the noncaloric sweeteners go down (via sciencedaily.com) Original source
Perfect noncaloric replacements for sugar and high fructose corn syrup just don't exist yet. For example, some alternatives have a lingering sweet aftertaste and lack a sugar-like mouthfeel, leaving some consumers unsatisfied. Now, researchers propose adding blends of nutritionally important mineral salts to make noncaloric sweeteners seem more like the real thing. Taste-testers indicated that these blends gave zero- and low-calorie drinks a better flavor.
Published New study links contraceptive pills and depression (via sciencedaily.com) Original source
Women who used combined contraceptive pills were at greater risk of developing depression than women who did not, according to a new study. Contraceptive pills increased women's risk by 73 per cent during the first two years of use.
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 How breast cancer arises (via sciencedaily.com) Original source
Researchers trace the origin of certain breast cancers to genomic reshuffling -- rearrangement of chromosomes -- that activates cancer genes and ignites disease. The finding offers a long-missing explanation for many cases of the disease that remain unexplained by the classical model of breast cancer development. The study shows the sex hormone estrogen -- thus far thought to be only a fuel for breast cancer growth -- can directly cause tumor-driving genomic rearrangements.
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 Gamma delta T cells can fight aggressive breast cancer (via sciencedaily.com) Original source
Researchers discover a mechanism by which cancer cells escape the immune system.
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 '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 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 Osteoporosis treatments may benefit from discovery of key driver of low bone density (via sciencedaily.com) Original source
Scientists have pinpointed a key driver of low bone density, a discovery that may lead to improved treatments with fewer side effects for women with osteoporosis. The findings reveal that loss of an epigenetic modulator, KDM5C, preserves bone mass in mice. KDM5C works by altering epigenetic 'marks,' which are akin to 'on' and 'off' switches that ensure the instructions written in DNA are used at the right time and in the right place.
Published Early menopause, later start to hormone therapy may increase risk of Alzheimer's disease (via sciencedaily.com) Original source
Women are more likely than men to develop Alzheimer's disease (AD), with women making up two-thirds of the population living with AD. A new study sheds light on the relationship between the risk of Alzheimer's disease and age of menopause and use of hormone therapy (HT).
Published Is bone health linked to brain health? (via sciencedaily.com) Original source
People who have low bone density may have an increased risk of developing dementia compared to people who have higher bone density. The study does not prove that low bone density causes dementia. It only shows an association.
Published Study finds similar association of progestogen-only and combined hormonal contraceptives with breast cancer risk (via sciencedaily.com) Original source
There is a relative increase of 20% to 30% in breast cancer risk associated with both combined and progesterone-only contraceptives, whatever the mode of delivery, though with five years of use, the 15-year absolute excess incidence is at most 265 cases per 100,000 users, according to a new study.
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.
Published Disproportionate percentage of females with unexplained infertility have gene variants known to cause heart problems, cancer (via sciencedaily.com) Original source
About 17% of women with unexplained infertility also have gene variants known to cause disease, from common conditions like heart disease to rare problems like ALS, researchers report.
