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 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 Traditional medicine plant could combat drug-resistant malaria (via sciencedaily.com) Original source
Much of what is now considered modern medicine originated as folk remedies or traditional, Indigenous practices. These customs are still alive today, and they could help address a variety of conditions. Now, researchers have identified compounds in the leaves of a particular medicinal Labrador tea plant used throughout the First Nations of Nunavik, Canada, and demonstrated that one of them has activity against the parasite responsible for malaria.
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 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 Innovative breathing aid developed (via sciencedaily.com) Original source
One in 10 adults suffer from the debilitating effects of chronic obstructive pulmonary disease (COPD). Research around a new breathing device developed by pulmonologists offers promise for improving their lives. The new device not only improves symptoms of breathlessness and quality of life for people with COPD, it also offers benefits for people dealing with stress and anxiety and those practicing mindfulness, meditation or yoga. The research was published in the journal Respiratory Care.
Published Virtual reality games can be used as a tool in personnel assessment (via sciencedaily.com) Original source
Fast gamers are more intelligent: Intelligence can be predicted through virtual reality games.
Published Edible electronics: How a seaweed second skin could transform health and fitness sensor tech (via sciencedaily.com) Original source
Scientists have developed biodegradable algae-based hydrogels for strain sensing devices -- such as those used in health monitors worn by runners and hospital patients to track heart rate -- using natural elements like rock salt, water and seaweed, combined with graphene. As well as being more environmentally friendly than polymer-based hydrogels, commonly used in health sensor technology, the graphene algae sensors perform strongly in terms of sensitivity.
Published Wireless, soft e-skin for interactive touch communication in the virtual world (via sciencedaily.com) Original source
Sensing a hug from each other via the internet may be a possibility in the near future. A research team recently developed a wireless, soft e-skin that can both detect and deliver the sense of touch, and form a touch network allowing one-to-multiuser interaction. It offers great potential for enhancing the immersion of distance touch communication.
Published U.S. study of intravenous mistletoe extract to treat advanced cancer (via sciencedaily.com) Original source
Researchers completed what is believed to be the first phase I trial of intravenous Helixor M in the U.S. aimed at determining dosing for subsequent clinical trials and to evaluate safety.
Published Want healthy Valentine chocolates? We can print them (via sciencedaily.com) Original source
A scientist has developed a formulation of low-fat chocolate that can be printed on a 3D printer in pretty much any shape a person can conceive, including a heart.
Published Discovery of anti-cancer chemistry makes skullcap fit for modern medicine (via sciencedaily.com) Original source
The evolutionary secrets that enable the medicinal herb known as barbed skullcap to produce cancer fighting compounds have been unlocked.
Published Human-approved medication brings back 'lost' memories in mice (via sciencedaily.com) Original source
Students sometimes pull an all-nighter to prepare for an exam. However, research has shown that sleep deprivation is bad for your memory. Now, neuroscientists have discovered that what you learn while being sleep deprived is not necessarily lost, it is just difficult to recall. Together with his team, he has found a way to make this 'hidden knowledge' accessible again.
Published Drinking 2 or more cups of coffee daily may double risk of heart death in people with severe hypertension (via sciencedaily.com) Original source
Drinking two or more cups of coffee a day was associated with twice the risk of death from cardiovascular disease among people with severe hypertension compared to non-coffee drinkers, in a study of more than 18,600 men and women in Japan.
Published See no evil: People find good in villains (via sciencedaily.com) Original source
No matter how egotistical, power hungry or greedy the person is, many of us are still attracted to their dark side -- in part because we suspect some may have a redeeming quality. A recent study found that both adults and children more often reported that villains were inwardly good than that heroes were inwardly bad.
