Published Your body's own cannabinoid molecules calm you during stress (via sciencedaily.com)
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)
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)
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)
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 AI tests into top 1% for original creative thinking (via sciencedaily.com) Original source
New research suggests artificial intelligence can match the top 1% of human thinkers on a standard test for creativity.
Published Taking higher-than-recommended doses of vitamin D for five years reduced the risk of atrial fibrillation (via sciencedaily.com) Original source
Taking higher-than-recommended doses of vitamin D for five years reduced the risk of atrial fibrillation in older men and women, according to a new study.
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 Vitamin D alters developing neurons in the brain's dopamine circuit (via sciencedaily.com) Original source
Neuroscientists have shown how vitamin D deficiency affects developing neurons in the brain's dopamine circuit, which may lead to the dopamine dysfunction seen in adults with schizophrenia.
Published The Mediterranean Diet: Good for your health and your hip pocket (via sciencedaily.com) Original source
We've heard it time and time again -- the Mediterranean diet is great for our health. But despite the significant health benefits of this eating plan, a common deterrent is often the expected costs, especially when budgets are tight.
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 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 Diet high in fruit and vegetables linked to lower miscarriage risk (via sciencedaily.com) Original source
A preconception and early-pregnancy diet that contains lots of fruit, vegetables, seafood, dairy, eggs and grain may be associated with reducing risk of miscarriage, a new review of research suggests.
Published Could a vitamin deficiency cause 'double-jointedness' and hypermobile Ehlers-Danlos syndrome? (via sciencedaily.com) Original source
New research identifies genetic cause for hypermobility and hypermobile Ehlers-Danlos syndrome, a novel discovery that may also, for the first time, allow medical professionals to diagnose and treat the connective tissue disorders.
