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 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 One in five women become pregnant naturally after having a baby conceived with IVF (via sciencedaily.com) Original source
New research analyzed data from 11 studies of over 5,000 women around the world between 1980 and 2021, to evaluate how common it is to get pregnant naturally after having a baby conceived by fertility treatment. Around 20% of women who needed fertility treatment, such as IVF, to conceive their first child are likely to get pregnant naturally in the future, finds a new study.
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 New diagnostic finds intact sperm in infertile men (via sciencedaily.com) Original source
Researchers develop new diagnostic tool to visualize protein biomarkers of well-developed sperm to determine if surgical sperm extraction may be successful for certain infertile men.
Published Elimination of type of bacteria suggests treatment for endometriosis (via sciencedaily.com) Original source
A research group has discovered that using an antibiotic to target Fusobacterium, a common bacterium that causes inflammation, improved the symptoms of endometriosis. Their findings suggest an alternative treatment for the disease.
Published Researchers successfully induce primate oocytes in the lab (via sciencedaily.com) Original source
The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation of stem cells in the lab (in vitro). Of particular interest are oocytes, which are female germ cells that develop into eggs. Understanding their development could have far-ranging impacts, from infertility treatment to conservation of endangered species. A new study has successfully induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with humans. By establishing a culture method for inducing the differentiation of meiotic oocytes, the researchers aimed to shed light on germ cell development in both humans and other primates.
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 Happy worms have healthy eggs (via sciencedaily.com) Original source
Researchers have exposed roundworms (a well-established model organism in biological research) to selective serotonin reuptake inhibitors (SSRIs), a class of drugs used for treating depression and anxiety. Surprisingly, this treatment improved the quality of aging females' egg cells.
Published Scientists discover the dynamics of an 'extra' chromosome in fruit flies (via sciencedaily.com) Original source
Most chromosomes have been around for millions of years. Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans and is associated with treatment-resistant cancer and infertility. The findings may one day lead to developing more targeted therapies for treating these conditions.
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.
