Published Speaking without vocal cords, thanks to a new AI-assisted wearable device (via sciencedaily.com) Original source
Bioengineers have invented a thin, flexible device that adheres to the neck and translates the muscle movements of the larynx into audible speech. The device is trained through machine learning to recognize which muscle movements correspond to which words. The self-powered technology could serve as a non-invasive tool for people who have lost the ability to speak due to vocal cord problems.
Published Fatty food before surgery may impair memory in old, young adults (via sciencedaily.com) Original source
Eating fatty food in the days leading up to surgery may prompt a heightened inflammatory response in the brain that interferes for weeks with memory-related cognitive function in older adults -- and, new research in animals suggests, even in young adults.
Published Gut bacteria make neurotransmitters to shape the newborn immune system (via sciencedaily.com) Original source
Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.
Published Infections from these bacteria are on the rise: New blood test cuts diagnosis time from months to hours (via sciencedaily.com) Original source
Researchers have designed a platform to perform blood-based diagnoses of nontuberculosis mycobacteria, simplifying and shortening a long-complicated procedure from 6 months to 2 hours. Rapid, accurate diagnosis has never been more important as cases of NTM infections have continued to increase annually, spreading from subtropical regions to more temperate zones in part due to global climate change.
Published FRYL gene variants linked to a new neurological disorder (via sciencedaily.com) Original source
A recent study links the FRYL gene to a new neurodevelopmental disorder in humans. They used fruit flies to establish that the loss of a functional copy of the FRY-like transcription coactivator (FRYL) gene is the underlying cause of this new disorder in fourteen individuals.
Published Age and sex associated with patient's likelihood of antimicrobial resistance (via sciencedaily.com) Original source
A person's age, sex and location are correlated with the chance that they have a bloodstream infection that is resistant to antibiotics, according to a new study.
Published How fear unfolds inside our brains (via sciencedaily.com) Original source
The stress-induced mechanisms that cause our brain to produce feelings of fear in the absence of threats -- such as in PTSD -- have been mostly a mystery. Now, neurobiologists have identified the changes in brain biochemistry and mapped the neural circuitry that cause generalized fear experiences.
Published How home food availability affects young children's nutrient intake (via sciencedaily.com) Original source
Early childhood is an important time for learning about nutrition and establishing healthy eating behaviors. Young children rely on parents to provide food options, and the availability of food in the home affects their dietary choices. A new study looks at changes in home food availability and nutrient intake for children from 2 to 4 years old.
Published Small amounts of licorice raise blood pressure, study finds (via sciencedaily.com) Original source
It is known that large amounts of licorice cause high blood pressure. A new study now shows that even small amounts of licorice raise blood pressure. The individuals who react most strongly also show signs of strain on the heart.
Published Gut bacteria important for overcoming milk allergy (via sciencedaily.com) Original source
Researchers have discovered a link between gut bacteria and the success of milk-allergy oral immunotherapy. The study found that Bifidobacterium -- a genus of beneficial bacteria in the gut -- was associated with a higher chance of successful treatment. The finding may help in the development of more effective oral immunotherapies, perhaps by combining them with probiotic supplements.
Published It's hearty, it's meaty, it's mold (via sciencedaily.com) Original source
Scientists are exploring how tuning the genomes of mushrooms and molds can transform these food sources into gourmet, nutrient-packed meals made with minimal processing and a light environmental footprint.
Published Common viruses trigger most cases of intussusception in children (via sciencedaily.com) Original source
Viral infections trigger more cases of intussusception, the common cause of bowel blockages in young children, than previously thought, according to a new study.
Published A healthier diet is linked with a slower pace of aging, reduced dementia risk, study shows (via sciencedaily.com) Original source
A healthier diet is associated with a reduced dementia risk and slower pace of aging, according to a new study. The findings show that a diet-dementia association was at least partially facilitated by multi-system processes of aging. Until now, the biological mechanism of this protection was not well understood.
Published New discovery reveals how the egg controls sperm entry (via sciencedaily.com) Original source
After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo, a new study finds. The work also explains how mutations in egg coat proteins can cause female infertility and may eventually lead to new contraceptive methods.
Published Blast-related concussions linked to higher Alzheimer's risk (via sciencedaily.com) Original source
U.S. veterans of the wars in Afghanistan and Iraq who suffered mild traumatic brain injury from exposure to explosive blasts were found to have changes in cerebrospinal fluid proteins that are typically seen in people who develop Alzheimer's disease, according to researchers.
Published Lives could be saved from tropical disease with new rapid test (via sciencedaily.com) Original source
A new test diagnoses patients with melioidosis within hours, rather than days, meaning they can receive the correct antibiotics faster.
Published Revolutionary chronic wound treatment could help millions (via sciencedaily.com) Original source
An effective treatment for chronic wounds that does not involve antibiotics, but an ionised gas to activate a wound dressing, has been developed by a team of international scientists.
Published What kinds of seismic signals did Swifties send at LA concert? (via sciencedaily.com) Original source
Seattle may have experienced its own Swift Quake last July, but at an August 2023 concert Taylor Swift's fans in Los Angeles gave scientists a lot of shaking to ponder. After some debate, a research team concluded that it was likely the dancing and jumping motions of the audience at SoFi Stadium -- not the musical beats or reverberations of the sound system -- that generated the concert's distinct harmonic tremors.
Published Tryptophan in diet, gut bacteria protect against E. coli infection (via sciencedaily.com) Original source
Gut bacteria and a diet rich in the amino acid tryptophan can play a protective role against pathogenic E. coli, which can cause severe stomach upset, cramps, fever, intestinal bleeding and renal failure.
Published Good news: The US maternal death rate is stable, not sky rocketing, as reported (via sciencedaily.com) Original source
A new study challenges the prevailing view on the maternal death rate in the United States. The findings show that the rates of maternal death were stable between 1999-2002 and 2018-2021, instead of the dramatic upward trends previously reported. Additionally, the study indicates that direct obstetric causes of death declined over the last 20 years.
