Fiber is something that most of us get far too little of. To change that, we need to actually enjoy eating it. Food researchers from the University of Copenhagen have now invented a "disguise" that solves the problem of the dry and gritty mouth feel of fibers. Think of how it would be to drink a juice with wheat bran in it – you may imagine an unpleasant gritty sensation which would make you less prone to enjoy it. Unfortunately, this feeling is often associated with insoluble dietary fibers. ...

Antibacterial drugs are important for treating infections. But increasingly, bacterial resistance to current drugs — so they don’t work well, or even at all — means new ones are urgently needed. Building on previous work, researchers in ACS Infectious Diseases have demonstrated a potential antibacterial treatment from a modified darobactin, a compound originally from a bacterium. The team reports proof-of-concept animal trials on infections caused by bacteria, including E. coli, that are known to develop drug resistance. This study was published during the World Health Organization’s World Antimicrobial Resistance (AMR) Awareness ...

Residential garden produce grown near the Fayetteville Works fluorochemical plant can expose those who consume it to per- and polyfluoroalkyl substances (PFAS), according to a new study conducted by researchers from North Carolina State University, East Carolina University and the Colorado School of Mines. “It is often assumed that contaminated drinking water is the main pathway through which we are exposed to PFAS,” says Detlef Knappe, professor of civil, construction, and environmental engineering at NC State and a lead investigator of the study. “An important goal of our study was to determine whether people ...

With most donated clothes exported or thrown away, experts are calling for a shakeup of how we deal with the growing fashion waste issue. A first of its kind study, published in Nature Cities, analysed what happens to clothes and other textiles after consumers no longer want them in Amsterdam, Austin, Berlin, Geneva, Luxembourg, Manchester, Melbourne, Oslo and Toronto. Across most western cities from Melbourne to Manchester it found the same pattern of textile waste being exported, going to landfill or being dumped in the environment. Global textiles waste each year weighs 92 million tonnes and this could double by 2030. Charity shops handle a large amount of used clothes, but the study ...

The human skin is home to a wide variety of bacteria. The composition of the community of bacteria—called the “skin microbiota”—has serious implications for skin health. A healthy balance between different species of bacteria on the skin often translates to healthy skin. The loss of this balanced skin microbiota can lead to diseases such as atopic dermatitis, acne, and psoriasis. Since the skin microbiota can vary based on various factors such as age, sex, climate, and an individual’s ...

As populations age, the prevalence of sarcopenia—a progressive loss of muscle mass and function—has become an increasingly urgent public health concern. Sarcopenia increases the risk of falls and frailty, reduces the quality of life for older adults, and heightens the likelihood of requiring long-term care. Preventing sarcopenia is, therefore, crucial for alleviating this healthcare burden.   A pioneering study conducted by researchers from Juntendo University in Japan sheds light ...

An enzyme called EZH2 has an unexpected role in driving aggressive tumor growth in treatment-resistant prostate cancers, according to a new study by scientists at Weill Cornell Medicine. The results could potentially lead to new therapies for patients with limited options and add to the significant progress the teams have made in understanding how advanced prostate cancer develops resistance to treatments that target androgen receptors. Prostate cancer is a leading cause of cancer-related death in men, claiming over 30,000 lives annually in the United States. While most prostate cancers initially respond ...

The study, led by researchers of the National Institute for Astrophysics (INAF), analyses a sample of 21 quasars, among the most distant ever discovered, observed in the X-rays band by the XMM-Newton and Chandra space telescopes. The results suggest that the supermassive black holes ...

Are student-teacher relationships critical to early childhood education? With roughly 33 million students enrolled in public elementary school education throughout the United States, (National Center for Education Statistics, 2022), there is an acute need to more comprehensively understand the ways in which children’s development can be promoted through student-teacher relationships.   In a new Child Development study, researchers at The Ohio State University and University of Pennsylvania explored the significance of student-teacher relationships between kindergarten and third grade. Using the Early Childhood ...

After the June 2022 US Supreme Court ruling that allowed states to ban abortion, women of childbearing age in states where abortion became illegal reported increased rates of anxiety. That’s according to a new study published in Contemporary Economic Policy. The study relied on data from the Household Pulse Survey, a monthly online survey by the United States Census Bureau in collaboration with other federal agencies that gathers a vast array of data on representative samples of American adults from all 50 states and the District of Columbia. Investigators analyzed information on ...

In a study published in Ecological Entomology, a journal from the Royal Entomological Society, researchers assessed whether a shortage of natural meadows in urban spaces for pollinating insects might be addressed by creating meadows where wildflowers are planted or sown among grasses. The research, which was conducted in Warsaw, Poland, showed no difference in the composition of insect-pollinated plants between these two meadow types. There was also no difference between the meadow types concerning the species richness of butterflies, bees, and hoverflies. The number of butterflies ...

Hypoxic-ischemic encephalopathy (HIE) is one of the leading causes of newborn mortality and morbidity worldwide, and lowering the baby’s body temperature—called therapeutic hypothermia—is often used as a treatment. A review in Developmental Medicine and Child Neurology highlights additional therapies for HIE that are being tested with and without concomitant therapeutic hypothermia. Neonatal HIE is characterized by neurological dysfunction resulting from inadequate oxygen and blood flow to the brain near the time of birth. Therapeutic hypothermia is an established therapy in ...

New research in FEBS Open Bio reveals insights into the venom of two of the most venomous fish species on earth: the estuarine stonefish (Synanceia horrida) and the reef stonefish (Synanceia verrucosa), which are typically found in the warm and shallow regions of the Indo-Pacific region, the Persian Gulf, and the Red Sea. Through multiple analytical techniques, investigators discovered the presence of three neurotransmitters new to stonefish venom, namely gamma-aminobutyric acid (GABA), choline, and 0-acetylcholine. Although these molecules ...

Through a 20-year experiment, investigators have shown how different trees adjust their strategies for acquiring nutrients through their roots as soil warms with climate change. The research, which is published in Global Change Biology, included trees that associate with different fungi that help roots absorb nutrients. Measurements showed that when exposed to warmer soils, oak trees associated with ectomycorrhizal fungi reduce interactions with soil microbes while increasing fine root exploration, whereas maple trees that associate with arbuscular mycorrhizal largely maintain ...

Research published in the Journal of the American Geriatrics Society has identified several community-level factors that may increase people’s risk of experiencing cognitive impairment. In the study of 2,830 dementia-free US individuals aged 65+ years, 23.2% of participants were categorized as having mild cognitive impairment. People who lived in areas with higher neighborhood disadvantage, higher air pollution, higher homicide rate, and less greenspace had elevated odds of having mild cognitive impairment. Completing schooling in a Southern US state was also associated with a greater likelihood of ...

A stay in space exerts extreme pressures on the human body. Astronauts’ bodies and brains are impacted by radiation, altered gravity, challenging working conditions, and sleep loss – all of which could compromise cognitive functioning. At the same time, they are required to perform complex tasks, and minor mistakes can have devastating consequences. Little is known, however, about whether astronauts’ cognitive performance changes while in space. Now, working with 25 astronauts who spent an average of six month on the International Space Station (ISS), researchers in the US have examined changes in a wide range of cognitive performance domains. ...

Larger pay increases and better benefits could help keep K-12 teachers in the teacher workforce, finds a new, nationally representative RAND survey.     U.S. teachers reported modest pay increases between the 2022-2023 and 2023-2024 school years, only $2,000 on average and well below their desired increase of $16,000. Black teachers and teachers in states where collective bargaining is prohibited reported they received the smallest pay increases.     “Teachers who received larger pay increases also said they were less likely to intend to leave the profession,” ...

Early development of an embryo is solely supported by maternally deposited RNAs and proteins until its own genome is activated through a process called zygotic genome activation (ZGA). Recent research by Chinese scientists has revealed novel molecular mechanisms by which HIRA acts in concert with dPCIF1 to establish a totipotent chromatin and facilitate orderly zygotic genome activation in the early embryos of Drosophila. Results of the study were published in PNAS on Nov. 14 as “HIRA and dPCIF1 coordinately establish totipotent chromatin and control orderly ZGA in Drosophila embryos.” The ...

Researchers have used artificial intelligence (AI) to analyse patient urine samples and predict when symptoms of chronic obstructive pulmonary disease (COPD) will flare up according to a study published today (Wednesday) in ERJ Open Research [1].   The patients taking part in the study carried out a simple daily dipstick test on their urine and sent their results to researchers using their mobile phones.   Using AI to analyse the results, researchers were able to ‘forecast’ a deterioration in symptoms one week in advance. ...
