Iceland’s ongoing volcanic eruptions may continue on and off for years to decades, threatening the country’s most densely populated region and vital infrastructure, researchers predict from local earthquake and geochemical data.   The eruptions on the Reykjanes Peninsula have forced authorities to declare a state of emergency, with a series of eight eruptions having occurred since 2021. This southwestern region is home to 70 percent of the country’s population, its only international airport, and several geothermal power plants that supply ...

A new Child Development study by researchers at the University of Maryland, Furman University, Education Northwest and University of Hawaiʻi at Manoa in the United States, examined whether children think it’s unfair for a teacher to select students from only one gender or ethnic group for leadership duties.  Researchers learned that children and adolescents are not only aware of these situations, but they are also motivated to rectify these types of inequalities in the classroom. Understanding ...

Research suggests that phone use may have an effect on children’s speech input and language development. However, most of the prior work in this area examines parents and children in controlled laboratory experiments in public spaces and may not be representative of daily interactions between a child and their caregivers.  New research in Child Development by the University of Texas at Austin in the United States is the first to combine objective markers of speech (via audio recorders worn by infants) and maternal cell phone use from cell phone logs. This research helps document ...

For decades, it’s been thought that people with heart failure should drastically reduce their dietary salt intake, but some studies have suggested that salt restriction could be harmful for these patients. A recent review in the European Journal of Clinical Investigation that assessed all relevant studies published between 2000 and 2023 has concluded that there is no proven clinical benefit to this strategy for patients with heart failure. Most relevant randomized trials were small, and a single large, ...

Research published in Terra Nova provides insights into the ongoing eruption series on the Reykjanes Peninsula in Iceland that began in 2021. The eruptions forced the evacuation of an entire town, with an uncertain future about the possibility for residents to return. For the study, investigators analyzed information from local earthquakes and geochemical data on lava samples erupted through time. The combined evidence implies that the lavas that have erupted in recent years were derived from a moderately-sized magma reservoir ...

A new study that looked for relationships between early social media use and depression across adolescence and into young adulthood found that certain factors may make social media more risky or protective regarding depression. The findings, which are published in the Journal of Adolescence, suggest that social media use does not impact all adolescents in the same way, and an individualized approach is needed to determine the benefits and harms of social media on young people’s mental health. For the study, 488 adolescents living in the United States were surveyed once a year for 8 years ...

Based on focus groups with children and young people with peanut allergy, experts have published guidance for clinicians working in the UK’s National Health Service (NHS) to help them safely and equitably implement Palforzia® peanut oral immunotherapy. Their recommendations are published in Clinical & Experimental Allergy. In 2022, the National Institute for Health and Care Excellence in the UK recommended the use of Palforzia®—which has defatted peanut powder as its active ingredient—for desensitizing children ...

Worldwide, introduced non-native herbivores have the potential to threaten native ecosystems. For example, in western North America, uncontrolled numbers of feral horses and burros are threatening natural habitats and the native wildlife that rely on them. New research published in the wildlife research journal Wildlife Monographs documents the impact that non-native burros are having on plant and animal life in the Sonoran Desert of North America. Investigators found that the presence of burros was associated with changes to long-lived plants important to the region. In areas with established burro herds, researchers documented lower ground cover, plant density, and foliage density, ...

Ambient temperatures are associated with over 5 million premature deaths worldwide every year, more than 300,000 of which in Western Europe alone. In a context of rapidly warming temperatures that successively broke previous records during the last two decades, it is essential to use epidemiological models to develop novel, impact-based early warning systems predicting the health effects of forecast temperatures. This is precisely what the Adaptation group at the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has done: Forecaster.health is the first pan-European, open-access platform using sex- and age-specific epidemiological ...

As critical pollinators, bees keep our agricultural systems going — but human-caused changes to the planet heavily impact their foraging options. To help protect our food security, we need more information about bees’ own dietary requirements. Scientists writing in Frontiers in Sustainable Food Systems studied the nutritional value of 57 types of pollen and found that bees need to forage from a variety of plants to balance their diet between fatty acids and essential amino acids. “Despite public interest and a rise in pollinator plantings, little is known ...

Even though there is substantial variability in the contents and nutritional profiles of plant-based meat alternatives (PBMAs), the nutritional profiles tend to reflect a heart-healthy dietary pattern. A review article appearing in the Canadian Journal of Cardiology, published by Elsevier, of the available studies directly comparing the impact of plant-based and animal-based meats consistently suggests that the plant-based alternatives improve cardiovascular risk factors. PBMAs are highly processed plant-based food products that typically replace meat in the diet. ...

SINGAPORE — Scientists have generated a comprehensive map of the gene targets regulated by the transcription factors HNF4A and HNF1A in human pancreatic beta cells and liver cells. Published in the journal Nature Communications, the study revealed common and tissue-specific molecular pathways regulated by HNF4A and HNF1A, two proteins that possess important functions governing the development and function of the pancreas and liver. Notably, the scientists identified several novel gene targets in pancreatic beta cells, the cells responsible for insulin ...

More than 100,000 oil and gas wells across the western U.S. are in areas burned by wildfires in recent decades, a new study has found, and some 3 million people live next to wells that in the future could be in the path of fires worsened by climate change.  Researchers from the University of California, Berkeley, said their analysis, which was published last week in the journal One Earth, is the first to examine historical and projected wildfire threats on oil and gas facilities in the U.S. While the public health effects of scorched and damaged drill sites are unclear, researchers said the study is a necessary step ...

DALLAS, JUNE 25, 2024 — Cardiovascular disease is the leading cause of death for women, and gaps in care and access persist between women and men. Addressing those gaps could lead to an increase of at least 1.6 million years of quality life and boost the U.S. economy by $28 billion annually by 2040, according to a new report published today by the American Heart Association and the McKinsey Health Institute (MHI). To help close these gaps and foster gender specific cardiovascular disease science into implementation, the Association, observing 100 years of lifesaving service as the world’s leading nonprofit organization ...

(Santa Barbara, Calif.) — Computers have come so far in terms of their power and potential, rivaling and even eclipsing human brains in their ability to store and crunch data, make predictions and communicate. But there is one domain where human brains continue to dominate: energy efficiency. “The most efficient computers are still approximately four orders of magnitude — that’s 10,000 times — higher in energy requirements compared to the human brain for specific tasks such as image processing and recognition, although they outperform the brain in tasks like mathematical calculations,” said UC Santa Barbara ...

Biogenic monoamines — molecules like dopamine and serotonin — are famous for their role as the brain’s emissaries of mood, learning and memory, stress mechanisms, and fight-or-flight responses in the body. But these neurotransmitters existed in nature long before brains popped up in the evolutionary tree. They’re prevalent in plants, bacteria, and single-cell organisms as well, but their functions there are far less understood. Scientists at the Morgridge Institute for Research have added another task for ...

DURHAM, N.C. -- There’s a strong chance that last week’s scorching temperatures were even hotter than reported for those living in underserved urban areas. It’s been well established that more impoverished areas within cities are typically hotter than their wealthier neighborhoods. Dubbed “urban heat islands,” these communities have more buildings, less vegetation and somewhat higher population density, which combine to produce the heating effect. New research from environmental engineers at Duke University has shown that citizen science tools used to gauge heat in these ...

A functional, healthy bladder is something that many of us take for granted. Yet millions of Americans deal with bladder issues, ranging from temporary inconveniences to long-lasting conditions. While many bladder disorders can be managed with non-invasive solutions, some conditions may require surgery to restore bladder function. In patients with major bladder issues, a cystectomy may need to be performed. In this procedure, some or all of the bladder is removed (reasons for this may include acute trauma or bladder cancer). Sometimes, to compensate for the loss of tissue, the bladder is augmented (made larger), typically with ...

Vanderbilt University Medical Center (VUMC) researchers are touting data from a multicenter, international phase 2 clinical trial showing a new, curative treatment for sickle cell disease (SCD). The therapy, nonmyeloablative haploidentical bone marrow transplant (BMT) with thiotepa and posttransplant cyclophosphamide (PTCy), is proving to have equivalent efficacy and one-fifth the cost as recently FDA-approved myeloablative gene therapy options, according to Michael DeBaun, MD, MPH, director of the Vanderbilt-Meharry Center ...

In a significant finding, researchers from The Jackson Laboratory (JAX) and UConn Health have discovered that sodium valerate, a short-chain fatty acid produced by gut microbes, can dramatically reduce binge drinking behavior and blood ethanol concentration in mice. The study, reported June 17 in Microbiome, offers promising insights into the gut-brain axis and presents a novel therapeutic approach for excessive alcohol use. We are interested in physiological addiction genetics and genomics to identify new drug targets for treating addiction/overdose. The research team, led by Yanjiao Zhou, M.D., ...

Chocolate-flavored pills for children who hate taking medicine. Several drugs combined into one daily pill for seniors who have trouble remembering to take their medications. Drugs printed at your local pharmacy at personalized dosages that best suit your health needs. These are just a few potential advantages of 3D drug printing, a new system for manufacturing drugs and treatments on-site at pharmacies, health care facilities and other remote locations.  In 2015, the Food and Drug Administration approved the first 3D-printed drug, Spritam ...

Toronto - New research shows that CEOs who have moved away from their country of origin have a significantly higher tendency to make acquisitions internationally, with a preference for targets in their birth country or in countries that once colonized it. “Foreign-born CEOs are taking an increasing leadership role in the corporate world,” says researcher Ron Shalev, an associate professor of accounting at the University of Toronto Scarborough who is cross-appointed to U of T’s Rotman School of Management. “In our sample, 24 per ...

Shoppers browsing through blouses and blenders at Target know they can also quaff a cappuccino at one of more than 1,700 Starbucks cafeshoused within Targets. The strategic alliance benefits both corporations by helping them reach new markets, boost their brands, and add incremental sales. Collaborative partnerships such as this have grown at a pace of 3,600 per year, according to the SDC Platinum database. That’s partly because companies in alliances can gain access to new technologies and customers while keeping their autonomy. New research from Texas McCombs highlights ...
