The use of thyroid hormones other than the commonly prescribed hormone medicine levothyroxine to treat hypothyroidism, or underactive thyroid, is increasing, according to a study being presented Friday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago, Ill. “This is significant because the long-term health outcomes of these treatments are not as well known as levothyroxine,” said researcher Matthew Ettleson, M.D., of the University of Chicago in Chicago, Ill. The thyroid makes the hormones triiodothyronine ...

CHICAGO—The percent of metabolic associated fatty liver disease (MAFLD), the leading global cause of liver disease, is increasing in U.S. adults, according to a study presented Friday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago, Ill. Mexican Americans consistently had the highest percentage of MAFLD, especially in 2018, although the prevalence of increase was higher among Whites, the study found. MAFLD, previously known as non-alcoholic fatty liver disease (NAFLD), is fast becoming the most common indication ...

Everyone has 24 hours per day. Across the global population of 8 billion people this adds up to approximately 190 billion human hours per day. How those hours are spent determines the impacts we have on our surroundings as well as how we experience life. To find out how people around the world use their time, a research team led by McGill University has gathered and analyzed information about both economic and non-economic activities in order to estimate, for the first time, what a day in the life of the world looks like. “At present, we are struggling to come to terms with global challenges, and that calls for fresh perspectives on how the world ...

The European Commission's stated aim is to improve access to innovative drugs at the national level throughout the EU. Firstly, according to the proposal for the reform of EU pharmaceutical legislation, there are still considerable differences in access between countries. Secondly, drug development has so far only been geared to a limited extent to the actual needs of patients. According to the German Institute for Quality and Efficiency in Health Care (IQWiG), the latter point is in line with the perspective of the ...

Findings highlight racial disparities in sudden unexpected infant death in the U.S.  Only 16% fathers followed all three AAP-recommended infant sleep practices Rates of breastfeeding initiation and breastfeeding at eight weeks were much higher among fathers who wanted their infant’s mother to breastfeed than those who did not or had no opinion CHICAGO --- Fathers can make a huge difference in whether an infant is breastfed and placed to sleep safely, according to a recent survey of new fathers led by scientists at Northwestern University and the Ann & Robert H. Lurie Children’s Hospital of Chicago.  The study included 250 fathers who ...

In an article published yesterday in the prestigious journal Science, leading researchers from the University of Waterloo, University of Toronto, Yale University and the University of Pennsylvania look at how AI (large language models or LLMs in particular) could change the nature of their work. “What we wanted to explore in this article is how social science research practices can be adapted, even reinvented, to harness the power of AI,” said Igor Grossmann, professor of psychology at Waterloo.  Grossmann and colleagues note ...

‘Weed early and often’ is the key to a productive garden. Interestingly, certain species of ants are also avid gardeners, a practice they’ve refined over 50 million years. They too weed their underground fungus gardens, but how they know what to weed out has been a mystery. Now, a multidisciplinary team of scientists report in PNAS on June 15 how ants distinguish the good fungus from the bad. People rely on sight to identify weeds but ants grow fungus underground in the dark and must have other ways to sense undesirable garden denizens. A team led by Jonathan Klassen, Ph.D., at the ...

Biological treatment processes are critical for sewage purification, wherein microbial interactions are tightly associated with treatment performance. Previous studies have focused on assessing how environmental factors (such as salinity) affect the diversity and composition of the microbial community but ignore the connections among microorganisms. To fill this gap, an international team of researchers conducted an in-depth analysis of microbial interactions at elevated salinity in activated sludge systems. Biological ...

A chemical linked to a higher risk of leukemia and other blood cell cancers creeps into millions of homes whenever residents light their gas stoves. A new Stanford-led analysis finds that a single gas cooktop burner on high or a gas oven set to 350 degrees Fahrenheit can raise indoor levels of the carcinogen benzene above those in secondhand tobacco smoke. Benzene also drifts throughout a home and lingers for hours in home air, according to the paper published June 22 in Environmental Science & ...

Leaf arrangements in the earliest plants differ from most modern plants, overturning a long-held theory regarding the origins of a famous mathematical pattern found in nature, research shows. The findings indicate that the arrangement of leaves into distinctive spirals, that are common in nature today, were not common in the most ancient land plants that first populated the earth’s surface. Instead, the ancient plants were found to have another type of spiral. This negates a long held theory about the evolution of plant leaf spirals, indicating that they evolved ...

About The Study: The findings of this qualitative study suggest that institutional plans to protect frontline clinicians from the responsibility for allocating scarce resources may be unworkable, especially in a state of chronic crisis. Efforts are needed to directly integrate frontline clinicians into institutional emergency responses and support them in ways that reflect the complex and dynamic realities of health care resource limitation.  Authors: Catherine R. Butler, M.D., M.A., of the University of Washington in Seattle, ...

A new study by an international team from Africa, Asia and Europe has put forward three criteria for evaluating the success of migration as adaptation in the face of climate change: well-being, equity and sustainability. The study shows that while migration is increasingly recognised as an effective way to deal with climate risks, or a form of adaptation, it is far from a silver-bullet solution. For example, remittances – which include flows of money, ideas, skills and goods between migrants and their places of origin – are thought to be key to facilitating adaptation to climate change. But, drawing on evidence from every continent ...

A collaborative team led by researchers from City University of Hong Kong (CityU) recently invented an innovative method for synthesizing high-quality, semiconducting nanomesh at a lower temperature and production cost than conventional methods. The findings will help enable the large-scale production of nanomesh for next-generation electronics. Nanomesh is a nano-scale material formed from a network of nanowires. For several decades, one-dimensional materials like nanowires made of crystalline inorganic materials have been widely explored as the main driver for emerging electronics, as they have features like mechanical flexibility, ...

A new weevil species was discovered in Japan’s pristine subtropical forests on Ishigaki Island and Yanbaru National Park in Okinawa. Renowned for their remarkable biodiversity, the Ryukyu Islands are a chain of subtropical islands distributed between mainland Japan and Taiwan that boast a relatively isolated evolutionary history, and are home to a distinctive and fascinating insect fauna.   Researchers at the Okinawan Institute of Science and Technology (OIST) have been placing net traps to monitor insects on Okinawa ...

A human cell harbors roughly 2 meters of DNA, encompassing the essential genetic information of an individual. If one were to unwind and stretch out all the DNA contained within a single person, it would span a staggering distance – enough to reach the sun and back 60 times over. In order to manage such an astounding volume of biological information, the cell compacts its DNA into tightly packed chromosomes. “Imagine DNA as a piece of paper upon which all our genetic information is written.” Says Minke A.D. Nijenhuis, co-corresponding author. “The paper is folded into a very tight structure in order to fit all of that ...

Recently, Providencia spp. which have been detected in patients with gastroenteritis, and similar to enterohemorrhagic Escherichia coli. O157 and Salmonella spp., have been attracting attention as causative agents of food poisoning. For children with low immunity, food poisoning can be lethal as it causes severe symptoms such as diarrhea and dehydration, so clarifying the source of infection and pathogenic factors of Providencia spp., and establishing preventive methods are urgent issues worldwide. A joint research group led by Professor Shinji Yamasaki, Dr. Sharda Prasad Awasthi, a Specially Appointed Lecturer, and graduate ...

Staying up late at night has little impact on how long ‘night owls’ live, according to new research published in the peer-reviewed journal Chronobiology International. Data based on nearly 23,000 twins, however shows that evening types have a slightly increased risk of dying than morning types, but this is largely linked to smoking and drinking. The study which tracked people over the course of more than 37 years in Finland suggests that lifestyle should be considered. This is when analyzing the impact on health of chronotype – the body’s natural inclination to sleep at a certain time. “Our ...
