Researchers at the Center for Microbiology and Environmental Systems Science at the University of Vienna and the Hebrew University of Jerusalem have now detected these chemical residues in leafy vegetables for the first time. Although the concentrations were low, the evidence was clear, a finding that is also known for drug residues in plant-based foods. The study was published in the internationally renowned journal Frontiers in Environmental Science. The presence of drug residues in commercially sold fruit ...

Older Americans may be missing out on a wide range of programs and services that could help them meet their needs or assist their aging loved ones, a new poll suggests. The new findings from the National Poll on Healthy Aging, based at the University of Michigan, show most older adults don’t know about important public resources for older adults and their caregivers, either by name or general description. The poll asked more than 4,000 adults over age 50 about their awareness and use of Area Agencies on Aging (AAAs), State Health Insurance Assistance ...

Highlights: Dermatophytes are fungi that cause skin, hair and nail fungal infections. These infections often develop resistance to azoles, a common anti-fungal treatment. A new study suggests that adding common bone loss drugs to azoles can improve efficacy. In lab tests, combinations of these drugs worked against dermatophyte species and prevented resistance. Washington, D.C.—Human skin, hair and nails are all vulnerable to fungal infections. While these infections are usually not serious, they’re difficult to fully resolve and often recur after treatment—sometimes for years. They’re also often resistant to treatments, including a common class of antifungals ...

DARIEN, IL – A new study to be presented at the SLEEP 2024 annual meeting found that circadian misalignment, which is highly prevalent in adolescents, is linked with carbohydrate consumption and sedentary behavior in teens. Results show that a later sleep schedule was significantly associated with greater intake of carbohydrates, and this relationship was partially explained by irregular sleep timing. A later sleep schedule also was associated with greater sedentary behavior, even after adjusting for variables such as demographics, sleep disorders, and insufficient sleep. “Delaying sleep schedules is normal during puberty and adolescence; however, some ...

DARIEN, IL – A new study to be presented at the SLEEP 2024 annual meeting found that it is common for foster caregivers to give melatonin to their child, and these children who have taken melatonin have worse sleep and more daytime behavioral problems. Results show that 48% of foster caregivers reported administering melatonin to their child. Children given melatonin had poorer overall sleep quality compared to children not given melatonin, yet even after adjustment for sleep quality and other potential confounders, melatonin use was associated with increased severity of daytime behavioral problems in foster ...

Bronze cauldrons were used by the inhabitants of the Mongolian steppe around 2,700 years ago to process animal blood and milk. This is shown by a protein analysis of archaeological finds from this period. Scattered across the Eurasian steppe, archaeologists repeatedly come across metal cauldrons from the Bronze Age during excavations. However, it was previously unclear exactly what they were used for. Now, an international study led by researchers at the University of Basel and published in the journal Scientific Reports reveals their secret: Mongolian nomads collected blood ...

Scientists have discovered genetic clues to the cause of restless leg syndrome, a condition common among older adults. The discovery could help identify those individuals at greatest risk of the condition and point to potential ways to treat it. Restless leg syndrome can cause an unpleasant crawling sensation in the legs and an overwhelming urge to move them. Some people experience the symptoms only occasionally, while others get symptoms every day. Symptoms are usually worse in the evening or at night-time and can severely impair sleep. Despite the condition ...

Scientists have detected what they believe to be a neutron star spinning at an unprecedentedly slow rate —slower than any of the more than 3,000 radio emitting neutron stars measured to date. Neutron stars - the ultra-dense remains of a dead star - typically rotate at mind-bendingly fast speeds, taking just seconds or even a fraction of a second to fully spin on their axis. However, the neutron star, newly discovered by an international team of astronomers, defies this rule, emitting radio signals on a comparatively ...

Even widespread species could be genomically vulnerable to the climate crisis, scientists warn. By studying the DNA of puddle frogs living in central African rainforests, the scientists found that areas of high environmental variation foster high genetic variation. If these varied habitats and the frogs that live there are lost, genetic variants that could have allowed the species to evolve to survive the climate crisis could be lost too. Meanwhile, populations with low genetic variation could become extinct quickly, unable to adapt. “Generally, the more genomic variation within ...

More than 3.4 million people in the US and 65 million people worldwide have epilepsy, a neurological disorder that affects the nervous system and causes seizures. One in 26 people will develop epilepsy at some point in their lives, and 1 out of 1000 people with epilepsy die from unexpected deaths each year. Like many conditions, epilepsy treatment starts with early detection. The World Health Organization estimates that 70% of people with epilepsy could live seizure-free if adequately diagnosed and treated. Over the years, ...

Niigata, Japan - Human society includes various minority groups. However, it is often difficult to know whether someone is a minority member simply by looking at the person, as minority traits may not be visually apparent (e.g., sexual orientation, color vision deficiency). In addition, minorities may hide their minority traits or identities. Consequently, we may have been unaware of the presence of minorities in daily life. Probabilistic thinking is critical in such uncertain situations. The people with whom we interact in our daily lives are typically a group of several dozen individuals (e.g., a school class). How do we judge the probability of including at least one minority ...
