The strongest permanent magnets today contain a mix of the elements neodymium and iron. However, neodymium on its own does not behave like any known magnet, confounding researchers for more than half a century. Physicists at Radboud University and Uppsala University have shown that neodymium behaves like a so-called 'self-induced spin glass,' meaning that it is composed of a rippled sea of many tiny whirling magnets circulating at different speeds and constantly evolving over time.

A font called Sans Forgetica was designed to enhance people's memory for information displayed in that font--compared to reading information in an ordinary font, such as Arial.
But scientists from the University of Warwick and the University of Waikato in New Zealand have discovered that Sans Forgetica does not enhance memory.
These scientists carried out four experiments comparing San Forgetica's alleged powers to those of ordinary fonts and found Sans Forgetica did not help.
Capable school graduates sometimes choose low-ranking universities which do not match their abilities. According to the findings of HSE University researchers, up to one-quarter of school graduates in Moscow enrol in low-quality universities despite scoring highly on their USE (Unified State Exam, the final school exam and a standard university admission mechanism in Russia). This academic mismatch limits their life opportunities and often stems from unequal starting conditions in the family and at school.
An international survey of Global Consortium on Climate and Health Education (GCCHE) membership found that the majority of members--health professions schools and programs, including medical, nursing, and public health--offer learning opportunities related to the health impacts of climate change, yet many also encountered challenges in instituting or developing curricula. The results of the survey provide a baseline assessment of the state of climate-health education internationally among health professions institutions.
For many patients with a bicuspid aortic valve that needs replacing, transcatheter aortic valve replacement (TAVR) appears to be a safe treatment option with low complication rates, according to a study published in JACC: Cardiovascular Interventions. The study found patients with bicuspid valves who were at increased risk for surgery had a 30-day and one-year mortality rate and stroke rate that was similar to patients with the more common tricuspid valves.
Yale researchers have found a neural home of the feeling of stress people experience, an insight that may help people deal with the debilitating sense of fear and anxiety that stress can evoke, Yale researchers report May 27 in the journal Nature Communications.
Brain scans of people exposed to highly stressful and troubling images -- such as a snarling dog, mutilated faces or filthy toilets -- reveal a network of neural connections emanating throughout the brain from the hippocampus, an area of the brain that helps regulate motivation, emotion and memory.
People who believe more strongly that depression is biologically caused also tend to think it is more severe and long lasting, compared to those who see less of a role for biological causes, a new Rutgers study finds.
At the same time, people who believe that biological factors cause depression also tend to be more optimistic that treatment will have a positive effect, said Sarah Mann, a former doctoral student at Rutgers University-New Brunswick who led the study.
United States has been facing a serious problem of drug abuse and addiction, and has seen around 700,000 deaths within a span of 20 years (1999 to 2017) due to drug overdose. Opioid abuse, among other drugs, has been a prime cause of deaths due to overdose and misuse. In order to control this opioid epidemic, Highmark Inc., a national health plan and the second largest integrated delivery and financing system in USA devised, implemented and assessed a series of quality management-focused opioid interventions with the help of a three-pronged public health strategy.
Young people, men and people in "individualistic" societies report higher levels of loneliness, according to a large-scale global study.
The study - based on responses from more than 46,000 participants around the world - is the first published research to come from the BBC Loneliness Experiment.
The ages of participants ranged from 16-99, and the results show a steady decrease in loneliness as people age.
Giving beneficial bacteria to stressed mothers during the equivalent of the third trimester of pregnancy prevents an autism-like disorder in their offspring, according to a new animal study by University of Colorado Boulder researchers.
The study, published in the journal Brain, Behavior, and Immunity, marks the latest in a series of studies in animals and humans suggesting that exposure to certain immune-modulating microbes can dampen inflammation, positively impacting the brain and central nervous system.
VANCOUVER, Wash. - Some of the most common mental disorders, including depression, anxiety and PTSD, might not be disorders at all, according to a recent paper by Washington State University biological anthropologists.
Patients with heart failure who experience low health literacy are at an increased risk of hospitalization and mortality. This finding has significant clinical and public health implications and suggests that assessing and intervening upon an individual's understanding of their own health could improve heart failure outcomes, according to research published in JACC: Heart Failure.
A team of researchers from the University of Southampton, the University of Bath and King's College London, have provided compelling evidence of the impact of adversity in childhood on neuropsychological functioning in adulthood. They also showed that neuropsychological difficulties may explain why early adversity is linked to attention deficit hyperactivity disorder (ADHD) in later life.
Nearly half of parents of children under age 18 say their stress levels related to the coronavirus pandemic are high, with managing their kids' online learning a significant source of stress for many, according to a new survey by the American Psychological Association.
As the global pandemic continues and parents juggle child care, work and schooling demands, the mental health toll on parents is growing, warns APA. At the same time, the proportion of Americans saying that the economy or work is a significant source of stress in their life has risen significantly.
