Nearly 70% of US adults meet new definition of obesity, study finds

How is it that we all see the world in a similar way? Imagine sitting with a friend in a café, both of you looking at a phone screen displaying a dog running along the beach. Although each of our brains is a world unto itself, made up of billions of neurons with completely different connections and unique activity patterns, you would both describe it as: "A dog on the beach." How can two such different brains lead to the same perception of the world?

As your youth fades further into the past, you may start to fear growing older.

Medication has long been the cornerstone of treatment for people with epilepsy, but it doesn't stop seizures for everyone and may come with significant side effects. New options in use or under development include devices and gene and cell therapies aimed at resetting or rehabilitating the brain circuits that cause seizures, explains Dr. Jonathon Parker, a neurosurgeon at Mayo Clinic in Phoenix and director of the Device-Based Neuroelectronics Research Lab.

Around a third of autistic people—children and adults alike—are unable to share what they want using speech.

Everyone gets headaches. Everyone misplaces their phone or forgets a name now and then. Most of the time, these moments are harmless—the result of stress, fatigue, or just a busy mind. Yet they're also examples of symptoms that can, in rare cases, signal something far more serious: a brain tumor.

Delirium affects many hospitalized older Australians, and while it can have many complications, treatments are limited. However, researchers have identified intranasal insulin as a potential new treatment that leads to a faster recovery and reduced time spent in hospital.

New research has uncovered shared patterns between ribosomal RNAs and genes linked to brain disorders, including autism, bipolar disorder, ADHD, and schizophrenia.

During the COVID-19 pandemic, there was an unexpected increase in the number of cases of type 1 diabetes in Sweden, particularly among children under 5 and young adult men. The infection accelerated the onset of diabetes among children between the ages of 5 and 9.

We live in an age where clinical labels once confined to the DSM-5—the diagnostic manual for mental health professionals—now spill into everyday language.

Stem cells in most organisms typically take cues from adjacent cells. But new research from the Stowers Institute for Medical Research reveals planarian stem cells ignore their nearest neighbors and instead respond to signals farther away in the body. This discovery may help explain the flatworm's extraordinary ability to regenerate—and could offer clues for developing new ways to replace or repair tissues in humans.

Why are we able to recall only some of our past experiences? A new study led by Jun Nagai at the RIKEN Center for Brain Science in Japan has an answer. Surprisingly, it turns out that the brain cells responsible for stabilizing memories aren't neurons. Rather, they are astrocytes, a type of glial cell that is usually thought of as a role player in the game of learning and memory.

A research team has discovered that docosahexaenoic acid (DHA), a major omega-3 fatty acid found in fish oil, directly relaxes smooth muscle in the male reproductive tract by blocking specific calcium channels.

More than a third of Canadian teens say climate change is impacting their mental health, according to a national study led by Athabasca University researchers, published in PLOS Mental Health.

New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London and the social enterprise Breathe Arts Health Research has shown that a specially designed group singing intervention, Breathe Melodies for Mums, is an effective and acceptable way to treat mothers with postnatal depression.

A study carried out by a team of researchers from The Institute of Cancer Research, London, found that combining two types of genetic tests gives doctors a much better chance of identifying multiple myeloma patients who are at risk of early relapse.

A new study from Swansea University, U.K., using population-scale data, has revealed insights into how people use health and care services in their final year of life and highlights the need for better identification and support for people needing palliative care.

California, like much of the nation, is not producing enough nurses working at bedsides to meet the needs of an aging and diverse population, fueling a workforce crunch that risks endangering quality patient care. Nearly 60% of California counties, stretching between the borders with Mexico and Oregon, face a nursing shortage, according to state data.

Researchers at the Institute for Social Research, University of Michigan, report that more than one in five young adults in the US use cannabis or alcohol to help them fall asleep. Nearly half of those who use cannabis said they sometimes relied on it for sleep, suggesting a strong link between substance use and sleep regulation during young adulthood.
