ANN ARBOR, Mich. –  Most parents agree that talking to their kids about puberty is important—but when and how to start the conversation is often less clear, a new national poll suggests. Among the most common challenges for parents: choosing the right age to start talking about body changes and whether to explain sex, according to the University of Michigan Health C.S. Mott Children’s Hospital National Poll on Children’s Health. Parents are evenly split in thinking it’s best to start talking about puberty before 10 years, at age 10 or when children are older. “It’s easy to assume a child is too ...

“Tusi”, also known as “tucibí” or “pink cocaine”, is a drug concoction that emerged in Latin America and Europe within the past decade and is becoming increasingly popular in the USA.  A new study published in the scientific journal Addiction estimates that in 2024, 2.7% of electronic dance music-nightclub attending adults in New York City (NYC) used Tusi in the past year, with higher use among Hispanic people and people who use other drugs.   Consumers often don’t understand what Tusi is when they take it.  Tusi ...

In popular culture, dads are stoic, sensitive and strong. So powerful is the mystique of the happy dad that celebrities, joke books – even hard seltzers – carry the label.   Real life is different. Fathers get down, sometimes debilitatingly. And as new research from Rutgers Health reveals, when paternal depression goes undiagnosed or unaddressed, the negative social and behavioral effects on children can persist for years.   In a study published in the American Journal of Preventive Medicine, Kristine Schmitz, an assistant professor of pediatrics ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have found that the motion of unlabeled cells can be used to tell whether they are cancerous or healthy. They observed malignant fibrosarcoma cells and healthy fibroblasts on a dish and found that tracking and analysis of their paths can be used to differentiate them with up to 94% accuracy. Beyond diagnosis, their technique may also shed light on cell motility related functions, like tissue healing.   While scientists and medical experts have been looking at cells under the microscope for many centuries, most studies and diagnoses focus on their shape, what they contain, and where different parts are located inside. ...

New research to be presented at this year’s European Congress on Obesity (ECO 2025, Malaga, Spain, 11-14 May) shows that the internationally recognised body mass index (BMI) cut-off points greatly overestimate overweight and obesity in male athletes. The study, from Italy, also proposes new cut-off points for overweight and obesity in this group. Body mass index (BMI) is a key method for measuring people’s weight status, defining whether they have normal weight, overweight or obesity. It is easily calculated by dividing an individual’s weight in kilograms by the ...

When you see a bag of carrots at the grocery store, does your mind go to potatoes and parsnips or buffalo wings and celery?  It depends, of course, on whether you’re making a hearty winter stew or getting ready to watch the Super Bowl.  Most scientists agree that categorizing an object — like thinking of a carrot as either a root vegetable or a party snack — is the job of the prefrontal cortex, the brain region responsible for reasoning and other high-level functions that make us smart and social. In that account, the eyes and visual regions of the brain are kind of like a security camera collecting data and processing it ...

LOGAN, UTAH, USA – Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies on many mutations with small and roughly equal effects, or is it driven by one or a few mutations that cause major changes in traits. Chromosomal rearrangements where large chunks of chromosomes are inverted, moved, deleted or duplicated, provide a possible source for such large-scale “macromutations.” However, characterizing chromosomal rearrangements with commonly tried ...

What were you investigating? We investigated how our brains process language during real-life conversations. Specifically, we wanted to understand which brain regions become active when we're speaking and listening, and how these patterns relate to the specific words and context of the conversation. What methods did you use? We employed artificial intelligence (AI) to take a closer look at how our brains handle the back-and-forth of real conversations. We combined advanced AI, specifically language models like ...

An international research collaboration led by Rutgers University-New Brunswick scientists that examined microscopic blobs of protein found in human cells has discovered that some morph from an almost honey-like substance to a hard candy-like solid.  These mysterious droplets, known as biomolecular condensates, solidify when they carry a high proportion of the protein alpha-synuclein, the scientists reported in Science Advances. Clumps of alpha-synuclein are commonly found in the brain cells of people with Parkinson’s disease, ...

Fifty years since its discovery, scientists have finally worked out how a molecular machine found in mitochondria, the ‘powerhouses’ of our cells, allows us to make the fuel we need from sugars, a process vital to all life on Earth. Scientists at the Medical Research Council (MRC) Mitochondrial Biology Unit, University of Cambridge, have worked out the structure of this machine and shown how it operates like the lock on a canal to transport pyruvate – a molecule generated in the body from the breakdown of sugars – into our mitochondria. Known as the ...

COLUMBUS, Ohio – Researchers have found that targeting an enzyme called PGM3 can help stop the growth of glioblastoma, the most dangerous type of brain tumor. This enzyme plays a vital role in the hexosamine synthesis pathway, which is involved in the processes of protein and lipid glycosylation that allow tumors to rapidly grow. Lipid glycosylation is a process where sugar molecules attach to fats (lipids) in the body. Researchers with The Ohio State University Comprehensive Cancer Center – Arthur G. James and Richard J. Solove Research Institute believe that targeting PGM3 can reduce tumor growth and eliminate glioblastoma cells. “This ...

In a groundbreaking study co-authored by a Texas A&M University scientist, researchers have revealed new insights into the geological history of Mars' Jezero Crater, the landing site of NASA’s Perseverance rover. Their findings suggest that the crater's floor is composed of a diverse array of iron-rich volcanic rocks, providing a window into the planet’s distant past and the closest chance yet to uncover signs of ancient life. Research scientist Dr. Michael Tice, who studies geobiology and sedimentary geology in the Texas A&M College of Arts and ...

PHILADELPHIA, PA (April 17, 2025) – A Monell Chemical Senses Center study published this week in the Journal of Clinical Investigation offers renewed hope for individuals living with Bardet-Biedl Syndrome (BBS), a rare genetic disorder characterized by early-onset obesity, compulsive eating, and cognitive impairments. The Monell team and colleagues identified that GLP-1 receptor agonists, a class of drugs currently used to treat type-2 diabetes and obesity, as a promising therapeutic for managing the metabolic complications associated with BBS. They used ...

PROVIDENCE, R.I. [Brown University] — For scientists who want to learn about the geological history of a planet, river deltas are a great place to start. Deltas gather sediment from a large area into one place, which can be studied to reveal climate and tectonic histories or signs of past life. That’s why NASA sent its most recent Mars rover to Jezero Crater, home to a prominent and well-preserved delta.  And that’s why planetary scientists are also interested in finding deltas on Saturn’s moon Titan. Titan is the only planetary body ...

UNIVERSITY PARK, Pa. — The professional world has no shortage of micromanagers — or, as Penn State School of Labor and Employment Relations (LER) faculty members Craig L. Pearce and Hee Man Park like to call them, “accidental dictators.” But leaders don’t have to fall into that trap, according to an article published in the journal Organizational Dynamics co-written by Pearce, Brova Family Endowed Professor of leadership and human resources, and Park, associate professor of human resource management and director of LER’s graduate program. The journal’s readership is largely made up ...

Just under 4 in 10 women who died by firearm suicide had no documented history of mental or physical health problems in a new study, highlighting a need for prevention strategies tailored to at-risk women. The findings come at a time when suicides have been on the rise, alongside a surge in gun ownership — especially among women, said lead author Laura Prater, an assistant professor in The Ohio State University College of Public Health. In the last two decades, firearm deaths in the U.S., including those involving suicide, increased by almost 50%. Women historically made up 10 to 20% of new gun owners, a percentage ...

People with medical debt in 2023 were about five times more likely to forgo mental health care treatment in the following year due to cost, compared to those without medical debt, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. For their study, the researchers analyzed 2023 and 2024 data from a nationwide survey related to mental health. The researchers found that 33.8% of respondents who reported having had medical debt in 2023 also reported forgoing mental health care for cost-related reasons in 2024, compared ...

Background and Aims Liver fibrosis is a key process in the progression of chronic liver diseases. However, there are currently no drugs specifically designed to treat liver fibrosis. Our Phase 2 trial of hydronidone for the treatment of chronic hepatitis B (CHB)-associated liver fibrosis showed that adding hydronidone to entecavir resulted in significant reversal of liver fibrosis. To further evaluate the efficacy of a 270 mg/day dose of hydronidone for treating liver fibrosis associated with CHB, we conducted ...

Both the use of next-generation sequencing (NGS) testing for cancer and the rate of claim denials for such testing increased between 2016 and 2021, despite implementation of a recent Medicare national coverage determination that established coverage standards for NGS testing. The analysis by Georgetown University researchers and colleagues, and funded by a grant from the National Cancer Institute at the National Institutes of Health, appears April 18, 2025, in JAMA Network Open. The researchers point to several possible ...

About The Study: In this serial cross-sectional study of adolescents in grades 7 to 11, legalization of cannabis edibles and extracts was associated with an increase not only in edible cannabis use and cannabis smoking, but also in the overall prevalence of cannabis use and co-use of alcohol and cannabis, highlighting the need for stricter policy measures to curb adolescents’ access to cannabis edibles and extracts and greater awareness among adolescents about harms of cannabis use. Corresponding ...

About The Study: In this survey study, more than 1 in 7 adults reported carrying medical debt in 2023, of whom 1 in 3 forwent mental health care in the subsequent year. Medical debt may exacerbate the treatment gap by potentially (1) raising the threshold for seeking care, (2) eroding patient trust in the health system, or (3) being denied care due to outstanding debts.
