Neuroblastoma is a cancer that affects the sympathetic nervous system of children. It is unusual among cancers because it shows a range of outcomes: from aggressive, potentially fatal progression to a unique phenomenon where the tumor spontaneously regresses even without treatment. Identifying why some patients regress and others don’t could help thousands of patients. A research group led by Nagoya University believes that the answer may lie in the “uncommitted” state of some neuroblastoma cells. In mice bred to have tumors that were presumed to regress, they discovered a population of “uncommitted" cells that ...

New study explores why foreign firms listed in the U.S. choose between IFRS and U.S. GAAP.

Bottom Line: The U.S. Preventive Services Task Force (USPSTF) recommends that clinicians screen for intimate partner violence in women of reproductive age, including those who are pregnant and postpartum. The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for caregiver abuse and neglect in older or vulnerable adults. Intimate partner violence affects millions of U.S. residents across the lifespan and is often unrecognized. Abuse of older or vulnerable adults by a caregiver or someone else they may trust is common and can result in ...

WASHINGTON, June 24, 2025 — When you think of solar panels, you usually picture giant cells mounted to face the sun. But what if “solar” cells could be charged using fluorescent lights? Perovskite solar cells (PeSCs) have emerged as a lower-cost, higher-efficiency alternative to traditional silicon solar cells due to their material structure and physical flexibility. Their large power conversion efficiency rate (PCE), which is the amount of energy created from the amount of energy hitting the cell, makes PeSCs well suited to converting lower light sources into energy. In APL Energy, by AIP Publishing, researchers from National Yang Ming Chiao Tung University in Taiwan ...

Using stem cells from patients with ALS (amyotrophic lateral sclerosis), Cedars-Sinai has created a lifelike model of the mysterious and fatal disease that could help identify a cause of the illness as well as effective treatments. In a study published in the peer-reviewed journal Cell Stem Cell, investigators detail how they created “ALS on a chip” and the clues the specialized laboratory chip has already produced about nongenetic causes of the disease, also known as Lou Gehrig’s disease. The work builds ...

Teens who see social media posts showing cannabis or e-cigarettes, including from friends and influencers, are more likely to later start using those substances or to report using them in the past month, according to surveys done by researchers at the Keck School of Medicine of USC. Viewing such posts was linked to cannabis use, as well as dual use of cannabis and e-cigarettes (vapes). Dual use refers to youth who have used both cannabis and e-cigarettes at some point. The results were just published in JAMA Network Open. The findings come amid a decline in youth e-cigarette use, reported in 2024 by the U.S. Food ...

Even the smartest machines can’t match young minds at language learning. Researchers share new findings on how children stay ahead of AI - and why it matters. If a human learned language at the same rate as ChatGPT, it would take them 92,000 years. While machines can crunch massive datasets at lightning speed, when it comes to acquiring natural language, children leave artificial intelligence in the dust. A newly published framework in Trends in Cognitive Sciences by Professor Caroline Rowland of the Max Planck Institute for Psycholinguistics, in collaboration with colleagues at the ESRC LuCiD Centre in the UK, presents a novel framework to explain how children ...

Tokyo, Japan – Mimicking the incredible skill of mother nature is never easy, especially when trying to match the remarkable chemical processes that take place in living organisms. Living systems, like cells, can carry out chemical reactions in very small spaces, sometimes involving single molecules. For many years, researchers have attempted to emulate this to allow for the manufacturing of specialized chemical compounds, but with limited success. However, new research published in the Journal of the American Chemical Society highlights the development of a new tool that assists with controlling chemical reactions. ...

A pretreatment step could help transplanted pancreatic islets survive longer in patients with type 1 diabetes, according to a new preclinical study from Weill Cornell Medicine investigators.

Cells depend on the precise reading of DNA sequences to function correctly. This process, known as gene expression, determines which genetic instructions are activated. When this fails, the wrong parts of the genome can be activated, leading to cancers and neurodevelopmental disorders. Scientists at the University of Geneva (UNIGE) have identified two proteins that play a key role in regulating this essential mechanism, paving the way for promising new treatments that could be more effective and less toxic than those currently available. Their findings are published in Nature Communications. Human DNA contains over 20,000 genes and would stretch nearly two metres ...

For decades, researchers have pursued lead-free alternatives to replace toxic yet high-performance lead-based antiferroelectrics (AFEs). Sodium niobate (NaNbO3, NN) emerged as a prime candidate due to its low cost and environmentally benign nature. However, its irreversible phase transition at room temperature, resulting in energy-wasting ferroelectric-like hysteresis, has hindered practical applications. The team published their work in Journal of Advanced Ceramics on June 18, 2025. Now, a materials scientists team has cracked this challenge through ions co-doping strategic. As published in Journal of Advanced Ceramics, co-doping NN with variable-valence elements Sn and Ce ...
