Scientists have created a complete map showing how hundreds of possible mutations in a key cancer gene influence tumour growth. The study focused on CTNNB1, a gene that produces the protein β-catenin, which helps regulate tissue growth and repair. When β-catenin is disrupted, cells can begin uncontrolled growth – a hallmark of cancer. By systematically testing all possible mutations in a priority area of the gene in mouse cells, the map helps explain why certain mutations appear in specific cancers and could guide the development of new treatments, experts say. Many cancers carry mutations ...

A new study in Nature Geoscience reveals that changes in the West Antarctic Ice Sheet (WAIS) closely tracked marine algae growth in the Southern Ocean over previous glacial cycles, but not in the way scientists expected. The key factor is iron-rich sediments transported by icebergs from West Antarctica. Iron acts like fertilizer for algae. But when analyzing a sediment core taken from the Pacific sector of the Southern Ocean in 2001, more than three miles below the water’s surface, researchers were surprised to find that a high iron supply did not accelerate marine algae growth. “Normally, an increased supply of iron in the Southern Ocean would stimulate algae ...

People born more recently are being diagnosed with psychotic disorders (e.g., schizophrenia) more often and at younger ages than people born earlier, suggests a large study of more than 12 million people in Ontario, published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.250926. “Individuals with psychotic disorders face substantial morbidity and risk of premature death, and often require substantial health services and social support,” writes Dr. Daniel Myran, Gordon F. Cheesbrough ...

The fossils, representing at least five individuals, were first uncovered by Fidel Torcida Fernández-Baldor of the Dinosaur Museum of Salas de los Infantes. “From the beginning, we knew these bones were exceptional because of their minute size. It is equally impressive how the study of this animal overturns global ideas on ornithopod dinosaur evolution,” he notes. The genus name Foskeia is derived from the ancient Greek. The prefix fos means ‘light’, given the very lightweight and small body size of grown individuals (Dieudonné et al. 2023). The combination of letters ...

MADISON — The cells in our bodies move in groups during biological processes such as wound healing and tissue development — but because of resistance, or viscosity, those cells can't just neatly glide past each other.   Or can they? Using a pioneering method they developed to directly measure viscosity in a group of cells, University of Wisconsin–Madison engineers have made a surprising discovery that upends understanding of how cells move. It's called "negative viscosity," and it propels cells, rather than impedes ...

The paper, published in Nature Catalysis, demonstrates how the bacteria Escherichia coli can be engineered to produce these new molecules in ...

In 2023, more than half of all suicide deaths in the United States involved firearms. “Red flag” laws—also called Extreme Risk Protection Orders or ERPOs—are designed to reduce these deaths by authorizing temporary firearm removal from individuals deemed at high risk of harming themselves or others. ERPO laws had been implemented in 21 states and the District of Columbia as of February 2025.  But the laws’ effectiveness in preventing suicides was still unclear.   However, a new analysis ...

It’s common to wonder as tax season ramps up: Are taxes too high? According to a new study by University of Cincinnati economics professor David Brasington, the answer is no, at least when it comes to Ohio’s city service taxes. These taxes go toward local services such as funds for the fire department, road repair and park upkeep.  “It seems like public services are not over-provided at the local level in Ohio,” Brasington said. “Because good things seem to happen when people renew these taxes instead of cut them.” Brasington, PhD, published a new study in Regional Science and Urban Economics called “Effect ...

Hydrocephalus is a life-threatening condition that occurs in about 1 in 1,000 newborns and is often treated with invasive surgery. Now, a new study offers hope of preventing hydrocephalus before it even occurs. Also known as water on the brain, hydrocephalus is caused by a surplus of cerebral spinal fluid (CSF) that increases pressure inside the skull and can damage brain tissue. About 40 per cent of hydrocephalus cases are caused by single gene mutations which impact the brain’s ability to reabsorb CSF ...
