New Haven, Conn. — Parents are much less likely to intervene when their young children are getting dressed or performing other simple chores if those tasks are framed as learning opportunities, according to a new study by Yale researchers.   Media reports and academic literature suggest that overparenting — a style of parenting in which adults persistently take over tasks or solve problems that would be developmentally appropriate for children to resolve on their own — is becoming ...

The Golgi apparatus modifies, sorts and packages proteins to be sent to their final destinations, whether that’s within or outside of the cell.   It’s a core function, but little studied in the setting of cancer immunology, especially when compared to other organelles like the mitochondria or endoplasmic reticulum.   “So we were interested in looking a little bit more at the Golgi apparatus. It's obviously an important organelle. How is it being changed or what is its role in T-cells in terms of fighting cancer?” said Nathaniel Oberholtzer, an M.D./Ph.D. student who worked in the lab of ...

The researchers detailed their findings in a paper published on November 16, 2024, in the International Journal of Machine Tools and Manufacture.   “Previous research has normally focused on reducing one type of defect, but that would ...

New Curtin University-led research has uncovered what may be the oldest direct evidence of ancient hot water activity on Mars, revealing the planet may have been habitable at some point in its past.   The study analysed a 4.45 billion-year-old zircon grain from the famous Martian meteorite NWA7034, also known as Black Beauty, and found geochemical ‘fingerprints’ of water-rich fluids.   Study co-author Dr Aaron Cavosie from Curtin’s School of Earth and Planetary Sciences said the discovery opened up new avenues for understanding ancient Martian hydrothermal systems associated ...

In an era of dwindling glaciers, Southern Patagonia has managed to hold on to a surprising amount of its ice. But, A new study in Scientific Reports from INSTAAR postdoc Matthias Troch suggests that this protective effect might be pushed up against its limits soon. Before making predictions, Troch and his collaborators looked back in time. They used an equation that, when plugged into NASA’s ice-sheet and sea-level system model, simulated glacial dynamics for the past six millenia. The results showed that precipitation, not temperature, was the main culprit of glacier fluctuation during around 4,500, of the past 6,000 years, or 76 percent of the time. In ...

People’s preference for simple explanations of any situation is connected to their desire to execute tasks efficiently, finds a new study from the University of Waterloo. "These findings show that our preference for simpler explanations mirrors how we evaluate actions. Simplicity isn't just valued in explanations—it's part of how we think about achieving results efficiently," said Claudia Sehl, lead author and a PhD candidate in developmental psychology at Waterloo. Sehl collaborated with Waterloo developmental psychology professors Ori Friedman and Stephanie Denison on this study. They conducted seven experiments involving 2,820 ...

Most ants have two morphologically differentiated adult castes - queens and workers - each irreversibly specialized for either reproduction or nonreproductive altruism such as foraging, defense and care of maternal brood. Adult gynes (virgin queens) normally have higher body mass, wings and frontal eyes, as well as enlarged ovaries and a sperm storage organ. In contrast, workers are wingless females with smaller body size and degenerated reproductive tracts, usually without a sperm storage organ. In 1910, the American entomologist ...

Expectant mothers who maintain a diet that meets USDA dietary guidelines during pregnancy may be more likely to have infants with healthy birthweights, steadier growth patterns, and potentially a reduced risk of obesity later in childhood, according to a new study funded by the Environmental influences on Child Health Outcomes (ECHO) Program at the National Institutes of Health. The research, involving more than 2,800 mother-child pairs across eight ECHO Cohort Study Sites, suggests that following a healthy ...

Dynamic, reversible modifications of DNA and RNA regulate how genes are expressed and transcribed, which can influence cellular processes, disease development, and overall organismal health. Small nucleolar RNAs (snoRNAs) are a common but overlooked group of guide RNA molecules that steer chemical modifications to cellular ribosomal RNA (rRNA) targets, like an usher showing someone to their seat in a theater. Researchers from the University of Chicago recently developed a new approach for identifying new cellular RNA targets of snoRNAs. ...

Hydrogen is becoming an increasingly popular choice as we shift towards cleaner energy. It can be burned like traditional fuels, producing only water as a byproduct, and can generate electricity when used in fuel cells. However, as hydrogen production, use, and transportation increase, so do safety concerns. Hydrogen is highly flammable at concentrations as low as 4% and is odorless and colorless, making leaks challenging to detect. To address these concerns, researchers led by Professor Yutaka Majima from Institute of Science Tokyo (Science Tokyo) have developed a sensor that detects hydrogen at ultra-low concentrations ...
