Thin films of nickel and iron oxides yield efficient solar water-splitting catalyst

Researchers at the University of Oregon have developed ultra-thin films of nickel and iron oxides that demonstrate high catalytic activity for forming oxygen from water. The nickel-iron oxide catalyst was found to be most effective when just 0.4 nanometers thick, making it a promising material for solar-hydrogen production.

Natural climate swings contribute more to increased monsoon rainfall than global warming

The Northern Hemisphere monsoon has intensified, with a 9.5% increase in rainfall, due to natural climate swings rather than global warming alone. Natural long-term climate swings, such as the Interdecadal Pacific Oscillation and Atlantic Multidecadal Oscillation, contribute significantly more to this intensification.

Genomic data are growing, but what do we really know?

A large-scale evaluation of computational protein function prediction reveals that algorithms combining disparate prediction clues provide more accurate predictions, turning genomic data into useful information. The study provides a comprehensive picture of how well current methods perform, with potential improvements identified.

Atypical brain circuits may cause slower gaze shifting in infants who later develop autism

A new study found that 7-month-old infants who later develop autism show slower gaze shifting and attention reorientation compared to typically developing infants. The researchers suggest that atypical brain circuits, specifically the splenium of the corpus callosum, may contribute to this behavioral difference.

3-year olds know rules of sharing but don't follow them until older

A new study found that 3-year-olds endorse equal sharing norms, but fail to follow them until they reach 7-8 years old. Researchers gave stickers valued by children of all ages and asked about sharing, finding consistent endorsement across ages. However, actual behavior showed a gap between endorsed and followed norms.

Family dinners nourish good mental health in adolescents

A large community sample of adolescents found that regular family suppers were associated with fewer emotional and behavioral problems, greater emotional well-being, and higher life satisfaction. The study suggests that family mealtimes provide opportunities for open interactions and teaching positive health behaviors.

Clues point to cause of a rare fat-distribution disease

Researchers at Johns Hopkins Medicine have identified a novel modification of the lamin A protein that disrupts normal patterns of fat distribution in familial partial lipodystrophy (FPLD). The discovery provides new insights into the mechanisms underlying FPLD, a rare disease characterized by abnormal fat accumulation in certain areas...

Humanoid robot helps train children with autism

Researchers at Vanderbilt University developed a system to help children with autism learn joint attention, a basic social skill. The humanoid robot NAO was found to be effective in improving attention and following instructions, suggesting robots could play a crucial role in responding to the growing number of autism diagnoses.

Media coverage of mass shootings contributes to negative attitudes towards mental illness

A new study by Johns Hopkins Bloomberg School of Public Health confirms that news stories about mass shootings involving a shooter with mental illness contribute to negative perceptions of mental illness. Reading such articles raised readers' support for both gun restrictions for persons with serious mental illness and policies to ban ...

Restoration and recommendations for flood-damaged bottomlands

The US Army Corps of Engineers, USDA, and FEMA invested over $51 million in restoring the 2011 flood-damaged Birds Point-New Madrid floodway. Experts recommend revising the comprehensive plan to integrate levee engineering with ecological infrastructure to mitigate future flooding.
