Immigrant, refugee youth most likely to visit the ED with a new mental health problem

A study published in CMAJ found that immigrant and refugee youth are more likely to visit emergency departments for new mental health issues, highlighting gaps in access to outpatient mental health care. The study suggests that barriers to primary care services, including language and cultural differences, contribute to this issue.

Lehigh professor Panos Diplas elected ASCE fellow

Dr. Panos Diplas, a Lehigh University professor, has been elected as an ASCE Fellow for his distinguished work in civil engineering and research on river phenomena such as scour and meandering. His team's studies aim to improve bridge stability and mitigate the effects of river movement on ecosystems.

Metal leads to the desired configuration

Researchers found a way to change the spatial arrangement of bipyridine molecules on surfaces using metals, which can improve dye-sensitized solar cells. The cis configuration is formed through the addition of iron atoms and increased temperature, altering the chemical conformation.

HKBU scholar discovers strong evidence for links between drying climate and human evolution

African lake sedimentary cores revealed a continuous record of climate change extending back one million years, linking aridification to technological and evolutionary changes in early humans. The research suggests that climate variability drove human migration and the development of new tools, providing a selective pressure for survival.

Researchers discover new type of stellar collision

An international team of astrophysicists has identified the first-ever merger of white and brown dwarf stars, with the debris left behind exhibiting unusual chemical compositions and organic molecules. The discovery sheds new light on the origin of a mysterious star observed by French monk Père Dom Anthelme in 1670.

Quantum momentum

The University of Delaware is leading the charge in quantum technology research with a $1 million NSF grant. The team aims to develop quantum electronics that can process information faster and with greater accuracy, enabling next-generation technologies for communication, computing, and sensing.

'Sentinels of the sea' at risk from changing climate

A new study finds that oyster mortality in the French Atlantic coast is linked to warm and wet winters, and the positive phase of the North Atlantic Oscillation. Oysters are sensitive to climate change and water quality, making them sentinels of coastal ecosystem health.

Neuron death in ALS more complex than previously thought

Researchers have discovered that two types of motor neurons die in ALS patients through distinct mechanisms, potentially leading to the development of more targeted treatments. The study used worm models to investigate the degeneration of spinal and brain neurons in ALS, revealing new insights into the complex nature of the disease.

Abrikosov vortices help scientists explain inconsistencies in 'dirty' superconductors theory

Researchers found that 'very dirty' superconductors exhibit abnormal behavior, violating the conventional theory of superconductivity. They discovered a power-law dependence between critical current density and magnetic field strength, allowing for a new understanding of Abrikosov vortices thermal fluctuations.

Downward mobility link to violent crime and self-harm

A major new study finds that children from families who fall on hard times are more likely to be involved in violent crime and harm themselves as young adults. Children from the poorest fifth of society were 7-13 times more likely to commit violent crime or self-harm compared to those from wealthier backgrounds.
