Everyday discrimination impacts mental health

Researchers found that African Americans and Caribbean blacks who experience discrimination are at higher risk for anxiety, depression, and substance abuse. The type and frequency of discrimination matter, with hostile and character-based discrimination placing adults at considerable risk for mental health problems.

International study identifies new genetic variants indicating risk for prostate cancer

A global study of over 87,000 individuals from diverse ethnic backgrounds has discovered 23 new genetic factors that contribute to the development of prostate cancer. The research, led by Keck School of Medicine at USC, provides valuable insights into the causes of this disease and may lead to better prevention strategies.

You don't walk alone

A new electroencephalography (EEG) tool has been developed to detect refractory idiopathic epilepsy in children, a condition that cannot be managed by antiepileptic drugs. The tool uses EEG classification analysis and identifies significant EEG features that distinguish refractory epilepsy from well-controlled forms.

Getting hot and wet in Vermont

A new study by University of Vermont scientists predicts increased precipitation and temperature in the Lake Champlain region, leading to more extreme weather events and potential flooding. The forecast suggests a rise in average temperatures by mid-century, with some ski resorts experiencing a 50% decline in annual snowfall.

Sleep disorders widely undiagnosed in individuals with multiple sclerosis

A large-scale study found that more than 70% of individuals with multiple sclerosis screened positive for one or more sleep disorders, highlighting the importance of diagnosing and managing these conditions. The study's findings suggest that sleep problems may be a hidden epidemic in the MS population, separate from MS fatigue.

Extension of standard model by knot algebra

The article proposes a connection between SLq(2) and the standard model, where preons are creation operators for fundamental particles. This extension describes a finer level of structure than the standard model, with open problems including gravitational binding and renormalization.

Moving silicon atoms in graphene with atomic precision

Researchers at the University of Vienna successfully manipulated individual silicon atoms in graphene, revealing a previously unknown phenomenon where the silicon-carbon bond is inverted. This discovery opens promising possibilities for atomic-scale engineering and could lead to the creation of unique quantum structures.
