A study by University of Georgia doctoral student Matthew Harrison found that dark-skinned black applicants were less preferred than lighter-skinned counterparts with similar qualifications. This 'colorism' in hiring is rooted in societal perceptions associating light skin with attractiveness and intelligence.
A new study found that variations of the OLIG2 gene are strongly associated with schizophrenia. The gene plays a crucial role in myelin production and is coordinated with other genes involved in myelination and schizophrenia development. This causal link may help researchers develop new therapeutic targets for the debilitating illness.
Scientists found that massive erosion of the Alps was triggered by a sudden drop in Mediterranean Sea levels and prolonged warmer climate. The event, known as the Messinian salinity crisis, carved deep valleys and left behind lakes, reducing the mountain range's size over millions of years.
Researchers found that multi-sensory training programs significantly improve low-level perceptual tasks in adults. Engaging both vision and hearing can produce speedier learning and suggest modifications to adult perceptual systems.
A Stanford study found that boosting neuropeptide Y levels in the thalamus and hippocampus can reduce seizures. Researchers discovered that valproic acid increases neuropeptide Y production by 50% in these areas, offering a potential new approach to treating epilepsy with fewer side effects.
Researchers found that young women with asthma are twice as likely to experience symptoms of obstructive sleep apnea compared to those without asthma. Habitual snoring was reported by about 21% of these patients, highlighting the importance of identifying high-risk groups.
Researchers and clinicians discuss key issues in dementia diagnosis, including assessment tools and genetic research. The article highlights the importance of early and accurate diagnoses for treatment and progression, as new medications become available.

A large population-based study found that 2.4% of breast-cancer cases carried BRCA1 mutations and 2.3% carried BRCA2 mutations, with variations in mutation rates among different racial and ethnic groups. The study also identified predictors of carrying these mutations, including family history and age at diagnosis.
A new study found that over half of men with lower-risk prostate cancer received aggressive treatment, despite active surveillance being a viable option. Men under 55 were more likely to receive surgery, while those aged 70-74 were more likely to receive radiation.
Researchers found that infusing patients with low-dose ethanol, morphine or ketoconazole before and after surgery significantly reduced the incidence of pneumonia from 39% to 5.7%. The treatment also shortened ICU stay by 9 days in alcoholic patients undergoing aerodigestive tract surgery.
A study by Penn researchers found that truck drivers who get too little sleep or suffer from sleep apnea show signs of fatigue and impaired performance. The study examined 406 truck drivers and found that those with severe sleep apnea had performance impairment similar to that of drivers who are legally drunk.
