White, pink noise improve focus for children with ADHD

A systematic review of 13 studies found that white and pink noise improved cognitive performance in children and young adults with ADHD, but had no effect on those without the condition. Researchers believe this could be a promising new tool to empower individuals with ADHD to live healthier and more productive lives.

How scientists designed centered error entropy-based sigma-point Kalman Filter

Researchers designed a centered error entropy-based sigma-point Kalman Filter to enhance the filtering algorithm's robustness in spacecraft attitude determination. The proposed CEEUKF outperformed classical methods and other robust algorithms in simulating non-Gaussian noise, achieving higher accuracy and faster convergence rates.

Good noise, bad noise: White noise improves hearing

Researchers from the University of Basel found that adding white noise to a quiet environment improves the brain's ability to distinguish subtle tone differences. This is achieved through reduced neuronal activity in the auditory cortex, allowing for more precise sound perception and potentially improving cochlear implant results.

The smell of white

Scientists have created a blended scent, known as 'Laurax,' which spans the entire range of human olfaction and is perceived as neutral. This breakthrough challenges conventional wisdom on how our sense of smell works.

Pulling a fast one

Research by Northwestern University and Wake Forest University found that fast disclaimers undermine consumers' trust in unfamiliar brands, while trusted brands remain unaffected. Trusted brands can use fast disclaimers without impact on purchase intention.

'Louder at the back, please'

A new study found that playing white noise in class can improve the memory of schoolchildren with difficulties in paying attention. The researchers discovered a significant improvement in performance for inattentive children and a decline in performance for attentive ones as noise levels increased.

Patients' favorite music during surgery lessens need for sedative

Researchers at Yale University found that playing a patient's favorite music during surgery reduces the need for sedatives. In contrast, using white noise or no headphones did not decrease sedative requirements. The study involved 36 patients at Yale-New Haven Hospital and 54 patients at the American University of Beirut Medical Center.

Blacks' Environmental Concerns Equal/Exceed Whites'

A recent study by the University of Michigan found that Blacks' environmental concerns equal or exceed those of whites, with greater concern about local pollution and poorer environmental quality. The survey of 793 people identified significant differences in environmental attitudes between Black and white neighborhoods.
