TL;DR: A genome-wide association meta-analysis of 20,183 individuals diagnosed with ADHD and 35,191 controls identifies variants surpassing genome- wide significance in 12 independent loci and implicates neurodevelopmental pathways and conserved regions of the genome as being involved in underlying ADHD biology.

TL;DR: Genetic influences on psychiatric disorders transcend diagnostic boundaries, suggesting substantial pleiotropy of contributing loci within genes that show heightened expression in the brain throughout the lifespan, beginning prenatally in the second trimester, and play prominent roles in neurodevelopmental processes.

TL;DR: Shade matching should not only be carried out in daylight conditions but under other light sources, as well as in the absence of sunshine.

Maximizing biomass productivity and cell density of Chlorella vulgaris by using light-emitting diode-based photobioreactor.
Weiqi Fu,Olafur O Gudmundsson,Adam M. Feist,Gisli Herjolfsson,Sigurdur Brynjolfsson,Bernhard O. Palsson,Bernhard O. Palsson +6 more
TL;DR: Growth results were improved under the less expensive light of 660 nm LEDs, and illumination was augmented by optimization at systematic level, providing for a biomass productivity of up to 2.11 gDCW/L/day, the best results ever reported.

Validity of Self-Report and Informant Rating Scales of Adult ADHD Symptoms in Comparison With a Semistructured Diagnostic Interview
Páll Magnússon,Jakob Smári,Dagbjörg Sigurdardóttir,Gisli Baldursson,Jón Sigmundsson,Kristleifur Kristjansson,Solveig Sigurdardóttir,Stefan Hreidarsson,Steingerdur Sigurbjörnsdóttir,Olafur O Gudmundsson +9 more
TL;DR: It was concluded that the rating scales have good psychometric properties, at least in at-risk populations, and predicted interview-based diagnoses in childhood and adulthood with adequate sensitivities and specificities.
