Of the 5,300 children enrolled in the Ohio Behavioral Health Juvenile Justice Initiative since 2006, 21% reported that someone close them had been murdered in the past year. Nearly half of the boys and more than a quarter of the girls in the program have both a substance abuse and mental health disorder.
But there's good news, too: From 2017 through 2019, 81% of the participants--aged 10 through 17--successfully completed the state's juvenile diversion program, and data indicated that 79% of youth reduced their contact with police while in treatment.

"Today's computer applications generate a large amount of data that needs to be processed by machine learning algorithms," says Yeseong Kim of Daegu Gyeongbuk Institute of Science and Technology (DGIST), who led the effort.
Arctic sea ice has been rapidly declining in recent decades, and changes in arctic sea ice can have a significant impact on global weather and climate through interactions with the atmosphere and oceans. In addition, the Arctic shipping routes are a shortcut to connect the major countries in the Northern Hemisphere. The Arctic region is also rich in natural resources and biological resources.
In an in-depth study of how COVID-19 affects a patient's brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease. In addition, they saw no signs of SARS-CoV-2 in the tissue samples, suggesting the damage was not caused by a direct viral attack on the brain. The results were published as a correspondence in the New England Journal of Medicine.
In a first-of-its-kind study within cycad horticulture literature, University of Guam researchers have found that the use of anti-transpirants neither help nor hinder successful propagation of cycad stem cuttings.
The Guam-based study, published Oct. 22 in the journal Tropical Conservation Science, investigated whether retaining leaves during the propagation of cycad stem cuttings conferred any benefit to propagation success. Additionally, two anti-transpirant products were utilized to investigate their efficacy during the propagation process.
The Grain Chain, a farm to fork coalition of stakeholders in the grain industry sector and chaired by the American Bakers Association (ABA), celebrates the recommendation published today in the 2020-2025 Dietary Guidelines for Americans (DGAs) to "consume half of your grains from whole grain sources" and the remainder from enriched grains. A foundational piece of the DGAs, the guidelines recognize whole grains are "one of the three food groups that are fundamental constituents of a healthy dietary pattern."
Researchers at the University of Turku have discovered what type of neural mechanisms are the basis for emotional responses to music. Altogether 102 research subjects listened to music that evokes emotions while their brain function was scanned with functional magnetic resonance imaging (fMRI). The study was carried out in the national PET Centre.
The researchers used a machine learning algorithm to map which brain regions are activated when the different music-induced emotions are separated from each other.
Cells, the basic unit of life, are surrounded by a limiting membrane called the plasma membrane. Inside cells, there are various membrane-bounded organelles, each of which has various and distinctive functions. How these organelles, which individually boast different functions, have been developed during evolution remains unknown. This phenomenon has fascinated many researchers.
New research produced jointly by The Swire Institute of Marine Science (SWIMS), Faculty of Science, The University of Hong Kong (HKU), and The Nature Conservancy (TNC), published recently in the scientific journal Restoration Ecology, shows the enormous potential of restoring lost oyster reefs, bringing significant environmental benefits.

Developing brains constantly sprout new neuronal connections called synapses as they learn and remember. Important connections -- the ones that are repeatedly introduced, such as how to avoid danger -- are nurtured and reinforced, while connections deemed unnecessary are pruned away. Adult brains undergo similar pruning, but it was unclear how or why synapses in the adult brain get eliminated.
Researchers at Tohoku University have developed the first all-in-one miniature pH probe for real-time investigations of intrinsic extracellular pH dynamics in the deep brain structures.
In our brain, over billions of dedicated workers --neurons and glial cells --form complex and efficient networks that constantly communicate with each other via subtle chemical signals to govern our behavioral output.
In the mountains across the world, different types of vegetation occur at different elevations creating distinct zones with well-defined borders between them. Each vegetation zone provides specific living conditions for animals. Therefore species that are adapted to habitats created in the specific zone occur only at the specific elevations and do not overlap with other species of similar ecology and behavior adapted to other vegetation zones at different elevations.
The gallium selenide monolayer has been recently discovered to have an alternative crystal structure and has diverse potential applications in electronics. Understanding its properties is crucial to understand its functions. Now, scientists from the Japan Advanced Institute of Science and Technology and the University of Tokyo have explored its structural stability, electronic states, and transformation of crystal phases.
Underwater excavation, borehole drilling, and modelling suggests a massive paleo-tsunami struck near the ancient settlement of Tel Dor between 9,910 to 9,290 years ago, according to a study published December 23, 2020 in the open-access journal PLOS ONE by Gilad Shtienberg, Richard Norris and Thomas Levy from the Scripps Center for Marine Archaeology, University of California, San Diego, USA, and colleagues from Utah State University and the University of Haifa.
