New research following US adolescents ages 11–12 shows that problematic use of mobile phones, social media, and video games was associated with higher risks of mental health problems, sleep disturbance, and suicidal behaviors one year later. The study in the American Journal of Preventive Medicine, published by Elsevier, reveals that the links between problematic screen use and mental health are stronger than those previously reported for overall screen time and highlights the risks of addictive use.

Cognitive impairment, including decreased attention and memory, remains one of the most disabling aspects of schizophrenia, affecting social life of patients. However, no effective treatment has yet been established for it. Now, researchers have investigated the effect of adding brexpiprazole on cognitive function in patients with schizophrenia. The findings revealed that patients with schizophrenia receiving adjunctive brexpiprazole showed a meaningful improvement in information processing speed, without worsening psychiatric symptoms.

The University of Tennessee and United Cleanup Oak Ridge (UCOR) have strengthened their 10-year formal partnership of developing highly skilled workers for nuclear and environmental cleanup work with an expanded Memorandum of Understanding focused on the increased importance of nuclear and criticality safety career opportunities at Department of Energy operations across the United States.

Seabird poop could have been used to fertilize Peru's Chincha Valley by at least 1250 CE, potentially facilitating the expansion of its pre-Inca society  

Higher self-reported levels of resilience were linked to lower anxiety and depression and better coping strategies during the COVID-19 pandemic, according to a study published February 11, 2026, in the open-access journal PLOS One by Joseph Anthony Pettit of Bangor University, U.K., and colleagues.

A male fruit fly in a laboratory chamber extends his wings and vibrates them to produce his species' version of a love song. A female fly stays nearby listening. Suddenly, a green light flashes across the chamber for a fraction of a second. The male's song cuts off mid-note and his wings fold. The female, not impressed by the interrupted serenade, walks away. The culprit? An AI system that watched the male begin his courtship dance and shut down his song-producing brain cells. Developed by scientists at Nagoya University and their collaborators from Osaka University and Tohoku University, the AI can watch and recognize animal behaviors and control the specific brain circuits that drive them. Published in Science Advances, the study presents an advanced AI system that can identify which animal performs a behavior in a group and selectively target only that animal’s brain cells during social interactions.
