In a new study published in Nature, physicists at Brown University have now observed a novel class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists’ understanding of the quantum realm.

New points-to-consider

—

The transition from adolescence to adulthood is a critical period for young people, and perhaps even more for those having juvenile-onset rheumatic and musculoskeletal diseases (jRMDs). EULAR – The European Alliance of Associations for Rheumatology convened a task force of 26 experts from 10 European countries which established new points-to-consider for transitional care in rheumatology. These guidelines focus on patient education, aiming to empower young patients to manage their physical activity and pain.

Texas A&M University researchers asked 2,904 adults in the United States about their support for programs that required two administrative burdens: in-person interviews and submitting government-issued documents for verification purposes. They also asked for opinions about reducing these burdens by using presumptive eligibility—allowing access to services before a full application is processed—and “express lane” eligibility—verifying eligibility using information available from other government programs—for Social Security, Medicare, Medicaid, and Temporary Assistance for Needy Families (TANF) in the United States.
