Roadsides may not look like wildlife habitat, but a few simple changes to how they are maintained could turn them into much better places for pollinators. A new uOttawa-led study found that reducing mowing and herbicide use along rural roadsides led to a 45% jump in pollinator numbers and a 23% increase in the number of species found there.

Scientists found a surprising driver of Alzheimer’s outside the brain
Scientists found that immune cells contributing to Alzheimer’s-related brain damage may be activated in lymph nodes outside the brain before traveling into the nervous system. Blocking this pathway in mice dramatically reduced neurodegeneration and preserved cognitive abilities,

“We found something never seen before” – A dead star is producing a shock wave that shouldn’t exist
A dead white dwarf with no detectable disk has somehow produced a powerful shock wave that appears to have persisted for at least 1,000 years. Its magnetic field may be partly responsible, but astronomers say an unexplained “mystery engine” may also be at work.

Marine biologists discover new plankton off Oregon coast
Nearly every morning when she was a doctoral student in the College of Arts and Sciences (CAS), Nicole Nakata, Ph.D. '23 (biology), would cross the street from the Oregon Institute of Marine Biology (OIMB) in Charleston, Ore., to the high-tide line of the Pacific Ocean. Her job w

Scientists discover first type I superconductor that breaks time-reversal symmetry
Superconductors are materials that conduct electricity with no resistance and expel magnetic fields when cooled to ultralow temperatures. And depending on their quantum structure, they can also showcase strange properties like magnetic levitation. But now things are getting a lit
