A naked-eye star’s 50-year mystery is solved—its bizarre X-rays come from a hidden, feeding white dwarf. Easily visible in the night sky within the constellation Cassiopeia, the star γ Cas has puzzled astronomers for more than 50 years. It produces X-rays with energies and temperatures far beyond what is expected from a typical massive star. […]
Study Challenges Long-Held Belief About Parkinson’s Tremors
New imaging research challenges a long-standing assumption about Parkinson’s disease. A clinical imaging study from Finland suggests that rest tremor in Parkinson’s disease is not caused by greater dopamine loss. Instead, tremor appears to be linked to relatively preserved dopamine function. Researchers at the University of Turku and Turku University Hospital analyzed clinical records along […]

Scientists Say One Gene Could Be Behind up to 93% of Alzheimer’s Cases
A growing body of evidence suggests that a single gene, APOE, may play a far more dominant role in Alzheimer’s disease than previously recognized. A single gene may play a much larger role in Alzheimer’s disease than scientists once thought. In a new analysis led by researchers at UCL, the APOE gene was linked to […]
Scientists Break Light’s Limits With “Narwhal” Wavefunctions
A long-standing limitation in photonics may be giving way to a new regime of light control. Photonic technologies have struggled to shrink at the same pace as electronics. The limitation comes from basic physics. The uncertainty principle links how tightly light can be confined to its wavelength, which in the visible and near-infrared range can […]
