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 […]

Tiny Brain-Inspired Device Could Solve AI’s Biggest Energy Problem
Researchers have developed a brain-inspired nanoelectronic device that could significantly reduce the energy demands of artificial intelligence systems. Researchers have created a new type of nanoelectronic device that could significantly reduce the energy demands of artificial intelligence by taking inspiration from how the human brain works. A team led by the University of Cambridge developed […]
Honey Bees Dance Better When Someone Is Watching
Honey bees literally dance better when they have an audience. Honey bees don’t deliver perfect directions unless someone’s watching closely. When their audience shrinks, their famous waggle dance gets less accurate as they try to draw attention. “Dance like nobody’s watching” may be good advice for humans, but honey bees operate very differently. Over the […]
