Medical Xpress / Parkinson's-linked α-synuclein blocks protein transport in neurons, disrupting cells' waste recycling
Parkinson's disease affects more than 10 million people worldwide. The disease is characterized by the buildup of abnormal clumps of the protein alpha-synuclein inside brain cells, but scientists have long struggled to understand ...
Medical Xpress / Radiopharmaceutical may benefit patients with metastatic prostate cancer sooner
Earlier use of a targeted radionuclide therapy delays metastatic prostate cancer progression when administered as part of a trio of drugs, according to a Phase III clinical trial led by Weill Cornell Medicine, NewYork-Presbyterian, ...
Phys.org / Songbirds may have developed sharper senses to de-husk seeds
Songbirds, birds belonging to the Passeriformes order, are best known for their ability to produce complex musical sounds. Yet some songbird species also have another remarkable skill: They can easily remove the tough layer ...
Phys.org / First measurement of antineutrinos from spent nuclear fuel confirms emissions persist after reactor shutdown
Even when the lights go out and nuclear reactors are turned off, the story inside the reactor core still has a great deal to tell. Radioactive, long-lived fission products continue to decay for months or even years, producing ...
Medical Xpress / Barbie and Ken get a reality check after 30 years
She's the blonde bombshell and he's her square-jawed sidekick. But nearly 70 years after the impossibly perfect Barbie and Ken made their debut, a new study from Adelaide University and UNSW Sydney shows the iconic pair are ...

Phys.org / Birdsong and whale song show patterns similar to human language
An international team of researchers has uncovered a previously undetected structure in the birdsong of Bengalese finches that has the same statistical patterns found in human languages.
Medical Xpress / Everyday packaging plastic may compound fatty liver risk from burgers and sodas
Microplastics have become nearly impossible to avoid. They have been detected in oceans, drinking water and even the human body, but scientists are still uncovering how they affect human health. Now, researchers at the Texas ...
Medical Xpress / Brain activity reveals two stages of visual processing before conscious perception
Seeing feels immediate; we open our eyes and the world seems to appear as a continuous stream. But some visual illusions show that events occurring later can change how we perceive what happened earlier, suggesting that the ...
