Example of fluorine 18 fluorodeoxyglucose PET images from Alzheimer's Disease Neuroimaging Initiative set preprocessed with the grid method for patients with Alzheimer disease (AD). One representative zoomed-in section was provided for each of three example patients: A, 76-year-old man with AD, B, 83-year-old woman with mild cognitive impairment (MCI), and, C, 80-year-old man with non-AD/MCI. In this example, the patient with AD presented slightly less gray matter than did the patient with non-AD/MCI. The difference between the patient with MCI and the patient with non-AD/MCI appeared minimal to the naked eyes. Credit: Radiological Society of North America
Artificial intelligence (AI) technology improves the ability of brain imaging to predict Alzheimer's disease, according to a study published in the journal Radiology. Timely diagnosis of Alzheimer's disease is extremely important, as treatments and interventions are...
Aquatic animals that jump out of water inspire leaping robots
Ever watch aquatic animals jump out of the water and wonder how they manage to do it in such a streamlined and graceful way? A group of researchers who specialize in water entry and exit...

On one of the busiest traveling holidays of the year, drivers may be focusing on getting to grandma's house for Thanksgiving dinner, not on what smart car technologies are saving them in fuel costs. But...
Model of quantum artificial life on quantum computer
A scenario of artificial intelligence could see the emergence of circumstances in which models of simple organisms could be capable of experiencing the various phases of life in a controlled virtual environment. This is what...
Explaining the plummeting cost of solar power
The dramatic drop in the cost of solar photovoltaic (PV) modules, which has fallen by 99 percent over the last four decades, is often touted as a major success story for renewable energy technology. But...

Engineers at Duke University have demonstrated a device that can direct photons of light around sharp corners with virtually no losses due to backscattering, a key property that will be needed if electronics are ever...
Not all stars are like the sun, so not all planetary systems can be studied with the same expectations. New research from a University of Washington-led team of astronomers gives updated climate models for the...
