DALLAS - Feb. 10, 2020 - Artificial intelligence may soon play a critical role in choosing which depression therapy is best for patients.
A national trial initiated by UT Southwestern in 2011 to better understand mood disorders has produced what scientists are calling the project's flagship finding: a computer that can accurately predict whether an antidepressant will work based on a patient's brain activity.
As AI data sets get bigger and bigger, computers need more memory
New memory device uses pillar-shaped antiferromagnetic (AFM) materials
AFM materials are inherently fast, secure and require little power to read and write data
EVANSTON, Ill. -- Memory-hungry, power-sapping big data might finally have met its match.
Scientists at the University of Groningen turned a non-enzymatic protein into a new, artificial enzyme by adding two abiological catalytic components: an unnatural amino acid and a catalytic copper complex. This is the first time that an enzyme has been created using two non-biological components to create an active site. The study demonstrates that such a synergistic combination is a powerful approach to achieving catalysis that is normally outside the realm of artificial enzymes. The study was published in Nature Catalysis on 10 February.
Researchers at the Center for Nanoparticle Research, within the Institute for Basic Science (IBS, South Korea) in collaboration with collaborators at Zhejiang University, China, have reported a highly sensitive and specific nanosensor that can monitor dynamic changes of potassium ion in mice undergoing epileptic seizures, indicating their intensity and origin in the brain.
If we cross a road with our smartphone in view, a car horn or engine noise will startle us. In everyday life we can easily combine information from different senses and shift our attention from one sensory input to another - for example, from seeing to hearing. But how does the brain decide which of the two senses it will focus attention on when the two interact? And, are these mechanisms reflected in the structure of the brain?
Fuel cells turn chemicals into electricity. Now, a University of Toronto Engineering team has adapted technology from fuel cells to do the reverse: harness electricity to make valuable chemicals from waste carbon (CO2).
"For decades, talented researchers have been developing systems that convert electricity into hydrogen and back again," says Professor Ted Sargent, one of the senior authors of the paper published in Science. "Our innovation builds on that legacy, but by using carbon-based molecules, we can plug directly into existing hydrocarbon infrastructure."
The concept is based on the interaction of resonant semiconductor iron oxide Fe2O3 nanoparticles with light. Particles previously loaded with the antitumor drug are injected in vivo and further accumulate at the tumor areas. In order to release the drug non-invasively, the carrier particles have to be light-sensitive. For this purpose, the polymer containers (capsules) can be modified with iron oxide resonant semiconductor nanoparticles. When irradiated with light, they get heated and induce drug release. The research was published in Laser and Photonics Reviews.
Seurat Therapeutics, Inc. (Seurat) announced today the publication of preclinical studies of its lead product candidate, intranasal insulin-like growth factor-1 (IGF-1), in a rat model of migraine headaches, in the scientific journal Brain Research. The studies were conducted in Dr. Richard Kraig's laboratory at the University of Chicago. Seurat is the world-wide licensee of patents for nasal IGF-1 treatment of migraine headaches from the University of Chicago.
WEST LAFAYETTE, Ind. -- You don't have to be a drinker for your brain to be affected by alcoholism.
A new study shows that just having a parent with an alcohol use disorder affects how your brain transitions between active and resting states - regardless of your own drinking habits.
The study, performed by researchers at Purdue University and the Indiana University School of Medicine, discovered that the brain reconfigures itself between completing a mentally demanding task and resting.
LAWRENCE -- In the latest issue of The American Naturalist, University of Kansas investigator Jorge Sobero?n offers a new method for ecologists to calculate the correlation between geographic space and the number of species inhabiting that space.
