Researchers from the University of Copenhagen have become the first in the world to mathematically prove that, beyond simple problems, it is impossible to develop algorithms for AI that will always be stable. ChatGPT and similar machine learning-based technologies are on the rise. However, even the most advanced algorithms face limitations. Researchers from the University of [...]
Researchers at City of Hope and Translational Genomics Research Institute (TGen) have developed and tested an innovative machine-learning approach that could one day enable the earlier detection of cancer in patients by using smaller blood draws. The study is published in the journal Science Translational Medicine. "A huge body of evidence shows that cancer caught at later stages [...]
Cryptocurrency is usually "mined" through the blockchain by asking a computer to perform a complicated mathematical problem in exchange for tokens of cryptocurrency. But in research appearing in the journal Chem a team of chemists has repurposed this process, asking computers to instead generate the largest network ever created of chemical reactions which may have given rise to [...]
A team of researchers from the Institute for Optoelectronic Systems and Microtechnology at Universidad Politécnica de Madrid (UPM) has designed a biosensor capable of identifying proteins and peptides in quantities as low as a single monolayer. For that, a surface acoustic wave (SAW), a kind of electrically controlled nano earthquake on a chip, is [...]
Cynthia Horton’s earaches are the stuff of nightmares. “I can wake up from my sleep in horrible pain, like I’m having a root canal with no anesthesia,” she said. “When I sit up, my ear is often weeping with infection, even oozing blood.” Already weakened by a lifelong battle with lupus, Horton’s immune system was [...]
The study hypothesizes that ‘pre-digested’ foods contributed to the development of larger brains. The large, capable human brain is a marvel of evolution, but how it evolved from a smaller primate brain into the creative, complex organ of today is a mystery. Scientists can pinpoint when our evolutionary ancestors evolved larger brains, which roughly tripled in [...]
Neuroscientists demonstrate how the brain improves its ability to distinguish between similar experiences, findings that could lead to treatments for Alzheimer’s disease and other memory disorders. Think of a time when you had two different but similar experiences in a short period. Maybe you attended two holiday parties in the same week or gave two presentations [...]
Sensors built with a new manufacturing approach are capable of recording activity deep within the brain from large populations of individual neurons—with a resolution of as few as one or two neurons—in humans as well as a range of animal models, according to a study published in the Jan. 17, 2024 issue of the [...]
A team of international researchers, led by Francesca Santoro from Jülich, has developed a biochip that imitates the human retina. This innovation is part of a broader effort in bioelectronics aimed at repairing bodily and brain dysfunctions. The creation of this chip is a collaborative achievement involving experts from Forschungszentrum Jülich, RWTH Aachen University, Istituto [...]
The brain, despite its comparatively shallow structure with limited layers, operates efficiently, whereas modern AI systems are characterized by deep architectures with numerous layers. This raises the question: Can brain-inspired shallow architectures rival the performance of deep architectures, and if so, what are the fundamental mechanisms that enable this? Neural network learning methods are [...]
