Abstract. Intelligence describes the general cognitive ability level of a person. It is one of the most fundamental concepts in psychological science and is crucial for the effective adaption of behavior to varying environmental demands. Changing external task demands have been shown to induce reconfiguration of functional brain networks. However, whether neural reconfiguration between different tasks is associated with intelligence has not yet been investigated. We used functional magnetic resonance imaging data from 812 subjects to show that higher scores of general intelligence are related to less brain network reconfiguration between resting state and seven different task states as well as to network reconfiguration between tasks. This association holds for all functional brain networks except the motor system and replicates in two independent samples (n = 138 and n = 184). Our findings suggest that the intrinsic network architecture of individuals with higher intelligence scores is closer to the network architecture as required by various cognitive demands. Multitask brain network reconfiguration may, therefore, represent a neural reflection of the behavioral positive manifold – the essence of the concept of general intelligence. Finally, our results support neural efficiency theories of cognitive ability and reveal insights into human intelligence as an emergent property from a distributed multitask brain network.

Higher levels of HDL-C—known as the “good cholesterol”—have been shown to correlate with heightened risk for Alzheimer’s disease.
A new study published in the Journal of Clinical Endocrinology & Metabolism might explain why.
BROWNSVILLE, Texas (ValleyCentral) — The Federal Aviation Administration approved the license on Saturday for the launch of Starship Flight 5.
The launch window begins at 7 a.m. on Sunday, Oct. 13th.
Oak Ridge National Laboratory’s new RODAS technology provides detailed insights into atomic changes in materials, critical for advancing quantum computing.
The method’s ability to analyze materials like molybdenum disulfide without damaging them marks a significant improvement over traditional techniques, offering potential breakthroughs in material science.
A team of researchers led by the Department of Energy’s Oak Ridge National Laboratory has developed a novel method for observing changes in materials at the atomic level. This technique opens new avenues for advancing our understanding and development of materials critical for quantum computing and electronics.
Researchers at the Department of Energy’s Oak Ridge National Laboratory, the University of Tennessee, and Texas A&M University demonstrated bio-inspired devices that accelerate routes to neuromorphic, or brain-like, computing.
Results published in Nature Communications report the first example of a lipid-based “memcapacitor,” a charge storage component with memory that processes information much like synapses do in the brain. Their discovery could support the emergence of computing networks modeled on biology for a sensory approach to machine learning.
“Our goal is to develop materials and computing elements that work like biological synapses and neurons—with vast interconnectivity and flexibility—to enable autonomous systems that operate differently than current computing devices and offer new functionality and learning capabilities,” said Joseph Najem, a recent postdoctoral researcher at ORNL’s Center for Nanophase Materials Sciences, a DOE Office of Science User Facility, and current assistant professor of mechanical engineering at Penn State.
Duke University engineers are layering atom-thick lattices of carbon with polymers to create unique materials with a broad range of applications, including artificial muscles.
The lattice, known as graphene, is made of pure carbon and appears under magnification like chicken wire. Because of its unique optical, electrical, and mechanical properties, graphene is used in electronics, energy storage, composite materials, and biomedicine.
Researchers have developed a novel graphene-germanium hot-emitter transistor using a new hot carrier generation mechanism, achieving unprecedented performance. This advancement opens new possibilities for low-power, high-performance multifunctional devices.
Transistors, the fundamental components of integrated circuits, encounter increasing difficulties as their size continues to shrink. To boost circuit performance, it has become essential to develop transistors that operate on innovative principles. Hot carrier transistors, which harness the extra kinetic energy of charge carriers, offer the potential to enhance transistor speed and functionality. However, their effectiveness has been constrained by conventional methods of generating hot carriers.
A team of researchers led by Prof. Chi Liu, Prof. Dongming Sun, and Prof. Huiming Cheng from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences has proposed a novel hot carrier generation mechanism called “stimulated emission of heated carriers (SEHC).” The team has also developed an innovative hot-emitter transistor (HOET), achieving an ultralow sub-threshold swing of less than 1 mV/dec and a peak-to-valley current ratio exceeding 100. The study provides a prototype of a low-power, multifunctional device for the post-Moore era.
