Neuromorphic Computing from the Computer Science Perspective: Algorithms and Applications

Posted by in categories: information science, robotics/AI, science, transportation

Speaker’s Bio: Catherine (Katie) Schuman is a research scientist at Oak Ridge National Laboratory (ORNL). She received her Ph.D. in Computer Science from the University of Tennessee (UT) in 2015, where she completed her dissertation on the use of evolutionary algorithms to train spiking neural networks for neuromorphic systems. She is continuing her study of algorithms for neuromorphic computing at ORNL. Katie has an adjunct faculty appointment with the Department of Electrical Engineering and Computer Science at UT, where she co-leads the TENNLab neuromorphic computing research group. Katie received the U.S. Department of Energy Early Career Award in 2019.

Talk Abstract: Neuromorphic computing is a popular technology for the future of computing. Much of the focus in neuromorphic computing research and development has focused on new architectures, devices, and materials, rather than in the software, algorithms, and applications of these systems. In this talk, I will overview the field of neuromorphic from the computer science perspective. I will give an introduction to spiking neural networks, as well as some of the most common algorithms used in the field. Finally, I will discuss the potential for using neuromorphic systems in real-world applications from scientific data analysis to autonomous vehicles.

New nuclei can help shape our understanding of fundamental science on Earth and in the cosmos

Posted by in categories: physics, science, space

In creating five new isotopes, an international research team working at the Facility for Rare Isotope Beams (FRIB) at Michigan State University has brought the stars closer to Earth.

The —known as thulium-182, thulium-183, ytterbium-186, ytterbium-187 and lutetium-190—are reported in the journal Physical Review Letters.

These represent the first batch of new isotopes made at FRIB, a user facility for the U.S. Department of Energy Office of Science, or DOE-SC, supporting the mission of the DOE-SC Office of Nuclear Physics. The new isotopes show that FRIB is nearing the creation of nuclear specimens that currently only exist when ultradense celestial bodies known as crash into each other.

Altermagnets: A new chapter in magnetism and thermal science

Posted by in categories: materials, science

In a new study, scientists have investigated the newly discovered class of altermagnetic materials for their thermal properties, offering insights into the distinctive nature of altermagnets for spin-caloritronic applications.

Magnetism is an old and well-researched topic, lending itself to many applications, like motors and transformers. However, new magnetic materials and phenomena are being studied and discovered, one of which is altermagnets.

Altermagnets exhibit a unique blend of magnetic characteristics, setting them apart from conventional magnetic materials like ferromagnets and antiferromagnets. These materials exhibit properties observed in both ferromagnets and antiferromagnets, making their study enticing.

Heart-to-heart connection: Collaboration brings a breakthrough science exhibit to life

Posted by in categories: biotech/medical, science

One of the country’s best-known science museums, San Francisco’s Exploratorium, is located less than three miles north of Gladstone Institutes—proximity that has resulted in creative, high-science collaborations like the permanent exhibit featured in the latest issue of Stem Cell Reports.

Among the museum’s most popular exhibits, “Give Heart Cells A Beat” opens a rare window into the microscopic world of the beating human heart, using technology and materials made possible through Gladstone’s science and expertise. With the exhibit, the team created the first interactive museum experience that allows the public to interact directly with living cardiomyocytes.

In the AI science boom, beware: your results are only as good as your data

Posted by in categories: biotech/medical, chemistry, robotics/AI, science

We are in the middle of a data-driven science boom. Huge, complex data sets, often with large numbers of individually measured and annotated ‘features’, are fodder for voracious artificial intelligence (AI) and machine-learning systems, with details of new applications being published almost daily.

But publication in itself is not synonymous with factuality. Just because a paper, method or data set is published does not mean that it is correct and free from mistakes. Without checking for accuracy and validity before using these resources, scientists will surely encounter errors. In fact, they already have.

In the past few months, members of our bioinformatics and systems-biology laboratory have reviewed state-of-the-art machine-learning methods for predicting the metabolic pathways that metabolites belong to, on the basis of the molecules’ chemical structures1. We wanted to find, implement and potentially improve the best methods for identifying how metabolic pathways are perturbed under different conditions: for instance, in diseased versus normal tissues.

As Artificial Intelligence (AI) continues to advance by leaps and bounds, it’s impossible to overlook the profound transformations that this technological revolution is imprinting on the professions of the future. A paradigm shift is underway, redefining not only the nature of work but also how we conceptualize collaboration between humans and machines.

As creator of the ETER9 Project (2), I perceive AI not only as a disruptive force but also as a powerful tool to shape a more efficient, innovative, and inclusive future. As we move forward in this new world, it’s crucial for each of us to contribute to building a professional environment that celebrates the interplay between humanity and technology, where the potential of AI is realized for the benefit of all.

In the ETER9 Project, dedicated to exploring the interaction between artificial intelligences and humans, I have gained unique insights into the transformative potential of AI. Reflecting on the future of professions, it’s evident that adaptability and a profound understanding of technological dynamics will be crucial to navigate this new landscape.

Cincinnati Museum Center’s partnership with Elevation Science will expand dinosaur fossil collection

Posted by in categories: biotech/medical, evolution, science

“You need to go back hundreds of million years to understand the full picture of life,” he said. “Fossils are the database for deep-time studies.”

Paleontology may be a look back into the deep past, but it also plays a role in our future.

“Paleontology, and dinosaurs in particular, is a fantastic gateway into science, because all kids are interested in dinosaurs,” Storrs said. “It’s great if they go on to become scientists, but at the very least, they can be part of an informed citizenry that has a basic knowledge of the world and how science operates, because there’s always going to be questions about vaccines for example, or evolution, or climate change. Science plays a huge role in our world today.”
