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.

But a team including Zhang has a suggestion for what might have caused it: the merger of a neutron star not with another neutron star, as is common for short gamma ray bursts, but with a white dwarf. White dwarfs are larger than neutron stars, but not nearly as big as the massive stars that cause supernovae, which would account for the length and intensity of the unusual burst.

Since there are lots of white dwarf-neutron star binaries and events like this are rare enough that it’s the first to be observed in half a century of looking, he suggests it needs some qualifications: first, the white dwarf needs to be “close to the upper mass limit,” and afterwards the two need to merge into a rapidly-spinning magnetar, which would “inject additional energy into the kilonova.”

Government support is needed, however, to help consumers overcome heat pumps’ higher upfront costs relative to alternatives. The costs of purchasing and installing a heat pump can be up to four times as much as those for a gas boiler. Financial incentives for heat pumps are now available in 30 countries.

In the IEA’s most optimistic scenario – in which all governments achieve their energy and climate pledges in full – heat pumps become the main way of decarbonising space and water heating worldwide. The agency estimates that heat pumps have the potential to reduce global carbon dioxide (CO₂) emissions by at least 500 million tonnes in 2030 – equal to the annual CO₂ emissions of all cars in Europe today. Leading manufacturers report promising signs of momentum and policy support and have announced plans to invest more than US$4 billion in expanding heat pump production and related efforts, mostly in Europe.

Opportunities also exist for heat pumps to provide low-temperature heat in industrial sectors, especially in the paper, food, and chemicals industries. In Europe alone, 15 gigawatts of heat pumps could be installed across 3,000 facilities in these three sectors, which have been hit hard by recent rises in natural gas prices.

While studying how bio-inspired materials might inform the design of next-generation computers, scientists at the Department of Energy’s Oak Ridge National Laboratory achieved a first-of-its-kind result that could have big implications for both edge computing and human health.

Results published in Proceedings of the National Academy of Sciences show that an artificial cell membrane is capable of long-term potentiation, or LTP, a hallmark of biological learning and memory. This is the first evidence that a cell membrane alone—without proteins or other biomolecules embedded within it—is capable of LTP that persists for many hours. It is also the first identified nanoscale structure in which memory can be encoded.

“When facilities were shut down as a result of COVID, this led us to pivot away from our usual membrane research,” said John Katsaras, a biophysicist in ORNL’s Neutron Sciences Directorate specializing in neutron scattering and the study of biological membranes at ORNL.

Many philosophers endorse physicalism, the view that everything is physical. But what is a physical property?
