Boron nitride is a crystalline material made of boron and nitrogen atoms arranged in a hexagonal lattice, giving it a two-dimensional structure that closely resembles graphene but with distinct electronic and optical properties. Credit: Shutterstock…
Researchers have created molecular devices that can change their electronic role on the fly, behaving like memory, logic, or even artificial synapses. By designing adaptable chemistry at the molecular level, they bring computing closer to…
Duke researchers have built an AI that uncovers simple laws behind complex, ever-changing systems by learning directly from data. The result is clear, compact models that help scientists understand, predict, and even spot instability in…
Researchers have made a key advance in thin-film solar cell technology by rethinking one of its most problematic regions: the interface between the light-absorbing material and the metal contact. Credit: Shutterstock The introduction of a…
A philosopher of consciousness argues that there may be no reliable way to determine whether artificial intelligence is truly conscious, making agnosticism the most defensible position. He warns that this deep uncertainty leaves room for…
A large study shows that AI can enhance creative thinking by encouraging exploration rather than efficiency alone. Credit: Shutterstock New research suggests that artificial intelligence may be most powerful not as a tool for automation,…
Researchers from several leading U.S. universities and industry have created a new kind of computer chip that stacks memory and computing vertically, dramatically improving how fast data can move inside the hardware. Credit: Shutterstock Stanford,…
A new 3D-printed aluminum alloy is stronger than traditional aluminum, due to a key recipe that, when printed, produces aluminum (illustrated in brown) with nanometer scale precipitates (in light blue). The precipitates are arranged in…
Global energy demand is rising rapidly, driven by data centers, advanced vehicles, and new manufacturing technologies. Researchers at NREL have developed an ultra-efficient, compact power module that can extract significantly more usable energy from existing…
