Generative artificial intelligence (AI) systems can be optimized using TextGrad, a framework that performs optimization by backpropagating large-language-model-generated feedback; TextGrad enables optimization across diverse tasks, including radiotherapy treatment plans and molecule generation.

Quantum technologies operate by leveraging various quantum mechanical effects, including entanglement. Entanglement occurs when two or more particles share correlated states even if they are distant.

When two particles are spin entangled, the intrinsic angular momentum (i.e., spin) of one particle can influence that of its entangled partner. This would suggest that the energy of the second particle can be altered via a nonlocal correlation, without enabling faster-than-light communication.

Researchers at Shanghai Jiao Tong University and Hefei National Laboratory recently carried out a study aimed at testing this theoretical prediction experimentally using two quantum memories.

In a groundbreaking study on the synthesis of cellulose—a major constituent of all plant cell walls—a team of Rutgers University-New Brunswick researchers have captured images of the microscopic process of cell-wall building continuously over 24 hours with living plant cells, providing critical insights that may lead to the development of more robust plants for increased food and lower-cost biofuels production.

The discovery, published in the journal Science Advances, reveals a dynamic process never seen before and may provide practical applications for everyday products derived from plants, including enhanced textiles, biofuels, biodegradable plastics, and new medical products.

The research is also expected to contribute to the fundamental knowledge while providing a new understanding of the formation of cell walls, the scientists said.

A process based on perovskite semiconductors is described to downscale micro-LEDs and nano-LEDs to below the conventional size limits, demonstrating average external quantum efficiencies maintained at around 20% across a wide range of pixel lengths.

Neura Robotics has built a diverse portfolio of robots, including MAiRA, the world’s first cognitive cobot. MAiRA uses artificial intelligence for autonomous operation and safe human interaction. The company also offers the MAV, a mobile robot for heavy load transport, and MiPA, a humanoid robot designed for tasks like serving trays in hospitals.

Through its cloud-based Neuraverse platform, Neura also creates cutting-edge software, in contrast to many robotics companies that only concentrate on hardware. Known as an “ecosystem for cognitive robotics,” the Neuraverse is a marketplace for robotic abilities and an operating system designed to spur innovation.

Many businesses displayed humanoid robots at CES 2025, demonstrating the momentum of the robotics sector. The humanoid robot “Melody,” created by Realbotix, is simple to assemble and disassemble. In the meantime, the full-size bipedal humanoid robot known as the “CASBOT 01” was introduced by China’s Lingbao CASBOT.

Quantum computers have the potential to solve complex problems that would be impossible for the most powerful classical supercomputer to crack.

Just like a classical computer has separate yet interconnected components that must work together, such as a memory chip and a CPU on a motherboard, a quantum computer will need to communicate quantum information between multiple processors.

Current architectures used to interconnect superconducting quantum processors are “point-to-point” in connectivity, meaning they require a series of transfers between network nodes, with compounding error rates.

The search giant should’ve been first to the chatbot revolution. It wasn’t. So it punched back with late nights, layoffs—and lowering some guardrails.
