Researchers have developed a blueprint for weaving hopfions—complex, knot-like light structures—into repeating spacetime crystals. By exploiting two-color beams, they can generate ordered chains and lattices with tunable topology, potentially revolutionizing data storage, communications, and photonic processing. [...]

Researchers in Germany have unveiled the Metafiber, a breakthrough device that allows ultra-precise, rapid, and compact control of light focus directly within an optical fiber. Unlike traditional systems that rely on bulky moving parts, the Metafiber uses a tiny 3D nanoprinted hologram on a dual-core fiber to steer light by [...]

When I picked up my daughter from summer camp, we settled in for an eight-hour drive through the Appalachian mountains, heading from North Carolina to her grandparents’ home in Kentucky. With little to no cell service for much of the drive, we enjoyed the rare opportunity to have a long, [...]

Farmers Insurance is advising affected customers to "remain vigilant." [...]

Researchers have developed a new tool, bimodularity, that adds directionality to community detection in networks. Unlike traditional methods that only cluster nodes, this approach groups edges, making it possible to distinguish senders from receivers and uncover bicommunities. [...]

Researchers have created a new technology to maximize the effectiveness and reach of mRNA vaccines. [...]

On a mission to reduce the environmental impact of manufacturing components, Siemens turned its attention to the design of a robot gripper. Making up just 2% of the robot, the impact of this hand-like device may seem inconsequential. But, reducing its weight by 90% and the number of constituent parts by 84% [...]

A research team created a plant-inspired molecule that can store four charges using sunlight, a key step toward artificial photosynthesis. Unlike past attempts, it works with dimmer light, edging closer to real-world solar fuel production. [...]

Scientists have cracked one of chemistry’s toughest challenges with indoles, using copper to unlock a spot once thought too stubborn to change. The discovery could pave the way for easier, cheaper drug development. [...]

Environmental scientists are increasingly using enormous artificial intelligence models to make predictions about changes in weather and climate, but a new study by MIT researchers shows that bigger models are not always better.The team demonstrates that, in certain climate scenarios, much simpler, physics-based models can generate more accurate predictions than [...]

A hydrogen-based two-step annealing process improves SiC MOS device efficiency and reliability, expanding voltage range for electric vehicles and renewable energy systems. [...]

Stop me if you’ve heard this one before.  The AI learns it is about to be switched off and goes rogue, disobeying commands and threatening its human operators. It’s a well-worn trope in science fiction. We see it in Stanley Kubrick’s 1968 movie 2001: A Space Odyssey. It’s the premise of the [...]

Cognitive readiness denotes a person's ability to respond and adapt to the changes around them. This includes functions like keeping balance after tripping, or making the right decision in a challenging situation based on knowledge and past experiences. For military service members, cognitive readiness is crucial for their health and [...]

Back in the 17th century, German astronomer Johannes Kepler figured out the laws of motion that made it possible to accurately predict where our solar system’s planets would appear in the sky as they orbit the sun. But it wasn’t until decades later, when Isaac Newton formulated the universal laws [...]

Researchers discovered that bees use flight movements to sharpen brain signals, enabling them to recognize patterns with remarkable accuracy. A digital model of their brain shows that this movement-based perception could revolutionize AI and robotics by emphasizing efficiency over massive computing power. [...]

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they achieved a milestone that could transform how quantum computers scale. [...]

Researchers have developed an AI-powered tool called chronODE that models how genes turn on and off during brain development. By combining mathematics, machine learning, and genomic data, the method identifies exact “switching points” that determine when genes reach maximum activity. [...]

Using machine learning, MIT chemical engineers have created a computational model that can predict how well any given molecule will dissolve in an organic solvent — a key step in the synthesis of nearly any pharmaceutical. This type of prediction could make it much easier to develop new ways to [...]

Researchers have unveiled a new quantum material that could make quantum computers much more stable by using magnetism to protect delicate qubits from environmental disturbances. Unlike traditional approaches that rely on rare spin-orbit interactions, this method uses magnetic interactions—common in many materials—to create robust topological excitations. Combined with a new [...]

Researchers have built the first “microwave brain” chip capable of processing both ultrafast data and wireless communication signals at once.
