Scientists have built a 98-qubit machine that they say performs better than any other quantum computer in the world. They’ve used it to gain new insights into superconducting physics.

A genetic switch lets plants accept nitrogen-fixing bacteria
Researchers are one step closer to understanding how some plants survive without nitrogen. Their work could eventually reduce the need for artificial fertilizer in crops such as wheat, maize, or rice.
“We are one step closer to greener and climate-friendlier food production,” say Kasper Røjkjær Andersen and Simona Radutoiu, both professors of molecular biology at Aarhus University. The findings are published in the journal Nature.
The two researchers led a new study where they discovered an important key to understanding how we can reduce agriculture’s need for artificial fertilizer.
3D-object-making machine forgoes printing for knitting
If you find 3D printers to be just a little too coldly futuristic, this contraption might be more to your liking. Scientists from Cornell University have created a machine that knits solid 3D objects out of nice old-timey conventional yarn.
The prototype device is made mainly of 3D-printed components, and incorporates a bed of knitting needles arranged in a 6 × 6 block. A motorized knitting head dispenses yarn to any of those needles in sequence, as determined by a program on a computer that’s controlling it.
Each of the needles in turn consists of a 3D-printed symmetrical double hook connected to a brass support tube. Because the front and rear sections of the hook move independently, it’s possible for the device to either knit or purl, depending on which section of the hook picks up the first loop of yarn.
Scientists Crack the Code Behind a Rare Cancer-Fighting Compound
Scientists at UBC Okanagan have revealed how plants create mitraphylline, a rare natural substance that shows potential for fighting cancer.
Mitraphylline is part of a small family of plant molecules known as spirooxindole alkaloids. These compounds are distinguished by their complex “twisted” ring structures and are recognized for powerful biological effects, including anti-tumor and anti-inflammatory activity.
Until recently, researchers did not know the precise molecular process plants use to form spirooxindoles. That mystery began to unravel in 2023 when Dr. Thu-Thuy Dang’s team in the Irving K. Barber Faculty of Science identified the first plant enzyme capable of twisting a molecule into the distinctive spiro shape.
A breakthrough map reveals how the brain really works
Scientists have shown that brain connectivity patterns can predict mental functions across the entire brain. Each region has a unique “connectivity fingerprint” tied to its role in cognition, from language to memory. The strongest links were found in higher-level thinking skills that take years to develop. This work lays the groundwork for comparing healthy and disordered brains.
