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.

On-chip quantum interference of indistinguishable single photons from integrated independent molecules

Hong–Ou–Mandel experiments on a quantum photonic chip demonstrate on-chip quantum interference of indistinguishable single photons with visibilities exceeding 0.97 for two molecules separately coupled to two waveguides.

Super recognizers’ unique eye patterns give AI an edge in face matching tasks

What is it that makes a super recognizer —someone with extraordinary face recognition abilities—better at remembering faces than the rest of us?

According to new research carried out by cognitive scientists at UNSW Sydney, it’s not how much of a face they can take in—it comes down to the quality of the information their eyes focus on.

“Super-recognizers don’t just look harder, they look smarter. They choose the most useful parts of a face to take in,” says Dr. James Dunn, lead author on the research that was published in the journal Proceedings of the Royal Society B: Biological Sciences.

Landscape clues suggest Indigenous Peoples have thrived in southwestern Amazon for more than 1,000 years

In September 2021, a multidisciplinary expedition explored one of the least-known regions of the Bolivian Amazon: the Great Tectonic Lakes of Exaltación in the department of Beni.

Organized by the Grupo de Trabajo para los Llanos de Moxos (GTLM), the mission brought together researchers from the Wildlife Conservation Society, the National Museum of Natural History, the Institute of Ecology, the Biodiversity and Environment Research Center, the Aquatic Resources Research Center, and the Department of Anthropology of the Americas at the University of Bonn.

New antibiotic for drug-resistant bacteria found hiding in plain sight

Chemists from the University of Warwick and Monash University have discovered a promising new antibiotic that shows activity against drug-resistant bacterial pathogens, including MRSA and VRE.

Antimicrobial resistance (AMR) is one of the world’s most urgent health challenges, with the WHO’s new report showing there are ‘too few antibacterials in the pipeline’. Most of the ‘low-hanging fruit’ has already been found, and the limited commercial incentives deter investment in antibiotic discovery.

In a new study published in the Journal of the American Chemical Society, researchers from the Monash Warwick Alliance Combatting Emerging Superbug Threats Initiative have discovered a promising new antibiotic — pre-methylenomycin C lactone. The newly discovered antibiotic was ‘hiding in plain sight’ – as an intermediate chemical in the natural process that produces the well-known antibiotic methylenomycin A.
