Physicists at the ARC Centre for Transformative Meta-Optical Systems (TMOS) have fabricated a new way to make wire-grid polarisers at a fraction of the cost of current options on the market – using an ordinary sheet of aluminium kitchen foil and a nanosecond laser with precisely controlled pulses.

Researchers from the University of Osaka have developed a new class of chiral semiconducting polymers that can generate highly spin-polarized electrical currents. The team’s unique molecular design allows the polymers to self-assemble into helical structures that efficiently filter electron spins, offering a promising platform for future spintronic devices and clean-energy technologies.

- Developed a new multilayer interlayer dielectric — an "oxygen tunnel" — that resolves the long-standing trade-off between healing oxygen vacancies and preventing electrode oxidation in oxide vertical channel transistors, achieving world-class current density and stability

- Expected to accelerate the commercialization of next-generation compute-in-memory systems, enabling AI semiconductors process massive amounts of data faster while consuming less power

In a study published on August 19 in Science Translational Medicine, Columbia Engineering professor Gordana Vunjak-Novakovic and her team report the development of a multi-organ chip that mimics how cancer cells spread from vascular flow to distant organs, the first model of cancer metastasis of its kind.

Social media and other technologies have extended gender-based violence in Sub-Saharan Africa into the digital space, including cyber-bullying, stalking and revenge porn, with significant impact on victims
