Tiny tech, big AI power: What are 2-nanometer chips?
Taiwan’s world-leading microchip manufacturer TSMC says it has started mass producing next-generation “2-nanometer” chips.
AFP looks at what that means, and why it’s important:
What can they do? The computing power of chips has increased dramatically over the decades as makers cram them with more microscopic electronic components.
Soft, 3D transistors could host living cells for bioelectronics
New research from the WISE group (Wearable, Intelligent, Soft Electronics) at The University of Hong Kong (HKU-WISE) has addressed a long-standing bioelectronic challenge: the development of soft, 3D transistors.
This work introduces a new approach to semiconductor device design with transformative potential for bioelectronics. It is published in Science.
Led by Professor Shiming Zhang from the Department of Electrical and Electronic Engineering, Faculty of Engineering, the research team included senior researchers who joined HKU-WISE from the University of Cambridge and the University of Chicago, together with HKU Ph.D. students and undergraduate participants—an international, inclusive, and dynamic research community.
Neutral-atom arrays, a rapidly emerging quantum computing platform, get a boost from researchers
For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian Will and Nanfang Yu have their sights set much higher.
“We are laying critical groundwork to enable quantum computers with more than 100,000 qubits,” Will said.
In a paper published in Nature, Will, Yu, and their colleagues combine two powerful technologies— optical tweezers and metasurfaces—to dramatically scale the size of neutral-atom arrays.
Familial Hypercholesterolemia Screening in Childhood and Early Adulthood: A Cost-Effectiveness Study
Sequential childhood or early adulthood screening for familial hypercholesterolemia may lower lifetime CVD risk, but is unlikely to be cost-effective unless ongoing follow-up for elevated cholesterol is widely implemented.
This study uses a computer model to estimate the cost-effectiveness of sequential familial hypercholesterolemia screening at age 10 or 18 years using 3 low-density lipoprotein cholesterol (LDL-C) thresholds.
裂 The Virus That Rewrote Its Own Rulebook: What D1.1 Teaches Us About Living in an Evolving World
Bird Flu 2026
Researchers analyzed 17,500 genomes using Bayesian phylodynamics. Mapped origin, spread, and evolutionary timeline with precision.
The infrastructure failure: Of 1,722 D1.1 sequences, 9% have complete metadata (date + location).
We’re tracking a super-spreader blind.

“Avian Flu in North America: The D1.1 Evolutionary Leap” explores the emergence of a game-changing H5N1 virus variant that has fundamentally altered North America’s disease landscape since mid-2024. Through accessible explanation of cutting-edge genomic science, this episode reveals how the D1.1 genotype achieved unprecedented spread, infected all seven documented host categories including humans, and represents a major evolutionary shift. The podcast examines the massive computational effort behind tracking viral evolution, exposes critical gaps in our surveillance infrastructure, and confronts a paradigm-shifting reality: the Americas have become a primary engine of H5N1 evolution, reversing decades of global health assumptions.
An earthquake on a chip: New tech could make smartphones smaller, faster
A team of engineers has made major strides in generating the tiniest earthquakes imaginable. The team’s device, known as a surface acoustic wave phonon laser, could one day help scientists make more sophisticated versions of chips in cellphones and other wireless devices—potentially making those tools smaller, faster and more efficient.
The study was conducted by Matt Eichenfield, an incoming faculty member at the University of Colorado Boulder, and scientists from the University of Arizona and Sandia National Laboratories. The researchers published their findings in the journal Nature.
The new technology utilizes a phenomenon known as surface acoustic waves, or SAWs act a little like soundwaves, but, as their name suggests, they travel only on the top layer of a material.

First standalone spin-wave chip operates without external magnets for future telecom
The Politecnico di Milano has created the first integrated and fully tunable device based on spin waves, opening up new possibilities for the telecommunications of the future, far beyond current 5G and 6G standards. The study, published in the journal Advanced Materials, was conducted by a research group led by Riccardo Bertacco of the Department of Physics of the Politecnico di Milano, in collaboration with Philipp Pirro of Rheinland-Pfälzische Technische Universität and Silvia Tacchi of Istituto Officina dei Materiali—CNR-IOM.
Magnonics is an emerging technology that uses spin waves —collective excitations of electronic spins in magnetic materials—as an alternative to electrical signals. The spread of this technology has been restricted until now by the need for an external magnetic field, which has prevented it being incorporated into chips.
The new device developed at the Politecnico overcomes this hurdle: it is miniaturized (100 × 150 square micrometers, so much smaller than current radiofrequency signal processing devices based on acoustic waves); it is fully integrated on silicon—and therefore compatible with existing electronic platforms, and it functions without external magnets, thanks to an innovative combination of permanent SmCo micromagnets and magnetic flux concentrators.
