Washable Fiber Computer Could Transform the Future of Smart Clothing, Study Finds

A flexible fibre that can be a little smarter than you would like. Scientists have packed computing power into a flexible fibre the width of a cotton thread that can be washed and dried without damage. Described in Nano-Micro Letters, the advance means that clothes will now have a way to keep a check on a wearer's body temperature, retaining the body's warmth in cold conditions and serving as a personal cooling system in hot weather. The fibres contain capabilities for sensing, communication, storage, and computation. The team will need to scale up the technology to create a fabric-based computer network, and imagine wearables that monitor your health, or displays you can play around with, but it's a cool step forward.

Stretchable Fiber Computers Achieve 95% Accuracy in Motion Tracking Tests

According to the study, each elastic fibre is stretchable by up to 60% and embeds eight devices, including four sensors, a photodetector, temperature sensor, accelerometer, and photoplethysmogram sensor, alongside a microcontroller, communication modules, and power management.

For a test of the gadget, developed by the Swiss university ETH Zürich, four fibres were sewn to a piece of clothing, and full wearers carried out bodyweight exercises such as squats and planks. One fiber could pick up motion with 67 percent accuracy; with four fibres, the accuracy jumped to 95 percent.

In order to enhance MFCS, we have developed a multi-fibre online sensing system, where the fibres are organised to work as a team for collaborative sensing. The uploading sections of information include multiple trained neural networks specialised in biosignal analysis and the coordination of the multiple fibres working towards the online human-centric recognition.

The study zeroed in on the system's accuracy but also highlighted its limitations, and it ended with a to-do list for work that remains to be done to improve the speed of communication, lower energy use, and develop lower-latency protocols for fibre-based computing.

Scientists have created wearable technology that allows devices to be computer-controlled at the fibre level, paving the way for use in applications such as personal health monitoring and sports performance.

Hubble Uncovers Multi-Age Stars in Ancient Cluster, Reshaping Galaxy Origins

Astronomers call ancient star clusters like NGC 1786 “time capsules” for their galaxy, preserving some of its oldest stars. A new image from NASA's Hubble Space Telescope offers an unprecedented close-up of this dense cluster 160,000 light-years away in the Large Magellanic Cloud. Hubble's data show that NGC 1786 contains stars of different ages – a surprising find, since such clusters were once thought to hold a single stellar generation. This multi-age discovery is reshaping our view of how galaxies built their first stars, and suggests more complex early history. Mixed-Age Stars in a Galactic Time Capsule According to the official source, this Hubble image shows the globular cluster NGC 1786, a ball of densely packed stars in the Large Magellanic Cloud about 160,000 light-years from Earth. Astronomers captured this picture as part of a program comparing ancient clusters in nearby dwarf galaxies (like the LMC) with clusters in our own Milky Way. The surprising discovery is th...

CSIRO Uses Quantum AI to Revolutionize Semiconductor Design

Researchers at Australia's CSIRO have achieved a world-first demonstration of quantum machine learning in semiconductor fabrication. The quantum-enhanced model outperformed conventional AI methods and could reshape how microchips are designed. The team focused on modeling a crucial—but hard to predict—property called “Ohmic contact” resistance, which measures how easily current flows where metal meets a semiconductor. They analysed 159 experimental samples from advanced gallium nitride (GaN) transistors (known for high power/high-frequency performance). By combining a quantum processing layer with a final classical regression step, the model extracted subtle patterns that traditional approaches had missed. Tackling a difficult design problem According to the study, the CSIRO researchers first encoded many fabrication variables (like gas mixtures and annealing times) per device and used principal component analysis (PCA) to shrink 37 parameters down to the five most important ones. ...

A Planet with a Death Wish: How HIP 67522 b Is Forcing Its Star to Explode

Scientists have caught a planet with a death wish, which is an alien world, orbiting very near to its star, and so speedy that it is causing the star to go to its death with bursting explosions. HIP 67522 b is the planet, and it is of the same size as Jupiter with a seven-day orbit around its host star. These orbits are disturbing the magnetic field of the star and causing enormous blasting eruptions to blow back the planet and make it wrinkled. This is the first time that a planet is influencing the host star, as the astronomers reported in a study published on July 2, 2025, in the Journal Nature. A Planet with a Death Wish: HIP 67522 b's Fiery Orbit As per the study by NASA, Ekaterina Ilin, the first author of the study and an astrophysicist at the Netherlands Institute for Radio Astronomy, said that the planet was observed to trigger the energetic flares. It has been predicted by the scientists that the waves are setting off explosions that are going to happen. Magnetic Chaos: P...
