A group of scientists from the Institute of Science Tokyo has developed an innovative material that utilizes molecular rotors for information storage, marking a significant step forward in microelectronics. This discovery, published in the Journal of the American Chemical Society, could pave the way for a new era of non-volatile memories, like ROMs, capable of storing data at densities that far exceed what current semiconductor technologies can achieve.

The Concept Behind Molecular Rotors

This new system incorporates small molecules called “molecular rotors,” which can be rotated in various directions to signify bits of information. Researchers have been attempting to create such a solution for a long time, but they have faced difficulties in addressing four essential requirements simultaneously.

Innovative Design Approach

The research team, spearheaded by Professor Yoichi Murakami, tackled these challenges by developing a Covalent Organic Framework (COF) featuring an extremely low-density crystal structure. This one-of-a-kind structure, previously unrecorded in COFs, allows the molecular rotors to rotate freely when an electric field is applied while maintaining stability at normal temperatures.

“This is a breakthrough, because our COFs are a rare solid in which dipolar rotors can flip when they are brought to elevated temperatures above 200 °C or undergo sufficiently strong electric fields, but their orientations can be held for a long time at ambient temperatures,” says Professor Yoichi Murakami.

Thermal Stability and Future Implications

The researchers also found that the material possesses thermal durability close to 400 °C. Although it might take several years before this technology is implemented in consumer devices, it has opened avenues for future exploration. Someday, we might see digital storage units with far greater density than what is available today, enabling more data to be stored in less physical space.

The end of support for Windows 10 is getting close. There are still many laptops that are over seven years old and function just fine. We looked through our records to find a laptop from 2018 and compared it with a budget-friendly model from 2025: the Acer Aspire Go 15.

Comparison Device

Our device for comparison is the Toshiba Tecra A50-E-110, which is just about able to run Windows 11. It features an 8th-generation Intel Core i5 processor. This performance is still good enough for tasks like office work, checking emails, and browsing the web. The laptop is sturdy and includes USB 3.0 ports, plus it can even fit a DVD drive.

Processor Compatibility

The processor in the Toshiba is one of the earliest Intel models that can work with Windows 11. Laptops with older Kaby Lake processors and earlier will not officially get Windows 11, so owners will need to find other options if updating to a new operating system isn’t possible.

That being said, the most affordable, safest, and eco-friendly choice is to revitalize old hardware with a new OS. Lightweight systems like ChromeOS Flex or user-friendly Linux distributions can be easily installed on many older machines, turning them into secure and efficient devices for daily tasks. This method requires a bit of trial and error, but it’s kinder to both your finances and the planet. We have detailed this process in another article. Linux Mint makes it especially simple since it incorporates many design features from Windows 11. ChromeOS Flex, in contrast, might take some time to get used to.

New Purchases

For those who prefer a simple solution without the need for adjustments, buying a new laptop is often necessary. This is where our recently reviewed Acer Aspire Go 15 becomes relevant. Priced at under $600, it’s a very appealing choice for an upgrade. But does it improve on all fronts?

The older Tecra laptop has features like an optional DVD drive (which might be seen as outdated for some) and a built-in card reader, but these can be easily added to new laptops. A small docking station featuring a card reader, VGA ports, and extra USB ports is available for under $40 on Amazon.

In terms of performance, the Aspire Go is definitely the more powerful laptop. Websites and applications load significantly quicker, the latest Wi-Fi technology ensures reliable connections, and the reasonably modern Intel processor should support several years of Windows usage. A direct comparison of benchmark results between the two machines highlights a clear disparity in performance.

Conclusion

Regardless of the option you go for, an old but still working laptop is too precious to be discarded as e-waste. Organizations like the nonprofit Labdoo.org welcome such devices as donations. Volunteers refurbish these laptops and provide them a valuable second life in schools around the globe. This way, your long-time companion can still contribute positively, even without Windows support. Before you do this, however, make sure to back up and/or erase all data from your old device.

A powerful 1,000-ton particle detector named sPHENIX has passed a crucial test, demonstrating its readiness for its main goal — investigating the beginnings of the universe. This detector, situated at the Brookhaven National Laboratory’s Relativistic Heavy Ion Collider, is specially designed to accurately assess the aftermath of rapid particle collisions, aiming to recreate the characteristics of quark-gluon plasma.

Understanding Quark-Gluon Plasma

Quark-gluon plasma is a superheated mixture of subatomic particles thought to have existed for a mere few microseconds after the Big Bang, before it cooled and formed the protons and neutrons we recognize today.

Testing and Results

To evaluate the accuracy and speed of this new particle detector, researchers conducted a standard candle test. They collided gold ions nearly at light speed while gathering data. The findings, published in the Journal of High Energy Physics, confirmed that sPHENIX met expectations, accurately measuring the number of charged particles generated during the collisions. It even revealed that direct collisions produced 10 times more particles and 100 times more energy compared to glancing collisions.

“It’s like you’ve sent a brand new telescope into space after spending a decade crafting it, and it captures its first image. It may not showcase something entirely new, but it assures us that it’s primed to embark on new scientific journeys.” — Gunther Roland, a physics professor at MIT and a participant in the sPHENIX Collaboration.

Features of the sPHENIX Detector

The sPHENIX detector is a state-of-the-art device comparable in size to a two-story house, capable of measuring up to 15,000 collisions every second. This rapidity enhances research as rare events can be observed more often. When operational, it could assist scientists in exploring the characteristics of the early universe.

A team of scientists at CU Boulder has made a significant advancement by developing the first time crystal visible to the naked eye. This breakthrough brings a strange form of matter into the physical realm, paving the way for innovative technologies. The researchers employed liquid crystals, the same substance found in LCD screens, to achieve this milestone.

Understanding Time Crystals

Time crystals represent an unusual state of matter — first proposed by Nobel Prize winner Frank Wilczek in 2012 — where particles maintain a continuous cycle of motion, even when at rest, similar to a clock that operates indefinitely without needing a power source. While microscopic time crystals have been produced using quantum computers, the CU Boulder creation is the first that can be directly observed.

The Research Team’s Methodology

The group, which includes Professor Ivan Smalyukh and graduate student Hanqing Zhao, accomplished this feat by placing a liquid crystal solution between two glass panels coated in dye. When exposed to a specific type of light, the dye molecules compressed the liquid crystals, leading to the formation of thousands of new kinks.

These kinks began to move and interact in intricate repeating patterns that could persist for hours. The patterns showed impressive resilience to outside influences, remaining unchanged even when the researchers altered the temperature.

Potential Applications

The researchers believe their invention could have multiple uses in daily life, highlighting two specific possibilities. One application is creating a “time watermark” on banknotes, allowing people to verify the authenticity of currency simply by shining light on it and observing the resulting patterns. Additionally, they propose that stacking different time crystals could generate extremely complex patterns, which might be utilized for data storage.
