Bill Gates worries that kids today may miss out on a key advantage he had. The billionaire credits his successful career, in part, to having the freedom, and free time, in his youth to explore the world around him, to read and to think deeply without more modern distractions like smartphones and social media.

Today’s kids spend less time outside, exploring and playing with friends, than previous generations, thanks to the ubiquity of smartphones and social media.

That switch from a “play-based childhood” to one that’s “phone-based” has triggered a cultural shift that’s behind rising rates of mental health issues in younger generations, along with other negative effects on kids’ ability to learn and socialize, according to social psychologist Jonathan Haidt’s 2024 best-selling book “The Anxious Generation.”

Imagine a future where your phone, computer or even a tiny wearable device can think and learn like the human brain—processing information faster, smarter and using less energy.

A new approach developed at Flinders University and UNSW Sydney brings this vision closer to reality by electrically “twisting” a single nanoscale ferroelectric domain wall.

The domain walls are almost invisible, extremely tiny (1–10 nm) boundaries that naturally arise or can even be injected or erased inside special insulating crystals called ferroelectrics. The domain walls inside these crystals separate regions with different bound charge orientations.

A team of metallurgists and geochemists at Guangzhou Institute of Geochemistry, working with a mechanical engineer from the Chinese Academy of Sciences, has improved their previous electrokinetic mining technique by scaling it up to industrial levels. In their paper published in Nature Sustainability, the group describes the changes they made to their system, and the results of testing they conducted at a mine.

Modern technology is reliant on multiple —they are used in EVs, smartphones and computers, for example. Unfortunately, mining such elements is extremely environmentally unfriendly. Huge machines are used to dig dirt and rock from large mines, where it is mixed with water and a host of toxic chemicals in order to extract the desired elements.

The process produces thousands of metric tons of toxic waste. The team in China has been working for several years to develop a cleaner way to extract the elements. It involves generating an electric field underground that coaxes the desired elements closer together and concentrates them, making for a much easier and cleaner separation process.

“Nowadays we always have our mobile phones or a flashlight, but to see bioluminescence in the forest, it has to be pitch black,” said Rudolf.

They collected some samples of the glowing specimen, originally thinking it was a known bioluminescent species called Mycena haematopus. In their well-lit studio, the artists realized that it was another species called the saffron drop bonnet mushroom (Mycena crocata). While this mushroom is known for its saffron-coloured milk, it had not previously been described as bioluminescent.

It was easy to miss Dr. Robert Gray’s quick movements, tapping the screen of his smartphone at the beginning and end of patient visits on a recent day.

But Gray said those fast finger taps have changed his life. He was tapping an app that records discussions during his appointments and then uses to find the relevant information, summarize it and zap it, within seconds, into each patient’s electronic medical record.

The technology was meticulously documenting each visit so Gray didn’t have to.

Scientists at EPFL achieved a breakthrough by synchronizing six mechanical oscillators into a collective quantum state, enabling observations of unique phenomena like quantum sideband asymmetry. This advance paves the way for innovations in quantum computing and sensing.

Quantum technologies are revolutionizing our understanding of the universe, and one promising area involves macroscopic mechanical oscillators. These devices, already integral to quartz watches, mobile phones, and telecommunications lasers, could play a transformative role in the quantum realm. At the quantum scale, macroscopic oscillators have the potential to enable ultra-sensitive sensors and advanced components for quantum computing, unlocking groundbreaking innovations across multiple industries.

Achieving control over mechanical oscillators at the quantum level is a critical step toward realizing these future technologies. However, managing them collectively poses significant challenges, as it demands nearly identical units with exceptional precision.
