Allie, an AI chess bot, learns to play like humans from 91 million Lichess games

Yiming Zhang didn’t grow up playing chess. Like many other people, the Carnegie Mellon University Ph.D. student discovered the Netflix series “The Queen’s Gambit” during the pandemic and began playing online. However, he quickly realized how unnatural it felt playing against chess bots.

“After I learned the rules, I was in the bottom 10%, maybe 20% of players online,” said Zhang, who is part of the Language Technologies Institute (LTI) in CMU’s School of Computer Science. “For beginners, it’s not interesting or instructive to play against chess bots because the moves they make are often bizarre and incomprehensible to humans.”

Zhang’s frustration led him to develop Allie, a chess bot powered by that demonstrates the benefits of AI tools that think like humans. He believes training future AI systems to ponder and deliberate on could create better agents for use in therapy, education and medicine.

Scientists Create New Magnetic State: The Magneto-Ionic Vortex (“Vortion”)

Researchers at the Universitat Autònoma de Barcelona (UAB) have successfully created a new form of magnetic state known as a magneto-ionic vortex, or “vortion.” Their findings, published in Nature Communications, demonstrate an unprecedented ability to control magnetic properties at the nanoscale under normal room temperature conditions. This achievement could pave the way for next-generation magnetic technologies.

As the growth of Big Data continues, the energy needs of information technologies have risen sharply. In most systems, data is stored using electric currents, but this process generates excess heat and wastes energy. A more efficient approach is to control magnetic memory through voltage rather than current. Magneto-ionic materials make this possible by enabling their magnetic properties to be adjusted when ions are inserted or removed through voltage polarity changes. Up to now, research in this field has mainly focused on continuous films, instead of addressing the nanoscale “bits” that are vital for dense data storage.

At very small scales, unique magnetic behaviors can appear that are not seen in larger systems. One example is the magnetic vortex, a tiny whirlpool-like magnetic pattern. These structures play an important role in modern magnetic data recording and also have biomedical applications. However, once a vortex state is established in a material, it is usually very difficult to modify or requires significant amounts of energy to do so.

NASA Probe Could Intercept Interstellar Comet, Scientists Say

Astronomers at the Pan-STARRS Observatory in Hawaii made history in 2017 when they detected ’Oumuamua, the first interstellar object (ISO) ever observed.

Two years later, the interstellar comet 2I/Borisov became the second ISO ever observed. And on July 1st, 2025, the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Rio Hurtado detected a third interstellar object in our Solar System, the comet now known as 3I/ATLAS (or C/2025 N1 ATLAS).

Like its predecessors, the arrival of this object has fueled immense scientific interest and led to proposals for missions that could rendezvous with future ISOs.

Dementia-like protein buildup found in pancreas cells before cancer develops

Scientists have uncovered dementia-like behavior in pancreas cells at risk of turning into cancer. The findings provide clues that could help in the treatment and prevention of pancreatic cancer, a difficult-to-treat disease linked to 6,900 deaths in the UK every year.

The research was published in the journal Developmental Cell in a paper titled “ER-phagy and proteostasis defects prime pancreatic epithelial state changes in KRAS-mediated oncogenesis.”

Researchers from the Cancer Research UK Scotland Center studied pancreas cells in mice over time, to see what was causing healthy cells to turn into cancer cells. They discovered that at risk of becoming cancerous, known as pre-cancers, develop faults in the cell’s recycling process (known as “autophagy”).
