At the Microsoft Research lab in Tokyo, research intern Lilika Makabe found opportunities to grow her expertise while helping to shape a new research community.
Makabe joined the lab with a background in computer vision and worked alongside researchers exploring robotics and physical intelligence, AI systems that can interpret information and act in the physical world.
Her experience highlights how research internships can offer more than technical training. Through hands-on experimentation, interdisciplinary collaboration, and everyday conversations with colleagues from different backgrounds, Makabe expanded her research perspective while contributing to the lab’s growing community.
You can read about her experience on the Microsoft Research blog.

Breaking the language barrier with AI
For decades, science fiction has imagined a world where language barriers no longer stand in the way of communication.
For example, in 1967, Star Trek introduced the fictional Universal Translator. Now, advances in AI are bringing that possibility closer to reality.
In a new conversation, Microsoft Applied Science Manager Jinyu Li explores how AI is advancing the prospect of communication across languages, the progress researchers have made, and the challenges that remain.

Solving a 31-year-old mathematics challenge
For the last 31 years, the KLS conjecture has been one of the central open problems in high-dimensional geometry. But not anymore.
New research has resolved the conjecture. This removes a major theoretical obstacle to understanding the efficiency of randomized algorithms used across science and computing.
The breakthrough establishes a universal principle for log-concave distributions: simple flat cuts can identify their narrowest bottlenecks within a fixed factor, regardless of dimension. The results have been independently validated, and the proof has also been formally verified using computer-assisted methods.

Making AI coding agents more efficient
Coding agents can help when writing and modifying code, but long sessions can max out the amount of information an AI model can process at once. As a result, coding agents will summarize earlier interactions in a resource-intensive process known as context compaction.
A new study looked at 13.5 million coding sessions and found fewer than 8% required context compaction. Yet those sessions accounted for 44% of total AI processing costs.
To address this challenge, researchers developed COMPACTIONBENCH.
COMPACTIONBENCH is a benchmark for evaluating context compaction during long-running coding tasks. They also introduced APEC, a method that prepares summaries in the background instead of interrupting an agent’s work.
In evaluations, APEC improved coding performance while reducing costs by up to 25.4% and execution time by 9.6%.

Improving AI tokenization across 104 languages
Before AI models can process text, they break it into smaller units called tokens. How that text is divided can affect both efficiency and performance, especially across different languages.
Most tokenizers are designed to compress text as efficiently as possible. But a new study suggests that compression alone isn’t enough.
Researchers introduced the Latent Core Tokenizer, or LCT, which identifies reusable components of words before building a shared vocabulary across languages.
In evaluations spanning 104 languages, LCT produced more linguistically meaningful tokens than leading alternatives while maintaining comparable efficiency across languages. It also improved model performance across four multilingual benchmarks.
The findings suggest that better tokenization depends not just on how much text can be compressed, but on how well the underlying structure of language is preserved.
