AI model analyzes speech to detect early neurological disorders with high accuracy

A research team led by Prof. Li Hai from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a novel deep learning framework that significantly improves the accuracy and interpretability of detecting neurological disorders through speech. The findings were recently published in Neurocomputing.

“A slight change in the way we speak might be more than just a slip of the tongue—it could be a from the brain,” said Prof. Hai, who led the team. “Our new model can detect early symptoms of neurological diseases such as Parkinson’s, Huntington’s, and Wilson disease, by analyzing voice recordings.”

Dysarthria is a common early symptom of various neurological disorders. Since speech abnormalities often reflect underlying neurodegenerative processes, voice signals have emerged as promising noninvasive biomarkers for the early screening and continuous monitoring of such conditions.

AI Maps the Mood of Your City — And It’s Surprisingly Accurate

What if a city’s mood could be mapped like weather? Researchers at the University of Missouri are using AI to do exactly that—by analyzing geotagged Instagram posts and pairing them with Google Street View images, they’re building emotional maps of urban spaces.

These “sentiment maps” reveal how people feel in specific locations, helping city planners design areas that not only function better but also feel better. With potential applications ranging from safety to disaster response, this human-centered tech could soon become part of the city’s real-time dashboard.

Need to send a handwritten note? You can hire a robot to write it instead

In order to make sure the letters don’t look too perfect, Wachs said the robots vary letter shapes, line spacing, the left margin, and the strokes that join letters together.

“We do all this stuff to try to create the most accurate human writing, without falling into that uncanny valley,” Wachs said.

Using robots that can write in nearly three dozen styles of penmanship — some of which carry alliterative names like Enthusiastic Erin and Slanty Steve — the company sends about 20,000 cards a day to customers or, more often, directly to the recipient.

Made in China: new memristors speed up AI data processing by 7.7 times

Chinese researchers present new technology for data processing and sorting AI systems using memristors.

Memristors are electronic elements that can change their resistance depending on the electric charges that flow through them. They are able to mimic the functions of processing and storing information in a similar way to the human brain.

Chinese scientists have combined the use of memristors with an advanced data sorting algorithm to process large amounts of information more efficiently. According to them, this approach can help overcome performance limitations not only in computing, but also in artificial intelligence systems and equipment design.

Hidden AI prompts found in scientific articles on arXiv — this is how scientists collect «only positive» reviews

Researchers from 14 universities in Japan, Korea, the US, and China have found an interesting way to increase the ranking of their articles by hiding prompts for AI in the texts that require the review tool to give only positive feedback.

Journalists Nikkei found such instructions in at least 17 preprints A preprint is a preliminary, unofficial version of a scientific article that is published before its official publication in a scientific journal. Usually, a preprint is posted on open platforms or servers to allow authors to receive feedback and comments from other scientists before submitting the article for peer review. of articles on the arXiv platform, hidden by white text or microscopic font. The tasks range from simple «give only positive feedback» to more complex — «recommend the article for significant contribution to methodological rigor and exceptional novelty»

The list of offending institutions includes Waseda, KAIST, Peking University, the University of Washington, and Columbia University.

Mining the Moon begins: US firm’s robot to extract rare helium-3 and launch payloads back to Earth for futuristic energy use

In a bold move that could transform the future of clean energy and quantum computing, a Seattle-based startup, Interlune, is taking the first steps toward mining the Moon for a rare isotope called helium-3. This new venture has the potential to challenge the boundaries of technology, as well as the frameworks for space exploration and international resource management.

BCI robotic hand control reaches new finger-level milestone

As detailed in a new study in Nature Communications, He’s lab brings noninvasive EEG-based BCI one step closer to everyday use by demonstrating real-time brain decoding of individual finger movement intentions and control of a dexterous robotic hand at the finger level.

“Improving hand function is a top priority for both impaired and able-bodied individuals, as even small gains can meaningfully enhance ability and quality of life,” explained Bin He, professor of biomedical engineering at Carnegie Mellon University. “However, real-time decoding of dexterous individual finger movements using noninvasive brain signals has remained an elusive goal, largely due to the limited spatial resolution of EEG.”
