<p>Opera singers have to use the extreme limits of their voice range. Many pedagogical and scientific sources suggest that the highest pitches reached in classical singing can only be produced with a so-called 'whistle' voice register, in analogy to ultrasonic vocalizations of mice and rats. An international research team has now rejected this assumption. In their study, the scientists showed that the high-frequency sounds of operatic sopranos are produced with the same principle than speech and most other forms of singing.</p>

<p>Cumulative culture -- the accumulation of technological modifications and improvements over generations -- allowed humans to adapt to a diversity of environments and challenges. But, it is unclear when cumulative culture first developed during hominin evolution. A new study concludes that humans began to rapidly accumulate technological knowledge through social learning around 600,000 years ago.</p>

<p>Researchers analyzed 4,400 cognitively unimpaired adults with amyloid imaging, finding increased amyloid in those who reported that their mothers had symptoms of Alzheimer's disease (AD). Increased amyloid, a biomarker of AD, was also found in those with a history of the disease on both sides of their family and in those whose fathers had an early onset of symptoms. The study suggests that a person's maternal versus paternal family history could have a different impact on risk of accumulating amyloid in the brain.</p>

<p>Scientists have proposed a new AI method in which systems of habitual and goal-directed behaviors learn to help each other. Through computer simulations that mimicked the exploration of a maze, the method quickly adapts to changing environments and also reproduced the behavior of humans and animals after they had been accustomed to a certain environment for a long time. The study not only paves the way for the development of systems that adapt quickly and reliably in the burgeoning field of AI, but also provides clues to how we make decisions in the fields of neuroscience and psychology.</p>

<p>A study has revealed a link between gut microbiota and Parkinson's disease. The researchers discovered a decrease in bacterial genes related to the synthesis of vitamins B2 and B7. The lack of these genes was associated with reduced intestinal short-chain fatty acids and polyamines, agents that maintain the intestinal barrier and prevent the leakage of toxins into the blood that can then access the brain. Using B vitamin therapy to address these deficiencies may restore the barrier and treat Parkinson's disease.</p>

<p>Brain-computer interfaces or BCIs hold immense potential for individuals with a wide range of neurological conditions, but the road to implementation is long and nuanced for both the invasive and noninvasive versions of the technology. Scientists have now successfully integrated a novel focused ultrasound stimulation to realize bidirectional BCI that both encodes and decodes brain waves using machine learning in a study with 25 human subjects. This work opens up a new avenue to significantly enhance not only the signal quality, but also, overall nonivasive BCI performance by stimulating targeted neural circuits.</p>
