Researchers outline promises, challenges of understanding AI for biological discovery      (via sciencedaily.com)     Original source 

Machine learning is a powerful tool in computational biology, enabling the analysis of a wide range of biomedical data such as genomic sequences and biological imaging. But when researchers use machine learning in computational biology, understanding model behavior remains crucial for uncovering the underlying biological mechanisms in health and disease. Researchers now propose guidelines that outline pitfalls and opportunities for using interpretable machine learning methods to tackle computational biology problems.

Demographics of north African human populations unravelled using genomic data and artificial intelligence      (via sciencedaily.com)     Original source 

A new study places the origin of the Imazighen in the Epipaleolithic, more than twenty thousand years ago. The research concludes that the genetic origin of the current Arab population of north Africa is far more recent than previously believed, placing it in the seventh century AD. The team has designed an innovative demographic model that uses artificial intelligence to analyze the complete genomes of the two populations.

Researchers explore the potential of clean energy markets as a hedging tool      (via sciencedaily.com)     Original source 

Clean energy investments offer potential stability and growth, especially during volatile market conditions. A recent study explored the relationship between clean energy markets and global stock markets. Significant spillovers were observed from major indices like the SP500 to markets such as Japan's Nikkei225 and Global Clean Energy Index. These interactions suggest opportunities for optimizing investment portfolios and leveraging clean energy assets as hedging tools in volatile market environments.

Space-trekking muscle tests drugs for microgravity-induced muscle impairment      (via sciencedaily.com)     Original source 

A gentle rumble ran under a researcher's feet as a rocket carrying her research -- live, human muscle cells grown on scaffolds fixed on tiny chips -- lifted off, climbed, and disappeared into the sky to the International Space Station National Laboratory. These chips would help her better understand muscle impairment, often seen in astronauts and older adults, and test drugs to counter the condition.
