Almost 1 in 5 Indian adults aged 60+ show signs of mild neurocognitive disorder, according to a study.

Given an estimated 138 million adults over 60 years of age in India, these estimates suggest approximately 24 million and 9.9 million older adults in India are living with mild and major neurocognitive disorder, respectively, revealed the study published in the journal PLOS One.

Summary: A new study illuminated how fruit flies navigate by revealing the communication between their internal compass and steering brain regions. This study shows that three distinct neuron groups translate directional signals into corrective actions, allowing fruit flies to adjust their course effectively.

These findings not only deepen our understanding of navigation in simpler organisms but also lay the groundwork for future research into the neural basis of behavior in more complex species, including humans.

By exploring the intricacies of fruit fly brains, scientists have uncovered fundamental principles of cognitive processing and behavior adjustment, offering insights into how internal cognitive states like direction sense are converted into tangible actions.

Extracting lithium from California’s Salton Sea for use in batteries.

California’s toxic Salton Sea has enough lithium to make the U.S. self-sufficient in the mineral, which is a key component of rechargeable batteries. WSJ explores the tech being developed to extract it—and what it means for the future of domestic production. Photo: Kaitlyn Wang.

A team of researchers from Carnegie Mellon University has successfully developed a new program that enables robots to learn how to open doors independently.

A robot that can learn to open most types of doors, cabinets, drawers and refrigerators – without human direction – may pave the way for your future robot butler.
