Credit: PixabayBreaking a Six-Year Drought in Prime DiscoveriesA recent participant in the Great Internet Mersenne Prime Search (GIMPS) has broken a six-year stretch without new discoveries in the quest for large prime numbers, among the usual composites.This new prime number has an impressive 41,024,320 decimal digits—it would take months to write out in full....
Concept of the Airbus/Toshiba superconducting aircraft motorCollaboration for Ultra-Efficient Motor DevelopmentAirbus and Toshiba have joined forces to develop an ultra-efficient superconducting motor for aircraft that utilizes liquid hydrogen to power the propulsion system and cool adjacent systems.Among the alternatives for reducing aircraft emissions, hydrogen stands out for its high energy density and ability to...
A gynecologist points out that sitting for many hours with equipment that generates heat, such as a laptop, causes the temperature inside the scrotum to rise. Credit: compumake,The Covid-19 pandemic brought significant societal changes, including a rise in remote work. Many professionals, especially men, have continued to work from home in various countries. However,...

ThilkerThe NASA/ESA Hubble Space Telescope has unveiled a new mesmerizing image of the spiral galaxy Messier 90 (M90) in the constellation Virgo. Originally captured using the Wide Field and Planetary...
The ultrasensitive robot 'finger' can perform routine physical examsUSTC/Hongbo WangResearchers have created an ultrasensitive robotic ‘finger’ that mimics human touch, capable of safely conducting routine physical exams similar to those performed by doctors. They believe this 'robodoctor' could soon appear in medical clinics.Doctors use their fingers as diagnostic tools to gather various insights about...
The hole-digging, seed-bomb-depositing, Plantolin pangolin-inspired robotUniversity of SurreyForaging pangolins naturally dig in the ground, so why not have them plant trees at the same time? Training them to do so would be quite challenging, which is why a high school student from California named Dorothy created a pangolin-inspired robot to handle the digging and...
El Cosmico is an ambitious 3D-printed development that will remake a large chunk of the Texas desert landscape into a campground hotel with vacation homes and starchitect-designed permanent homesIconAfter its earlier reveal this year, leading 3D-printed architecture company Icon is now constructing the ambitious El Cosmico campground hotel in the Texas desert. Touted as...
Morphological features of "Sheba" at different ages. Credit: Communications Biology (2024). DOI: 10.1038/s42003-024-06721-5An international team of botanists, agriculturists, and historians has successfully cultivated a mature tree from an ancient seed discovered in an Israeli cave.In fact, in their study published in Communications Biology, the researchers detail the seed’s origin, the process of tracing its history,...
ABENICS can roll, pitch, and yaw in every directionYamagata UniversityAt its core, this system created at Yamagata University in Japan utilizes a "simple" cross-spherical gear combined with a monopole gear to manage pitch, roll, and yaw. This mimics the full range of motion found in a human rotator cuff (the shoulder). Thanks to innovative...
Magnetic pixels in this little screen are capable of encrypting imagesJeremy Little/Michigan EngineeringResearchers, inspired by the color-changing skin of squids and other cephalopods, have created a flexible screen that stores and displays encrypted images using only magnetic particles, without any electronics.Scientists have been experimenting with metamaterials—engineered materials with unusual properties not found in nature—for...
