Recent work from the National Centre for Biological Sciences (NCBS), Bangalore, has shown that the regeneration of a signaling molecule, phosphatidylinositol 4,5 bisphosphate (PIP2), is not as simple as it was thought to be. Experimental work from Raghu Padinjat's group and mathematical modelling by Sandeep Krishna's team from the Simons Centre for Living Machines at NCBS shows that the decades-old model of the biochemical cycle may have two unknown steps that could change the way scientists interpret experimental data.
The ability of artificial intelligence to help screen patients for a common diabetic eye disease gains momentum with a new study published online today in Ophthalmology, the journal of the American Academy of Ophthalmology. Lily Peng, M.D., Ph.D., and her colleagues at Google AI research group, show they could improve their disease-detecting software by using a small subset of images adjudicated by ophthalmologists who specialize in retinal diseases.
Richard Sowers, a professor of industrial and enterprise systems engineering and mathematics at the University of Illinois at Urbana-Champaign, and a team of students have developed an algorithm that promises to give valuable information to farmers of crops picked by hand.
Researchers have found that right whale calls, much like human voices, change as individuals age. In a study recently published in Animal Behaviour, scientists examined 986 high-quality calls from 49 individual North Atlantic right whales of known ages spanning from 1 month to 37 years. Calls made by whales younger than 1 year were shorter and less structured than adult sounds. As the animals matured their calls became more clear, with better defined structure and longer call durations.
Kyoto University investigates how seemingly separate concepts in scientific fields fuse to become universal approaches by by developing a new methodology to analyze citations in papers that use similar concepts, and tracked the changes over time. The researcher used ABM -- agent based modeling -- and IBM -- individual based modeling as examples.
Three MIT researchers, Soroush Vosoughi and Deb Roy of the Media Lab and Sinan Aral of the Sloan School of Management, investigated all the true and false news stories verified by six independent fact checking organizations that were distributed on Twitter from 2006 to 2017. The researchers found that false news travels farther, faster, deeper and more broadly than the truth online in all categories.
Using data collected by citizen scientists, researchers have developed new, open-source algorithms to automatically detect bat echolocation calls in audio recordings. Oisin Mac Aodha, formerly of University College London, now at Caltech, and colleagues at University College London present their new approach in PLOS Computational Biology.
By employing algorithms and digital imaging, Brazilian researchers design a non-invasive system which performs the tricky task of identifying different stages of fruit ripening with an accuracy rate of 95%.
New research has developed an automated approach for narrowing down and ranking the field of Division 1 college basketball teams from 351 to the 68 that would play in the annual 'March Madness' basketball tournaments, watched by more than 80 million people each year.
Physics modeled a spin diode, placing the device between two kinds of antiferromagnetic materials. Turning those antiferromagnets layers changes the resistance and resonant frequency of sandwich.
