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.
Jets are rapid streams of liquids or gases that forcefully shoot into a surrounding medium. When ignitable substances are involved, combustion--rapid chemical reactions that result in heat and light--can occur. Autoignition ensues when this spontaneous combustion results in a visible flame. In a newly-published paper, authors provide a mathematical model for autoignition in free round turbulent jets.
Renowned international scientists have presented first-level research results on the intersection of embedded systems and wireless networks at the EWSN 2018 conference. The international event covered a wide range of topics going from energy constrained applications, security, emerging networking paradigms and protocols to distributed computing and cyber physical systems. Special emphasis was put on the reduction of the carbon footprint that the increasing use of ICT technologies imposes on the planet.
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.
In 2016 voters in the US and the UK defied expert predictions with the Vote Leave campaign winning for the UK to leave the European Union (Brexit) and the election of President Donald Trump. A world-first QUT-led study reveals why and how fear may now be driving the global political landscape.
St. Jude Children's Research Hospital scientists have developed a new method to measure social networks of survivors of adolescent and young adult cancer in order to cultivate the health benefits of social connections
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.
