You might be older -- or younger -- than you think. A new study found that differences between a person's age in years and his or her biological age, as predicted by an artificial intelligence (AI)-enabled EKG, can provide measurable insights into health and longevity. The AI model accurately predicted the age of most subjects, with a mean age gap of 0.88 years between EKG age … [Read more...] about AI-enabled EKGs find difference between numerical age and biological age significantly affects health

Middle-school aged children who use the internet, social media or video games recreationally for more than an hour each day during the school week have significantly lower grades and test scores, according to a study from the Center for Gambling Studies at Rutgers University-New Brunswick. The findings appear in the journal Computers in Human Behavior. Researchers say the … [Read more...] about Young teens should only use recreational internet and video games one hour daily: New research finds test scores, educational aspirations drop if children overuse non-educational technology

Archaeologists at Northern Arizona University are hoping a new technology they helped pioneer will change the way scientists study the broken pieces left behind by ancient societies. The team from NAU's Department of Anthropology have succeeded in teaching computers to perform a complex task many scientists who study ancient societies have long dreamt of: rapidly and … [Read more...] about Archaeologists teach computers to sort ancient pottery

Alzheimer's disease shares some key similarities with healthy aging, according to a new mathematical model described today in eLife. The model provides unique insights into the multiscale biological alterations in the elderly and neurodegenerative brain, with important implications for identifying future treatment targets for Alzheimer's disease. Researchers developed their … [Read more...] about Scientists map gene changes underlying brain and cognitive decline in aging

Scientists have developed a mathematical model that predicts how the number and effects of bacterial mutations leading to drug resistance will influence the success of antibiotic treatments. Their model, described today in the journal eLife, provides new insights on the emergence of drug resistance in clinical settings and hints at how to design novel treatment strategies that … [Read more...] about Mathematical model predicts effect of bacterial mutations on antibiotic success

The field of mathematical topology is often described in terms of donuts and pretzels. To most of us, the two differ in the way they taste or in their compatibility with morning coffee. But to a topologist, the only difference between the two is that one has a single hole and the other has three. There's no way to stretch or contort a donut to make it look like a pretzel -- at … [Read more...] about Researchers use ‘hole-y’ math and machine learning to study cellular self-assembly

Artificial intelligence is providing new opportunities in a range of fields, from business to industrial design to entertainment. But how about civil engineering and city planning? How might machine- and deep-learning help us create safer, more sustainable, and resilient built environments? A team of researchers from the NSF NHERI SimCenter, a computational modeling and … [Read more...] about Envisioning safer cities with AI: Researchers use crowdsourced data, neural networks, and supercomputers to simulate risks to cities and regions

The rhythmic motions of hair-like cilia move liquids around cells or propel the cells themselves. In nature, cilia flap independently, and mimicking these movements with artificial materials requires complex mechanisms. Now, researchers reporting in ACS Applied Materials & Interfaces have made artificial cilia that move in a wave-like fashion when a rotating magnetic field … [Read more...] about Magnetically propelled cilia power climbing soft robots and microfluidic pumps

Due to climate change, the average global temperature will rise in the coming decades. This should also significantly increase the number of so-called cooling degree days. These measure the number of hours, in which the ambient temperature is above a certain threshold, at which a building must be cooled to keep the indoor temperature at a comfortable level. The rising values … [Read more...] about Rising energy demand for cooling: Keeping it cool despite climate change

An artificial intelligence (AI) program accurately predicts the risk that lung nodules detected on screening CT will become cancerous, according to a study published in the journal Radiology. Lung cancer is the leading cause of cancer death worldwide, with an estimated 1.8 million deaths in 2020, according to the World Health Organization. Low-dose chest CT is used to screen … [Read more...] about AI predicts lung cancer risk
