CRISPR technology allows researchers to edit genomes by altering DNA sequences and by thus modifying gene function. Its many potential applications include correcting genetic defects, treating and preventing the spread of diseases and improving crops. Genome editing tools, such as the CRISPR-Cas9 technology, can be engineered to make extremely well-defined alterations to the … [Read more...] about Accurate evaluation of CRISPR genome editing: Researchers develop a novel software tool to quantify potential CRISPR-induced errors

U.S. and Austrian physicists searching for evidence of quantum criticality in topological materials have found one of the most pristine examples yet observed. In an open access paper published online in Science Advances, researchers from Rice University, Johns Hopkins University, the Vienna University of Technology (TU Wien) and the National Institute of Standards and … [Read more...] about Pristine quantum criticality found: Study: Quantum fluctuations may give rise to topological phases of matter

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
