A new study by the University of Georgia revealed that more college students change majors within the STEM pipeline than leave the career path of science, technology, engineering and mathematics altogether. Funded by a National Institutes of Health grant and a National Science Foundation Postdoctoral Fellowship and done in collaboration with the University of Wisconsin, the … [Read more...] about New research may explain shortages in STEM careers: The study focuses on students who change plans within the pipeline

People may be reluctant to give their personal information to artificial intelligence (AI) systems even though it is needed by the systems for providing more accurate and personalized services, but a new study reveals that the manner in which the systems ask for information from users can make a difference. In a study, Penn State researchers report that users responded … [Read more...] about How AIs ask for personal information is important for gaining user trust

A new theorem from the field of quantum machine learning has poked a major hole in the accepted understanding about information scrambling. "Our theorem implies that we are not going to be able to use quantum machine learning to learn typical random or chaotic processes, such as black holes. In this sense, it places a fundamental limit on the learnability of unknown processes," … [Read more...] about Quantum machine learning hits a limit

A new discovery led by Princeton University could upend our understanding of how electrons behave under extreme conditions in quantum materials. The finding provides experimental evidence that this familiar building block of matter behaves as if it is made of two particles: one particle that gives the electron its negative charge and another that supplies its magnet-like … [Read more...] about New evidence for electron’s dual nature found in a quantum spin liquid

Artificial intelligence (AI) learning machines can be trained to solve problems and puzzles on their own instead of using rules that we made for them. But often, researchers do not know what rules the machines make for themselves. Cold Spring Harbor Laboratory (CSHL) Assistant Professor Peter Koo developed a new method that quizzes a machine-learning program to figure out what … [Read more...] about Making AI algorithms show their work

A new strategy for capturing the 3D shape of the human face draws on data from sibling pairs and leads to identification of novel links between facial shape traits and specific locations within the human genome. Hanne Hoskens of the Department of Human Genetics at Katholieke Universiteit in Leuven, Belgium, and colleagues present these findings in the open-access journal PLOS … [Read more...] about A sibling-guided strategy to capture the 3D shape of the human face

Obsessive-compulsive disorder (OCD) in children and adolescents is associated with impaired education and worse general health later in life. Access to specialist treatment is often limited. According to a study from Centre for Psychiatry Research at Karolinska Institutet in Sweden and Region Stockholm, internet-delivered cognitive behavioural therapy (CBT) can be as effective … [Read more...] about Online therapy effective against OCD symptoms in the young

You enter a room and quickly scan the crowd to gain a sense of who's there -- how many men versus women. How reliable is your estimate? Not very, according to new research from Duke University. In an experimental study, researchers found that participants consistently erred in estimating the proportion of men and women in a group. And participants erred in a particular way: … [Read more...] about Focus on outliers creates flawed snap judgments: Our quick scan of a crowd isn’t as reliable as we think, new research suggests

Researchers at North Carolina State University have made what is believed to be the smallest state-of-the-art RFID chip, which should drive down the cost of RFID tags. In addition, the chip's design makes it possible to embed RFID tags into high value chips, such as computer chips, boosting supply chain security for high-end technologies. "As far as we can tell, it's the … [Read more...] about Smaller chips open door to new RFID applications

Leipzig/Jena/Ilmenau. Mobile apps like Flora Incognita that allow automated identification of wild plants cannot only identify plant species, but also uncover large scale ecological patterns. These patterns are surprisingly similar to the ones derived from long-term inventory data of the German flora, even though they have been acquired over much shorter time periods and are … [Read more...] about How smartphones can help detect ecological change: Plant occurrence data collected with an app uncovers macroecological patterns in Germany
