Cell-spanning whirlpools in the immature egg cells of animals such as mice, zebrafish and fruit flies quickly mix the cells' innards, but scientists didn't know how these flows form. Using mathematical modeling, researchers have found an answer. The gyres result from the collective behavior of rodlike molecular tubes called microtubules that extend inward from the cells' membranes, the researchers report.

 E-Mail Credit: Delaneau Group Thousands of genetic markers have already been robustly associated with complex human traits, such as Alzheimer's disease, cancer, obesity, or height. To discover these associations, researchers need to compare the genomes of many individuals at millions of genetic locations or markers, and therefore require cost-effective genotyping technologies. A new statistical method, developed by Olivier Delaneau's group at the SIB Swiss Institute of Bioinformatics and the University of Lausanne (UNIL), offers game-changing possibilities. For less than $1 in computational...

Machine learning can be an effective tool to set competitive prices. Artificial intelligence has its limits on how to set the most effective prices due to variables beyond the seller's control. Over the long term, supracompetitive pricing can result. CATONSVILLE, MD, January 12, 2021 - Machine learning and artificial intelligence (AI) are perfectly suited to help companies and marketers monitor and set prices based on real-time dynamic pricing. But new research has identified some possible unintended consequences of AI in this area. Machine learning algorithms don't always account for factors...

 E-Mail We are fascinated by machines that can control cars, compose symphonies, or defeat people at chess, Go, or Jeopardy! While more progress is being made all the time in Artificial Intelligence (AI), some scientists and philosophers warn of the dangers of an uncontrollable superintelligent AI. Using theoretical calculations, an international team of researchers, including scientists from the Center for Humans and Machines at the Max Planck Institute for Human Development, shows that it would not be possible to control a superintelligent AI. The study was published in the Journal of Art...
