New Method Maps Contact Points Between Replicated DNA Molecules
News Sep 24, 2020Breaks in our DNA, which can occur spontaneously or result from irradiation or chemical insults, can lead to severe problems since they foster mutations and can ultimately lead to cancer. One of the main DNA repair pathways involves copying the missing information on the damaged DNA from the replicated sister chromatid. For this to occur, the two DNA molecules of sister chromatids need to come close together at the exact same genomic position. The team around Daniel Gerlich developed a method that solves this problem.

Computer Program Creates Images Based on Your Brain Waves
News Sep 23, 2020Researchers at the University of Helsinki have developed a technique in which a computer models visual perception by monitoring human brain signals. In a way, it is as if the computer tries to imagine what a human is thinking about. As a result of this imagining, the computer is able to produce entirely new information, such as fictional images that were never before seen.
Interaction Is Important for Girls in STEM
News Sep 23, 2020In a new paper published in the Journal of Research in Science Teaching, researchers took a closer look at a coding camp for middle school girls and found that nuanced interactions between teachers and campers as well as among the girls themselves impacted how girls viewed themselves as coders.
Testing How Kids Pronounce Words Can Predict Their Reading Fluency

AI Technique Copies Human Memory To Minimize Data Storage Burden
News Sep 18, 2020Artificial intelligence (AI) experts at the University of Massachusetts Amherst and the Baylor College of Medicine report that they have successfully addressed what they call a "major, long-standing obstacle to increasing AI capabilities" by drawing inspiration from a human brain memory mechanism known as "replay."
Algorithms Uncover Cancers’ Unseen Genetic Losses and Gains
News Sep 18, 2020Scientists have created new mathematical tools that allow scientists to search the vast collection of DNA snippets and uncover whether there are either missing pieces or duplicates. These algorithms, dubbed HATCHet and CHISEL, could help to improve diagnosis and treatment.
