From love and politics to health and finances, humans can sometimes make decisions that appear irrational, or dictated by an existing bias or belief. But a new study from Columbia University neuroscientists uncovers a surprisingly rational feature of the human brain: a previously held bias can be set aside so that the brain can apply logical, mathematical reasoning to the decision at hand.
Research led by Hui-Yi Lin, Ph.D., Associate Professor of Biostatistics at LSU Health New Orleans School of Public Health, has developed another novel statistical method for evaluating gene-to-gene interactions associated with cancer and other complex diseases.
The organization of our friendships is guided to a large degree by our cognitive capacity when it comes to managing them, that is, by the amount of time and mental effort we can devote to them. This is one of the conclusions of a study which was published by researchers from Universidad Carlos III de Madrid (UC3M) and the University of Oxford and which analyzed these relationships from a mathematical perspective. The study has been published in the latest issue of the PNAS journal.
An international team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has discovered that folding is an efficient strategy to incorporate large-area monolayer graphene films on polymer composites and that doing so improves mechanical reinforcement. Their work has been published in the prestigious journal, Advances Materials.
By applying new data and Princeton's supercomputers to the classic question of what lies beneath our feet, Princeton seismologist Jessica Irving and an international team of colleagues have developed a new model for the Earth's outer core, a liquid iron region deep in the Earth.
Engineers work in quantifiable realism -- an object exists and can be measured. Sometimes, though, the certainty of the object and how it will behave wavers. Researchers from the Automatic Control and System Dynamics Laboratory at the Technische Universität Chemnitz in Germany are starting to close the gap between reality and mathematical uncertainty. They published an analysis of the discrepancy between mathematical proofs, algorithms, and their implementations in control systems with real, measurable outcomes.
University of Kansas education professors have published a study showing that a comprehension-based strategy can help English learners improve their math word-problem solving abilities. The approach boosts reading comprehension and problem solving as well.
The Leibniz Institute for Psychology Information (ZPID) had organized the two conferences from June 7-12 at its seat in Trier, Germany.
A policy of redacting Medicare claims that included diagnosis or procedure codes related to substance abuse was in effect from 2013-2017, just as the Affordable Care Act and the opioid epidemic were drastically changing the healthcare landscape. Researchers from The Dartmouth Institute for Health Policy and Clinical Practice calculated the effects of such a significant data gap on Medicare spending and admissions estimates -- including in one case a $6.8 billion underestimate of inpatient Medicare spending.
In a new research paper, Stanford scholars Rebecca Hetey and Jennifer Eberhardt propose new ways to talk about racial disparities.
