Calculated surprise leads to groundbreaking discovery in cognitive control research

Humans control their behavior in numerous ways, from stopping the urge pick at a scab to resisting the impulse to eat an entire box of chocolates. Suppressing undesired behavior, referred to as “cognitive control,” traditionally has been linked to the functioning of the dorsal anterior cingulate cortex (dACC) in the front of the brain. Activity in dACC is observed across […]

CRISPR-Cas9 datasets analysis leads to largest genetic screen resource for cancer research

A comprehensive map of genes necessary for cancer survival is one step closer, following the validation of the two largest CRISPR-Cas9 genetic screens in 725 cancer models, across 25 different cancer types. Scientists at the Wellcome Sanger Institute and the Broad Institute of MIT and Harvard compared the consistency of the two datasets, independently verifying the methodology and findings. The […]

Rapid tissue donation program offers feasible approach to improve research

Precision medicine with targeted therapies has led to improved treatment options and patient outcomes. These approaches were developed by studying tumors grown in laboratories and patient samples obtained before and during their treatment. However, there is often a limited supply of patient samples to adequately study, and the samples that exist do not always tell the complete genetic story of […]

New research sheds light on how happy couples argue

In marriage, conflict is inevitable. Even the happiest couples argue. And research shows they tend to argue about the same topics as unhappy couples: children, money, in-laws, intimacy. So, what distinguishes happy couples? According to “What are the Marital Problems of Happy Couples? A Multimethod, Two-Sample Investigation,” a study published this August in Family Process, it is the way happy […]

When does trash talking work? An expert discusses her unusual research

Karen C.P. McDermott recently completed a study on trash talk, the taunts or boasts meant to intimidate or distract an opponent. Her study was one of the first to statistically model how trash talking during a competition can influence performance. What inspired you to study trash talk? Karen C.P. McDermott: In early 2014, I watched Seattle Seahawks cornerback Richard Sherman […]

New research suggests three profiles of communication delays in early childhood

Parenting books, magazines and apps are filled with tools to help parents keep track of their child’s developmental milestones. Parents are often particularly concerned about their child’s language and communication skills. But what does it mean if your child doesn’t meet these early milestones? New research published in the Journal of Developmental and Behavioral Pediatrics suggests that repeated delays in […]

Research moves closer to brain-machine interface autonomy

A University of Houston engineer is reporting in eNeuro that a brain-computer interface, a form of artificial intelligence, can sense when its user is expecting a reward by examining the interactions between single-neuron activities and the information flowing to these neurons, called the local field potential. Professor of biomedical engineering Joe Francis reports his team’s findings allow for the development […]
