Bias in AI amplifies our own biases, finds study
Credit: Pixabay/CC0 Public Domain Artificial intelligence (AI) systems tend to take on human biases and amplify them, causing people who use that AI to become more biased themselves, finds a…
Targeted or Broadcast? How the Brain Processes Visual Information
Summary: Researchers have uncovered how visual information is processed across the brain’s complex and flexible networks. One study showed visual signals are selectively targeted or broadly broadcast, challenging the idea…
New technology shields wind turbines from positive polarity lightning strikes
Positive charges distributed in the air are concentrated near the conventional air-termination, so positive polarity lightning of the same polarity avoids the positive charges and possibly strike the side of…
Teen Brain’s Blunted Reward Response Predicts Depression Onset
Summary: A new study reveals that a reduced neural response to rewards in teens predicts the first onset of depression, but not anxiety or suicidality. Researchers used EEG scans to…
Ketamine Reduces “Giving Up” by Targeting Brain Support Cells
Summary: Researchers have found that ketamine’s antidepressant effects target astroglia, a type of brain support cell, rather than neurons, challenging conventional views. Using zebrafish, scientists observed that ketamine suppressed the…
AI Tweaks Personality Tests to Appear More Likable
Summary: Large language models (LLMs) can identify when they are being given personality tests and adjust their responses to appear more socially desirable. Researchers found that LLMs, like GPT-4, showed…
Being Watched Changes How Your Brain Processes Faces
Summary: A new study shows that knowing you’re under surveillance triggers a faster, automatic brain response to detect faces and gaze direction. Researchers found that participants monitored via CCTV became…
Hybrid machine learning model predicts financial market volatility with increased accuracy
Daily volatility prediction results from all tested models on the out-of-sample testing set on the S&P 500 Index. Credit: Carnegie Mellon University Mechanical Engineering With volatility so closely tied to…
