Nevertheless, scientific software can have quality quality deficiencies. To evaluate software … [Read more...] about Scientific software – Quality not always good
Data from smartwatches can help predict clinical blood test results: Long-term data gathered from wearables can quicky indicate illness and other abnormalities in a patient’s health
Smartwatches and other wearable devices may be used to sense illness, dehydration and even changes to the red blood cell count, according to biomedical engineers and genomics researchers at Duke University and the Stanford University School of Medicine. The researchers say that, with the help of machine learning, wearable device data on heart rate, body temperature and daily … [Read more...] about Data from smartwatches can help predict clinical blood test results: Long-term data gathered from wearables can quicky indicate illness and other abnormalities in a patient’s health
Quantum sensing: Odd angles make for strong spin-spin coupling: Physicists’ RAMBO reveals magnetic phenomenon useful for quantum simulation and sensing
Sometimes things are a little out of whack, and it turns out to be exactly what you need. That was the case when orthoferrite crystals turned up at a Rice University laboratory slightly misaligned. Those crystals inadvertently became the basis of a discovery that should resonate with researchers studying spintronics-based quantum technology. Rice physicist Junichiro Kono, … [Read more...] about Quantum sensing: Odd angles make for strong spin-spin coupling: Physicists’ RAMBO reveals magnetic phenomenon useful for quantum simulation and sensing
Column: That fraud alert on your phone? It could be part of the scam
Most con artists are just rolling the dice, laying traps they hope unwary consumers will stumble into.This one did his homework in targeting a specific victim — and made off with more than $10,000 from a Chase bank account.The episode serves as a wake-up call for all of us to be very cautious when interacting with businesses, even when everything appears to be on the up and … [Read more...] about Column: That fraud alert on your phone?

Walking in their shoes: Using virtual reality to elicit empathy in healthcare providers
Research has shown empathy gives healthcare workers the ability to provide appropriate supports and make fewer mistakes. This helps increase patient satisfaction and enhance patient outcomes, resulting in better overall care. In an upcoming issue of the Journal of Medical Imaging and Radiation Sciences, published by Elsevier, multidisciplinary clinicians and researchers from … [Read more...] about Walking in their shoes: Using virtual reality to elicit empathy in healthcare providers
These cognitive exercises help young children boost their math skills, study shows
Young children who practice visual working memory and reasoning tasks improve their math skills more than children who focus on spatial rotation exercises, according to a large study by researchers at Karolinska Institutet in Sweden. The findings support the notion that training spatial cognition can enhance academic performance and that when it comes to math, the type of … [Read more...] about These cognitive exercises help young children boost their math skills, study shows
Ultra-sensitive light detector gives self-driving tech a jolt
Realizing the potential of self-driving cars hinges on technology that can quickly sense and react to obstacles and other vehicles in real time. Engineers from The University of Texas at Austin and the University of Virginia created a new first-of-its-kind light detecting device that can more accurately amplify weak signals bouncing off of faraway objects than current … [Read more...] about Ultra-sensitive light detector gives self-driving tech a jolt
