Intravascular ultrasound-guided percutaneous coronary intervention: An updated review

The use of intravascular ultrasound guidance during percutaneous coronary intervention has been shown to improve clinical outcomes, particularly in reducing ischemia-driven target lesion revascularization. IVUS guidance has also been associated with a decrease in intraobserver variability in angiographic borderline lesions.

Scientists take to Twitter to study flying ants, starling murmurations and house spiders

Researchers gathered data on popular ecological phenomena like flying ant emergence and starling murmurations using Twitter hashtags and text, replicating most findings from primary citizen science studies. The study shows that passive citizen science via social media can generate robust and interesting data for ecological research.

Can social media networks reduce political polarization on climate change?

A study by University of Pennsylvania researchers found that exposure to anonymous, bipartisan social networks can lead liberals and conservatives to improve their forecasting of global-climate trends. In the study, 88% of Republicans and 86% of Democrats correctly analyzed climate data after interacting in social media networks.

Dealing with digital distraction

Studies find that even minor phone use during meals can make diners feel distracted, reducing enjoyment. Compassionate people spend less time on social media than those with narcissistic tendencies. Digital distractions undermine face-to-face interactions, causing decreased bonding and emotional intelligence.

Model fuses social media, remote sensing data with goal of identifying nuclear threats

The model uses mathematical equations to translate incompatible data streams into a neutral format, enabling comparison and analysis of satellite imagery and social media posts. Researchers tested the model using data from a 2013 flood in Colorado, resolving incompatibility issues and accurately estimating flooding locations.

Recorded calls beat Facebook ads in getting residents to request free smoke alarm

A Baltimore campaign found that automated phone calls were more effective than Facebook ads in encouraging residents to request free smoke alarm installations. The campaign, which ran in 2014, reached over 90,000 households via landline and resulted in 458 requests for smoke alarms, compared to just 25 from Facebook ads.
