Researchers develop innovative approaches to tackle false information on multiple fronts
2024-10-03 01:26:15
As internet usage becomes an integral part of our daily lives, many people rely on various online sources for information. While the internet offers greater convenience and a wider range of news sources, the spread of false information has become one of the biggest challenges of this century, exacerbated by the rise of generative artificial intelligence. The spread of false information—whether in the form of mis-, dis- and mal-information (MDM)—can lead individuals and organizations to make harmful decisions, and has been shown to create societal divisions on critical and contentious issues.
GPS jamming? No problem, low Earth orbit satellites hold the key to resilient, interference-free navigation
2024-10-02 23:35:47
Increasingly occurring GPS jamming in Finland disrupts daily civilian activities, posing major navigational challenges. A new patented method using low Earth orbit (LEO) satellites and massive multiple input multiple output (MIMO) antennas addresses these location vulnerability issues, presenting means for precise navigation even where traditional global navigation satellite systems (GNSS) fail. This breakthrough was verified in a recent doctoral dissertation by Mahmoud Elsanhoury, from the University of Vaasa.
How zapping the brain can supercharge meditation

Desperate for good news about climate change? Consider the pace of clean energy growth
2024-10-02 14:39:36
Climate change has been viewed almost universally as a burden, a hot potato to be passed from country to country at annual climate change conferences. Although it's widely known that climate-friendly solar and wind energy have become cheaper and easier to produce, most don't realize that they are very likely to get even less expensive and grow quickly. That will have enormous political and business consequences, creating not just hazards but also tremendous opportunities.
