We’ve all seen that moment in a cop TV show where a detective is reviewing grainy, low-resolution security footage, spots a person of interest on the tape, and nonchalantly asks a CSI technician to “enhance that.” A few keyboard clicks later, and voila—they’ve got a perfect, clear picture of the suspect’s face. This, of course, does not work in the real world, as many film critics and people on the internet like to point out.
However, real-life scientists have recently developed a true “enhance” tool: one that improves the resolution and accuracy of powerful microscopes that are used to reveal insights into biology and medicine.
In a study published in Nature Methods, a multi-institutional team led by
A University of Central Florida researcher is part of a new study showing that artificial intelligence can be nearly as accurate as a physician in diagnosing COVID-19 in the lungs.
The study, recently published in Nature Communications, shows the new technique can also overcome some of the challenges of current testing.
Researchers demonstrated that an AI algorithm could be trained to classify COVID-19 pneumonia in computed tomography (CT) scans with up to 90 percent accuracy, as well as correctly identify positive cases 84 percent of the time and negative cases 93 percent of the time.
CT scans offer a deeper insight into COVID-19 diagnosis and progression as compared to the often-used reverse transcription-polymerase chain reaction, or RT-PCR, tests. These tests have high false negative rates, delays in processing and other challenges.
Another benefit to CT scans is that they can detect COVID-19 in people without symptoms, in those who have
Amsterdam and Helsinki today launched AI registries to detail how each city government uses algorithms to deliver services, some of the first major cities in the world to do so. An AI Register for each city was introduced in beta today as part of the Next Generation Internet Policy Summit, organized in part by the European Commission and the city of Amsterdam. The Amsterdam registry currently features a handful of algorithms, but it will be extended to include all algorithms following the collection of feedback at the virtual conference to lay out a European vision of the future of the internet, according to a city official.
Each algorithm cited in the registry lists datasets used to train a model, a description of how an algorithm is used, how humans utilize the prediction, and how algorithms were assessed for potential bias or risks. The registry also provides citizens a way

GUANGZHOU, China — ByteDance will not transfer algorithms and technologies to Oracle as part of a deal announced over the weekend to keep social media app TikTok operating in the U.S.
President Donald Trump said he approved a deal on Saturday that will see the creation of a U.S.-headquartered firm called TikTok Global with Oracle and Walmart taking minority stakes. Oracle will become TikTok’s secure cloud provider and host U.S. user data.
But the deal does not entail any transfer of algorithms and technologies, according to a statement from ByteDance on Monday. The company said Oracle can instead check the source code.
“The current plan does not involve the transfer of
