A new method for analyzing climate models brings together information from various lines of evidence to represent Earth’s climate sensitivity. Credit: Jason Smith, Oak Ridge National Laboratory, U.S. Dept. of Energy Researchers from institutions including the Department of Energy's Oak Ridge National Laboratory have created a new method for statistically analyzing climate models that projects future conditions with more…

It’s taken more than a decade, but the US Department of Agriculture (USDA) has finally released an updated Plant Hardiness Zone Map that spans the nation and the territory of Puerto Rico in such detail that gardeners can now zoom right into their local areas.This map is used by around 80 million growers to work out what plants have the best chance in the garden, with sellers such as nurseries adopting the zone code to help people find the right fits.The update is well overdue, with many changes across 11 years. Aside from…

Next time you roll your eyes at a weather forecast that got it wrong, just remember that predicting the weather is one of the most complex problems in science. Now, Google has put AI to work as a weatherman, and shown that in just one minute on a single machine, it can make accurate predictions up to 10 days in advance, a task that normally takes a room full of supercomputers hours to achieve.The famous butterfly effect posits that whether or not a storm brews could be influenced by something as small as a butterfly…

By Seth Fiegerman, Bloomberg Google’s DeepMind has developed an artificial intelligence model that uses decades of historical weather conditions to produce accurate 10-day forecasts in less than a minute. GraphCast outperformed the gold-standard forecasting model from the European Centre for Medium-Range Weather Forecasts on roughly 90% of metrics tested, according to a study, which was published in the journal Science on Tuesday. The model also performed well when predicting the most severe weather, the study showed.…

A new AI model Google DeepMind is the world’s most accurate 10-day global weather forecasting system, according to the London-based lab. Named GraphCast, the model promises medium-range weather forecasts of “unprecedented accuracy.” In research published today, GraphCast was found to be more precise and faster than the industry gold standard for weather simulation, the High-Resolution Forecast (HRES). The system also predicted extreme weather from a more distant future than was previously…

Researchers have identified a blood protein that can be used as a marker of gastric and other cancers and is more accurate than existing diagnostic biomarkers, even in the early stages of the disease. The simple test may lead to the earlier diagnosis of often stealthy gastrointestinal cancers.Gastrointestinal cancers, which include esophageal, gastric, colorectal, liver, and pancreatic cancers, often go undetected. The late discovery of these cancers can impact the effectiveness of treatment and contributes to mortality…

If you work in marketing or SEO, looking at data is essential to your day-to-day. You’re probably analyzing performance to see the results of your efforts, assessing the impact of Google’s latest update, or working on a case study to share with the SEO community.But when dealing with SEO data, things are not always what they seem. How you perceive data on a high level may not necessarily be valid once you dig deeper. You need to be thorough, or your assumptions or insights that looked solid initially may be…

The Kens however, reflecting the popularity of the dolls in the real world, play a mainly decorative role. Spoilers for Barbie…

This phenomenon is known as algorithm aversion, and is…
