Twitter Bots Are a Major Source of Climate Disinformation

An anonymous reader quotes a report from Scientific American: Twitter accounts run by machines are a major source of climate change disinformation that might drain support from policies to address rising temperatures. In the weeks surrounding former President Trump’s announcement about withdrawing from the Paris Agreement, accounts suspected of being bots accounted for roughly a quarter of all tweets about climate…

Scientists Use Satellite Imagery To Count Elephants

Scientists from a trio of universities have combined satellite imagery with deep learning to detect elephants from space. The goal is to help protect these endangered species from poachers or habitat destruction. Their study was published in the journal Ecology and Conservation. Interesting Engineering reports: The team’s method proved comparable to human detection accuracy and could help solve a number of…

Striped brown dwarf looks a lot like Jupiter

The surface features of brown dwarfs – objects midway in mass between planets and stars – can’t be seen. But researchers have found a way to reveal Jupiter-like stripes and bands in the atmosphere of the closest brown dwarf, Luhman 16B.

Theia 456 is a stretched-out stream of sibling stars

A close look at the “stellar stream” known as Theia 456 finds it contains contains 468 stars born at the same time. Source: https://earthsky.org/space/theia-456-stellar-stream-468-stars-born-together…

Google Trained a Trillion-Parameter AI Language Model

An anonymous reader quotes a report from VentureBeat: Google researchers developed and benchmarked techniques they claim enabled them to train a language model containing more than a trillion parameters. They say their 1.6-trillion-parameter model, which appears to be the largest of its size to date, achieved an up to 4 times speedup over the previously largest Google-developed language model (T5-XXL). As…

InSight and Juno Keep on Trucking

NASA’s InSight lander on Mars and the Juno orbiter at Jupiter have new leases on life. From a report: The spacecraft are expected to continue gathering data about their respective planetary targets during their newly extended missions, allowing scientists to learn more about seismic activity on Mars and turn their attention to the moons of Jupiter. Juno’s mission has been extended…

CERN is Making the Large Hadron Collider’s Data More Accessible

The European Organization for Nuclear Research (CERN) will open up access to more data from Large Hadron Collider (LHC) experiments. Under an updated policy, data will be released around five years after it’s collected and CERN hopes to release the full dataset publicly “by the close of the experiment concerned.” Core LHC collaborators ALICE, ATLAS, CMS and LHCb all endorsed the…

AI Researchers Made a Sarcasm Detection Model

An anonymous reader shares a report: Researchers in China say they’ve created sarcasm detection AI that achieved state-of-the-art performance on a dataset drawn from Twitter. The AI uses multimodal learning that combines text and imagery since both are often needed to understand whether a person is being sarcastic. The researchers argue that sarcasm detection can assist with sentiment analysis and crowdsourced…

Dinosaurs Were Not on the Way Out Before Asteroid Hit, Study Claims

New analysis has refuted the claim that dinosaurs were in decline at the time of their extinction. If an asteroid had not hit Earth 66m years ago, dinosaurs might have continued to dominate the planet, according to new research. From a report: A team from the University of Bath and the UK National History Museum has published a study to Royal…
