PITTSBURGH The Queen s Gambit, the recent TV mini-series about a chess master, may have stirred increased interest in chess, but a word to the wise: social media talk about game-piece colors could lead to misunderstandings, at least for hate-speech detection software.
That s what a pair of Carnegie Mellon University researchers suspect happened to Antonio Radi?, or agadmator, a Croatian chess player who hosts a popular YouTube channel. Last June, his account was blocked for harmful and dangerous content.
YouTube never provided an explanation and reinstated the channel within 24 hours, said Ashiqur R. KhudaBukhsh a project scientist in CMU s Language Technologies Institute (LTI). It s nevertheless possible that black vs. white talk during Radi? s interview with Grandmaster Hikaru Nakamura triggered software that automatically detects racist language, he suggested.

Irvine, Calif. An interdisciplinary team of biologists and mathematicians at the University of California, Irvine has developed a new tool to help decipher the language cells use to communicate with one another.
In a paper published today in
Nature Communications, the researchers introduce CellChat, a computational platform that enables the decoding of signaling molecules that transmit information and commands between the cells that come together to form biological tissues and even entire organs.

A new study, published in
Bioscience, considers the future of ecology, where technological advancement towards a multidimensional science will continue to fundamentally shift the way we view, explore, and conceptualize the natural world.
The study, co-led by Greg Asner, Director of the Arizona State University Center for Global Discovery and Conservation Science, in collaboration with Auburn University, the Oxford Seascape Ecology Lab, and other partners, demonstrates how the integration of remotely sensed 3D information holds great potential to provide new ecological insights on land and in the oceans.

A new study published in
Nature Communications suggests that the extinction of North America s largest mammals was not driven by overhunting by rapidly expanding human populations following their entrance into the Americas. Instead, the findings, based on a new statistical modelling approach, suggest that populations of large mammals fluctuated in response to climate change, with drastic decreases of temperatures around 13,000 years ago initiating the decline and extinction of these massive creatures. Still, humans may have been involved in more complex and indirect ways than simple models of overhunting suggest.

Ithaca, NY The COVID-19 pandemic has changed life as we know it all around the world. It s changed human behavior, and that has major consequences for data-gathering citizen-science projects such as eBird, run by the Cornell Lab of Ornithology. This worldwide database now contains more than a billion observations and is a mainstay of many scientific studies of bird populations. Newly published research in the journal
