New research is challenging the scientific status quo on the limits of the nuclear chart in hot stellar environments where temperatures reach billions of degrees Celsius.

The nuclear chart is a way to map out different kinds of atomic nuclei based on their number of protons and neutrons, and the “drip lines” can be viewed as the boundaries or edges of this map. Researchers from the University of Surrey and the University of Zagreb have found that these drip lines, which define the maximum number of protons and neutrons within a nucleus, change dynamically with temperature.

The findings challenge the view that drip lines and the number of bound nuclei are not sensitive to the temperature.

The headline-grabbing release here is Gemma 2, the next generation of Google’s open-weights Gemma models, which will launch with a 27 billion parameter model in June.

Already available is PaliGemma, a pre-trained Gemma variant that Google describes as “the first vision language model in the Gemma family” for image captioning, image labeling and visual Q&A use cases.

So far, the standard Gemma models, which launched earlier this year, were only available in 2-billion-parameter and 7-billion-parameter versions, making this new 27-billion model quite a step up.

Sperm whales rattle off a series of rapid-fire clicks that researchers have named “codas.” Each coda consists of between three and 40 clicks. In addition to changing the number of clicks they make in quick succession, whales often speed up or slow down the tempo of each coda—researchers call this “rubato.” Sometimes, they add an extra “click” at the end of a coda, which scientists call “ornamentation.”

In the end, the team identified 156 distinct codas, each with its own rubato, ornamentation, tempo and rhythm. On their own, these codas may simply be meaningless sounds. But when combined, they could add up to something akin to syllables, words or even sentences.

“We’re now starting to find the first building blocks of whale language,” says study co-author David Gruber, a marine biologist and the founder of Project CETI, to the Associated Press’ Maria Cheng.

With over 100 active wildfires burning in Canada, wildfire smoke has drifted across the border into the United States, prompting Minnesota officials to issue the state’s first air quality alert of 2024.

At least 37 of the 141 active fires burning in Canadian wildfires have been labeled “out of control,” including one that started on Friday in British Columbia and has since spread to 4,200 acres, forcing the evacuation of the small town of Fort Nelson, and the Fort Nelson Indian Reserve, officials said.

Most of the active wildfires, at least 90, are in British Columbia and Alberta provinces.
