Michigan DNR working to bring back fish ‘lost' since 1930s
The DNR is continuing its work to reintroduce the back to Michigan waters. The agency is working alongside several local tribes, including the Little River Band of Ottawa Indians, the Little Traverse Bay Bands of Odawa Indians and the Grand Traverse Band of Ottawa and Chippewa Indians.

Eggs are being hatched at the Oden State Fish Hatchery near Petoskey. Approximately 400,000 eggs will be released along three different rivers in northern Michigan .
The Michigan Arctic grayling was considered extirpated in the 1930s. Once plentiful in the state's rivers and streams, the Arctic grayling descended from a fish that lived in Michigan waters since the glaciers of the Ice Age receded.
According to Dan Kimmel with , several factors played a role in the grayling's doom, including the state's timber industry.

'The logjams scoured the streams and all but destroyed grayling spawning areas,' . 'Cutting the trees down also caused serious silting problems that literally choked the streams in which the grayling lived.
'Those streams, lacking the canopy shade the bankside trees provided, soon became unsuitably warm for the grayling. The delicate balance of nature tipped and the little grayling, unable to adapt to the large-scale changes facing it, began to disappear.'
Overfishing and the introduction of non-native trout, including rainbow trout and the European brown trout, nearly forced the Michigan population of Arctic grayling to disappear.

'The last specimens were taken in the 1930s as part of a last-ditch effort to rescue the fish and keep it swimming our state's waters,' Kimmel wrote.
Attempts have been made in the past to bring grayling back to Michigan waters, pulling populations from other areas, including Alaska and western Canada. The DNR started its latest initiative with the local tribes in 2016.

London team helps Jersey with archaeological finds
Archaeologists from London are visiting Jersey to help catalogue and store hundreds of ice age animal bone from an ancient site. Jersey Heritage said while the items, found before 1960 at La Cotte de St Brelade, had been subjected to detailed work, the early finds were yet to be studied using modern scientific techniques. It said visitors could meet the team from the University College London (UCL) Institute of Archaeology for a free "Meet the Collections" event on Saturday at Sir Francis Cook Gallery. The finds, which are part of a Société Jersiaise collection, include a fragment of woolly mammoth bone and lots of pieces of horse, red deer, bison, and bear bones, said Jersey Heritage. It added the UCL team was interested in the remains of animals that may have been hunted by some of the last surviving Neanderthal groups in the region. Jersey Heritage said: "There is no reason why some of these fragments of bone might not be from the Neanderthal people themselves." More news stories for Jersey Listen to the latest news for Jersey Curator of archaeology at Jersey Heritage, Olga Finch, said: "It's great to have the expertise of the London team to undertake this curatorial work and provide a detailed catalogue, which the public and researchers can access to learn more about this important story in the Island's history." Dr Matt Pope from UCL said it was exciting to be involved in the "important process". "This is one of the most important collections of Ice Age animal bone in the region and we are getting every ready to unlock its secrets," he added. Follow BBC Jersey on X and Facebook.

China releases AI action plan days after the U.S. as global tech race heats up
SHANGHAI — The tech race between the world's two largest economies just intensified. China on Saturday released a global action plan for artificial intelligence, calling for international cooperation on tech development and regulation. The news came as the annual state-organized World Artificial Intelligence Conference kicked off in Shanghai with an opening speech by Premier Li Qiang, who announced that the Chinese government has proposed the establishment of a global AI cooperation organization, according to an official readout. Days earlier, U.S. President Donald Trump announced an American action plan for AI that included calls to reduce alleged "woke" bias in AI models and support the deployment of U.S. tech overseas. "The two camps are now being formed," said George Chen, partner at the Asia Group and co-chair of the digital practice. "China clearly wants to stick to the multilateral approach while the U.S. wants to build its own camp, very much targeting the rise of China in the field of AI," Chen said. He noted how China may attract participants from its Belt and Road Initiative, while the U.S. will likely have the support of its allies, such as Japan and Australia. In his speech, Premier Li emphasized China's "AI plus" plan for integrating the tech across industries and said the country was willing to help other nations with the technology, especially in the Global South. The category loosely refers to less developed economies, especially countries outside the U.S. and European orbits. Since 2022, the U.S. has sought to restrict China's access to advanced semiconductors for training AI models. Earlier this month, U.S. chipmaker Nvidia said the U.S. was allowing it to resume shipments of a less advanced H20 chip to China after a roughly three-month pause. However, China has been developing homegrown alternatives, which Nvidia CEO Jensen Huang both praised and described as "formidable" during his third trip to China this month. Former Google CEO Eric Schmidt met with Shanghai Party Secretary Chen Jining on Thursday in the city ahead of the AI conference, according to a city announcement. Schmidt did not immediately respond to a CNBC request for comment.

Greenland Sharks Can Live to Be 392. Why Can't I?
As a general rule I do not get jealous of other creatures that inhabit this planet. This is largely because most creatures have a hard time feeding themselves, are constantly in fear of predators and live relatively short lives. But when I found out that the Greenland Shark has been known to live to be 392 years old, for the first time in my life I felt pangs of envy.
