Contact With a Healthy Clone Revives Bleached Corals, Stanford Study Finds
Coral bleaching is usually treated as a slow-motion death sentence. Corals rely on symbiotic algae for much of their energy; when marine heat waves push water temperatures too high, the partnership breaks down, the algae are lost, and the coral turns white. Recovery, when it happens at all, can take months or years.
A study published October 14 in Science Advances suggests that timeline can be dramatically compressed. The idea began with an accident in 2025, when two fragments from the same colony, one healthy and one bleached, fell against each other in the lab of Stanford marine scientist Steve Palumbi. Where they touched, the bleached fragment began to regain color.
Lead author Danny Collins turned the observation into a controlled experiment: ten healthy–bleached pairs, all clones, half in contact and half separated by a few millimeters. All five bleached fragments in contact recovered fully within seven weeks, the fastest documented recovery from bleaching. All five separated fragments died.
The mechanism depends on self-recognition. Genetically identical corals fuse their tissues on contact, and algae then “flood in and start dividing at the fastest rates seen in corals,” Palumbi said. In the second week, algal populations doubled about every four days, roughly ten times the rate observed in wild corals.
The researchers are careful about the limits. Reef-scale use would require pairing every bleached coral with a healthy clone, which is impractical. The team now wants to test whether algae harvested before a heat wave could be delivered in bulk afterward.

Rhode Island Grower Clears 3,000 Pounds, Setting a Record for the Largest Fruit
The 3,000-pound pumpkin has been a long-standing target in competitive giant-pumpkin growing. On October 10, Ron Wallace of Rhode Island reached it, with a pumpkin that weighed 3,156 pounds.
The record Wallace broke was barely a week old. British grower Ian Paton had just set it with a pumpkin of nearly 2,857 pounds. Wallace's entry topped it by roughly 300 pounds, a margin of more than 10 percent.
Botanically, a pumpkin is a fruit: it develops from a flower's ovary and carries seeds. That classification makes Wallace's pumpkin not just the heaviest pumpkin ever weighed but the largest fruit on record.

Alberta's Separation Referendum Fails Decisively, a Boost for Carney's Unity Push
Albertans voted by roughly three to one on Monday to stay in Canada. With more than 1.8 million votes counted and results reported from 84 percent of voting areas, 75 percent opposed beginning a process toward separation, according to unofficial results from Elections Alberta.
The ballot question was deliberately modest. It did not ask about independence itself, only whether to begin a process that could lead to a later vote. Even on that soft question, separatists fell short of the 30 percent that one of their leaders, Jeff Rath of the Alberta Prosperity Project, had said would thrill him.
Alberta's alienation from Ottawa is long-standing. The province holds the world's fourth-largest proven oil reserves, and its political culture has often had more in common with the American West than with central Canada. Some yes voters told reporters they were sending a message of discontent, not voting to leave; Prime Minister Mark Carney suggested only a smaller “hard core” actually wants independence.
The timing mattered. U.S. President Donald Trump's trade war and his talk of annexing Canada as a 51st state have helped Carney rally support in a province where Liberal prime ministers are usually unpopular. Separatists say they turned a fringe cause, once worth 1 or 2 percent of the vote, into a movement that won't disappear.

A Barrel-Shaped Jurassic Squid Relative Upends a Well-Studied Fossil Group
Belemnites, extinct relatives of squid and octopuses, are among the most frequently found fossils in the world, and paleontologists have studied them for more than 200 years. That made a new species described in Papers in Palaeontology all the more surprising.
Wyoteuthis linsterorum lived about 160 million years ago in the shallow inland sea that once covered much of the western United States. Wyoming's Sundance Formation preserves millions of belemnite rostra, the bullet-shaped internal guards that usually make up the whole fossil. Typical specimens there measure 5 to 10 centimeters long and 1 to 2 centimeters wide. The two known Wyoteuthis rostra are about 10 centimeters long and an extraordinary 6 centimeters wide.
CT scanning revealed internal structures linking the species to a belemnite family thought to have vanished millions of years earlier. Co-author Alexey Ippolitov suggests the animal's size, around 60 centimeters with arms, may have let it prey on smaller belemnites, much as modern squid sometimes hunt other cephalopods and even their own kind.
The species is named for Cliff Linster, an amateur collector who found one of the two specimens and died in June, before publication. Both fossils are on display at the Wyoming Dinosaur Center in Thermopolis.

Sixers Crash the Knicks' Banner Night as LeBron James Opens Season 24
Opening night at Madison Square Garden was built as a celebration. The Knicks raised a banner for last season's NBA championship, their first since 1973, before a crowd that included Spike Lee and Ben Stiller. The Philadelphia 76ers then won 106–100.
The subplot was LeBron James. The NBA's career scoring leader, now 41 and beginning a record 24th season, made his debut for his fourth franchise after leaving the Los Angeles Lakers. He and his agent, Rich Paul, had said the Knicks would have been his first choice in free agency had New York not won the title, which helps explain the crowd's chants of “We don't want you!”
James scored a modest 14 points and conceded he “could be a lot better,” noting he had been with the team for just over two weeks. The real damage came from Tyrese Maxey, with 28 points, and Jaylen Brown, a newcomer from Boston, with 19. Asked whether the loss spoiled New York's night, James declined the bait: “It was a great night for New York fans. Fifty-plus years.”

The coral method works in the lab but can't yet be scaled to whole reefs. How should scientists decide which promising ideas are worth the cost of scaling up?
