The population of New Zealand's kakapo, an endangered flightless parrot, has increased 25% in the last year to 252 birds following a good breeding season and success with artificial insemination, the conservation department said Tuesday.

The kakapo have been nearly wiped out by introduced predators such as stoats as the birds cannot fly. The problem has been exacerbated by inbreeding, very low fertility - only 50% of eggs are fertilized - and as they only breed every two or three years when native rimu trees fruit.

The population of the kakapo, which is the world’s heaviest parrot, is now at its highest number since the 1970s.

"There were just 86 kakapo when I first started working as a kakapo ranger in 2002. That number was scary. Having a breeding season with 55 chicks feels like a very positive step," said Deidre Vercoe, operational manager for the kakapo recovery program.

The program was established in 1995. It is a collaboration between the New Zealand conservation department and Maori tribe Ngai Tahu and uses volunteers to help with activities like monitoring the nests to keep them out of trouble. Some birds have had to be rescued after getting stuck in the mud or after their legs were caught in trees.

Vercoe said in an email that much of the success this season was due to the amount of fruit on rimu trees.

Success with artificial insemination this season was also key. Eight surviving chicks were born from artificial insemination, compared to just five in the decade to 2019.

"Using artificial insemination has meant that some males, who had not yet naturally fathered chicks, are still represented in the future gene pool," said Vercoe.

"Artificial insemination can also help to increase fertility of the eggs laid."

Most butterflies have short lifespans, fluttering between colorful flowers for a few weeks before dying, but a few rare exceptions have stumped scientists. Now, some long-lived tropical butterfly species are shedding light on the secrets of longevity.

Butterflies belonging to the Heliconius genus, which inhabit the tropical rainforests of South and Central America, have lifespans that vary wildly. The Dione juno butterfly lives for 14 days after reaching adulthood, while Heliconius hewitsoni lives for 348 days — nearly 25 times longer.

Other Heliconius species also have impressively lengthy lives, enduring between 106 to 277 days, according to a study on the phenomenon published Tuesday in the journal Nature Communications.

Some scientists have speculated that Heliconius’ extended adulthood is due to the insects consuming an enhanced diet, rather than relying purely on carbohydrates like other butterflies.

But the exact reasons behind this unexpected longevity have been unclear, which is what inspired Dr. Jessica Foley, the study’s lead author and a postdoctoral scholar at Tufts University’s Jean Mayer USDA Human Nutrition Research Center on Aging in Boston, to take an in-depth look at the intriguing butterfly genus.

“We see vast differences in lifespan across the animal kingdom — adult mayflies famously live only for a day, whereas some whales and sharks can live for hundreds of years,” Foley wrote in an email.

“I’m interested in the evolutionary basis of these kinds of lifespan differences because they might hold insights relevant for healthy ageing in humans,” she added.

Foley and her colleagues discovered that while nutrition has its part to play, some Heliconius have also evolved an anti-aging mechanism the researchers are still unraveling — and how it could be a model for understanding human longevity.

The new research shows that Heliconius can be a potential model insect group for studying increased longevity, including adaptations that could slow aging and have potential applicability to humans, said Dr. Jaret C Daniels, curator and interim associate director for the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of Natural History. Daniels was not involved in the study.

“This study reinforces the utility of many insect groups and important model organisms for various fields of research,” Daniels said in an email.

“Since many insects are often overlooked or underappreciated by humans, studies like this can help change that perspective,” Daniels added.

Plan to Sell Artifacts from Titanic Faces US Government Opposition

A plan to auction more than 100 artifacts salvaged from the wreckage of the Titanic — including personal belongings, currency, kitchen items and decor — is facing pushback from the US government, according to newly unsealed court documents.

RMS Titanic Inc., the company that owns exclusive salvage rights to the famous wreck in the North Atlantic, wants to sell the artifacts for the first time despite previous agreements to only display them at museums and traveling exhibitions.

Georgia-based RMS Titanic proposed auctioning the artifacts and displaying them on a global tour in four cities, although those locations haven't been publicly revealed. Court documents filed in the US referenced the company's plan to sell artifacts including a bronze cherub, a necklace of gold nuggets and a heart-shaped pendant.

The National Oceanic and Atmospheric Administration represents US interests and oversight in the wreck site. The agency contends such a sale would violate RMS Titanic's legal obligations to the site, according to documents a judge ordered unsealed earlier this month.

In arguing that the auction should be prohibited, the government wrote that the company “does not seek the Court’s approval, does not believe that approval is required, and asserts that it is not restricted in its ability to sell” the artifacts.

Representatives for RMS Titanic did not respond to The Associated Press requests for comment Monday. Its attorneys previously said in a federal court filing that the proposed auction arrangement wouldn’t violate existing court orders and agreements about the artifacts.

This is the latest attempt to sell Titanic artifacts Since 1987, salvage operations have retrieved thousands of items and even chunks of the Titanic’s hull. RMS Titanic makes money by exhibiting them.

Over the decades, the company has tried to sell artifacts to fund future explorations and as it faced financial trouble. But those efforts were roundly opposed by US courts along with preservation groups and relatives of the victims. Some of the salvaged items belonged to passengers aboard the ship.

However, items saved by survivors or plucked from the water by rescuers can be sold and often fetch big sums. A life jacket worn by a passenger went for just over $900,000 in April, while a gold pocket watch given to the ship captain who rescued the survivors was sold for nearly $2 million in 2024.

Auctioneers say the unending fascination with the Titanic — which sank in 1912 after hitting an iceberg on its maiden voyage from Europe to New York, killing more than 1,500 people — and the rarity of artifacts adds up to high demand and exorbitant prices.

A trans-Atlantic dispute over the artifacts RMS Titanic wants to auction some of the first artifacts salvaged from the wreck. Those items were taken to France, which awarded ownership of them to the salvager. French oceanographic institute IFREMER partnered with Woods Hole Oceanographic Institution on the discovery of the wreck.

The rest of the collection was retrieved during subsequent expeditions, and the salvage claim was made in a US District Court in Norfolk, Virginia.

NOAA argues that all of the roughly 5,000 items — regardless of whether they were claimed in France or the US — must remain in one collection based on conditions set by the US court. NOAA also maintains on its website that a French court’s conditions required that the artifacts not be sold individually and be kept together as a single collection.

The company has argued, among other things, that the US court lacks jurisdiction over the items claimed in France.

Representatives for the French government did not respond to requests for comment late Monday.

Pieces of history for all to see Some undersea explorers have pushed back at the idea of selling Titanic artifacts, which they argue should be displayed in the public interest.

“I don’t have a problem with people recovering artifacts from the Titanic as long as it’s done careful, with proper archaeological techniques,” said Greg Stone, a veteran ocean explorer and ocean scientist. “I’d feel better if it was a nonprofit enterprise.”

Richard Daynard, a law professor at Northeastern University School of Law in Boston who specializes in public interest advocacy, said rules on the display and sale of Titanic artifacts are intended to preserve the wreckage for the benefit of the public, and so it can't be “picked up by billionaires for further display of their wealth and power.”

“If it’s something where someone can walk through their house and say ‘Yes, I bought this for $5 million and it’s original from the Titanic,’ that’s not a good thing,” he said.
