Some scientists believe that fatty acids such as decanoic acid and dodecanoic acid formed the membranes of the first simple cell-like structures on Earth, Pearce said.

“(This is) the closest we’ve come to detecting a major biomolecule-related signal — something potentially tied to membrane structure, which is a key feature of life,” Pearce said via email. “Organics on their own are intriguing, but not evidence of life. In contrast, biomolecules like membranes, amino acids, nucleotides, and sugars are central components of biology as we know it, and finding any of them would be groundbreaking (we haven’t yet).”
Returning samples from Mars
The European Space Agency plans to launch its ExoMars Rosalind Franklin rover to the red planet in 2028, and the robotic explorer will carry a complementary instrument to SAM. The rover LS6 will have the capability to drill up to 6.5 feet (2 meters) beneath the Martian surface — and perhaps find larger and better-preserved organic molecules.
While Curiosity’s samples can’t be studied on Earth, the Perseverance rover has actively been collecting samples from Jezero Crater, the site of an ancient lake and river delta, all with the intention of returning them to Earth in the 2030s via a complicated symphony of missions called Mars Sample Return.
Both rovers have detected a variety of organic carbon molecules in different regions on Mars, suggesting that organic carbon is common on the red planet, Williams said.
While Curiosity and Perseverance have proven they can detect organic matter, their instruments can’t definitively determine all the answers about their origins, said Dr. Ashley Murphy, postdoctoral research scientist at the Planetary Science Institute. Murphy, who along with Williams previously studied organics identified by Perseverance, was not involved in the new research.
“To appropriately probe the biosignature question, these samples require high-resolution and high-sensitivity analyses in terrestrial labs, which can be facilitated by the return of these samples to Earth,” Murphy said.

Greenland’s leader says US officials’ visit is ‘highly aggressive.’ Trump says it’s ‘friendliness, not provocation’
[url=https://extrolfi.org]extra finance[/url]
Greenland’s prime minister said a planned visit to the island by US officials, including second lady Usha Vance, is “highly aggressive,” plunging relations to a new low after President Donald Trump vowed to annex the autonomous Danish territory.
But despite the backlash, Trump has insisted the visit is about “friendliness, not provocation” – and claims the US team was “invited.”
Vance, the wife of US Vice President JD Vance, will travel to Greenland this week to watch the island’s national dogsled race and “celebrate Greenlandic culture and unity,” according to a statement from the White House. National security adviser Mike Waltz is also expected to visit the territory this week, according to a source familiar with the trip.
Greenland Prime Minister Mute B. Egede called the US delegation’s trip to the island “highly aggressive” in an interview with Greenlandic newspaper Sermitsiaq on Sunday, and raised particular objection to Waltz’s visit.
“What is the national security adviser doing in Greenland? The only purpose is to demonstrate power over us,” Egede said. “His mere presence in Greenland will no doubt fuel American belief in Trump’s mission — and the pressure will increase.”
Trump claimed on Monday that people in Greenland have responded warmly to the US’s recent interest in the territory. “They’re calling us. We’re not calling them. And we were invited over there,” he said.
“We’re dealing with a lot of people from Greenland that would like to see something happen with respect to them being properly protected and properly taken care of,” Trump told reporters following a meeting with his Cabinet.
“I think Greenland is going to be something that maybe is in our future,” Trump added.
The president said he believes Secretary of State Marco Rubio would be traveling to Greenland too.
Trump’s idea to annex Greenland has thrown an international spotlight on the territory, which holds vast stores of rare earth minerals critical for high-tech industries, and has raised questions about the island’s future security as the US, Russia and China vie for influence in the Arctic. Trump has repeatedly expressed interest in the US taking the island by force or economic coercion, even as Denmark and Greenland have firmly rejected the idea.

‘For the public to enjoy’
[url=https://kepir-app.com]keplr wallet[/url]
The museum’s history starts in 1998, when Sheikh Faisal Bin Qassim Al Thani opened a building to the public on his farm some 20 kilometers (12 miles) north of Qatari capital Doha.
A distant relative of Qatar’s ruling family, founder and chairman of Al Faisal Holdings (one of Qatar’s biggest conglomerates), and a billionaire whose business acumen had him recognized as one of the most influential Arab businessmen in the world, Sheikh Faisal had already amassed a substantial private collection of historically important regional artifacts, plus a few quirky pieces of interest, allowing visitors an intimate look into Qatari life and history.
In an interview with Qatari channel Alrayyan TV in 2018, Sheikh Faisal said that the museum started as a hobby.
“I used to collect items whenever I got the chance,” he said. “As my business grew, so did my collections, and soon I was able to collect more and more items until I decided to put them in the museum for the public to enjoy.”
His private cabinet of curiosities has since evolved into a 130-acre complex. Through the fort-like entrance gate lies an oryx reserve, an impressive riding school and stables, a duck pond and a mosque built with a quirky leaning minaret. There’s now even a five-star Marriott hotel, two cafes and the Zoufa restaurant serving modern Lebanese cuisine.
Of course, there’s also the super-sized museum, with a recently-opened car collection housing everything from vintage Rolls-Royces to wartime Jeeps and colorful Buicks. Outside you’ll find peacocks roaming the grounds, and signs warning drivers to be aware of horses and ostriches.
Visitors to the FBQ museum are free to explore the grounds and can even enter the stables to pat the horses.

Tbilisi, Georgia — Jailed journalist Mzia Amaghlobeli gets weaker every day as her hunger strike has reached three weeks in Rustavi, a town near the Georgian capital of Tbilisi, her lawyer says. Now the 49-year-old is having difficulty walking the short distance from her cell to the room where they usually meet, and human rights officials, colleagues and family fear for her life.

Amaghlobeli was arrested Jan. 12 during an anti-government protest in the coastal city of Batumi, one of over 40 people in custody on criminal charges from a series of demonstrations that have hit the South Caucasus nation of 3.7 million in recent months.

The political turmoil follows a parliamentary election that was won by the ruling Georgian Dream party, although its opponents allege the vote was rigged.
Protests highlight battle over Georgia's future. Here's why it matters.
Its outcome pushed Georgia further into Russia's orbit of influence. Georgia aspired to join the European Union, but the party suspended accession talks with the bloc after the election.
As it sought to cement its grip on power, Georgian Dream has cracked down on freedom of assembly and expression in what the opposition says is similar to President Vladimir Putin's actions in neighboring Russia, its former imperial ruler.

Siham Haleem, a private tour guide for 15 years, says that Doha now has many world-class, modern museums — the National Museum of Qatar being a firm personal favorite. And yet he says that visiting Sheikh Faisal’s museum should still be on everybody’s to-do list.
[url=https://sinpleswap-io.com]simpleswap[/url]
“For those eager to learn about Qatar’s — and the region’s — heritage and beyond, the museum is an ideal destination,” he says. “Personally, I’m captivated by the car collection, the fossils, and especially the Syrian house, painstakingly transported and reassembled piece by piece.”
Stephanie Y. Martinez, a Mexican-American student mobility manager at Texas A&M University in Qatar likes the museum so much she includes it on all of her itineraries for students visiting from the main campus in Texas.
“The guided tours are very detailed, and the collections found at the museum have great variety and so many stories to unfold,” she says. “Truly, the museum has something to pique everyone’s interest. My favorites are the cars and the furniture exhibits showcasing wood and mother-of-pearl details. Definitely one of my favorite museums in Qatar, every time I visit I learn something new.”
Raynor Abreu, from India, also had praise for the unusual and immense collection.
“Each item has its own story, making the visit even more interesting,” he says. “It’s also impressive to know that Sheikh Faisal started collecting these unique pieces when he was very young. Knowing this makes the museum even more special, as it reflects his lifelong passion for history and culture.”
It takes time and dedication to truly examine the many collections within the museum — especially since most of them are simply on display without explanation.
Eclectic it may be, but it’s hard to fault the determination of Sheikh Faisal, who has brought together items that tell the story of Qatar and the Middle East.
Sarah Bayley, from the UK, says she visited the museum recently with her family, including 16 and 19-year-old teenagers, and was won over by its sheer eccentricity.
“Amazing. Loved it. It is a crazy place.”

Remote and rugged
[url=https://eigen1ayer.net]eigenlayer[/url]
A more organic way to see this coast is by the multi-day coastal ferry, the long-running Sarfaq Ittuk, of the Arctic Umiaq Line. It’s less corporate than the modern cruise ships and travelers get to meet Inuit commuters. Greenland is pricey. Lettuce in a local community store might cost $10, but this coastal voyage won’t break the bank.
The hot ticket currently for exploring Greenland’s wilder side is to head to the east coast facing Europe. It’s raw and sees far fewer tourists, with a harshly dramatic coastline of fjords where icebergs drift south. There are no roads and the scattered population of just over 3,500 people inhabit a coastline roughly the distance from New York to Denver.
A growing number of small expedition vessels probe this remote coast for its frosted scenery and wildlife. Increasingly popular is the world’s largest fjord system of Scoresby Sound with its sharp-fanged mountains and hanging valleys choked by glaciers. Sailing north is the prosaically named North East Greenland National Park, fabulous for spotting wildlife on the tundra.
Travelers come to see polar bears which, during the northern hemisphere’s summer, move closer to land as the sea-ice melts. There are also musk oxen, great flocks of migrating geese, Arctic foxes and walrus.
Some of these animals are fair game for the local communities. Perhaps Greenland’s most interesting cultural visit is to a village that will take longer to learn how to pronounce than actually walk around — Ittoqqortoormiit. Five hundred miles north of its neighboring settlement, the 345 locals are frozen in for nine months of the year. Ships sail in to meet them during the brief summer melt between June and August.
Locked in by ice, they’ve retained traditional habits.
“My parents hunt nearly all their food,” said Mette Barselajsen, who owns Ittoqqortoormiit’s only guesthouse. “They prefer the old ways, burying it in the ground to ferment and preserve it. Just one muskox can bring 440 pounds of meat.”

Iceberg flotillas
debridge
Located on the west coast, Ilulissat is a pretty halibut- and prawn-fishing port on a dark rock bay where visitors can sit in pubs sipping craft beers chill-filtered by 100,000-year-old glacial ice.
It’s a place to be awed by the UNESCO World Heritage Icefjord where Manhattan skyscraper-sized icebergs disgorge from Greenland’s icecap to float like ghostly ships in the surrounding Disko Bay.
Small boats take visitors out to sail closely among the bay’s magnificent iceberg flotilla. But not too close.
“I was on my boat once and saw one of these icebergs split in two. The pieces fell backwards into the sea and created a giant wave,” said David Karlsen, skipper of the pleasure-boat, Katak. “…I didn’t hang around.”
Disko Bay’s other giants are whales. From June to September breaching humpback whales join the likes of fin and minke whales feasting on plankton. Whale-watching is excellent all around Greenland’s craggy coastline.
Whales are eaten here. Visitors shouldn’t be surprised to encounter the traditional Greenlandic delicacy of mattak — whale-skin and blubber that when tasted is akin to chewing on rubber. Inuit communities have quotas to not only hunt the likes of narwhals but also polar bears, musk-ox and caribou — which can also appear on menus.
