Curiosity has maintained pristine pieces of the Cumberland sample in a “doggy bag” so that the team could have the rover revisit it later, even miles away from the site where it was collected. The team developed and tested innovative methods in its lab on Earth before sending messages to the rover to try experiments on the sample.

In a quest to see whether amino acids, the building blocks of proteins, existed in the sample, the team instructed the rover to heat up the sample twice within SAM’s oven. When it measured the mass of the molecules released during heating, there weren’t any amino acids, but they found something entirely unexpected.

An intriguing detection
The team was surprised to detect small amounts of decane, undecane and dodecane, so it had to conduct a reverse experiment on Earth to determine whether these organic compounds were the remnants of the fatty acids undecanoic acid, dodecanoic acid and tridecanoic acid, respectively.

The scientists mixed undecanoic acid into a clay similar to what exists on Mars and heated it up in a way that mimicked conditions within SAM’s oven. The undecanoic acid released decane, just like what Curiosity detected.

Each fatty acid remnant detected by Curiosity was made with a long chain of 11 to 13 carbon atoms. Previous molecules detected on Mars were smaller, meaning their atomic weight was less than the molecules found in the new study, and simpler.
“It’s notable that non-biological processes typically make shorter fatty acids, with less than 12 carbons,” said study coauthor Dr. Amy Williams, associate professor of geology at the University of Florida and assistant director of the Astraeus Space Institute, in an email. “Larger and more complex molecules are likely what are required for an origin of life, if it ever occurred on Mars.”

Tesla is bringing its electric cars to oil-rich Saudi Arabia amid falling global sales
[url=https://arperturlefinamce.fi]aperture finance[/url]
Tesla will start selling its electric vehicles in Saudi Arabia, entering the Gulf region’s largest economy as the company’s global sales are sliding and CEO Elon Musk courts controversy with his role in the US government.

The carmaker announced Wednesday that it would host a launch event in the kingdom on April 10, where it will showcase its EVs. Attendees will also have the chance to “experience the future of autonomous driving with Cybercab and meet Optimus, our humanoid robot, as we showcase what’s next in AI and robotics,” Tesla (TSLA) said.

Tesla may struggle to gain market share in oil-rich Saudi Arabia as EVs make up a little over 1% of all car sales in the country, according to a report by consultancy PwC published in September.
Tesla’s entry into the new market comes as the company fights battles on several fronts.

Last year, it recorded the first annual decline in sales in its history as a public company, posting a drop of 1%.

The company is facing intensifying competition in China, the world’s largest auto market. On Tuesday, BYD, a Chinese maker of electric and hybrid cars, reported $107 billion in annual sales for 2024, beating the near-$98 billion notched by Tesla.

And last week, BYD unveiled an ultra-fast charging system, which it said was capable of adding 250 miles (402 km) of range in just five minutes, easily outdoing Tesla’s charging technology. Tesla’s Superchargers take 15 minutes to charge an EV, providing a range of 200 miles.

Tesla has also suffered slumping sales in Europe. In February, the carmaker sold around 40% fewer vehicles on the continent compared with the same month in 2024, according to the European Automobile Manufacturers’ Association.

Arctic auroras

For getting around during winter, the Inuit here nowadays prefer snowmobiles, although they still keep their sled dogs. During winter they’ll offer intrepid visitors, wrapped up warm against the deep-freeze temperatures, dog-sledding jaunts. These can last either an hour or be part of expeditions over several days, sometimes with the added experience of learning how to build an igloo. Sisimiut on the west coast and Tasilaq in the southeast are active winter centers for dog sledding.

Winter’s most stellar attraction, though, is northern lights watching. With little urban light pollution, Greenland is a dark canvas for spectacular displays, and aurora borealis-watching vacations are becoming more popular.

Staying outdoors, Greenland is developing a reputation among adventure enthusiasts: from long-distance skiing expeditions and heliskiing on the icecap to hiking the 100-mile-long Arctic Circle Trail from Kangerslussuaq, where firearms need to be carried for warning shots in case of polar bear encounters.

Life is definitely changing here. The climate crisis is eating away at its icecap and Greenland may well end up as a pawn in a game of geopolitical chess. But for now, the bright glare of international attention should shine a favorable light on one of the wildest travel destinations on Earth.

Travel writer Mark Stratton is an Arctic specialist who has traveled to Greenland six times and counting. He’s marveled at the aurora borealis, sailed to Disko Island, dog-sledded with the Inuit, and once got stuck in an icefloe.

WASHINGTON — “Liberation Day” just gave way to Capitulation Day.

President Donald Trump pulled back Wednesday on a series of harsh tariffs targeting friends and foes alike in an audacious bid to remake the global economic order.

Trump's early afternoon announcement followed a harrowing week in which Republican lawmakers and confidants privately warned him that the tariffs could wreck the economy. His own aides had quietly raised alarms about the financial markets before he suspended a tariff regime that he had unveiled with a flourish just one week earlier in a Rose Garden ceremony.

The stock market rose immediately after the about-face, ending days of losses that have forced older Americans who've been sinking their savings into 401(k)s to rethink their retirement plans.

Ahead of Trump's announcement, some of his advisers had been in a near panic about the bond markets, according to a senior administration official. Interest rates on 10-year Treasury bonds had been rising, contrary to what normally happens when stock prices fall and investors seek safety in treasuries. The unusual dynamic meant that at the same time the tariffs could push up prices, people would be paying more to buy homes or pay off credit card debt because of higher interest rates. Businesses looking to expand would pay more for new loans.

Two of Trump's most senior advisers, Treasury Secretary Scott Bessent and Commerce Secretary Howard Lutnick, presented a united front Wednesday, urging him to suspend the tariffs in light of the bond market, the administration official said.

In a social media post, Trump announced a 90-day pause that he said he’ll use to negotiate deals with dozens of countries that have expressed openness to revising trade terms that he contends exploit American businesses and workers. One exception is China. Trump upped the tariff on the country’s biggest geopolitical rival to 125%, part of a tit-for-tat escalation in an evolving trade war.

Trump reversed course one week after he appeared in the Rose Garden and unveiled his plan to bring jobs back to the United States. Displaying a chart showing the new, elevated tariffs that countries would face, Trump proclaimed, “My fellow Americans, this is Liberation Day.”
