While the Cumberland sample may contain longer chains of fatty acids, SAM is not designed to detect them. But SAM’s ability to spot these larger molecules suggests it could detect similar chemical signatures of past life on Mars if they’re present, Williams said.

“Curiosity is not a life detection mission,” Freissinet said. “Curiosity is a habitability detection mission to know if all the conditions were right … for life to evolve. Having these results, it’s really at the edge of the capabilities of Curiosity, and it’s even maybe better than what we had expected from this mission.”

Before sending missions to Mars, scientists didn’t think organic molecules would be found on the red planet because of the intensity of radiation Mars has long endured, Glavin said.
Curiosity won’t return to Yellowknife Bay during its mission, but there are still pristine pieces of the Cumberland sample aboard. Next, the team wants to design a new experiment to see what it can detect. If the team can identify similar long-chain molecules, it would mark another step forward that might help researchers determine their origins, Freissinet said.

“That’s the most precious sample we have on board … waiting for us to run the perfect experiment on it,” she said. “It holds secrets, and we need to decipher the secrets.”

Briony Horgan, coinvestigator on the Perseverance rover mission and professor of planetary science at Purdue University in West Lafayette, Indiana, called the detection “a big win for the whole team.” Horgan was not involved the study.
“This detection really confirms our hopes that sediments laid down in ancient watery environments on Mars could preserve a treasure trove of organic molecules that can tell us about everything from prebiotic processes and pathways for the origin of life, to potential biosignatures from ancient organisms,” Horgan said.

Dr. Ben K.D. Pearce, assistant professor in Purdue’s department of Earth, atmospheric, and planetary sciences and leader of the Laboratory for Origins and Astrobiology Research, called the findings “arguably the most exciting organic detection to date on Mars.” Pearce did not participate in the research.

Arctic auroras
ethena
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.

Tesla is bringing its electric cars to oil-rich Saudi Arabia amid falling global sales
aperture finance
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.

Добрый день, друзья! Несколько месяцев назад я побывал в Италии, и там случилась забавная история. Мы с друзьями искали, где можно поужинать недорого, но вкусно. Вспомнил, что на сайте Tripland была рекомендация о небольших семейных ресторанчиках в Риме. Мы нашли одно из таких мест, и оно оказалось настоящим гастрономическим открытием! Хозяева даже подарили нам бутылку домашнего вина в качестве благодарности за визит. Это был вечер, который я запомню навсегда.

This may seem a bit out of place, but it came to mind

A few days back I discovered a site called the Talabout platform.

It’s full of conversations with people from all walks of life — not staged, not your typical media stuff.

Sometimes the vibe there really echoes the stuff being shared here.

Anyone else seen it?

I came from Italy to discover what this festival had to offer, and I wasn’t disappointed. The main stage was buzzing with energy, thanks to outstanding performances by Miss Monique and VovKING. The “Yin-Yang” stage, however, was a revelation. DJs like Sasha Stuff and Antero Mind crafted sets that were both powerful and emotional, creating a magical atmosphere. One of my favorite aspects of the festival was how thoughtfully it was organized. The schedule was clear and easy to follow, and the friendly volunteers made everything even smoother. Whether it was dancing under the lights or relaxing in the chill zones, every moment felt special. This festival has earned a permanent spot on my travel list!

Another coin scrambler Mixtum offers you a so-called free trial period what means that there are no service or transaction fee charged. The process of getting renewed coins is also quite unique, as the tumbler requires a request to be sent over Tor or Clearnet and renewed coins are acquired from stock exchanges. Yomix : Fast payouts Bitcoin Laundry : Uses stealth pools to anonymize transactions Mixero : Excellent customer support Coinmize : Zero-log policy Bitcoin Mixer : It offers flexible transaction fees and a low minimum transaction limit 1. Yomix - Fast payouts In the past, Yomix was one of the most popular Bitcoin mixers available in the cryptocurrency world. The first of its kind, this bitcoin mixer was shut down temporarily before returning to limited service. Nowadays, Yomix is primarily used to facilitate anonymous individual transactions.Yomix is a Bitcoin cleaner, tumbler, shifter, mixer and a lot more. It has a completely different working principal than most other mixers on this list. So, it has two different reserves of coins, one for Bitcoin and the other for Monero. It cleans coins by converting them to the other Cryptocurrency. So, you can either clean your Bitcoins and receive Monero in return, or vice-versa. The interface is pretty straight-forward. You simply choose your input and output coins, and enter your output address. For now, only 1 output address is supported which we believe simplifies things. The fee is fixed which further makes it easier to use. You either pay 0.0002 BTC when converting BTC to XMR, or 0.03442 XMR when converting XMR to BTC. It also provides a secret key which can be used to check transaction status, or get in touch with support. The process doesn’t take long either, Yomix only demands 1 confirmation before processing the mixes. Bitcoin amounts as low as 0003BTC and XMR as low as 0.05 can be mixed. It doesn’t require any registrations so obviously there’s no KYC. The company seems to hate the govt. and has a strict no-log policy as well.Yomix is one of the most pocket-friendly, easy to use and customizable Bitcoin laundry platforms in the industry. The user-interface is extremely simple and clean, anyone who has never before used any such service too can navigate around and tumble Bitcoins easily. No registration is required to mix Bitcoins on Blender.io Its “delay” feature lets you set delays from 1-24 hours which increases your anonymity by providing a gap between the deposited coins and the outgoing ones. As for the fee, it’s dynamic, meaning you get to choose the amount of fee you’d like to pay, the minimum fee being 0.5% and the maximum being 2.5% with an additional 0.0005%/address. It’s also one of the rare platforms which provides you with a mixing code which makes sure your previous coins do not get mixed with your newer deposits if you do multiple deposits to the tumbler. The minimum amount you can mix is 0.001BTC while there’s no specific maximum amount as their Bitcoin reserve seems to be quite large. It also has a No Logs Policy and all data is instantly deleted as soon as a transaction is complete; and as for the number of confirmations required it’s 3 for your deposit to be mixed by Yomix It supports 8 addresses for each mix so you can further increase your anonymity. In a nutshell, it gives you the power to choose, is fast, anonymous and totally worth a try. It also supports Segwit and bech32 Addresses, with some terms attached. For e.g. only witness version bech32 addresses are supported. Similarly, only the addresses starting with the number “3” are supported.Supporting multiple types of cryptocurrency, Yomix is one of the most flexible Bitcoin tumblers available today. Besides requiring a minimum deposit, service fees are charged, and users are required to register to use this site. Referral programs are also on offer along with support for multiple recipient addresses (max 10). Pros: No-logs policiExcellent customer support 2. Bitcoin Laundry - Uses stealth pools to anonymize transactions Being honest, this isn’t the most feature-rich or control-rich Bitcoin Laundry mixer that’s available out there. However, it still averages mixes over 700Bitcoin/day (claimed, not verified). The coins are claimed to be sourced from mining pools in the U.S, China and Europe. Obviously they do not keep any logs. Unfortunately, only 1 output address is allowed which is a bit of a downer. The time-delay can fully be set manually. It can be as low as 0 hours, or as high as 48 hours. Any other delay between this frame can be set using the provided slider. The fee isn’t randomized, neither is it user-controlled. It’s set at a solid 0.1% for all transactions. Accepts a minimum Bitcoin deposit of 0.010BTC. Maximum funds which can be currently mixed stand at 677 BTC. Number of required confirmations depend on the amount. Only 1 is required for mixes below 2.5BTC. For 25 BTC it needs 3 confirmations. 4 confirmations for 40BTC and 5 confirmations for 50 BTC are required respectively. Doesn’t require registrations.Bitcoin Laundry is a coin cleaning service that can hide your footprints in the cryptocurrency world. Currently, Bitcoin Laundry has a minimum withdrawal threshold of 0.03500000 BTC, so users are advised to transfer more than the entry threshold plus commission, otherwise they will not be able to withdraw funds. The client is given 5 exit addresses to be set. If for some reason, even after a delay of two hours, the user’s balance does not update, then the client can contact the support service to take action. For users who have been inactive for several days, it can take up to 15 minutes after logging in before you see outstanding deposits. The logs are kept for 7 days after which they are automatically deleted. The platform runs on a dedicated server that is openly connected via the Internet (you don’t need to do this when using the Tor browser). The Bitcoin mixer runs on a different machine, all suspicious activity is monitored and the website is automatically blocked on any signal that it is under intrusion.Bitcoin Laundry only supports Bitcoin transactions and requires customers to deposit a minimum of 0.001 BTC. Transaction fees range from 0.5 to 3% depending on the amount that is being transferred. This Bitcoin mixer supports multiple addresses and custom options (max of 10). Nonetheless, confirmation is required. Bitcoin Laundry does not have a referral program in place.Being one of the earliest crypto coin tumblers, Bitcoin Laundry continues to be a easy-to-use and functional crypto coin mixer. There is a possibility to have two accounts, with and without registration. The difference is that the one without registration is less controllable by a user.The mixing process can be performed and the transaction fee is charged randomly from 1% to 3% which makes the transaction more anonymous. Also, if a user deposits more than 10 BTC in a week, the mixing service reduces the fee by half. With a time-delay feature the transaction can be delayed up to 24 hours. A Bitcoin holder should worry security leak as there is a 2-factor authentication when a sender becomes a holder of a PGP key with password. However, this mixing platform does not have a Letter of Guarantee which makes it challenging to address this tumbler in case of scams. Pros: Excellent customer support No logs 3. Mixero - Excellent customer support Mixero is yet another simple yet trustworthy Bitcoin Tumbler service. And one of the primary differences it has compared to the other platforms on this list is that it can accommodate really “large volume transactions”. Their claims to have Bitcoin reserves of over 2000BTC has been verified publicly (source: https://bitcointalk.org/generator.php?topic=1484009.msg15350012#msg15350012) so that also makes sure they won’t be running away with our Bitcoins and adds to their credibility. As for the mixing services, the receiving time is instant. Also, they’re pretty trusting and need only the following confirmations:
