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.”

Mixer Money has a deposit requirement of 0.001 BTC and supports a maximum of 2 different addresses. Registration is not compulsory but there is a service charge of 4 – 5% on the amount being transferred. For those with a need for additional privacy, Mixer Money also accepts Bitcoins with a no log policy. Yomix : Fast payouts Bitcoin Laundry : Uses stealth pools to anonymize transactions Bitcoin Mixer : It offers flexible transaction fees and a low minimum transaction limit Coinmize : Zero-log policy Mixero : Excellent customer support 1. Yomix - Fast payouts This is by far the most unique Yomix I’ve ever encountered till date; that’s so pertaining to its “Time-travel” feature! (Whoa!) Basically instead of operating on the traditional receive unclean coins > send clean coins process, it instead uses a create wallet > fund it with chips beforehand > receive unclean coins > grant access to the pre-funded wallet process! This lets users spend the clean coins even before the unclean coins were sent to the mixer (because the wallet was pre-funded) and that’s the reason I termed it the time-travel mixer. Also it funds the wallets with “chips” which are not the same thing as Bitcoins, they’re basically the private keys which can be exported to your Bitcoin wallets to fund your wallets with the amount the chips were worth. It also lets users bet their Chips which has a chance of doubling the worth of their chips, other advanced features include merging which lets users combine two big chips into one single chip, or splitting which divides one big chip into two smaller chips. Its fee structure too is an unique- “Pay what you like” feature, which not only adds to user anonymity by randomizing the fee but also makes the service more affordable and customizable. Because users completely control when or how much funds they wish to withdraw, it translates into 100% user control on time-delays and distribution control. No logs are kept after a 7-day retention period; or there also is an option to manually scrub all logs whenever you wish prior to this 7-day period. The minimum deposit limit on the platform is 0.0001BTC.Yomix is a simple service that will increase your privacy while using and transacting Litecoin. Every single person have its right for a personal privacy even when transacting, trading or donating Litecoin. Due to litecoin blockchain features you are not completely anonymous while using LTC and here comes Litecoin Mixing Service to help you cut all ties between your old and fresh mixed LTC coins. Using LTC mixer makes almost impossible third-parties to trace your new Litecoin Address and find out how wealthy you are.Yomix is being listed at the #1 spot here, well that’s not without substance. The top reasons why I’m in love with this Bitcoin tumbler is because it’s fast, takes care of our anonymity and privacy, and has a very negligible fee. Smartmix bitcoin mixing service The payout is almost instant, all it needs is 2 confirmations for the dirty coins being sent in to be cleaned or tumbled. No account needs to be created to clean your coins either. They have advanced options which let you set “delayed payouts” which further increase your anonymity and make it hard to link the coins going inside to the coins coming out. There’s even an option to add up to 5 addresses, so your coins are broken down into 5 different parts and sent to the different addresses again adding another layer of anonymity. The minimum amount too is pretty low being just 0.001BTC while the maximum limit is 15.32BTC. It’s pocket-friendly as well, with the fee being just 0.5% per mix + 0.0001BTC/address, in fact, it probably is one of the lowest fee in the industry altogether. As for anonymity, they delete all logs related to your mix after 7 days which finally erases the last thread which could ever be linked back to you. So yes, enough reasons to list it at the #1 spot, don’t you agree?Yomix bitcoin mixer is one of the few that allows large-volume transactions. The minimum size for a mixing operation is 0.001 BTC, any amount below this level is considered a donation and is not sent back to the client, there is no maximum transfer limit. The minimum commission is 0.5% with an additional fee of 0.0005 BTC for each incoming transaction. During the transaction, you will receive a letter of guarantee, as in all previously mentioned mixers. Pros: No logsIt has a positive reputation among the Bitcoin community 2. Bitcoin Laundry - Uses stealth pools to anonymize transactions An interesting cryptocurrency tumbler is Bitcoin Laundry. It supports bitcoin and Ethereum cryptocurrencies bearing no logs policy. It requires a minimum deposit of 0.2 BTC and the transaction fee is 2–5%. It does not support multiple addresses and requires 6 confirmations. No registration is required and it does not offer a referral program.What marks Bitcoin Laundry out from the crowd is the fact that this crypto mixer is able to process transactions for Bitcoin and Litecoin.

It requires a minimum deposit of 0.01 BTC and the transaction fee is 1–3%. It supports multiple addresses of up to 10 and requires confirmation. No registration is required and it does offer a referral program.Bitcoin Laundry is a Bitcoin mixing service that provides privacy by using the ‘Bitcoin Mixer 2.0’ algorithm to shuffle bitcoins. Unlike other similar tumbling services that mix your coins with the coins of other users, this platform mixes your crypto with the crypto bought by them directly from the cryptocurrency stock exchanges. Bitcoin Laundry verifies the newly purchased coins with a scoring system with the help of innovative algorithms and outfoxes such technologies as blockchain volume analysis, cluster analysis, taint analysis, etc. It means that you will receive your BTC back split into random parts, and even at the different addresses if needed. Consequently, your privacy is protected as there is no connection to you. And it takes up to 6 hours to complete your request. Another privacy feature of this mixer service is that it does not require registration and it does not store logs. All the transactions are digitally signed with letters of guarantee that you can check on the website at any moment. They also provide 24/7 technical support. MixTum.io will charge you a 5% Fee from your transaction as well as a network fee of 0.00015 BTC. The platform provides two versions – for Clearnet and Tor browsers. Pros: Provides user-controlled time delays Secure Exchange 3. Bitcoin Mixer - It offers flexible transaction fees and a low minimum transaction limitThis Bitcoin Mixer also supports Bitcoin and other cryptocurrencies like Ethereum, Bitcoin Cash, and Litecoin bearing no logs policy.

It supports multiple addresses of up to 10 and requires confirmation from 1 to 50. No registration is required and it does offer a referral program. Also, it comes with a letter of guarantee.Bitcoin Mixer provides all the anonymity and protection that comes standard with a Bitcoin mixer, as well as many optional features and benefits that you won’t find anywhere else. If you use a new address for withdrawal, the coins you receive back are completely separated from your previous history on the blockchain, so it is almost impossible to link the transaction history with your personality. SmartMix commission is only 0.5% of the deposit amount plus 0.0001 BTC / 0.00005 BCH for each exit address. 5 output addresses can be set. The privacy policy makes it possible to delete all mixing information as soon as it is completed. The resource provides fast and reliable mixing of bitcoins through a simple and attractive user interface. Bitcoin Mixer has made two additional functions for its clients in contrast to its colleagues: 1. Affiliate program. Share your anonymous referral link and earn cryptocurrency bonuses. For each mixing operation performed on your link, you receive 50% of the service fee. 2. Loyalty reward program. Use your anonymous SmartClub code with every mixing operation to receive service charge discounts. The more you mix, the more you save.How it works: you fill in the whole amount of the resource account and the Bitcoin Mixer system divides it into small amounts and distributes them to different wallets, mixing them with the coins of other clients or with bitcoins taken on a foreign cryptocurrency exchange, you also get them in small portions to your wallet already washed. This process increases the anonymity of your coins. Features of the service: The main difference between this server is that it has 2 different mixing modes. Cleaning is carried out automatically.In one of the modes, pure BTC is received through foreign cryptocurrency exchanges. Guarantees with PGP signatures are used. Low and high minimum and maximum entry thresholds from 0.001 BTC to 50 BTC. The mixing procedure takes up to 6 hours. Note that there are services that offer to wait 1-2 days. Registration on this platform is not required. Cleaning is carried out automatically. Data encryption is practiced. At the time of writing, Bitcoin Mixer is one of the best BTC mixing services out there. We definitely recommend it.Bitcoin Mixer works by removing the link between your old and current addresses. Since the mixer destroys any connection between them, your traces of transactions and your identity become untraceable. The main advantage is the low commission. Bitcoin Laundry is a donation platform. They charge no service fees, only a transaction fee of 0.0002 BTC to the exit address, while transactions from 0.0005 to 38 BTC are supported. You can set 5 addresses and specify what percentage of the total amount will be returned to each address. You can select predefined or random payment delays for each address, making it even more difficult to track the transaction. Bitcoin Laundry boasts a “no log” retention period policy and also allows users to manually delete logs with just one click if they wish. Pros: Provides user-controlled time delays It has a positive reputation among the Bitcoin community 4. Coinmize - Zero-log policy 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.What marks Coinmize out from the crowd is the fact that this crypto mixer is able to process transactions for Bitcoin and Litecoin. There is a minimum deposit requirement for both Bitcoin and Litecoin. The site is able to support a maximum of 5 multiple addresses with confirmation required for all addresses. No site registration is required and there is a referral program in place. Additionally, Coinmize can provide clients with a letter of guarantee.Coinmize 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. Coinmize does not have a referral program in place.Another trustworthy mixer is Coinmize which supports two cryptocurrencies with Ethereum to be added soon. The mixing process is quite typical and similar to the processes on other tumblers. It is possible to set a time-delay option up to 72 hours and a sender has an opportunity to split the transaction, so the funds are sent to several addresses. Thus, sender’s funds are more secured and untraceable. Pros: Excellent customer support It offers flexible transaction fees and a low minimum transaction limit 5. Mixero - Mixero offers a unique service with a high degree of confidentiality, which will ensure the anonymity of your payments, by using the mixing of multiple Bitcoin addresses. Our system works quickly, reliably and with a small commission – only after the transfer and receipt of funds to the final address. Of course, all of the data about your transaction will be irretrievably deleted.Being one of the earliest crypto coin tumblers, Mixero 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.This platform can work not only as a toggle switch, but also as a swap, that is, you can clear your coins and change the cryptocurrency to another when withdrawing, which further increases anonymity. As a Bitcoin mixer, this platform provides the ability to set a custom commission: the higher the commission, the better the privacy. There is also a time delay option that increases the level of anonymity by delaying the transaction by 24 hours. The service has an impressive supply of coins, so your transactions are made instantly, as soon as confirmation of the receipt of coins arrives, unless you manually set time delays. The minimum deposit is 0.01 BTC per transaction. Any smaller amount is also accepted, but is considered a “donation” and is not returned to Mixero customers. Finally, they also have a no log policy.One of the most currency-rich mixers in the industry, letting us Mix not just Bitcoin but Litecoin, Bitcoin Cash and Ethereum (coming soon) is what Mixero is. Also flaunts probably the most colourful and easy to use Interfaces I’ve ever seen. Provides 100% Control to users regarding every aspect of the mix. As in, users control the exact amount of fee (to the 4th decimal point!), the exact time-delay (by the minute and not just hours) and also the Percentage distribution. It’s transparent and even has a “fee calculator” which displays the exact amount of funds a user would receive on each additional address, as well as the total service and the address-fee. Maximum 8 total output addresses allowed. The minimum service fee a user can pay is 1%, with the maximum being 5%. The additional address fee is 0.00045529 BTC, 0.01072904 LTC, and 0.00273174 BCH for Bitcoin, Litecoin and Bitcoin Cash respectively. Has three fund-pools, and they all have funds from different sources in them which have different levels of anonymity. Does have a “No Logs Policy”. No registration required. Pros: It offers flexible transaction fees and a low minimum transaction limitUser-controlled time delays

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.

Мій досвід на Sea Freedom Fest був далеко не ідеальним. Cosmic Gate, звичайно, виклалися на повну, але на цьому позитив закінчується. Фестиваль був переповнений, зони відпочинку були вщент забиті, а фудкорти не справлялися з потоком людей. Найгірше, що звук на деяких сценах, зокрема «Інь-Янь», був дуже посереднім. Навіть фотозони не рятували ситуацію – все виглядало недопрацьованим і незручним.
