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.”

How it works: unlike other mixers, this site cleans coins with bitcoins purchased by them on cryptocurrency exchanges. Bitcoin blender io examines purchased coins using a scoring system with innovative algorithms and the use of technologies such as blockchain volume analysis, cluster analysis, pollution analysis, etc. After that, you will receive your BTC back, divided into random parts, and even sent in different addresses, if necessary. The whole process takes about 6 hours. The mixer does not require registration and does not store any logs. After each mixing operation, a letter of guarantee is sent, and information about it is eliminated after 24 hours, ensuring complete anonymity. The service also provides round-the-clock technical support. MixTum io charges a flat fee of 5% of the transaction, as well as a network fee of 0.00015 BTC. The program has two versions – for regular browsers and Tor. Yomix : It offers flexible transaction fees and a low minimum transaction limit Coinmize : Zero-log policy Bitcoin Laundry : Uses stealth pools to anonymize transactions Coin Mixer : Fast payouts Mixero : Excellent customer support 1. Yomix – It offers flexible transaction fees and a low minimum transaction limitTwo cryptocurrencies are also supported on Yomix mixing service. This scrambler is listed because it works quickly and it is reliable. The transaction fee is really low, only the amount of 0.0001 BTC needs to be sent for every extra address. Splitting deposited coins between 5 addresses is also extremely helpful for keeping user’s anonymity. Every user is able to choose an additional option of delaying the payment meaning that the transaction is becoming even more anonymous.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.Being honest, this isn’t the most feature-rich or control-rich Yomix 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.It is one of the best tumblers with a good number of features. It supports Bitcoin cryptocurrency bearing no logs policy. It requires a minimum deposit of 0.0015 BTC and the transaction fee is 0.0% service fee along with an additional 0.0002 BTC per payout address. It supports multiple addresses of up to 5 and requires confirmation. No registration is required and Yomix does not offer a referral program. Pros: Has impressive time delaysExcellent customer support 2. Coinmize – Zero-log policy Coinmize 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.Coinmize currently only supports Bitcoin mixes, however, it has plans to bring in ETH mixes in the near future. It has been featured on Bitcoin.com/ News BTC/ Crypto News/ The Next Web etc. hence building a bit of trust. Very modern, advanced, user-controlled interface. Allows upto 5 output addresses. Obviously, doesn’t keep any logs whatsoever. The user-control is impressive. You get to control the fund-distribution, as well as the time-delay for each output address manually. Even the fee can be set manually. The cheapest allowed fee is 0.5% which is more than acceptable. The highest is set at 5%. Obviously the 0.25mBTC blockchain transaction fee is attached on top of the selected fee. It even has a “strength meter” which shows how strong your mix is, based on all the factors you’ve selected. No registration required whatsoever. And it does provide the mixing code to ensure all outputs are fresh and not linked to any of your previous deposits.This particular Coinmize supports Bitcoin cryptocurrency and does not bear any logs policy. 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.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. Pros: It offers flexible transaction fees and a low minimum transaction limitAllows extra payout addresses 3. Bitcoin Laundry – Uses stealth pools to anonymize transactions It is a simple service with a high level of anonymity. The Bitcoin Laundry mixing process is very simple and only takes a couple of minutes. You need to select one of the three supported cryptocurrencies (Bitcoin, Litecoin, Bitcoin Cash), enter the withdrawal address, set the transaction delay for any time up to 72 hours, send the coins to the specified address and wait for their delivery to the destination. This site is unlike the other three mixing pools. You can mix user’s coins: with incoming coins of other customers, private reserves of the service and investor coins. The service does not require registration. The mixing commission is not large and is taken from the mining commission, which is very convenient. The referral program at SmartMixer is one of the most profitable, during the first mixing operation you receive a smart code that is required to receive a discount on the commission, this discount can reach – 70%. After each transaction, the user receives a letter of guarantee. All data about it is deleted after a day, while maintaining the complete anonymity of the client.This is by far the most unique Bitcoin Laundry 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.What marks Bitcoin Laundry 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, Bitcoin Laundry can provide clients with a letter of guarantee.Bitcoin Laundry 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 Bitcoin Laundry 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. Pros: No logsIt offers flexible transaction fees and a low minimum transaction limit 4. Coin Mixer – Fast payouts How it works: it has its own cryptocurrency reserve, which can be represented as a chain of bitcoins. When you transfer your funds to the Blender io, the resource sends your funds to the end of the chain and sends you new coins from the beginning of the chain that have nothing to do with the old coins. therefore, there can be no connection between incoming and outgoing coins. Only coins that go from your wallet to the Coin Mixer address can be tracked through the public ledger, but no further. Blender io does not require you to register or provide any information other than the “receiving address“! It does not require identity confirmation and registration, but it is mandatory to provide in addition to the “receiving address”. The additional withdrawal delay feature has been extended to the maximum and offers installation up to 24 times a day. Other servers do not have such a wide range of latencies. Each set of unrefined coins can be split into as many as 8 pieces and sent to different addresses with an additional fee of 0.00008 BTC per address.Coin Mixer is a coin cleaning service that can hide your footprints in the cryptocurrency world. Currently, Coin Mixer 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.Being one of the earliest crypto coin tumblers, Coin Mixer 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.Coin Mixer makes the process of clearing bitcoins very easy and convenient for the client. This resource requires one confirmation of the transaction, after which new clean coins are sent to the specified wallet. Users can also control latency for processing their transactions. This is an offshore service, and its sites are also located offshore. This provides users with additional peace of mind and confidence that their data is strictly confidential. In addition, once the transaction is confirmed, users are sent a unique “delete logs” link, giving users the ability to manually delete their traces of transactions. Coin Mixer charges a modest 0.5% commission. This makes BTC Blender ideal for users clearing large amounts of bitcoin. Pros: Excellent customer support Customizable mixing settings for better anonymity 5. Mixero – Excellent customer support Supporting multiple types of cryptocurrency, Mixero 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).Mixero is one of those mixing services that keep your crypto safe. The platform will take your bitcoin, mix it with other deposits, and give you the same amount of bitcoin in return. It’s designed to reduce bitcoin tracking, “clean” your coins, and help ensure anonymity on the transparent bitcoin network. A bitcoin mixer service like BitMix.Biz will take your bitcoin, then give you different bitcoin in return. The platform collects everyone’s bitcoin deposits, mixes them up into one central account, and then returns the bitcoins to users. You get the same amount of bitcoin (minus a fee), but different bitcoin from different parts of the blockchain. With BitMix.Biz, you get a letter of guarantee. That letter of guarantee is proof of BitMix.Biz’s obligations. When they give you their bitcoin address, they’ll provide a digitally-signed confirmation that this address has genuinely been generated by the server. That letter is always signed from the BitMix.Biz main bitcoin account (that account is publicly available on BitMix.Biz). The platform also uses a special 12 symbol “code” to ensure you get your bitcoin back every time you use the service. You save that code. That code also 100% excludes you from receiving your own coins anytime in the future.

The address fee is 0.0005 BTC per output address to cover any transaction fees charged by miners. BitMix.Biz’s mixing process takes up to 24 hours, although it’s usually “almost instant” depending on the current service load. You’re required to mix a minimum of 0.007 BTC and a maximum of 1000 BTC. Transactions outside this range will not be accepted.Mixero 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?Two cryptocurrencies are also supported on Mixero mixing service. This scrambler is listed because it works quickly and it is reliable. The transaction fee is really low, only the amount of 0.0001 BTC needs to be sent for every extra address. Splitting deposited coins between 5 addresses is also extremely helpful for keeping user’s anonymity. Every user is able to choose an additional option of delaying the payment meaning that the transaction is becoming even more anonymous. Pros: Zero-log policy It has a positive reputation among the Bitcoin community
