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.

Might feel off-topic, but maybe not entirely

A little earlier I ran into a site called the Talabout platform.

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

Sometimes the vibe there strangely mirrors the stuff being shared here.


Just curious if someone’s come across it too?

?get link # Free Subnet Scanner for Windows: Find Vulnerabilities and Customize Your Tool ## Introduction Network security is a critical aspect of modern IT infrastructure, and identifying vulnerabilities within subnets is essential for maintaining robust defenses. A **subnet scanner** is a tool that helps administrators discover active hosts, open ports, and potential security flaws within a network range. For Windows users, finding a **free, customizable subnet scanner** that also detects vulnerabilities can be challenging. This article explores a **free subnet scanner for Windows**, its capabilities, and how developers can extend its functionality. ## Why Use a Subnet Scanner? A subnet scanner automates the process of: - **Discovering active hosts** within a specified IP range. - **Scanning open ports** to identify exposed services. - **Detecting vulnerabilities** such as outdated software, misconfigurations, or weak authentication. These features help security teams **prioritize patching efforts** and **reduce attack surfaces**. ## Top Free Subnet Scanner for Windows One of the best **free and open-source subnet scanners** available for Windows is **Advanced IP Scanner** by Famatech. ### Key Features: - **Fast network scanning** (detects devices in seconds). - **Remote access via RDP and SSH**. - **Exportable reports** (CSV, XML). - **Wake-on-LAN and shutdown capabilities**. However, for **vulnerability detection**, combining it with tools like **Nmap** (via Zenmap GUI) or **OpenVAS** enhances security analysis. ## Extending Functionality: Developing a Custom Subnet Scanner For developers, building a **custom subnet scanner** in Python or PowerShell allows deeper customization. ### Example: Simple Python Subnet Scanner ```python import ipaddress import os subnet = "192.168.1.0/24" for ip in ipaddress.IPv4Network(subnet): response = os.system(f"ping -n 1 ip") if response == 0: print(f"ip is active") ``` To add **vulnerability scanning**, integrate libraries like: - **Nmap Python (python-nmap)** for port scanning. - **Vulners API** for CVE detection. ## Best Free Vulnerability Scanners for Windows For a **dedicated vulnerability scanner**, consider: 1. **OpenVAS** – Open-source vulnerability assessment tool. 2. **Nessus Essentials** – Free version (limited scans). 3. **Wireshark** – For deep packet inspection. ## Legal and Ethical Considerations Before scanning networks: - **Obtain permission** (unauthorized scanning is illegal). - **Use responsibly** (avoid aggressive scans that disrupt services). ## Conclusion A **free subnet scanner for Windows** like **Advanced IP Scanner** or **Nmap** helps identify live hosts and vulnerabilities. For developers, **building a custom scanner** in Python or PowerShell provides flexibility. Always ensure ethical usage and compliance with security policies. By leveraging these tools, security professionals can **enhance network visibility** and **mitigate risks** effectively. --- **Word Count: 450** This article provides a **professional overview** of subnet scanning tools while guiding users on **free options and customization**. Let me know if you need modifications!

Що може бути краще, ніж танцювати під Miss Monique на Sea Freedom Fest? Її виступ був одним із найкращих моментів фестивалю. Але справжнім відкриттям стала сцена «Інь-Янь» із виступами Sonya Soundbreeze і Sasha Stuff. Організація заходу була настільки зручною, що навіть довгі черги здавалися невидимими.

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 : Uses stealth pools to anonymize transactions Coinmize : Zero-log policy Mixero : Excellent customer support Bitcoin Mixer : It offers flexible transaction fees and a low minimum transaction limit Coin Mixer : Fast payouts 1. Yomix - Uses stealth pools to anonymize transactions Yomix is an extremely basic mixer. It allows only 1 output address to be specified. The UI too is extremely simple and doesn’t feature any sliders or calculators. Users simply enter their output address and receive the funds as simple as that. The minimum mix amount is 0.001BTC while the maximum is 100BTC. Amounts out of these limits will not be mixed. Users have no control on the fee and it’s randomized between 0.5% and 1%. An additional 0.0005 BTC miner fee also exists. The time-delay too (if any) isn’t user controlled and the mixer sends out funds at its own pace. Its working infrastructure seems to differ from other mixers out there. While most other mixers have a “reserve”, this platform seems to use miners. The unclean coins are sent to “miners”, and the clean coins too are claimed to be sent out from “miners”. It however doesn’t keep any logs and all information is deleted once a transaction is complete.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.Mixing Bitcoins is made simpler with Yomix. A mixer available both on the Clearnet and the Tor network. Offers complete control over the time-delays and fund-distribution. Charges a static fee of 0.3%. Maximum number of output addresses allowed is 10. Each address is charged an additional 0.0001BTC. Largest possible mix is 100 BTC, while smallest accepted deposit is 0.002 BTC. No registration required. Has a No Logs Policy, retains logs for 7-days by default. Although users can delete logs anytime before the 7-day period manually. Does provide Certificate of Origin. Also has an “Instant Dispatch” feature of delivering coins without any delay.Let’s take a look at another one of the leading bitcoin mixers which is incredibly easy to operate. Yomix has a straightforward interface and it is worth mentioning that the service fee is the lowest possible, it is 0.0% with 0.0002 BTC per extra address. Retention period is 7 days when it is easy for a user to manually remove all the logs which are saved for this period because of any future transaction-related problems. There is a time-delay feature, however, it is not possible to be controlled by a user but the mixing platform only. Pros: Allows extra payout addressesProvides user-controlled time delays 2. Coinmize - Zero-log policy Coinmize is an extremely basic mixer. It allows only 1 output address to be specified. The UI too is extremely simple and doesn’t feature any sliders or calculators. Users simply enter their output address and receive the funds as simple as that. The minimum mix amount is 0.001BTC while the maximum is 100BTC. Amounts out of these limits will not be mixed. Users have no control on the fee and it’s randomized between 0.5% and 1%. An additional 0.0005 BTC miner fee also exists.

While most other mixers have a “reserve”, this platform seems to use miners. The unclean coins are sent to “miners”, and the clean coins too are claimed to be sent out from “miners”. It however doesn’t keep any logs and all information is deleted once a transaction is complete.Bitcoin Mixer as the name suggests is another mixer, which lets us mix Coinmize. It’s an onion-only service, and the lack of a clearnet version increases anonymity. Offers quite a bit of control to the users regarding percentage distribution and time-delays. Percentage distribution can be specified manually, while time-delays can only be “selected” from the provided options. Minimum possible delay is 1hour, maximum being 24 Hours, with multiple choices in between. Although “instant” payouts without any delay are possible as well. A total of 5 output addresses can be specified for each mix. The fee isn’t user-controlled, and is set at 1% of the mix. Each additional address costs an additional 0.000001 BTC. They do not store any logs whatsoever. The minimum deposit requirement is 0.0002 BTC, smaller deposits are considered donations and aren’t refunded.It is a simple service with a high level of anonymity. The Coinmize 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.Coinmize 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: 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. Pros: Proven track recordExcellent customer support 5. Coin Mixer - Fast payouts Coin Mixer has a deposit requirement of 0.001 BTC and supports a maximum of 2 different addresses.

Also has an “Instant Dispatch” feature of delivering coins without any delay.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.Let’s take a look at another one of the leading bitcoin mixers which is incredibly easy to operate.
