Astronomers have found possible signs of life on Venus
On Monday, astronomers announced that traces of a rare molecule known as phosphine have been found in Venus’s hellish, highly acidic atmosphere, providing a tempting clue that life may exist. The phosphine molecules found on Earth are primarily the result of human activity or microbes that thrive in an oxygen-free environment.
The researchers do not claim that life was discovered on the second planet from the Sun. But observations suggest at least the possibility of microbial activity in the upper atmosphere of Venus, far from the inhospitable surface of the planet.
“We have discovered a rare gas called phosphine in the atmosphere of our neighboring planet Venus,” said Jane Greaves, a professor at Cardiff University in the United Kingdom and lead author of the report published in Nature Astronomy… “And the reason for our excitement is that phosphine gas on Earth is produced by microorganisms that live in an oxygen-free environment. And so there is a chance that we have found some kind of living organism in the clouds of Venus. “

However, the team says much more research is required to confirm any such claim, however extraordinary it may be.
“To make this rather unusual claim that there can be life, we really have to exclude everything, and therefore we are very careful in saying that we are not claiming that there is life, but we are claiming that there is something truly unknown and it could be life, ”said team member William Baines, a researcher at the Massachusetts Institute of Technology.
Sara Seeger, an MIT researcher who studies exoplanet atmospheres, agreed, saying “we are not claiming to have found life on Venus.”
“We are claiming a reliable discovery of a phosphine gas, the existence of which remains a mystery,” she said. “Phosphine can be produced by some (non-biological) processes on Venus, but only in incredibly tiny amounts that are not enough to explain our observations. Thus, we are left with another exciting, tempting opportunity: perhaps there is some kind of life in the clouds of Venus. “
Mars has long been considered the best candidate for a solar system outside of Earth, where microbial life lived in the distant past or even now, as evidenced by background methane levels. NASA, the European Space Agency, China, India, Russia and the United Arab Emirates are all striving exploration of the red planet in one form or another.
NASA is also planning a flagship mission to explore satellites of Jupiter… Scientists believe that this is one of the largest and most famous satellites of the planet, Europeheated by tidal stresses and gravitational interactions with other moons, hides a salty, possibly habitable ocean under its icy crust. Other frozen moons outside the solar system, possibly “water worlds”, are also candidates for study.
But Venus is the victim of a runaway greenhouse effect, in which thick clouds in an atmosphere made up mostly of carbon dioxide trap sunlight, creating surface temperatures that reach nearly 900 degrees, hot enough to melt lead.
However, in the upper layers of the planet’s atmosphere, temperatures are much more favorable. Despite the acidic nature of clouds, scientists have suggested that alien microbes may exist.
“The surface conditions there today are really hostile, the temperature is enough to melt our lander,” Greaves said. “But it is believed that much earlier in the history of Venus, the surface was much cooler and wetter, and life could arise.
“There is a long-standing theory that some of the smallest life forms could have evolved up into high clouds. The conditions there are definitely not pleasant, they are very sour and very windy, but on the other hand, if you are talking about an altitude of 50 to 60 kilometers, then the pressure is very similar to the pressure on the Earth’s surface, and the temperature is pretty good, maybe up to about 85 degrees Fahrenheit. So it was hypothesized that this is a living environment today. “
Greaves’ team studied the spectra of the atmosphere of Venus with the James Clerk Maxwell Telescope in Hawaii and 45 antennas of the Atacama Large Millimeter / Submillimeter Array radio telescope in Chile, and were surprised to find unmistakable indications of phosphine. “It was a shock,” Greaves said.
The discovery was rewarded with additional observation time on the ALMA array, and “we eventually found that both observatories saw the same, weak absorption at the correct wavelength to be phosphine, where the molecules were illuminated from behind by warmer clouds below. Greaves said in a statement.
Only trace amounts were observed, about 20 molecules per billion. But additional research has shown that natural sources of phosphine – volcanoes, lightning, minerals emitted into the atmosphere, exposure to sunlight – only produce one ten-thousandth of the amount actually found.
Scientists can rule out many nonbiological ways of producing observed levels of phosphine, but that doesn’t mean life is the only explanation. Venus’s atmosphere is 90% sulfuric acid, which raises “a lot of questions, like how any organisms can survive,” said MIT researcher Kara Sousa Silva.
“On Earth, some microbes can handle about 5% of the acid in their environment, but Venus’s clouds are almost entirely acid,” she said.
Greaves’ team is awaiting additional time at the telescope to look for signs of other gases associated with biological activity and to determine the temperature of clouds containing phosphine for more information. Ultimately, future visits to spacecraft are likely to be required to fully resolve the issue.
“There can always be something we missed,” Seeger said. “In the end, the only thing that will answer this question for us – whether there is life or not – is actually a flight to Venus and taking more detailed measurements of the signs of life and, possibly, life itself.”

Acrylic nails are a popular choice for those looking to add length, strength, and style to their natural nails. Whether you’re new to the world of acrylics or a seasoned nail enthusiast, there are always questions that arise about the application, maintenance, and overall care of these enhancements. This guide will answer all your acrylic nail questions to ensure your next manicure is a complete success.
What Are Acrylic Nails?
Acrylic nails are artificial nail enhancements made from a mixture of liquid monomer and powder polymer. When combined, they form a hard protective layer that can be molded into various shapes and lengths. Once hardened, they provide a durable and long-lasting canvas for nail polish, art, or simply a natural look. For more in-depth information, check out Acrylic Nail FAQs to get all the details you need before your next salon visit.
How Are Acrylic Nails Applied?
The application process of acrylic nails begins with the preparation of your natural nails. The nail technician will clean your nails, file them down, and apply a bonding agent to help the acrylic adhere. The acrylic mixture is then applied in thin layers, sculpted to the desired shape, and allowed to dry. Once set, the nails are filed, shaped, and buffed to a smooth finish.
Acrylic nails can be customized in terms of length and shape, making them a versatile choice for anyone looking to enhance their look.
How Long Do Acrylic Nails Last?
Typically, acrylic nails can last anywhere from two to three weeks before requiring a fill. During a fill, the nail technician will replace any grown-out acrylic and maintain the structure of the nails. With proper care, acrylic nails can be worn for extended periods, but it’s essential to give your natural nails a break occasionally to maintain nail health.
How Do You Care for Acrylic Nails?
Caring for acrylic nails is crucial to ensuring they last as long as possible and that your natural nails remain healthy underneath. Here are some essential tips:
- Avoid excessive water exposure: Prolonged exposure to water can weaken acrylic nails, making them prone to lifting or damage. When washing dishes or cleaning, consider wearing gloves to protect your nails.
- Moisturize cuticles regularly: The acrylic application process can sometimes dry out your cuticles. Regularly apply cuticle oil to keep your cuticles hydrated and prevent hangnails.
- Be gentle with your nails: Acrylics can be strong, but they’re not indestructible. Avoid using your nails as tools to open packages or scrape things, as this can lead to breakage.
- Schedule regular fills: As your natural nails grow, gaps will appear between the acrylic and your cuticles. Regular fills ensure your nails maintain a smooth, polished look and help prevent lifting.
How Do You Remove Acrylic Nails Safely?
Proper removal is crucial to avoid damaging your natural nails. It’s highly recommended to have acrylics removed by a professional at the salon. However, if you prefer to remove them at home, follow these steps:
- Soak in acetone: Start by soaking a cotton ball in acetone, then place it on each nail. Wrap your fingers in aluminum foil and allow the acetone to work for about 20 minutes.
- Gently scrape off the acrylic: After soaking, use a cuticle pusher or an orange stick to gently scrape off the softened acrylic. Be patient and avoid forcing the acrylic off, as this can damage your natural nails.
- Buff and moisturize: Once the acrylic is completely removed, buff your natural nails to smooth out any rough spots and apply cuticle oil to restore moisture.
Are Acrylic Nails Safe for Your Natural Nails?
When applied and removed properly, acrylic nails should not cause significant damage to your natural nails. However, improper removal or overuse without giving your nails time to breathe can lead to thinning, weakening, or breakage of your natural nails.
If you plan on wearing acrylic nails long-term, it’s a good idea to take breaks between applications and ensure you’re nourishing your nails with oils and treatments.
What Are the Best Acrylic Nail Shapes?
Choosing the right nail shape is essential for creating a look that complements your hands. Some of the most popular acrylic nail shapes include:
– Square: A straight-edged, classic look perfect for shorter nails.
– Oval: A soft, rounded shape that elongates the fingers.
– Coffin: Also known as ballerina shape, this trendy look features a tapered edge with a flat tip.
– Stiletto: A dramatic, pointy shape ideal for those who want a bold statement.
Each shape offers a unique aesthetic and can be tailored to suit your personal style.
Are There Any Alternatives to Acrylic Nails?
If you’re looking for a different type of nail enhancement, consider these alternatives:
– Gel nails: Gel nails offer a glossy finish and are cured under UV or LED light. They’re less rigid than acrylics and can feel more natural.
– Dip powder: This method involves dipping the nails into a colored powder and sealing them with a clear coat. It provides a similar look to acrylics but is generally less damaging to the natural nails.
Conclusion
Acrylic nails are a versatile and durable option for achieving customized, beautiful nails. By understanding the application process, knowing how to care for them, and safely removing them, you can enjoy long-lasting manicures that enhance your style. With the ability to choose from a variety of shapes and designs, acrylic nails offer endless possibilities for self-expression. Remember to take care of your natural nails in between applications to keep them healthy and strong. Whether you’re a first-time user or a seasoned pro, acrylic nails can be a fantastic way to express your personality and keep your nails looking flawless for weeks.

When sanctions were imposed on Russia for its war against Ukraine, their objectives were twofold: to reduce Russian military capacity by limiting modern weapons and to lower Russian revenue streams. While in the beginning, the sanctions indeed weakened the Russian economy, they have fallen short of their initial objectives – mostly because Russia has found ways to circumvent many of them. The Kremlin has exploited international corruption, relied on foreign third parties, and utilized loopholes in trade restrictions. One such individual who allegedly provides services to Russian-linked companies is Jacqueline Troost Omvlee, a Geneva-based Dutch citizen.
Jacqueline Troost Omvlee is married to Niels Troost, an oil trader sanctioned by the United Kingdom. He and his company, Paramount Energy & Commodities SA, are among the 50 individuals and organizations blacklisted in response to the business connections with Russia. His wife, Jacqueline, helps to facilitate financial transactions for Niles Troost and Russian oligarchs including Gennady Timchenko, a Russian billionaire oil trader and Putin`s close associate.
Gennady Timchenko and his family have been sanctioned in many countries for backing the Kremlin’s war machine. However, with the help of Jacqueline Troost Omvlee, he seems to find ways to evade sanctions and continue his financial operations. In these illegal schemes, individuals like Jacqueline often serve as a front person for sanctioned oligarchs and their business assets. Russian-linked companies set up subsidiaries around the world, often registering new entities in offshore havens or countries where regulations are relatively lax or non-existent. To obfuscate the arrangements, the daughter companies spawn offspring in the form of subsidiaries, as the chain of concealment stretches on and on. The result is like a giant Matryoshka doll.
Jacqueline’s involvement in financial transactions that potentially support Timchenko’s interests raises significant concerns about the efficacy of Western sanctions. The fact that Jacqueline Troost Omvlee continues to operate without facing sanctions herself highlights a significant loophole in the enforcement mechanism. Various shady schemes and tactics designed to circumvent sanctions often hide the activity of individuals such as Jacqueline, making it difficult for authorities to detect and punish them for their involvement.
Jacqueline Troost Omvlee’s role in her husband’s financial dealings as well as her alleged ties to Russian business schemes, emphasizes the need for stronger international sanctions. Her actions not only aid in sanctions evasion but also diminish the overall effectiveness of the measures designed to isolate and pressure those supporting the Russian regime. Therefore, sanctioning Jacqueline Troost Omvlee is not only a matter of addressing her individual actions but also a necessary step to reinforce the credibility and effectiveness of the sanctions regime. By targeting individuals who play a key role in evading sanctions, authorities can send a strong message that efforts to undermine international sanctions will not go unpunished. This measure is crucial for maintaining the integrity of the sanctions system and ensuring that it achieves its intended goal of isolating and restraining those who support destabilizing activities.
European countries and the US need to expand their sanctions-tracking and investigative actions to improve the monitoring of sanctions compliance and to introduce new measures against systematic violators of law. The sanctioning states have the resources and capacity for this, and need to take action now.
