Jupiter's clouds have water conditions that would allow Earth-like life to exist, but this isn't possible in Venus' clouds, according to the groundbreaking finding of research led by Queen's University Belfast scientists. For some decades, space exploration missions have looked for evidence of life beyond earth where we know that large bodies of water, such as lakes or oceans, exist or have previously existed.
However, the new research shows that it isn't the quantity of water that matters for making life viable, but the effective concentration of water molecules -- known as 'water activity. The new study also found that research published by an independent team of scientists last year, claiming that the phosphine gas in Venus' atmosphere indicates possible life in the sulphuric acid clouds of Venus, is not plausible. Through this innovative research project, Dr. John E. Hallsworth from the School of Biological Sciences at Queen's and his team of international collaborators devised a method to determine the water activity of atmospheres of a planet.

Using their approach to study the sulphuric acid clouds of Venus, the researchers found that the water activity was more than a hundred times below the lower limit at which life can exist on earth. The research also shows that Jupiter's clouds have a high enough concentration of water, as well as the correct temperature, for life to exist there. The study has been published in Nature Astronomy.

Hallsworth said: "Our research shows that the sulphuric acid clouds in Venus have too little water for active life to exist, based on what we know of life on earth. We have also found that the conditions of water and temperature within Jupiter's clouds could allow microbial-type life to subsist, assuming that other requirements such as nutrients are present.
"This is a timely finding given that NASA and the European Space Agency just announced three missions to Venus in the coming years. One of these will take measurements of Venus's atmosphere that we will be able to compare with our findings."
Co-author of the report, an expert on physics and chemical biology of water, Dr. Philip Ball, commented: "The search for extraterrestrial life has sometimes been a bit simplistic in its attitude to water. As our work shows, it's not enough to say that liquid water equates with habitability. We've got to think too about how earth-like organisms actually use it -- which shows us that we then have to ask how much of the water is actually available for those biological uses."
Co-author of the report, NASA-based planetary scientist Prof. Christopher P. McKay, said: "We derive water activity of atmospheres without a model of any sort, based only on direct observations of pressure, temperature, and water concentration."

Hallsworth added: "We have also performed calculations for Mars and earth and show that these calculations can be done for planets outside our solar system. While our research doesn't claim that alien (microbial-type) life does exist on other planets in our solar system, it shows that if the water activity and other conditions are right, then such life could exist in places where we haven't previously been looking."

Amitabh Bachchan is adored by the public for his unforgettable on-screen performances as well as his magnetic demeanour. Not only do fans love Amitabh Bachchan's outstanding performance, but the actor's heartwarming words are also highly regarded. A much moved Amitabh Bachchan, during his speech to the crowd of over 80,000 people at the Reliance Industries' annual event, said that the legacy left by Dhirubhai has had a positive impact on millions of people's lives worldwide.
When Bollywood superstar Amitabh Bachchan became bankrupt in the late 1990s, Dhirubhai Ambani stepped forward to give him financial assistance. In his speech, Bachchan remembered that Dhirubhai had sent Anil Ambani to offer him financial assistance during the crisis, which he had respectfully declined. Lenders began knocking on his door, losses mounted, and his bank account dwindled to nothing. He said, "Dhirubhai's money might have gotten me out of the problem quickly. However, I respectfully declined his offer and gradually began to find work again, which let me pay off my debt."

Later, after Bachchan had recovered from the bankruptcy, one day he was invited to an event at Dhirubhai's residence; Bachchan added, "Dhirubhai was standing and having a chat with his industrialist friends when he saw me there, he called me, firstly I felt shy even to present myself in front of such big industrialists but then, I went there, and Dhirubhai declared in front of all of them that 'This young man had fallen but managed to get back up on his own, I have a lot of respect for him because of that.' Those words of his were worth much more to me than any amount of money that he could have offered me."
It was the "Reliance Family Day" event and was attended by members of the Ambani family from all generations. The event commemorated the company's 40-year journey since its inception. It also celebrated the 85th birthday of the late Dhirubhai Ambani, RILs (Reliance Industries Limited) founder.

In comparison to adults, children are prone to getting traumatized by troubling events easily, and this makes it important for parents to help their children when the times are tough. It could be a brutal accident, an unprecedented pandemic, a violent crime, or other disasters but with the right parental support, children have a higher chance of coming out stronger from an awful situation.
Anuja Kapur, Psychologist shares few tips wherein you can assist your child when tough times comes calling:
Every child responds differently to disturbing events: What children feel about a current disaster in their life and how they react to it can come and go in waves. Children can act moody and withdrawn at times, struck with sorrow and fear at other times. There's no absolute "right" or "wrong" way to feel after a traumatic event so make sure not to dictate what your child or how your child should feel and react to the event.

Encourage your child to be transparent: Just make sure you let your child know that whatever feelings they're experiencing is normal. The unpleasantness will pass if your child opens up about it and that the phase is temporary. While many teens may be reluctant to talk about their feelings with a parent, encourage them to confide in another trusted adult such as a family friend, relative, or a counselor and teacher. It's important to talkeeven if it's not with you.

Deter your child from reliving the disturbing event: Dwelling over, watching the footage, or imagining the event can be overwhelmingly stressful for children and this stress can even block their nervous system. However, to negate such things from happening encourage activities that keep your child's mind occupied so they're not obsessive about the event. You could encourage your children to read, play games together, or simply watch an uplifting movie.

Cocoon your child with warmth: In order to reassure your child that they are safe with you and feel secure, that the worst is over your physical affection is important in making them feel safe again. Teens may try to be tough through it and avoid being held, but they still need the proximity.

Maintain routines. Establishing a predictable structure and schedule for your child's life can help to make the world seem more stable again. Try to maintain regular times for meals, homework, and family activities. Make sure your child accommodates time and space for rest, play, and fun. Keeping up with a schedule can help countercheck the obnoxious feeling of stress and worry in children about the future being dark, hopeless, and unpredictable.

Acknowledge and validate your child's concerns. The disastrous events in life may give place to unrelated fright and concerns in your child. However, understanding and accepting your child's present state is a comfort for the child. If at any point the child blames himself for the event make sure to make it clear and crisp the event was not their fault, you love them, and it's okay for them to feel upset, angry, or scared but not guilty.

Irrespective of the age of your child, it is vital for parents to offer that extra support and assistance following an unsettling event. The traumatic event may bring up unrelated fears and issues in your child. However, by accepting their thoughts and replacing their fear with your love and direction, the ominous feelings will start to fade away. Eventually, the child will be able to return to a normal and healthy life. (IANS/ MBI)

The European Commission, the executive arm of the European Union (EU), has announced plans for smartphone and other electronics manufacturers to fit a common USB-C charging port on their devices in an effort to reduce waste. In addition to phones, the rules will apply to other devices like tablets, headphones, portable speakers, videogame consoles, and cameras, reports The Verge. The decision will have a huge impact on Apple, as the company still uses its own Lightning connector to charge iPhones. The proposals only cover devices using wired, not wireless and a USB-C port is only mandatory for devices that charge using a cable.

"Chargers power all our most essential electronic devices. With more and more devices, more and more chargers are sold that are not interchangeable or not necessary. We are putting an end to that," the report quoted EU commissioner Thierry Breton as saying.
The Commission also wants to unbundle the sale of chargers from the sale of electronic devices, which it says will improve the consumers' convenience. "With our proposal, European consumers will be able to use a single charger for all their portable electronics - an important step to increase convenience and reduce waste." In addition, the Commission will require manufacturers to provide relevant information about charging performance. (IANS/MBI)
