WASHINGTON, July 8 (Reuters) - The planet known as HD 189733b, discovered in 2005, already had a reputation as a rather extreme place, a scorching hot gas giant a bit larger than Jupiter that is a striking cobalt blue color and has molten glass rain that blows sideways in its fierce atmospheric winds. So how can you top that? Add hydrogen sulfide, the chemical compound behind the stench of rotten eggs. Researchers said on Monday new data from the James Webb Space Telescope is giving a fuller picture of HD 189733b, already among the most thoroughly studied exoplanets, as planets beyond our solar system are called. A trace amount of hydrogen sulfide was detected in its atmosphere, a first for any exoplanet. "Yes, the stinky smell would certainly add to its already infamous reputation. This is not a planet we humans want to visit, but a valuable target for furthering our understanding of planetary science," said astrophysicist Guangwei Fu of Johns Hopkins University in Baltimore, lead author of the study published in the journal Nature, opens new tab. It is a type called a "hot Jupiter" - gas giants similar to the largest planet in our solar system, only much hotter owing to their close proximity to their host stars. This planet orbits 170 times closer to its host star than Jupiter does to the sun. It completes one orbit every two days as opposed to the 12 years Jupiter takes for one orbit of the sun. In fact, its orbit is 13 times nearer to its host star than our innermost planet Mercury is to the sun, leaving the temperature on the side of the planet facing the star at about 1,700 degrees Fahrenheit (930 degrees Celsius). "They are quite rare," Fu said of hot Jupiters. "About less than one in 100 star systems have them." This planet is located 64 light-years from Earth, considered in our neighborhood within the Milky Way galaxy, in the constellation Vulpecula. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). "The close distance makes it bright and easy for detailed studies. For example, the hydrogen sulfide detection reported here would be much more challenging to make on other faraway planets," Fu said. The star it orbits is smaller and cooler than the sun, and only about a third as luminous. That star is part of a binary system, meaning it is gravitationally bound to another star. Webb, which became operational in 2022, observes a wider wavelength range than earlier space telescopes, allowing for more thorough examinations of exoplanet atmospheres.

A provocative new study reveals the complex effects of the space environment on human health, providing insight into potential damage to blood, cell structure and the immune system. The study focused on SpaceX's Inspiration4 mission, which successfully sent two men and two women into space in 2021 to orbit the Earth for three days and shed some light on the effects of space travel on the human body. The research data, derived directly from the Inspiration4 mission, shows that even a brief trip to space can significantly damage the human immune system, trigger an inflammatory response, and profoundly affect cell structure. In particular, space travel triggered unprecedented changes in cytokines that play a key role in immune response and muscle regulation but are not usually directly associated with inflammation. In particular, the study found a significant increase in muscle factors, which are physiological responses specific to skeletal muscle cells in microgravity, rather than a simple immune response. Although non-muscular tissues did not show changes in proteins associated with inflammation, specific leg muscles such as soleus and tibialis anterior muscles showed significant signs of metabolic activity, especially increased interleukin in the latter, further enhancing the activation of immune cells.

On the 8th, the Argentine government promulgated the "Foundations and Starting Points for Argentine Freedom" comprehensive bill and a package of fiscal measures, marking the official entry into force of the government reform bill. According to the official gazette of the Argentine government, Argentine President Milley, Chief Cabinet Minister Guillermo Francos and Economy Minister Luis Caputo jointly signed Decrees No. 592 and No. 593 to promulgate these two new reform measures. The comprehensive bill declared Argentina to enter a one-year public emergency in the administrative, economic, financial and energy fields, and granted the president special powers in these fields. It also includes the relaxation of economic regulations, labor reforms and the implementation of a large-scale investment incentive system. The package of fiscal measures involves anti-money laundering, tax deferral, tariffs, re-imposition of high-salary income tax and reduction of personal property taxes. On June 28, after six months of negotiations, the two reform bills were finally passed by the Argentine Congress.

NEW DELHI, July 9 (Reuters) - India's beleaguered Paytm (PAYT.NS), opens new tab has secured approval from a government panel that oversees investments linked to China to invest 500 million rupees ($6 million) in a key subsidiary, three sources with direct knowledge of the matter said. The approval, which still has to be vetted by the finance ministry, will remove the main stumbling block to the unit, Paytm Payment Services, resuming normal business operations. Paytm Payment Services is one of the biggest remaining parts of the fintech firm's business, accounting for a quarter of consolidated revenue in the financial year ended March 2023. A separate unit, Paytm Payments Bank, was wound down this year by order of the central bank due to persistent compliance issues, triggering a meltdown in Paytm's stock. The government panel had earlier held back approval due to concerns about the 9.88% stake in Paytm held by China's Ant Group. India has intensified scrutiny of Chinese businesses since a 2020 border clash between the two countries. All in all, Paytm has been waiting for the nod from the government panel for about two years and without it, it would have had to also wind down its payment services business, which was forbidden from taking on new customers in March 2023. Once the approval has been formalised, it will be able to seek a so-called "payment aggregator" licence from the Reserve Bank of India. The sources, two of whom are government sources, declined to be identified as the decision has not been formally announced. India's foreign, home, finance and industries ministries, whose representatives sit on the panel, did not reply to emails seeking comment. A Paytm spokesperson said the company does not comment on market speculation. "We will continue to make disclosures in compliance with our obligations under the SEBI Regulations, and will inform the exchanges when there is any new material information to share," the spokesperson said.

Kris Jenner is opening up about her health. The reality star shared plans to have her ovaries surgically removed after she was diagnosed with a tumor on one of the organs. “I went to the doctor and I had my scan," she tearfully told daughters Kim Kardashian, Khloe Kardashian and Kendall Jenner on the July 4 episode of The Kardashians. "They found a cyst.” Kris continued, "They said I gotta have my ovaries taken out." While the 68-year-old—who is also mom to kids Kourtney Kardashian, Rob Kardashian and Kylie Jenner—wasn't nervous about the procedure, she did feel very emotional over having to part with her ovaries because, as she put it, "that’s where all my kids were conceived." "It’s also a thing about getting older," Kris noted. "It’s a sign of 'we’re done with this part of your life.' It’s a whole chapter that’s just closed.” She added in a separate confessional, “People often ask me what is the best job you’ve ever had, and I always say mom. The biggest blessing in my life was being able to give birth to six beautiful kids.” And in true Kardashian fashion, Kris' family quickly rallied behind her. After Kourtney called in to check on Kris, the Poosh founder said in a confessional, "I totally understand how my mom is feeling because I would feel the same way." "It’s your womanly power," Kourtney continued. "It doesn’t mean it’s taking away who she is or what she’s experienced, but I would feel this sentimental feeling of what it’s created.” Likewise, Kim empathized with Kris, saying that she feels "really sad for her." "To have a surgery and remove your ovaries is a really big deal," the SKIMS mogul shared. "I couldn’t even imagine being in that situation.” Kris' longtime boyfriend Corey Gamble also showed his support, surprising the momager with a special gift to “help your energy."
