Scientists Reveal That Liquid Water Once Flowed Through the Parent Body of Asteroid Ryugu

This water flow took place on ancient asteroids over a billion years after their formation, likely due to the heat generated by melting ice, which caused rock fractures that facilitated water movement. JAXA’s Hayabusa-2 Spacecraft.

This image of the asteroid was taken on June 26, 2018, by JAXA’s Hayabusa-2 Spacecraft optical navigation camera – telescopic (ONC-T).

Ryugu is a CG-type asteroid close to Earth and part of the Polana family of impact asteroids.

The diamond-shaped body, also known as 1999 JU3, was identified by astronomers in May 1999 during asteroid studies near Lincoln.

Its diameter measures about 900 m (0.56 miles), and it orbits the Sun at a distance of 0.96-1.41 Astronomical Units (AU) every 474 days.

“We have a relatively good understanding of how the solar system was formed, though many gaps remain,” said Shiyoshijima, a researcher at the University of Tokyo.

“One gap in our knowledge is how Earth acquired its water.”

“It has long been known that carbonaceous asteroids, originating from ice and dust in the outer solar system, have contributed water to Earth.”

“We discovered that Ryugu preserves an unaltered record of water activity, indicating that liquid water moved through the rock much later than previously anticipated,” added Dr. Ikemoto.

“This shifts our understanding of the long-term fate of water on asteroids. The water has remained for an extended period and hasn’t been depleted as quickly as we thought.”

In this study, the authors examined the isotopes of lutetium (Lu) and hafnium (HF), with the radioactive decay from lutetium-176 to hafnium-176 serving as a sort of clock to gauge geological processes.

The expected presence of these isotopes in the studied sample was hypothesized to correlate with the asteroid’s age in a predictable manner.

However, the ratio of Hafnium-176 to Lutetium-176 was significantly unexpected.

This strongly suggests to researchers that the liquid effectively washed away lutetium from the rocks containing it.

“We anticipated that Ryugu’s chemical signatures would align with certain meteorites currently under examination on Earth,” Dr. Iizuka stated.

“However, the results were strikingly different, necessitating the careful elimination of other possible explanations, ultimately concluding that the Lu-HF system was hindered by a delayed liquid flow.”

“The most probable triggers involved the parent body of Ryugu’s larger asteroid, which disrupted the rocks, melting the embedded ice and allowing liquid water to permeate the body.”

“It was truly surprising! This impact event could be the catalyst for the parent body disruption.”

One of the crucial implications is that carbon-rich asteroids may be a significant source of water for Earth, supplying far more than previously estimated.

Ryugu’s parent body seems to have retained ice for over a billion years. This suggests that similar bodies impacting the young Earth could have delivered 2-3 times more water than standard models predict, significantly influencing the planet’s early oceans and atmosphere.

“The notion that a Ryugu-like object has preserved ice for such an extended time is remarkable,” Dr. Ikemoto remarked.

“It implies that Earth’s components were far wetter than we had imagined.”

“This prompts a reevaluation of the initial conditions for the planetary water system.”

“It’s still early to draw definitive conclusions, but my team and others may build on this research to clarify various aspects, including how our planet became habitable.”

The findings will be published in the journal Nature.

TikTok’s Parent Company Plans $300 Billion Stock Buyback

ByteDance, the parent company of the short video platform TikTok, is set to initiate a new employee stock buyback, valuing the Chinese tech powerhouse at over $330 billion, as its revenue continues to climb.

The firm plans to offer its employees $200.41 per share through a repurchase program. This valuation marks a 5.5% increase from $189.90, which was offered approximately six months ago.

The buyback initiative is expected to roll out in the fall.

The new buyback program, reflecting higher valuations, comes as ByteDance strengthens its position as the leading social media entity globally in terms of revenue, with second-quarter earnings rising 25% year-over-year, according to sources.

The surge indicated that the company’s second-quarter revenues reached nearly $48 billion, with a significant portion derived from the Chinese market despite ongoing political pressures regarding its US operations.

Details concerning the updated valuation and second quarter revenue growth had not been previously disclosed. The source requested anonymity as they were not authorized to speak to the media.

ByteDance did not immediately respond to the request for comment.

In the first quarter, ByteDance’s revenues exceeded $43 billion, establishing it as the number one social media company globally in terms of revenue, surpassing Meta’s $42.3 billion during the same period.

Both companies maintained sales growth of over 20% in the second quarter, driven by robust advertising demand.

ByteDance’s semi-annual buyback program allows employees of the private company to liquidate some of their holdings, showcasing a balance sheet strengthened by expanding both domestic and international operations.

It is becoming increasingly frequent for late-stage private firms to engage in regular buybacks to provide liquidity to employees without needing to go public prematurely.

Many organizations, including SpaceX and OpenAI, utilize external investors to fund these initiatives. However, ByteDance stands out as it consistently leverages its own balance sheet, reflecting financial flexibility and solid margins. The firm is also recognized as one of China’s AI leaders, investing billions in Nvidia chips, establishing AI infrastructure, and developing new models.

TikTok Sale

Despite surpassing Meta’s revenue this year, ByteDance’s valuation is less than one-fifth of Meta’s market capitalization, a discrepancy analysts largely attribute to political and regulatory risks faced in the US.

ByteDance is currently under significant scrutiny in Washington, where lawmakers are voicing national security concerns regarding its Chinese ownership.

Last year, Congress enacted legislation mandating that TikTok’s US assets be divested by January 19, 2025, or risk facing a nationwide ban affecting its 170 million US users. Donald Trump has made multiple remarks regarding TikTok and postponed the asset sale deadline until September 17, claiming that US buyers are lined up and that another extension could be possible.

Some lawmakers have criticized the delay, alleging that the administration is neglecting the law and disregarding national security worries related to China’s control over TikTok. While ByteDance is profitable, TikTok’s US operations have reportedly incurred losses, according to two sources. TikTok has not responded to Reuters’ request for comment.

If TikTok’s US assets are divested, they are expected to be owned by a joint venture involving an American consortium of investors and ByteDance.

The consortium currently leading the charge includes ByteDance’s existing shareholders, Susquehanna International Group, Atlantic General, KKR, and Andreessen Horowitz. Blackstone recently withdrew from the consortium, citing delays in the transaction timeline. A new ByteDance buyback could bolster morale among US-based employees, many of whom are concerned about TikTok’s uncertain future. The company is also reportedly working on a potential standalone app for US users, but it’s unclear if this contingency plan will be finalized amidst ongoing trade discussions between Trump and Beijing.

Parent educates on internet safety after child’s Roblox issue: Man approached him

dAvid, 46-year-old father from Calgary, Canada. My 10 year old son didn’t see any problems at first I started playing on Roblox, a user-generated gaming and virtual environment platform, especially among younger gamers, which has exploded in popularity in recent years.

“We thought he was a way to maintain a level of social interaction during the blockade of the community,” David said he assumed that his son would use the platform’s chat feature to speak to friends he personally knows.

After a while, his parents found him talking to someone in his room in the middle of the night.

“We discovered that a man from India approached him and approached him with Roblox and mentored him to bypass our internet security management,” David said. “This person persuaded his son to take nude pictures and videos that he compromised and send them via Google Mini.

“It was tough to get to the root of why my son did it. I think he was lonely. I thought this was a real friend. I think he was given a gift to Roblox, who made him feel special. It was truly the worst nightmare for all parents.”

David was among parents all over the world who often shared with the Guardian that primary school children were either heavily affected or had serious harm from the games at Roblox. Many confirmed the results of reports last year that Roblox allegedly exposed children to grooming, pornography, violent content and abusive speech.

Some parents said Roblox was a creative outlet for their children and brought joy to them or improved some of their skills, such as communication and spelling, but the majority of parents who were in touch with expressed serious concern. These were primarily about the incredible levels of addiction we observed with our children, but also about extreme political images such as parental control, grooming, emotionally horrifying mail, bullying, and avatars of Nazi uniforms, as well as examples of traumatic content in games that children can access despite inappropriate talking to children on the platform.

“Deeply disturbing” research By digital behavior experts who reveal reality The 5-year-old was able to communicate with adults while playing games on the platform.

Roblox admitted in response to the possibility that children playing on the platform could be exposed to harmful content and “bad actors.” This is an issue that the company claims to be working hard to fix it, but requires industry-wide collaboration and government intervention. The company said “I have deep sympathy.”

The newly announced, additional safety tools aimed at giving parents greater flexibility to manage their children’s activities on the site, have failed to convince many of the parents the Guardian spoke to.

“I don’t think the change will address my concerns,” said Emily, Hemel Hempstead’s mother.

“The new features are useful, but they don’t stop children from accessing inappropriate or scary content. People are allowed to choose an age rating for the game they create, and they may not always be appropriate or accurate.

Her 7-year-old daughter said that her 7-year-old daughter was asleep as she was shot after Roblox’s game took her to a room with an avatar where she was introduced as “your dad.”

Despite Roblox claiming to have introduced “new easy-to-use “remote management” parental controls,” parents found it extremely difficult to navigate parental control settings and said it takes several hours to review their child’s activities regularly. It was also impossible to tell people that many people were behind their usernames.

“Roblox monitors the type of language used, such as blasphemy, but there is no real way to policing players’ age.

The company highlighted last year that it defaulted to the fact that under 13 years of age could no longer send messages directly to others on Roblox, outside of gaming or experience.

However, Roblox admitted that it struggles to verify users’ age, saying, “age verification for users under 13 is still a challenge for the wider industry.”

Nelly*, a Dublin mother in her 40s, said she had just finished a play therapy course to process sexual content her 9-year-old daughter saw on Roblox, which caused a panic attack.

“I thought it was okay to play,” she said. “I didn’t allow her to be friends with strangers either, and I thought this would be enough, but it wasn’t.

“There was an area where she went, people were wearing underwear and someone went in and lying on her.”

Many parents felt that Roblox was exploiting his child’s “underdeveloped impulse control.” As one father said, he constantly gave them a nidge to gamble and stay on the platform, urging many children to lose interest in other activities in the real world.

Jenna, from Birmingham. Two months after her children began playing Roblox, they were able to see their “all life” [had] It is carried over by the platform and reflects the statements of other parents’ scores.

“I feel like I’m living with two addicts,” she said. “If they’re not playing, they want to watch a video about it… When they’re told to go off, it’s like you cut them off from their final fix – screaming, arguments, sometimes pure rage.”

Peter, 51, a London artist and father of three boys, said that his 14-year-old son became so engrossed in Robras and his devices that he was generally violent, breaking the windows with his fist when the game was turned off.

“People who run Roblox don’t give parents shit that they can’t control the game. We didn’t try everything. We’re in treatment now,” he said.

Roblox CEO I advised my parents To keep children away from the platform if they feel worried. Maria, a mother of three from Berkshire, felt that her children were socially excluded when they were offline, making it difficult for parents to do so, and was among many who emphasized that they had unlocked the monetization elements of the platform – the higher game levels and personalization features, becoming a status symbol between the children.

In a statement, Roblox said: “We deeply sympathize with parents who described their children’s negative experiences at Roblox, which is not something we strive for and does not reflect the online civic space we want to build for everyone.

“Ten millions have positive, rich, safe experiences at Roblox every day in a supportive environment that encourages connection with friends, learning and developing important STEM skills.

Alphabet’s Google Parent Company makes historic purchase of cybersecurity firm Wiz

Alphabet, the owner of Google, has agreed to purchase Cybersecurity Group Wiz for $32 billion (£24.7 billion).

Google is acquiring an Israeli startup in an effort to compete with rivals Microsoft and Amazon in the cloud services market.

Wiz provides services that scan data from cloud storage providers like Amazon Web Services and Microsoft Azure for security risks. It previously turned down Alphabet’s $23 billion bid last summer.

However, concerns about regulatory approval caused some issues with the initial bid.

If the deal falls through, Alphabet has agreed to pay a $3.2 billion fee. This acquisition indicates a test of the Trump administration’s willingness and shows President Biden’s leadership in acquiring major technology companies.

Alphabet is currently facing pressure from US Department of Justice officials to sell off its Chrome browser to address concerns about its dominance in the search market.

Wiz, founded in 2020 by graduates of the Israeli Intelligence Corps, has offices in New York and Israel, with its European headquarters in London.

Despite the acquisition, Wiz will operate independently from Google, similar to how Microsoft operates LinkedIn.

Wiz will continue to collaborate with major cloud platforms such as Amazon Web Services, Microsoft Azure, and Oracle Cloud.

Alphabet, Google’s Parent Company, Fails to Impress Wall Street with Revenue Amid Tough AI Competition

Alphabet, Google’s parent company, saw a drop of over 6% following the release of its quarterly results on Tuesday. The company reported revenue of $96.5 billion, slightly below analysts’ expectations of $96.67 billion. While Alphabet exceeded investors’ earnings per share (EPS) expectation of $2.13 by reporting $2.15, the company highlighted a strong fourth quarter led by AI advancements and overall business momentum.

Revenue breakdown included $84 billion from Google Search and services, with $12 billion from YouTube advertising and cloud revenue. Analysts are closely watching Alphabet’s competitive position in AI search and cloud revenues amidst growing competition from players like Chinese DeepSeek and OpenAI.

The company’s deceleration reflects a challenging year for Google, raising concerns about its future competitiveness. Alphabet plans to invest $750 billion in capital spending in the coming year to further develop AI and infrastructure.

Despite ongoing AI development efforts across the industry, Alphabet remains focused on AI innovation with a significant investment plan. The company aims to leverage its AI capabilities for monetization in the coming years.

Concerns about rising AI costs and their impact on Alphabet’s AI advertising strategy have emerged in light of recent developments. Analysts are closely monitoring how these developments will shape Alphabet’s future AI initiatives and competitiveness.

Additionally, Alphabet remains committed to responsible AI development practices, emphasizing the importance of democracy, human rights, and global cooperation in AI leadership. The company reaffirms its commitment to using AI for positive impact and national security.

Legal challenges, including antitrust investigations, pose further uncertainties for Alphabet’s future. The Ministry of Justice’s case against a major search company raises concerns about potential regulatory actions that could affect the tech industry.

In light of geopolitical tensions, particularly with China, Alphabet faces additional challenges as regulatory scrutiny intensifies. China’s response to tariff announcements and antitrust investigations adds to the uncertain outlook for Google.

New research suggests WASP-121B may have originally formed much closer to its parent star than previously thought.

Astronomer using Immersed lattice infrared flash device (IGRINS) Gemini South Telescope devices looked at Wasp-121B, one of the most widely studied Ultra Hot Jupiter.

The artist's illustration indicates Wasp-121B, an alien world that has lost magnesium and iron gas from the atmosphere. Image credit: NASA / ESA / J. OLMSTED, STSCI.

WASP-121B, discovered by astronomers using Wasp-South Survece in 2016, is 1.87 times that of Jupiter, 1.18 times large.

The host star, WASP-121 (TYC 7630-352-1) is an active F6 main sequence star about 1.5 times the size of the sun.

The WASP-121 system is about 881 light-years away to the puppy constellation.

WASP-121B is a so-called “hot jupiter” and takes only 1 for three days to get on WASP-121 on track. As it is very close to the parent's star, as it approaches, the gravity of the star begins to tear.

Astronomers estimate that the temperature of the planet is about 2,500 degrees (Hana 4,600 degrees), which is enough to boil some metals.

The new Iglin observation results have revealed something unexpected about the WASP-121B formation history.

With these observations, Peter Smith and his colleagues at the Arizona State University, for the first time, measured the ratio of passenger rocks and ice using a single instrument.

“Gemini South using IGRINS has actually measured individual chemical existence more accurately than even achieving a space -based telescope,” said Smith.

The spectroscopic data indicates that the WASP-121B has a high ratio of rock and ice, and indicates that excessive rocky materials have been accumulated during the formation.

This suggests a planet formed in the area of ​​the protranetary disk that is too hot for the ice to condense.

“Our measurement means that this typical view must be reconsidered and the planetary formation model needs to be revisited,” Smith said.

Astronomers also discovered a remarkable feature of the WASP-121B atmosphere.

“The climate of this planet is extreme, not the earth's climate,” Smith said.

Since the planet daySide is very hot, elements that are generally considered “metal” evaporate in the atmosphere and can be detected by the spectroscopic method.

The strong wind blows these metals into the permanent night side of the planet. There, it is cool enough to condense and rain. This is an effect observed on Wasp-121B in the form of calcium rain.

“The sensitivity of our device can be used to examine the subtle wind speed by examining various areas, altitude, and long terms using these elements, revealing how dynamic this planet is. You can do it, “said Smith.

Survey results Will be displayed in Astronomy Journal

Wizz, a cybersecurity company, turns down $23 billion acquisition bid from Alphabet Inc., Google’s parent company

Cybersecurity company Wizz has turned down a $23bn (£18bn) takeover offer from Google’s parent Alphabet, making it the largest takeover bid ever for a tech company, and has opted for a stock market listing instead.

Alphabet had been in discussions with Wizz, a company established by graduates of Israel’s cyber-intelligence program, in an effort to catch up with competitors Microsoft and Amazon in the competitive cloud-services market.

Wiz provides a service that scans data on cloud storage platforms like Amazon Web Services and Microsoft Azure for potential security threats.

The New York-based startup, which is financially backed by investors such as Sequoia Capital and Thrive Capital, was last valued at $12 billion.

In an internal email to employees, the company expressed gratitude for the offer but decided to remain committed to its mission of building Wiz. CEO Assaf Rapaport outlined the company’s objectives of reaching $1 billion in annual recurring revenue and going public.

Despite the tempting offer, the company’s trust in its skilled team reaffirmed their decision. The positive response from the market further reinforced their aim to create a platform that is loved by both security and development teams.

As of Tuesday morning, neither Wizz nor Google have released an official statement regarding the end of the acquisition negotiations.

There are concerns that the deal may face regulatory challenges as authorities seek to tighten their control over acquisitions involving major tech companies.

Last month, the US Department of Justice and the Federal Trade Commission agreed to investigate leading players in the AI market, including Microsoft, OpenAI, and Nvidia.

Established in 2020, Wizz was valued at $12 billion in a funding round in May, attracting investments from Andreessen Horowitz, Lightspeed Venture Partners, and Thrive.

Wiz claims to have 40% of the Fortune 100 as clients and boasts an annual recurring revenue of $350 million.

TikTok’s parent company, ByteDance, argues that the US’s alleged discrimination against the popular app is unconstitutional

ByteDance, a Chinese tech company, has filed new legal documents challenging the US government’s “unconstitutional discrimination against TikTok.” These documents also reveal details about failed negotiations regarding a ban on the platform.

A legislation signed by President Joe Biden in April requires ByteDance to sell TikTok’s U.S. assets by Jan. 19 or face a ban. ByteDance argues in its filing that such a sale is “technically, commercially, and legally impossible.” The company accuses the US government of not taking settlement negotiations seriously after 2022.

TikTok, in a lawsuit, states, “Never before has Congress silenced so much speech with a single act.”

The proposed ban reflects long-standing national security concerns from US lawmakers who fear China could exploit the app to access Americans’ data or spy on them. While the Biden administration prefers ByteDance to sell TikTok instead of an outright ban, the company claims it’s not a viable option.

The bill would prevent app stores like Apple and Google from featuring the app unless ByteDance sells it. It would also prohibit internet hosting services from supporting TikTok without a sale, effectively banning its use in the US.

In its filing, ByteDance’s lawyers outline the company’s negotiations with the US government, which abruptly ended in August 2022. The company also shared a redacted draft national security agreement aimed at protecting TikTok’s US user data.


The proposed agreement includes a “kill switch” for the US government to halt TikTok’s use in the US if it doesn’t comply. The US has also requested TikTok to move its source code out of China.

TikTok’s lawyers criticized the administration for favoring shutting down TikTok in the US instead of working on a practical solution to protect US users. The Justice Department defended the law, saying it addresses national security concerns while respecting constitutional constraints.

TikTok and ByteDance filed a lawsuit in the United States Court of Appeals for the District of Columbia Circuit on Sept. 16. The outcome of the case could influence the government’s use of new powers against foreign-owned apps.

TikTok argues that separating businesses is not feasible and claims the law violates free speech rights. The platform’s content creators maintain that there is no imminent national security threat, as the law allows TikTok to operate for the remainder of the year.
