NASA’s Jet Propulsion Lab is reportedly holding a “going out of business sale” for its satellites, NASA Watch reports.
The list of for-sale assets includes several Earth-monitoring satellites that were once tasked with studying the environment, helping with hurricane prediction efforts, and measuring the effects of climate change. Most launched over the last 20 or so years.
Others, such as the Geostationary Littoral Imaging and Monitoring Radiometer (GLIMR) instrument, have yet to be launched.
According to NASA Watch, a blog run by former NASA astrobiologist Keith Cowing, the satellites were originally “targeted for shut down” in the Trump administration’s 2026 budget request.
The budget drew the ire from lawmakers earlier this year, proposing to cut NASA’s science directorate’s budget by more than half, in “nothing short of an extinction-level event for space science and exploration,” per The Planetary Society’s chief of space policy, Casey Dreier.
However, “NASA HQ is apparently not waiting for an actual budget,” according to Cowing, and is going ahead with the satellite shutdowns anyway, a troubling sign of extremely difficult days ahead for the space agency.
None of this should come as much of a surprise. The Trump administration has been looking to decimate the government’s efforts to study the environment, highlighting the president’s well-documented climate change denial and ruthlessly anti-science agenda.
Deals! Deals! Deals!
Per NASA Watch, JPL is now trying to offload the satellites to “government and private sector buyers” in an apparent effort to raise funds.
When asked for more details, Cowing said that it’s an “evolving story,” adding that “I post what I know and can confirm as soon as I can.”
The news was met with exasperation by the scientific community, including members currently employed by the space agency.
“We got to keep a sense of humor these days at JPL,” JPL senior engineer Luis Amaro wrote in a LinkedIn post, in response to Cowing’s “going out of business sale” wording.
“The American people voted for this,” Yusef Johnson, mission integration lead of NASA’s Artemis IV mission, added. “Snake oil still sells.”

Six-star Gigantamax Battles in Pokémon GO are notoriously challenging, with each battle requiring between 20 and 40 Trainers to secure a victory. Because of this, it’s a good idea to build your battle team before the event. As a Water- and Ice-type Pokémon, Lapras is vulnerable to Electric-, Grass-, Fighting-, and Rock-type attacks. Trainers can only use Dynamax or Gigantamax Pokémon in Gigantamax Battles, and it’s important to choose Pokémon equipped with these types of attack.
While Gigantamax Pokémon have a fixed G-Max attack, Dynamax Pokémon have a Max Move attack type that matches their Fast Attack type. So, if you have Dynamax Pokémon that you think would be a good Gigantamax Lapras counter, be sure they know an Electric-, Grass-, Fighting-, or Rock-type Fast Attack. Leveling up your team’s attacks prior to battle will help ensure that they deal maximum damage when they face their powerful foe. Leveling up and evolving your Pokémon prior to Gigantamax Lapras Max Battle Day will also allow you to focus on taking on as many Gigantamax Lapras battles as possible.
Max Pokémon that might make a good counter to Gigantamax Lapras include these Dynamax Pokémon: Venusaur, Machamp, Zapdos, Raikou, Passimian, Rillaboom, Toxtricity, and Falinks. Strong Gigantamax counters are Venusaur, Machamp, Rillaboom, and Toxtricity.

Everyone’s favorite rambunctious little blue alien has crossed an important milestone.
The Walt Disney Studios’ live-action reimagining of Lilo & Stitch has officially crossed the $1 billion mark at the global box office, making it the first Motion Picture Association (MPA) title of 2025 to reach the milestone. The film now stands as the #1 MPA release of the year both globally and internationally.
This achievement marks a significant moment for Disney, which has now delivered four billion-dollar films in the past 13 months. Alongside Lilo & Stitch, the studio’s recent billion-dollar hits include Moana 2 from Walt Disney Animation Studios, Marvel Studios’ Deadpool & Wolverine, and Disney and Pixar’s Inside Out 2.
“We knew there was a lot of love for Lilo & Stitch with audiences around the world, yet we never take that for granted, and we’re proud of how this new film has connected with people,” Alan Bergman, Co-Chairman of Disney Entertainment, said. “I’m thankful to our filmmakers, our cast, and all on our Studio team who have made this film such a success, and we look forward to more adventures with these characters ahead.”
Domestically, Lilo & Stitch opened with a staggering $183 million over four days, setting a new record for the biggest Memorial Day weekend debut in history. It is one of only two films this year to surpass $400 million at the North American box office.
The film’s success has reignited global interest in the Lilo & Stitch franchise. Viewership of the original 2002 animated film and related content on Disney+ has surged, with more than 640 million hours streamed globally. A sequel to the live-action film is already in development.
“Stitch is an example of what Disney actually does best,” David Greenbaum, President of Disney Live Action and 20th Century Studios, said in May. “An extraordinary animated film from 2002 that becomes a series that then over time creates a real fanship, which leads to us looking at the idea of creating this wonderful film that we now are bringing out to the world.”
Lilo & Stitch’s performance underscores the studio’s continued box office dominance as well as its ability to revitalize beloved classic stories for new generations. The film’s success also reinforces the global reach of the Disney brand showcasing the company’s ability to craft stories that touch multiple parts of Disney’s businesses from theatrical to streaming to experiences to consumer products.
Chris Martin, the lead singer of Coldplay, called out a couple who hid their faces after being caught on a kiss camera during a show on Wednesday, saying they looked like they were having an affair.
A blonde woman and a man with grey hair were spotted embracing on the big screen at the Gillette Stadium during the Massachusetts stop of Coldplay’s world tour.
Video of the moment, which was shared online, shows the pair appearing on screen. As they realize they’re being broadcast to the entire stadium, the woman covers her face with her hands and the man ducks completely out of frame.
“Oh, look at these two. You’re alright. You’re OK. Oh, what? Either they’re having an affair or they’re just very shy,” Martin joked.
The clip of the pair quickly spread across social media platforms like X and TikTok, where they racked up millions of views and thousands of comments.
Online sleuths named two people they believed to be the pair on screen. However, NBC News has not been able to independently verify the identity of the couple.

J.Lo is bound for Kazakhstan and it’s a signal of Russia’s declining influence in Central Asia. Okay, let’s not plant an American flag just yet – this concert may not be part of a State Department strategy to increase US soft power in the energy-rich region, but rather a last-ditch effort by a somewhat faded pop icon Jennifer Lopez to wring the last dollars from her career.
But did you also hear the Backstreet Boys will be performing in Uzbekistan?
The Westernisation of Central Asia is a notable cultural phenomenon. Music can serve as a powerful instrument for great powers to expand their influence in certain parts of the world. In Central Asia, a region traditionally within Russia’s geopolitical orbit, the United States seems to be slowly winning hearts and minds through pop music – whether by design or by a twist of circumstances.
Russian singers seem to have a hard time balancing their political views with their careers, especially if they aim to perform in what Moscow sees as its near abroad.
American bands and singers performing in the strategically important region is nothing new. Back in 2009, the North Carolina-based Brian Horton Quartet played a series of concerts in Uzbekistan. That same year, another jazz group, the Ari Roland Quartet, toured Central Asia, while in 2019 the rock band Aberdeen performed in Kyrgyzstan. Four years later, Kanye West performed at the wedding of the grandson of then Kazakh President Nursultan Nazarbayev in Almaty.
But apart from the famous rapper, most American bands that have played in Central Asia over the past 15 years were not globally popular. That will change with the high-profile acts scheduled to play in the region in the coming months.
These performances come as regional states seek to establish deeper political, economic, and even military ties with the West. The fact that Jessica Lynn, a country artist from New York, is set to perform in Turkmenistan – one of the most closed nations in the world – perfectly illustrates that even Ashgabat has begun to gradually follow other former Soviet republics in developing closer relations with the United States and European powers.

Russia’s declining influence in the region accelerated when its nominal allies started turning their backs on Moscow following the Russian invasion of Ukraine in 2022. However, the region’s Soviet past has undoubtedly left a deep mark on its culture. Although Hollywood movies and American pop music dominate globally, local artists and Russian stars still maintain a strong presence in Central Asia. That is why, more than three decades after the collapse of the Soviet Union, Russian musicians remain very popular in Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan, and Turkmenistan.
But while some Russian singers and bands freely perform in Central Asia, attracting thousands to their concerts, musicians who openly supported the Kremlin’s actions in Ukraine have been banned from playing there. Russia’s oldest still-active rock band, Mashina Vremeni, received threats ahead of its concerts in Kyrgyzstan in 2023, because its founder, Andrey Makarevich, while condemning Russia’s actions in Ukraine, expressed support for Israel’s actions in Gaza.
His fellow performer Morgenstern also found himself in a difficult position. Recognised as a foreign agent at home, where he faces up to two years in prison, he was labelled a “bad influence” on young people in Kyrgyzstan, which is why he had to cancel his concerts in the landlocked Central Asian state. Russian singers, therefore, seem to have a hard time balancing their political views with their careers, especially if they aim to perform in what Moscow sees as its near abroad.
American musicians, on the other hand, do not seem to face such challenges. Their growing presence in Central Asia resembles socialist Yugoslavia’s opening toward the West, following the country’s 1948 split from the Soviet sphere of influence. Nowhere was that break more visible than in the field of pop culture.
In the mid-1950s, American jazz performers such as Louis Armstrong, Dizzy Gillespie, and Dave Brubeck, among others, played in Yugoslavia, which contributed to the growing popularity of jazz music – and later, rock ‘n’ roll – in the country. It was, therefore, no surprise that in 1974, amid the Cold War, Tina Turner performed in Belgrade, marking the beginning of a trend that saw popular American musicians regularly tour the Balkan nation throughout the 1980s and up to its breakup in 1991.
But unlike Central Asian states, Yugoslavia was never part of the Eastern Bloc, let alone the Soviet Union. That is why Soviet cultural influence in the country remained limited, while growing Western presence led to the emergence of the Yugoslav rock ‘n’ roll scene. In Central Asia, the region’s Soviet legacy means that American musicians, for the foreseeable future, are likely to face strong competition from Russian performers.
After more than a decade as a fashion designer, Dana Cohen was disillusioned. Excessive waste was rampant in every part of the industry – from surplus samples, to manufacturing scraps, to retail stores with “a disheveled mountain of garments that nobody wanted”, she said. “I was like, ‘I just don’t want to be a part of it any more.’”
Then Cohen, who had designed for brands including Banana Republic, Club Monaco and J Crew, had a chance encounter with a manufacturer that changed her course. Drishti Lifestyle, based in India, had a container full of leather scraps it didn’t want to discard. Together they experimented, and made some wallets and a handbag, all of which sold out. That was the very start of Cohen’s sustainable leather accessories company – and her mission to make a dent in the industry’s immense waste problem.
Launched in November 2019, Hyer Goods sells bags, wallets and other accessories made entirely from deadstocks: leftover scraps that would otherwise end up in landfills. Specifically, it uses luxury leather leftovers, retrieved from designer heavyweights like Hermes, Chanel, and Valentino. Deadstocks are sourced both directly from Italian factories – such as a tannery in the outskirts of Naples, Russo di Casandrino – and via “people on the ground” in Italy who have longstanding relationships with those brands.

The scraps are then transported to family-run factories in Italy’s Marche region, on the Adriatic coast: a mother-daughter-run factory produces the bags, and down the road, a father-son-run-factory assembles the wallets. “We literally load the scraps from the bags in a little car and drive it to the wallet factory,” Cohen said.
Designer brands typically only use the very highest grades of leather, so Hyer takes the “off-cuts” that are still above par, but may have blemishes like tick bites or stretch marks, and cuts around them.
Given the reliance on whatever is available, the Hyer collection is inherently small-batch, and a single line of bags might comprise a mix of different leathers. “We have never made 500 pieces of anything,” Cohen said.
The unpredictable supply can be hard. “It’s not for the faint of heart,” Cohen said. But she estimates this model has kept approximately 7,000 pounds of leather in circulation – and out of landfills – over the last six years of operation.
It’s a start in healing an industry that sends some 92m tonnes of textiles to landfills every year, producing between 4% and 8% of the world’s greenhouse gas emissions.
“I appreciate any company that’s really trying to work towards the circular economy,” said Ann Cantrell, associate professor of fashion business management at New York’s Fashion Institute of Technology (FIT), “which is trying to keep things in the loop as long as we can and not go to landfill.” She said Hyer Goods’s model follows the “triple bottom line”: operating not only for profitability, but also for improving conditions for people and for the planet. If more businesses operate with such models, they can “continue to challenge the status quo” around issues like the overuse of virgin materials, she said.
Leather is particularly troublesome for its connection to cattle ranching, which is linked to deforestation, mass water use, and the emission of methane, a potent greenhouse gas. Tanning also uses toxic chemicals that can contaminate waterways. On the other hand, leather is an extremely durable product, sometimes lasting decades. “So from that perspective, it is a sustainable material,” said Cantrell.
Sustainability is nuanced. “There’s no perfectly sustainable material,” said Elizabeth Cline, an author and expert on fast fashion and sustainability. But Cline said repurposing genuine leather is better than producing so-called vegan leather, or faux leather, which is made of plastics, even when it also contains some plant-based materials like cork or apple peels. “You’re eliminating the animal welfare issue, but creating new environmental problems,” she said.
The reality is that high-end consumers are still buying genuine leather. While Hyer’s average customer is the sustainable-minded person looking for greener alternatives, Cohen said she is starting to see more luxury-driven customers.

Hyer’s bestselling Ring Bag, made from lambskin Nappa, a premium leather known for its softness, typically sells for $465 – nothing to sneeze at but still a far cry from luxury brands that retail for several thousand dollars.
Cohen launched Hyer Goods just months before the pandemic.People weren’t buying fancy handbags during lockdowns so she briefly pivoted to sewing masks with leftover fabrics – even curtains – that she crowdsourced on social media. Consulting followers for opinions has continued to be a strategy. “I think people really like being a part of the process,” she says. “Not only is it a great way to connect with community, but it’s a really good way to make smart decisions.”
Soon, the bags gained the attention of influential figures like Katie Couric and internet chef Alison Roman. When Roman recommended the bags to her followers: “That was one of the best days for us, ever,” Cohen said.
Major brands like Bloomingdales, Nordstrom and Madewell now sell Hyer Goods bags, and in 2024, Cohen opened a brick-and-mortar store in New York’s West Village after winning a grant from the nonprofit ChaShaMa, which supports women and minority artists by providing them with subsidized real estate spaces.
Beginning April, the Trump administration imposed 10% tariffs on goods from Italy, leaving Cohen little choicebut to raise prices. The price bumps initially led to a “huge dip” in sales, she said. Volumes seem back to normal now, though that’s hard to parse out due to seasonal shifts. “I’m not sure if the customer has gotten used to it, but I certainly haven’t,” she said. (In July, Trump announced additional tariffs on European goods, which European trade officials said would make continuing US-EU trade ““almost impossible”.)

Cohen said she has no plans to move operations to the US; many factories that she had considered weren’t capable of details like edge painting (to protect leather edges from fraying), which would sacrifice quality. “The craftsmanship that you can get in Italy just doesn’t compare,” she said. “‘Made in USA was just not an option.”
Cohen, who has five part-time employees, said she’d like to expand products into belts and shoes, start sourcing deadstock Italian cottons, and open a second store, perhaps in Brooklyn. She’d like to be fully circular, including hardware like zippers, which are not made from scraps.
But economic volatility – and simply the nature of a bootstrapped business that depends on a fluctuating supply – have delayed some of those plans. “Any dreams I had, I’ve put on hold,” she said. “Right now it’s just: how can we stay afloat?”
But nothing has changed her mission, which comes before any growth ambitions, she said. “My goal was never to be a behemoth organization,” Cohen said. “I just want to have a nice, small business for people who care.”
Liver organoids with proper blood vessel networks have been successfully produced, as reported by researchers from Institute of Science Tokyo and Cincinnati Children’s Hospital Medical Center. This advancement addresses a major challenge in replicating the liver’s complex vasculature in lab-grown tissues. Using a novel 3D culture system, the researchers achieved the self-organization of four distinct precursor cell types into functional organoids, capable of producing essential clotting factors in a haemophilia A mouse model.
Over the past decade, organoids have become a major focus in biomedical research. These simplified, lab-grown organs can mimic important aspects of human biology, serving as an accessible and powerful tool to study diseases and test drugs. However, replicating the intricate arrangements and networks of blood vessels found in real organs remains a major hurdle. This is especially true for the liver, whose metabolic and detoxification functions rely on its highly specialized vasculature.
Because of such limitations, scientists haven’t fully tapped into the potential of liver organoids for studying and treating liver diseases. For example, in hemophilia A, a condition where the body cannot produce enough of a critical clotting factor, current treatments often involve expensive and frequent injections. An ideal long-term solution would restore the body’s ability to produce its own clotting factors, which could, in theory, be achieved using liver organoids with fully functional blood vessel structures called sinusoids.
In a recent study, a research team led by Professor Takanori Takebe from the Institute of Integrated Research at Institute of Science Tokyo (Science Tokyo), Japan, and Cincinnati Children’s Hospital Medical Center, USA, has successfully created the world’s first liver organoids containing authentic sinusoidal-like blood vessels. Their study, published online in the journal Nature Biomedical Engineering on June 25, 2025, describes a novel culture method that enables four different types of progenitor cells to self-organize into functional liver organoids.
First, the researchers established a technique to reliably produce liver sinusoidal endothelial progenitors (LSEPs) from human-induced pluripotent stem cells, something that had been proven difficult in previous studies. They achieved this through a careful cultivation protocol and a timely analysis of key transcriptional changes that occur as stem cells differentiate into endothelial cells.
After this, the researchers developed an innovative 3D culture method called inverted multilayered air–liquid interface (IMALI), which involves arranging multiple cell types in a specialized gel environment. When cultured using the IMALI method, hepatic endoderm cells, mesenchymal cells, arterial endothelial cells, and LSEPs self-organize into dome-shaped liver organoids approximately 3 mm in diameter.
Through detailed genetic analysis, the team discovered that these organoids developed four distinct types of blood vessel cells, with sinusoidal vessel cells becoming dominant over time.
This technique provides a foundational method for embedding organ-specific vascular structures into organoids, contributing to the understanding of human biology and disease.”
Professor Takanori Takebe from the Institute of Integrated Research at Institute of Science Tokyo
Most importantly, the organoids could accurately replicate some key liver metabolic functions, including the stable production of clotting factors. When transplanted into a hemophilia A mice model, the organoids significantly improved bleeding symptoms for up to 5 months. Favorable results were also obtained in tests with human plasma samples from people with coagulation deficiencies.
These findings underscore the true potential of properly vascularized organoids, as Takebe remarks, “Our enhanced organoids may support the development of regenerative therapies for coagulation disorders and end-stage liver failure, as well as drug discovery and disease modeling.” This technology could lead to advances in personalized medicine, where organoids grown from a patient’s own cells could be used to provide tailored treatments or serve as testing platforms for assessing drug responses.
The research team plans to further explore the applications of these liver organoids and evaluate their long-term stability and safety for clinical use. Further efforts could even extend insights derived from this study to other types of organoids.

Early risers will get a rare opportunity to see something extraordinary in the early hours of July 18 — the dark shadow of Saturn’s largest moon, Titan, sweeping across the planet’s cloud tops.
Once every 15 years, Saturn’s tilted orbit brings its iconic rings — and Titan’s orbital path — into an edge-on alignment with Earth. This event, known as a ring-plane crossing, heralds the onset of a season of dramatic ‘shadow transits’, as Titan’s vast umbral silhouette periodically sweeps across the gas giant’s surface.
“Sighting a shadow transit of Titan for an amateur astronomer is somewhat the equivalent of a fisherman hooking and reeling in a particularly large or elusive fish,” Hayden Planetarium instructor and lecturer Joe Rao told Space.com in an email. “It is so unusual a sight that doesn’t happen very often, which is why even veteran skywatchers are excited at the possibility of making such a sighting.”
When is Titan’s shadow transit?
Titan’s next shadow transit will get underway at 3 a.m. EDT (0700 GMT) on July 18, at which time the moon’s dark outline will be visible slowly progressing across Saturn’s cloudy disk, according to Sky and Telescope.
Look for Saturn in the southeastern sky, just below the stars of the constellation Pisces shining like a bright star to the naked eye, with the moon in the east.
Observers in the U.S. will have a good view of the first two hours of the shadow transit, but by the time Titan’s shadow leaves Saturn’s disk at 8:05 a.m. EDT (12:05 GMT), the brightening dawn will overpower the view.
How powerful does a telescope need to be to spot Titan’s shadow?
At the time of the shadow transit, Titan and Saturn will be separated by approximately 846 million miles (1.36 billion kilometers) from Earth — far beyond the capabilities of the naked eye or binoculars, but well within reach of many amateur telescopes.

We asked Rao for guidance on the kind of scope needed to view Titan’s shadow transit. “An 8-inch telescope at 200-power or a 10-inch telescope at 250-power should provide a good view of Titan’s shadow, especially on a night of good seeing,” Rao explained.

To calculate the magnifcation of your telescope, you need only divide its focal length by the focal length of your chosen eyepiece. For example, a 1000 mm telescope with a 10 mm eyepiece yields 100-power magnification.
Rao also emphasised that stable atmospheric conditions are crucial to obtaining a clear view. This becomes more important when using higher power with a smaller aperture scope. It’s best to use one-half magnification/power when viewing distant objects to avoid them appearing to “boil”, or “scintilate” when viewed through the eyepiece.
“At least 200-power is necessary for getting a reasonably good view of the dark ‘shadow dot’ projected on Saturn’s disk,” continued Rao. “The general rule of thumb is to utilize 50-power for every inch of aperture of the telescope objective, or mirror. So, for a 4-inch telescope, the maximum magnification to be used is 200-power, which is considered the limit for a telescope of that size.”
When are the next Titan shadow transits?
After the July 18 event, five more Titan shadow transits will be visible from Earth. Each occurs roughly16 days after the last — a result of Titan’s 16-day orbital period — and starting progressively earlier in the night for viewers in the U.S.

The next transit after this week will begin at 2:25 a.m. (0625 GMT) on August 3, while the last chance to catch the moon’s shadow fall on Saturn will take place on October 6.
After the October event, stargazers will have to wait another 15 years before the next ring crossing brings Titan — and its shadow — into alignment once more!
Titan’s shadow through the eyes of the Cassini spacecraft
Without question, the most spectacular views of a Titan shadow transit came courtesy of NASA’s Cassini spacecraft, which witnessed the moon’s dark outline fall over Saturn’s cloud surface in November 2009, while it travelled a mere 1.3 million miles (2.1 million km) from the colossal gas giant. Cassini has long since found its resting place beneath the cloud surface of Saturn, but amateur astronomers will have an opportunity to follow in Cassini’s steps later this week and witness the next Titan shadow transit for themselves when it takes place on July 18.
“Though we, living in the 21st century, have grown accustomed to seeing the Saturnian system through the eyes of Cassini, there still remains the thrill of witnessing, with one’s own eyes, a major celestial event in the life of another planet a billion miles away,” Carolyn Porco, planetary scientists and imaging team leader for NASA’s Cassini mission told Space.com in an email.
