Beth Shapiro
Beth Shapiro, chief science officer of Dallas-based Colossal Biosciences, might be most famous for the company's current controversial mission to de-extinct the woolly mammoth in 2028. Colossal made news in April with the announcement that it had used genetic engineering to bring back the ancient dire wolf, and it intends to do the same for other species, including the dodo and the Tasmanian tiger. But Shapiro, who specialized in ancient DNA research at Oxford University, Penn State University, and elsewhere, also uses her gene-editing skills to help protect endangered species like the red wolf and the Asian elephant. The same genetic engineering tools behind the de-extinction of vanished species can be used to breed hardiness or greater genetic variety into existing ones threatened with extinction.
Shapiro believes that we owe this to both the Earth and to ourselves. "Conservation isn't just about saving species, but about maintaining the ecological conditions that protect human health," she wrote to TIME, noting that the ecosystem collapse that results from extinction also breeds animal diseases that have been known to jump to humans. Beyond that, the science she is leading at Colossal has applications in human health. Her team uses organoid models to experiment with the effects of gene editing on real tissue outside of a living animal—but that can also be done for humans.
"Vascularized organoids develop into complex structures that are physiologically relevant models for studying diseases," she says. "Because they can be grown from a particular individual, [they can be used for] testing personalized treatments for cancers and other diseases."

Elon Musk promises more risky launches after sixth Starship failure
When you buy through links on our articles, Future and its syndication partners may earn a commission. This article was originally published at The Conversation. The publication contributed the article to Expert Voices: Op-Ed & Insights. This was the ninth test flight for the rocket, and the third catastrophic failure in a row, just this year. Is this what we should expect from the very ship some are counting on to take humans further than we've ever been in the solar system? Or does this failure point to deeper concerns within the broader program? A decade of development The Starship program from Elon Musk's space technology company, SpaceX, has been in development for more than a decade now and has undergone many iterations in its overall design and goals. The Starship concept is based upon the SpaceX Raptor engines to be used in a multistage system. In a multistage rocket system, there are often two or three separate blocks with their own engine and fuel reserves. These are particularly important for leaving Earth's orbit and travelling to the Moon, Mars and beyond. With Starship, the key factor is the ability to land and reuse vast amounts of the rocket stages again and again. The company's Falcon 9 vehicles, which used this model, were fantastically successful. Initial tests of Starship began in 2018 with two low-altitude flights showing early success. Subsequent flights have faced numerous challenges with now four complete failures, two partial failures and three successes overall. Just two days ago, during the latest failed attempt, I watched alongside more than 200 other space industry experts at the Australian Space Summit in Sydney. Broadcast live on a giant screen, the launch generated an excited buzz – which soon turned to reserved murmurs. Of course, designing and launching rockets is hard, and failures are to be expected. However, a third catastrophic failure within six months demands a pause for reflection. On this particular test flight, as Starship positioned itself for atmospheric re-entry, one of its 13 engines failed to ignite. Shortly after, a booster appeared to explode, leading to a complete loss of control. The rocket ultimately broke apart over the Indian Ocean, which tonnes of debris will now call home. Polluting Earth in pursuit of space We don't know the exact financial cost of each test flight. But Musk has previously said it is about US$50–100 million. The exact environmental cost of the Starship program – and its repeated failures – is even harder to quantify. For example, a failed test flight in 2023 left the town of Port Isabel, Texas, which is located beside the launch site, shaking and covered in a thick cloud of dirt. Debris from the exploded rocket smashed cars. Residents told the New York Times they were terrified. They also had to clean up the mess from the flight. Then, in September 2024, SpaceX was fined by the US Environmental Protection Agency and the Texas Commission on Environmental Quality for 14 separate incidents since 2022 where the launch facilities discharged polluted water into Texas waterways. Musk denied these claims. That same month, the US Federal Aviation Administration (FAA) proposed a fine of US$633,009 in civil penalties should be issued to SpaceX. This was on the grounds of using an unapproved launch control room and other violations during 2023. Musk denied these claims too and threatened to countersue the FAA for 'regulatory overreach'. It's unclear if this suit was ever filed. Two other failed launches in January and March this year also rained rocket debris over the Caribbean, and disrupted hundreds of commercial flights, including 80 which needed to be diverted and more than 400 requiring delayed takeoff to ensure they were entering safe air space. Success of different space programs Until last year, the FAA allowed SpaceX to try up to five Starship launches a year. This month, the figure was increased to 25. A lot can go wrong during a launch of a vehicle to space. And there is a long way to go until we can properly judge whether Starship successfully meets its mission goals. We can, however, look at past programs to understand typical success rates seen across different rocketry programs. The Saturn V rocket, the workhorse of the Apollo era, had a total of 13 launches, with only one partial failure. It underwent three full ground tests before flight. SpaceX's own Falcon 9 rocket, has had more than 478 successful launches, only two in flight failures, one partial failure and one pre-flight destruction. The Antares rocket, by Orbital Sciences Corporation (later Orbital ATK and Northrop Grumman) launched a total of 18 times, with one failure. The Soyuz rocket, originally a Soviet expendable carrier rocket designed in the 1960s, launched a total of 32 times, with two failures.

Its goals are certainly novel as a reusable heavy-class rocket. But this latest failure does raise some questions. Will the Starship program ever see success – and if so when? And what are the limits of our tolerance as a society to the pollution of Earth in the pursuit of the goal to space? For a rocketry program that's moving so fast, developing novel and complex technology, and experiencing several repeated failures, many people might expect caution from now on. Musk, however, has other plans. Shortly after the most recent Starship failure, he announced on X (formerly Twitter), that the next test flights would occur at a faster pace: one every three to four weeks.

There's a hidden rule that all life on Earth must follow, research claims
If you purchase an independently reviewed product or service through a link on our website, BGR may receive an affiliate commission. Life on Earth is complex and hard to understand, but new research may have finally given us a much-needed glimpse into the patterns that life follows as it spreads across our planet. According to a new study published in Nature Ecology & Evolution, researchers believe life has a hidden rule that it has to follow, and the signs of that rule can be found in every bioregion across our planet. This rule, the researchers claim in their new paper, could help us explain why no matter how different every environment on our planet is, every bioregion seems to follow the same design. It could also help us better understand how the ecosystems around the world respond to environmental changes like global warming. Today's Top Deals Best deals: Tech, laptops, TVs, and more sales Best Ring Video Doorbell deals Memorial Day security camera deals: Reolink's unbeatable sale has prices from $29.98 Just looking at life on Earth as a whole, it's easy to see the oceans and other natural barriers as end points for the patterns that drive life. However, researchers say they have found evidence of life's hidden rule in multiple regions, no matter how far apart they are. No matter what the region is, or what the environment is, they say that life always follows the same pattern. For starters, life seems to radiate from a single core area in each bioregion. Then, other parts of life like animals or plants will spread out from that core. Some thrive while others don't. It seems, the researchers write, that these core areas provide the optimal conditions needed for species to survive and diversify. From there, the rest of the region's biodiversity radiates outward. This new research supports previous findings that small areas play a disproportionate ecological role in sustaining the biodiversity found in different bioregions. It also could help us with conservation efforts, which often require finding the best place to put a species so it can thrive under human protection. Additionally, this evidence seems to show that life's hidden rule is indeed true. It plays into a previous theory that there are plausible mechanisms that drive the patterns life follows. While we might not know exactly how life on Earth started, we're slowly learning more about how it grew to be the massive, global phenomenon that it is today.

NASA's New Data Has Scientists Sounding the Alarm on Climate Extremes
The latest satellite data from NASA is painting a troubling picture of Earth's climate, and it's coming into focus faster than expected. According to new research from NASA's Goddard Space Flight Center, extreme weather events like floods and droughts are not only becoming more common, but also more intense, longer-lasting, and more destructive. The Guardian reported that data from the past five years show these events doubling in intensity compared to averages between 2003 and 2020. Even researchers behind the study admit they didn't anticipate such a dramatic spike. "We were surprised to find the actual population living in rural areas is much higher than the global data indicates," said lead researcher Dr. Bailing Li, who helped compile the figures using NASA's Grace satellite and dam relocation data across 35 countries. The result: a grim confirmation that climate change is fueling a shift in the planet's water systems, and the consequences are just data, which has not yet been peer-reviewed, reveals that global extremes now show a stronger correlation with rising temperatures than with other climate drivers like El Niño. Events are lasting longer, affecting wider areas, and shifting with less predictability—creating what scientists call "hydroclimatic whiplash," sudden transitions from drought to flood or vice versa. What's most worrying isn't just the scale of the change, but how unprepared most of the world remains. Experts say the current infrastructure, especially in water management, was built for a different era—one with a more stable climate. Christopher Gasson of Global Water Intelligence warned that most water systems are facing extremes from both ends—too much water or too little—and that investment must scale quickly to keep up. Meteorologists and climate experts across the globe echoed the concern. Richard Betts of the UK's Met Office called the data "a stark reminder" that what was once theoretical is now reality. He stressed that most societies have built their systems around past weather patterns, leaving them vulnerable to extremes that now fall outside the historical norm. With the World Meteorological Organization predicting an 80% chance that one of the next five years will be Earth's hottest ever, the window for adapting is narrowing. NASA's findings serve as a warning: the planet is heating up, and the consequences are already surging across every New Data Has Scientists Sounding the Alarm on Climate Extremes first appeared on Men's Journal on Jun 22, 2025
