From river-clogging plants to disease-carrying insects, the direct economic cost of invasive species worldwide has averaged about $35 billion a year for decades, researchers said Monday.
Since 1960, damage from non-native plants and animals expanding into new territory has cost society more than $2.2 trillion, more than 16 times higher than previous estimates, they reported in the journal Nature Ecology & Evolution.
The accelerating spread of invasive species —from mosquitoes to wild boar to tough-to-eradicate plants—blights agriculture, spreads disease and drives the growing pace of species extinction.
This is the weapon that will destroy our solar system in Season 3 of Netflix’s 3 Body Problem: the Dual-Vector Foil. It’s a Dimensional Strike deployed by a super advanced alien civilization called the Singers. Once activated, it expands at light speed, consuming everything in its path. It’s expected to be featured in Season 3 of Netflix’s 3 Body Problem series.
Plants that reproduce exclusively by self-pollination arise from populations with extremely low diversity to begin with. Kobe University research not only adds a facet to possible evolutionary strategies, but also lends weight to Darwin’s suspicion that this strategy might be a path to extinction.
Charles Darwin once remarked, “It is hardly an exaggeration to say that nature tells us, in the most emphatic manner, that she abhors perpetual self-fertilization.” And yet, Kobe University botanist Suetsugu Kenji knows of a few islands in Japan where orchids reproduce without ever opening their flowers.
He says, “I’ve long been captivated by Darwin’s skepticism about plants that rely entirely on self-pollination. When I found those non-blooming orchids, I felt this was a perfect chance to directly revisit this issue. The apparent defiance of evolutionary common sense made me wonder what precise conditions—both environmental and genetic—would allow a purely self-pollinating lifestyle to emerge, let alone persist.”
On this mind-bending episode of Impact Theory, Tom Bilyeu sits down with Ben Lamm, the visionary entrepreneur behind Colossal Biosciences, to explore a world that sounds straight out of science fiction—yet is rapidly becoming our reality. Together, they pull back the curtain on the groundbreaking technology making de-extinction not only possible, but increasingly practical, from resurrecting woolly mammoths and dire wolves to saving endangered species and unraveling the secrets of longevity.
Ben explains how CRISPR gene editing has unlocked the power to make precise DNA changes—editing multiple genes simultaneously, synthesizing entirely new genetic blocks, and pushing the limits of what’s possible in biology and conservation. The conversation dives deep into the technical hurdles, ethical questions, and the unexpected magic of re-engineering life itself, whether it’s creating hairier, “woolly” mice or tackling the colossal challenge of artificial wombs and universal eggs.
But this episode goes way beyond Jurassic Park fantasies. Tom and Ben debate the future of human health, gene selection through IVF, the specter of eugenics, global competition in biotechnology, and how AI will soon supercharge the pace of biological engineering. They even touch on revolutionary solutions to our plastic crisis and what it means to inspire the next generation of scientists.
Get ready to have your mind expanded. This is not just a podcast about bringing back extinct creatures—it’s a deep dive into the next frontiers of life on Earth, the technologies changing everything, and the choices we’ll face as architects of our own biology. Let’s get legendary.
By popular request we’ve begun adding playlists of the show as Podcasts on Youtube Music, I’ll try to add a new one every 2–3 days till we have most of our inventory up there, but given today’s Episode is *Cities of the Future*, a collection of all of those seemed a good idea https://www.youtube.com/playlist?list=PLIIOUpOge0LuyCbYUhy-79RQKkOXonmx4 These are the (tentatively named) upcoming playlists/podcasts list I’ll be adding, in no particular order: Megastructures & Extreme Engineering The Fermi Paradox & Alien Civilizations Space Colonization & Habitats Post-Scarcity & Future Civilizations Transhumanism & Human Evolution Propulsion & Interstellar Travel Terraforming & Planetary Engineering Mind, Machines & Alien Intelligence Future Warfare & Defense Strange Worlds & Alien Life.
What happens when intelligence escapes the bounds of flesh and bone? In this episode, we explore post-biological civilizations—entities that may trade biology for digital minds, machine bodies, or stranger forms still—and ask what becomes of identity, purpose, and humanity when the body is no longer required.

A new study suggests that, in the case of global catastrophe, urban agriculture alone could sustain only about one fifth of the population of a temperate, median-sized city, but the whole city could be fed by also farming land within a short distance of the urban area.
Matt Boyd of Adapt Research Ltd, New Zealand, and Nick Wilson of the University of Otago, New Zealand, present these findings in PLOS One.
Abrupt global catastrophes—such as nuclear wars, extreme pandemics, or solar storms—could severely hamper global trade. Shortages of resources like liquid fuels could disrupt food production and transport, possibly leading to famine. Prior research has suggested that this impact could be mitigated by urban agriculture, which includes such approaches as home, community, and rooftop gardens.
Recent Extinction Rebellion protests saw key sites across London shut down in an attempt to force the government to declare an ‘eco-emergency.’
Our dissatisfaction with breakdown on a global, individual and societal level pushes many of us into activism. Increased numbers of people report suffering from ‘eco-anxiety’, and a recent study showed only 29% of American millennials currently believe that the country is heading in the right direction.
But can decay be completely reversed by human effort?
In this podcast, Tom Cozens speaks with Dr Mark Hocknull, who points out that decay finds its cause in deeper laws governing the physical universe. According to the principle of entropy, breakdown and decay are inescapable aspects of the natural world. The second law of thermodynamics states that decay and disorder are inescapable, and will always increase over time, despite human effort to reverse the process.
In the face of a world inescapably programmed towards breakdown, should we fight back or give up?
In this episode, we return to the subject of existential risks, but with a focus on what actions can be taken to eliminate or reduce these risks.
Our guest is James Norris, who describes himself on his website as an existential safety advocate. The website lists four primary organizations which he leads: the International AI Governance Alliance, Upgradable, the Center for Existential Safety, and Survival Sanctuaries.
Previously, one of James’ many successful initiatives was Effective Altruism Global, the international conference series for effective altruists. He also spent some time as the organizer of a kind of sibling organization to London Futurists, namely Bay Area Futurists. He graduated from the University of Texas at Austin with a triple major in psychology, sociology, and philosophy, as well as with minors in too many subjects to mention.
Comets that have hit Earth have been a mixed bag. Early in Earth’s history, during the solar system’s chaotic beginning, they were likely the source of our planet’s water, ultimately making up about 0.02% of the planet’s mass. (Mars and Venus received a similar fraction.)
Comets brought complex organic molecules and the biosphere, but later posed a threat to the same in cometary collisions. A comet (or asteroid) likely caused the Tunguska Event in 1908 in Russia, and a comet fragment likely triggered the rapid climate shift of the Younger Dryas 12,800 years ago, with its widespread extinctions.
If such collisions happen here, they likely take place in other solar systems as well. Now three scientists in the United Kingdom have modeled the impacts of an icy cometary collision with an Earth-like, tidally locked terrestrial planet. Such objects are prime candidates in the search for habitable exoplanets outside our solar system.
