The Science Behind Cancer's Size Connection Defies Decades-Old Belief
Larger animals face higher cancer risks due to increased cell division and oxidative stress, but those that reach large sizes rapidly evolve mechanisms to mitigate these effects, such as lower mutation rates or enhanced DNA repair mechanisms. The common dolphin, for example, evolved its large body size more quickly than other mammals, resulting in reduced cancer prevalence. This finding refines Cope's rule, which states that species with larger body sizes tend to have higher cancer risks.
The evolutionary trade-off between rapid growth and cancer resistance may be a key factor in understanding why some species are more resilient to cancer than others.
Can studying the unique biology of small, long-lived species like turtles or tortoises provide insights into cancer prevention and treatment that could inform human medicine?
Recent research indicates that the ancient megalodon likely had a body shape more akin to that of a lemon shark rather than the stocky form of a great white shark, as previously thought. This conclusion is supported by an analysis of fossilized vertebrae, which suggests a slender build that would have been more efficient for swimming and hunting. The study also posits that baby megalodons were comparable in size to great white sharks and capable of predation from a young age.
This research not only reshapes our understanding of megalodon’s biology but also highlights how evolutionary adaptations can influence the physical characteristics and behaviors of massive marine predators.
What implications could this new understanding of megalodon's anatomy have on our perceptions of ancient marine ecosystems and predator-prey dynamics?
The creation of wooly mice with long fur through simultaneous gene editing marks a significant milestone in the quest to bring back the woolly mammoth.

Colossal CEO Ben Lamm emphasized the need for humanity to invest in de-extinction technologies, citing the failure of modern conservation efforts and the potential benefits of bringing back extinct species. The company aims to use genetic editing techniques to revive the wooly mammoth, dodo bird, and Tasmanian tiger, among others. Lamm also expressed his optimism about the future, predicting significant advancements in synthetic biology and its applications.
As Colossal CEO Ben Lamm's vision for de-extinction takes shape, it raises intriguing questions about the ethics of playing God with nature – do we have a right to bring back species that were eradicated by our own actions?
The scale of Colossal's ambitions suggests that humanity's "moral obligation" to pursue de-extinction may be matched only by its potential for catastrophic consequences if not handled responsibly.
Shoppers are increasingly turning to smaller food brands, seeking more affordable and less processed options, which is threatening the growth of billion-dollar products from conglomerates such as Unilever. As a result, companies like Unilever and Procter & Gamble (P&G) are facing declining profits due to reduced sales volume. The shift in consumer behavior is driven by growing demand for healthier and more sustainable food options.
This phenomenon highlights the evolving nature of consumer preferences, where small-scale brands are often seen as more authentic and transparent, whereas large conglomerates may be perceived as out of touch with changing tastes.
Will this trend lead to a more decentralized food industry, with smaller players becoming increasingly influential in shaping consumer choices?
Colossal Biosciences is advancing its ambitious goal of resurrecting the woolly mammoth by 2028 through the genetic engineering of mice that exhibit mammoth-like fur traits.
