We tend to think of Extraterrestrial Intelligences (ETIs)—if they exist—as civilizations that have overcome the problems that still plague us. They're advanced, peaceful, disease-free technological societies that enjoy absolute political stability as they accomplish feats of impeccable engineering. Can that really be true in a Universe where entropy sets the stage upon which events unfold?
Yes, we’ve all heard that three white dire wolves are running around at some secret location, and we’ve heard about Colossal Biosciences, a Dallas-based firm that, it says, is going to fix the “colossal problem” of extinction. The main way they propose to do it—and the bit that’s gained all the attention—is to “de-extinct” animals by finding fossil DNA of extinct species, sequencing some bits that presumptively code for a few of their traits, and then, using CRISPR, put those bits into the fertilized eggs of a living species that’s a close living relative. That way you get a hybrid animal, which is by necessity genetically about 99.9% or more of the living species but with a few traits of the extinct species. Then–voilà–you can say you have “de-extincted” the species. The misleading hype involved in that verb is obvious.
For example, dire wolf genes were extracted from fossil specimens, and 15 of those bits were edited into 14 genes in the fertilized egg of a grey wolf (they actually put in 20 bits, but 5 of those involved mutations existing in dogs and wolves. Since the grey wolf genome has 2.4 billion bases, you can see that only a tiny bit of dire wolf genome went into the wolf genome. The edited wolf egg was then transferred into surrogate dog mothers, and the mostly-grey-wolf hybrids were extracted by caesarian section (the dogs weren’t killed). Voilà: they got three largish white wolves that they called dire wolves. (The white color, by the way, did not come from the dire wolf DNA bnt from dog or coyote mutations. They edited whiteness into the hybrid because dire wolves were white when they featured, much larger, in the t.v. show Game of Thrones. We don’t know what color the dire wolves really were, but I doubt it was snow white. They did not live in snowy areas.)
The Big Project of Colossal, however, is the “de-extincting” of the woolly mammoth, a project I’ve discussed on this site before. (The dodo and thylacine are also on tap to be edited back to life.) Colossal promises that we’ll have faux mammoths—which paleobiologist and mammoth expert Tori Herridge denigrated as “elephants in a fur coat” because a few of the changes will involve hairiness—by 2028. Good luck with that!
There are many problems with the “de-extinction” scenarios that have nevertheless raked in $435 million for Colossal thanks to donors like Paris Hilton and Tiger Woods. And although other scientists like Tori and Adam Rutherford have described some of these problems, I decided to summarize them all in one place for American readers. Thus my op-ed in today’s Boston Globe, which you can find here, though it may be paywalled. Clicking on the headline below, however will take you to a non-paywalled archived version of the text.
The article summarizes four major problems with “de-extinction”, which you can read in the article. The Globe had a special piece of art made to illustrate my article, and I absolutely love it (see below, and notice the hook). The illustration is the creation of Patric Sandri, a Swiss artist. Thanks to the artist and especially to my editor, who was perhaps the most amiable and easiest op-ed editor I’ve ever worked with.
Enjoy (unless you work for Colossal)!

This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of scientists investigated ways to cut the travel time to the second most distant planet from the Sun. This study has the potential to help scientists, engineers, and mission planners develop low-cost and novel techniques for deep space travel while conducting cutting-edge science.
How can nanosatellites help advance lunar exploration and settlement? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers from Grahaa Space in India investigated the pros, cons, and applications for using nanosatellites on the Moon. This study has the potential to help scientists, engineers, mission planners, and future lunar astronauts develop and test new technologies for advancing lunar exploration, and possibly beyond the Moon.
What are the best methods to explore Valles Marineris on Mars, which is the largest canyon in the solar system? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers investigated how helicopters could be used to explore Valles Marineris, which could offer insights into Mars’ chaotic past. This study has the potential to help scientists and engineers develop new methods for studying Mars’s history and whether the Red Planet once had life as we know it.
Astronomers Observe Dark Matter Bridge in the Perseus Cluster
Space exploration not only allows us to look out into the universe but it also allows us to look back at Earth. ESA’s Biomass satellite will measure the amount of carbon in the world's forests, tracking how the carbon cycle absorbs and releases carbon over the seasonal cycles. It launched this week from the Kourou Spaceport in French Guiana atop a Vega-C rocket and safely reached its intended orbit. It has a synthetic aperture radar that can penetrate forest canopies like an infrared telescope can peer through dark dust clouds.
The James Webb Space Telescope has a number of science goals. One of them is to help understand the evolution of galaxies and their formation within the first billion years after the Big Bang. Astronomers have completed an initial Webb telescope survey that discovered 1,700 galaxy groups. Many of these groups date back to when the Universe was less than 1 billion years old. The survey spans 12 billion years of cosmic history, from these ancient formations to the present day.
Understanding how life started on Earth means understanding the evolution of chemistry in the Solar System. It began in the protoplanetary disk of debris around the Sun and reached a critical point when life appeared on Earth billions of years ago. Close to the Sun, the chain of chemical evidence is broken by the Sun's radiation. But further out in the Solar System, billions of kilometres away, some of that ancient chemistry is preserved.
