What’s new in science & tech? by David Brin

Okay, let’s turn to the side of civilization that is doing best. Doing spectacularly well in fact, despite a relentless campaign to undermine science. Just today—as I type this, in fact—I am in a conference call as a member of the advisory council of The Planetary Society, hearing reports about how TPS - under Bill Nye’s charismatic leadership - has seen a turnaround, with increasing membership and a social media following that has crested above a million! Why? Because people are noticing how many wondrous accomplishm...

Republican Congressmen Order DARPA to Halt Construction of Space Robot by B. J. Murphy

Believe it or not, President Donald Trump has repeatedly noted interest in space research and exploration. I don’t shy away from my various disagreements with the new President, but I’m also willing to admit that I particularly enjoy his pro-space venture policies. Which is why I find it a bit disconcerting to hear that Republican members of Congress are now ordering DARPA to end their work on Robotic Servicing of Geosynchronous Satellites.

Extended Space Travel Could Cause Irreversible Back Damage by George Dvorsky

New research shows that astronauts who return from extended missions in space experience a significant weakening of their spinal muscles. Disturbingly, their back muscles don’t return to normal even after several weeks back on Earth.

Alien Hunters Spot Freaky Radio Signal Coming From Nearby Star by George Dvorsky

Astronomers using the RATAN-600 radio telescope in the Russian Republic of Karachay-Cherkessia have detected an unusual signal emanating from a star located about 94 light-years from Earth. It’s not clear if the signal is being transmitted by aliens, but the researchers say we should keep a close watch on this intriguing new extraterrestrial candidate.

Want to Find Aliens? Look for Planets That Have Become Stars by George Dvorsky

Jupiter is often referred to as a “failed star,” leading some futurists to wonder if our descendants might set it ablaze in a process called planetary stellification. A new study suggests this is indeed theoretically possible—and that we should be on the hunt for galactic aliens who have already converted their gas giants into stellar objects.

Review of Phil Torres’ The End: What Science and Religion Tell Us About the Apocalypse by John G. Messerly

Phil Torres’ new book The End: What Science and Religion Tell Us about the Apocalypse, is one of the most important books recently published. It offers a fascinating study of the many real threats to our existence, provides multiple insights as to how we might avoid extinction, and it is carefully and conscientiously crafted.

Goodbye, Little Green Men by Susan Schneider They’re big-eyed and slight of build. They’re the grim, greenish beings that every moviegoer recognizes as aliens—the inscrutable inhabitants of a distant world. Playing supporting roles in countless films and TV shows, these hairless homunculi have become iconic.< But we've never seen a real alien. Indeed, we don't even know if real aliens exist. this essay was co-written with Seth Shostak

Introducing the Subfield of Agential Riskology by Phil Torres

The field of Existential Risk Studies has, to date, focused largely on risk scenarios involving natural phenomena, anthropogenic phenomena, and a specific type of anthropogenic phenomenon that one could term “technogenic.” The first category includes asteroid/comet impacts, supervolcanoes, and pandemics. The second encompasses climate change and biodiversity loss. And the third deals with risks that arise from the misuse and abuse of advanced technologies, such as nuclear weapons, biotechnology, synthetic biology, nanotechnology, and art...

A New Doomsday Argument by Phil Torres

I want to elaborate briefly on an issue that I mentioned in a previous article for the IEET, in which I argue (among other things) that we may be systematically underestimating the overall probability of annihilation. The line of reasoning goes as follows:

Top Three Strategies for Avoiding an Existential Risk by Phil Torres

Since the first species of Homo emerged in the grassy savanna of East Africa some 2 million years ago, humanity has been haunted by a small constellation of improbable existential risks from nature. We can call this our cosmic risk background. It includes threats posed by asteroid/comet impacts, super volcanic eruptions, global pandemics, solar flares, black hole explosions or mergers, supernovae, galactic center outbursts, and gamma-ray bursts. While modern technology could potentially protect us against some of the...
