Is AI the Great Filter?

Artificial intelligence may be civilization’s greatest tool… or its last. Could AI explain why the galaxy seems silent, or does it make the Fermi Paradox even harder?

Fear-learning circuit shows how stress disrupts brain’s ability to suppress trauma

Fear is often thought of as a negative emotion but is actually a natural protective response to perceived threats or danger. It helps us survive. When we experience a situation that causes fear, it becomes stored in our brain as a fear memory. These fear memories prevent us from touching a hot stove after being burned or from stepping onto a busy street.

What about fear memories that take over? Post-traumatic stress disorder, or PTSD, is caused by severe acute or chronic stress that disrupts the learning process designed to suppress fear memories. These memories then begin to negatively affect a person’s quality of life.

Typically, our fear memories can be suppressed through extinction learning. The original memory or fear isn’t forgotten, but a new memory is formed and suppresses the original fear memory. However, extinction learning can become tricky in situations that involve traumatic memories.

The Zoo Hypothesis and the Fermi Paradox… Are We Being Watched?

Are aliens watching us? The Zoo Hypothesis suggests advanced civilizations may be hiding, enforcing a galactic quarantine, or masking reality itself. Explore the Fermi Paradox, Dyson dilemma, and the unsettling possibility we are not alone—but observed.

New effort will get genome sequences for entire Endangered Species list

The US Endangered Species Act compels the government to identify species at risk of extinction and devise plans to restore populations and the habitats they depend on. It has seen some spectacular successes, such as the restoration of the bald eagle to much of its original range. But over 2,300 plant and animal populations remain on the list, requiring ongoing government intervention.

On Thursday, it was announced that all of those species would see their genomes sequenced and tissue samples preserved to aid future conservation efforts. The work will be done by a partnership between two unexpected parties. One is the US government, which has generally attempted to undercut the Endangered Species Act as part of its anti-regulatory efforts. It is joined by Colossal Biosciences, a biotech company that has a controversial take on what actually constitutes a species.

Colossal has always said it had a conservation focus, but its headline-grabbing efforts have been directed toward restoring species that have been driven to extinction. It intends to do that by developing a combination of gene editing and reproductive technologies that it expects it can profitably license. But its dire wolf announcement, in which only a tiny handful of genetic changes were edited in to grey wolves, have raised some questions about its seriousness regarding these efforts.

Scientists open a million-year-old time capsule hidden beneath New Zealand

A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō. The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long before humans arrived.

Young disk around WRAY 15–1880 may contain a primitive planetary system

Italian astronomers have used the Very Large Telescope (VLT) to perform polarimetric observations of the star WRAY 15–1880 and its young circumstellar disk. Results of the new observations, presented June 10 on the arXiv preprint server, suggest that this disk may host a primitive planetary system.

Circumstellar disks are accretion disks orbiting stars, composed of gas, dust, planetesimals, asteroids or collision fragments. Around the youngest stars, they are the reservoirs of material out of which planets may form.

At a distance of some 492 light-years from Earth, WRAY 15–1880 (also known as RX J1842.9–3532) is a solar-type classical T Tau star in the CrA-North subregion of the Corona Australis (CrA) complex. It has a mass of around 1.24 solar masses and is estimated to be 2.8 million years old.
