Researchers observe stationary Hawking radiation in an analog black hole
Black holes are regions in space where gravity is very strong—so strong that nothing that enters them can escape, including light. Theoretical predictions suggest that there is a radius surrounding black holes known as the event horizon. Once something passes the event horizon, it can no longer escape a black hole, as gravity becomes stronger as it approaches its center.

Climate change and suppression tactics are critical factors increasing fires
Both climate change and forest management have been blamed for wildfire hazards increasing across western North America, but the relative influence of these drivers is still heavily debated. The results of a recent study show that in some ecosystems, human-caused climate change is the predominant factor; in other places, the trend can also be attributed to a century of fire suppression that has pr

Direct cloning method CAPTUREs novel microbial natural products
Microorganisms possess natural product biosynthetic gene clusters (BGCs) that may harbor unique bioactivities for use in drug development and agricultural applications. However, many uncharacterized microbial BGCs remain inaccessible. Researchers previously demonstrated a technique using transcription factor decoys to activate large, silent BGCs in bacteria to aid in natural product discovery.

The distribution of vertebrate animals redefines temperate and cold climate regions
The distribution of vegetation is routinely used to classify climate regions worldwide, yet whether these regions are relevant to other organisms is unknown. Researchers have established climate regions based on vertebrate species' distributions in a new study. They found that while high-energy climate regions are similar across vertebrate and plant groups, there are large differences in temperate

We could find extraterrestrial civilizations by their air pollution
Upcoming telescopes will give us more power to search for biosignatures on all the exoplanets we've found.

But what if we want to search for technological civilizations that might be out there? Could we find them by searching for their air pollution?
