Scientists found that black holes across vastly different size ranges appear to launch powerful jets according to the same underlying rule. The finding may explain why some black holes erupt years after consuming a star and could help predict future outbursts.

Researchers found that atomic steps only one atom high can steer quantum vortices through superconductors, making their movement more than 1,000 times easier in one direction than another. The effect offers a way to control vortex motion at the scale relevant to superconducting devices.

Analysis of uranium cubes and wartime records indicates that Nazi Germany’s final reactor experiment was far from operational. The program lacked the large supplies of uranium and heavy water required to sustain a working reactor.

Scientists found that black holes across vastly different size ranges appear to launch powerful jets according to the same underlying rule. The finding may explain why some black holes erupt years after consuming a star and could help predict future outbursts.
The key shift is evidence that jet formation follows a common mechanism across black holes

A shared rule could turn black hole jets from isolated spectacles into predictable events governed by a common physical process.

Researchers found that atomic steps only one atom high can steer quantum vortices through superconductors, making their movement more than 1,000 times easier in one direction than another. The effect offers a way to control vortex motion at the scale relevant to superconducting devices.
The discovery turns a nanoscale surface defect into a functional guide for quantum motion rather

Analysis of uranium cubes and wartime records indicates that Nazi Germany’s final reactor experiment was far from operational. The program lacked the large supplies of uranium and heavy water required to sustain a working reactor.
The evidence weakens claims that Germany was close to producing a nuclear reactor or weapon

Archaeologists say they found jars from a shipwreck that could be as much as 4,700 years old. Outside experts remain skeptical, but the black residue inside the jars could help determine their age, origin, and connection to a wreck.
5:00 PMThe New York TimesNew research indicates that squid had spread across the world's oceans before the asteroid impact that ended the Cretaceous period. The finding extends evidence of their global distribution to before the Cretaceous-Paleogene mass extinction.

Researchers found that cortisol helps strengthen memories of emotional experiences by changing communication between brain networks involved in emotion and memory. The mechanism may explain why stressful moments can remain unusually vivid and persistent.

Scientists identified an enzyme that helps bacteria break down certain biodegradable plastics, while conventional plastic remained largely intact in soil. Several biodegradable materials decomposed completely within about a year under the tested conditions.

Satellite observations recorded large atmospheric waves in the upper atmosphere above Hurricane Simon as the storm generated powerful winds and flooding along Mexico’s coast. The images show how hurricanes can transmit energy far above the weather systems visible near the surface.

Archaeologists say they found jars from a shipwreck that could be as much as 4,700 years old. Outside experts remain skeptical, but the black residue inside the jars could help determine their age, origin, and connection to a wreck.
The claim is still provisional because the jars alone do not establish the age or

If confirmed, the find would push back the earliest known evidence of long-distance maritime trade and shipbuilding.
Summary
New research indicates that squid had spread across the world's oceans before the asteroid impact that ended the Cretaceous period. The finding extends evidence of their global distribution to before the Cretaceous-Paleogene mass extinction.
The key shift is temporal: squid were already a globally distributed group before the extinction,

It pushes back the timeline for squid's global expansion and sharpens the baseline for measuring how the mass extinction reshaped ocean life.

Researchers found that cortisol helps strengthen memories of emotional experiences by changing communication between brain networks involved in emotion and memory. The mechanism may explain why stressful moments can remain unusually vivid and persistent.
The finding links a stress hormone to a specific network-level process rather than treating stronger

Scientists identified an enzyme that helps bacteria break down certain biodegradable plastics, while conventional plastic remained largely intact in soil. Several biodegradable materials decomposed completely within about a year under the tested conditions.
The result points to a biological route for handling selected biodegradable plastics, not a solution

Enzyme-based recycling could reduce waste from biodegradable plastics, but it does not address the persistence of conventional plastics.
Summary
Satellite observations recorded large atmospheric waves in the upper atmosphere above Hurricane Simon as the storm generated powerful winds and flooding along Mexico’s coast. The images show how hurricanes can transmit energy far above the weather systems visible near the surface.
The observations connect intense tropical storms with disturbances in the upper atmosphere, where those waves
