Large swings in past ocean oxygen revealed

As the climate warms, there is major concern that Earth’s ocean will lose oxygen. A study has revealed that locked in ancient deep-sea sediments is evidence for oxygen loss in the world’s ocean during past glacial periods, indicating that widespread ox…

The fuel economy of a microswimmer

The amount of power a microswimmer needs to move can now be determined more easily. Scientists developed a general theorem to calculate the minimal energy required for propulsion. These insights allow a profound understanding for practical applications…

Self-correcting quantum computers within reach?

Quantum computers promise to reach speeds and efficiencies impossible for even the fastest supercomputers of today. Yet the technology hasn’t seen much scale-up and commercialization largely due to its inability to self-correct. Quantum computers, unli…

Traumatic memories can rewire the brain

Researchers found that fear conditioning led to learning-specific changes in neuronal-network activity in the dorsal part of the medial prefrontal cortex of mice. This study demonstrates the use of combined methods for detailed visualization of the dyn…
