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, such as targeted transport of molecules and substrates. Read more ›

To study muscle diseases, scientists rely on the mouse as a model organism. Researchers have now developed a new method that is not only faster and more efficient than conventional ones but also greatly reduces the number of experimental animals needed for studying the function of genes in muscle fibers.

Researchers have discovered a convenient new way to track levels of omega-3 fatty acids in the bloodstream, making it much easier to access information that is critical to cardiovascular and cognitive health, but which has previously been challenging to gather. While the human body can generate most of the fats it needs, it cannot produce adequate levels of omega-3 fatty acids and must obtain them from dietary sources. Read more ›

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 dynamics of neural networks, and describes techniques that could be used to uncover additional information about the neurological changes associated with learning and memory.  Read more ›

Researchers have long been exploring the effect of using tailored laser drives to manipulate the properties of quantum materials away from equilibrium. One of the most striking demonstrations of these physics has been in unconventional superconductors, where signatures of enhanced electronic coherences and super-transport have been documented in the resulting non-equilibrium states. However, these phenomena have not yet been systematically studied or optimized, primarily due to the complexity of the... Read more ›

Lithium–sulfur batteries (LSBs) offer a higher energy storage potential. However, issues like formation of lithium polysulfides and lithium dendrites lead to capacity loss and raise safety concerns. Now, researchers have developed a graphene separator embedded with platinum-doped gold nanoclusters, which enhance lithium-ion transport and facilitate redox reactions. This breakthrough addresses the long-standing issues associated with LSBs, setting the stage for their commercialization. Read more ›

Researchers have identified a new way of mapping ‘phosphenes’ – the visual perception of the bright flashes we see when no light is entering the eye – to improve the outcome of surgery for patients receiving a cortical visual prosthesis (‘bionic eye’). Read more ›

Researchers developed a nanostructured light diffuser that provides balanced lighting by diffracting blue and red light, and can be cleaned by simple rinsing with water. The diffuser consists of cheap materials and can be shaped with common tools. A protective glass coating maintains the diffuser's optical performance yet adds durability. This work might improve the visual performance of everyday lighting displays. Read more ›

One of the greatest strengths of NASA’s James Webb Space Telescope is its ability to give astronomers detailed views of areas where new stars are being born. The latest example, showcased here in a new image from Webb’s Mid-Infrared Instrument (MIRI), is NGC 346 – the brightest and largest star-forming region in the Small Magellanic Cloud. Read more ›

Among people who report memory and thinking problems, some show no signs of a problem on standard tests, while others have subtle declines on their tests. A new study shows that people who have subtle problems with these tests may have an increased risk of developing mild cognitive impairment, which can be a precursor to dementia. Read more ›

Sometimes it is worthwhile to look at the details, to study aspects that seem to be uninteresting or were previously ignored, and see noteworthy phenomena come to light. Researchers showed that male honey bees (drones), long considered lazy, are (at times) the most active members of the colony.  Read more ›

Lack of rainfall is not the only measure of drought. New research shows that despite a series of storms, the impact of drought can persist in streams and rivers for up to 3.5 years. Read more ›
