Mycelial fibers, the fibrous cells found in fruiting mushroom bodies, have gained momentum as a sustainable material for making faux-leather and packaging owing to their excellent formability. Recently, a team of researchers has found a simple way of obtaining mycelial fibers, called 'mycelial pulp,' from fruiting mushroom bodies and bleaching them using sunlight while keeping their mycelial structures intact.

With a split-second muscle contraction, the greater blue-ringed octopus can change the size and color of the namesake patterns on its skin for purposes of deception, camouflage and signaling. Researchers have drawn inspiration from this natural wonder to develop a technological platform with similar capabilities for use in a variety of fields, including the military, medicine, robotics and sustainable energy.

Engineers have succeeded in implementing a stretchable organic solar cell by applying a newly developed polymer material that demonstrated the world's highest photovoltaic conversion efficiency (19%) while functioning even when stretched for more than 40% of its original state. This new conductive polymer has high photovoltaic properties that can be stretched like rubber. The newly developed polymer is expected to play a role as a power source for next-generation wearable electronic devices.

Coal is an abundant resource in the United States that has, unfortunately, contributed to climate change through its use as a fossil fuel. As the country transitions to other means of energy production, it will be important to consider and reevaluate coal's economic role. Coal may actually play a vital role in next-generation electronic devices.

Aptamers, nucleic acids capable of selectively binding to viruses, proteins, ions, small molecules, and various other targets, are garnering attention in drug development as potential antibody substitutes for their thermal and chemical stability as well as ability to inhibit specific enzymes or target proteins through three-dimensional binding. They also hold promise for swift diagnoses of colon cancer and other challenging diseases by targeting elusive biomarkers. Despite their utility, these aptamers are susceptible to easy degradation by multiple enzymes, presenting a significant challenge.

While fog presents a major hazard to transportation safety, meteorologists have yet to figure out how to forecast it with the precision they have achieved for precipitation, wind and other stormy events. This is because the physical processes resulting in fog formation are extremely complex, Now researchers report their findings from an intensive study centered on a northern Utah basin and conceived to investigate the life cycle of cold fog in mountain valleys.

Researchers have discovered that molecules experience non-reciprocal interactions without external forces. Fundamental forces such as gravity and electromagnetism are reciprocal, where two objects are attracted to each other or are repelled by each other. In our everyday experience, however, interactions don t seem to follow this reciprocal law.

Lights could soon use the full color suite of perfectly efficient organic light-emitting diodes, or OLEDs, that last tens of thousands of hours. The new phosphorescent OLEDs, commonly referred to as PHOLEDs, can maintain 90% of the blue light intensity for 10-14 times longer than other designs that emit similar deep blue colors. That kind of lifespan could finally make blue PHOLEDs hardy enough to be commercially viable in lights that meet the Department of Energy's 50,000-hour lifetime target. Without a stable blue PHOLED, OLED lights need to use less-efficient technology to create white light.

During X-ray diffraction experiments, bright lasers shine on a sample, producing diffracted images that contain important information about the material's structure and properties. But conventional methods of analyzing these images can be contentious, time-consuming, and often ineffective, so scientists are developing deep learning models to better leverage the data.
