Phys.org / Coffee as a staining agent substitute in electron microscopy
To ensure that the tissue structures of biological samples are easily recognizable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is uranyl acetate. However, some ...
Phys.org / Self-configuring optical devices automatically learn how to sort out light
Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different optical patterns at once is extremely complicated, and remains a major challenge in modern photonics.
Phys.org / The electrifying science behind Martian dust
Mars, often depicted as a barren red planet, is far from lifeless. With its thin atmosphere and dusty surface, it is an energetic and electrically charged environment where dust storms and dust devils continually reshape ...
Medical Xpress / Bright light suppresses eating and weight gain in mice
Past research has found that exposure to bright lights and high levels of noise can alter both physiological processes and human behavior. For instance, an elevated or limited exposure to bright lights and noise has been ...
Phys.org / Entanglement enhances the speed of quantum simulations, transforming long-standing obstacles into a powerful advantage
Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have made a significant discovery regarding quantum entanglement. This phenomenon, which has long been viewed as a significant obstacle in classical ...
Medical Xpress / Where are we at with the 'sunscreen wars'?
In Australia, we are exposed to some of the harshest and most dangerous levels of ultraviolet radiation (UV) in the world, so many of us know how important high SPF sunscreen is.
Phys.org / Some dogs can learn new words by eavesdropping on their owners
"Honey, will you take Luna to the P-A-R-K?" Both parents and dog owners know that some words should not be spoken, but only spelled, to prevent small ears from eavesdropping on the conversation. At the age of 1.5 years, toddlers ...
Phys.org / Deformable adjuvants can enhance immune activation in new vaccine design
Conventional vaccine adjuvants primarily rely on molecular binding and biochemical stimulation to activate immune responses, which often leads to limited efficacy in elderly or low-responsive populations. How to introduce ...
Phys.org / Sensor lights up to reveal scopolamine, a common substance used for sexual assault
A team from the Universitat Politècnica de València (UPV) has led the development of a new sensor capable of quickly and easily detecting scopolamine, one of the substances most commonly used in crimes of chemical submission, ...
Phys.org / Cells use Morse code-like rhythms to coordinate growth
Cells experience many different types of stress, such as starvation or stress caused by too much salt or too high a temperature. Insulin signals respond to such stress signals by sending the protein DAF-16 into the cell nucleus ...
Tech Xplore / New process densifies electrolytes, stabilizing lithium anodes for long-lasting all-solid-state batteries
Researchers at the Paul Scherrer Institute PSI have achieved a breakthrough on the path to practical application of lithium metal all-solid-state batteries—the next generation of batteries that can store more energy, are ...
Phys.org / How did these strange, ancient organisms turn into such remarkable fossils?
In Earth's fossil record, soft-bodied organisms like jellyfish rarely stand the test of time. What's more, it's hard for any animal to get preserved with exceptional detail in sandstones, which are made of large grains, are ...
