Astronomers probe layer-cake structure of brown dwarf’s atmosphere

Posted: 30 Jul 2021 01:54 PM PDT

Astronomers have developed a new way to capture all the exquisite 'layer-cake' details of a brown dwarf's cloud structure. Because brown dwarfs are similar to super-Jupiters, this innovative technique can help deepen scientists' understanding of the atmospheres of giant alien worlds that are more massive than Jupiter.

'Greening' biomaterials and scaffolds used in regenerative medicine

Posted: 30 Jul 2021 01:54 PM PDT

In the biomaterials industry, electrospinning is a ubiquitous fabrication method used to produce nano- to microscale fibrous meshes that closely resemble native tissue architecture. Alas, the process has traditionally used solvents that not only are environmentally hazardous but also a significant barrier to industrial scale-up, clinical translation, and widespread use. But now, researchers report that they have developed a 'green electrospinning' process that addresses those challenges, from managing environmental risks of volatile solvent storage and disposal at large volumes to meeting health and safety standards during both fabrication and implementation.

Ultrafast X-ray provides new look at plasma discharge breakdown in water

Posted: 30 Jul 2021 11:20 AM PDT

Occurring faster than the speed of sound, the mystery behind the breakdown of plasma discharges in water is one step closer to being understood as researchers pursue applying new diagnostic processes using state-of-the-art X-ray imaging to the challenging subject.

New research infuses equity principles into the algorithm development process

Posted: 30 Jul 2021 07:43 AM PDT

Researchers have found a new approach to incorporating the larger web of relevant data for predictive modeling for individual and community health outcomes.

Solar-powered microbes to feed the world?

Posted: 30 Jul 2021 07:43 AM PDT

An international research team has shown that using solar-panels to produce microbial protein -- which is rich not just in proteins but also in other nutrients -- is more sustainable, efficient and environmentally friendly than growing conventional crops. This method uses solar energy, land, nutrients, and carbon dioxide from the air.

Engineers bend light to enhance wavelength conversion

Posted: 30 Jul 2021 07:42 AM PDT

Engineers have developed a more efficient way of converting light from one wavelength to another, opening the door for improvements in the performance of imaging, sensing and communication systems.

Researchers film human viruses in liquid droplets at near-atomic detail

Posted: 29 Jul 2021 03:36 PM PDT

Researchers have used advanced electron microscopy (EM) technology to see how human viruses move in high resolution in a near-native environment. The visualization technique could lead to improved understanding of how vaccine candidates and treatments behave and function as they interact with target cells.

Ultra high performance flexible ultraviolet sensors for use in wearables

Posted: 29 Jul 2021 03:36 PM PDT

To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists have created a new type of light sensor that is both flexible and highly sensitive.

Artificial Intelligence learns better when distracted

Posted: 29 Jul 2021 03:36 PM PDT

Computer scientists from the Netherlands and Spain have determined how a deep learning system well suited for image recognition learns to recognize its surroundings. They were able to simplify the learning process by forcing the system's focus toward secondary characteristics.

New information storage and processing device

Posted: 29 Jul 2021 03:35 PM PDT

A team of scientists has developed a means to create a new type of memory, marking a notable breakthrough in the increasingly sophisticated field of artificial intelligence.

HR 8799 super-Jupiters’ days measured for the first time, gives a new spin on unraveling planet formation mystery

Posted: 29 Jul 2021 03:35 PM PDT

Astronomers have captured the first-ever spin measurements of HR 8799, the famed system that made history as the very first exoplanetary system to have its image taken.

Tiny wireless device illuminates neuron activity in the brain

Posted: 29 Jul 2021 03:35 PM PDT

A team lights a path forward for improved treatment of conditions including addiction and epilepsy and chronic pain. In a new article, they report on a wireless transcranial optogenetic simulation device that can send light through the skull rather than physically penetrating the blood-brain barrier.

'Green' synthesis of plastics from CO2

Posted: 29 Jul 2021 11:34 AM PDT

Using a CeO2 catalyst, researchers develop an effective catalytic process for the direct synthesis of polycarbonate diols without the need for dehydrating agents. The high yield, high selective process has CO2 blown at atmospheric pressure to evaporate excess water by-product allowing for a catalytic process that can be used with any substrate with a boiling point higher than water.

Systems intelligent organizations succeed – regardless of structures

Posted: 29 Jul 2021 09:22 AM PDT

Matrix, process, or something else? The structure of an organization is of little significance for its success, as long as there is systems intelligence, according to a new study.

Dark mode may not save your phone's battery life as much as you think, but there are a few silver linings

Posted: 29 Jul 2021 09:21 AM PDT

Dark mode is unlikely to make a big difference to battery life with the way that most people use their phones on a daily basis, says a new study. That doesn't mean that dark mode can't be helpful, though.

Through the thin-film glass, researchers spot a new liquid phase

Posted: 26 Jul 2021 12:29 PM PDT

A new study describes a new liquid phase in thin films of a glass-forming molecules. These results demonstrate how these glasses and other similar materials can be fabricated to be denser and more stable, providing a framework for developing new applications and devices through better design.
