Published Quantum sensor for the atomic world
(via sciencedaily.com)
Original source 
In a scientific breakthrough, an international research team has developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.
Published Nonreciprocal interactions go nonlinear
(via sciencedaily.com)
Original source 
Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.
Published Researchers explore the interplay between high-affinity DNA and carbon nanotubes
(via sciencedaily.com)
Original source 
Single-walled carbon nanotubes (SWCNTs) hold promise for biomedicine and nanoelectronics, yet the functionalization with single-stranded DNA (ssDNA) remains a challenge. Researchers using high-affinity ssDNA sequences identified through high-throughput selection. They demonstrated the effectivity and stability of these constructs using molecular dynamics simulations. Machine-learning models were used to accurately predict patterns that govern ssDNA-SWCNT binding affinity. These findings provide valuable insights into the interactions between ssDNA and SWCNTs.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine
(via sciencedaily.com)
Original source 
Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published It's got praying mantis eyes
(via sciencedaily.com)
Original source 
The praying mantis is one of the few insects with compound eyes and the ability to perceive 3D space. Engineers are replicating their visual systems to make machines see better.
Published Nanoscale device simultaneously steers and shifts frequency of optical light, pointing the way to future wireless communication channels
(via sciencedaily.com)
Original source 
A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space.
Published Traffic-related ultrafine particles hinder mitochondrial functions in olfactory mucosa
(via sciencedaily.com)
Original source 
Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder the function of mitochondria in human olfactory mucosa cells, a new study shows. The study showed that traffic-related UFPs impair mitochondrial functions in primary human olfactory mucosa cells by hampering oxidative phosphorylation and redox balance.
Published A new way to make element 116 opens the door to heavier atoms
(via sciencedaily.com)
Original source 
Researchers have successfully made super-heavy element 116 using a beam of titanium-50. That milestone sets the team up to attempt making the heaviest element yet: 120.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation
(via sciencedaily.com)
Original source 
Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
Published Nanoscopic imaging aids in understanding protein, tissue preservation in ancient bones
(via sciencedaily.com)
Original source 
A pilot study shows that nanoscopic 3-D imaging of ancient bone not only provides further insight into the changes soft tissues undergo during fossilization, it also has potential as a fast, practical way to determine which specimens are likely candidates for ancient DNA and protein sequence preservation.
Published Pioneering the cellular frontier
(via sciencedaily.com)
Original source 
Scientists use a multimodal approach that combines hard X-ray computed tomography and X-ray fluorescence imaging to see the structure and chemical processes inside of a single cell.
Published Converting captured carbon to fuel: Study assesses what's practical and what's not
(via sciencedaily.com)
Original source 
A new analysis sheds light on major shortfalls of a recently proposed approach to capture CO2 from air and directly convert it to fuel using electricity. The authors also provide a new, more sustainable, alternative.
Published Organs on demand? Scientists print voxel building blocks
(via sciencedaily.com)
Original source 
Scientists are bioprinting 3D structures with a material that is a close match for human tissue, paving the way for true biomanufacturing.
Published Researchers clarify how soft materials fail under stress
(via sciencedaily.com)
Original source 
Understanding how soft materials fail under stress is critical for solving engineering challenges as disparate as pharmaceutical technology and landslide prevention. A new study linking a spectrum of soft material behaviors -- previously thought to be unrelated -- led researchers to identify a new parameter they call the brittility factor, which allows them to simplify soft material failure behavior. This will ultimately help engineers design better materials that meet future challenges.
Published Waste Styrofoam can now be converted into polymers for electronics
(via sciencedaily.com)
Original source 
A new study describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known as PEDOT:PSS. Researchers also noted that the upgraded plastic waste can be successfully incorporated into functional electronic devices, including silicon-based hybrid solar cells and organic electrochemical transistors.
Published Shining light on amyloid architecture
(via sciencedaily.com)
Original source 
Researchers use microscopy to chart amyloid beta's underlying structure and yield insight into neurodegenerative disease.
Published Chemists design novel method for generating sustainable fuel
(via sciencedaily.com)
Original source 
Chemists have been working to synthesize high-value materials from waste molecules for years.
Published Converting wastewater to fertilizer with fungal treatment
(via sciencedaily.com)
Original source 
Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temperature, high-pressure process. Two studies explore the use of a fungal treatment to convert the leftover wastewater into fertilizer for agricultural crops.
Published How pollution may remain in water after oil spill cleanups
(via sciencedaily.com)
Original source 
The way oil drops break up at the water's surface means some oil may not get cleaned up after a spill.
Published Solar farms with stormwater controls mitigate runoff, erosion, study finds
(via sciencedaily.com)
Original source 
As the number of major utility-scale ground solar panel installations grows, concerns about their impacts on natural hydrologic processes also have grown. However, a new study by Penn State researchers suggests that excess runoff or increased erosion can be easily mitigated -- if these 'solar farms' are properly built.
