Published Breakthrough synthesis method improves solar cell stability
(via sciencedaily.com)
Original source 
A new process yields 2D halide perovskite crystal layers of ideal thickness and purity through dynamic control of the crystallization process -- a key step toward ensuring device stability for optoelectronics and photovoltaics.
Published Mammalian cells may consume bacteria-killing viruses to promote cellular health
(via sciencedaily.com)
Original source 
Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell. A study suggests that mammalian cells internalize phages as a resource to promote cellular growth and survival.
Published New research finds stress and strain changes metal electronic structure
(via sciencedaily.com)
Original source 
New research shows that the electronic structure of metals can strongly affect their mechanical properties.
Published A superatomic semiconductor sets a speed record
(via sciencedaily.com)
Original source 
The search is on for better semiconductors. A team of chemists describes the fastest and most efficient semiconductor yet: a superatomic material called Re6Se8Cl2.
Published Conduction electrons drive giant, nonlinear elastic response in Sr2RuO4
(via sciencedaily.com)
Original source 
The hardness of a material normally is set by the strength of chemical bonds between electrons of neighboring atoms, not by freely flowing conduction electrons. Now a team of scientists has shown that current-carrying electrons can make the lattice much softer than usual in the material Sr2RuO4.
Published Cutting-edge imaging sheds new light on cells that break down bone
(via sciencedaily.com)
Original source 
Imaging technology shows that bone-resorbing osteoclasts gather in distinct pockets, leading to new insights for osteoporosis and cancer treatment.
Published Discovery of three novel minorisa species, the smallest predatory marine picoplankton
(via sciencedaily.com)
Original source 
Researchers have made a significant discovery by identifying and characterizing three novel species within the Minorisa genus of marine picoplankton. Before this study, only one species of Minorisa was recognized. This finding reveals previously unseen diversity of Minorisa, thereby enhancing species identification and our understanding of its ecological functions in marine ecosystems.
Published Even treated wood prevents bacterial transmission by hand
(via sciencedaily.com)
Original source 
According to a new study, surface treatment and moisture affect the antibacterial properties of wood. Based on the findings, treated wood should be increasingly used as surface material.
Published Membrane transporter ensures mobility of sperm cells
(via sciencedaily.com)
Original source 
Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such a transporter and its mechanism. These findings will enable a better understanding of the molecular foundations of reproductive capacity and could, in the long term, contribute to developing new approaches to treating fertility disorders and new methods of specific contraception.
Published Fungi used in food production could lead to new probiotics
(via sciencedaily.com)
Original source 
According to a new study, 2 fungi used to produce food products have potential probiotic effects on gut inflammation.
Published A potentially cheaper and 'cooler' way for hydrogen transport
(via sciencedaily.com)
Original source 
Researchers have developed a new hydrogen energy carrier material capable storing hydrogen energy efficiently and potentially more cheaply. Each molecule can store one electron from hydrogen at room temperature, store it for up the three months, and can be its own catalyst to extract said electron. Moreover, as the compound is made primarily of nickel, its cost is relatively low.
Published To navigate the world, we all shimmy like these electric fish
(via sciencedaily.com)
Original source 
An electric knifefish shimmies in the water for the same reason a dog sniffs or a human glances around a new place -- to make sense of their surroundings. For the first time, scientists demonstrate that a wide range of organisms, even microbes, perform the same pattern of movements in order to sense the world.
Published Analysis finds diversity on the smallest scales in sulfur-cycling salt marsh microbes
(via sciencedaily.com)
Original source 
Scientists have discovered that even among the sulfur-cycling microbes that are responsible for the 'rotten egg gas' smell in salt marsh air, diversity extends all the way to genomes and even to individual nucleotides.
Published Algae's surprising potential to help ease climate change worries
(via sciencedaily.com)
Original source 
The key to bringing global net-zero goals into reach may be algae, say researchers. Studies show impressive success of certain microalgae varieties to remove CO2 from the atmosphere then break it down into useful materials.
Published Zika infection in pregnant macaques slows fetal growth
(via sciencedaily.com)
Original source 
Zika virus infection in pregnant rhesus macaques slows fetal growth and affects how infants and mothers interact in the first month of life, according to a new study. The work has implications for both humans exposed to Zika virus and for other viruses that can cross the placenta, including SARS-CoV2, responsible for the COVID-19 pandemic.
Published Achieving large and uniform particle sizes
(via sciencedaily.com)
Original source 
Dispersions of polymer particles in a liquid phase (latexes) have many important applications in coatings technology, medical imaging, and cell biology. A team of researchers has now developed a method to produce stable polystyrene dispersions with unprecedentedly large, and uniform, particle sizes. Narrow size distributions are essential in many advanced technologies, but were previously difficult to produce photochemically.
Published Diapers can be recycled 200 times faster with light
(via sciencedaily.com)
Original source 
More than 100,000 tons of diapers are disposed of annually in Germany. Vast amounts of valuable resources, such as diaper liners, end up in the trash. The liners consist of special polymers, so-called superabsorbers. Researchers have now succeeded in considerably improving their complex recycling process. They use UV radiation to degrade the chemical chains that keep the polymers together. No chemicals are needed. Recycling at room temperature is 200 times faster than conventional recycling. The recycled polymers can then be processed to new adhesives and dyes.
Published Bizarre new fossils shed light on ancient plankton
(via sciencedaily.com)
Original source 
Recently discovered microfossils date back half a billion years. Resembling modern-day algae, they provide insight into early life in our oceans.
Published Sunflower extract fights fungi to keep blueberries fresh
(via sciencedaily.com)
Original source 
Opening a clamshell of berries and seeing them coated in fuzzy mold is a downer. And it's no small problem. Gray mold and other fungi, which cause fruit to rot, lead to significant economic losses and food waste. Now, researchers report that compounds from sunflower crop waste prevented rotting in blueberries. They suggest the food industry could use these natural compounds to protect against post-harvest diseases.
