(via sciencedaily.com) Original source A collaborative team of experimental and computational physical chemists has made an important discovery in the field of electrochemistry, shedding light on the movement of water molecules near metal electrodes. This research holds profound implications for the advancement of next-generation batteries utilizing aqueous electrolytes.
Published Algae as a surprising meat alternative and source of environmentally friendly protein
(via sciencedaily.com) Original source A new study has demonstrate that the ingestion of two of the most commercially available algal species are rich in protein which supports muscle remodeling in young healthy adults. Their findings suggest that algae may be an interesting and sustainable alternative to animal-derived protein with respect to maintaining and building muscle.
Published Some coral species might be more resilient to climate change than previously thought
(via sciencedaily.com) Original source Some coral species can be resilient to marine heat waves by 'remembering' how they lived through previous ones, research suggests.
Published Hotter weather caused by climate change could mean more mosquitoesv
(via sciencedaily.com) Original source Research along James River in Richmond suggests that climate change could shorten window for predators to prey on larvae.
Published New method Ebola virus uses to infect cells
(via sciencedaily.com) Original source Scientists recently published findings indicating that Ebola virus creates and uses intercellular tunnels to move from cell to cell and evade treatments.
Published Genetic atlas detailing early stages of zebrafish development
(via sciencedaily.com) Original source Researchers have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the first five days of development, a period in which embryos mature from a single cell into distinct cell types.
Published Acid sensor and calcium store discovered in plants
(via sciencedaily.com) Original source Using optogenetics, researchers have detected a new acid sensor in plant cells that is addressing a cell-internal calcium store.
Published Ultrafast lasers map electrons 'going ballistic' in graphene, with implications for next-gen electronic devices
(via sciencedaily.com) Original source Research reveals the ballistic movement of electrons in graphene in real time. The observations could lead to breakthroughs in governing electrons in semiconductors, fundamental components in most information and energy technology.
Published Ancient DNA reveals how a chicken virus evolved to become more deadly
(via sciencedaily.com) Original source An international team of scientists led by geneticists and disease biologists has used ancient DNA to trace the evolution of Marek's Disease Virus (MDV). This global pathogen causes fatal infections in unvaccinated chickens and costs the poultry industry over $1 billion per year. The findings show how viruses evolve to become more virulent and could lead to the development of better ways to treat viral infections.
Published Diverse gut bacteria communities protect against harmful pathogens by nutrient blocking
(via sciencedaily.com) Original source New study demonstrates that diverse communities of resident bacteria can protect the human gut from disease-causing microorganisms. However, this protective effect is lost when only single species of gut bacteria are present. The researchers found that protective communities block the growth of harmful pathogens by consuming nutrients that the pathogen needs.
Published Opportunities to improve future HIV vaccine candidates
(via sciencedaily.com) Original source An effective HIV vaccine may need to prompt strong responses from immune cells called CD8+ T cells to protect people from acquiring HIV, according to a new study. The study findings draw comparisons between the immune system activity of past HIV vaccine study participants and people with HIV who naturally keep the virus from replicating even in the absence of antiretroviral therapy (ART). The latter individuals are often called 'long-term non-progressors' or 'elite controllers' (LTNPs/ECs).
Published Can you change a chicken into a frog, a fish or a chameleon?
(via sciencedaily.com) Original source Researchers have developed a theoretical framework that can reproduce and predict the patterns associated with gastrulation in a chicken embryo.
Published How the immune system fights to keep herpes at bay
(via sciencedaily.com) Original source In a study of lab-engineered cells, researchers identify how the immune system neutralizes the herpesvirus. The research maps, for the first time, the maneuvers used by virus and host in the cell nucleus, a poorly understood terrain of host-pathogen interaction. The findings could inform the design of new treatments for herpes and other viruses that replicate in the same way.
Published A promising pairing: Scientists demonstrate new combination of materials for quantum science
(via sciencedaily.com) Original source For the first time, scientists publish results on a new chip composed of diamond and lithium niobate. The results demonstrate the combination as a promising candidate for quantum devices.
Published New understanding of ancient genetic parasite may spur medical breakthroughs
(via sciencedaily.com) Original source Researchers have determined the structure of the most common material in our genomes. New treatments for autoimmune diseases, cancer and neurodegeneration may follow.
Published This next generation blue light could potentially promote or hinder sleep on command
(via sciencedaily.com) Original source Blue light from LED lamps and consumer electronics can mess with your sleep because it disrupts production of the natural sleep hormone melatonin. Tinted glasses or displays in night mode can mask, but don't remove, a portion of the disruptive wavelengths. But now, researchers report that they have designed more 'human-centric' LEDs that could potentially enhance drowsiness or alertness on command.
Published Gut bacteria of malnourished children benefit from key elements in therapeutic food
(via sciencedaily.com) Original source New research has identified key, naturally occurring biochemical components of a novel therapeutic food that is aimed at repairing malnourished children's underdeveloped gut microbiomes. The study also has identified the important bacterial strains that process these biochemical components. The findings may help guide treatment with a current food formulation and enable creation of new, more effective formulations in the future.
Published Enzymes can't tell artificial DNA from the real thing
(via sciencedaily.com) Original source Researchers have come one step closer to unlocking the potential of synthetic DNA, which could help scientists develop never-before-seen proteins in the lab.
Published Researchers create stable hybrid laser by 3D printing micro-optics onto fibers
(via sciencedaily.com) Original source For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and stable laser sources that would be useful in a variety of applications, including the lidar systems used for autonomous vehicles.
Published Nanoprobe with a barcode
(via sciencedaily.com) Original source Protein-splitting enzymes play an important role in many physiological processes. Such proteases are generally present in an inactive state, only becoming activated under certain conditions. Some are linked to diseases like infections or cancer, making it important to have methods that can selectively detect active proteases. Scientists have introduced a new class of protease-activity sensors: gold nanoparticles equipped with peptide DNA.
