Published Electric vehicle batteries could get big boost with new polymer coating
(via sciencedaily.com) Scientists have developed a polymer coating that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles. The advance opens up a new approach to developing EV batteries that are more affordable and easy to manufacture.
Published Wheat's ancient roots of viral resistance uncovered
(via sciencedaily.com) The DNA sequence of a gene in wheat responsible for resisting a devastating virus has been discovered, providing vital clues for managing more resistant crops and maintaining a healthy food supply.
Published Phage attacks shown in new light
(via sciencedaily.com) New methodology and tools provide an opportunity to watch in unprecedented detail as a phage attacks a bacterium.
Published Controlling electric double layer dynamics for next generation all-solid-state batteries
(via sciencedaily.com) Development of all-solid-state batteries is crucial to achieve carbon neutrality. However, their high surface resistance causes these batteries to have low output, limiting their applications. To this end, researchers have employed a novel technique to investigate and modulate electric double layer dynamics at the solid/solid electrolyte interface. The researchers demonstrate unprecedented control of response speed by over two orders of magnitude, a major steppingstone towards realization of commercial all-solid-state batteries.
Published Rhythmic eating pattern preserves fruit fly muscle function under obese conditions
(via sciencedaily.com) Obese fruit flies are the experimental subjects in a study of the causes of muscle function decline due to obesity. In humans, skeletal muscle plays a crucial role in metabolism, and muscle dysfunction due to human obesity can lead to insulin resistance and reduced energy levels.
Published Biologists, chemical engineers collaborate to reveal complex cellular process inside petunias
(via sciencedaily.com) Once upon a time, prevailing scientific opinion might have pronounced recently published research as unneeded. Now, climate change implications have heightened the need for this line of research. Flowers emit scent chemicals called volatile organic compounds (VOCs). Earlier this year, a study identified a protein that plays a key role in helping petunias emit volatiles.
Published Extreme fast charging capability in lithium-ion batteries
(via sciencedaily.com) Lithium-ion batteries dominate among energy storage devices and are the battery of choice for the electric vehicle industry. Improving battery performance is a constant impetus to current research in this field. Towards this end, a group of researchers has synthesized a lithium borate-type aqueous polyelectrolyte binder for graphite anodes. Their new binder helped improve Li-ion diffusion and lower impedance compared to conventional batteries.
Published Fluorescent protein sheds light on bee brains
(via sciencedaily.com) An international team of bee researchers has integrated a calcium sensor into honey bees to enable the study of neural information processing including response to odors. This also provides insights into how social behavior is located in the brain.
Published 74,000 fruit fly brain images released
(via sciencedaily.com) Neuroscience research just got a little bit easier, thanks to the release of tens of thousands of images of fruit fly brain neurons.
Published Researchers bioengineer an endocrine pancreas for type 1 diabetes
(via sciencedaily.com) Scientists recently developed an efficient way to transplant pancreatic islets and demonstrated that the method can effectively reverse type 1 diabetes in nonhuman primates.
Published Pseudomonas aeruginosa Bacteria produce a molecule that paralyzes immune system cells
(via sciencedaily.com) Researchers have discovered a strong immunological effect of the molecule LecB -- and a way to prevent it.
Published New study unveils epigenetic 'traffic lights' controlling stop and go for gene activity
(via sciencedaily.com) A major new study reveals a 'traffic light' mechanism controlling genetic activity within cells -- a system which could potentially be targeted by cancer drugs already in development. The research describes how 'epigenetic' changes to the structure of DNA can act as a stop-go signal in determining whether a gene should be read. Unlike our genetic make-up, which is well understood, the world of epigenetics is still largely unexplored and referred to as the 'dark matter' of the genome.
Published Mapping unknown territory
(via sciencedaily.com) A detailed atlas of gene expression in the zebrafish brain.
Published Pink + pink = gold: hybrid hummingbird's feathers don't match its parents
(via sciencedaily.com) Scientists thought a gold-throated hummingbird was a new species. DNA revealed that it's a hybrid of two different species, each with pink throats. The discovery sheds light on how birds produce feather colors and how hummingbirds evolved their dazzling hues.
Published Your gut's microbiome, on a chip
(via sciencedaily.com) Researchers describe how gut-on-a-chip devices can bridge lab models and human biology. Modeling the microbiome is particularly difficult because of its unique environmental conditions, but through creative design, gut-on-a-chip devices can simulate many of these properties, such as the gut's anaerobic atmosphere, fluid flow, and pulses of contraction/relaxation. Growing intestinal cells in this environment means that they more closely resemble human biology compared to standard laboratory cell cultures.
Published Evolutionary history of detoxifying enzymes reconstructed
(via sciencedaily.com) Biochemists have succeeded in resurrecting the ancestral genes of five detoxifying enzymes which are present in all tetrapods to show how their divergence in function has occurred.
Published Ancient proteins offer new clues about origin of life on Earth
(via sciencedaily.com) Original source By simulating early Earth conditions in the lab, researchers have found that without specific amino acids, ancient proteins would not have known how to evolve into everything alive on the planet today -- including plants, animals, and humans.
Published Corralling ions improves viability of next generation solar cells
(via sciencedaily.com) Researchers have discovered that channeling ions into defined pathways in perovskite materials improves the stability and operational performance of perovskite solar cells. The finding paves the way for a new generation of lighter, more flexible, and more efficient solar cell technologies suitable for practical use.
Published Cells avoid multitasking
(via sciencedaily.com) Textbooks will tell you that in dividing cells, production of new DNA peaks during the S-phase, while production of other macromolecules, such as proteins, lipids, and polysaccharides, continues at more or less the same level. Molecular biologists have now discovered that this is not true: protein synthesis shows two peaks and lipid synthesis peaks once.
Published Successful cure of HIV infection after stem cell transplantation, study suggests
(via sciencedaily.com) Haematopoietic stem cell transplantation for the treatment of severe blood cancers is the only medical intervention that has cured two people living with HIV in the past. An international group of physicians and researchers has now identified another case in which HIV infection has been shown to be cured in the same way. The successful healing process of this third patient was for the first time characterized in great detail virologically and immunologically over a time span of ten years.
