Published Free-forming organelles help plants adapt to climate change
(via sciencedaily.com) Original source Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery. Researchers have now determined how these structures work on a molecular level, as well as where and how they form.
Published First effective treatment found for spitting cobra snakebite
(via sciencedaily.com) Original source Scientists have discovered a new snakebite treatment to prevent the devastating tissue damage caused by African spitting cobra venom. Spitting cobra venom is incredibly potent and causes dermonecrosis, which presents as rapid destruction of skin, muscle and bone around the site of the snakebite, and can lead to permanent injuries and disfigurements, including limb loss and amputations in extreme cases. Using the repurposed small molecule drug varespladib to block one of the two major dermonecrosis-causing toxins in spitting cobra venom prevents skin and muscle damage. Each year, it is estimated that snakebite causes long term detrimental effects in around 400,000 people across the world, with a substantial proportion of those in Africa the result of spitting cobra bites.
Published Researchers 'unzip' 2D materials with lasers
(via sciencedaily.com) Original source Researchers used commercially available tabletop lasers to create tiny, atomically sharp nanostructures in samples of a layered 2D material called hexagonal Boron Nitride (hBN). The new nanopatterning technique is a simple way to modify materials with light--and it doesn't involve an expensive and resource-intensive clean room.
Published Engineers develop innovative microbiome analysis software tools
(via sciencedaily.com) Original source Engineers have developed two new graph-based computational tools for tracking genomic variation within microbiomes.
Published The Clues for Cleaner Water
(via sciencedaily.com) Original source By using experimental electrochemical analyses, mass spectrometry, and computational quantum chemistry modeling, the researchers created an 'atomic-scale storyline' to explain how ozone is generated on NATO electrocatalysts. They identified that some of the nickel in NATO is probably leaching out of the electrodes via corrosion, and these nickel atoms, now floating in the solution near the catalyst, can promote chemical reactions that eventually generate ozone.
Published Using advanced genetic techniques, scientists create mice with traits of Tourette disorder
(via sciencedaily.com) Original source In research that may be a step forward toward finding personalized treatments for Tourette disorder, scientists have bred mice that exhibit some of the same behaviors and brain abnormalities seen in humans with the disorder.
Published Experiment opens door for millions of qubits on one chip
(via sciencedaily.com) Original source Researchers have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of these qubits on a single chip using mature manufacturing processes.
Published High-pressure spectroscopy: Why 3,000 bars are needed to take a comprehensive look at a protein
(via sciencedaily.com) Original source Why 3,000 bars are needed to take a comprehensive look at a protein: Researchers present a new high-pressure spectroscopy method to unravel the properties of proteins' native structures.
Published Improved nutrition, sanitation linked to beneficial changes in child stress and epigenetic programming
(via sciencedaily.com) Original source A new study provides some of the clearest and most comprehensive evidence to date on what is known about stress physiology and 'epigenetic programming.'
Published New quantum sensing scheme could lead to enhanced high-precision nanoscopic techniques
(via sciencedaily.com) Original source Researchers have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Published Aligned peptide 'noodles' could enable lab-grown biological tissues
(via sciencedaily.com) Original source Researchers have developed peptide-based hydrogels that mimic the aligned structure of muscle and nerve tissues, which could enable the development of functional lab-grown tissue.
Published When injecting pure spin into chiral materials, direction matters
(via sciencedaily.com) Original source The direction in which spin information is injected into chiral materials affects its ability to pass through them. These chiral 'gateways' could be used to design energy-efficient spintronic devices for data storage, communication and computing.
Published Genomes of 'star algae' shed light on origin of plants
(via sciencedaily.com) Original source Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.
Published Tweaking isotopes sheds light on promising approach to engineer semiconductors
(via sciencedaily.com) Original source Scientists have demonstrated that small changes in the isotopic content of thin semiconductor materials can influence their optical and electronic properties, possibly opening the way to new and advanced designs with the semiconductors.
Published How E. coli get the power to cause urinary tract infections
(via sciencedaily.com) Original source New research examines how the bacteria Escherichia coli, or E. coli -- responsible for most UTIs -- is able to use host nutrients to reproduce at an extraordinarily rapid pace during infection despite the near sterile environment of fresh urine.
Published Plants utilize drought stress hormone to block snacking spider mites
(via sciencedaily.com) Original source Recent findings that plants employ a drought-survival mechanism to also defend against nutrient-sucking pests could inform future crop breeding programs aimed at achieving better broadscale pest control.
Published Source of pregnancy complications from infections revealed by placenta map
(via sciencedaily.com) Original source The placenta's response to infections from malaria, toxoplasmosis and listeria has been mapped in high resolution, possibly paving the way for new treatment options.
Published New discovery of a mechanism that controls cell division
(via sciencedaily.com) Original source Researchers have discovered that how a special protein complex called the Mediator moves along genes in DNA may have an impact on how cells divide. The discovery may be important for future research into the treatment of certain diseases.
Published Novel chemical tool for understanding membrane remodeling in the cell
(via sciencedaily.com) Original source Researchers describe a natural product-like molecule, Tantalosin, that inhibits interaction between two proteins in complexes that reshape membranes inside the cell. The findings lead to a deeper understanding of how membrane remodeling works in human cells and future development of new drugs.
