Published Phage structure captured, to benefit biotech applications
(via sciencedaily.com) Original source Researchers have mapped out what a commonly-used form of phage looks like, which will help design better uses in future.
Published Researcher uses mammal DNA to zoom into the human genome with unprecedented resolution
(via sciencedaily.com) Original source Scientists have precisely identified base pairs of the human genome that remained consistent over millions of years of mammalian evolution, and which play a crucial role in human disease. The team analyzed the genomes of 240 mammals, including humans and identified base pairs that were 'constrained' -- meaning they remained generally consistent -- across mammal species over the course of evolution. The most constrained base pairs in mammals were over seven times more likely to be causal for human disease and complex trait, and over 11 times more likely when researchers looked at the most constrained base pairs in primates alone.
Published A look inside stem cells helps create personalized regenerative medicine
(via sciencedaily.com) Original source Researchers have examined a specific type of stem cell with an intracellular toolkit to determine which cells are most likely to create effective cell therapies.
Published Brain-belly connection: Gut health may influence likelihood of developing Alzheimer's
(via sciencedaily.com) Original source A new study pinpoints 10 bacterial groups associated with Alzheimer's disease, provides new insights into the relationship between gut makeup and dementia.
Published Global warming puts whales in the Southern Ocean on a diet
(via sciencedaily.com) Original source In the autumn, when right whales swim towards the coasts of South Africa, they ought to be fat and stuffed full. But in recent years, they have become thinner because their food is disappearing with the melting sea ice.
Published Bacteria killing material could tackle hospital superbugs
(via sciencedaily.com) Original source Researchers have used a common disinfectant and antiseptic to create a new antimicrobial coating material that effectively kills bacteria and viruses, including MRSA and SARS-COV-2.
Published Bacteria: Radioactive elements replace essential rare earth metals
(via sciencedaily.com) Original source Bacteria can use certain radioactive elements to sustain their metabolism.
Published How bacteria evolve resistance to antibiotics
(via sciencedaily.com) Original source Bacteria can rapidly evolve resistance to antibiotics by adapting special pumps to flush them out of their cells, according to new research. Antimicrobial resistance is a growing problem of global significance. The rise of resistant 'superbugs' threatens our ability to use antimicrobials like antibiotics to treat and prevent the spread of infections caused by microorganisms. It is hoped that the findings will improve how antibiotics are used to help prevent further spread of antimicrobial resistance.
Published Hammerhead sharks hold their breath on deep water hunts to stay warm
(via sciencedaily.com) Original source Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.
Published Earth's first animals had particular taste in real estate
(via sciencedaily.com) Original source Even without body parts that allowed for movement, new research shows -- for the first time -- that some of Earth's earliest animals managed to be picky about where they lived.
Published Scientists create CRISPR-based drug candidate targeting the microbiome
(via sciencedaily.com) Original source A new drug candidate targeting E. coli in the gut is in phase 1 clinical trials. According to a new paper it may improve the well-being of blood cancer patients and reduce their mortality rate from E. coli infections.
Published 'Super-resolution' imaging technology
(via sciencedaily.com) Original source Researchers describe developing a super-resolution imaging platform technology to improve understanding of how nanoparticles interact within cells.
Published Scientists develop gene silencing DNA enzyme that can target a single molecule
(via sciencedaily.com) Original source Researchers have developed a DNA enzyme -- or DNAzyme -- that can distinguish between two RNA strands inside a cell and cut the disease-associated strand while leaving the healthy strand intact. This breakthrough 'gene silencing' technology could revolutionize the development of DNAzymes for treating cancer, infectious diseases and neurological disorders.
Published Researchers discover a cause of rapid ice melting in Greenland
(via sciencedaily.com) Original source While conducting a study of Petermann Glacier in northwest Greenland, researchers uncovered a previously unseen way in which the ice and ocean interact. The glaciologists said their findings could mean that the climate community has been vastly underestimating the magnitude of future sea level rise caused by polar ice deterioration.
Published Plastic can drift far away from its starting point as it sinks into the sea
(via sciencedaily.com) Original source Discarded or drifting in the ocean, plastic debris can accumulate on the water's surface, forming floating islands of garbage. Although it's harder to spot, researchers suspect a significant amount also sinks. In a new study in ACS' Environmental Science & Technology, one team used computer modeling to study how far bits of lightweight plastic travel when falling into the Mediterranean Sea. Their results suggest these particles can drift farther underwater than previously thought.
Published First observational evidence of beaufort gyre stabilization, which could be precursor to huge freshwater release
(via sciencedaily.com) Original source A new study provides the first observational evidence of the stabilization of the anti-cyclonic Beaufort Gyre, which is the dominant circulation of the Canada Basin and the largest freshwater reservoir in the Arctic Ocean.
Published T cells can activate themselves to fight tumors
(via sciencedaily.com) Original source Scientists find an auto-signaling mechanism driving the T cell anti-tumor response; findings may inspire new cancer therapeutics and biomarkers.
Published New probe aids novel findings on cell functions
(via sciencedaily.com) Original source New research shows the use of a new cellular probe helped discover new findings about certain cellular processes.
Published An unprecedented view of gene regulation
(via sciencedaily.com) Original source Using a new technique, researchers have shown that they can map interactions between gene promoters and enhancers with 100 times higher resolution than has previously been possible.
Published Tiny microbes could brew big benefits for green biomanufacturing
(via sciencedaily.com) Original source Scientists find new route in bacteria to decarbonize industry. The discovery could reduce greenhouse gas emissions from the manufacturing of fuels, drugs, and chemicals. A research team has engineered bacteria to produce new-to-nature carbon products that could provide a powerful route to sustainable biochemicals.
