Published New research shows that bacteria get 'hangry,' too
(via sciencedaily.com) Original source Researchers have discovered, using a recently developed technology, that genetically identical cells within a bacterial community have different functions, with some members behaving more docile and others producing the very toxins that make us feel ill.
Published Rising temperatures alter 'missing link' of microbial processes, putting northern peatlands at risk
(via sciencedaily.com) Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.
Published Wastewater more potent breeding ground for antibiotic resistance than previously known
(via sciencedaily.com) Wastewater is a more potent environment for antibiotic resistance to evolve than previously known. A study shows that wastewaters have unique characteristics, allowing resistance genes to start their journey from harmless bacteria to those that cause disease.
Published Engineered E. coli delivers therapeutic nanobodies to the gut
(via sciencedaily.com) Original source Researchers have succeeded in developing an E. coli-based 'smart microbe' that secretes therapeutic payloads, including antibodies, into the gut. The genetically modified beneficial strain of bacteria blocks intestinal inflammation in a preclinical model of inflammatory bowel disease and has the potential to treat intestinal-based diseases.
Published Scallop eyes as inspiration for new microscope objectives
(via sciencedaily.com) Original source Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand and the eyes of scallops on the other. The new objectives enable high-resolution imaging of tissues and organs in a much wider variety of immersion media than with conventional microscope lenses.
Published Form is (mal)function: Protein's shape lets bacteria disarm it
(via sciencedaily.com) Shigella bacteria can infect humans but not mice. A team can now explain why. Their findings may explain the multifariousness of a key weapon of our immune system.
Published Boosting the body's anti-viral immune response may eliminate aging cells
(via sciencedaily.com) Original source Aging cells express a protein that is produced by human cytomegalovirus and is targeted by certain immune cells in the body. Harnessing the immune response to this protein could have multiple health benefits during aging.
Published White-tailed deer blood kills bacteria that causes Lyme disease
(via sciencedaily.com) Original source As tick season kicks in across the country, scientists have completed research that offers a promising lead in the fight against Lyme disease.
Published How plants cope with the cold light of day -- and why it matters for future crops
(via sciencedaily.com) New research has discovered a cold 'coping' mechanism that is under the control of the plant biological clock and could offer solutions to breeding more resilience into crops less suited to cold climates.
Published New details of SARS-COV-2 structure
(via sciencedaily.com) Researchers used computational modeling to reveal finer details surrounding the outer shell of the COVID-19 virus. The work expands the scientific community's understanding of SARS-COV-2, and could lead to more refined antiviral therapies and better vaccines.
Published Scientists discover hidden crab diversity among coral reefs
(via sciencedaily.com) The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.
Published How the gut creates a cozy home for beneficial microbiome species
(via sciencedaily.com) Original source The digestive tract of fruit flies remodels itself to accommodate beneficial microbiome species and maintain long-term stability of the gut environment, according to new research.
Published Ancient giant amphibians swam like crocodiles 250 million years ago
(via sciencedaily.com) Ancient 2m-long amphibians swam like crocodiles long before true crocodiles existed, according to a new study.
Published Earth prefers to serve life in XXS and XXL sizes
(via sciencedaily.com) Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
Published Juvenile black rockfish affected by marine heat wave but not always for the worse, research shows
(via sciencedaily.com) Larvae produced by black rockfish, a linchpin of the West Coast commercial fishing industry for the past eight decades, fared better during two recent years of unusually high ocean temperatures than had been feared, new research finds.
Published Detecting coral biodiversity in seawater samples
(via sciencedaily.com) Researchers have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from above a reef. The method has been confirmed to work through observations made by scientific divers in the same areas of ocean. This has paved the way for large-scale comprehensive surveys of reef-building coral to take place and removes the reliance of direct observations made through scientific scuba diving or snorkeling.
Published How whale shark rhodopsin evolved to see, in the deep blue sea
(via sciencedaily.com) A group of researchers discovered that the rhodopsin -- a protein in the eye that detects light -- of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions -- one of which is counterintuitively associated with congenital stationary night blindness in humans -- aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.
Published Is it COVID-19 or the flu? New sensor could tell you in 10 seconds
(via sciencedaily.com) Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu -- at much lower levels and much more quickly than conventional tests for either.
Published Conserving wildlife can help mitigate climate change
(via sciencedaily.com) Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.
Published Research into birds killed in window collisions reveals their microbiomes
(via sciencedaily.com) Researchers collected the bodies of birds that crashed into buildings while migrating, and used these specimens to learn about the relationship between birds and the microbes living in their guts -- which appears to be wildly different from mammals and their microbiomes.
