Published Scientists transform algae into unique functional perovskites with tunable properties
(via sciencedaily.com) Scientists have transformed single-cell algae into functional perovskite materials. The team has converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by conventional synthetic production. The method can be applied to the mass production of perovskites with tunable structural and electro-optical properties from single-celled organisms.
Published Study shows how biodiversity of coral reefs around the world changes with depth
(via sciencedaily.com) Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.
Published A quick new way to screen virus proteins for antibiotic properties
(via sciencedaily.com) A whole new world of antibiotics is waiting inside the viruses that infect bacteria. Scientists are making it easier to study them.
Published Minke whales are as small as a lunge-feeding baleen whale can be
(via sciencedaily.com) A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.
Published Looking for risky viruses now to get ahead of future pandemics
(via sciencedaily.com) Rather than let the next outbreak take the world by surprise, two virologists say that the scientific community should invest in a four-part research framework to proactively identify animal viruses that might infect humans.
Published Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems
(via sciencedaily.com) An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.
Published Sea temperatures control the distributions of European marine fish
(via sciencedaily.com) An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.
Published Researchers uncover metabolic secrets of anaerobes and identify new strategies to treat c. difficile infections
(via sciencedaily.com) A team of investigators has identified metabolic strategies used by Clostridioides difficile to rapidly colonize the gut. The findings identify methods to better prevent and treat the most common cause of antibiotic-associated diarrhea and healthcare-acquired infections (HAIs). The team's approach has implications for understanding broader aspects of microbial metabolism, including responses to antibiotics, and production of important metabolites.
Published New insights into cellular 'bridges' shed light on development, disease
(via sciencedaily.com) Most cells in the bodies of living things duplicate their contents and physically separate into new cells through the process of cell division. But across many species, germ cells, those that become eggs or sperm, don't fully separate. They remain interconnected through small bridges called ring canals and cluster together. In a new study, researchers uncover how it is that germ cells in fruit flies form these ring canals, a finding that they say will provide new insights into a widely shared feature of development and into diseases in which cell division is disrupted.
Published New biosensor reveals activity of elusive metal that's essential for life
(via sciencedaily.com) A new biosensor offers scientists the first dynamic glimpses of manganese, an elusive metal ion that is essential for life.
Published Unprecedented increase in ocean plastic since 2005 revealed by four decades of global analysis
(via sciencedaily.com) A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a new study.
Published eDNA holds the key to safeguarding pollinators amid global declines
(via sciencedaily.com) Researchers have uncovered new evidence of western pygmy possums interacting with native flowers, providing an eDNA study to simultaneously detect mammal, insect and bird DNA on flowers.
Published Whether born naturally or via Cesarean section, babies receive essential microbes from their mothers
(via sciencedaily.com) Do cesarean-born babies miss out on essential microbes? New evidence suggests that the answer may be 'no.' Researchers report that mothers are able to transfer microbes to their babies via alternative, compensatory routes. While cesarean-born babies do receive less of their mother's gut microbiome during birth, they make up for this by drinking their mother's microbes in breastmilk.
Published Major North American oil source yields clues to one of earth's deadliest mass extinctions
(via sciencedaily.com) Geologists studying the Bakken Shale Formation discovered a critical kill mechanism behind a series of extinctions some 350 million years ago.
Published Paleontologists flip the script on anemone fossils
(via sciencedaily.com) Billions of sea anemones adorn the bottom of the Earth's oceans -- yet they are among the rarest of fossils because their squishy bodies lack easily fossilized hard parts. Now a team of paleontologists has discovered that countless sea anemone fossils have been hiding in plain sight for nearly 50 years. It turns out that fossils long-interpreted as jellyfish were anemones. To do so, a team of scientists has simply turned the ancient animals upside down.
Published Pattern recognition system that monitors disease-causing bacteria in C. elegans
(via sciencedaily.com) Original source Researchers describe a new manner of detecting microbial infection that intercepts pathogen-derived signals of growth to assess the relative threat of virulent bacteria. A nuclear hormone receptor in the nematode C. elegans senses a toxic metabolite produced by the bacterial pathogen Pseudomonas aeruginosa to activate innate immunity. These data reveal an ancient strategy that informs the origins of pathogen detection and may be among the most primordial forms of immune sensing in animals.
Published Does current shellfish anti-predator gear curb 'crunching' rays?
(via sciencedaily.com) It's not just humans who enjoy eating shellfish, so do marine rays. They like to 'crunch' on clams, which can sometimes take a big bite out of clammers' profits. Using aerial and underwater videos, researchers assessed the ability of the whitespotted eagle ray to interact with clams housed within a variety anti-predator materials. Whitespotted eagle rays have strong jaws, plate-like teeth and nimble pectoral fins, which make them formidable and highly maneuverable predators of clams.
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 Mineral particles and their role in oxygenating the Earth's atmosphere
(via sciencedaily.com) Mineral particles played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, according to new research.
