Published Microbial viruses act as secret drivers of climate change
(via sciencedaily.com) Original source Scientists have discovered that viruses that infect microbes contribute to climate change by playing a key role in cycling methane, a potent greenhouse gas, through the environment.
Published Scientists discover 18 new species of gut microbes in search for origins of antibiotic resistance
(via sciencedaily.com) Original source Researchers have discovered 18 new species of Enterococcus type bacteria from soil samples collected from all corners of the globe, which may offer new clues to the origins of antibiotic-resistant infections in hospitals.
Published Measuring electrical conductivity in microorganisms, approaching understanding of microbial ecosystems
(via sciencedaily.com) Original source Researchers have developed an innovative methodology for measuring the electrical conductivity of microbial communities. This methodology holds promise for the development of batteries and electrochemical sensors using microorganisms and may serve as a pivotal tool in elucidating the role of electricity within microbial ecosystems.
Published Scientists develop novel RNA- or DNA-based substances to protect plants from viruses
(via sciencedaily.com) Original source Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study. The researchers were able to fend off a common virus using the new active substances in up to 90 per cent of cases. They also developed a method for finding substances tailored specifically to the virus. The team has now patented the method.
Published Astronomers reveal a new link between water and planet formation
(via sciencedaily.com) Original source Researchers have found water vapor in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also thought to play a significant role in planet formation. Yet, until now, we had never been able to map how water is distributed in a stable, cool disc -- the type of disc that offers the most favorable conditions for planets to form around stars.
Published Astronomers discover heavy elements after bright gamma-ray burst from neutron star merger
(via sciencedaily.com) Original source An international team of astronomers obtained observational evidence for the creation of rare heavy elements in the aftermath of a cataclysmic explosion triggered by the merger of two neutron stars.
Published A new plant's name that tells a story
(via sciencedaily.com) Original source A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years.
Published Lockdowns had an impact on gut microbes and allergies in newborns, new research reveals
(via sciencedaily.com) Original source Lockdowns imposed during the COVID-19 pandemic had an impact on the gut microbiome development of babies born during these periods according to new research. Our gut microbiome, an ecosystem of microbes that live in our digestive tract, plays an essential role in human health. The study reveals significant differences in the microbiome development of babies born during lockdown periods when compared to pre-pandemic babies.
Published 'Cosmic lighthouses' that cleared primordial fog identified with JWST
(via sciencedaily.com) Original source Scientists working with data from NASA's James Webb Space Telescope (JWST) have obtained the first full spectra of some of the earliest starlight in the universe. The images provide the clearest picture yet of very low-mass, newborn galaxies, created less than a billion years after the Big Bang, and suggest the tiny galaxies are central to the cosmic origin story.
Published Study reveals accelerated soil priming under climate warming
(via sciencedaily.com) Original source A new study highlights a crucial biosphere feedback mechanism and its effects on releasing soil carbon into the atmosphere.
Published New tool helps decipher gene behavior
(via sciencedaily.com) Original source Scientists have extensively researched the structure and sequence of genetic material and its interactions with proteins in the hope of understanding how our genetics and environment interact in diseases. This research has partly focused on 'epigenetic marks', which are chemical modifications to DNA, RNA, and the associated proteins (known as histones).
Published In fight against brain pathogens, the eyes have it
(via sciencedaily.com) Original source The eyes have been called the window to the brain. It turns out they also serve as an immunological barrier that protects the organ from pathogens and even tumors, researchers have found. In a new study, researchers showed that vaccines injected into the eyes of mice can help disable the herpes virus, a major cause of brain encephalitis. To their surprise, the vaccine activates an immune response through lymphatic vessels along the optic nerve.
Published Avian influenza virus is adapting to spread to marine mammals
(via sciencedaily.com) Original source Avian influenza virus H5N1 has adapted to spread between birds and marine mammals, finds a new study.
Published Radio waves can tune up bacteria to become life-saving medicines
(via sciencedaily.com) Original source Scientists have found a new way to alter the DNA of bacterial cells -- a process used to make many vital medicines including insulin -- much more efficiently than standard industry techniques.
Published Double trouble at chromosome ends
(via sciencedaily.com) Original source New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought.
Published Change in gene code may explain how human ancestors lost tails
(via sciencedaily.com) Original source A genetic change in our ancient ancestors may partly explain why humans don't have tails like monkeys.
Published Low-Temperature Plasma used to remove E. coli from hydroponically grown crops
(via sciencedaily.com) Original source In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.
Published New discovery shows how cells defend themselves during stressful situations
(via sciencedaily.com) Original source A recent study has unveiled an exciting discovery about how our cells defend themselves during stressful situations. The research shows that a tiny modification in the genetic material, called ac4C, acts as a crucial defender, helping cells create protective storage units known as stress granules. These stress granules safeguard important genetic instructions when the cell is facing challenges. The new findings could help shed light on relevant molecular pathways that could be targeted in disease.
Published Scientists use blue-green algae as a surrogate mother for 'meat-like' proteins
(via sciencedaily.com) Original source Researchers have not only succeeded in using blue-green algae as a surrogate mother for a new protein -- they have even coaxed the microalgae to produce 'meat fiber-like' protein strands. The achievement may be the key to sustainable foods that have both the 'right' texture and require minimal processing.
Published Microbial comics: RNA as a common language, presented in extracellular speech-bubbles
(via sciencedaily.com) Original source Decoding the conversations between microbes of hypersaline environments reveals deep insights into the origins of complex life.
