Published Virus-like nanoparticles control the multicellular organization and reproduction of host bacteria
(via sciencedaily.com) Original source Researchers have discovered that virus-like nanoparticles can promote the multicellular organization and reproduction of host bacteria. These particles, which are evolutionarily related to phages (viruses that infect bacteria), contain an enzyme that helps shape the multicellular architecture and ultimately enhances morphological differentiation.
Published Algae offer real potential as a renewable electricity source
(via sciencedaily.com) Original source The need to transition away from fossil fuels to more sustainable energy production is critical. That's why a team of researchers is looking at a potential power source that not only produces no carbon emissions but removes carbon as it works: algae.
Published Researchers create realistic virtual rodent
(via sciencedaily.com) Original source To help probe the mystery of how brains control movement, scientists have created a virtual rat with an artificial brain that can move around just like a real rodent. The researchers found that activations in the virtual control network accurately predicted neural activity measured from the brains of real rats producing the same behaviors.
Published Scientists unlock secrets of how archaea, the third domain of life, makes energy
(via sciencedaily.com) Original source An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how these tiny lifeforms make energy by consuming and producing hydrogen. This simple but dependable strategy has allowed them to thrive in some of Earth's most hostile environments for billions of years.
Published How did a satellite galaxy of the Milky Way come to be?
(via sciencedaily.com) Original source Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear. A team of physicists now offers an explanation.
Published New insights on polymicrobial infections in chronic lung diseases
(via sciencedaily.com) Original source Chronic lung diseases are often accelerated and exacerbated by polymicrobial infections. An international study has identified two types of these so-called dysbioses in cystic fibrosis. They display distinct ecology and are also likely to respond differently to treatment.
Published New discovery reveals unexpected ocean algae help cool Earth
(via sciencedaily.com) Original source A common type of ocean algae plays a significant role in producing a massively abundant compound that helps cool the Earth's climate, new research has discovered.
Published First week after birth is critical for development of senses
(via sciencedaily.com) Original source Researchers have found that the maturation of the senses for smell and touch is closely linked in mice and that this strong interaction takes place within a narrow developmental time window. These findings not only underline the importance of environmental stimuli for brain assembly in early life, but also the interdependent development of the senses.
Published Lone Star State: Tracking a low-mass star as it speeds across the Milky Way
(via sciencedaily.com) Original source Astronomers have discovered a rare hypervelocity L subdwarf star racing through the Milky Way. More remarkably, this star may be on a trajectory that causes it to leave the Milky Way altogether.
Published Breakthrough in creating cyclic peptide opens the way for new antibiotics
(via sciencedaily.com) Original source A discovery could speed up efforts to produce new antibiotics in the fight against antimicrobial resistance.
Published Brain's structure hangs in 'a delicate balance'
(via sciencedaily.com) Original source Researchers examined anatomy of neurons from humans, mice and fruit flies. They discovered that the cellular structure of the brain is at a critical point, poised between two phases. New insights could help design computational models of the brain's complexity.
Published Protein study could help researchers develop new antibiotics
(via sciencedaily.com) Original source A team has found a way to make the bacterial enzyme histidine kinase water-soluble, which could make it possible to rapidly screen potential antibiotics that might interfere with its functions.
Published Fine-tuning leaf angle with CRISPR improves sugarcane yield
(via sciencedaily.com) Original source A CABBI research team has used CRISPR/Cas9 gene editing to optimize leaf angle in sugarcane, increasing the amount of sunlight it captures and the amount of biomass it produces.
Published Two can play that game: juvenile dolphins who play together are more successful as adults
(via sciencedaily.com) Original source Juvenile social play predicts adult reproductive success in male bottlenose dolphins, a new study has found.
Published Hubble finds surprises around a star that erupted 40 years ago
(via sciencedaily.com) Original source Astronomers have used new data from NASA's Hubble Space Telescope and the retired SOFIA (Stratospheric Observatory for Infrared Astronomy) as well as archival data from other missions to revisit one of the strangest binary star systems in our galaxy -- 40 years after it burst onto the scene as a bright and long-lived nova. A nova is a star that suddenly increases its brightness tremendously and then fades away to its former obscurity, usually in a few months or years.
Published Webb telescope reveals asteroid collision in neighboring star system
(via sciencedaily.com) Original source Astronomers have captured what appears to be a snapshot of a massive collision of giant asteroids in Beta Pictoris, a neighboring star system known for its early age and tumultuous planet-forming activity.
Published How human derived RNA fragments help the Hepatitis E virus
(via sciencedaily.com) Original source Why does Hepatitis E become chronic in some patients, and why do medications not work? To find out, an international research team led by scientists from Bochum observed a patient with chronic Hepatitis E infection over a year. Repeated sequencing of the virus RNA showed that the virus incorporated various parts of the host's messenger RNA into its genome. This resulted in a replication advantage, which may have contributed to the infection becoming chronic.
Published The solar system may have passed through dense interstellar clouds 2 million years ago, altering Earth's climate
(via sciencedaily.com) Original source Astrophysicists calculate the likelihood that Earth was exposed to cold, harsh interstellar clouds, a phenomenon not previously considered in geologic climate models.
Published Gut microbes from aged mice induce inflammation in young mice, study finds
(via sciencedaily.com) Original source When scientists transplanted the gut microbes of aged mice into young 'germ-free' mice -- raised to have no gut microbes of their own -- the recipient mice experienced an increase in inflammation that parallels inflammatory processes associated with aging in humans. Young germ-free mice transplanted with microbes from other young mice had no such increase.
Published Novel Genetic Clock discovers oldest known marine plant
(via sciencedaily.com) Original source An international research team has discovered the oldest known marine plant using a novel genetic clock. This 1400-year-old seagrass clone from the Baltic Sea dates back to the Migration Period. The research project is a significant step towards better understanding and protecting marine ecosystems.
