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 Major milestone in cutting harmful gases that deplete ozone layer and worsen global warming
(via sciencedaily.com) Original source A new study has revealed significant progress in the drive to reduce levels in the atmosphere of chemicals that destroy Earth's ozone layer, confirming the success of historic regulations limiting their production.
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 Making remanufacturing profitable
(via sciencedaily.com) Original source Returning end-of-life products to as-new condition is called remanufacturing and can be an essential element in a circular economy. But for more industrial companies to take an interest in it, remanufacturing needs to be economically viable.
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 Early life exposure to weed pollen could increase childhood asthma risk
(via sciencedaily.com) Original source A study has found children who are exposed to tree and weed pollen in urban environments are at increased risk of respiratory health problems, including asthma. While green areas in urban settings decrease exposure to air pollution, allow kids to be active, and offer positive contact to a diverse microbiota -- which in turn may help the positive development of a child's immune system -- they can also lead to the development of childhood asthma. Thankfully, trees can help mitigate this effect to some degree, thanks to their canopy.
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 Researchers use 3D visualization to predict, prevent hurricane damage
(via sciencedaily.com) Original source The researchers say 3D visualization of hurricanes and storm surges allows them to understand how flooding will impact coastal communities by allowing them to vividly see how each building and road might be impacted by a given flood.
Published Upstream and downstream: River study highlights cross-country inequities
(via sciencedaily.com) Original source New research highlights inequities between downstream and upstream countries that share the same watershed. The study outlines how international agreements can better address shared resource problems and call for greater collaboration and coordination between these international neighbors.
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 Study estimates that between 1980 and 2020, 135 million premature deaths could be linked to fine particulate matter pollution
(via sciencedaily.com) Original source A study has revealed that fine particulate matter from 1980 to 2020 was associated with approximately 135 million premature deaths globally.
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.
Published Bartonella DNA Found in Blood of Patients With Psychosis
(via sciencedaily.com) Original source A new study has found that patients diagnosed with schizophrenia or another psychotic disorder are three times more likely to have Bartonella DNA in their blood than adults without these disorders. The work further supports the idea that pathogens -- particularly vector-borne pathogens -- could play a role in mental illness.
Published Elephants have names for each other like people do, new study shows
(via sciencedaily.com) Original source Wild African elephants address each other with name-like calls, a rare ability among nonhuman animals, according to a new study. Researchers used machine learning to confirm that elephant calls contained a name-like component identifying the intended recipient, a behavior they suspected based on observation. The study suggests elephants do not imitate the receiver's call to address one another but instead use arbitrary vocal labels like humans.
