Published Lab-grown 'mini-guts' could help in development of new and more personalized treatments for Crohn's disease
(via sciencedaily.com) Original source Scientists have grown 'mini-guts' in the lab to help understand Crohn's disease, showing that 'switches' that modify DNA in gut cells play an important role in the disease and how it presents in patients. The researchers say these mini-guts could in future be used to identify the best treatment for an individual patient, allowing for more precise and personalized treatments.
Published Income inequality and carbon dioxide emissions have a complex relationship
(via sciencedaily.com) Original source Income inequality and carbon dioxide emissions for high-income nations such as the United States, Denmark and Canada are intrinsically linked -- but a new study has taken a deeper look at the connection and found this relationship is less fixed, can change over time, and differ across emission components. The findings could help countries set a course toward reducing emissions of the harmful greenhouse gas and alleviating domestic income inequality at the same time.
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 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 NASA's Webb opens new window on supernova science
(via sciencedaily.com) Original source Peering deeply into the cosmos, NASA's James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few of the newfound exploding stars are the most distant examples of their type, including those used to measure the universe's expansion rate.
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 Case studies show how quasi-governmental organizations could strengthen climate adaptation governance
(via sciencedaily.com) Original source The politicization of climate issues and the unsynchronized efforts of stakeholders are hindering the effectiveness of climate adaptation governance in the U.S. According to a new study the design characteristics of quasi-governmental organizations (QGOs) could provide insights on how to depoliticize climate information sources and foster multi-level stakeholder coordination.
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 Researchers engineer new approach for controlling thermal emission
(via sciencedaily.com) Original source If a material absorbs light, it will heat up. That heat must go somewhere, and the ability to control where and how much heat is emitted can protect or even hide such devices as satellites. An international team of researchers has published a novel method for controlling this thermal emission in Science.
Published Four-legged, dog-like robot 'sniffs' hazardous gases in inaccessible environments
(via sciencedaily.com) Original source Nightmare material or truly man's best friend? A team of researchers equipped a dog-like quadruped robot with a mechanized arm that takes air samples from potentially treacherous situations, such as an abandoned building or fire. The robot dog walks samples to a person who screens them for potentially hazardous compounds.
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 Protocol for creating 'wired miniature brains'
(via sciencedaily.com) Original source Researchers have developed -- and shared -- a process for creating brain cortical organoids -- essentially miniature artificial brains with functioning neural networks.
Published Advanced AI-based techniques scale-up solving complex combinatorial optimization problems
(via sciencedaily.com) Original source A framework based on advanced AI techniques can solve complex, computationally intensive problems faster and in a more more scalable way than state-of-the-art methods, according to a new study.
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 Researchers demonstrate the first chip-based 3D printer
(via sciencedaily.com) Original source Researchers have demonstrated the first chip-based 3D printer, a tiny device that emits reconfigurable beams of visible light into a well of resin that rapidly cures into a solid shape. The advance could enable a 3D printer small enough to fit in the palm of a person's hand.
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 Researchers create skin-inspired sensory robots to provide medical treatment
(via sciencedaily.com) Original source Scientists have created innovative soft robots equipped with electronic skins and artificial muscles, allowing them to sense their surroundings and adapt their movements in real-time.
