Published Scientists released long-term data of ground solar-induced fluorescence to improve understanding of canopy-level photosynthesis
(via sciencedaily.com) Original source A recent study utilized ground-based instruments to measure solar-induced fluorescence (SIF) that reflect plant health and photosynthesis.
Published The longer spilled oil lingers in freshwater, the more persistent compounds it produces
(via sciencedaily.com) Original source Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year there are many smaller-scale spills into lakes, rivers and oceans. The longer that oil remains in freshwater, the more chemical changes it undergoes, creating products that can persist in the environment.
Published Warming Arctic reduces dust levels in parts of the planet
(via sciencedaily.com) Original source Dust can have a huge impact on local air quality, food security, energy supply and public health. Previous studies have found that dust levels are decreasing across India, particularly northern India, the Persian Gulf Coast and much of the Middle East, but the reason has remained unclear. Researchers found that the decrease in dust can be attributed to the Arctic warming much faster than the rest of the planet, a phenomenon known as Arctic amplification. This process destabilizes the jet stream and changes storm tracks and wind patterns over the major sources of dust in West and South Asia.
Published Synthetic droplets cause a stir in the primordial soup
(via sciencedaily.com) Original source Our bodies are made up of trillions of different cells, each fulfilling their own unique function to keep us alive. How do cells move around inside these extremely complicated systems? How do they know where to go? And how did they get so complicated to begin with? Simple yet profound questions like these are at the heart of curiosity-driven basic research, which focuses on the fundamental principles of natural phenomena.
Published Scientists replace fishmeal in aquaculture with microbial protein derived from soybean processing wastewater
(via sciencedaily.com) Original source Scientists have successfully replaced half of the fishmeal protein in the diets of farmed Asian seabass with a 'single cell protein' cultivated from microbes in soybean processing wastewater, paving the way for more sustainable fish farming practices.
Published Key to efficient and stable organic solar cells
(via sciencedaily.com) Original source A team of researchers has made a significant breakthrough in the field of organic photovoltaics.
Published Diamond dust shines bright in Magnetic Resonance Imaging
(via sciencedaily.com) Original source An unexpected discovery surprised a scientist: nanometer-sized diamond particles, which were intended for a completely different purpose, shone brightly in a magnetic resonance imaging experiment -- much brighter than the actual contrast agent, the heavy metal gadolinium. Could diamond dust -- in addition to its use in drug delivery to treat tumor cells -- one day become a novel contrast agent used for MRI?
Published Deer are expanding north, and that's not good for caribou
(via sciencedaily.com) Original source In the boreal forest of Western Canada, researchers have considered that both changing climate and increased habitat alteration have enabled deer to push farther north.
Published 'Like a nanoscopic Moon lander': Scientists unlock secret of how pyramidal molecules move across surfaces
(via sciencedaily.com) Original source Scientists have watched a molecule move across a graphite surface in unprecedented detail. It turns out this particular molecule moves like a Moon lander -- and the insights hold potential for future nanotechnologies.
Published Freeze casting: A guide to creating hierarchically structured materials
(via sciencedaily.com) Original source Freeze casting is an elegant, cost-effective manufacturing technique to produce highly porous materials with custom-designed hierarchical architectures, well-defined pore orientation, and multifunctional surface structures. Freeze-cast materials are suitable for many applications, from biomedicine to environmental engineering and energy technologies.
Published How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon
(via sciencedaily.com) Original source How do birds fly in a coordinated and seemingly effortless fashion? Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.
Published Towards novel promising perovskite-type ferroelectric materials: High-pressure synthesis of rubidium niobate
(via sciencedaily.com) Original source Researchers have pioneered a breakthrough in ferroelectric material development. They've engineered a novel displacement-type ferroelectric material boasting remarkable dielectric properties. Their achievement includes the successful synthesis of rubidium niobate (RbNbO3), a compound previously deemed challenging to produce under pressures exceeding 40,000 atmospheres. Additionally, they characterized how polarization changes across a wide temperature range during phase transitions. This breakthrough can lead to new design guidelines for ferroelectric materials.
Published How electric vehicle drivers can escape range anxiety
(via sciencedaily.com) Original source Two of the biggest challenges faced by new and potential electric vehicle (EV) drivers are range anxiety and speed of charging, but these shouldn't have to be challenges at all. Researchers discovered that a change in refueling mindset, rather than improving the size or performance of the battery, could be the answer to these concerns.
Published Advanced cell atlas opens new doors in biomedical research
(via sciencedaily.com) Original source Researchers have developed a web-based platform that offers an unprecedented view of the human body at the cellular level. The aim is to create an invaluable resource for researchers worldwide to increase knowledge about human health and disease.
Published The secret to saving old books could be gluten-free glues
(via sciencedaily.com) Original source 'Bookworm' is a cute thing to call a voracious reader, but actual bookworms -- as well as microorganisms and time -- break down the flour pastes commonly used to keep old publications in one piece. Now, researchers have analyzed the proteins in wheat-based glues applied in historic bookbinding to provide insights on their adhesiveness and how they degrade. This information could help conservators restore and preserve treasured tomes for future generations.
Published How immune cells communicate to fight viruses
(via sciencedaily.com) Original source Chemokines are signalling proteins that orchestrate the interaction of immune cells against pathogens and tumors. To understand this complex network, various techniques have been developed to identify chemokine-producing cells. However, it has not yet been possible to determine which cells react to these chemokines. Researchers have now developed a new class of genetically modified mice that enables the simultaneous identification of chemokine producers and sensors.
Published Unveiling the lionfish invasion in the Mediterranean Sea
(via sciencedaily.com) Original source Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.
Published Human activities have an intense impact on Earth's deep subsurface fluid flow
