Water quality management in the ocean often targets visible pollution sources such as sewage, rivers or ships. A new global study, led by researchers at the University of Gothenburg, reveals that invisible groundwater discharges may be just as important driving nitrogen into coastal waters.
As we enter the United Nations' Decade of the Oceans, a new research study shed light on an often overlooked source of impact on the coastal ecosystems.
In order to enable large-scale hydrogen production using solar energy, particulate photocatalysts are being researched as a simple and cost-effective solution to splitting water into hydrogen and oxygen. It is necessary to develop a photocatalyst that can efficiently use visible light, which accounts for a large part of solar energy, in the water decomposition reaction. Barium tantalum oxynitride (BaTaO2N) is an oxynitride semiconductor material that absorbs visible light up to 650 nm and has a band structure capable of decomposing water into hydrogen and oxygen.
Physicists from the University of Sussex have developed an extremely thin, large-area semiconductor surface source of terahertz, composed of just a few atomic layers and compatible with existing electronic platforms.
People are adept at discerning most of the different emotions that underlie screams, such as anger, frustration, pain, surprise or fear, finds a new study by psychologists at Emory University. Screams of happiness, however, are more often interpreted as fear when heard without any additional context, the results show.
PeerJ published the research, the first in-depth look at the human ability to decode the range of emotions tied to the acoustic cues of screams.
Researchers from Newcastle University, UK, working with colleagues at King Mongkut's University of Technology Thonburi (KMUTT) in Thailand and the Institute of Urban Environment of the Chinese Academy of Sciences, analysed samples of water and sediment taken from aquaculture ponds and nearby canals at five locations in central Thailand's coastal region.
A simple plastic water bottle isn't so simple when it comes to the traditional manufacturing process. To appear in its final form, it has to go through a multi-step journey of synthetic procedure, casting, and molding. But what if materials scientists could tap into the same biological mechanisms that create the ridges on our fingertips or the spots on a cheetah in order to manufacture something like a water bottle?
Pink Floyd's Dark Side of the Moon cover, voted the greatest classical rock album of all time, intended to portray the prism and dispersion of light into a rainbow as a certain metaphorical symbolism and a light show that was never celebrated. However, they really were not aware of the fact that this image would be used by many to help illustrate the concept of refractive index and how light changes speed and direction when it encounters a different medium.
Sausalito, Calif. (March 30, 2021) - After more than three decades of research, scientists have proven that the cancer affecting up to one in four adult California sea lions necrospied at The Marine Mammal Center in Sausalito, CA, is caused by a sexually transmitted herpesvirus. The cancer, known as sea lion urogenital carcinoma, has clear parallels to cervical cancer in humans and provides a helpful model for human cancer study.
The use of artificial intelligence (AI) is becoming more common in many branches of industry and online retailing. Traditional lines of work, such as transport logistics and driving, are developing in a similar direction although mainly out of public view. Scientists at the University of Göttingen have now investigated how efficient the use of AI can be in the commercial management of trucks. Their answer: the best option is an intelligent combination of human decision-making and AI applications. The study was published in the International Journal of Logistics Management.
In a new publication from Cardiovascular Innovations and Applications; DOI https://doi.org/10.15212/CVIA.2021.0007, Sharen Lee and Gary Tse from Laboratory of Cardiovascular Physiology, Hong Kong, HKG, China, Second Hospital of Tianjin Medical University, Tianjin, China and Xiamen Cardiovascular Hospital, Xiamen, China consider a case of atezolizumab-induced autoimmune diabetes mellitus presenting with diabetic ketoacidosis.
A study led by scientists at Hong Kong Baptist University (HKBU) has decoded the genomes of the deep-sea clam (Archivesica marissinica) and the chemoautotrophic bacteria (Candidatus Vesicomyosocius marissinica) that live in its gill epithelium cells. Through analysis of their genomic structures and profiling of their gene expression patterns, the research team revealed that symbiosis between the two partners enables the clams to thrive in extreme deep-sea environments.
The research findings have been published in the academic journal Molecular Biology and Evolution.
A new study finds that coffee pulp, a waste product of coffee production, can be used to speed up tropical forest recovery on post agricultural land. The findings are published in the British Ecological Society journal Ecological Solutions and Evidence.
In the study, researchers from ETH-Zurich and the University of Hawai`i spread 30 dump truck loads of coffee pulp on a 35 × 40m area of degraded land in Costa Rica and marked out a similar sized area without coffee pulp as a control.
Growing cities tend to run out of land for waste management and new landfill sites.
Artificial Intelligence can help city managers create more powerful long-term forecasts of solid waste volumes and landfill requirements, even with missing or inaccurate data.
UJ researchers found that a 10-neuron model produced the best 30-year forecast for municipal solid waste in a growing city.
Arctic habitats have fascinated biologists for centuries. Their species-poor insect faunas, however, provide little reward for entomologists - scientists who study insects - to justify spending several weeks or even months in the hostile environments of tundra or polar deserts. As a result, data on insects from the High Arctic islands are often based on occasional collecting and remain scarce.
WATERLOO, Ontario, March 29, 2021--A newly-published paper represents one of the most comprehensive reviews of advancements to come in contact lenses, catapulting the commonly-used medical device to applications well beyond refractive error correction.
