To combat climate change, shifting from fossil fuels to clean and sustainable energy sources is imperative. A popular candidate in this regard is hydrogen, an eco-friendly fuel that produces only water when used. However, the efficient methods of hydrogen production are usually not eco-friendly. The eco-friendly alternative of splitting water with sunlight to produce hydrogen is inefficient and suffers from low stability of the photocatalyst (material that facilitates chemical reactions by absorbing light).
WEST LAFAYETTE, Ind. -- Autonomous underwater vehicles have become versatile tools for exploring the seas. But they can be disruptive to the environment or have trouble traveling through confined spaces.
Purdue University researchers are studying an alternative: highly maneuverable, low-cost underwater gliders that operate silently. Components and sensors of the glider also can be easily swapped out or added according to a wide range of mission specifications.
Unlike the Higgs boson, discovered at CERN's Large Hadron Collider in 2012 after a 40-year quest, the new particle proposed by these researchers is so heavy that it could not be produced directly even in this collider
The University of Granada is among the participants in this major scientific advancement in Theoretical Physics, which could help unravel the mysteries of dark matter
With a survival rate of only five years, the most common and aggressive form of primary brain tumor, glioblastoma multiforme, is notoriously hard to treat using current regimens that rely on surgery, radiation, chemotherapy and their combinations.
By Maria Fernanda Ziegler | Agência FAPESP – Yellow fever was the first human disease to have a licensed vaccine and has long been considered important to an understanding of how epidemics happen and should be combated. It was introduced to the Americas in the seventeenth century, and high death rates have resulted from successive outbreaks since then. Epidemics of yellow fever were associated with the slave trade, the US gold rush and settlement of the Old West, the Haitian Revolution, and construction of the Panama Canal, to cite only a few examples.
Biologically active compounds from the marine fungus Penicillium dimorphosporum protect cells from paraquat, the highly toxic herbicide with no remedy, and might enhance the action of some drugs. The fungus was isolated from soft coral collected in the South China Sea during an expedition on the Akademik Oparin research vessel. Scientists of Far Eastern Federal University (FEFU) and G. B. Elyakov Pacific Institute of Bioorganic Chemistry reported the results in Marine Drugs.
Isn't it convenient when office building windows adaptively darken according to the intensity of sunlight? Or when standard glasses turn into sunglasses under the sun and switch back as you enter a building? Such feats are possible thanks to photochromic materials, whose optical (and other) properties change radically when irradiated by visible or ultraviolet light.
Thuwal/Helsinki/Leipzig. Alkanes, an important component of fuels for combustion engines and an important class of urban trace gases, react via another reaction pathways than previously thought. These hydrocarbons, formerly called paraffins, thus produce large amounts of highly oxygenated compounds that can contribute to organic aerosol and thus to air pollution in cities.
LOS ALAMOS, N.M., February 23, 2021--A revolutionary machine-learning (ML) approach to simulate the motions of atoms in materials such as aluminum is described in this week's Nature Communications journal. This automated approach to "interatomic potential development" could transform the field of computational materials discovery.
Neuroblastoma is a cancer that develops in nerve tissue, most commonly in the glands around the kidneys. The gene MYCN is overexpressed in 20-25% of neuroblastoma, and MYCN-amplified neuroblastoma contributes to a considerable percentage of pediatric cancer-related deaths.
A UNSW Sydney-led medical research team has called for a new vaccine, improved strategies and enhanced monitoring to combat serious complications from childhood pneumonia.
The researchers examined the impact of the 13-valent pneumococcal conjugate vaccine (13vPCV) on childhood pneumonia and empyema - complicated pneumonia - after its introduction to the Australian National Immunisation Program about a decade ago.
The yellow fever mosquito (Aedes aegypti) is a main vector of deadly diseases like dengue fever, chikungunya, and the Zika virus, which result in hundreds of thousands of deaths worldwide each year. Because Ae. aegypti prefers to bite humans and there are no vaccines for many of these diseases they carry, developing methods to control these insects is imperative in the fight to control illness.
Live tracking and analyzing of the dynamics of chimeric antigen receptor (CAR) T-cells targeting cancer cells can open new avenues for the development of cancer immunotherapy. However, imaging via conventional microscopy approaches can result in cellular damage, and assessments of cell-to-cell interactions are extremely difficult and labor-intensive. When researchers applied deep learning and 3D holographic microscopy to the task, however, they not only avoided these difficultues but found that AI was better at it than humans were.
A joint research project between organizations in Japan and the US has demonstrated that zooplankton, a major food source for marine predators, can be located by following the concentration gradient of the chemical dimethyl sulfide (DMS) in ocean water and air. Currently, little is known about how marine predators search for and find enough food to maintain their body size. This study is expected to expand research into the chemical triggers of marine organisms while foraging.
If you have ever gotten up on a winter morning and thrown yourself into the arduous task of scraping frost from a windshield, a Virginia Tech lab is engaging science [IS1] that could make your life much easier. In research funded by the National Science Foundation, Associate Professor Jonathan Borekyo has led a team in developing a potential solution for frost removal by way of electrostatics.
