Results of a 2018 multirocket launch at Poker Flat Research Range north of Fairbanks, Alaska, will help scientists better understand the impact of more water vapor accumulating near the fringe of the Earth's atmosphere.
"This is the first time anyone has experimentally demonstrated that cloud formation in the mesosphere is directly linked to cooling by water vapor itself," said Irfan Azeem, space physicist at Astra LLC in Louisville, Colorado, and principal investigator of the Super Soaker mission.
Materials called perovskites can be more readily incorporated into silicon-based semiconducting platforms by using a microfluidic pumping technology developed at KAUST.
The perovskites currently being explored for many applications in new technologies are diverse materials sharing the same crystalline structure as the natural mineral perovskite. These semiconducting materials show great promise in a variety of optoelectronic applications, such as light emitters, sensors and solar cells.
Collaborating with the University of Oxford, Professor Ho Yin Edwin Chan's research team from the School of Life Sciences of The Chinese University of Hong Kong (CUHK) recently unveiled the counteracting relationship between pre-mRNA-processing factor 19 (Prpf19) and exocyst complex component 7 (Exoc7) in controlling the degradation of disease protein and neurodegeneration of the rare hereditary ataxia. The research findings have been published in the prestigious scientific journal, Cell Death & Disease.
Protein misfolding contributes to the pathogenesis of SCA3
A new paper by Dr. Miki Ben-Dor and Prof. Ran Barkai from the Jacob M. Alkow Department of Archaeology at Tel Aviv University proposes an original unifying explanation for the physiological, behavioral and cultural evolution of the human species, from its first appearance about two million years ago, to the agricultural revolution (around 10,000 BCE). According to the paper, humans developed as hunters of large animals, causing their ultimate extinction.
Takeaway coffees - they're a convenient start for millions of people each day, but while the caffeine perks us up, the disposable cups drag us down, with nearly 300 billion ending up in landfill each year.
While most coffee drinkers are happy to make a switch to sustainable practices, new research from the University of South Australia shows that an absence of infrastructure and a general 'throwaway' culture is severely delaying sustainable change.
Tsukuba, Japan - Single-celled algae and animal sperm cells are widely separated in evolution but both swim in the same way, by waving their protruding hairs, called cilia or flagella. Motion is driven by molecular motors, complex assemblies of proteins that exert a force when changing shape. The motor proteins are connected to the cell's internal skeleton of microtubules; the moving force from the motor causes microtubules to slide, moving the flagella and propelling the cell.
A new method, described in a study published today in the journal Nature Communications, has the potential to boost international research efforts to find drugs that eradicate cancer at its source.
Most cancerous tissue consists of rapidly dividing cells with a limited capacity for self-renewal, meaning that the bulk of cells stop reproducing after a certain number of divisions. However, cancer stem cells can replicate indefinitely, fuelling long-term cancer growth and driving relapse.
Rutgers scientists for the first time have pinpointed the sizes of microplastics from a highly urbanized estuarine and coastal system with numerous sources of fresh water, including the Hudson River and Raritan River.
March 1, 2021 - A new paper published online in the Annals of the American Thoracic Society discusses how smoking may affect risk for COVID-19 and the types of research that are needed to better understand the link between smoking and COVID-19 risk.
CORVALLIS, Ore. - Selectively cutting trees in riparian zones to aid forest restoration can be done without adversely affecting streams' water temperature as long as the thinning isn't too intensive, new research by Oregon State University shows.
Published in PLOS One, the study led by OSU College of Agricultural Sciences graduate student David Roon is one of the few to quantify restorative thinning's effects on forest streams.
