A mollusk and shrimp are two unlikely marine animals that are playing a very important role in engineering. The bodies of both animals illustrate how natural features, like the structures of their bones and shells, can be borrowed to enhance the performance of engineered structures and materials, like bridges and airplanes. This phenomenon, known as biomimetics, is helping advance structural topology research, where the microscale features found in natural systems are being mimicked.
WASHINGTON, April 20, 2021 -- Fiber optic technology is the holy grail of high-speed, long-distance telecommunications. Still, with the continuing exponential growth of internet traffic, researchers are warning of a capacity crunch.
In AVS Quantum Science, by AIP Publishing, researchers from the National Institute of Standards and Technology and the University of Maryland show how quantum-enhanced receivers could play a critical role in addressing this challenge.
Researchers at Johannes Gutenberg University Mainz (JGU) in Germany and the Institute of Molecular Biology of Barcelona in Spain have discovered how the blood plasma protein fetuin-B binds to the enzyme meprin β and used a computer model to visualize their findings. These results could lead to the development of new drugs to treat serious diseases such as Alzheimer's and cancer. Meprin β releases proteins from cell membranes, thus controlling important physiological functions in the human body. However, a dysregulation of this process can trigger the development of Alzheimer's and cancer.
Earthquake early warnings can be delivered successfully using a small network of off-the-shelf smartphones attached to building baseboards, according to a study conducted in Costa Rica last year.
In his presentation at the Seismological Society of America (SSA)'s 2021 Annual Meeting, Ben Brooks of the U.S. Geological Survey said the ASTUTI (Alerta Sismica Temprana Utilizando Teléfonos Inteligentes) network of more than 80 stations performed comparably to scientific-grade warning systems.
The lack of accountability, poor communication and insufficient planning plaguing the government’s response to the COVID-19 pandemic — especially in its early months — have roots in how the nation responded to 9/11, Hurricane Katrina and the H1N1 swine flu, a new study involving the University of Washington found.
The familiar murkiness of waters in the Gulf of Mexico can be off-putting for beachgoers visiting Galveston Island. Runoff from the Mississippi River makes its way to local beaches and causes downstream water to turn opaque and brown. Mud is one factor, and river runoff is another. However, concern tends to ratchet up a notch when pollution enters the river runoff discussion on a national scale, specifically when smaller, navigable intrastate bodies of water push pollution into larger interstate waters often involved in commerce (i.e. the Mississippi River, Great Lakes, Ohio River).
Mass extinctions are known as times of global upheaval, causing rapid losses in biodiversity that wipe out entire animal groups. Some of the doomed groups linger on before going extinct, and a team of scientists found these "dead clades walking" (DCW) are more common and long-lasting than expected.
Researchers at the University of Jyväskylä highlight how the struggles caused by the COVID-19 pandemic can guide us towards an equitable use of our shared environment and a transition towards sustainability.
WASHINGTON -- Researchers have developed new x-ray optics that can be used to harness extremely fast pulses in a package that is significantly smaller and lighter than conventional devices used to modulate x-rays. The new optics are based on microscopic chip-based devices known as microelectromechanical systems (MEMS).
People who regularly use psychoactive substances report experiencing a variety of negative impacts since the COVID-19 pandemic began, including increased usage and fear of relapse or overdose, highlighting the need for improved supports and services, including better access to safe supply programs, according to a new CAMH survey published in the International Journal of Drug Policy.
Leesburg, VA, April 20, 2021--An award-winning Scientific Electronic Exhibit to be presented at the ARRS 2021 Virtual Annual Meeting found non-contrast pituitary MRI for central precocious puberty (CPP), growth hormone deficiency (GHD), and short stature (SS) has similar diagnostic yield compared to the standard contrast-enhanced protocol.
Researchers have found a causal link between caesarean section birth, low intestinal microbiota and peanut sensitivity in infants, and they report the effect is more pronounced in children of Asian descent than others, in a recently published paper in the journal of the American Gastroenterological Association.
When disease outbreaks happen, response time in developing and distributing treatments is crucial to saving lives. Unfortunately, developing custom drugs as countermeasures is often a slow and difficult process.
A new study is the first-ever to identify the genes for creativity in Homo sapiens that distinguish modern humans from chimpanzees and Neanderthals. The research identified 267 genes that are found only in modern humans and likely play an important role in the evolution of the behavioral characteristics that set apart Homo sapiens, including creativity, self-awareness, cooperativeness, and healthy longevity.
It has been a long pursuit to develop super-resolution imaging techniques for Raman microscopy, which has intrinsic advantages of chemical specificity over the fluorescence counterpart. Despite the perceived importance and extensive research efforts, true super-resolution (defined as diffraction-unlimited) Raman imaging of biological systems in the optical far-field remains challenging due to the deficiency in sensitivity for conventional Raman scattering.
